 Posted: Tue Nov 29, 2005 10:04 pm Post subject: problem with remote administration with ssh[SOLVE] |
 |
|
I intended to use a ssh client(putty or openssh secure shell) at school to do some time-comsumming tasks on my gentoo at home. At school, i login remotely as root to my gentoo at home and tried:
I saw a normal building process start, but i didnt wait for it to finish compiling the whole program, i disconnected from the server at home(i just click X on the ssh client, i didnt log out ). I though linux will continue compiling abiword for me, but when i got home, i recognized that abiword has not been emerged, i dont have it !!!
Is that normal? Is a session(in my case, root) will terminate as soon as i exit ?
If yes, then is there anyway that i can do a time-consumming task remotely(not just write a bash script and run it before going to school)? Sometimes when i am at school, i have to do some stuff on my comp, but i cant go home, so i need a way to control my comp remotely.

I think you'll find that 'screen' will solve this for you.
Then when you login remotely simply type 'screen' and you will start a 'virtual' terminal. Start your emerge (or whatever) in this terminal.
You can now 'detatch' this terminal by pressing 'ctrl+a ctrl+d' - the process (emerge or whatever) will continue in the background. You can logout, or be disconnected and the process will continue. To re-attach the detatched 'screen' simply type 'screen -r'. There is much better description of this on the forums somewhere, have a bit of a search.
Screen can do much more than this (man screen). |

While screen is probably better for a variety of reasons, it is always possible to do this without screen (assuming you don't want to watch the output) with something like:
| Code: | | nohup emerge foobar & |
This will put emerge in the background and it won't stop when you disconnect. You could also store the output with something like:
| Code: | | nohup emerge foobar > foobar.output 2>&1 & |
This will redirect output to "foobar.output", and redirected stderr there also.
