Net::SSH::Perl is an all-Perl module implementing an SSH (Secure Shell) client.
It is compatible with both the SSH-1 and SSH-2 protocols.

Net::SSH::Perl enables you to simply and securely execute commands on remote
machines, and receive the STDOUT, STDERR, and exit status of that remote
command. It contains built-in support for various methods of authenticating
with the server (password authentication, RSA challenge-response
authentication, etc.). It completely implements the I/O buffering, packet
transport, and user authentication layers of the SSH protocol, and makes use of
external Perl libraries (in the Crypt:: family of modules) to handle encryption
of all data sent across the insecure network. It can also read your existing
SSH configuration files (/etc/ssh_config, etc.), RSA identity files, DSA
identity files, known hosts files, etc.
