+psad (Intrusion Detection and Log Analysis with iptables)
+
+psad is a collection of three lightweight system daemons (two main
+daemons and one helper daemon) that run on Linux machines and analyze
+iptables log messages to detect port scans and other suspicious traffic.
+A typical deployment is to run psad on the iptables firewall where it has
+the fastest access to log data.
+
+You can set email for alerts by setting ALERTSEMAIL:
+
+ALERTSEMAIL=alerts@example.com ./psad.SlackBuild
+
+You need at least these rules:
+
+iptables -A INPUT -j LOG
+iptables -A FORWARD -j LOG
+
+but more usefull will be something like this:
+
+iptables -A INPUT -i lo -j ACCEPT
+iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
+iptables -A INPUT -p tcp --dport 22 -j ACCEPT
+iptables -A INPUT -p tcp --dport 80 -j ACCEPT
+iptables -A INPUT -j LOG
+iptables -A INPUT -j DROP
+
+please see documentation for more information.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
