On trixie who (GNU coreutils 9.5) gives me a long list of logins, most
of which predate the most recent reboot. "who -u", similarly.
who version 9.4 on armbian does not suffer from either of these
problems. 9.1 on bookworm would seem to be a bit elderly.
However 9.1 on an rpi4 running bookworm in aarch64 works well.
Some of my cnc machines are still on wheezy, where version 8.3 also
works properly. You and I have 9.1 which acts as you say.
How do I get only the current logins?
Also, who on bookworm works fine with no arguments. who on bookworm
requires the file to use in order to get any useful output at all,
e.g.: "who -Hu /var/log/wtmp". This might be a bug.
That gives the history since the last install, but does not do the src
address lookup, so IMO its not a perms problem.
Finally, I see that bug #798910, "coreutils: /usr/bin/who --lookup does
not look up ip addresses in dns", is still outstanding and a bit
annoying. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=798910
Thank you.
