Yes, why not. But if they are in PDF format, how can I (re)structure
them better? Thanks.

Depends what you want to do with the floppy. I won't comment on
MS-Windows, but a single-disk FreeDOS floppy such as BALDER will
boot to FreeDOS with vfat but not ntfs.

Implement VMware ESX and VMware Consolidate Backup (or whatever their
marketing calls them today).  The price is high, but the capability for
platform consistent PIT backup is unmatched.  Of course, you need at bare
minimum a small FC or iSCSI SAN, preferably FC as it's over 4 times the
throughput and lower latency.  You can build such a SAN with a Qlogic 8 port
4Gb FC switch, FC HBAs for 4 or so servers, a Nexsan SATABoy storage array
w/2GB cache and 14x500GB drives in RAID6 for about $20k USD.  At least, *I*
could build and integrate this relatively "low end" FC SAN for that.  Add
about $5k for the VCB server hardware and its largish 6TB worth of initial
scratch space.  I assume you already have an appropriate tape library.

You'd have to contact a VMware rep for current ESX and VCB pricing.  If an
organization can afford it, it's the only way to fly, especially VCB.

No idea. Indeed, I think long-iso would be better default for this kind
of technical dates which are shown in tabular form. With fi_FI.UTF-8
locale the output of "ls -l" is difficult to read because the width of
the date column is not fixed. In practice TIME_STYLE=locale is not
usable at all (with "ls -l").

Having an option to change the default is very good, but ISO date 
representation is there precisely to avoid the date localization madness, 
so I for one would also expect as default the using of ISO date standard.

+1 for ISO as default

In any case if locales were the reasoning, pt_PT.UTF-8 oughta be "30
Mai 2010" or something when it's actually just a translation from
english, "Mai 30 2010".

Is there a way to push things into changing back?

4000 pages? Wow, I think I never opened such a document :-)

If you provide a sample link, we could run some text search performance

Also, I don't have installed Acrobat on my linux boxes, but in windows, 
there are two search facilities, "find" and "advanced search". The latter

Use TIME_STYLE=long-iso or contact the GNU coreutils upstream. First
search their mailing list archives for related discussions:

http://lists.gnu.org/archive/html/bug-coreutils/

Then maybe report about problems:

I also tried that. It fails.
That UUID belongs to /root_vg-root_lv, where the root filesystem
resides.
The UUID can be confirmed at the grub propmt issuing
grub> ls (root_vg-root_ls)

Note that `boot' is a multidisk partition (sda1 and sdb1, which assemble
md0), thus root='(md0)' makes sense from a grub point of view. And md1
is the result of assembling sda2 and sdb2. This md device has only one VG 
on top of it, root_vg, with several LVs in it, one of these LVs being my 
root_lv.

This my default menuentry now:

menuentry "Debian GNU/Linux, with Linux 2.6.32-3-686-bigmem" --class
debian --class gnu-linux --class gnu --class os {
insmod raid
insmod mdraid
insmod lvm
insmod ext2
set root='(md0)'
search --no-floppy --fs-uuid --set 785366b0-d597-4e9c-9284-b6b9161236ed
echoLoading Linux 2.6.32-3-686-bigmem ...
linux   /vmlinuz-2.6.32-3-686-bigmem root=/dev/mapper/root_vg-root_lv 
ro rootdelay=15 quiet
echoLoading initial ramdisk ...
initrd  /initrd.img-2.6.32-3-686-bigmem
}

The `set root' entry says what is *root* for grub, I understand this as: 
where are /boot/grub/grub.cfg, /vmlinuz-`uname -r` and /initrd.img-`uname -r`
So IMHO it should be called boot='(md0)' for better undestanding and
disambiguation from the *other* root in the `linux' line.
The GRUB root device is not the same as the Linux kernel root= parameter.
BTW this command is undocummented in the wiki, still uses grub-legacy's
info, which doesn't apply anymore, given the `root' command has been
replaced.

The `search' line, as stated in the grub wiki:

Search devices by file, filesystem label or filesystem UUID. If --set
is specified, the first device found is set to a variable. If HD
variable name is specified, "root" is used.

I take this to mean that the first device found _which UUID is_ 785...
(the UUID of my root_gv-root_lv) will be the `root' filesystem.

And yet another definition of `root' after the `linux' call.
That one states that:

root=/dev/mapper/root_vg-root_lv  which could be written also as:
root=LABEL=root  or even
root=UUID=785366b0-d597-4e9c-9284-b6b9161236ed

The three of them should be right. None of them work.

If a suppress the `quiet' option from the `linux' line, what I can see
is LVM initializing *before* mdadm has get its job done:

"Volume group "root_vg-root_lv not found
 Skipping volume group root_vg
 Unable to find LVM volume root_vg-swap_lv
 mdadm:/dev/md0 has been started with two drives
 mdadm:/dev/md1 has been started with two drives
 Gave up waiting fot root device."

So it looks like a timming issue *but*, I have tried to issue manually
the commands in the right order at the grub prompt:
1) insmod-ing raid, mdraid, lvm and ext2; setting root to md0; 
2) searching for devices (also a variant without this step); 
3) calling linux with the right root device 
 (all three variants of this step: dev name, UUID and LABEL and with
 different rootdelay timmings, always without `quiet') and, finally;
4) calling initrd. 

Failure again. No way root_vg to be found.

One further question: after a reboot, while at the grub screen, before 
doing anything else, if a enter the command line and type `ls' at the 
prompt, I can see all of my LVs, and listing anyone of them returns: 
device name, filesystem type, label, last modification time and UUID. 
Where does this info come from? Supossedly, there aren't mods loaded to 
read that yet, until after `insmod' loads them, are there?

It seems not working for Midnight Commander, but works fine for "ls -

I wish we had a general "switch" to set this as wide setting.

I mean, I'd like all applications (command line utilities and GUI ones), 
by default use the ISO standarized format but nowadays some do (i.e., 
Nautilus) and some don't (Icedove or Pan newsreader, for example).

Merciadri, I think that the closest you will come to this under GNOME is 
to do the following:


On the panel options, go to System/ Administration and then Services.  
This will allow you to identify those services you want available to you

A question about services

[AG]

Hello list

I have some questions about the use of some of the services that are & 
can be initiated at start up.  I see these listed via the Administration 
menu option, using GNOME on an up-to-date testing Debian system.


1. The following describes my current requirements:

This machine is a single user desktop, provides CUPS server to an 
ethernet LAN-connected client Debian machine, and both machines access 
the Internet via a dedicated hardware firewall but separately connected 
to the pre-firewall hub.


I have no need for bluetooth, sane, power management options, and I 
don't have a NFS, nor wireless.  This machine runs Tor with Tor's new 
friend, polipo, with privoxy continuing to be updated but seemingly no 
longer required by Tor.


I have KDE4 installed and Xfce4 and I use GNOME daily.  KDE4 requires MySQL.

There is an external USB drive connected to my machine which I access 
frequently so is mounted at boot up.


2.  Services currently activated at start up (according to GNOME):

alsa-utils - audi settings (I'm okay with that)
anacron - actions scheduler (needed)
atd - actions scheduler (needed)
avahi-daemon - multicast DNS service discovery (do I need this?)
cpudfrequtils (shows useful info when called up with hardinfo)
cron - actions scheduler (needed)
cups - printer service (needed)
dirmngr - ? (no idea - sounds reasonable but ...?)
exim4 - mail agent (maybe needed for POP3 and accessing GMail from my 
email client?)

hal - ? (needed, I think)
kerneloops - automated crash reports support (can't be bad)
lm-sensors - hardware monitor (probably a good thing)
loadcpufreq - ? (maybe worth having enabled?)
mysql - database server (KDE4 seems to need it and it's handy if I 
needed a decent dBase)

polipo - ? (now seemingly relied on by Tor, which I do want)
portmap - rpc mapper (wasn't this the bette noire for crackers scanning 
ports?  Anyway, do I need it for mounting/ accessing the external USB 
drive?)
pyro-nsd - ? (seemingly necessary for Python calls & as I have a number 
of Python utilities and libraries loaded, so will keep that)

rsyslog - ? (systems logging - needed)
sudo - ? (needed)
tor - ? (needed)

3.  Questions:

3.1. Do I need anacron *and* atd *and* cron?  Do they all work together 
or am I wasting resources, etc., by having all going?  How do I figure 
out which one is the safest to stop?


3.2. Given the description of my system requirements, do I need to run 
services like:

* avahi-daemon
* dirmngr
* exim4
* portmap

Thanks for any opinions you can offer.

AG

Nice idea, but all the listed services (winbind, anacron, atd,
alsa-utils, nfs-kernel-server, samba, gdm, smartmontools, exim4,
fetchmail, avahi-daemon, acpid, rsync, ssh, dbus, apache2) are already
activated. :-(

P.S.: My surname is actually `Luca' but that does not matter. This is my
fault: I misconfigured the client some years ago, and then, to be
logical with my error, I kept with it.

But I find it special that it does not go faster. Adobe wants everybody

Try the following (you don't have to be root for that):

And inspect the /tmp/rc?.d directories.


Sven, That is exactly the trick that I was looking for.
The result looks scary :-(


Why?  Only because it is unfamiliar?  Or do you have concrete indication
that the boot order is not correct?

I've been using insserv for almost two years, and when I now look at the
backup of /etc/rc?d which it made, _that_ looks scary to me, because the
order of the symlinks and their numbers appear to be without logic,
almost random.



It just is not correct. This is what the start sequence in /etc/rc6.d 
before using insserv looks like:


S20sendsigs [1]
S30rsyslog
S30urandom
S31umountnfs.sh
S35networking
S36firehol
S36ifupdown
S40umountfs
S60mdadm-raid
S60umountroot 


S90reboot

and this is what it looks like after insserv:

S01reboot  [2]
S01sendsigs
S01umountfs
S01umountnfs.sh
S01umountroot
S02rsyslog
S03mdadm-raid
S11ifupdown
S14networking
S15firehol
S19urandom

Reboot first before anything else?
So I changed that to S90reboot but still something went wrong: the root 
fs was not unmounted right because at reboot he complained.
So I changed it back to what it was before as in [1] by hardcoding the 
priorities.


Secondly insserv got invoked when I wasn't looking: by the VMware server 
installer :-(  I had rebooted using kernel 2.6.34 from kernel.org and 
installed the VMware server, to see if he had problems with that new 
kernel version. Unbeknownst to me, he invokes insserv so dependency 
based boot was no longer only a test: it was a fact.


I have tried for the last 3 hours to make [2] look like [1] using the 
script headers, but no luck thusfar, I'd be grateful for some pointers, 
how does one make [2] look like [1] not by hardcoding the priorities but 
by using the script headers?


Even if you manage that, you are changing data that you then have to 
track at every upgrade.


Thanks.

Thanks Sven, and every who replied as well.

Just for the archive, the '-C' option of mkdosfs can be used to create 
the new file system in a file instead of on a real  device, and to  
avoid  using  dd  in advance to create a file of appropriate size.

[SOLVED] Unbootable after kernel upgrade: Lilo can't load kernel

[Stephen Powell]

This is not a lilo bug.  The problem is that lilo's map installer
did not get run during the kernel upgrade process.  The fact that
the user was able to boot his old de-installed kernel is proof of
this.  The /boot/map file still pointed to the blocks in the file
system which formerly contained the old kernel and its initial RAM
file system image.  And since, fortunately, those blocks had not yet
been reused, the data was still there.  Modules which were
loaded from the initial RAM file system image loaded OK.  But once
the switch was made from the initial RAM file system to the
permanent root file system, further module loads could not be done,
since the modules had been erased.  When the user manually ran lilo's
map installer at the command line, the problem disappeared.

The real question is, "Why didn't the map installer get run during
the kernel upgrade?"  There is not sufficient data in the bug log
to determine the answer to that question, but I have observed that
"do_bootloader = yes" in /etc/kernel-img.conf no longer causes
lilo to be run when a new kernel is installed.  I believe that this
change in behavior was caused by changes to the kernel maintainer
scripts made around the time of the switch to grub version 1 as
the default boot loader.  "do_bootloader = yes" in /etc/kernel-img.conf
still causes zipl to be run on the s390 port, a port that neither
version of grub supports.  "do_bootloader = yes" should still be
specified in /etc/kernel-img.conf, however, so that "update-initramfs -u"
will cause lilo's map installer to be run when an initial RAM file
system is updated (but not when it is initially created).

So is this a bug in the kernel maintainer scripts?  Or is it a feature?
I don't know.  I'll leave that up to the kernel maintainers to decide.
A full discussion of how to make sure that lilo's map installer gets
run during the installation of a new kernel, taking into account all
types of kernels (official stock Debian kernels, custom kernels created
by make-kpkg, custom kernels created by "make deb-pkg", etc., is beyond
the scope of this bug log.  Interested readers may wish to look at my
web page on kernel building, particularly step 10, for further
information.  http://www.wowway.com/~zlinuxman/Kernel.htm  The instructions
for "customizing the Lenny environment" will work in Squeeze or Sid also,
provided that you use only official stock Debian kernels.  If you use
custom kernels in Squeeze or later, you *must* use hook scripts to ensure
that any post-installation activities, such as the creation of an initial
RAM file system, updating symlinks, or running a boot loader, take place.

The fact that you actually have any Snn* links in /etc/rc6.d is an
artifact of the old boot system with fixed numbers.  When you migrate to
dependency-based boot system, these will be converted to Knn* links (the
initscripts package special-cases runlevels 0 and 6, calling all scripts
with a stop argument, even for "start" links).

This is indeed not correct, but the conversion will turn these into Knn*
links first, and then you'll get a very different order.  Here's mine
for reference:

I'm sorry that this happened to you.

By running "dpkg-reconfigure sysv-rc".  Note that this will convert S*
links in runlevels 0 and 6 to K* links, but as I tried to explain, this
is what you want.

You don't have to do that, insserv does it for you.

Yes, but ...

I don't have anything as difficult to manage as you. But I am also far
less adept. Long ago I gave up on dist-upgrade as a thing I wanted to
do.  I think I stopped using it even before it was renamed to
dist-upgrade.  Instead, I devote a few GB of hard disk to multiple
partitions on which I can install successively newer releases of
Debian, but only the parts that change in the new release. Thanks to
HFS it is easy to determine which those are. I make a new clean
install in a newly formatted partion. If it doesn't work, I can reboot
back into what I had been running minutes before.  It took me a while
to work out all the kinks, but it is well worth the trouble.  As an
added benefit of this way, I mount the older root partition under a
special non-standard mount point in the new installation. If(When) I get
into trouble, I can refer to that partition to see how things were set up
before I started mucking about. 

I know this is a waste of disk space, but it is impossible to buy a HD
so small that it cannot hold several full installations of
Debian/GNU/Linux.

I suggest you rearrange your disks to make room for additional base-installs.
Practice doing Lenny to Lenny transitions to make sure you have your plan
fully worked out. And then, wait for Squeeze with the sure knowledge that
you can reboot back into your existing software. 

I cannot believe Grub2 will remain in its current state of disarray
when release of Squeeze finally happens. The module that finds
pre-existing installs and adds them to the boot menu seems to work but
when you do reboot at the end of the install process, the
installations that were listed as having been found are not there in
the boot menu. Just issue update-grub and reboot again. It is fixed.

Does this post give you warm fuzzies about the coming release?

Recurring warning when updating: AGAIN!

[JW Foster]

Below is a snip from the update of my Debian 'testing' system. I see
that there are again warnings that seem to be unresolved regarding
gconf2. I have been pondering if this should be filed as a bug report as
it is recurring though it does seem to be relative to some specific
upgrade & I'm not sure which one as I haven't kept records.
Both gconf2 & shared -mime-info seem to be the culprits. I know "it's
testing" but does anyone know how to fix this or any recommendations on
filing a bug report.

No, you can safely disable that service.

***
Dirmngr is a server for managing and downloading certificate revocation 
lists (CRLs) for X.509 certificates and for downloading the certificates 
themselves. Dirmngr also handles OCSP requests as an alternative to CRLs. 
Dirmngr is either invoked internally by gpgsm (from GnuPG 2) or when 
running as a system daemon through the dirmngr-client tool.

I would keep that service on.

Not needed, AFAIK you can safely disable.

Yes, it allows putting the processor into different load status (economy,

AFAIK, needed for running RPC services (such NFS).

I guess no. That is a task for udev/devicekit.

apt-cache show cron
apt-cache show anacron
apt-cache show at

To display what are they for and their priority. I would keep them all.

Avahi-daemon no, for sure. The others maybe. You need a mail agent 
(exim4, postfix or any other lightweight MTA, but at least one has to be 
installed). For dirmngr and portmap I'm not sure :-?

Even if ISO is a standard, it's not the *usual* representation of a date

The result looks scary :-(

Why?  Only because it is unfamiliar?  Or do you have concrete indication
that the boot order is not correct?

I've been using insserv for almost two years, and when I now look at the
backup of /etc/rc?d which it made, _that_ looks scary to me, because the
order of the symlinks and their numbers appear to be without logic,
almost random.


It just is not correct. This is what the start sequence in /etc/rc6.d
before using insserv looks like:

S20sendsigs [1]
S30rsyslog
S30urandom
S31umountnfs.sh
S35networking
S36firehol
S36ifupdown
S40umountfs
S60mdadm-raid
S60umountroot 


S90reboot


The fact that you actually have any Snn* links in /etc/rc6.d is an
artifact of the old boot system with fixed numbers.  When you migrate to
dependency-based boot system, these will be converted to Knn* links (the
initscripts package special-cases runlevels 0 and 6, calling all scripts
with a stop argument, even for "start" links).


and this is what it looks like after insserv:

S01reboot  [2]
S01sendsigs
S01umountfs
S01umountnfs.sh
S01umountroot
S02rsyslog
S03mdadm-raid
S11ifupdown
S14networking
S15firehol
S19urandom


This is indeed not correct, but the conversion will turn these into Knn*
links first, and then you'll get a very different order.  Here's mine
for reference:

,
| $ ls -1 /etc/rc6.d
| K01alsa-utils
| K01anacron
| K01atd
| K01gpm
| K01lpd
| K01nfs-kernel-server
| K01postfix
| K01stop-readahead-fedora
| K01timidity
| K01urandom
| K01xdm
| K02bind9
| K03sendsigs
| K04rsyslog
| K05umountnfs.sh
| K06nfs-common
| K06portmap
| K07hwclock.sh
| K07networking
| K08ifupdown
| K09umountfs
| K10umountroot
| K11reboot
| README
`


Secondly insserv got invoked when I wasn't looking: by the VMware
server installer :-(  I had rebooted using kernel 2.6.34 from
kernel.org and installed the VMware server, to see if he had problems
with that new kernel version. Unbeknownst to me, he invokes insserv so
dependency based boot was no longer only a test: it was a fact.


I'm sorry that this happened to you.


I have tried for the last 3 hours to make [2] look like [1] using the
script headers, but no luck thusfar, I'd be grateful for some
pointers, how does one make [2] look like [1] not by hardcoding the
priorities but by using the script headers?


By running "dpkg-reconfigure sysv-rc".  Note that this will convert S*
links in runlevels 0 and 6 to K* links, but as I tried to explain, this
is what you want.


Even if you manage that, you are changing data that you then have to
track at every upgrade.


You don't have to do that, insserv does it for you.



Thanks Sven, Good explanation! I will back up the system and 
"dpkg-reconfigure sysv-rc" and see what happens. My lack of 
understanding of sysv-rc, thanks again for your time.

I posted this problem over at linux1394-user mailing list (subject "Kino
and dvgrab not working with camcorder ", date 28 May 2010 11:39 PM).
Stefan Richter has been extremely helpful, and diligent, in tracking
down the problem. He has found its root and has proposed a solution.

So it is only fair to clarify that this is not a problem in Debian per
say, but has been discovered as (i) a regression in the kernel and (ii)
due to a bug in the camcorder's firmware (Sony DCR TRV25). I am sure we
can expect a solution in the new firewire stack in the linux kernel soon.

Forgot to mention: the camcorder works in an older kernel (2.6.26-2-686)
without any problems. I had to change nothing (no modules, no udev
rules) from the newer kernel scenario.

The camcorder appears as:
$> ls -altr /dev/raw*
crw-rw 1 root video 171, 0 May 30 11:04 /dev/raw1394

So rebooting in to an older kernel is a workaround for the present.

No, it's a SMTP server, meant to receive mail on port 25, for example 
from cron. You could put it to good use to relay mail you send to your 
SMTP server (gmail or ISP), assuming you don't use webmail only.

cron can do without a MTA now and if you don't ever read root's mail you 
can get rid of it, but I'd rather recommend reading root's mail :) 

You could also replace it with a forwarding MTA, that doesn't run as a 
daemon, if you don't mind sending root's mail via the internet.

anacron is useful if your machine is not on all the time, especially 
during the night, when most cronjobs are set to run.

atd is useful if you want to schedule one-time jobs, unlike cron, which 
is for jobs which have to be repeated on certain intervals.

As long as grub2 has so many missing features it should not be considered

The main problem with grub1 is the same as with lilo: there is no
upstream maintainer, and crucial parts of the code are undocumented
and not understandable¹.

So which bootloader should be the default?  Grub1 is also lacking
important features, albeit different ones than grub2 (e.g. ext4
support).

Squeeze and mobile broadband

[emigrant]

hi,
this is my first question here,
i want to know whether, mobile broad band works out of the box in
squeeze?
i use huawei ce0862 dongle to connect.

it didn't work for me in lenny (in fact i didn't find a way to initiate
a mobile broadband connection at the first place).

have things changed from then??

would i be able to connect easily to the internet?

thank you very much.

Why?  Only because it is unfamiliar?  Or do you have concrete 
indication

that the boot order is not correct?

I've been using insserv for almost two years, and when I now look at 
the
backup of /etc/rc?d which it made, _that_ looks scary to me, because 
the

order of the symlinks and their numbers appear to be without logic,
almost random.


It just is not correct. This is what the start sequence in /etc/rc6.d
before using insserv looks like:

S20sendsigs [1]
S30rsyslog
S30urandom
S31umountnfs.sh
S35networking
S36firehol
S36ifupdown
S40umountfs
S60mdadm-raid
S60umountroot
S90reboot


The fact that you actually have any Snn* links in /etc/rc6.d is an
artifact of the old boot system with fixed numbers.  When you migrate to
dependency-based boot system, these will be converted to Knn* links (the
initscripts package special-cases runlevels 0 and 6, calling all scripts
with a stop argument, even for "start" links).


and this is what it looks like after insserv:

S01reboot  [2]
S01sendsigs
S01umountfs
S01umountnfs.sh
S01umountroot
S02rsyslog
S03mdadm-raid
S11ifupdown
S14networking
S15firehol
S19urandom


This is indeed not correct, but the conversion will turn these into Knn*
links first, and then you'll get a very different order.  Here's mine
for reference:

,
| $ ls -1 /etc/rc6.d
| K01alsa-utils
| K01anacron
| K01atd
| K01gpm
| K01lpd
| K01nfs-kernel-server
| K01postfix
| K01stop-readahead-fedora
| K01timidity
| K01urandom
| K01xdm
| K02bind9
| K03sendsigs
| K04rsyslog
| K05umountnfs.sh
| K06nfs-common
| K06portmap
| K07hwclock.sh
| K07networking
| K08ifupdown
| K09umountfs
| K10umountroot
| K11reboot
| README
`


Secondly insserv got invoked when I wasn't looking: by the VMware
server installer :-(  I had rebooted using kernel 2.6.34 from
kernel.org and installed the VMware server, to see if he had problems
with that new kernel version. Unbeknownst to me, he invokes insserv so
dependency based boot was no longer only a test: it was a fact.


I'm sorry that this happened to you.


I have tried for the last 3 hours to make [2] look like [1] using the
script headers, but no luck thusfar, I'd be grateful for some
pointers, how does one make [2] look like [1] not by hardcoding the
priorities but by using the script headers?


By running "dpkg-reconfigure sysv-rc".  Note that this will convert S*
links in runlevels 0 and 6 to K* links, but as I tried to explain, this
is what you want.


Even if you manage that, you are changing data that you then have to
track at every upgrade.


You don't have to do that, insserv does it for you.



Thanks Sven, Good explanation! I will back up the system and 
"dpkg-reconfigure sysv-rc" and see what happens. My lack of 
understanding of sysv-rc, thanks again for your time.




Did the reconfigure. Boots and halts/reboots faster.
Thanks again Sven.

No sir, the localized format it's a mess.

The only date format understable by *any* user in the world is the ISO

The usual representation is very fuzzy. Look:

"May 29"... from what year? Ah, o.k. as there is no year printed it

"May 16", the same.

"Nov 14"?... ah, o.k., it's printed 2009.

"Dec 27"? oops, no "2009" printed? well, right, but 2010 cannot be

Let's try with the long iso format:

Just FTR, since I think you've posted that your transition worked,
there are a couple of other places that need to be checked for hdaX
references, e.g., if you're using crytpsetup / luks, "/etc/crypttab"
and your bootloader configuration (if you're using kernel options such
as cryptopts=source=hdaX).

That looks like a bug in the pt_PT.UTF-8 locale. de_DE.UTF-8 gets it
right with "30. Mai 2010", so ideally, the locales *should* be fully
localized and not just translated.

The "Unknown media type" messages have been discussed on the list
before. They are due to some KDE packages(s), apparently. Inspection of
the files in /usr/share/mime/packages/ should identify the culprit.

Herein lies the problem with changing bootloaders.  Your "safe recovery"
methodology (which is quite smart btw and I've used it myself over the years)
goes out the window in this case because the bootloader controls loading every
one of your parallel installations.  If the bootloader gets hosed, you can't
load any of them.  You're fscked.

Not a waste of space at all, but a very good use of a tiny percentage of the
space available on current drives.  With 500GB drives at ~$50 USD, and a
typical Debian install being ~5GB, you could have 10 parallel installations
using only 10% of the drive's space.  That's a smart investment in potential
severe headache prevention.  Ten parallel installs is extreme, but I'm simply
demonstrating the "cost" of storage aspect.

What you suggest here doesn't really come into play.  This isn't an issue of
going from Lenny to Squeeze.  This isn't about different package revs.  It's
not about Squeeze having problems and wanting to boot back into Lenny.  The
problem, in and of itself, is booting.  Period.  There is not way to test it
but to replace LILO with Grub2 and see if the system boots afterward.  I
cannot do this on production servers, obviously.  Cloning drives to play with
on a lab machine would be a good idea, but I can't take production servers
offline to clone the disks.  The only real way to test this is to build a
fresh Lenny test rig from scratch with LILO, tweak it to match my production
systems, then install Grub2 and see what, if anything, breaks, and figure out
how to get around the breakage.

I hope it's ready for prime time by then.

> Does this post give you warm fuzzies about the coming release?

I'm not worried about the release.  I've taken these machines through four
live online apt upgrades all the way back from Woody to Lenny, 4 releases,
without major issues.  However, the bootloader never changed.  LILO all the
way through.  This upgrade will be radically different in this respect.

I guess I could start looking for an aftermarket bootloader to avoid this mess
altogether, although I'd rather use a FOSS solution.  Maybe extlinux.  From
what others have said here it shows some promise.

But at least grub1 is working in a wider field than grub2. And lilo is 
still working, too. Maybe not with the current Debian kernel, but it 
works for people building their own kernel.



So which bootloader should be the default?  Grub1 is also lacking
important features, albeit different ones than grub2 (e.g. ext4
support).


Maybe, but ext4 support is not really crucial. Simply make /boot ext2.

I would say, the default bootloader should be grub1, expert installation 
can offer grub2 as well. Lilo should be in the distribution as well, so 
people can switch after installation. At least for the next release.

Yes, but it probably requires a little setup.  First of all, if the
modem is a "flip-flop" device, you will need to get usb_modeswitch to
switch the modem from storage mode to modem mode.  Go to the following
link to read up on these devices and verify your dongle is supported.

http://www.draisberghof.de/usb_modeswitch

If the modem is not a "flip-flop" device, things get simpler, but I
strongly suspect the device you have is a "flip-flop" device.  Assuming
it is, you will need to download usb_modeswitch, use apt-get to obtain
pppd and probably a front-end for dialing.  There are a number
available, and which one you use depends on your personal tastes, the
desktop interface you are using, and how you will be using the device.

If you choose,it's pretty simple to write a script which loads at boot
time and waits for the USB dongle to be inserted, then configures the
dongle and automatically connects to the internet.  Otherwise, you can
create a simpler script which you run manually whenever you want to
access the internet.  You could also create a hybrid setup which
configures the modem whenever it is inserted, but does not dial out. 
Then you can initiate a dial-out connection when you want to connect. 
It's also possible to have ppp wait for an attempt to access the
internet before dialing out.  It all depends on what you want to do.

I haven't tried that yet. 

First thing would be to know if the bootloader is to blame for not
having a bootable system. As of now, it would be some timming issues
related to initramfs-tools' scripts (wild guess).

Then, I'd need to know if LILO supports the configuration described
before, i.e., md0 contains /boot and md1 contains LVs, one of them
being /dev/mapper/root_vg-root_lv.

After that, I'd need to test the proper way to install/uninstall
software from an unbootable machine. I guess d-i allows installing
LILO on top of grub.
The purpose is either reinstalling grub-pc, downgrading to grub-legacy, 
or installing LILO.
Other option would be using rescueCD, chroot into my system and install 
from there. Suggestions are welcome.

But first I'll need to refresh my LILO skills. It's been a while :)

I have a question related to this: recently the screen on a dual boot
(XP/Lenny) laptop got busted pretty badly (almost to the point where grub1's
blue splash screen menu is not visible at all), and since the primary
purpose of this laptop is now to boot to XP to use Netflix's Microsoft
Silverlight-based movie player while connected to an hdtv for on-line movie
watching, I just booted to Lenny, changed the "default=0" value to
"default=3" in /boot/grub/menu.lst so it now boots to XP by default.  My
limited experience with grub2 in Squeeze didn't appear to have this ability,
so what would I have done in this case?  Would I be fscked?

Mark

It's still there, just moved. Edit /etc/default/grub, change
GRUB_DEFAULT to 3 and run update-grub.

I almost missed this thread, but it's a good thing I didn't.  I had been
using LC_TIME=en_DK.UTF-8 to get ISO format, but at some point that
stopped working, and I couldn't figure out what had happened.

And I have to agree with Camaleón and Ron that the ISO
format is a lot less confusing.

Having /boot on a separate partition for robustness, security or 
advanced features (encrypted LVM and stuff) is one thing, but having it 
because the default bootloader doesn't support current (ext4) and future 
(btrfs) filesystems seems like a hack to me.

Is it just me or does this sound like the KDE3 -> KDE4 debate all over 
again?

Don't get me wrong, I've had my part of headaches with grub2 (I switched 
quite early), but most are fixed, so grub2 does almost everything *I* 
need. Also, the config has become so complicated you need another config 
file (/etc/default/grub) to configure how it will be generated :(

I read grub2 is still missing features (like simultaneous display on a 
serial console and VGA), and it is (still?) incompatible with some 
software (Stephen's case), but we have to face it:

* LILO is not developed anymore
* Grub1 is not developed anymore

Unless there are people interested in further developing those code 
bases they will be gone sooner or later. And my feeling (as a 
non-programmer) is that they have become unmaintainable, or at least it 
has become too much work compared to writing something from scratch 
(grub2, extlinux, ...).

AFAICT, the only thing that we as users can do (short of putting up 
bounties) is to push for the missing features to be implemented and the 
bugs to be fixed. But none of this will happen unless we are at least 
willing to *test* the new stuff. At least the regulars on this list 
should know how to recover from an unbootable system, or not?

Andrei

Booting from an SD card?

[Marc Shapiro]

My wife has an early eeepc with a 4GB SSD running Xandros.  She would like to 
change the OS so that she can install other software easily.  I have a newer 
eeepc with a 160GB HD that came with the OS that must not be named and now also 
has Eeebuntu 3.0.

I wanted to install Debian on my eeepc.

On mine, I installed Lenny, then upgraded to Squeeze to get the 2.6.32 kernel 
so that all of the hardware would work properly.  So far, so good.  Then, after 
a dist-upgrade, the wireless started to have problems.  I could connect 
anywhere EXCEPT at home.  Unsecured, or not, I could connect when not at home.  
My home wireless, with WEP security, would not connect.

I came across a site with with a Lenny installer but with the 2.6.32 kernel.  I 
created a 4 GB partition on my eeepc to simulate what the installation would be 
like on my wife's eeepc and how much space could be made available with only a 
4 GB SSD.  I did the install, updated grub, installed Gnome and rebooted.  
Everything worked fine, including connecting to my wireless network at home.  
Life is good.  I expect to blow away the Squeeze install that will not connect 
to my wireless, and replace it with this Lenny install.  I can do a 
dist-upgrade when Squeeze goes stable.

Now, I have a 4 GB SD card that I want to install Lenny on, just like the 
installation to my hard drive.  That way, my wife can try it out on her eeepc 
WITHOUT MAKING ANY CHANGES TO HER HD.  I have gone through the install, but can 
not boot from it.  I am 99% certain that it is just a case of getting grub 
properly installed on the SD card.  From MY pc, how do I install grub on the SD 
card to that Lenny can boot directly from the SD card (on my box, or my wife's) 
without affecting the booting of my machine, or needing to change anything on 
my wife's machine?

I expect that I will need to make changes to /etc/grub/menu.lst on my box, then 
run 'grub-install' to install grub on the SD card, and restore the original 
/etc/grub/menu.lst for my box.  I also expect that I may need to make changes 
to /etc/grub/menu.lst on the SD card.  My problem is that I hafe used LILO 
since Debian Bo (and am by NO means a bootloader guru) and I do not know what 
changes need to be made to  /etc/grub/menu.lst on either my box, or the SD 
card, to make this work.

Can anyone help me with this?

You example shows only dates where it is quite obvious what date format 
is used. Let me see...

-rwx-- 1 amp amp 891837 2010-05-03 22:55 03052010065.jpg
-rwx-- 1 amp amp 733361 2010-05-03 22:55 03052010066.jpg

Can you tell if these files were created 5th march or 3rd may? How (I'd 
really like to know)?

No.  They want everybody who creates "content" to buy Acrobat.  Giving

And so they market it heavily.  Thus the Web sites that say "To read

I've never heard of a -dd-mm format. All the other formats usually
put the year at the end, and if they don't, they're probably using
slashes or something else instead of hyphens. That's sufficient to
distinguish the ISO format from the rest, I think.

At least for Romanian it's not a bug in the locale, but rather missing 
feature, because only %c and %x are defined. Neither are suitable for ls 
(%c includes the weekday and %x doesn't include the time) so it is using 
it's own format. I'll report a bug for Romanian.

Sure, but I can't tell for sure unless I read strftime(3) or so...
For me dd mmm  is very clear, but I don't like the suppressing of 
the current year either :(

problem running kernel compiled on different machine

[H.S.]

I am testing a patch for the Debian kernel (regarding the firewire bug I
reported earlier in this list). I have been sent the patch and I
followed the Debian way of compiling the kernel after patching the source.

The kernel was compiled (and the deb created) on an AMD64 bit machine
which is running a 32 bit kernel (2.6.32-5-686-bigmem). The deb created
can be installed without any problems on this host machine. However, if
I try to install that deb on a target machine (Intell 32 bit processor),
the installation gives errors and I cannot boot into that kernel:

$> sudo dpkg -i

Anybody know why I am getting this error? Also AFAIK, a 32 bit kernel
can be compiled on a 64 bit machine as long as it is running a 32 bit
OS. Correct?



The steps that I followed to compile and create the deb of the custom
kernel:
#
Downloaded kernel source:
$> sudo aptitude install linux-source-2.6.32

Removed symlink in /usr/src directory:
$> rm linux


Expanded the downloaded source tar ball:
$> tar jxf linux-source-2.6.32.tar.bz2


Now create the symlink
$> ln -s /path/to/linux-source-2.6.32 linux

So now "linux" points to our current kernel source tree.

Check for requirements by running the script in the kernel tree:
$> cd linux/scripts/
$> ./ver_linux
If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.
NOTE: fdformat was not found (but we don't need it .. I think).


Use menuconfig to load the current config from /boot and save and exit
$> cp /boot/config-`uname -r` ./.config
$> make oldconfig
(no questions were asked by the last command)


Save the patch to be applied in a directory. I put it in
/usr/src/linux/patches_hs/firewire_trv25_bug.patch

Then apply the patch
$> patch --verbose -p1 < patches-hs/firewire_trv25_bug.patch


Start build commands sequence:
$> fakeroot make-kpkg clean

Use 2 cores:
$> export CONCURRENCY_LEVEL=2


$> time nice fakeroot make-kpkg --append-to-version=.100528-firewire
kernel_image

Remove symlink:
$> rm /usr/src/linux
rm: remove symbolic link `linux'? y

Force reinstall of /etc files without purge/install cycle?

[Todd A. Jacobs]

I can't find an option within aptitude to force a reinstall of /etc
files. I know that aptitude will not overwrite them by default, but
isn't there a way to force a package's conf files back to a pristine
state?

The purge/install cycle isn't always an option, since in many cases it
will want to uninstall all of gnome or kde.

The question is, "Does he have a PCMCIA card or a dedicated USB modem,
or is it one of the multi-function USB dongles?"  If the latter, he's
going to need usb_modeswitch.

hi,
thanks all for your replies.
what i can say of my modem is,
its like a pen drive in shape and is only used as a modem. 
and it work out of the box in ubuntu and pclos (those are the two
distros iv checked so far)

The purge/install cycle isn't always an option, since in many cases it

The option will likely be the --force-confmiss dpkg option.

From the IRC bot:

The reason you have to use dpkg --force-confmiss is because whenever 
your config files () are gone, dpkg assumes you deleted them 
on purpose, and that you want them to stay deleted.  You can also 
reinstall them using the following apt-get line: apt-get -o 
DPkg::Options::="--force-confmiss" --reinstall install ; or 
using aptitude, aptitude -o DPkg::Options::="--force-confmiss" reinstall 
;

I see what you mean. Any date format that only uses numbers risks
confusing the user about which number is the month and which is the day.
The point of using an international standard for dates is to avoid that
confusion, but "May 30 2010" is clear as long as you understand "May",
so I guess it's a moot point in this case.

Sorry about splitting this into two emails, but the reason that it wants 
to remove those packages is because they are "automatically installed" 
either via recommends or depends. You can mark them as manually 
installed with aptitude unmarkauto . Sometimes you can easily 
unmark many packages at once with aptitude keep-all (by removing the 
package with dpkg so that the other actions are "pending" as far as 
aptitude is concerned).

That doesn't really say anything.  With the modem plugged in, what is
the result of

`lsusb -v`

Automatic partial archive mirroring

[Cameron Hutchison]

I have a few debian unstable boxes that I like to keep up-to-date.

Currently, I run apt-cacher-ng (a proxy for apt-get which stores
packages so they don't need to be downloaded again) on my gateway box
(lenny 32-bit), so I don't double download from my couple of other boxes
(sid 64-bit). This works well enough, but I want to make it better.

My internet connection has an off-peak period (2am-8am) where downloads
are not counted in the monthly quota. I want my downloads to occur
during this window, automatically.

The problem is that the sid boxes are not powered-up during this window
so I cannot just simply schedule a cronjob to do an apt-get -d
dist-upgrade.

I would like my lenny box to do this on behalf of my sid boxes. I dont
really want to mirror the whole archive. Is there some way to do an
intelligent partial mirror of the archive of what is installed on other
boxes, without too much overhead of managing a package list? (i.e. I dont
want to have to manually update some package list on my lenny box when I
install a new package on a sid box).

I've looked at apt-proxy, apt-cacher, apt-cacher-ng and approx, but they
all appear to download on demand, not according to a schedule.

I've never heard of a -dd-mm format. All the other formats usually
put the year at the end, and if they don't, they're probably using
slashes or something else instead of hyphens. That's sufficient to
distinguish the ISO format from the rest, I think.



DD-AAA- is common in the US Navy.  It sucks, though, as a 
collating format.

Yep, it's a Huawei E220.  If you will look on the link I sent you, you
will see it there.  It's a "flip-flop" device, also called "Zero-CD". 
When first inserted into a USB port, it is a drive device, similar to a
USB "thumbdrive".  It contains the software windows needs to load in
order to access the device.  Note the description:

Interface Descriptor:
  bLength 9
  bDescriptorType 4
  bInterfaceNumber3
  bAlternateSetting   0
  bNumEndpoints   2
  bInterfaceClass 8 Mass Storage
  bInterfaceSubClass  6 SCSI
  bInterfaceProtocol 80 Bulk (Zip)

The dongle looks like a SCSI device to the OS.  It needs to have its
mode switched so it looks and acts like a modem (or in general whatever
the secondary device might be), rather than a USB drive.  That's the
purpose of usb_modeswitch.  After the switch takes place, it will look
and act like a usb dial-up modem as far as Linux is concerned. (Some
dongles also have drive devices built in to read and write memory
sticks as well as their modem function.) Usb-modeswitch and
usb-modeswitch-data are both part of the Debian "Squeeze" distro,
although it doesn't look as if they are loaded automatically.  You will
need to use apt-get (or aptitude, or synaptic, ...) to install them. 
Once usb_modeswitch is run, the output of lsusb will show something
like:

Well, first of all, even if it is not needed now, it may be in the
future.  To answer your question, however, it was needed because the
underlying array suffered a catastrophic failure, and has since been
rebuilt.  Having rebuilt the array, and knowing that at least some data
had possibly been lost at the block device level, it is at least
prudent to double-check the health of the file system structures. 
Indeed, xfs_repair found and repaired some corrupted structures.  The
files were extracted and re-written to the drive from storage using
rsync.

The simple answer to my original question was, "xfsprogs".  Doing a
synaptic search for "xfs" returns far, far too many results through
which to easily sift, and searching for "xfs_repair" returns none at
all.

Some more info. I tried the --initrd this time while compiling the
kernel with the above mentioned patch. So different.

What I actually get while booting in the new kernel is a problem with
ext3 or something where the system cannot find ext3 and cannot mount my
partitions. The messages are similar to this (copied from a post elsewhere):
fsck.ext3: no such file or directory while trying to open /dev/hda4
/dev/hda4
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else) then the superblock


This is not the exact working, but close to what I get during the
reboot. The system than asks for root password for maintenance. I
eventually have to force a hardware restart of the system.

My next step is compile the ext3 support in the kernel and not as a
module. Currently, it is:
CONFIG_EXT3_FS=m
CONFIG_EXT3_DEFAULTS_TO_ORDERED=y
CONFIG_EXT3_FS_XATTR=y
CONFIG_EXT3_FS_POSIX_ACL=y
CONFIG_EXT3_FS_SECURITY=y

I will change that to:
CONFIG_EXT3_FS=y


But what beats me is that the host machine has no problem with the
current config and boot properly.

Any further info as to what I am missing here?

The meta-answer to your original question is http://packages.debian.org
from which you can search the contents of packages if you know what
file you're looking for. At the bottom of that page is a section titled
"Search the contents of packages".

It's so useful that I have a iceweasel/firefox smart bookmark set up for
it, so I can just type "dpcs xfs_repair" into my address bar and I get
the answer you were looking for (dpcs == debian package content search)

You could use use the output of 'dpkg --get-selections' on the Sid
boxes, pruning it using grep or similar to keep only the lines ending
with 'install'.  Combine the results from the various Sid boxes, and
then have the gateway box get those packages.  This could be scripted
easily enough, and there would be no need for manually updating
anything.
