ssh

ssh2 [-l user ] host [commands ]
ssh2 [options ] [user @ ]host

Secure shell. This is a secure replacement for the rsh , rlogin , and rcp programs. ssh uses strong public-key encryption technologies to provide end-to-end encryption of data. There may be licensing/patent issues restricting the use of the software in some countries.

Note: ssh2 is not distributed with SVR4 or Solaris. Source code for the noncommercial version for Unix can be downloaded from ftp://ftp.cs.hut.fi/pub/ssh . More information can be found at http://www.ssh.fi and http://www.ipsec.com .
