Inspired by the putty manager on Windows system, I have spent the whole afternoon to write ‘myssh’ – an interactive ssh management tool providing the ability to save, display, choose and connect your ssh connection automatically. I am not sure if there is any kind of GUI related stuff on Linux just like putty manager. However, if you are a CLI fan with some ssh connections, please try ‘myssh’. Hope it will save you some time and make you fun:)

# login list – add your login here

# hostname/IPaddr list – add your remote machine here

# password list – add your password here
passwdList=(“passwd0” “passwd1” “passwd2”)

# ssh list – add the relation rules to construct the ssh entry
# format: “login-remote-passwd”
# example: “0-1-0” stands for a ssh entry as below
# user0@server1 with password passwd0
