It's an eMachines desktop which was originally supplied with Windows
7. I wiped Windows and loaded on Wheezy from a live DVD. The CPU is an
Athlon II x2 220 @ 800 MHz. The graphics (on the motherboard) is a
GeForce 6150 SE nForce 430 rev a2. Looking at the output from a 
dpkg -l there's no mention of any of the packages you list above. When
I installed Wheezy for my wife, I basically just accepted defaults, so
anything which has been loaded was loaded by the installer. 

I can send you the full output from dpkg -l if you wish, just ask.

Sorry, Hans, not a solution, just a "Me too", My wife has an eMachines
PC bought from Wal-Mart, and each time I have tried to move her from
Wheezy to Jessie, the upgrade reports no errors, you can log in and
the GUI is there, but the moment you touch the mouse the screen breaks
up into a whole series of short horizontal lines, and there is no way
out of it but to reboot. This is totally reproducible, and I've seen
exactly the same effect with a recent Linux Mint (not LMDE, the
Ubuntu-based version) live disk. 

If anyone had this problem and managed to sort it, I'd be very
grateful for the solution, because at the moment my wife's PC is stuck
at Wheezy, and cannot be upgraded. 

Thanks, 

Brian. 

replaygain, soundkonverter, aac/m4a glitch

[Seeker]

The story so far. On Debian unstable.

Easymp3gain was removed from Debian unstable. Settling in on 
alternatives before I remove it from my system.


Not completely against using the different *gain tools from the command 
line, but would prefer GUI.


Tried QTGain https://sourceforge.net/projects/qtgain/
Apparently from the change log it had more of an interface, but went 
back to minimal with the port to QT5.


Initially had a not previously gained mp3 file to test. After letting 
QTGain do it's thing, something seemed a little odd when looking with 
easymp3gain, the replaygain tool in Soundkonverter, and Musicbrainz 
Picard to see what replaygain information they showed.


After adding, removing, adding, removing with no issues, went back to 
QTGain a second time and after using QTGain the second time, Easymp3gain 
showed the volume at 89, instead of volume '92' and track tag '-3'.


So QTGain is out.

Generally speaking I'm leaning toward using the replaygain tool in 
Soundkonverter, looked good from my initial testing with mp3, ripped 3 
CDs and used it for them so it looks good with vorbis audio.


Where the glitch comes in is with m4a files. The replay gain tool just 
shows question marks in the track and album gain fields. Tried checking 
the box to force recalculation then clicked the 'Tag Untagged' button, 
looked like it was behaving correctly and doing the 
calculation/recalculation, still shows question marks. Easymp3gain shows 
the gain has been set.


Next found a different album of m4a files, loaded them in Easymp3gain to 
verify the tags were there, loaded them in the replaygain tool and again 
it just showed question marks.


I did also post a message in the KDE forum asking if anybody else has

Problems with upgrade from Wheezy to Jessie

[Hans Kraus]

Hi,

I upgraded my Debian server about a week ago from Wheezy to Jessie.
After that the GUI stopped, I see only  the grey screen with the sad
computer telling me " Oh no, Something is Wrong" and the only option is
to log out.

I'm using Gnome as my desktop. I installed the package again with:
apt-get install task-gnome-desktop
I did not get any error message, but that didn't cure my problem.

Afterwards I tried: "dpkg --configure -a". Again, I didn't get any
error message but  that didn't cure my problem.

I rebooted the system several times but with no avail.

Which info should I provide and/or where should I check my system for
errors? The text based login via ssh (I use Putty from Win 8.1)
functions without problems.

Kind regards, Hans

Difficult this. It doesn't look hardware related because X comes up and
you get what is known as the "fail whale" (and a most informative and
helpful message :) ).

Also difficult because what you had personally configured on Wheezy is
unknown. So we'll try a thing or two. No guarantees.

Disable logging in with gdm3 with

  systemctl set-default multi-user.target

You can reverse this with

  systemctl set-default graphical.target

Make sure you have xinit installed ('dpkg -l xinit') and reboot. Log in
and run 'startx'. Over to you.

This is a bit vague, so a better explanation would be good. What
exactly do you mean "gui stopped"? Did that happen during the
update? Or at boot? Does the login screen show up? Does this
message show up after login?

That means your packages are in a state that dpkg assumes to be
consistent. However, since you upgraded recently, and apparently
still have access to your shell, could you tell us what the
contents of /etc/apt/sources.list is?

Some people have computers upon which they have successfully performed
operating system in-place major version upgrades; some boast of several
such upgrades over many years.  I didn't have much success with this
early on, so I pursued the KISS approach instead.  I have invested in
learning and resources that allow me to do image, backup, archive, wipe,
install, configure, restore, migrate, test, commissioning, and cut-over
processes.


I find it helpful to:

1.  Have a dedicated hardware firewall/ router appliance.

2.  Have more than one computer, each dedicate to one purpose:

a.  File server.

b.  Backup, archive, and imaging.

c.  Workstation or laptop (one user each).

d.  Other, as needed.

3.  Use HDD/SSD mobile racks.

4.  Maintain a supply of spare parts, including a spare computer that
can substitute for any of #2.


It sounds like you have put yourself into a disaster recovery situation.
 I'd advise restoring the Wheezy server, building a fresh Jessie server,
migrating the services and data, testing thoroughly, and making a decision.

More information.

Found some m4a files that did not have replaygain tags.

Clicking 'tag untagged' then checking at the command line

aacgain -s c *

showed no replaygain data

returning to the replaygain tool, checking the box to for recalculation,
then clicking 'tag untagged'

aacgain -s c *

shows replaygain data.

I am running stable 8.5 on my backup machine.  It is a 386 install.  Backuppc is
version backuppc/stable,now 3.3.0-2 i386 [installed]

It uses apache2 (dont know if it will use other web servers) and has put the
following in the apache  /etc/apache2/conf-enabled/backuppc.conf file:

Alias /backuppc /usr/share/backuppc/cgi-bin/


AllowOverride None
Allow from all

# Uncomment the line below to ensure that nobody can sniff importanti
# info from network traffic during editing of the BackupPC config or
# when browsing/restoring backups.
# Requires that you have your webserver set up for SSL (https) access.
#SSLRequireSSL

Options ExecCGI FollowSymlinks
AddHandler cgi-script .cgi
DirectoryIndex index.cgi

AuthUserFile /etc/backuppc/htpasswd
AuthType basic
AuthName "BackupPC admin"
require valid-user



So I would assume that there should be a working install of apache2 before
backuppc is installed.  The only install problem I remember (this was quite a
while ago) was that I wanted the backups put in a directory mounted on a
separate partition.  Even though there was a setting for the backup directory in
backuppc the directory is hard coded to  "/var/lib/backuppc" in some of the
installed backuppc programs.  So to use another location you have to symbolic
link /var/lib/backuppc to that directory before install (or mount the partition
on /var/lib/backuppc).  So if you want to use another directory delete
/var/lib/backuppc and make the link (link -s /var/lib/backuppc  /somewhere-else
  ormount /dev/sdxx /var/lib/backuppc).  Then run "apt-get install
--reinstall backuppc" and hopefully things will be setup correctly at that new
location.  Since I access the backup server on my local net I don't use https. 

I use rsync over ssh to connect to linux servers so the data transferred is over
a secure tunnel. So my backup of a remote vm is secure.  The backuppc user
should have public key that is placed in the authorized_keys file of the clients
that are to be backed up. http://backuppc.sourceforge.net/faq/ssh.html explains
this procedure.

Hope this helps.  I have run backuppc over 10 years at several locations where I
have worked and at home.  It just seems to run.

1. Update the computer's BIOS/UEFI (check the "support" area of the

   Debian's install media CANNOT tolerate very outdated firmware on

2. Ensure you are using a good install image from Debian 8.5 or 8.6.
   Download a new install image from http://cdimage.debian.org and

3. After the BIOS/UEFI update, try the install again with a known-good
   install media for Debian 8.5 or 8.6, and if the crash still hapens,
   give us a lot more detail of what exactly is happening.  Start with

Olá,


Faça o tcpdump sem colocar as opções de origem e destino, conforme abaixo:


tcpdump -n net 192.168.3.0/24 and net 
192.168.2.0/24

Correto Benedito, mas a resposta q a origem envia ao destino deveria ser 
apresentada.
Digo, se eu faço um ping para o ip da rede 
192.168.2.0/24 para um ip da rede 
192.168.3.0/24 o host da rede 192.168.2.0 tem que 
responder, e esse pacote de resposta eu não consigo capturar no tcpdump, 
acredito que seja um erro no output do software para o stdout do linux...
é uma hipotese.

Re: Mutt and monthly delete old messages

If you prefer a mutt-only solution (without archivemail) you could also
use a hook to mark all mails older than 30 days for deletion whenever
you open the corresponding mailbox.

Untested, adapt "debian" to match your mailbox name:

folder-hook =debian  'push  " ~d>30d\n"'

Mutt will then mark older messages for deletion when you enter the
mailbox and ask for confirmation when you quit mutt, change to a
different mailbox or press '$'.

It's an eMachines desktop which was originally supplied with Windows
7. I wiped Windows and loaded on Wheezy from a live DVD. The CPU is an
Athlon II x2 220 @ 800 MHz. The graphics (on the motherboard) is a
GeForce 6150 SE nForce 430 rev a2.


This has been a problematic gfxchip for more than one user over the years. 
Try adding this to the kernel cmdline:


nouveau.config=NvMSI=0

I have a machine with the same gfxchip on its motherboard,
https://us.msi.com/Motherboard/K9N6PGM2V.html
but currently it doesn't have any Debian installed on it to check which if 
any releases are helped by it. It does have openSUSE 13.1 (kernel 3.12, 
server 1.14.3), 13.2 (kernel 3.16, server 1.16.1), 42.1 (kernel 4.1, server 
1.17.2) and Tumbleweed (kernel 4.7.4, server 1.18.4) installed. All four 
suffer random brief video corruption running X. Tumbleweed seems to have 
almost eliminated the corruption that is excessive and unacceptable in the 
others. IIRC, last Debian tried on it was Wheezy with Gnome or Mate or 
Cinnamon, and too much trouble or impossible at that time to actually use X.


Something else to try is ensuring xserver-xorg-video-modesetting is 
installed, then purging xserver-xorg-video-nouveau and all traces of NVidia's 
proprietary driver bits. The modesetting driver has been getting quite some 
attention from the devs:

http://www.phoronix.com/scan.php?page=news_item=Ubuntu-Debian-Abandon-Intel-DDX

The original owner of this motherboard suffered to the extent he installed a 
PCI gfxcard as a workaround when the motherboard was rather young. I got the 
motherboard free when when he bought a new one that I installed after its 
original RAM went bad.



Looking at the output from a
dpkg -l there's no mention of any of the packages you list above. When
I installed Wheezy for my wife, I basically just accepted defaults, so
anything which has been loaded was loaded by the installer.



I can send you the full output from dpkg -l if you wish, just ask.

If it *must* survive, 3-2-1 is the way to go.

3 copies (Original, Backup, and Backup of the Backup)
2 different media types (such as HDD(Orig) + HDD(Bk1) + Optical(Bk2))
1 stored offsite


Except for the offsite storage (Just for my private data) this sounds 
perfect for my needs. Good thing is that i have two free HDD's here with 
2TB each, so this would work ;)



That being said, most of my stuff isn't of the "absolutely must survive"
nature, so I just have it on external HDDs.  If something is
particularly important, it's on HDDs and also somewhere like google
drive / dropbox (although, encrypted when at those places).


I currently use dropbox myself to store my conf files (gzipped and then 
encrypted with aes) in case something bad should ever happen to my NAS, 
so that i can at least restore my servers quickly ;)


One question Dan: What do u use to encrypt your files? also openssl?

I had the same problem with the keyboard on the sleeve of a hybrid
laptop/tablet, and I wrote the following program:

http://nsup.org/~george/comp/misc/xi2watch.c

It watches for XInput 2 events and executes a given command with the events

Re: [Q] hostname change: i tried for 83 days. But failed. HELP ME PLEASE !!!

[Fabrizio Carrai]

Felix is right, indeed here ".chromebook" would indicates the DOMAIN and
not the name of the HOST.
But if you don't expect to use the chromebook in a network with a managed
domain, maybe you will not have particular problem. Indeed I never thought
to use a "." with the hostname command...

Byung-Hee, if you want to sleep quite and for you it is not very important
I would suggest to use "alex-chromebook" or any other name with no dot in.

Happy to have helped you

Video issues with Intel GMA X3500

[Rainer Dorsch]

Hi,

since a few weeks, I see issues on my Intel G35 chipset which includes an Intel 
GMA X3500 and Jessie. It might be a regression of a recent security update, 
since I am not aware of any changes on the system which could have this kind of 
impact (and an imagemagick security update caused an unrelated regression 
recently on my system)

I see firefox sometimes crashing, vlc has issues and even glxgears crashes 
(though this seems to be account specific).

I think these are all i965 issues:

Xfce: Apply keyboard settings on USB plug

[Florian Weimer]

I'm using the Xfce desktop environment on Debian jessie.  The keyboard
is plugged into a KVM switch which issues a USB disconnect if I switch
to another machine.  Once I switch back, the USB connection comes back
again, but the keyboard settings are gone.  This affects both the
changes in keyboard repeat/delay I configured within Xfce, and the
modmap I set with Xmodmap on session start.

Is there are simple solution to restore the keyboard settings, one
which is less hackish than watching for USB-related messages in dmesg?

Thanks for the very nice and long explanation Mark! :)

I think i should elaborate a little more on my setup.. i guess i did not
make that very clear in the first place, sorry about that.

My network is consisting of the following systems:

Main PC - 192.168.23.11  (Running Debian Jessie)
Server  - 192.168.23.200 (Running Debian Jessie)

The server is always online, the PC is only half of the day on.

What i want to do now is the following:

Sending mail from my Main PC to my Server and also the other way around,

>from the Server to my Main PC.

The Server should also be able to send mail to the "outside" (Meaning to
other SMTP servers).
The second requirement is optional since i dont own a domain and all
this is sitting locally at my home. The most important thing for me is
to send and receive mail from both systems in my home network.
I hope this made my problem a little clearer :)

I'm a little ashamed to say that, but i could not totally follow your
explanations Mark... I'm quite a newbie when it comes to SMTP.. sorry :(

Thanks again for all your help ;)

I should have been a little clearer myself. You don't need to register a
domain name. Just invent your own domain name for local purposes. Let's
say you choose the domain name "monet", and that you have already given
the hostnames "desktop" and "server" to your two machines. Then you
would edit the file /etc/hosts on both machines to contain the following
lines:

192.168.23.11 desktop.monet desktop
192.168.23.200 server.monet server


I did that on gnome and desktop with appropriate changes:

   192.168.7.20 desktop.monet desktop
   192.168.7.67 gnome.monet gnome


Now you only need to tell exim4 on the server that it is the final
destination for emails to *.monet, again using the debconf wizard. You
will then be able to send emails to local addresses, while emails to all
other domains will go through your ISP's smarthost.


I did that on gnome and desktop.


Incidently, you can also tell exim4 on the desktop to use the server as
its smarthost.

I realise that you're getting lots of (sometimes contradictory)
information from various sources. The barebones configuration I have
described above has served me well for several years.


All commands are issued from gnome.

 brian@gnome:~# ping -c3 desktop

We expect that result because ping uses files in /etc/nsswitch.

Am I the only one who gets this? No capability to deliver mail to
desktop. What am I doing wrong?



I think this is the problem with exim calling DNS on the given hostname...
which is doomed to fail. To get it working you need to create the
hubbed_hosts file and set your aliases in there, for example:
192.168.7.20: desktop

Then it should work fine, at least for me it did.

Hope this helps :)


Not really, I'm afraid.

We all know a hubbed_hosts file works. Mark Fletcher has written
extensively about it and I have said a thing or too also. What I want to
know is why following the advice from Liam O'Toole doesn't work for me,
even though I have followed the instructions exactly.

BTW: It would be 'desktop: 192.168.7.20' and 'desktop.monet:192.168.7.20'
in hubbed_hosts.


Ah yeah, right, i mixed the syntax up, sorry about that.

Like I said backuppc uses incremental and full backups.  The web

I currently keep 12 weekly, 8 bi-weekly and 4 monthly full backups so
that covers almost a year.


That would serve my needs well also :) (For the moment it is just my

Thanks for the info ;)


There is another solution you might like called rsnapshot.  I use it to
backup just my root directory on my desktop before I do updates.  That
way if something goes wrong I can boot into a rescue cd and restore the
system to the state before the update.  I just can't afford to have my
desktop to break.  rsnapshot uses rsync so it can backup any computer
that has rsync.  It uses hard links so duplicate files are only stored
once.  You specify how many backups you want to keep and rsnapshot
deletes older ones over that max before adding the new one.  That way
you always have backups (assuming you set the count greater that 1) that
will be there even if there is a transfer error.  This is similar to
your script but is very versatile.


I heard about it but never used it so far, i should give that a try for 
sure :)

Hello, Debian people!



I love my Chromebook. Via Crouton, i did install Ubuntu ( the internal
is Debian Wheezy, i guess).

VERSION_ID="12.04"



(precise)soyeomul@localhost:/etc$ cat debian_version
wheezy/sid
(precise)soyeomul@localhost:/etc$



By the way i cannot change hostname, i tried with followed link
[http://askubuntu.com/questions/9540/how-do-i-change-the-computer-name].



By sudo command, i edited /etc/hostname to "alex.chromebook". And i did
reboot[`/sbin/reboot']. But there is no change. Always the hostname is
"localhost".



Any comments Welcome!!! because i am going to be crazy T.T



I Want To "alex.chromebook" as hostname.


That's illegal. From http://www.rfc-base.org/txt/rfc-952.txt :

   1. A "name" (Net, Host, Gateway, or Domain name) is a text string up
   to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus
   sign (-), and period (.).  Note that periods are only allowed when
   they serve to delimit components of "domain style names".

Yeah, I don't have a spare copy offsite either -- but I don't
(currently) have any electronic data that would be absolutely
devastating if I lost it.  If / when I have kids or something, then baby
pics among other things will likely have that status.

My setup is more or less as you describe. The only difference is that
all machines are mail capable and use the local server as their
smarthost, while the server in turn uses an external smarthost.

Brian seems to be experiencing a more fundamental issue, where exim
refuses to resolve domain names in the expected manner. That one has me
stumped.

This is what I cannot get round. I'm prepared to accept that my
understanding may be defective but when I see "driver = dnslookup" in
router/200_exim4-config_primary it fits what I observe. Which is why I
use a hubbed_hosts file to manually route mail to machines on the LAN.

I have the same setup and all customisations (apart from hubbed_hosts)
have been done via debconf. TBH, I cannot see why /etc/hosts should be
consulted because I thought there is first a check for an MX record and
then an attempt to resolve the host *using the DNS* if there was none.

Your instructions are clear so I can continue to try more customising
via debconf.

mo appears to have had no more success than I have. Don't know about

The hostname command is both a query tool, and a name setter.  "man 
hostname" is your friend.  You'll probably be asked for your passwd, or 
need to become root somehow. On the *buntu's try sudo hostname.

If it *must* survive, 3-2-1 is the way to go.

3 copies (Original, Backup, and Backup of the Backup)

I am not the op, but backuppc sounded pretty nice, so yesterday I tried to 
install it on both my Wheezy and Jessie systems.  It didn't work (with 
different failures) on either system--I won't give much detail for now, but I'd 
just ask a few questions:

   * what system (what version of Debian) are you using?

   * should I expect that it will properly configure a web server (on the 
Wheezy system it talked about apache2, iirc), or must I have a properly 
configured web server before installing backuppc?

Some cryptic notes on the failures:

On wheezy, I thought the installation completed successfully--it ran something 
it called a script, and, in or after the script it gave me a url to log in to 
manage backuppc along with a username and password.  When I tried to go to 
that URL, using either http or https on either of my browsers, it gave me a 
404 error.

On jessie, it apparently did not complete the installation, it told me it 
could not run that initial script.

Suggestions?

Uuh, Mark, here on an up to date wheezy install, with exim4's default 
config untouched, it does indeed exist, as /etc/exim4/conf.d, and its 
populated with quite a few subdirs.
=
gene@coyote:~$ ls -l /etc/exim4/conf.d
total 28
drwxr-xr-x 2 root root 4096 Apr  4 21:35 acl
drwxr-xr-x 2 root root 4096 Apr  4 21:35 auth
drwxr-xr-x 2 root root 4096 Apr  4 21:35 main
drwxr-xr-x 2 root root 4096 Apr  4 21:35 retry
drwxr-xr-x 2 root root 4096 Apr  4 21:35 rewrite
drwxr-xr-x 2 root root 4096 Apr  4 21:35 router
drwxr-xr-x 2 root root 4096 Apr  4 21:35 transport
==
Based on the dates, I have to assume exim4 was pulled in as a dependency 
of something else I installed recently since this wheezy install is 
around 2 years old now. It's installation did not effect how my machine 
runs that I am aware of. According to htop, no daemon of that name is 
currently running.

It shouldn't make any difference whether the split configuration is used
or not for what we are doing.

A defaults-accepting installation would use "local delivery only; not on
a network". Obviously this would not suit testing mail delivery to other
machines on the LAN. It was at this first page I made my mistake!

I chose "Internet site.." because that is the way I always send
mail. No wonder I got "Unrouteable address". Was it clear that I should
have used "mail sent by smarthost.." (Liam?)?. Mystery solved. I've
not tested extensively but I can get mail to go to a user on another
machine.

I'm not enamoured of this technique because it does not suit my mail
setup. So I will stick with the more versatile hubbed_hosts.

Thanks for all the clues.
