Hi Mike,
I believe that this was fixed with last update after bz1213423. Can you reproduce this issue? What were the steps that lead you to this failure?
Is possible that you were running server/session from older openssh version?

I could not reproduce it on Fedora-Live-Workstation-x86_64-22-TC3.iso
anymore. Although TC3 still has the same version of openssh-server
as the Beta Version of Fedora 22 where I encountered that problem:

[mfabian@Fedora-Live-Workstation-x86_64-2 ~]$ rpm -q openssh-server
openssh-server-6.8p1-5.fc22.x86_64
[mfabian@Fedora-Live-Workstation-x86_64-2 ~]$

I didn’t do any special steps to get that failure, after installation
of a beta version of Fedora 22 I just enabled ssh using

    sudo systemctl enable sshd.service
    sudo systemctl start sshd.service

then logged into the guest from the host using ssh.

Comment 15 Jakub Jelen 2015-05-18 07:02:04 UTC
If I am right, sshd is one of the services that are enabled by default (if not on workstation, please correct me. It doesn't mean that they are automatically installed) and I think this happened just during update of this package, when the old sshd was stopping and new version was starting (which is handled by systemd scriptlet).

I'm not aware that some of "enable" or "start" systemctl commands are doing restart if service is running so it seems strange to me.

According to FAF, there seems to be more people involved and also both versions 6.8p1-4.fc22 and 6.8p1-5.fc22 which supports my theory. I guess this should be reported for the first mentioned version and it looks like a bug in abrt for me. If nobody will protest, I will reassign it to abrt. They can maybe explain more.

No, sshd is not enabled by default after a default install from a
Fedora 22 Workstation Live DVD.

Comment 17 Jakub Jelen 2015-07-15 06:55:47 UTC
According to FAF, the reports no longer appears so I think it was really the rest of previous bug during service stop.
Closing.
