Question or Symptom

I thought I saw a message about Telnet going away. Is that true?

Resolution

       Secure Shell (SSH) Will Replace Telnet at Southwest Cyberport
                             on October 15, 2001
 

Beginning October 15, 2001 Southwest Cyberport will no longer accept telnet connections. Only users of our UNIX shell accounts will be affected by this change. If you do not know what Telnet or a shell account are you can safely ignore this message (only 6.4% of Internet users use telnet). This change will *not* affect any other service, such as web browsing, email, FTP, or Usenet News.

Only SSH access to shell accounts will be allowed. We do not wish to discourage remote logins. However, we strongly believe it is neccessary for a secure protocol like SSH to be used for remote logins. If you're interested in more information about why SSH is important you should visit http://www.openssh.org/faq.html#1.2

There are other common protocols in use which are also insecure such as POP and IMAP. We have decided to eliminate Telnet first largely because there is a widely-available replacement, SSH. We will be working to provide secure versions of the other protocols in the near future.

If you do not already have an SSH client and you intend to login to our UNIX network, you will need to install one. There are many free and commercial versions readily available:
