Java SSH library

 Trilead SSH for Java is a freely available open-source library which
 implements the SSH-2 protocol in pure Java (tested on J2SE 1.4.2 and 5.0). It
 allows one to connect to SSH servers from within Java programs. It supports
 SSH sessions (remote command execution and shell access), local and remote
 port forwarding, local stream forwarding, X11 forwarding, SCP and SFTP. There
 are no dependencies on any JCE provider, as all crypto functionality is
 included.
