If /etc/sysconfig/rhn/rhnsd isn’t there then either rhnsd hasn’t installed correctly or, like you say, someone or something has removed it afterwards. If that’s the case may be other related files could be missing too? Either way if you verify the package (rpm -V rhnsd) it should give you some indication of this. If it does find errors then yes, initially, just try re-installing it.

Might be wise to check the other packages, that were installed for client registration, too:

rhn-client-tools
rhn-check
rhn-setup
m2crypto
yum-rhn-plugin

Phil

If /etc/sysconfig/rhn/rhnsd is not there, then need to investigate the package rhnsd. I would try and reinstall the rpm, and check to see if the file is there.

If the file is not there:
        What version of rhnsd is installed on the clients?
        What files are being provided by the rpm?  rpm -ql rhnsd

If the file is there:
        Wait..... If it is no longer there after some time.
        A mis-configured chef/puppet/automated action could be deleting the file vs creating or updating the file.


If it is still there, some other items to look at:
        Someone could have accidentally deleted the file (oops).
        There could a custom RPM that is being installed on the impacted systems that has a script which is deleting the file.

Thanks

Phil,

Still a problem with the offline clients.
It looks like that the rhn daemon stops working after some time.

Redirecting to /bin/systemctl status  rhnsd.service
● rhnsd.service - Spacewalk Server daemon
   Loaded: loaded (/usr/lib/systemd/system/rhnsd.service; static; vendor preset: disabled)
   Active: inactive (dead)



And some more:

I have no /etc/sysconfig/rhn/rhnsd

[root at vie-srv-XXX log]# cd /etc/sysconfig/rhn/
[root at vie-srv-XXX rhn]# ls -la
total 24

In the rhncfg-client.conf I can find a log directory: script_log_file = /var/log/rhn/rhncfg-action-output.log

But even this log file does not exist……


Warm regards,

Harald

No problem Harald. If you want to continue using rhnsd you can still reduce the check-in time in /etc/sysconfig/rhn/rhnsd if you want though (default is 240 mins):

# cat /etc/sysconfig/rhn/rhnsd
INTERVAL=240
#

Hi Phil,

Thanks for your reply.
It looks like it was a rookie mistake.
I am new at Spacewalk and I followed the instructions here to register a client.

https://github.com/spacewalkproject/spacewalk/wiki/RegisteringClients

Unfortunately there was no hint that you have to start the rhnsd service.
So I have started the service now and configured it to start automatically.
And I need no osad at the moment. Every 4 hours check in is fine for me.

Thanks again,

Warm regards,

Harald

Hi Harald

Were they ok originally, and stopped working properly, or are you just trying to setup OSAD for the first time? Either way if you work through my personal notes (for OSAD), below, it may help to identify your problem. If everything has been done correctly it may be an infrastructure problem though ie un-reliable network connection or NTP?

By default, the rhnsd daemon on a client system connects to the Spacewalk server every four hours (see /etc/sysconfig/rhn/rhnsd) and performs any updates or actions that have been scheduled. If you install the OSA daemon, you can apply updates and actions to client systems immediately from the Spacewalk server.

osa-dispatcher
Server-side service that determines when an osad client instance needs to be pinged or run rhn_check and sends a message telling them to do so. This is installed when Spacewalk is installed.

Open Source Architecture Daemon (OSAD)
Client-side service that responds to pings and runs rhn_check when told to by osa-dispatcher.

See official documentation, at the following link, for more details:

https://github.com/spacewalkproject/spacewalk/wiki/OSADSetup

Install OSAD and related RHN/Spacewalk packages
# yum -y install osad rhncfg rhncfg-actions rhncfg-client

Spacewalk Actions Control - Enable Scheduled Actions
# rhn-actions-control --enable-all

Spacewalk Actions Control - Show Status
# rhn-actions-control --report

Start OSAD
# systemctl start osad.service OR service osad start

Enable OSAD
# systemctl enable osad.service OR chkconfig osad on

OSAD Log File
/var/log/osad


Hope this is of help
Phil

Hi, Jonathan,

Looks good:

[root at vie-srv-log02 ~]# netstat -tn|grep 5222
tcp        0      0 172.21.0.181:46018      172.21.0.166:5222       ESTABLISHED


Nerveless the client is offline in spacewalk.

Warm regards,

Harald

all your clients should have established traffic to the spacewalk server on port 5222.  it should stay in an established state.

[jhorne at dlp-log01 ~]$ netstat -tn|grep 5222

Hi  all,

I have the problem that most of my systems (CentOS 6 & 7) are going offline after approximately one day.
Only if I run rhn_check the systems come online again, but only for short time.

I have tried to install osad service, the service is running but nerveless the client is going offline.

Any help would be very appreciated.


Best regards,

Harald
