[syslog-ng] How does regex work with HOST definitions?

[Jason Haar]

Hi there

I have a subset of syslog-ng hosts that use a specific DNS formatted
naming convention that I wish to ensure all their data is caught by a
particular syslog-ng filter.

I have

filter f_process_Test { host("^...\-..\-ids\-[0-9]+\...\.our\.net$") and
not host("abc-xy-ids-02\.our\.net"); };

i.e. I want abc-12-ids-01.aa.our.net and xyz-12-ids-01.aa.our.net to be
caught by this filter, but abc-xy-ids-02\.our\.net not to be.

I could explicitly name them all I suppose - but there are 12+ of them
and they are growing in number. A regex would be much more efficient.

Anyway, it doesn't work. That filter never triggers. I know the
hostnames are correct as I have a general catch-all rule that logs to
filenames containing the hostname - and those hostnames show up in there.

Can anyone explain what I've got wrong? REGEX works fine in my "match"
calls...

This is syslog-ng-1.6.7-2 under CentOS4.1

Thanks!
