Programming :: Alter A Running Process Without Killing It?

Sep 7, 2010

In the comments section of this blog, the commenter "Pratik" claims that you can edit a running bash script, without killing it, and have the changes picked up by the running script. He claims you can do this by editing files in /proc. Now, I know how to find the /proc folder that contains the data on the running process, Code: cd /proc/`pgrep process_name` But I can't figure out what I should do if I want to edit a running bash script.

Ubuntu :: Killing All The Process On Restart/halt/shutdown Instead Waiting For Scripts?

May 9, 2010

I haveing a big problem atm (just after to upgrade to 10.04). I have a simply and easy script that sent a halt command to every KVM virtual machine actually running into the server. this script is/and was) palced as a init-rc script in rc0/rc1 and rc6 lvls. Just after to upgrade, I have noticed that this script is executed but the system ignore the time that it require to finish (giving time to correctly stop a single virtual machine). Aftert 5 second it start sending SIG-TERM and SIGN-KILL to any currect process and then reboot/halt.

I have just done a new script using upstart and I got just the same result. What is happending? why is the waiting the init secuence for a valid/or_not termination of any init script. I am so sorry for this crap english I have never study this language so I try to do my best anytime I speak it (or try ti..).

Ubuntu Servers :: Error: 'Can't Connect To Local MySQL Server Through Socket '/var/run/mysqld/mysqld.sock' (2)

Apr 10, 2010

After the upgrade from 8.10 to 9.04, all was well. But after the upgrade from 9.04 to 9.10, I lost the MySQL server. Now, I recall during the upgrade, I was asked if I wanted to keep the existing my.cnf file or replace it with a newer one. I did as suggested and kept the original as I had edited it before. The same question was asked with a couple other config files. I kept the original in each case. After the first step, I checked the server was running and the websites were up, all was well. After the update to 9.10, when I checked the server, I get the following error:

Code: error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)' Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists! Can anyone point me in the right direction to getting this resolved?

Ubuntu :: Scripting Timezone Changing Process?

Mar 25, 2010

I have worked on redhat/fedora for last 5 yrs but now working on ubuntu as well. I have around 200 ubuntu VMs on which I have to change the timezone.I know I can do that using "dpkg-reconfigure tzdata",But doing it manually on 200 machines is not what I really want to do.Hence I am looking for a way to script this process.On fedora, its simple,change the "ZONE" entry in "/etc/sysconfig/clock" and copy corresponding file from /user/share/zoneinfo to /etc/localtime. Hence I can script is easily.But in ubuntu, with "dpkg-reconfigure tzdata", I don't know how to script it.

General :: Shutting Down PC Without Killing SSH Sessions?

Aug 10, 2010

I have some heavy, long processes running on remote Linux machines. I use my laptop to SSH to these machine and run the processes from my couch.

BUT, when I want to shutdown my laptop, I am in trouble since the remote processes are killed.

I did my research and found out that "screen" is a great solution for me, it is! (As long as I don't SHUTDOWN my laptop). Isn't there a way to "persist" the "screen" sessions so I can shut it down and then re-attach to a session?

General :: ClamAV Killing RedHat 4.8?

Jul 19, 2010

I install the antivirus, ClamAV, onto a RedHat 4.8 box (yes it has to be that release of the OS to work with my other software needs) and after the install and giving the permissions to another user/group dedicated to this AV I get a ton of errors. After the install a few things pop up after a restart/logout. When trying to log back in the Gnome environment crashes so you cannot access any acct aside from using the text based environment. Two other error windows appear as well, one mentioning Bonobo has died and the other saying that Nautilus cannot be started due to Bonobo. I'm not too familiar with Bonobo can anyone fill me in on why those errors occured?

General :: Killing All Processes Of Current User?

Jun 15, 2010

user@host$ killall -9 -u user Will it definitely kill all processes owned by user (including forkbombs)?

No new processes is spawned to user from other users. No user's processes are in D-sleep and unkillable.No processes are trying to detect and ptrace or terminate this started killall (but they can ptrace or do other things with each other) There is ulimit that prevents too much processes (but killall is already started and allocated it's memory)

E.g. if killall will finish untampered and successfully is it 100% that no processes are left with this uid? If no, how to do it properly (with standard commands and no root access). Will SysRq+I definitely kill all things (even replicating)?

General :: Continue Running A Program Inspite Of Killing The Shell Which Invoked It?

May 31, 2011

Possible Duplicate: Leave bash script running on remote terminal while not logged in? I run a program, say ./a.out 10 from the shell prompt. Assume that there's a while(1) inside the program being run. Now if I try to close the shell, it warns me that it'll kill my running program too! So, how to kill the shell and still let my program continue running in the background?

I tried exec ./a.out 10 but the shell is still there. Another alternative is to simply double click my executable but then how will I pass command line parameters?

General :: Sending Signal From Child Process To Parent Process?

Sep 8, 2010

Code:

#include <stdio.h>
#include <unistd.h>
#include <signal.h>

[code]....

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.

General :: Process Scheduler A Part Of Process Queue?

Aug 12, 2010

as 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.
