Solved Howto autostart ssh
-
I can´t solve the autostart service for the ssh server.
I use OTA24 with second OS of VollaPhone22.I startet the ssh server:
$sudo service ssh start $sudo systemctl is-enabled ssh enabledChecking for service to start on boot:
$systemctl is-active ssh inactiveTo enable the service to start on boot, I gone to:
$sudo systemctl enable ssh Synchronizing state of ssh.service with SysV init with /lib/systemd/systemd-sysv-install... Executing /lib/systemd/systemd-sysv-install enable ssh update-rc.d: error: Device or resource busyMy solution to read/write to root files:
1.) Open UT Tweak Tool
2.) go to System => make image writable => Temporary$sudo mount -o remount,rw /But no change:
$sudo systemctl enable ssh Synchronizing state of ssh.service with SysV init with /lib/systemd/systemd-sysv-install... Executing /lib/systemd/systemd-sysv-install enable ssh update-rc.d: error: Device or resource busyHow can I enable ssh service on start?

systemctl enable sshmeans to start the service at boot time. So if you reboot the phone after entering that the ssh server daemon would start.But, you don't have restart the phone to start the ssh server daemon, you can just enter
systemctl start sshIf you want to do that in one step you can enter
systemctl enable --now ssh -

Thanks, but the service is not starting on boot. The service is not stored in update-rc.d because the error is:
update-rc.d: error: Device or resource busyIs there a other solution or way to get access to the update-rc.d ?

Sorry, I for some reason thought you were on 20.04. I'm surprised that systemctl commands work on 16.04 which uses upstart hence the service command.Is something else using the port 22? Does the netstat command work? - I don't have quick access to a Ubuntu Touch install at the moment so I don't know if that command is available.

Yes, I use the VollaPhone22 with Ubuntu 16.04 (OTA-24).
In the next days, I get my new phone Pixel 3a. I go to install 20.04 and try this with my new phone. Maybe this is a issue with the port of VollaPhone22?
Thanks, I report then here my experience! -

You can ask here : https://github.com/HelloVolla/ubuntu-touch-beta-tests/issues

The same on Pixel 3a (OTA24)
$sudo systemctl enable ssh Synchronizing state of ssh.service with SysV init with /lib/systemd/systemd-sysv-install... Executing /lib/systemd/systemd-sysv-install enable ssh update-rc.d: error: Device or resource busyWhy is device or resource busy?

In the user guide about how to start ssh for 16.04, there is nothing about the
systemctlcommand. I don't recall to use such command when enabled ssh on my FP2 a long time ago (it works after reboots). Does Vollaphone handle it differently? -
@jezek
Yes, this is correct, there is nothing aboutsystemctl.
Enabled ssh is after reboot disabled on VollaPhone, same on Pixel 3a with 20.04 (2022-W51).
Is there a solution to turn ssh service on, while booting? -

Hmm... if there is
systemctl, then there has to besystemd, am I right? And if there is a systemd, then you can write a user service, which will run at boot.If there is no
systemd, then it is using upstart and you can make it run script on boot.If everything fails try cron job on boot.

@jezek
Thanks for the explanation.
I've now read deeper and found the command for ssh in runlevel3.
This points to /etc/init.d. This is the script that starts the "OpenBSD Secure Shell server" at boot time.
According to my research, the settings for the autostart are made in /etc/init.
Since I don't want to change the script, but just want to start the service, I've included
sudo update-rc.d ssh defaultsenabled the shh service (again).
After that I got this output with the following command:phablet@ubuntu-phablet:~$ service --status-all ... [ + ] apparmor [ + ] isc-dhcp-server [ - ] keyboard setup ... [ + ] network manager [ + ] networking ... [ - ] rc.local ... [ + ] ssh [ + ] udev ...Although ssh is shown as an active here, I can't access UbuntuTouch 16.04 from my client.
ssh: connect to host 192.168.188.50 port 22: Connection refusedIn the systemctl I found the ssh.socket with the following command. However, this ssh.socket is not executable.
$systemctl list-unit-files --type=socket UNIT FILE STATE ... ssh.socket enabled ... systemd-networkd.socket disabled ...I need to run the
sudo service ssh startcommand manually to get access via ssh.I found the startup script for ssh.service under /lib/systemd/system and it already exists.
When I run the existing ssh.service command to enable it, I get the following error:root@ubuntu-phablet:/lib/systemd/system# systemctl enable ssh.service Synchronizing state of ssh.service with SysV init with /lib/systemd/systemd-sysv-install... Executing /lib/systemd/systemd-sysv-install enable ssh update-rc.d: error: Device or resource busy root@ubuntu-phablet:/lib/systemd/system# systemctl status ssh Failed to get properties: No such interface ''I see the problem in the following line:
update-rc.d: error: Device or resource busyIs this service locked in UbuntuTouch?
After the reboot I still getssh stop/waitingfromsudo status ssh. Am I missing something here?
A manualsudo service ssh startresults inssh start/running, process 7838.
Can someone confirm that the ssh service doesn't start automatically?I'll try it now with cron job on boot, hopefully it works. But it's not such a clean solution.

@chris_bavaria I have an FP2. I've enabled ssh long time ago, using the documentation mentioned above. The only trouble I have with ssh, is that when I enable wifi on the phone and want to connect to it (from notbook using ssh), many times the connection doesn't get through. I have to reconnect the wifi on the phone (by tapping on the connected wifi name in wifi notification area) and than it connects. No need to start service in the phone terminal.

@jezek
Is ssh automatically activated when the phone starts? -
Hi, it's probably a botched job. I'm sorry.
SSH does not start automatically on Pinephone and Vollaphone 22. It may happen on more devices, I don't know.
To solve it I created this "thing" when I played with Pinephone.
Script enabledSSH.sh
#!/bin/bash ### Enable SSH at startup in UT ### echo "#!/bin/bash" > startssh.sh echo "### Iniciar SSH ###" >> startssh.sh echo "exec service ssh start" >> startssh.sh sudo chmod +x startssh.sh sudo mount -o remount,rw / sudo cp startssh.sh /etc/init.d/ sudo rm startssh.sh sudo update-rc.d startssh.sh defaults sudo rebootThen execute:
bash enabledSSH.shP.S. Rerun only when changing channels.

@bolly
THANK YOU SO MUCH !
Now runs after a reboot and is also available without unlocking the home screen.
This is a real work simplification.Great work!
