As the author of a telnet/SSH package, I have discussed this problem in
various forums over the years. Here is what I have learned.
It is often possible to prevent a process from being terminated when a
connection is dropped, by trapping the hangup signal (SIGHUP) generated by
the telnetd or sshd. However, I have never heard of a way to reconnect to
an orphaned session. So this is only half a solution.
The only solution I have heard of is 'screen', a utility on some
Unix/Linux systems that is intended for managing multiple sessions over
one terminal connection. But screen also has a capability to leave
sessions open, and a capability to reconnect to orphaned sessions.
I have often considered modifying the SSH daemon provided by OpenSSH,
freely available in source form, to allow for these options. Anyone
interested in funding such a project?
