KDE - reset of graphics?

[Hans]

Hi folks, 

from time to time I get the message from KDE, that the "effects are  started 
new, due to the reset of graphics".

Doies someone watch this effect, too? It is not often (about 2-4 times a week).

Although it does not harm much, I would like to know, if this is seen 
by.someone else, too, or if it might be just an unlucky combinaton of my hard- 
and software.

I am running nvdia proprietrary driver, my card is a GeForce 8600GS. The 
driver is version 340.96-9. You know, this is the one with the "konsole"-bug.

Thanks for feedback!

Best 

Hans

I haven't seen it recently, but yes.  It happened most often when
various KDE part were upgraded (I run testing), but not all.  As a
result, some parts of KDE were v4 and others were at v5.  Things have
been okay for a while now.

But if you want to restart a running daemon, that action does *not*
depend on the boot configuration at all: it should be restarted if
running, but not started if it was not running before.  invoke-rc.d
doesn't help in this case.

Well, the default for packages using debhelper has recently changed:

+---
| v10 This compatibility level is open for beta testing; changes may
| occur.
|
| Changes from v9 are:
| [...]
| - The dh_installinit command now defaults to --restart-after-upgrade.
|   For packages needing the previous behaviour, please use
|   --no-restart-after-upgrade.
+---[ man:debhelper(5) ]

So the default assumption for Debian is to expect this to work.

Changing the configuration and only then restarting the service also
matches what happens with most configuration changes besides packages
upgrades in my experience (either manual changes or changes applied by a
configuration management system).

Re: invoke-rc.d

André Majorel:
Do you think the following would work on any Debian system, regardless 
of its current run level and choice of init system ?


1. run invoke-rc.d daemon-package stop
2. update config file
3. run invoke-rc.d daemon-package start 


Don't use invoke-rc.d yourself.  The *old pre-systemd* Debian Policy 
Manual vaguely and indirectly warns against it; my proposed revised 
systemd-aware Debian Policy Manual explicitly warns against it, based 
upon discussions during the Debian systemd Hoo-Hah; the manual page for 
my invoke-rc.d shim warns against it; even the Debian/Ubuntu manual page 
indirectly explains what it is not for. It is for a very particular 
need.  It is not for general service management tasks by a system 
administrator.  Use the "service" command.

Don't use "stop" followed by "start" to enact a conditional restart 
after reconfiguration.  That unilaterally starts services if they 
weren't already running.  Use a single invocation with the verb 
"force-reload".  You can often also use "try-restart", or 
"condrestart".  The latter two are better, as a matter of fact, because 
Fedora defines "force-reload" differently to the LSB.  In the Fedora 
world, "force-reload" is supposed to actually start a service if it 
isn't currently running.

My shims are not the only places where verb translation happens. You 
have to do it, too, if you move between "invoke-rc.d"/"service" and 
other things.  systemd's own systemctl utility is not the same as the 
"service" command, for one thing.  It does not provide the LSB verb set, 
but a revised verb set of its own; one that has changed with time, too.  
For it, the (currently) correct verb here is "try-reload-or-restart", 
which attempts a reload, and if that is not possible does a restart, but 
only if the service is currently already running.  "condrestart" used to 
be available and documented as an alias for (what was then) the 
"reload-or-try-restart" verb, and later became an alias for the 
"try-restart" verb.  It has since been removed from the systemctl 
documentation altogether.  I haven't checked whether it is still 
actually there in the program.

So, client1 can go to 192.168.1.0/24 but can't see other clients in

IMO, your best bet is to physically isolate the networks. 192.168.1.0/24 
clients are on one switch, and 192.168.2.0/24 clients are on another 
switch. Only a single gateway host connects the two switches, and all 
clients must route through this host to reach the other network.


If both clients are on a shared network segment, then what's to stop a 
192.168.1.0/24 client adding a 192.168.2.0/24 IP to their network 
adapter and talking directly? If you trust the hosts not to do that, 
then you could still work as above, but note that firewall rules will 
become a bit more complex (you can't assume that eth0 talks to 
192.168.1.0/24 and eth1 talks to 192.168.2.0/24, for example). It's not 
impossible, but needs a bit more care.




Any idea?

Hi all!

I'm thinking deploy a Debian backup server using Dirvish (which is based
on rsync --- indeed, we have packaged it in Debian). On previous
occasions I implemented these solutions seamlessly with GNU/Linux
clients, but now I would like add Windows clients.

The idea of using Dirvish is because I had a very good experience.
Besides using rsync with hard links for backups of files that do not
change from backup to the next allows a considerable saving of disk space.

But to use Dirvish with Windows clients I will need to install an SSH
server. I had thought that an alternative would be to use Cygwin, but
was looking for documentation and I have not found any uniform process
to install and configure a Cygwin SSH server on Windows.

I would like to know if anyone has had any experience in this regard
that could share.


Can I recommend BackupPC (also in Debian), which performs similar 
de-duplication to dirvish (hard links between identical files with 
optional compression as well), but can pull files from computers using 
rsync, ftp or, relevant to you, SMB. That is, it can backup Windows 
clients without any client software being installed on them.


Obviously, SMB will probably be slower than rsync as you'll need to pull 
every file every time, but you may find that's preferable to trying to 
get rsync installed on your Windows machines.





Thanks in advance.

Kind regards,
Daniel

Than the only thing that's left would be whitelisting all the rest of
the mac addresses using iptables (for as long as he won't try changing
the mac addr to something switched off at the time) or RADIUS
authenticated wpa-enterprise wifi network with separate
username/password. Also VLANing his port on the switch + iptables rules
for vlan (eth1.5 for excample). All of this might be even used as
challange mode forcing kid to learn new stuff as he overcomes more

I am running testing on my desktop pc (graphics onboard), my EEEPC
1005HAG (Intel I-945 chip) and the mentioned notebook. 

Mostly it happens on the notebook. Once it appeared on the EEEPC and on 
the desktop pc never. I agree to you, that it might be due to the mix
of v4 and v5. 

As I already said, it happens not often, but from time to time. 

Just wanted to know, if this happens at other users, too. 

Of course, I believe, there are only very few users, who run the
combination of debian/testing + KDE * nvidia card + proprietrary nvidia
driver.

I have the feeling, most prefer LXDE, Gnome or just the commandline.

Happy hacking!

NFS no_root_squash not working (permission denied)

[Greg Wooledge]

I am trying to backup files from one server, using another server
which has a tape drive attached.  I've done this many times before.
The problem is, *this* time, root on the NFS client can't read the files
on the NFS server.  It appears that no_root_squash is being ignored.

I have two Debian systems:

1) NFS server: svr4 (jessie)
2) NFS client: arc1 (squeeze) (has tape drive)

On the server (svr4) I have this line in /etc/exports:

/home   -no_subtree_check arc1(ro,no_root_squash,sync)

On the client I use autofs, but for purposes of demonstrating the problem
I will use manual mount commands.  (Rest assured it breaks just the same
with autofs mounts.)

arc1:~# mount -v -t nfs svr4:/home /mnt
mount.nfs: timeout set for Mon Aug  8 10:57:37 2016
mount.nfs: trying text-based options 'addr=10.76.142.85'
mount.nfs: prog 13, trying vers=3, prot=6
mount.nfs: trying 10.76.142.85 prog 13 vers 3 prot TCP port 2049
mount.nfs: prog 15, trying vers=3, prot=17
mount.nfs: trying 10.76.142.85 prog 15 vers 3 prot UDP port 58163
svr4:/home on /mnt type nfs (rw)
arc1:~# ls /mnt/wooledg/Maildir
ls: cannot open directory /mnt/wooledg/Maildir: Permission denied
arc1:~# su wooledg -c 'ls /mnt/wooledg/Maildir'
courierimapkeywords  courierimapuiddb  cur  new  tmp
arc1:~# umount /mnt

arc1:~# showmount -e svr4 | grep /home
/home  arc1.eeg.ccf.org

So, the file system mounts correctly, and the non-root user can read
the files, but root can't read them.

I have rebooted both the client and server machines.  I have tried
restarting NFS services on them, too.  I have done "exportfs -u -a" and
"exportfs -a".  I've done everything I can think of.

This is very similar to what I see in bug #492970 and this past
discussion:

https://lists.debian.org/debian-user/2008/08/msg01943.html
http://bugs.debian.org/492970

However, both of my systems are newer than the systems described in
that bug report, and I don't think "downgrade to nfs-common 1.1.2"
is a viable solution for me.

Is there any package I might be missing on the new jessie server, either
for general NFS operations, or specifically for compatibility with older
Linux NFS clients?

One final note, though I don't know how it may relate: svr4 was just
upgraded to Jessie on Friday, to replace a machine that died.  I reused
the same IP address.  The machine that died was running Jessie but with
a Wheezy kernel; it had been upgraded many times, originally installed
from Lenny IIRC.  This all worked fine on the old server.  It is not
working on the new server.  It had crossed my mind that something was
caching the old server's information due to the IP address reuse, but
I have rebooted both systems since then, so that shouldn't be the case.

ebtables could enforce that but I agree it is much more hassle than

It sounds like a blocking issue. Researching about it, I read something
about what you mention here [1]. As it says, it seems that this is
resolved in new versions of Cygwin, although you say that a week ago you
had this problem (with the latest published version?). But this article
is "a bit" old.

He also mentions a problem to doing backup over open files. Have you
experienced that problem?

It does not sound very encouraging. An alternative that I thought as a
last resort was to mount the remote filesystem on the backup server
using Samba and then to use rsync on the mount point, although I'm not
sure how efficient it can be.


Thanks for your reply.

Thanks for the recommendation. I hadn't the opportunity to use BackupPC,
but I will investigate it.

As I said in another message of this thread, I thought that an
alternative could be to mount on the Debian server the filesystem for
the Windows client using Samba and then doing rsync against the mount
point, but I'm not sure how efficient it can be. We also have security
implications as the backup server and the Windows computer are in
different offices, so the backup would be over the Internet.

For a production server, Debian is an excellent choice, however it's
probably not the easiest way into Linux.

For your particular application, which apart from Linux and Apache, will
also need MySQL and PHP, you need what is referred to as a LAMP server.

There are a number of these available as specialised distributions,
based on either Debian, SuSe or RedHat/Centos, or there is a portable
version which will run on Windows, from a USB stick if required
(USBwebserver, http://www.usbwebserver.net). Some are mentioned here,
https://en.wikipedia.org/wiki/List_of_Apache%E2%80%93MySQL%E2%80%93PHP_packages
you will need to check which versions of the components are included.

Here is a guide to making a LAMP server from Ubuntu, one of the more
popular Debian-based distributions:
https://help.ubuntu.com/community/ApacheMySQLPHP
There's a lot more on the Net about LAMP servers, much of which of
course is out of date.

If you still wish to start with Debian itself, you will find less
hand-holding. Here is the starting point:
https://www.debian.org/releases/stable/installmanual

The most efficient way is probably to start with the Netinstall image
https://www.debian.org/CD/netinst/ for your virtual machine and add what
tasks are necessary. Use the expert installation, as various important
choices are not available otherwise. Look up anything you don't
understand, or come back here.

For a server, it's probably not worth using either of the heavyweight
desktops, Gnome or KDE, and instead to choose Xfce or LXDE. After a bit
of experience, you won't bother with a graphical environment at all on a
server, but for someone moving from Windows, it's probably safer to
stay graphical for now.

What I can't tell you today is exactly what you need for a new
installation. My server has the LAMP components, but the originals were
installed years ago, and the server upgraded several times as new
versions became available, though it still isn't the current Jessie
distribution. From time to time, functions have been moved into
different packages. These are the packages I have now which seem to be
apache2, mysql and php-related:

apache2
apache2-mpm-prefork
apache2-utils
apache2.2-bin
apache2.2-common
libapache2-mod-fcgid
libapache2-mod-perl2
libapache2-mod-php5
libapache2-reload-perl
libdbd-mysql-perl
libmysqlclient16
libmysqlclient18:amd64
libqt4-sql-mysql:amd64
mysql-client-5.5
mysql-common
mysql-server
mysql-server-5.5
mysql-server-core-5.5
php5-mysql
libapache2-mod-php5
php5
php5-cli
php5-common
php5-gd
php5-imap
php5-ldap
php5-mcrypt
php5-mysql
php5-sqlite
phpmyadmin

Many of these are dependencies, and not all are probably essential to
your application. Selecting the 'web server' role during installation,
then installing 'php5' and 'mysql-server' afterwards should pull in most
of them. phpmyadmin isn't a dependency, but I find it very useful for
administering MySQL, so much so that I need to look up the actual MySQL
cli commands when I need them. I repeat, Jessie may not use exactly the
same packages as my server, which runs the Wheezy distribution, but
this should be a good guide.

Best of luck. Any problems, come back and we'll try to help.

Have you tried Putty? I know next to nothing about Windows, but I've seen Putty 
discussed like it does SSH seriously.

Dirvish, I think, is a good backup package. It creates backups that can be 
handled with plain *nix software if you lose the backup software. Like Amanda.

How to get rid of M10

I have an acer aspire XC-704G with windows 10 on it.  I changed the BIOS

Re: How to get rid of M10

Maybe using pendrive and booting his Notebook's USB port.
See what the priority boot devices must be, ensuring yourself if it's CD/DVD 
ROM to boot him.

Try some Debian-based and Ubuntu-based GNU/Linux operating systems if you can.

You possibly need to disable secure boot from bios settings.

Try F2 and change the boot order in the BIOS.

https://mans.io/files/viewer/72128/25

Watch the messages as you turn the computer on.  There may also be a boot 
menu.  In addition, you may need to change some of the settings in the BIOS, 
besides the boot order.

What I always recommend is to disable UEFI in BIOS. The option you're
looking for is LEGACY BOOT/UEFI switch. Then you'll be able to set boot
order normally and install OS. I've heard that Linux supports UEFI but
it was always really painful for me to get it working. If you plan to
use Linux exclusively than LEGACY BOOT might be the easiest way to go.

script stops responding for browsers

[Haines Brown]

I have been running both Icweweasel and Pale Moon browsers under
Wheezy. About a week ago they produced this warning:

"A script on this page may be busy, or it may have stopped
responding. You can stop the script now, open the script in the
debugger, or let the script continue".

I stopped or continued the script, and with this the browsers worked as
they should. However, I rebooted, and now not only do I get the warning,
but there's about a 50-second freeze between any action with the browsers,
making them unusable. I could not copy/paste the debug here for some
reason, but this is how it starts and ends:

require.config{
  map: {
 '*': {
 'jquery/nyt': 'foundation/lib/jquery/2.1.4',
 ...
 'queue/1' ; 'foundation/lib/queue/1.0.7'
  }
   }
})'
require(['foundation/main_includes']);

I don't have a clue about what this means.

I'm not sure if I understand your idea. I know that Putty is an SSH
client used mostly in Windows but there are also versions for GNU/Linux
(also in the Debian repositories).

In this case the idea is to initiate the connection from the Debian
server to the Windows server, to bring the files to the Debian server.
This connection would be via Internet, as both are not on the same local
network.

The idea would be to use an automatic process, with a secure connection
in the extent of the possibilities.

I had mentioned to use Dirvish because it is what I use to doing backup
with GNU/Linux clients. In this way I would have a backup homogeneous
solution, which would facilitate the maintenance.

I will try to do some tests locally with Windows 2012 and Cygwin, using
rsync + ssh. The alternative would be to use Samba to access the Windows
filesystem as if it was local to the Debian server, then doing rsync to
the mount point. But it doesn't convince me from the point of view of
security to have with Samba access through Internet. Any comment about this?


Thanks for your interest.

Daniel

For security, you can use an SSH tunnel (Cygwin openssh on the Windows
machine).


Backing up over a WAN connection is only practical if your links are
fast and there isn't much data.  The same goes for verification,
restore, and archiving jobs.  Imaging is likely to be impractical.  I'd
consider building another backup machine and deploying it on the remote LAN.
