Deaf Shell is intended to be used as a shell for system accounts dedicated to
OpenSSH port forwarding, as in:
ssh -L [bind_address:]port:host:hostport] user@host
ssh -R [bind_address:]port:host:hostport] user@host
Deaf Shell will print some information and sleep until receiving a termination
signal (Ctrl+C or SIGINT from the user, SIGTERM from the system for instance).
It will also print a character every ten seconds.
At one point, Open Hub analyzed source code for this project based on code location(s) available at that time. Since then, the code locations have been removed.
