After a recent update sshd.service would not load at boot but would manually start. Based on web articles it was hanged to sshd.socket
systemctl disable sshd.service
added a file
/etc/systemd/system/sshd.socket.d/10-sshd-listen-ports.conf
with the following
[Socket]
systemctl disable sshd.service
added a file
/etc/systemd/system/sshd.socket.d/10-sshd-listen-ports.conf
with the following
[Socket]
ListenStream=
ListenStream=192.168.0.3:22
FreeBind=true
Run
# systemctl enable sshd.socket
# systemctl start sshd.socket
If the file is modified then run
# systemctl daemon-reload
# systemctl status sshd.socket
the result is:
sshd.socket - OpenSSH Server Socket
