General :: How To Find And Kill Remote Processes
Oct 28, 2010I am developing a daemon that is acting up and I am now unable to create any new processes (ie. I cannot start a new process to kill the other rogue processes). So, I need to be able to kill the processes from a remote machine. How do I do "kill" remotely without admin privileges? If I cannot kill my own process from a remote machine as a normal user then tell me so I can mark it as the correct answer.

Jun 21, 2011I have a linux server top reports about 9GB of swap used:But I cannot figure where's it use swap, some google results said that top - O commad follow by p will show swap usage by process. But as shown in the above image, taking a brief sum of the SWAP column shows that > 10GB of swap is used, so where does the 9GB figure for swap usage come from? Top reports that about 96492kb of ram is used by buffers. Is there anything I can do to utilize this, instead of using swap?
View 1 Replies View RelatedGeneral :: Script To Find Disk Utilized Processes?
May 25, 2011I have written a script that triggers a mail if the server load average goes beyond a specific value.
The mail contains following field Current Load average. Top 10 CPU utilized processes.
Code:
ps -auxf | sort -nr -k 3 | head -10
Top 10 Memory Utilized processes.
Code:
ps -auxf | sort -nr -k 4 | head -10
But the problem is that whenever there is any disk related activity happens the load gets high and the command (for ex.mkfs.ext3 /dev/sdb1, dd,scp,cp)which are the main cause behind the load average doesnt get displayed in top 10 CPU/Memory Utilized processes.
Is there any way of finding top 10 processes for Disk related activity?

View 10 Replies View RelatedGeneral :: Turn Off Monitor (Energy Saving) While In Text Console Mode
Nov 3, 2010How to configure Linux text console to automatically turn of the monitor after some time? And by "text console" I mean that thing that you get on ctrl+alt+F[1-6], which is what you get whenever X11 is not running. And, no, I'm not using any framebuffer console (it's a plain, good and old 80x25 text-mode). Many years ago, I was using Slackware Linux, and it used to boot up in text-mode. Then you would manually run startx after the login. Anyway, the main login "screen" was the plain text-mode console, and I remember that the monitor used to turn off (energy saving mode, indicated by a blinking LED) after some time. Now I'm using Gentoo, and I have a similar setup.
The machine boots up in text-mode, and only rarely I need to run startx. I say this because this is mostly my personal Linux server, and there is no need to keep X11 running all the time. (which means: I don't want to use GDM/KDM or any other graphical login screen). But now, in this Gentoo text-mode console, the screen goes black after a while, but the monitor does not enter any energy-saving mode (the LED is always lit). Yes, I've waited long enough to verify this. Thus, my question is: how can I configure my current system to behave like the old one? In other words, how to make the text console trigger energy-saving mode of the monitor?
Ubuntu :: Find Cumulative CPU Time For Processes For An Interval?
Feb 20, 2010I want to find the cumulative CPU time used by each process between two points (defined by the user, e.g. running a command or clicking a button).
A first stab at this would be running
Code:
ps -eo pid,cputime
at the beginning of the interval and at the end, then doing some arithmetic on the two sets of results. But this only shows whole seconds of cputime ... and what about processes that started and stopped during the interval?

View 3 Replies View RelatedProgramming :: Find Number Of Child Processes (C / POSIX)?
May 26, 2010I'm in the process of writing a program that is a server- it will accept connections and stuff, and spawn a child process for each. However, i've run into a small problem. I do NOT want to bother with keeping track of the processes unless i need to. So, i set SA_NOCLDWAIT (#ifdef) on a SIG_IGN to the SIGCHLD handler through sigaction interface. The standard says that it the kernel will then keep track of reaping zombie processes for me (a HUGE plus). However, upon receiving a SIGINT signal, i want to stop the server from accepting new connections (done), and then wait for there to be no new connections. I was thinking of just putting a loop like so:
Code:
while((wait(NULL) != (pid_t)-1) && errno != ECHILD);
However, I'm not *sure* that this will work, especially with SIGCHLD still ignored. So how can i tell if there are still child processes? I can't find any call like int getnumchld(pid_t proc); (i wish). Plus it would be inefficient to spin on that function anyway. OTOH, i would rather *NOT* have to do the same thing in a loop with a system("ps |...>file"); read(file); etc. either. Is there a way i can portably implement this feature (I was hoping i could run it on linux and the major BSDs, at least).
TO SUM IT UP:
How can i tell if a process has no child processes if i've SIG_IGN'd SA_NOCLDWAIT'd the SIGCHLD? Is there a _reasonably_ portable way to do so? I *don't* want to manually wait for EVERY process. Maybe only those still active at the time of SIGTERM, but that requires keeping track of the number of connections and whether those have terminated...
EDIT: Does anyone know if the above code *would* work, even with SIGCHLD ignored and the kernel cleaning up zombies *for* me? I checked the manpage and it doesn't say much.
EDIT1: Note that all of the processes are in the same process group and session. SO i can find them through this as well. Perhaps even setting the uid/gid and finding all processes run by that group?
EDIT2: i have an idea if the above isn't feasible. If there is no "elegant" way to do it, i could reduce the complexity by sending a SIGUSR1 to the whole process group. Each process would then set a flag telling it to send a SIGUSR1 in reply and send a SIGUSR2 when it is done executing. Then i could keep a count of signals. Maybe that would be *easier*. Or perhaps a count of all child processes and just a termination signal to decrement the counter.

Apr 30, 2011I need to create a small list of processes in a monitor.conf file. A shell script needs to check the status of these processes and restart if they are down. This shell script needs to be run every couple of minutes.
The output of the shell script needs to be recorded in a log file.
So far I have created a blank monitor.conf file. I have gotten the shell script to automatically updated every couple of minutes The Shell script also sends some default test information to the log file.
how I go about doing this part ? A shell script needs to check the status of these processes and restart if they are down.
I have put in the conf file the below commands but I am not sure if this is right.
ps ax | grep httpd
ps ax | grep apache
I also dont know if the shell script should read from the conf file or if the conf file should send information to the shell script file.
