 Posted: Mon Jun 20, 2011 11:54 pm Post subject: Syslog-ng Separate IPTables Log [SOLVED] |
 |
|
For quite some time now I have been trying to get syslog-ng to generate/use a separate log file for iptables. It would seem that the sources that I have looked at via Google do not help and I am now lost. Syslog-ng will not generate a log file, but the "iptables:" filter does seem to work and is placed in kern.log. I can only assume that I am missing something, or syslog-ng is faulty somehow.
This is the current state of my syslog-ng.conf file:
| Code: | options {
chain_hostnames(no);
stats_freq(43200);
};
source src {
unix-stream("/dev/log");
internal();
};
source kernsrc {
file("/proc/kmsg");
};
destination firewall { file("/var/log/firewall.log"); };
destination authlog { file("/var/log/auth.log"); };
destination _syslog { file("/var/log/syslog"); };
destination cron { file("/var/log/cron.log"); };
destination daemon { file("/var/log/daemon.log"); };
destination kern { file("/var/log/kern.log"); file("/dev/tty12"); };

Here are the lines I use to log iptables to a separate log file and exclude them from /var/log/messages
| Code: | destination iptables { file("/var/log/iptables"); };
filter f_iptables { facility(kern) and match("IN=" value("MESSAGE")) and match("OUT=" value("MESSAGE")); };
filter f_messages { not facility(auth, authpriv, kern) and not filter(f_iptables); };
log { source(kernsrc); filter(f_iptables); destination(iptables); }; |

This is what I do:
| Code: |
iptables -A OUTPUT -j LOG --log-prefix firewall:
ip6tables -A OUTPUT -j LOG --log-prefix firewall6:
iptables -A INPUT -j LOG --log-prefix firewall:
ip6tables -A INPUT -j LOG --log-prefix firewall6:
$iptables -A INPUT -p tcp --dport ! 135 -j LOG --log-prefix firewall:
$iptables -A INPUT -i ! ppp0 -j LOG --log-prefix firewall:
iptables -A FORWARD -j LOG --log-prefix firewall:
ip6tables -A FORWARD -j LOG --log-prefix firewall6:
|
which puts a prefix in every line, that iptables puts out.
| Code: |
filter f_firewall { match(".*firewall:.*") or match(".*firewall6:.*"); };
|
filters it out[/quote] |
