 What does "not 'work'" exactly mean?

 Please post the actual error messages you get (plus what you tried).
 Assuming you talk about SSH, go to a terminal (xterm, konsole, ...)
 and try to login into one of your other boxes.  Post the SSH error
 message here.

 Attention: Don't forget to remove any possibly sensitive information
 like host names, user names, IPs etc. before you post here!

 Sorry, too little information to say anything.
