PATCH INFORMATION
-------------
Berkeley Software Distribution (BSD)

     A source-code patch, along with the domestic version of the most
     recently released Telnet sources from Berkeley, are available by
     anonymous FTP from
     
         net-dist.mit.edu:/pub/telnet/telnet.patch
         MD5 65d56befe3d0f1699d38de5509552578

     There is also a PGP ASCII signature file for the patch in
         
          net-dist.mit.edu:/pub/telnet/telnet.patch.sig
          
     This patch can also be found in CERT Advisory CA-95:03, Appendix B.
     (Note: Do not calculate a checksum for Appendix B alone. It will not
     match the checksum of the FTP version of the patch because the tabs in
     the FTP copy have been replaced with blank spaces in the CA-95:03
     Appendix B copy.)

FTP Software, Inc.

     Customers of FTP Software with an encrypting telnet (provided in the
     PC/TCP or OnNet packages) should call the FTP technical support line
     at 1-800-282-4387 and ask for the "tn encrypt patch".
