RS-6000, AIX 4.1.4, target same,
using AIX's own compiler (xlc? whatever it's called)
System: AIX dbatest 1 4 000057973500

Show quoted text
I have compiled and installed K5 1.0 on the above machine.
I can get tickets, either locally or from Windows.
I can run gssftp locally with no problem.
When I connect to the encrypted telnet, the daemon gets through the
authentication OK, but as soon as it tries to fork for the
new user, the AIX host crashes (as in core dump) and I have to
cycle the power. I can't trace this past the fork because it
crashes so fast
I can't get the new ID to give to gdb. I sent this in about a

in my email address. The AIX host itself does not have incoming

Because I did not remember to add a domain name to my
email address in my original problem report, the name
of the AIX host from which I submitted the report was
added. That machine does not have incoming email, so
I never saw the message that Doug Engert sent me. Doug
sent it to me again today. Thanks!
