Subject: [syslog4j-support] getHostName vs. getCanonicalHostName to retrieve
	FQDN
Message-ID: <BANLkTinrEg+Scat4c5F5NjXvtT5NxssZ7Q@mail.gmail.com>

Good morning,

I'm having a problem with Graylog2 server finding the correct
hostname, which somebody traced to?SyslogServerEvent.java within
syslog4j.

The problem is that my host names are x.y.z.com, and I'm getting only
"x" as the hostname.

Here's the quote from http://jira.graylog2.org/browse/SERVER-23

"As part of the getHost function in syslog4j it calls getHostName on
the IP as opposed to getCanonicalHostName, which is why you only get
the first part of the FQDN.This can be fixed by modifying line 87 of
productivity/java/syslog4j/server/impl/event/SyslogServerEvent.java
within the syslog4j library itself, replacing getHostName with
getCanonicalHostName."

I'm not sure if this constitutes a 'bug' or and 'improvement' in
syslog4j, or if it is by design, but from what I can tell it would
solve my problem.  If you think it is generally applicable, it seems
like an easy fix.

Also, apologies if this has already been discussed; I didn't see
anything specific.

Thanks,

-nick
