I've got some strange problems with trying to use the syslog-ng host filter. It seems that every logline matches the filter f_comware but none of them match f_netscaler. It makes very little sense to me. Reverse dns is working as the logs that end up in /var/log/remote have the correct hostname being logged from the $HOST template.

I have a second issue that SEC does not die when syslog-ng is restarted. (I have used this setup in the past and have had no problems, but i suppose things may have changed in both syslog-ng and sec since the last time)

This is driving me crazy.. please help ;)

#config

@version: 3.1

# Syslog-ng configuration file, compatible with default Debian syslogd

# First, set some global options.

options { long_hostnames(on); flush_lines(0); use_dns(yes); use_fqdn(yes);

dir_perm(0755); dir_group("adm"); stats_freq(0); log_fifo_size(200000); create_dirs(yes);

bad_hostname("^gconfd$"); chain_hostnames(no); keep_hostname(no);

};

source s_remote { udp();tcp(); };

destination d_remote { file("/var/log/remote/$HOST/$YEAR-$MONTH-$DAY.log" template("$R_DATE $HOST $MSG\n") template_escape(no)); };

destination d_netscaler { program("/usr/local/sbin/sec_netscaler" template("$R_DATE $HOST $MSG\n") template_escape(no)); };

destination d_comware { program("/usr/local/sbin/sec_comware" template("$R_DATE $HOST $MSG\n") template_escape(no)); };

filter f_netscaler { host("lb*ae1.mydomain.com"); };

filter f_comware { host("(as|cs|r)*ae1.mydomain.com"); };

log { source(s_remote); destination(d_remote); };

log { source(s_remote); filter(f_netscaler); destination(d_netscaler); };

log { source(s_remote); filter(f_comware); destination(d_comware); };
