# Tune me, put me in /etc/systrace/usr_local_bin_ngircd and start ngIRCd
|
||
|
|
# (with root privileges) as:
|
||
|
|
#
|
||
|
|
# systrace -a /usr/local/bin/ngircd
|
||
|
|
#
|
||
|
|
# I didn't tried this on NetBSD, but it should work as is.
|
||
|
|
#
|
||
|
|
# On systems with pf, it can be supplemented by strict firewall rules:
|
||
|
|
# for a ngircd running as '$ircuser', binding on '$ircport' and accepting
|
||
|
|
# 30 connections:
|
||
|
|
#
|
||
|
|
# block out log quick proto tcp from any port $ircport to any \
|
||
|
|
# user != $ircuser
|
||
|
|
# pass in inet proto tcp from any to any port $ircport user $ircuser \
|
||
|
|
# keep state (max 30) flags S/SA
|
