fsh: A tool for fast remote command execution
- Summary
- Remote command execution via a cryptographically strong method such as
lsh or ssh is often painfully slow, especially if either of the
involved computers is slow. The biggest problem is that the client and
the server perform a lot of complex calculations during connection
establishment.
fsh uses lsh or ssh to establish a secure tunnel to the remote
system. This takes as long as a normal connection establishment, but
once the tunnel is established, fsh can reuse it to start new sessions
on the remote system almost instantaneously. You get the security of
ssh and the speed of rsh.
Note that fsh is going to be obsoleted by OpenSSH itself. The OpenSSH
daemon has supported multiple shell channels over the same connection
for a long time, and since OpenSSH 3.9, the client is starting to
support it too -- See the documentation of the new ControlMaster
and ControlSocket options.
