Debian :: Ssh Session Freeze After Any Command?
May 26, 2010
I have debian squeeze server at work, acting as gateway, and home computer with debian sid (amd64). OpenVPN is working on server ecure connections from internet. So my home computer is connected to work server via openvpn almost 24/7. Some days ago i faced strange problem - when i make ssh session from home to work, via openvpn connection, i can login to work server, but after any command on remote console i have blank screen and nothing happening on it. Only exit is pressing Enter ~ . In server's auth log are messages about session opening and closing only.When i ssh to server from local network at workplace - via putty or native ssh - it works without any problems. I can do anything.But from home I can only login.

I have been using vim for years without problem but today I have met one weird scenario which I can't solve it after troubleshoot for the whole day and google around. This happen to my 2 machine at home which both installed with Slackware 13.1..I just got my laptop done setup with Slackware 13.1 and I ssh from my laptop to my desktop that have vim installed. I use one of my laptop virtual console to do the ssh login to that desktop.
And using vim in that laptop virtual console and Konsole itself, all works fine. The problem only occur when I ssh into the desktop using a virtual console.It seems like if I supply the vim specifically a .vimrc, it will work fine. It seems like it's taking forever to find the .vimrc file. But if I remove that .vimrc, it will also freeze. If I create a new user in that desktop and ssh again and then do vim, it will also freeze.Any one face this strange problem before ? I know I can still use Konsole to ssh and do vim, but I wish to solve this and since vim is been there for so long, I think this problem will most likely faced by someone before.

After locking my GUI session, if I type my password incorrectly when I come to unlock it, the system often (not always) seems to hang for a long time, with the text "Checking..." displayed. The length of time can be many minutes.The system is not actually frozen - if I hit CTL+ALT+F6 I can log on to a console session, from which I can see a tty7 process (i.e. the GUI session) using the 'ps' command. Sometimes the only way I can recover is to kill this process, upon which a new GUI session starts up, but this is undesirable as I lose any open applications.

I'm trying to make and make install a driver for my wireless, every time, though, I use the make command, it'll start at 0 and cound almost up to 200,000 and then the computer freezes. I've tried different drivers, same result. I've tried ndiswrapper but that didn't work either.

is it possible to execute command and terminate session all in one phrase
something like this connect to server hostname and than execute command "ls" and than some command
ssh username"at"hostname ls "something"
without "something" this phrase connects to server and lists directory, I need something that after listing directory, terminates session.

Is possible (by root of course) to run a command from console, that will be executed on X-session owned by another user on the same linux box/machine ? Example: Can root open xclock for another local user logged into X11 ?

I recently borked my video driver with a series of upgrades and found my system booting to the TTY with no access to the desktop, graphical login, or even X. I spent some days troubleshooting the problem and experimenting with possible fixes. I found myself wishing for some way to copy and paste from the TTY, or at least log all input and output to a file.
Code:
# bash 2>&1 | tee /tty-session.log

I had chosen automatic logon. Then updated to 10.04. During logout to change Desktop Environment/Session, I noticed that GDM login screen had an option for KDE session although I had not installed KDE. I got curious. So I tried it. System hangs. Restart does not help because somehow gdm proceeds to the KDE session although I did not choose it to be default session. So I had only CLI left.
I got over it by stopping gdm (/etc/init.d/gdm stop) and removing gdm and installing xdm. Anyway, what is the proper way? How to order desktop environment from CLI and/or where is the default desktop environment option written in a file?

Is there a command i can enter into the terminal or over an SSH session to make an Ubuntu system reboot a few hours later? Sometimes I want to reboot my server and it should take place in the middle of the night when I'm asleep.

I'm experiencing some weird short freezing issues in Squeeze and / or unstable. Everything works as usual, then the system will freeze for some seconds if I don't do anything, or resume faster if I move the mouse or hit a key on the keyboard. I thought it was a wifi related problem, as I have an intel iwl4965 , here is what I often see in dmesg:
[ 2608.910307] iwl4965 0000:06:00.0: Queue 4 stuck for 2000 ms.
[ 2608.910317] iwl4965 0000:06:00.0: On demand firmware reload
[ 2608.912832] ieee80211 phy0: Hardware restart was requested

I have been searching the forum regarding info about the debian testing going into freeze, but cannot find specific info regarding some of the facts. I understand that after some time the testing version (squeeze currently) goes into "freeze" before it becomes the new stable. Now, what does freeze actually mean? Currently I'm running Squeeze, and updating as the update software suggests, and since first install, I got a new kernel image, some updates to applications I use etc etc. So, when testing goes into freeze, all updates are stopped and only bugfixes are released, am I right? But I'm curious about one thing, for example I have gnome DE with let's say network manager applet 0.8.
So when testing is done with freeze and becomes the new stable - does it include current versions of kernel and programs that were actual during freeze? Will I have network manager applet 0.8 after freeze is gone to stable, or will it revert to... dunnno 0.7.6 version? At this time I have kernel version 2.6.32-5-686 , when I first installed it was 2.6.32-3-686 , so when going into freeze then stable kernel won't be downgraded, right? Btw I'm not using Sid's repositories. Well I least I think I'm not, the sources.list doesn't include sid's repos... Well sid non-free is there.

i'm running debian on a custom-built (no brand) box, which has been up and running for, maybe, 3-4 years with no issues whatsoever. all good parts... asus mbo, athlon, wd hd, etc. lately, every once in a while - like, say, every couple of days - i hear a "beep" from the box and the system freezes... lose the keyboard and mouse, and the display stays up but also freezes (for example, if a videos vid was playing, it would just freeze). have to physically reboot to get the system back. i assume this has nothing to do with the os or any app (although i'm usually browsing with chrome or ff when it happens). not being a hardware guy... can anybody clue me in as to how to figure out what's causing the problem?

My notebook seems to just freeze once in a while sometimes once a week, sometimes once in two weeks, sometimes once in two consecutive days. I cannot for the love of it narrow it down to anything. Granted, I have not followed the logs, but doing so for the first time gave no real results either.

Since I've installed Debian Squeeze, it freezes 2-3 times a day.
Usually the mouse pointer stops working and the screen remains unchanged, but sometimes it become white or distorted and the system halts.
Video is an older Ati 200m chipset (x300) with radeon driver and shared memory.
OS is Debian Squeeze x64
I've tried to modify xorg's settings. I've tried with and without KMS and compositing, different kernel, UXA/EXA/XAA acceleration, etc.
Maybe it was better with XAA, so the freezes reduced to an average of one per a day.
The version number of xserver-radeon-video-ati is 1:6.13.1-2-squeeze1.
The experimental repository has a little bit newer version of the radeon driver, but it depends on other xorg components, so it isn't simple to install and I don't know how to revert to testing/squeeze if I try to install it.

I'm experiencing constant system freezes, and was wondering which log file to view in order to determine what is causing it. I switched over from linux mint as it was giving me the same issues now being experience on my debian setup.
When my system does freeze, the keyboard is unresponsive (caps lock won't even turn on) and I have to use the power button to get out of it. The only thing that does work is my wireless mouse which I can still move around.

I am Debian Sid user and have some issues with my keyboard. I installed Debian some months ago and my laptop was always plugged on the external screen with external keyboard and mouse. For the fist time I took my pc at school and notice that when I close the lid (hibernate) then open it, I can't use my keyboard because of freeze. The screen turn on but the keyboard is dead. I have to close the lid few time and suddenly it work. Never face this problem before because with the external keyboard there is no issue.
I installed on the another HDD, Fedora, Mint, openSuse and the problem is the same.
I found some tuts like
- Open gksu gedit /etc/default/grub
- Find the line : GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
- Change it like this : GRUB_CMDLINE_LINUX_DEFAULT="quiet splash atkbd.reset"

I have just installed Debian testing on my new desktop and I am not very happy with performance - when I perform a disk intensive operation, e.g. upgrade packages in the system, everything seems to freeze, e.g. changing tabs in Iceweasel takes 3 seconds. I run the Debian on my 3 year old Thinkpad X60 ultra-portable, and I don't have these issues. (every single parameter of the laptop is much worse than the desktop).
I am using the default packaged kernel and scripts.
I run
hdparm -t /dev/sda1
And I got around 96GB/s, which is expected. What else can I try to make it work better?
rzes:/home/ga# hdparm -i /dev/sda
/dev/sda:
Model=WDC WD15EARS-00Z5B1, FwRev=80.00A80, SerialNo=WD-WMAVU1362357
Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }

You may say that this is hardwear error but its not, cus i can run grubs singel-user-mode and do whatever i want in the shell.
so my question is, how do i fix this from shell. I think maby I shld change something in xorg.conf but not sure what, and how.
