Re: [yocto] #yocto systemd not able to start sshd after a reboot
Maybe this should be added to sshd.service [unit] part (to have added dependency) to solve this problem: > The sshd.service file is as follows: > [Unit] > Description=OpenSSH server daemon > Documentation=man:sshd(8) man:sshd_config(5) > After=sshdgenkeys.service > Wants=sshdgenkeys.service *Requires=**sshd.socket* Zoran ___ On Fri, Sep 18, 2020 at 5:29 PM wrote: > > I am facing a peculiar problem with openssh.

Re: [yocto] #yocto systemd not able to start sshd after a reboot
Seems strange to me too...I had been troubleshooting the sshd.service issue for two days. There was no logs, nothing. I was just hitting the wall. I tried a lot of combinations to get it to work but all failed. The sshd.service was starting, if I manually did a systemctl start sshd.service. But always failed at startup. At times it would start and then get a signal 15 terminating and would close the daemon. After not able to resolve the issue, I started checking all the other services. Every other service was starting at bootup just fine except sshd. Not finding anything else to troubleshoot. I happened to stumble upon the sshd.socket and the Conflicts part of it. Did a hit and trial and it worked. Technically I still am not sure as to why.. -=Srijan Nandi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

There is no formal dependency between sshd.service and sshd.socket! [vuser@fedora32-ssd systemd]$ systemctl list-dependencies sshd.service | grep ssh sshd.service ● ├─sshd-keygen.target ● │ ├─sshd-keygen@ecdsa.service ● │ ├─sshd-keygen@ed25519.service ● │ └─sshd-keygen@rsa.service [vuser@fedora32-ssd systemd]$ systemctl list-dependencies sshd.service | grep socket ● ├─lvm2-lvmetad.socket ● ├─lvm2-lvmpolld.socket [vuser@fedora32-ssd systemd]$ systemctl list-dependencies sshd.socket | grep sshd sshd.socket Strange... Isn't it?!

Re: [yocto] #yocto systemd not able to start sshd after a reboot
> > Seems that some leftovers from System V still reside in YOCTO... > Correct??? > Not sure about that. The problem I faced was because there was a sshd.socket that had the following line in it. The sshd.socket comes with openssh. Conflicts=sshd.service So I had two options. either to add the ExecStartPre in the sshd.service file or to remove the Conflicts line in sshd.socket. I choose to remove the Conflicts line and add the following in the sshd.socket file. After=network.target Before=sshd.service Thanks and Regards, -=Srijan Nandi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [yocto] #yocto systemd not able to start sshd after a reboot
Hello All, I finally got it to work!!! There was a sshd.socket file in /lib/systemd/system which had the following line in it. Conflicts=sshd.service I remove it and added the following two lines: After=network.target Before=sshd.service And that did the trick. Now sshd service starts on every boot.

Hello Khem, With the above sshd.service file the sshd daemon fails to start. It gives an error "(code=exited, status=203/EXEC)". Cannot figure out as to why the systemd for sshd fails to work, while the other systemd files are working perfectly fine. -=Srijan Nandi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[yocto] #yocto systemd not able to start sshd after a reboot
I am facing a peculiar problem with openssh. I have built openssh_8.0p1on zeus. The sshd.service file is as follows: [Unit] Description=OpenSSH server daemon Documentation=man:sshd(8) man:sshd_config(5) After=sshdgenkeys.service Wants=sshdgenkeys.service [Service] Type=simple PIDFile=/var/run/sshd.pid EnvironmentFile=-/etc/default/sshd ExecStart=/usr/sbin/sshd -D $OPTIONS ExecReload=/bin/kill -HUP $MAINPID ExecStop=/bin/kill $MAINPID PermissionsStartOnly=true KillMode=process Restart=on-failure StandardError=syslog [Install] WantedBy=multi-user.target It starts without issues, if i do a systemctl start sshd.service. If I do a test of the config file it does not come up with any errors: genericx86-64:~$ sudo /usr/sbin/sshd -t genericx86-64:~$ Problem: If I reboot the server, sshd does not start. There is no error on syslog. I have enabled debug logging, still no logs in syslog. # Logging SyslogFacility DAEMON LogLevel DEBUG3 Even systemctl is-enabled sshd shows as enabled. After a reboot, if I do a systemctl status sshd it shows: Loaded: loaded (/lib/systemd/system/sshd.service; enabled; vendor preset: enabled) Active: inactive (dead) If I manually run systemctl start sshd.service, everything works perfectly well without issues. sshd start on 0.0.0.0:2224 and I am able to ssh in as well. It's just that systemctl is not able to start sshd after a reboot and there is no error that i can find or debug. Absolutely run out of ideas to resolve this. Any help will be greatly appreciated.
