Where can i find logs?

Get Started

I’m trying to set up my new Jolla2026 and experienced some problems. Most were because i didn’t pay attention and i could solve them. but there is one atm that leaves me puzzled.

I managed to set up passwordless login for ssh via keys. it worked until it didn’t anymore. all of a sudden when i was about to copy data to the phone via rsync i was asked for a password again. i seriously can’t say what has caused this sudden change and now i’m trying to debug it. but i cannot find logs. journalctl says nothing about ssh or logins.

so if anybody could point me into a direction where i can find infos about logins and ssh within sailfish os i’d be very glad!

thanks in advance

You need to enable persistent logs:

Thanks, i had seen this before. but there i have the question: if nothing about logins and ssh shows up in the journalctl, what will be written about it into the persistent logs?

I understood that you didn’t get any logs at all.

You can increase the log level of sshd by increasing the LogLevel in the sshd config.

I’d honestly start out logging on the client side first, unless you already have.
What does a ssh-copy-id do?

As others said, you should start with using -v or even -vvv cli options first.

About journalctl, if you don’t use it with devel-su you still might not see very much.

Also you probably should reboot your phone after enabling persistent logging.

just fyi: i managed to start the sshd service and the status there showed me my errors with ssh. i’m still missing something like an auth.log … but that might be for later.

thanks to all for their advice! :slight_smile:

This shouldn’t be necessary since SSH is socket-activated on SfOS.

but without starting it i couldn’t see any logs or reports of what was happening. as i mentionend i found nothing like the auth.log in sailfish os

It’s fine to do so for debugging.

Did you enable persistent logging? After that sth like devel-su journalctl should give you some insights. And yes, I understand you might need to temporarily start sshd manually to get there.
