Hello,

Yesterday our SSH daemon stopped accepting connections; in SSHD.LOG I see the
following message:

Failed to get handed-off socket: errno 6

Anyone has an idea what to do?

Background: VMS-7.3-2, Multinet 5.2.
Two days before the problem I've installed VMS patches SYS-4.0 and LOADSS-1.0.
After a reboot SSH daemon worked for a while and then stopped.

Thanks! __Yehavi:

This means that SSHD_MASTER found a valid identification message, marked
its incoming socket for handoff to SSHD2, then spawned an SSHD2
process. The first thing SSHD2 does is to assign a socket to the one that
was marked for handoff. In the course of this, it received an error
indication, saying the socket is no longer available. I recommend you
restart SSH, then examine MULTINET:SSHD_MASTER.LOG to see if it says
anything about why the socket went away. Do you have the latest SSH ECO?

I have seen the same problem but under OpenVMS version 8.3 after installing
the VMS83A_SYS-V0400 ECO released October 31. Removing the VMS83A_SYS-V0400
ECO got rid of the problem. I notice that a VMS83A_SYS-V0500 ECO has since
been released on November 5; however, as the ECO release notes say the V0500
version was released to address an issue in the replacement of the HELPLIB
library, I would expect that VMS83A_SYS-V0500 has the same issue with
the MultiNET SSHD_MASTER as VMS83A_SYS-V0400.

That's an option, and I have been on forum site early on. However, I
have a strong personal preference for e-mail in support situations.
That's mostly because e-mail things land in my lap instead of my having
to initiate a connection on a website.

No, the forums are another way for people to communicate who find the web
their preferred mode. They are meant to be an addition to the lists and
not a replacement
