[developer] Sshd fails on OS upgrade

[developer] Sshd fails on OS upgrade

[Gary Mills]

Yesterday, I upgraded one of my systems from hipster-20230813 to
hipster-20241104.  (The number is the ISO date with dashes removed).
On reboot, everything was successful, except the console said:

SUNW-MSG-ID: SMF-8000-YX, TYPE: defect, VER: 1, SEVERITY: major
EVENT-TIME: Mon Nov  4 16:55:50 CST 2024
PLATFORM: S5510, CSN: empty, HOSTNAME: tyan
SOURCE: software-diagnosis, REV: 0.1
EVENT-ID: 26a5e479-0755-47d0-837d-4a0fbb3f6e99
DESC: A service failed - a start, stop or refresh method failed.
  Refer to http://illumos.org/msg/SMF-8000-YX for more information.
AUTO-RESPONSE: The service has been placed into the maintenance state.
IMPACT: svc:/network/ssh:default is unavailable.
REC-ACTION: Run 'svcs -xv svc:/network/ssh:default' to determine the generic
+reason why the service failed, the location of any logfiles, and a list of
+other services impacted.

The server log said:

[ Nov  4 16:55:49 Executing start method ("/lib/svc/method/sshd start"). ]
/etc/ssh/sshd_config line 85: Deprecated option ServerKeyBits
/etc/ssh/sshd_config line 90: Deprecated option KeyRegenerationInterval
/etc/ssh/sshd_config: line 103: Bad configuration option: MaxAuthTriesLog
/etc/ssh/sshd_config line 132: Deprecated option RhostsAuthentication
/etc/ssh/sshd_config line 138: Deprecated option RhostsRSAAuthentication
/etc/ssh/sshd_config line 145: Deprecated option RSAAuthentication
/etc/ssh/sshd_config: terminating, 1 bad configuration options
[ Nov  4 16:55:49 Method "start" exited with status 95. ]

The configuration file was /etc/ssh/sshd_config .  When I edited that
file to comment out all the Deprecated or Bad options, the service ran
with no fatal errors.  I don't know where that file came from, but it
dates from 2017, and often mentions Oracle and Solaris.  Perhaps it
came with an earlier version of the ssh package.  The options
mentioned all were in the version 1 section.

In any case, the ssh package should include a working configuration
file, for ssh dummies like me.  That way, the service would run
without all those errors.  I don't even use ssh on that system.

This message suggests that only the ListenAddress option needed to be
changed.  That's certainly not the case for my problem.

Please read all the thread.  For example this:

Re: [developer] Sshd fails on OS upgrade

Hi Gary

This file gets delivered in a working state by the package but as soon 
as you edit it, it will never be touched again by the package system. We 
can only destroy everyones edits by removing preserve=true attribute 
from the file or have this situation happen,

A workaround would be

mv /etc/ssh/sshd_config /etc/ssh/sshd_config.bak; pkg fix

once the file is not there it is elegible for restore by IPS.

Hope this helps in the Future
Till

Oh, it's the opposite from what I assumed.  The config file is
included in the package, but it was not installed.  Changing the
attribute to "preserve=renamenew" would satisfy everybody, but might
require manual renames.  Changing it to "preserve=renameold" would be
better for me, but would cause trouble for other people.

FWIW, there are at least two other options:

  - only deliver new software that is compatible with the existing
    configuration file (patch software as needed)

  - deliver an SMF service that "upgrades" the configuration, where
    it is mechanically possible to do so, prior to starting the service

Ultimately this is an OpenIndiana-specific issue, though, as we no
longer deliver SSH in illumos itself.  Other distributions are
presumably making different decisions with respect to backwards
compatibility and upgrades, etc.


Cheers.

As those of us who lived through it will remember, the transition from
SunSSH
to OpenSSH in OmniOS was fun. I remember having to push out a specially
fixed
sshd_conf that worked (and satisfied our requirements) with the old and new
ssh,
and then we had to do it again.

https://omnios.org/info/sunssh.html

In Tribblix, I've traditionally unconditionally overwritten sshd_conf on
update, but
recently switched over to retaining a modified version. Time will tell
whether that
causes more problems than it solves.
