Now comes the hard part, creating your hosts file.

The script wants it to be in the same directory as the script with the namehosts. This is the syntax:

ID,Friendly name,username,host or ip,port1,VPS 1,-,vps.example.org,222,VPS 2,www,vps.someserver.com,22223,Home Router,root,192.168.1.1,224,Homeserver,-,192.168.1.10,225,Work,ceo,my.work.com,22 

If you want the current user to be used as the username then use a - (dash) asusername.

Please double check your comma's and your numbers, if something is wrong thescript can give strange errors.
