I've always wondered whether my process kills when I am in the process of doing something during my ssh session. For instance, I ssh from my local box to dev-formbox and did an scp transfer to another remote host. All of the sudden, I lost ssh connectivity on my local box due to network issue. Will the scp process (or any of my process that I am currently doing) kill also once I loose the ssh session?
View 1 RepliesI am reasonable linux skilled. I am running a VPS account with Debian Linux Lenny, Virtualmin/Webmin. This has only recently started but I don't know at what point, as haven't done much on it recently but applied some updates. There's always at least 50% free ram when it happens (of 512mb) and basically no CPU activity. I've even tried killing off all process's apart from what I believed to be needed to test, (init, sshd, loggers). I can find mention of the action anywhere in any logs, even though I have klogd and syslog running. It seems to happen at varying intervals fairly regularly with certain processes. I've had it happen with a big 'rm -r' but more regularly with make's , make install's, apt-get (while its awaiting your reply to proceed), and rtorrent.
All I get is "Killed" and back to prompt,
If I type "echo $?" I get '137'
In Ubuntu 10.10 on a REALLY old laptop, everything works fine - except the system occasionally gets a lag spike, where the CPU is suddenly being throttled. This wouldn't be a problem, except my mother's using the laptop to play backing music for her choir and the CPU spikes are causing the music to stutter. After much searching and eventually resorting to TOP, I found that the CPU was being throttled every 10-20 seconds or so by a process called, "kslowd001". "sudo kill -9 `pidof kslowd001`" did nothing, nor did, "sudo killall -9 kslowd001". It doesn't want to die, it just wants to throttle the CPU, and I just want it to stop. What does this process actually do? Why can't I kill it? How do I switch it off, or otherwise stop it from throttling the CPU every couple of seconds so that we can actually listen to music or watch videos from the laptop?

View 5 Replies View Relatedrecently a weird error occured on my Ubuntu Karmic. When I shutdown (or reboot) the os, the flashing logo shows and then the whole process hangs with last few lines of shutdown log displayed. The last line then says this error:

Then I have to shutdown the computer manually with hardware button. It's no big deal, it's just not that comfortable and I'd really like to know why this is happening.
I just installed Ubuntu on a Cr-48 netbook, which has an odd custom bios which can't boot regular bootloaders/kernelsI'm therefore using the existing kernel on the machine rather than the Ubuntu one, with no initrd/initramfs, just booting directly to the Ubuntu root filesystem.t's just a minimal text mode install right now, from the alternate installerAt boot time, plymouth crashes.

I enter my credentials, it appears to login, and immediately goes back to the login screen. Note that under tty1 I can still login with my user account and do everything.
I can still login with root in the gui.

I have ubuntu 10.04 & I telnet to windows vista. Even if I create a hidden process [URL].. from batch file . It seems the process gets killed when I end connection at port 23 to host. Maybe , the hidden process created is still child of current telnet session so tree is killed as session ends. Is there a way to keep process running even after telnet session has ended ?
View 6 Replies View RelatedThere are often times when the best way to launch an application is from the terminal, but it is a graphical application and after it is launched the terminal is useless.
Examples of places where a terminal is convenient are when a process starts lots of child processes and is also unstable; you can be sure to kill all of its children simply by using Ctrl-C at the terminal. Also it allows me to read program output and to set up the terminal environment to be optimal for the application (for example "unset LIBGL_ALWAYS_INDIRECT")
With GNU screen, I can get around the hassle of having a terminal window open by using something like the following in a terminal window:
Code:
screen
my_command
Ctrl-A d
and then I can close the terminal and the program will keep running. Then I just type "screen -r <Tab>" (the tab will get me my screen session if there is only one such session) in any terminal window, even a tty, and I can get the screen session back and use Ctrl-c or something.
So my question is, is there a way to do this automatically so that a launcher or script will start a screen session, inside that screen session start a process, and then detach from that screen session without me having to manually open and close a terminal and type the commands?
I am downloading a big file on linux VPS, and I am connecting remotely via Putty to do it? Once I initiated the wget command to download the file, if I close the putty window, will wget continue to download the file in the background even though the session is technically closed?

I use tmout = 15 min in my /etc/profile (along with readonly tmout). i have some issues i need to address, looking for ideas.
1. what is considered a idle "session" ?
2. if i & a process to the background and do nothing is this a idle session?
3. if user uses su to a higher level, are there now two sessions? is the tmout for user suspended until su user time outs or leaves su session?
4. i have some users who will run long sql queries. is there a workaround to have the session remain active until process has finished?

Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.

View 1 Replies View Relatedas we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.
So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.
