[gentoo-user] New openssh install message?

[gentoo-user] New openssh install message?

[Mark Knecht]

Hi,
   I don't remember seeing this message on previous openssh updates:

>>> Installing (1 of 1) net-misc/openssh-5.3_p1-r1
 * >>> SetUID: [chmod go-r] /usr/lib64/misc/ssh-keysign ...
              [ ok ]
 * Remember to merge your config files in /etc/ssh/ and then
 * reload sshd: '/etc/init.d/sshd reload'.

   Is this a new message or have I just missed in the past? I don't
know anywhere else for ssh configuration files to exist except
/etc/ssh and I normally just do

/etc/init.d/sshd restart

anytime it gets updated.

   Has anything changed about this? I'm updating a remote machine and
don't want to lose connectivity.

Thanks,
Mark

Probably what the writer of that message meant is to update the config 
files with dispatch-conf and the like.  I don't know to what else 
"merge" could refer.

Thanks. OK, so I did a restart and I can still ssh in so things seem OK.

Sometimes the international as[ect of Linux add extra confusion. I'm
sure it's perfectly clear to someone.

Cheers,
Mark

With a remote machine, I always restart SSH, leave the current shell open
and open a new one from another terminal. The old session will continue
to work when you shut down sshd, so if the new install is somehow broken,
you still have the access you need to fix it.

Thanks Neil. That's exactly what I did, additionally logging in as a
different user that wasn't present before the restart.

Cheers,
Mark

A restart is just a showdown followed by a start. I wrote shut down
because even if the restart fails and you have no sshd running, your
existing ssh session will continue to work while you fix the breakage.

noobs shouldn't be administering Gentoo boxes remotely :P

The severity of the itch is inversely proportional to the reach.

The message isn't new; every version of openssh in portage includes it
as part of the post-install.

As far as I can determine, it's just a reminder to restart ssh after
merging your config changes e.g. with conf-update or whatever you use,
so you can take advantage of whatever security bugfixes were present in
the new version.
