Like any good open-source program PHP Shell shouldn't
be afraid of mentioning some of the alternatives out there.
An incomplete list would be:
* SSH. The Secure Shell is the standard solution to
the problem that PHP Shell tries to solve. SSH lets
you login to a remote system in a secure way where the
traffic and password is encrypted at all times. You
can also upload and download files securely and make
encrypted TCP tunnels.
If your host supports SSH then use it and forget
about PHP Shell or any other solution.
* Telnet. This is the old way to obtain an interactive
login on a remote system. Unfortunately telnet is
insecure since the password and subsequent traffic are
sent in clear text. SSH was developed precisely to
replace telnet. The advantage of telnet over PHP Shell
is that it gives you an interactive session.
