==Filtering dhcp log with syslog-ng==
Configure dhcpd to log to local7, then edit syslog-ng.conf:
# Add destination and filter.
destination df_dhcpd { file("/var/log/dhcpd.log"); };
filter f_dhcpd { match("dhcpd"); };
# Modify /var/log/messages to exclude dhcpd logs
filter f_messages {
level(info,notice,warn)
and not facility(auth,authpriv,cron,daemon,mail,news)
and not match("dhcpd");
# Finally define dhcpd log
log {
source(s_all);
filter(f_dhcpd);
destination(df_dhcpd);
Yea.. sometimes Linux stuff can be overly complicated.
