If you work on remote system in the terminal mode. If you want leave a working programms after disconnect from the terminal. For that you can use screen programm. But in the some cases this programm not installed on the system.
For it we have a simple decision.
1. You should upload a binary file of screen to the remote server. Any i386 or x86_64 and verify all libraries.
user@remote-server [~]# ldd screen
libncurses.so.5 => /usr/lib/libncurses.so.5 (0xb7eb6000)
libutempter.so.0 => /usr/lib/libutempter.so.0 (0xb7eb4000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x003ad000)
libc.so.6 => /lib/libc.so.6 (0x0023b000)
libdl.so.2 => /lib/libdl.so.2 (0x00396000)
/lib/ld-linux.so.2 (0x0021c000)
user@remote-server [~]#
Seem everything is ok.
2. Screen wants get variable of environment – SCREENDIR. When we set value for this variable in the user space, then we set the secure directory for screen’s socket. It is very important if hosting resides on the shared server.
For example, just add rows to yours .bash_profile and make the directory screen in the $HOME.
cd && mkdir screen; echo SCREENDIR=$HOME/screen >> .bash_profile echo "export SCREENDIR" >> .bash_profile
And make relogin
3. Next just test its.
For example:
user@server [~]# ./screen -d -m -S curl 'htop'
user@server [~]# ./screen -ls
There is a screen on:
222053.curl (Detached)
1 Socket in /home/user/screens.
user@server [~]# ps -eF|egrep htop
user 222053 1 0 1399 808 6 13:12 ? 00:00:00 ./SCREEN -d -m -S curl htop
user 222054 222053 3 3842 1356 6 13:12 pts/1 00:00:00 htop
user 223524 166121 0 15822 800 6 13:12 pts/2 00:00:00 egrep htop
user@server [~]#
All are done!
