We are in the process of converting over to openssh at UNC.
I've built openssh 2.20p1 for all supported platforms at UNC:
AIX 4.3
AIX 4.2
Linux 2.2
Solaris 2.7
Solaris 2.6
SGI 6.5
We been running for about a month now and have only one reported
problem--which came up today:
When running ssh on a machine running SGI 6.5 you get the following error:
%ssh overlord
rsa_public_encrypt() exponent too small or not odd
I see that this error message is coming from procedure rsa_public_encrypt()
in file rsa.c, but I can't figure out what is wrong. Any idea what might be
causing this
problem? The problem occurs if you are running an old sshd or an openssh
sshd. I can run
ssh 1.2.26 fine on this platform.
Here is the output of openssh's ssh -v:

===========================================
We can't completely convert to openssh at UNC until this problem is solved
(obviously!).
Thanks for any help you can give.
