I’m “happy” to say that I experienced this on a server—not having ssh access to a remote server is fairly annoying, I definitely sympathize… What I see is this: --8<---------------cut here---------------start------------->8--- Aug 6 07:56:40 localhost shepherd[1]: Service loopback has been started. [...] Aug 6 07:56:51 localhost sshd[606]: Server listening on 0.0.0.0 port 22. [...] Aug 6 07:57:05 localhost shepherd[1]: Service ssh-daemon could not be started. [...] Aug 6 07:57:46 localhost vmunix: [ 10.049791] random: ssh-keygen: uninitialized urandom read (32 bytes read) --8<---------------cut here---------------end--------------->8--- (Note that the last message was pulled from /dev/kmsg by syslogd, but it’s about an event that actually occurred before the first message.) It waited for ~15 seconds, although ‘%pid-file-timeout’ in (shepherd service) is only 5 seconds. The SIGTERM you were seeing very likely comes from this bit: --8<---------------cut here---------------start------------->8--- (match (read-pid-file pid-file #:max-delay pid-file-timeout) (#f (catch-system-error (kill pid SIGTERM)) #f) ((? integer? pid) pid)) --8<---------------cut here---------------end--------------->8--- On another machine: --8<---------------cut here---------------start------------->8--- Aug 28 09:10:49 localhost sshd[435]: Server listening on 0.0.0.0 port 22. Aug 28 09:10:49 localhost sshd[435]: Server listening on :: port 22. [...] Aug 28 09:10:50 localhost shepherd[1]: Service ssh-daemon has been started. --8<---------------cut here---------------end--------------->8--- I wonder if this has to do with IPv6 (the failing case lacks the “Server listening on ::” line), or if it’s just sshd occasionally taking a long time to start. Is it easily reproducible for you? Did you eventually gather more details? Thanks, Ludo’.
