Yessh is a bash program that uses the SSH client. It provides fast connections to Linux/Unix hosts. Just type the name you have chosen for a host, and yessh will connect you via SSH. You don't need to remember the IP address, hostname, login, or password; just one arbitrary name. Accounts with passwords are kept in a secure file where passwords are encrypted using OpenSSL with 128-bit AES. You can use the autoconnect function to connect to your server with 5 keypresses.
