Fast remote command execution

fsh – Fast remote command execution

The problem logging in to a remote system with a cryptographic solution such as lsh or ssh takes time, due to the computationally expensive key exchanges that occur when the connection is established. It is common to trigger a lot of remote logins while using remote CVS, which makes it painfully slow compared to having the repository locally.

The solution reuse the secure tunnel once it has been established. fsh is a drop-in rsh-compatible replacement for ssh that automatically reuses ssh tunnels.
