Description of problem:

Goferd on client system prints syslog messages into pts/tty sessions.
We received a lot of complaints from our users.

Description : Provides plugin for gofer, which allows communicating with Katello server
            : and execute scheduled actions.


Expected results:
Goferd should not spam pts/tty sessions.

Additional info:
As a workaround, I tried editing goferd configuration /etc/gofer/agent.conf to only log critical events (since the events logged have INFO severity) but apparently it was simply ignored (which is probably a bug too).

There is a bug related to this that affects older versions of RHEL. Are you using an older version of RHEL 6?

Comment 2 yohan.bataille 2016-11-30 09:05:32 UTC

Hello,
We are using RHEL 6.4. I tried to find the bug you are referring to but failed. Can you paste me the link ?

We just started using Satellite and encountered this issue. It will take time and lots of tests to update our servers to a newer version of RHEL6.
Maybe we can just update the package(s) that contain the fix ? Is it gofer and/or katello-agent ?

Thanks.

Comment 6 Craig Donnelly 2017-03-27 22:42:24 UTC

For those wondering, an update of python + python-libs corrects this issue, from the versions that are shipped with RHEL 6.4.

The version of python/python-libs with the fix is:

 python-2.6.6-51.el6
 python-libs-2.6.6-51.el6

These were shipped with RHEL 6.5 GA, it would appear. Update these packages, restart rsyslog + goferd, notice there will be no messages to stdout.

The changelog that corrected the issue:

* Thu Jul 04 2013 Matej Stuchlik <mstuchli> - 2.6.6-39
- Remove BOM insertion code from SysLogHandler that causes messages to be
treated as EMERG level
Resolves: rhbz#845802

Closing this out.
