Re: [syslog-ng] Re: file issues

      So they have to match all of the filters?

I want all of the messages from 4 or 5 devices to go to one log file.
I created a filter for each using the netmask filter. I then used
listed each of those filter commands in the log statement...

It seems that if I add multiple netmask() statements to a single
filter is doesn't work. If I had multiple filter() statements (with a
single device each) to a log statement it doesn't work...

The following is what my final config was before I decided to blow it
away and attack the issue at a much smaller scale (two log files, one
filter, etc. - which is why I now believe the above):

options {
       chain_hostnames (no);
       use_dns (no);
       use_fqdn (no);
       create_dirs (yes);
       keep_hostname (yes);
       owner(syslog);
       group(syslog);
       perm(0660);
       dir_owner(syslog);
       dir_group(syslog);
       dir_perm(0660);
       time_reap(300);
};

source s_snmp { unix-dgram("/dev/snmp"); internal(); };

It is syntactically correct. However, nobody can answer your question
properly (you are using the filter named f_fire which wasn't in your
previous posts, so I have to assume that you have modified your
configuration).
Without knowing your current configuration I can only answer like this:
if a message comes from your any of the sources and matches all of the
filters then it will be logged through the destinations.
