Fix a buffer overflow that could be used to perform a DoS attack
and possible code execution.

ftpsesame helps the FTP protocol get through your pf firewall. It does
this by passively analysing FTP control connections and adding rules
into a pf anchor when an FTP data connection is about to commence.
You might want to try ftpsesame instead of ftp-proxy(8) from the OpenBSD
base system for the following reasons:
- it runs on "transparent" (no IP address) bridges
- you need packetfilter performance on all data connections
- you have to handle lots of simultaneous sessions
- you do not want to redirect any traffic to the firewall itself: for IP
accounting or other reasons
client under some bizarre conditions would not start, no error messages
or anything.
nasty diff from mjc@, poor marco@ was suffering due to this issue.
Kismet is an 802.11 layer2 wireless network detector, sniffer, and
intrusion detection system. Kismet will work with any wireless card
which supports raw monitoring (rfmon) mode, and can sniff 802.11b,
802.11a, and 802.11g traffic.
Kismet identifies networks by passively collecting packets and detecting
standard named networks, detecting (and given time, decloaking) hidden
networks, and infering the presence of nonbeaconing networks via data
traffic.

other people.
Nagios is a host and service monitor designed to inform you of network
problems before your clients, end-users or managers do. The monitoring
daemon runs intermittent checks on hosts and services you specify using
external "plugins" which return status information to Nagios. When problems
are encountered, the daemon can send notifications out to administrative
contacts in a variety of different ways (email, instant message, SMS, etc.).
Current status information, historical logs, and reports can all be accessed
via a web browser.
NOTE: Nagios might not work on 64bit archs.
