Description Michal Karm Babacek 2014-11-27 00:05:14 UTC

Dear folks, 
first of all, there is a missing prefix modules/ that's preventing Apache HTTP Server from boot with mod_snmp config loaded:

Proposed fix:
> --- /tmp/jboss-ews-2.1/etc/httpd/conf.d/mod_snmp.conf.sample    2014-07-17 09:00:54.000000000 -0400

Once fixed, the server starts:

With this configuration C:/Program Files/jboss-ews-2.1/etc/httpd/conf.d/snmpd/snmpd.conf

CovalentSNMP does not boot properly, producing the following log.
1) It runs with the default: '161.0.0' instead of '1618.4.53'
2) There are weird notes with superfluous '\n' symbol.

On the other hand, if one tries to connect to port 161 on any interface (thanks to 0.0.0.0) with snmpwalk, module works just fine and it offers the proper tree to traverse.

IMHO, the snmpd.conf isn't being loaded at all.
I tried  to use even a space-free path like:
> SNMPConf "C:/tmp/snmpd.conf"
or
> SNMPConf "C:/tmp"
...without any luck.

WDYT? :-)

Comment 1 Rostislav Svoboda 2014-12-04 19:32:28 UTC

Apache HTTP Server on Windows doesn't start.

Comment 4 Jean-frederic Clere 2015-01-15 12:10:37 UTC

According to my notes the snmpd.conf was read when it was in conf (where httpd.conf is).
In it possible to check that works?

If not it is 2 BZ one trivial to fix and one more difficult.

Comment 5 Michal Karm Babacek 2015-01-27 00:26:09 UTC

Placing it in conf/ helped:
> [notice] SNMP: CovalentSNMP/2.3.0 started (address '1618' - pid '2860')
It appears that the directive in mod_snmpd.conf is either silently ignored or it expects a different format (relative path to dir? absolute path to the actual file?)

> # Directory where that contains the configuration file for SNMP agent
> SNMPConf "C:/Program Files/jboss-ews-2.1/etc/httpd/conf.d/snmpd"

Comment 7 Jean-frederic Clere 2015-02-03 16:32:08 UTC

The BZ isn't a blocker basically only a mod_snmp.conf.sample is delivered and that file needs to be fixed and copied to mod_snmp.conf

Comment 8 Jean-frederic Clere 2015-02-05 17:38:47 UTC

Fixed in jb-ep-6.4-xb
http://pkgs.devel.redhat.com/cgit/rpms/mod_snmp?h=jb-ep-6.4-xb

Please rebuild.

Comment 9 Permaine Cheung 2015-02-05 18:07:44 UTC

Lukas, can you please rebuild mod_snmp and jboss-ews-httpd and let me know when new builds are ready, so that I can update that for ER2 if possible? Thanks!

Comment 10 Permaine Cheung 2015-02-06 15:53:55 UTC

Thanks Lukas for the rebuild. EAP 6.4.0 ER2 natives had been updated to include this fix.

Comment 11 Michal Karm Babacek 2015-02-16 23:43:14 UTC

Both major points of this bugzilla failed QA in EAP 6.4.0.ER2:

- snmpd.conf is still located in a directory the daemon won't read, see BZ 1188769

- log still contains weird error-info\n messages http://fpaste.org/186269/41255631/

Comment 13 Jean-frederic Clere 2015-02-17 09:00:44 UTC

The log message should go in another BZ which has to be handled as a known issue.
