systemctl does not list units

Hello everyone,
On my x86 headless Arch Linux server, that I recently updated to try and fix the issue, I am having the following problem:
When using "systemctl list-units" or just "systemctl" I get the following message:

"Failed to list units: Message recipient disconnected from message bus without replying"

Searching for this results in no google matches.

Any advice on what to do?
Thanks for you time.

Funny, when I search for that error message quoted and adding 'systemctl' I get countless results, many of them even seem directly relevant, like this one:
https://github.com/systemd/systemd/issues/2925

Are you ssh'ing into this system (or are others ssh'ing into it)?  What does `loginctl list-sessions` return?

Only this post shows up for me, don't know why.

Sadly the link you provided doesn't really clear anything up for me. It says that the problem is fixed?

Yes I am SSHing into the server.

loginctl lists my user 16 times.
Any more advice?
Thanks again!

Please read the CoC (particularly the section regarding images), and do not post giant images again.

Figure out why you are logged in 16 times.  That doesn't sound like so many that I'd excepted it to be a problem, but it is 15 more than there should be.

Re: systemctl does not list units

I have been investigating and one session is running the tmux process which is okay, I guess. And the other ones all look like this:

 loginctl session-status 4
4 - myuser (1000)
           Since: Sun 2018-09-09 23:09:47 CEST; 1 weeks 2 days a>          Leader: 6615
          Remote: 192.168.2.23
         Service: sshd; type tty; class user
           State: closing
            Unit: session-4.scope
lines 1-7/7 (END)

I am wondering about the "closing" state.
"loginctl terminate-session" doesn't work. The session stays alive without an error message.

Googling only leads to old bugreports that have been closed by now.

Re: systemctl does not list units

Wonky network?
Do you S3 the client while the ssh connection is active?
Can you inspect the servers ssh log?
Can you terminate/kill those sessions?
How does their presence evolve over time?

Nothing that I am aware of, network seems to work fine.

seth wrote:

I S4 my client. I have also done that while the connection was still active, yes. I am also usually connected to tmux while doing so.

seth wrote:

The log is completely flooded by brute force login attempts from the internet on my server.

This is what I tried:

$ loginctl session-status 16
16 - myuser (1000)
           Since: Tue 2018-09-18 15:49:10 CEST; 1 day 2h ago
          Leader: 14610
          Remote: 192.168.2.23
         Service: sshd; type tty; class user
           State: closing
            Unit: session-16.scope

Sep 18 18:07:59 homeserver sshd[14667]: Timeout, client not responding from user myuser 192.168.2.23 port 53567

$ loginctl kill-session 16
Could not kill session: No such file or directory

$ loginctl terminate-session 16

$ loginctl session-status 16
16 - myuser (1000)
           Since: Tue 2018-09-18 15:49:10 CEST; 1 day 2h ago
          Leader: 14610
          Remote: 192.168.2.23
         Service: sshd; type tty; class user
           State: closing
            Unit: session-16.scope

Sep 18 18:07:59 homeserver sshd[14667]: Timeout, client not responding from user myuser 192.168.2.23 port 53567

As you can see, it didn't do anything.
What is going on there?

seth wrote:

The sessions stay the way they are, and only when i connect again, another one is added. It also seems that even proper disconnection doesn't make sure the session is removed.
I disconnected from session 17 by typing "exit", but still the session lingers:

]$ loginctl session-status 17
17 - myuser (1000)
           Since: Tue 2018-09-18 20:14:15 CEST; 22h ago
          Leader: 11711
          Remote: 31.16.253.24
         Service: sshd; type tty; class user
           State: closing
            Unit: session-17.scope

Sep 19 09:05:51 homeserver sshd[11711]: pam_unix(sshd:session): session closed for user myuser

I am pretty lost right now.

Do you allow password logins?  If so, the most parsimonious explanation may be that some of those attempts have been successful.

Do you have tmux set to reconnect to the existing session rather than just creating a new one?

Nope, I don't.

I don't exactly know what that means. After I connect to the server, I call "tmux a". This connects me to existing tmux sessions, but I believe that is a different kind of session.

What might the connection between the stuck sessions and the systemd error be?

Re: systemctl does not list units

Do the S4 naps relate to the timeout errors in the session statūs?

Let's see "ps fax" (you may redact the porn urls in your browser processes, we care about shell etc. which could inhibit a session termination)
Did you maybe fumble around w/ systemd because of something related to https://github.com/tmux/tmux/issues/428 ?

I  pretty sure they do. But I also see that not only the s4 timeouts cause this. I logged out of one session with my smartphone properly by typing exit and wasn't even using tmux and I still got a stuck session.
