[SOLVED] keep process running even after telnet session has been deliberately ended

sumeet inani · 03-28-2011, 03:58 AM

I have ubuntu 10.04 & I telnet to windows vista.
Even if I create a hidden process (http://www.commandline.co.uk/chp/ ) 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 ?

Hello,

Whatever script or command you start in a session, telnet and/or SSH, gets terminated if you disconnect the session, even if you've put it in the background for as far as I know. Have a look at the nohup command to disconnect your command/script from the console/session:

Code:

man nohup

Kind regards,

Eric

Actually I am running
'wget -b link -a log-file'
which gave message
'process sent to background with PID 2360'
but after I logout & login again , then I don't find wget.exe in tasklist which clearly indicates child wget of previous session ended.

Is there a way to create a process independent of telnet session ?

there is NOT 'nohup' in windows .
I am trying 'at' command .

Hi,

Sorry, didn't read correctly in your first post. If you connect from Linux to Windows and the process on the Windows side gets killed when you disconnect, then you should look at a Windows forum for a solution since the 'problem' clearly is Windows related. The nohup is indeed a Linux command to avoid the problem you have with Windows.

Kind regards,

Finally . I got solution

Code:

time /t @ this is current time
set /p tod=time to schedule task :-
at %tod% <command/batch-file>
You can verify using
schtasks /query /v /tn at<job ID>

This works in windows vista.

Still , I will say commands of linux are far ahead of windows (like there is no alternative of 'nohup' in vista)

Hi,

Although it being a Windows solution, thanks for sharing, sure it will be of use to others. And I completely agree with you, Linux is way ahead of Windoze on various things.

Kind regards,

Eric
