   Ah.  Would you like to commit this fix should I?  Relevant files
   are libtelnet/{auth,enc_des,encrypt,misc}.c.  Or maybe just do it
   for all of libtelnet/.

If you can do it, then it would be wonderful.  Otherwise, I'll try too
see if I can get some time to eiither resurrect my old patch, or just
do it anew.

   That seems like the same problem as in GAP:

        Copying and distribution of this file, with or without modification,
        are permitted in any medium without royalty provided the copyright
        notice and this notice are preserved.  This file is offered as-is,
        without any warranty.

   The intention is to permit both commercial and non-commercial
   distributions, as far as I understand.

Maybe it is OK then.

   Btw, I suspect a lot of this code can be removed, it refers to old
   authentication types (e.g., SPX, Kerberos 4, rsaencpwd) that no
   longer works for other reasons.

Yeah, sounds like a good idea.  There is alot of cruft in inetutils
that dates baack to the 4.4BSD-Lite days, and alot of it is dead code,
or broken code.
