'fsh (fast remote shell)' is a drop-in rsh-compatible replacement for ssh that automatically reuses ssh tunnels. Also included is fcp, which is a drop-in replacement for scp that uses the same tunnels. Logging in to a remote system with a cryptographic solution such as lsh or ssh takes time. This solves the problem of slow logins due to the computationally expensive key exchanges that occur when you establish a remote connection is established with a machine that has ssh or lsh.
