When a process supports daemon mode, you can either run it in a screen instance or init.d script.
If you had to kill off a rogue daemon and need to start it again via SSH, you can restart the daemon with a very simple addition to the command:
For example you have /bin/daemon_process with the parameters "--daemon --log-path=~/logs/blah/"
You can execute it with:
/bin/daemon_process --daemon --log-path=~/logs/blah & The extra & at the end makes it spit output to the current terminal, but it wont wait for the daemon to finish.
The nohup command can save your bacon if you want to run plain commands that can survive a dropped SSH connection. The following snippet will run the command in the background and log any output to the specified logfile:

You'll have to kill the process when you no longer need it, of course.
