I am using syslog-ng 3.1.2 and I am having a problem that I can not figure out. Our network gear sends messages to syslog-ng, and then it filters them based on device type, and name. There is one firewall, that is matching both the firewalls filter and the switches filter, and is subsequently writing to both locations. in the example below, host 1.2.3.5 is logging to both the switches log dir and the firewalls log dir even though it is only referenced in the firewalls filter. Other then the obvious possibilities, (Yes, I have confirmed that the ip address is only referenced in one filter) does anyone have any ideas on what I should look at? Thanks, Burton our filters look like this (each host filter has several addresses in it): filter f_firewalls { host(1.2.3.4) or host(1.2.3.5); }; filter f_switches {host(9.8.7.6) or host(9.8.7.5); }; destination d_firewalls {file( "/path/to/logs/fw/$YEAR/MONTH/$HOST-$YEAR$MONTH$DAY" create_dirs(yes) owner(log_owner) group(log_group) dir_perm(0775) perm(0664) ); }; destination d_switches {file( "/path/to/logs/sw/$YEAR/MONTH/$HOST-$YEAR$MONTH$DAY" create_dirs(yes) owner(log_owner) group(log_group) dir_perm(0775) perm(0664) ); }; log { source(s_network); filter(f_firewalls); destination(d_firewalls); }; log { source(s_network); filter(f_switches); destination(d_switches); }; Version info: syslog-ng 3.1.2 Installer-Version: 3.1.2 Revision: ssh+git://bazsi@git.balabit//var/scm/git/syslog-ng/syslog-ng-ose--mainline--3.1#master#8bf13c304b6ab5fc1a372b49d55c78370efe14ca Compile-Date: Aug 3 2010 11:16:08 Enable-Threads: on Enable-Debug: off Enable-GProf: off Enable-Memtrace: off Enable-Sun-STREAMS: off Enable-Sun-Door: off Enable-IPv6: on Enable-Spoof-Source: on Enable-TCP-Wrapper: off Enable-SSL: on Enable-SQL: on Enable-Linux-Caps: on Enable-Pcre: on
