[syslog-ng] Filter Not Working (too many or's?)

[james.r.hendrick]

Not exactly what you asked but I have used netmask to simplify some filters. Although it probably won't be able to solve your problem.

Hi,
 
First of all, the content of the host() is a regular expression, so adding .* to the beginning and/or to the end of the expression adds nothing, just pain/slowness.
 
Second, it would help a lot if we can see the actual error message. I found no obvious mistake, but because this is not the original line, maybe something lost
 in the translation.

Here is an example of what I am trying to do, these hostnames are not real; the real ones have no common pattern.
 
filter f_xyz         { host("*.abca.*") or host(".*abcb.*") or host(".*abcc.*") or host(".*abcd.*") or host(".*abce.*") or host(".*abcf.*") or host(".*abcg.*") or host(".*abch.*"); };
 
The filter above is for any host containing a hostname with what is contained within the .* and *.; i.e. hostabca01 will be matched by host("*.abca.*")

 
When I have this filter in my config, syslog fails to restart.
 
Eyes hurt, obvious mistake?
