Fedora :: Disowning A Process Started In A Ssh Session?
Sep 10, 2009
I started a process in a PuTTY session that I want to survive after I've disconnected. I issued a `disown` on the process (forgot to add the -h option). I've attached a small summary of the commands issued within the PuTTY session as well as an excerpt from the pstree (essentially switched user contexts twice, issued command, suspended program, disown'ed, resumed program
Command summary
Code:
> su -
> ...
> su -l <useraccount>
> ./myprogram

I remember modifying some file. I really can't remember what it was now.... But ever since, when I run something from terminal, I get this:
Code:
(<unknown>:1797): atk-bridge-WARNING **: AT_SPI_REGISTRY was not started at session startup.
(<unknown>:1797): atk-bridge-WARNING **: IOR not set.

I started a 'dd copy�ng' of one disk drive to another. Both disks are hooked to a remote machine and I initiated the dd command by ssh_ing into it.I have to shut down the box from which i initiated the ssh session.Is there any way I can keep monitoring the status (shell script)of the copy process, ie know when the dd command terminates and whether it terminated successfully .I could then ssh into the macine from another box and still know the status.

Consider I am logged on a machine via SSH.I execute a process having "&" at the end from a shell - I run the process in background.Then I log off from the machine.I am just wondering if it is possible to bring that process to front after I log onto the machine again?I would like to check the output of my running process.Or is there any different approach to have a process running in background and to be able to view its output (i.e. printf)

I need to kill a process which has been started by user2 if I am user1 without being sudoers or using root.Do you know if there is a way of setting that when launching the process? Such as a list of users allowed to kill the process?

I have a startup script placed in /etc/init.d wherein I make the following call:
nohup sudo -u myuser $CATALINA_HOME/bin/startup.sh 2>&1
This causes Tomcat to be run as myuser, which is expected. However after issuing the reboot command the system starts up and root is now the owner of this process. How can I force the process to be started off as myuser on reboot?

We have a Oracle 11.2 database running on Red Hat 5.5. The database have a scheduled job to fetch some files from another server using ftp, and herein lies the problem.he job runs a pl/sql that runs the function in an (by us compiled) external libraryThe ftp-functionality itself is done by using libncftp and it's API's.The process starts correctly, but then trying to login to the actual ftp host, ncftp only reports "Unknown username/password" (which is not the case).I have the exact same code in an executable and when run from an interactive shell, it works fine.So the only thing I can come up with, is there are differences when the process is started by Oracle, rather then being ordinary" process.And I am stuck.If there are any environment variables, paths etc missing when running the extproc-process, how do I find out which?Because the real problem is NOT wrong user or password.

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?

I am using putty to interact with Linux server. I have started a process using putty.
The process is running and will take 5-6 hours. I want that process to keep running after I close the putty session. How can I keep that process alive after closing the putty session? I do not want to keep the computer ON all the time. Is there any way to do this?.

I was working normally and the GUI just failed, all I could still see were any open windows. I rebooted the machine from tty1 and now I can't login anymore under my normal user accounts.
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.
/var/log/messages says this
Code:machine checkproc: checkproc: can not get session id for process 9839!

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 ?

There 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 installed slackware 12.1 from files i downloaded and converted to cd (images). There are six "disks" i downloaded from the slackware site and converted to images via a homemade .cmd in windows xp and then burned using imgburn.
I partitioned my hd (canibalized from an acquaintance's emachine and connected it to my desktop (1G ram, 2Ghz processor). Booted from disk 1 and fomatted the 80G HD for 2 partitions of linuxswapable at 2G apeice and 2 partitions of bootable linux. (Because i want to try another distro later). I ran the setup installing most everything and all seemed to go well. After i exited setup and restarted, it identifed the cd/hd as normal and then went into some sort of recovery mode with the emachine logo call pcangel, after which it tells me.
STOP: c0000021a (fatal system error) The session manager initialization system process terminated unexpectedly with a status of 0xc000003a (0x00000000 0x00000000). the system has been shut down. So, is this indeed an xp error message, and if so, why am i getting it after formatting everything?

I recently installed KDE in my ubuntu 10.10. To access KDE, I want to use
startx /usr/bin/startkdeBut using it disables sound in KDE (Sound is working fine in GNOME). It doesn't sound for anything like login sound, totem, mplayer or any other playerBut when I press Alt+Ctrl+F1 to change to virtual console, the playback resumes from where it was in time and when coming back Alt+Ctrl+F7 and the time in totem (or any other player) doesn't move. While log out also it doesn't play logout sound and doesn't logout, so I have to press Ctrl+Alt+F1 so that logout sound play then it exits.When starting KDE by kdm or gdm, the sound works normally. But I don't want to login again using kdm or gdm and not to use root user to start kdm or gdm.I don't know what is the difference between when KDE is started by startx or by kdm/gdm where the same user login in kdm/gdm as that for startx

I've noticed that after an X11/KDE "End Session" it takes a long time to actually "shutdown" and return to standard terminal prompt. Also returning to the terminal prompt I get error messages from kwin, akonadi, and other X11/KDE based error messages.Does anyone know how to speed up the "End Session" process or how to eliminate terminal error messages that are displayed after shutdown?

My screen has started freezing periodically. The mouse still moves the cursor but nothing else responds. Ctrl-Alt -F1 doesn't give me a terminal screen nor does Ctrl-Alt-Backspace restart X I must turn off the computer and turn it on again to reboot. I don't remember having this problem with Fedora 11, but I recently moved to Fedora 12. I am using the kernel
2.6.32.14-127.fc12.i686.PAE
Looking at /var/log/messages,
I find repeated instances of the error message
[drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(4).
before the reboot.
Google provides many references going back to April for this string, mostly on Ubuntu related sites. I do have an 128 MB ATI Radeon X300 graphics card but it is over four years old, and I didn't have this problem with earlier versions of Fedora. Also, the google references seem to refer to hibernation, which I am not doing, at least not intentionally. Finally, I see that Xorg configuration has changed significantly since I last checked. (I can't find xorg.conf.) Can anyone refer me to a relatively succinct description of how it now works?

when I try to run yum I get this:
Quote:
There was a problem importing one of the Python modules required to run yum. The error leading to this problem was:
No module named yum
install a package which provides this module, or verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.6 (r26:66714, Mar 17 2009, 11:44:14)
[GCC 4.4.0 20090313 (Red Hat 4.4.0-0.26)]
how am I supposed to install a package without my package manager?
I can't install software via System/Administration as well.
It's so weird that I can't find any threads about this, apparently I'm the only one with this problem.

I recently installed Fedora as dual boot with XP on my netbook, but then decided to uninstall it again. I probably did it in the wrong way because everything is messed up. I installed Fedora in a separate partition, so I just deleted that partition. Now when I rebooted my netbook, it starts GRUB.
I get some sort of command prompt like cmd.
grub> {here I can type commands}
I tried several stuff to get everything normal again. First I made a bootable USB which starts the XP Recovery console. Then I used these commands :
Code:
fixboot
fixmbr
I reboot, and there it is again ... the GRUB. How can I get Windows XP working again? I didn't touch the C: boot partition, so the XP installation should still be intact.

I was having a job in /etc/event.d. It was working fine upto FC12. With upgrade to Fedora 13, it stopped working . Searching the internet, It looks like /etc/event.d is obsolete and I need to use /etc/init. Also the filename has to have a '.conf' extension. So I have renamed my job as /etc/init/svscan.conf.However, it fails to start automatically on reboot . It works if I manually issue the command % sudo /sbin/initctl emit qmailstartBut fails to start automatically on reboot. Is there anything wrong in my script below ? Let me know if I have missed out anything?
% cat /etc/init/svscan.conf
