Dead sshd.socket after vpn disconnect in NetworkManager

Hello Guys

When i disconnect from any type of VPN in Network Manager my sshd service stopped.
Here are few logs:

I tried sshd.service and sshd.socket. Both stopped after vpn disconnect

# systemctl status sshd.socket
● sshd.socket
   Loaded: loaded (/usr/lib/systemd/system/sshd.socket; enabled; vendor preset: disabled)

Sep 26 19:35:15 localhost.localdomain systemd[1]: Listening on sshd.socket.
Sep 26 19:59:36 localhost.localdomain systemd[1]: Closed sshd.socket.

cat /etc/systemd/system/sockets.target.wants/sshd.socket

[Unit]
Conflicts=sshd.service
Wants=sshdgenkeys.service

[Socket]
ListenStream=22
Accept=yes

[Install]
WantedBy=sockets.target

Here is the content of /usr/lib/systemd/system/sshd.service.  It has "Restart=always" and i supposed that it should help to keep sshd online all the time.

[Unit]
Description=OpenSSH Daemon
Wants=sshdgenkeys.service
After=sshdgenkeys.service
After=network.target

[Service]
ExecStart=/usr/bin/sshd -D
ExecReload=/bin/kill -HUP $MAINPID
KillMode=process
Restart=always

[Install]
WantedBy=multi-user.target

Is there some special configuration for sshd service & NetworkManager?

Re: Dead sshd.socket after vpn disconnect in NetworkManager

Not sure if this is relevant but you need to set your hostname, not doing so can cause all sorts of issues.

Also can you please use code tags instead of quote tags.

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Re: Dead sshd.socket after vpn disconnect in NetworkManager

slithery,
Thank you for the reply.

I've set hostname and restarted my PC. But it did not help.

[root@workhost ~]# hostname
workhost
[root@workhost ~]# ping workhost
PING workhost (127.0.0.1) 56(84) bytes of data.
64 bytes from workhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.053 ms

of course I can install monit to watch for the sshd process and restart it....

But i still hope there should be right way to resolve that issue.
