upstream see https://bugzilla.redhat.com/show_bug.cgi?id=1381997

openssh-7.4p1-1.el7 should fix it.

Thanks Tru.

Re: [CentOS] C 7.3 sshd will not reload

[Tate Belden]

Oh yea!

That's how I test/implement new configurations.

Make a change
restart
test
make a change
Lather, rinse and repeat

Did you actually change something before doing the restart? If nothing changes
it will restart every time. If I change the configuration to for instance have
sshd listen on another port, that is when I have the problem. Oh and selinux is
in permissive.

There is nothing special about the environment. a couple of VM's in question
are brand new minimal installs. I spin them up for testing push new sshd configs
to them with Ansible and tear them down.

Before someone says Ansible is the problem I have tried this by hand also.

restart, reload, stop then start all produce the same results.

If I do not change the configuration, and just issue the restart, reload,
etc.
then it behaves as expected. Obviously that is not useful when you have
configuration changes.

I tested this on a couple of other VM's and get the same results.

I have to assume it's something unique to your install, then.

I run about a dozen sshd instances on as many CentOS 7 boxes around here.
To a one, systemctl restart sshd is all it takes to implement config
changes.

Only time it's given me fits is if I forget to actually write the config
file in VIM. That pesky w gets me on rare occasion.

Might I suggest using "systemctl restart sshd", instead of reload? At the
least - see if it behaves differently for you.


   - *restart* = stop + start
   - *reload* = remain running + re-read configuration files.

[CentOS] C 7.3 sshd will not reload

[me]

Hi,

Since upgrading to 7.3 I am having a problem getting sshd to reload after
configuration changes. When I issue the command "systemctl reload sshd.service"

I get the following error: "Unit sshd.service cannot be reloaded because it is 
inactive."

It is obviously still running because I am connected over ssh to the machine 
and netstat
shows it is listening.
(vnewman pts3) # netstat -tulpn | grep ssh
tcp0  0 0.0.0.0:22  0.0.0.0:*   LISTEN  
29249/sshd
tcp0  0 127.0.0.1:6010  0.0.0.0:*   LISTEN  
3012/sshd: root@pts
(vnewman pts3) #

If I reboot the machine, then everything is OK.

Has anyone seen this behavior or more importantly know how to fix it?

Regards,
