Small question regarding SSH
I am looking for some model like this:

My Computer
-------------
Intermediate Server (IS)
-------------
Own Server

I must be able to ssh into the Intermediate Internet Server which is generally an online version of SSH service through which I will connect to Own Server. I was the IS to keep the connection alive to the Own Server even if I disconnect from IS. Is there a way I could do this? Are there any free services on the internet that provide this? The reason I want this is because the "Own Server" kill my processes even when I'm running as a root or if my script outputs an error. So I want some way of keeping the connection alive and writing the outputs to that file so that when I log back into IS, it should show me.

Alternately, is there a way I could just direct all output from programs into a file rather than the screen? it somehow happens that when a background task is running and the program outputs something or pops an error, if I'm logged in, it runs perfect but when I log out when a background task is running, it just kills my process...
