Comment 1 Fabian Deutsch 2013-11-28 14:39:28 UTC

Description of problem:
Rsyslog doesn't work when using server's hostname as server address.

Version-Release number of selected component (if applicable):
ovirt-node-iso-3.0.0-3.999.999.20130716190656git4e57356.2850.fc18.iso
ovirt-node-3.0.0-3.999.20130716190656git4e57356.fc18.noarch

How reproducible:
100%

Steps to Reproduce:
1. Clear install ovirt-node.
2. Configure network and change the dns server into 10.66.11.225 to resolve the hostname we set next.
3. Ping the server with its hostname.
4. Using hostname as rsyslog server address.
   Rsyslog is an enhanced multi-threaded syslogd
   Server Address:           example
   Server Port:              514
5. Check in remote rsyslog server.
   # nc -l -u 514
   In local host, run # echo "test" > /dev/kmsg

Actual results:
After step3, the server is reachable.
After step5, Rsyslog doesn't work.

Expected results:
After step5, Rsyslog works well.

Additional info:
1.No such issue when set Netconsole server address as the same hostname as we set in Rsyslog server.
2.When set rsyslog server with ip address(10.66.106.88), it can receive some messages from rhevh6.5, but also can not recevice the message using # echo "test" > /dev/kmsg command.

Comment 2 Sandro Bonazzola 2014-03-04 09:21:50 UTC

This is an automated message.
Re-targeting all non-blocker bugs still open on 3.4.0 to 3.4.1.

Comment 3 Sandro Bonazzola 2014-05-08 13:56:11 UTC

This is an automated message.

oVirt 3.4.1 has been released.
This issue has been retargeted to 3.5.0 since it has not been marked as high priority or severity issue, please retarget if needed.

Comment 4 Itamar Heim 2014-08-10 20:46:41 UTC

how is this an interesting use case in real life of deploying the node as the syslog server?

Comment 5 Ryan Barry 2014-08-11 16:06:55 UTC

IIUC, this is about using a hostname instead of an IP address in rsyslog.conf rather than using Node as a syslog server

This isn't reproducable on current EL6 images, but is on EL7, as rsyslog.conf is missing a directive to load the module for journald

Comment 6 Doron Fediuck 2014-09-04 10:32:50 UTC

Itamar, see comment 5.

Comment 9 Red Hat Bugzilla Rules Engine 2015-10-18 08:34:47 UTC

Bug tickets that are moved to testing must have target release set to make sure tester knows what to test. Please set the correct target release before moving to ON_QA.

Comment 10 wanghui 2016-02-03 06:21:59 UTC

Test version:
rhev-hypervisor7-7.2-20160126.0
ovirt-node-3.6.1-5.0.el7ev.noarch

Test steps:
1. Clean install rhev-hypervisor7-7.2-20160126.0.
2. Configure network and change the dns serverto resolve the hostname we set next.
3. Ping the server with its hostname.
4. Using hostname as rsyslog server address.
   Rsyslog is an enhanced multi-threaded syslogd
   Server Address:           example
   Server Port:              514
5. Check in remote rsyslog server.
   # nc -l -u 514
   In local host, run # echo "test" > /dev/kmsg

Test result:
1. After step5, Rsyslog works well.

So this issue is fixed in ovirt-node-3.6.1-5.0.el7ev.noarch. Change the status to verified.
