Ominous mm_request_send since install of HP-UX Secure Shell-A.04.00.000

[Ralph Grothe]

Dear Forumers,

seems it was a bit too daring having had installed the latest HP-UX Secure Shell and expecting the upgrade to integrate as seamless as being used to hithero.

I installed this depot
T1471AA_A.04.00.000_HP-UX_B.11.00_32+64.depot
which I got from
http://h20293.www2.hp.com/portal/swdepot/displayProductsList.do?category=ISS
and that installed this port of OpenSSH:

[root@terra:/etc/ssh]
# /opt/ssh/sbin/sshd -v 2>&1|head -3
sshd: illegal option -- v
OpenSSH_4.1, OpenSSL 0.9.7e 25 Oct 2004
HP-UX Secure Shell-A.04.00.000, HP-UX Secure Shell version

Having moved the hostkeys that got created by the depot's postinstall out of place and having restored the former ones, I simply sent a SIGHUP to sshd.

Now whenever I connect from a remote client who has the public hostkey in its known_hosts,
and who has the remote account's public RSA/DSA keys deposited in the login account's authorized_keys,
I can see that the connection gets immediately closed by the sshd (using triple verbosity).

What puzzles me is the following entry written in the sshd's host's syslog.log:

[root@terra:/etc/ssh]
# tail -3 /var/adm/syslog/syslog.log
Sep 13 13:33:22 terra sshd[12434]: fatal: mm_request_send: write
Sep 13 13:33:41 terra sshd[12494]: fatal: mm_request_send: write
Sep 13 13:53:41 terra sshd[13392]: fatal: mm_request_send: write


I am clueless about the mm_request_send call.
I've never come accross these messages.
Has anybody heard or read about, and knows a fix, work-around or patch?

Regards
Ralph

I have got the same message, after setting a passwd ssh/keys where working.

Hi Frank,

I know, I fixed that soon after having posted by filling the passwd hash field in /etc/passwd of the user with an exclamation point ("!").

Oops, sorry meant address it to Freek
but somehow typed Frank.
