connecting cable modem through usb port

[Sandip Sandip]

Hello all,

I have an old debian 2.4x kernel machine. I want to connect a cable modem 
through the usb port.

CDCEther support is on. When the machine is up and running cable modem LEDs 
show PC connection.

But I am not able to access internet. What is missing? Do I need to set-up/ 
configure anythine more?

I do not know if I have provided enough information or what more information 
will be needed.

Thanks in advance.

Nmap shows port 21 is open with no ftp daemon installed.

[Rod James Bio]

Hi, I've been wondering about my friends case. Seems that when he 
nmapped his machine port 21 is open, but there is no ftp daemon 
installed. He tried

"lsof -i :21"
but it did not return anything. He also tried
"netstat -an | grep 21"
also nothing.
So he asked other people and they told him that his machine was hacked. 
The lsof and netstat was modified. The port 21 was a backdoor placed by 
the hacker. Now I am not really contented with this answers. Any 
suggestions?

Try
 'telnet your.friends.ip 21'
if that works, something is definitely wrong with your friends pc.
If so, check the process list and see if you find anything you don't 
recognize. Kill that process, and try to telnet again. Do all of this 
with only a local network connection, so nobody from the internet can 
reach the possibly hijacked pc.
However, when hacked reinstalling might be the fastest way to get rid of 
any malicious software.

I wouldn't discount that possibility, but 2 thoughts come to mind:

netstat -lnpt (as root) will give far less redundant info - just what is
listening on tcp ports, including process names - so it's easier to
search through.

Was the nmap run directly on hte same network as the machine in
question? Not through a router, cable modem, or other device that could
have been getting in the way?

Oh, and some others ..

Perhaps running tcpdump on the machine while connecting to it (with nmap
or whatever) will show whether the traffic is actually getting to the
machine?

Oh - and you could try copying on a netstat and/or lsof binary, from
another machine (of the same architecture).

AFAIK you will have to do something like pppconfig to make a ppp

Well I did some test on my own port tcp 443 does show on my machine by 
nmapping(is this a valid verb?hehe)  from other network but when I do 
this in the same network it doesnt show at all. netstat does not show 
anything. Anyway thanks for the suggestion.

Not pppconfig.  For a DSL modem configured as a bridge (most default to
router these days) he would need to run pppoeconf but I don't think that
any cable providers use PPPoE.

Re: Nmap shows port 21 is open with no ftp daemon installed.

[John Hasler]

Does nmap claim there is actually something listening on port 21 or is it
that the port is simply not "stealthed"?  Post the actual nmap output.
Some security sites (such as www.grc.com) make the (IMHO bogus) claim that
not having all ports "stealthed" is a security risk.  Your friend may have
seen this and misunderstood.

It does not seem plausible that a cracker would install a rootkit that
would listen on the standard port.  Do you have any reason to believe that
these other people know what they are talking about?

That's the thing that bothers me those people that suggested him this 
jumped into the conclusion with asking or doing any verification or 
maybe a previous experience from others. They just plainly told him that 
he was "hacked" and any binary(netstat, lsof, etc) that may help him had 
been replaced.


Anyway I just got another lead on his situation. I learned from my 
seniors from there past experience this may had been a bug in the Cisco 
IOS version that was between the user and the server. Anyway thanks for

Of course, we are missing the point. No, it is not 30 minutes like my eyes

number. I live at GMT + 2. Add one for daylight savings time.

However, I have never used GMT (universal) time to save my system time. So why 
is this happening now? Ntpdate has not been upgraded past few days.

Program for quoting text like in email?

Can anyone recommend a program/shell script/editor plugin etc, that
can take arbitrary text as input and quote it like email programs
quote emails with a preceding "> " character?

I'm about to reply to a very long facebook message and want to quote
it and make inline replies. But facebook only supports top-posting.
I'd like to cut-n-paste the text I wish to reply, quote it with "> "
and then cut-n-paste it back into my facebook reply message. I'd also
like line breaks to be put in once every 80 characters (email
standard?).

I use Debian Lenny.

Re: Program for quoting text like in email?

[Jeff Soules]

While it's not terribly good code, the attached perl script should do
what you want.

It will expect file names as the input, and will output to stdout; you
will need to redirect to a file if you want to save it.  So do
something like:

$ perl quoter.pl Guy_On_The_Internet.txt  >quoted-GOTI.txt

where "Guy_On_The_Internet.txt" is the text you want to quote, in a
file.  You can change the quote character and the number of columns by
editing the values at the top of the script.

I assume that input paragraphs come in blocks (i.e. a blank line
between paragraphs) and that you want to keep paragraphs together, but
don't care about how lines are wrapped.  Output will have block
paragraphs, too.

I hope I'm not helping perpetuate some facebook flame war...


best,
Jeff

p.s.
I'm stuck on a windows machine right now, so please ignore the weird
carriage returns in the script text.

Thanks for this solution; I'll use it as a backup solution in case no
one suggests a program that is in Debians stable repository. I want to
get automatic security updates wherever possible.

I tried medit per your recommendation. The quote feature there was
however intended as quoting programming code, i.e adding /* */ around
code. I could not find an email quoting feature there though.

How about passing the text through fmt -w 80|sed 's/^/> //'?
(Untested). That should do what you desire, as fmt would format the
paragraphs, and sed would substitute every beginning of line with a ">
".

Thanks. Yes, you assumed correctly and it worked as you and I intended.

Hehe, don't worry. It's a civil discussion. However it just struck me
that the person on the other end don't have this script and she'd have
to do this manually. Hmm.. I could always suggest that we change to
communicating through email instead I suppose. Your script will in any
case be very useful to me while in facebook. Thanks for taking your
time to write it for me!

No problem. I used the "tofrodos" debian package to quickly convert it
into "linux" format.

I skimmed your script searching for any "rm -rf /" and such and am
happy to report that it is short, readable and does no nasty stuff.
Thanks; I'll be using your solution to my problem.

I got this output:

sed: -e expression #1, char 8: unknown option to `s'
to...@todu:~/code$

However, thanks for letting me know about the "fmt" command. I hadn't
heard of it before. I'll experiment with your solution too, later
though, as I also have to write my long postponed facebook reply ;).

OK, so I guess it should be sed 's/^/> /'. Anyway, experiment this
method too, sometime. It's fun to know the possibilities with sed, awk
and friends.

Personally, I create a 1G partition for root and boot, and then allocate
everything else as a single PE. I generally start with around 1G for
/tmp, 10G each for /usr and /var, and 20G for /home, and then grow the
filesystems as I need them. Oh, I usually put swap on LVM too.

I'm sure your mileage will vary, and you'll find something that works

[OT] SQL Syntax Error '????????????????'

[Harry Rickards]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

I know this is off-topic, but I don't really want to have to subscribe
to or constantly read the MySQL mailing lists, and the IRC channel's no
help.

I've written some sample code in Java that connects to localhost using
the MySQL JDBC. I've tried multiple variations of the code, but even
when using the proper code from MySQL's website, I get the following error:

SQLException: You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax to
use near '' at line 1
SQLState: 42000
VendorError: 1064


I don't know where the question marks are coming from, as there aren't
even any question marks in the code. The code is at
http://github.com/l33tmyst/dtelectrics/blob/master/src/connect.java, and
if it's any help I'm using Eclipse 3.4.2 on Debian Sid. The java version is:

rsync and Windows backups on a Debian box and permissions

[H.S.]

Hello,

I have a Debian box (running Testing) which rsyncs some directories from
a Windows laptop (running XP on an ntfs partition) to a partition on a
local disk on the Debian box.

The Debian box uses rsync via ssh connection made with the XP box which
has cygwin and ssh server installed. The user used to do the ssh
connection is an administrator on the XP box ('root'). The script is
running from the root account on the Debian box.

The command is something like this:
rsync --delete --modify-window=10  --force -Rvaue ssh
--exclude-from=$EXCLUDESFILE --progress \
xp-box:"/cygdrive/c/Documents\ and\ Settings/user1
/cygdrive/c/Documents\ and\ Settings/user2" /mnt/backups/xp-daily-00;

where $EXCLUDESFILE is a variable defined with the path to the excludes
files on the Debian box.

Now, this all works very well for making the backups.

However, the permissions of the files pulled from the XP box to the
Debian box are the same as on the XP box. The same two users, user1 and
user2, also exist on the Debian box. However, the gids and uids of these
users are different on the XP box and on the Debian box. So the users
cannot browse their own directories (backups) from within the Debian box
(permissions denied).

This is a problem if a user wants to browse, or recover files from, his
backups by connecting from the XP box to the Debian box using ssh
(because then the user's gid and uid are Debian numbers, not the XP, or
cygwin on XP, numbers).

Any ideas how I get around this problem?

Thanks.

It's mdadm being "smart".

Evidently, something about the raid5 personality makes it faster to sync a 
single disk rather than to sync across the whole array.[1]  So, unless given 
the "-f" flag, mdadm creates all RAID 5 arrays as "X-1" synced disks and one 
spare.  Once anything is written to the array, it will start "recovery" of 
the spare.

You can either let mdadm create it it with one more spare than you expect, 
or you can force the behavior with "-f".  The former will be faster.

IIRC, this is all documented on in the mdadm man page.  It's a long read, 
but I'm pretty sure it is in there.

[1] I'm not sure why this is.  When doing the initial RAID 5 sync you should 
be able to spread writes across all the disks, and sync very quickly.  
However, the way mdadm does it, all the writes go to a single disk and it's 
sustained write speed becomes a bottleneck.

Couldn't you add at the end of the script to chown the directories to

I was thinking on the same lines. Changing the owner using the uid
should work.

I am still in the process of building this script. I am going to add
other XP directories as well that will be backed up. I am not sure how
the permissions in Windows really work as far as ownership is concerned.
If a user1's directory has some file owned by another user but readable
by user1, I would want to preserve that ownership.

Further, I would also need to get the uid's of the users involved. I
would prefer it to be automatic (in case I add more users to be backed
up). Perhaps ssh can be used in some way to get this information from
the Windows machine.

Finally, this just occured to me, perhaps it is possible the uid's and
gid'd see by the Debian machine in the XP machine are created by cygwin?
I am not sure. If this is case, I could modify the account information
in Cygwin to reflect the number scheme use din Debian (I think Cygwin
uses gid and uid numbers scheme from Redhat).

Thanks.

a) Don't do that.  Have the uid/gids be the same on the MS
and Debian sides.

b) Use --numeric-ids in the rsync script and after it finishes
use find -uid and chown to change the uids to the "right" value.
(Likewise for gids.)

c) Have the users recover/browse their backups with samba
instead of ssh and have samba map the uids/gids "properly".

I have done some testing, but havn't been able to resolve the issue,
but as following:
In firefox and xchat, no AltGr combo is possible;
In Gnome-terminal and in gvim, all but tilde works
In xterm, everything works
Same issue both in xfce4 and gnome, also with an pristine user.

Listing held packages for which there are upgrades

[Karl O. Pinc]

Hi,

On etch when I did an 'aptitude upgrade' it would show
the packages on hold that would have been upgraded
but were held back.  On lenny this no longer happens.

How do I get a list of those packages, and only those
packages, that would be upgraded if they were not on hold?

FYI I want this mostly because I have too many systems
to apply security updates to manually.   So I've a cron
job that regularly does updates from the security team
repository.  However I do not want critical packages,
e.g. the kernel, upgraded by an automatic process.
I put the packages I want to manually review on hold.
I rely on the output from the cron jobs to notify me
when there are updates available for such packages.
Unlike, say the security-announce email list, the
cron jobs keep emailing me until I apply the latest
upgrades.  I can miss an email on occasion and not have
to worry about missing an irreplaceable message.

Thank you.

'aptitude safe-upgrade' will upgrade safely, and will sometimes hold
back packages. 'aptitude dist-upgrade' will not. I think upgrade now
goes to safe-upgrade.

Neither will upgrade packages that have been put on hold
with "aptitude hold".  That's what I'm asking about.

Sorry for the lack of clarity.

'aptitude safe-upgrade' will upgrade safely, and will sometimes hold
back packages. 'aptitude dist-upgrade' will not. I think upgrade now
goes to safe-upgrade.


Neither will upgrade packages that have been put on hold
with "aptitude hold".  That's what I'm asking about.


Now that I think of it I'd like to see a listing of
packages that have
been held back for any reason, both those held because
I manually put the on hold and those that are held back
by aptitude for reasons of it's own when a "safe-upgrade"
is done.  Either way I'll need to manually look at upgrading.

can't install etch on new machine

[shadesofgray]

I have the CD set. It was installed fine on my old machine. I'm trying to
install on a new pc. It is a Dell with a dvd/cd drive (TSST corp). On the
first cd it asks for the cd, but it is already reading the cd! And I can't
get past this, even when it asks for a list of cd's and I select none.

 mean it can read the cd - who cares if its not one on its list? How do I
do the install?

Thanks,

Bob

It seems this is no longer possible.  From the NEWS entry for aptitude
0.4.11:

* At the command-line prompt, don't list packages that aren't
  being upgraded unless the user tried to upgrade them.  e.g.,
  "aptitude install foo" will no longer spew the entire list of
  pending upgrades to the terminal.

At least aptitude will tell you how many packages are not upgraded:

,
| % LANG=C aptitude -s safe-upgrade 
| Reading package lists... Done
| Building dependency tree   
| Reading state information... Done
| Reading extended state information  
| Initializing package states... Done
| Reading task descriptions... Done  
| Resolving dependencies...
| The following packages have been kept back:
|  [...]
| The following packages will be upgraded:
|  [...]
| 4 packages upgraded, 0 newly installed, 0 to remove and 22 not upgraded.
| Need to get 1445kB of archives. After unpacking 8192B will be freed.
| Do you want to continue? [Y/n/?] 
| Would download/install/remove packages.
`

Maybe you can adjust your script to mail you if the number of not
upgraded packages is > 0 ?

Yup.

You don't have to use samba, it's just nice for MS Windows users.

FYI, somebody must have done this before so there's probably a
best-practices on the net, somewhere.

Does anyone else consider this a bug?

[JW]

There's a new "feature" of Lenny that keeps catching me off guard. I might be 
wrong but I don't remember Etch ever doing this to me.

It goes like this:

1. Perform a new Lenny install of the "standard package set" (no Xorg) (I 
always use net installs but I assume it's the same no matter what)

2. Immediately install ssh and configure a static IP address

3. Restart networking: /etc/init.d/networking restart

4. Start some services and and jobs on the server that make use of the network  
(start an scp or rsync of a large data set over the network is an especially 
good example ;-)  )

5. Walk away assuming the server will continue performing those tasks

6. Come back later to check on the server and discover that you can't log in 
via ssh.

7. Log into the console to see what's going on and discover that your 
scp/rsync and other network tasks have failed because dhcpclient is still 
running from the initial install's automatic DHCP network detect and had 
moved the server BACK to a DHCP address after the static network config. Mind 
you, the install does not ASK if you want DHCP or static addressing during 
setup.

Work around: Either kill dhcpclient or restart the server to get rid of it. 
Problem is I keep forgetting this aspect :-)

I find it extremely annoying but before I file a report I want to make sure 
other folks don't consider this a "feature"

split root logical volume to var tmp home etc

[Zhengquan Zhang]

Hi, debian list,
I had a lenny installation that has the lvm setup done by the lenny
installer, I knew nothing about lvm then so it ended up with a single
root lv.

Now I would like to follow other list member's advice to have separate
LVs for var, tmp, home etc. But I don't know how to perform the
operation to make it happen, I have skimmed lvm howto but I don't see a
chapter detailing on this task.

Thanks for any pointers!

Here is my setup

FilesystemSize  Used Avail Use% Mounted on
/dev/mapper/debian-root

tmpfs1008M 0 1008M   0% /dev/shm
/dev/sda1 228M   28M  189M  13% /boot

the harddrive is 250G

there are only two LVs in root PV, the root lv is 50G and the sap lv is
4G. and the pv is 249.80G.  it has 195.80G free PEs.

Packages that could be upgraded and have been placed on hold:

aptitude search '~U~ahold'

Pakchages that could be upgraded:

aptitude search '~U'

(Assuming that, for your purposes, "could be upgraded" is equivalent to
 "have been held back".)

network-connected camera with motion-detection e-mail configurable in Linux?

[Barclay, Daniel]

Does anyone know if there any wireless network-connected video cameras
with in-camera motion-detection-triggered e-mail notification that are
configurable via Linux?


The cameras I've seen need to have the wireless network configuration
set up while connected via a cable, and come with a Windows-only
program to perform that setup.

Is that setup typically done with a proprietary protocol, or does the
setup program probably use something standard like SNMP?


For one camera I saw, other than the wireless-network setup, the
camera could be configured via a wen browser.  Well, mostly--the
motion-detection windows can be configured only using Internet
Explorer.  (Even though they already used Java for some things,
they didn't use the cross-platform Java for that window configuraion,
and apparently used an ActiveX control.)



Thanks,
Daniel

Thanks very much.  I swear I read the docs, but I guess I
can't read.

For my purposes I think I want:

aptitude search '~U' -o  
Dir::Etc::sourcelist=/etc/apt/sources.list.securityonly


where sources.list.securityonly has just the security.debian.org
repositories.  (It makes me wonder if there's a way
to do this without having a separate sources.list file.)

Hello,

Last-point first, you can instruct Debian-Installer to prompt for fixed
IP (rather than using DHCP).

You need to pass this argument at boot prompt:
  netcfg/disable_dhcp=true 

(read http://www.debian.org/releases/lenny/i386/ch05s03 )

Typically you'd do motion detection with the zoneminder

Sorry, missed the wireless part.

I'd guess that for wireless support you'd want to stick
a 10349 interface board on and plug in a usb wireless device.
Or maybe there's other options.

YMMV.

You seem to have missed a key part of my question.  I was asking about
network-connected cameras--ones that do not require a host computer
(other than the computer "hosting" the browser) for viewing and,
hopefully, configuration and initial setup.

Re: split root logical volume to var tmp home etc

That because it has nothing is particular to do with LVM.  It is just like 
splitting / into multiple partitions or across multiple disks:

(0. [LVM specific] Create the new logical volume(s).)
1. Create new file system(s) on the block devices. [LVM: logical volumes]
2. Remount the original file system read-only.
3. Mount the new file system somewhere temporary.
4. Copy the data across.
5. Unmount the new file system.
6. Mount the new file system in it's permanent location.
7. Remount the old file system read-write.
8. Update /etc/fstab.
(Here you may want to reboot to make sure the system will do so without 
manual intervention, to make sure your changes to the fstab are correct, and 
to make sure any of the files that have been moved the the new file system 
are no longer open on the old file system.)

9. Bind mount the old file system somewhere temporary.
10. Remove the data from the old file system via the bind mount.
11. Un- bind mount the old file system.

Example: splitting / into / and /var:
0. lvcreate -L 8G -n var debian
1. mkfs.ext3 /dev/debian/var
2. mount -o remount,ro /
(The above command probably won't work because some things are constantly 
writing to [e.g.] /var/log.  You might try something like: fuser -mk / && 
mount -o remount,ro /.  Or, you might just work from a system rescue disk.)
3. mount /dev/debian/var /mnt
4. rsync -HaAxX --progress --stats /. /mnt/.
5. umount /mnt
6. mount /dev/debian/var /var
7. mount -o remount,rw /
8. echo '/dev/debian/var/varext3relatime,acl0   2' >> 
/etc/fstab
(If you want: /sbin/shutdown -r now -t 5.)
9. mount -o bind / /mnt
(Okay, so now /etc/fstab and /mnt/etc/fstab are the same file.  However, 
/var/log/messages is on the new filesystem and /mnt/var/log/messages is on 
the old file system.)
10. rm -rf /mnt/* /mnt/.[!.]*
11. umount /mnt

Chris means PV, not PE.  (PE is a physical extent, the minimum unit of 
allocation to a volume by LVM; I forget the default size.  Each LE maps to 
exactly one PE.)

Their partition table would look like:
hda11G  ext3
hda2(rest of disk)  Linux LVM

They would have one physical volume output by pvs.

I don't think I missed that part.  The Elphel will, e.g., stream
ogg theora video viewable in, e.g., mplayer.  (With high resolution
and high frame rates too.)  Or do you mean that
the camera must have a video display attached?

Not that I see.  The security repositories have a different label (l=Debian-
Security) than the main repositories (l=Debian), but I don't see an aptitude 
search term that will let you filter based on the label.

You could do some pinning based on the label and then use aptitude to search 
for packages of a certain priority, but that seems a dubious fix.

Anyway, the camera itself runs Linux, and yes, has a web page
via which you configure it.  As far as the motion detection and
email sending, you might have to compile that yourself.  (Perhaps
ask on their mailing list or something.)  And I don't know whether
it would run zoneminder at the desired framerate, etc., or if
some simpler motion detection would be good enough.

Their cameras are not cheap and the lenses can be expensive too.
But the resolution, framerate, low light, etc. specs all looked
really good.

At this point we're probably offtopic and I've exhausted my knowledge
anyhow so I'll stop.  I just thought I'd point you in that direction.

Yes.  Maybe it's supposed to look like that?  Or maybe it's because
I'm still using the etch iceweasel?

the prerm-script is usually autogenerated and consists of an automatic part
and a manual part, which is executed if not all requirements are met for the
automatic part.
this is checked by a simple if-query.
you have to remove the if-query, the automatic part and the closing endif to
ensure a clean uninstall. just writing "exit 0" at the top would work, too,
but might leave some litter on your system.

As an aside, I use the "It's all text" firefox plugin to let me fire up
the editor of my choice (gvim, in my case) for any web text box.

Then I'd use the editors features to format it. I can't remember how to
do the line wrapping stuff in vim, but

:s/^/> /

should work for the quoting, as with the sed example someone else gave.

It is a long read.  I've read it a few times and there
is still lots I don't understand.  For example, I never
really understood the --force switch in the create
context.  I think I get it now.

Nevertheless, this doesn't seem to be the behaviour I 
remember from an Etch system.  I have to say though
that I was plagued with h/w problems on that (now trashed)
system, so I don't know what normal behaviour looks
like.  I'm now having another stab at mdadm with a
new mobo and a new DIMM.  

I'm still certain of the ide expansion cards though.  I've
been putting them in the machine one at a time.  I was 
alarmed when I saw two spares because it seems to me
that on the last system I saw one spare and all the rest 
resyncing.  I want to be sure of the system before I add
another ide daughter card.  So, I'll give it a little 
more time and see if the extra spare doesn't get
integrated into the array.

thanks,

Re: network-connected camera with motion-detection e-mail configurable in Linux?

[Bob Weber]

I have a Intellinet 550710 (about $200) camera which is configurable via 
a web page.  Network connection is wired and I use a Linksys Powerline 
(plts200) network extender since the building I use the camera in is 
over 200ft away and is metal (a barn).  It has motion detection built in 
via xfer to a ftp server.  I run only linux and this was easy to setup 
via a web browser (Firefox) and ftp server.

The cameras I've seen need to have the wireless network configuration
set up while connected via a cable, and come with a Windows-only
program to perform that setup.

Is that setup typically done with a proprietary protocol, or does the
setup program probably use something standard like SNMP?


For one camera I saw, other than the wireless-network setup, the
camera could be configured via a wen browser.  Well, mostly--the
motion-detection windows can be configured only using Internet
Explorer.  (Even though they already used Java for some things,
they didn't use the cross-platform Java for that window configuraion,
and apparently used an ActiveX control.)

Yes, Etch is still available (use etch or oldstable in your
sources.list). If you upgrade from Sarge to Etch, then from that to
Lenny, make sure you read up the relevant release notes (first Etch's,
then after you've upgraded, Lenny's). Also read up on the relevant
erratas, too. It should be fine doing it in stages, but make sure you
read up first so that your transition is as smooth as it can be.

take a look here http://wiki.debian.org/DebianEtch  as far as i know
etch should be supported for a year after lenny was released.  i just
updated my etch server a couple weeks ago with no problems.

awk '{print "> " $0}' filename

or just type:

awk '{print "> " $0}' 

paste some text into the buffer, and hit ctrl-D when you're done. It'll
return the quoted text which you can paste into your webpage.

This syntax might be a bit easier to remember than the sed command
Kumar gave. Plus you can add the fmt command he mentioned to reformat
your text to a certain width if you choose.

Yes, but I think to remember that you can't completly do it "as is" since even 
on the expert mode you are not allowed to choose repos for security updates 
(nor you can choose to install without security updates).  The net result is 
that security updates always go to the Internet.


But you could pass at boot time a boot param pointing to a D-I template which 
in turn overwrites all repos to point to your apt-proxy.  I do it and go a 
step beyond that: I use a TFTP/DHCP/PXE server which feeds the netinst images 
and the URL to the template so I can automate most of the install process.  
You'll find step-by-step tutorial to achieve that on the Internet.


  
or is it better to put in a proxy server and 
do the initial install that way?



A "generalistic" web proxy server properly configured should do the trick 
since it would happily cache your security updated packages too.  The netinst 
offers you to configure going through a proxy at least when on expert mode.



  
Jesús thanks for your input.  I hadn't thought about using expert mode. 
But I had downloaded the 5.0.1 netinst disc. 
So, today I tried expert mode.  To my surprise it asked if I wanted to 
include security and volatile.  I said no.  The install went through 
apt-proxy great.  When I was done I copied the sources.list from another 
computer over and everything seems right. 
Thanks for your help.

sed/awk/fmt question hijacked from Re: Program for quoting text like in email?

I've been learning to use sed and awk and grep, etc., lately.
I have a general question (probably more appropriate elsewhere, but I'm 
going to ask here anyway.  Smack me later.).


Why is it that with sed, stuff like
sed -e /searchterm/d
I have to do
sed -e /searchterm/d infile > outfile,
and can't just do sed -e /searchterm/d file, without having to generate 
another file?

If I just do sed -e /searchterm/d file
I get output to the terminal, but no change to file.
Likewise, I have to the same with grep
like
grep -v "^$" filename > newfilename
I can't just to grep -v "^$" filename
and have grep do its magic on filename, without generating a second 
output file.
(I used both of these today to manipulate a script to remove duplicate 
files on my system, which I found at 
http://elonen.iki.fi/code/misc-notes/remove-duplicate-files/ this 
generated a script that listed all duplicate files with rm at each line, 
then used sed to remove certain lines from that script, to preserve 
certain files, used grep to remove the empty lines...just to look nicer).

It seems fmt does the same, and, I believe awk, as well.

As such, while manipulating my script today, I kept having to do stuff like
sed -e "/.gconf/d" script > script2
mv script2 script
rm script2
sed -e "/.java/d" script > script2
mv script2 script
rm script2

I was trying to use sed to manipulate the script rather than just open 
it in a text editor and edit it by hand, but, in the long run, it didn't 
come out much more efficient...

I suppose had I done

sed -e "/.gconf/d" script > script0
sed -e "/.java/d" script0 > script1
sed -e "/.adobe/d" script1 > script2
sed -e "/docs\/.evilplans\/todo/d" script2 > script3
(etc.)
sed -e "/finalsearchterm/d" script25 > MyFinalScript
rm script*

maybe I could have further automated this, but, it just seems that if 
sed would work on a target file, without have to be ">"ed to an output 
file, that it would be more efficient.  I mean, in the above case, I end 
up with 25 scripts before I'm done manipulating the text.
I feel like I must be missing something really essential here, because I 
imagine this could be done more efficiently.
Sorry if this is the wrong place to ask, but I'm just really an infant 
with bash scripting, eager to learn, and following some of these threads 
has been enlightening.


be well,
tony

Try sed's -i option for in-place edits -- for appropriate versions of
sed.

(see `man sed`)

  You have to put a range in there or it'll only hit the current line:

:0,$s/^/> /

Hi Jan,

no, it didn't find this out on my own ;) 
It found it on the sidux board: http://sidux.com/PNphpBB2-viewtopic-t-16472.html
Glad that it works for you.

True. I usually use visual mode - shift-v and cursors (or G to jump to
the bottom, in this case) to select the lines, then I only type what I
did above, and it sticks in the range automatically.

GNU sed (which is what you are most likely running) has the -i option to
make the changes in the source file.

sed -i -e /searchterm/d inoutfile

You cannot do the same with grep, since grep is usually used to print
out pattern matches. You would not normally want to kill the file you
are grepping.

In your specific case, you can use sed:

sed -i -e "/^$/d" filename

>As such, while manipulating my script today, I kept having to do stuff like
>sed -e "/.gconf/d" script > script2
>mv script2 script
>rm script2
>sed -e "/.java/d" script > script2
>mv script2 script
>rm script2

You can combine these into a single sed invocation:

set -i -e "/.gconf/d" -e "/.java/d" script

mailto: links mutt - iceweasel

[Tony Baldwin]

Hi.

I found this:
http://www.linuxquestions.org/questions/linux-software-2/firefox-mutt-and-mailto-links-272743/#post3567184
for getting firefox to play with mutt for handling of mailto: links.
But I can't find any reference to "mailto: " in about:config in iceweasel.

Can iceweasel be made to play with mutt, or am I barking up the wrong browser?

thanks
tony

Because, just like Firefox et al, it's not there by default, you have to
create it.

See http://howto-pages.org/mozilla.php for an excellent how to.

Bandwidth shaping

[Francesco Mazzoli]

I run a little server, and I'd like to know if it is possible to give
more bandwidth"priority" to certain process.
With priority I mean that the one with the higher priority won't be
limited in anyway, while the one with the lower will "adapt" to the traffic
of the other.

Thanks a lot.

Not pppconfig.  For a DSL modem configured as a bridge (most default to
router these days) he would need to run pppoeconf but I don't think that
any cable providers use PPPoE.

No luck for me! Tried pppconfig but it could not recognize the modem.

Is it that the modem is not 'installed'?

Also, the same modem works without any username and password on another windows 
machine after connecting it on the LAN port.

Thanks in advance for your help.

Hi,

At the risk of telling the obvious, Debian releases with 2.4 kernel
(Sarge?) aren't supported anymore.

Connecting such machine to the internet is, well... insecure.

Debian Lenny has two 'light' desktop (XFCE and LXDE) that should be
suitable for older machine.

While in parlance you can call it modem technically it is a modem only
if connecting through serial port. If it is connecting through network
cable it is a network device and your problem would be more in area of
setting up IP and ranges.

Clarify.
