Package: dynamic-motd Version: 0.04-1 Severity: normal Before installing dynamic-motd, (key-based) "ssh root@localhost" was more or less instantaneous (below 1 second).
Since installing dynamic-motd it takes about 40 seconds to login on that box, even via localhost and even despite being a not so slow box (a quad-core workstation with a single X session and lot of xterms and outgoing SSH sessions): ~ → lscpu | fgrep "Model name"; uptime; date; ssh localhost date Model name: Intel(R) Core(TM) i7-6700T CPU @ 2.80GHz 02:34:23 up 55 days, 7:39, 196 users, load average: 3.09, 3.52, 3.28 Fri Jun 10 02:34:23 CEST 2022 Fri Jun 10 02:35:05 CEST 2022 ~ → Most time seems to be spent for calling checkrestart (33 seconds). If only needrestart would have been installed, that step would even have taken even longer (4 minutes and 18 seconds; phew!) So please try to at least cache the results of checkrestart and needrestart. Or maybe pre-calculate them via cron-job once an hour or so. Or disable them completely by default. For those suffering from this issue as well, here's how I solved it for myself: # dpkg-divert --local --rename --divert /etc/update-motd.d/50-services-need-restart.DISABLED --add /etc/update-motd.d/50-services-need-restart Now I'm down to about 8 seconds for logging in via SSH. -- System Information: Debian Release: bookworm/sid APT prefers unstable APT policy: (990, 'unstable'), (600, 'testing'), (500, 'unstable-debug'), (500, 'buildd-unstable'), (110, 'experimental'), (1, 'experimental-debug'), (1, 'buildd-experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.16.0-6-amd64 (SMP w/8 CPU threads; PREEMPT) Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) LSM: AppArmor: enabled Versions of packages dynamic-motd depends on: ii bc 1.07.1-3+b1 ii figlet 2.2.5-3+b1 ii lsb-release 11.2 ii python3 3.10.4-1+b1 ii python3-utmp 0.9-1+b5 dynamic-motd recommends no packages. dynamic-motd suggests no packages. -- no debconf information
