SSH Last login: (and lastlog, too)

SSH Last login: (and lastlog, too)

[Achim Gratz]

For some time now (it had been working at least around March this year)
SSH tells me that I've last logged in from whatever IP instead of the
name of the machine.  Lastlog does the same.  Name resolution works just
fine as you can see when running ssh with debug on and it will check the
correct known_hosts line for the name.  Is there some setting I need to
change to make this work again?


Regards,
Achim.

I'm wondering if the default value for UseDNS in /etc/sshd_config
changed.  It used to be 'yes' (and still is for the official
distribution) but many were pushing it to be 'no' (I think CentOS now
defaults this to 'no').

Try setting "UseDNS" to "yes" in /etc/sshd_config, restarting your
sshd process, log in/out a few times and see if that fixes the issue.

Thanks a bunch, I would't have found this!  That's exactly what has been
causing the issue.  So I'll change all sshd_config files…

Good catch.  However, this is nothing Cygwin sets differently than
upstream.  Except for two settings (StrictModes, UsePrivilegeSeparation)
Cygwin defaults to the upstream settings.
