Server :: Another Session Logged In But Running No Processes?
Jan 30, 2011My University gives us access to a Linux server, named stud1.
Code:
me@stud1:~$ uname -a
Linux stud1.some.univ.ac 2.6.9-89.31.1.ELsmp #1 SMP Mon Oct 4 21:41:59 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
Apparently I was logged in, and never logged out sometime:
Code:
me@stud1:~$ who
<snip>
me pts/37 Jan 30 13:27 (6.6.66.66)
<snip>
me pts/58 Dec 30 19:13
but when trying to find out why I'm still logged in, I can't find it:
Code:
me@stud1:~$ ps faux |grep me
root 30030 0.0 0.0 51128 4360 ? Ss 13:27 0:00 \_ sshd: me [priv]
me 30033 0.0 0.0 51132 2336 ? S 13:27 0:00 \_ sshd: me@pts/37
[code]....
how can I logout this unused session?
Security :: Checking What Processes Are Hidden?
Jan 13, 2010I post this to have a memo about how I looked into this problem. You can use this command to check what is hidden.
Code:
/usr/lib/chkrootkit/chkproc -v -p 3 | grep /proc/ | sed 's/.*(/proc/[0-9]*).*/1/'| xargs -n1 -I %%% cat %%%/cmdline
If it doesn't output anything, then nothing is hidden currently. This usually means that a process was started between the ps command and the /proc check of chkrootkit. You can check what those command(s) are by running the above in a loop, with high priority.
[Code]...
Does anyone know how to get rid of these false positives while retaining other functionality of chkrootkit?
Software :: Server Gets Slow And The Load Goes Up, There Is A Bunch Of Processes Call Mi_dmonq Running?
Oct 17, 2010I am running Red Hat Enterprise Linux Server 5.1. I notice that when my server gets slow and the load goes up, there is a bunch of processes call mi_dmonq running. Does anyone know what this process does? I tried to find it online but didn't find anything. Also, I tried to find the binary on the server but find doesn't return anything. Does anyone know what it is?

Jan 4, 2011I have something like:cd project && python manage.py runserver &cd utilities && ./coffee_auto_compiler.pyAnd I want both of them to close on Ctrl-C (or some other command). How can I accomplish that?EDIT:I tried using jobs -x kill and kill `jobs -p `, but it doesn't seem to kill what I need. Here is what I mean:oon 8119 0.0 0.0 7556 3008 pts/0 S 13:17 0:00 /bin/bashmoon 8120 6.8 0.4 24568 18928 pts/0 S 13:17 0:00 python manage.py runserverjobs -p give me just process 8119, but I also need to close 8120, since it's the thing that the first command opened.If it helps, the commands are actually in a Makefile, and I want it to run two daemons at the same time (and somehow close them at the same time).

View 1 Replies View RelatedUbuntu Servers :: Run High-priority Multi-threaded Processes In The Background?
Apr 7, 2011Using Ubuntu server 10.04.2 64-bit all up to date.
I am running multi-threaded processes. These use OpenMP in my own code and the multi-threaded ACML maths library. When run in the foreground, everything is fine i.e. if I have set
export OMP_NUM_THREADS=8
then when I start all 8 cores are in use and things whizz along. However, when running overnight and logged out using e.g. 'at now + 1 minute' then the command, I am only getting about 130% CPU and it slows down accordingly. I have tried renice'ing and calling from within a bash script in case sh is doing something odd but nothing seems to solve it. I am sure that in the recent past this wasn't the case.
The libraries being used are shared versions in case that might have any bearing.
Debian :: Htop Showing 50+ Processes Of /usr/sbin/console?
Jun 16, 2011This might be nothing but when booting a computer directly into the console (tty), and running htop, I expect the list of running processes to be very short, but it turns out I have more than 50 instances of /usr/sbin/console-kit-daemon --no-daemon running (see screenshot below). Is this normal?
View 2 Replies View RelatedGeneral :: Shell Script Is Showing Error After Whenever Checking A Special Variable
May 29, 2011I have created a shell script to customise mv command, now i have achieved to accomplish all the functionality of mv by using alias. But i found difficulty in accomplish the funcionality with options [Like mv -i or mv -f etc.]. I thought about logic which check the first argument whether its starting with a minus [-] or not. if its starting with argument it will set a flag and execute accordingly. But whenever this condition is checked it shell script will throw error of destination operand missing. But the same will work with out option.
Note: I have used an minus[-] expression for decreasing a counter on the script above. The below mentioned is the portion of script. Sry for troubling Im not gud @scripting.
for i in $*
do
{
argument=`expr $argument - 1`
if [ $argument = 0 ];
then

I can do normal things. and by the way, nvidia driver was already installed.

Jan 5, 2010My mouse cursor has acquired some strange background image showing what looks to be paragraphs of chinese glyphs (they are too small to make out clearly). This background image is contained in rougly a 1 inch square with the mouse cursor hot spot in the upper left-hand corner. The mouse cursor is visible, but whatever is under those glyphs is covered.
I've tried the mouse configuration gui -- but it says nothing of background images for the mouse. I've also deleted and recreated my xconfig.org file to see if that somehow got mangled. I've been searching the web for a couple of hours, but cant seem to find anything related to my problem.

Ubuntu :: Ssh Banner With The Number Of Currently Running Processes?
May 18, 2010I would like to do the following: Create a banner for any user logging in through ssh which warns him/her about the number of processors being used already by other users (or conversely the number of free processors). For example, if a user logged in he would then see a message like: Warning! 7 out of 8 processors are in use.I already figured out how to do a banner and with ps -e -o pcpu I can get all processes' %CPU usage. I think I would like to count the number of processes which have more than 90% CPU usage and output this number ("7" in the example) in the banner

Aug 18, 2009I have p1,p2,p3,p4 some processes created by me in C. p1, p2, p3 are started individually from several consoles. And I want process p4 to terminates processes p1, p2, p3 if they are running. Which is the easiest way to accomplish that? put all processes in the same process group and send from p4 a kill signal to the group. But I couldn't do that because I cannot call successfully setpgid(getpid(), 15000) from p1-p4. It's there some way to put them in the same group? the processes don't have a child-parent relationship, they are launched manually from consoles.
