DNS Flood Detector was developed to detect abusive usage levels on high traffic
|
||||
nameservers and to enable quick response in halting the use of one's nameserver
|
||||
to facilitate spam.
|
||||
|
||||
DNS Flood Detector uses libpcap (in non-promiscuous mode) to monitor incoming
|
||||
dns queries to a nameserver. The tool may be run in one of two modes, either
|
||||
daemon mode or "bindsnap" mode. In daemon mode, the tool will alarm via syslog.
|
||||
In bindsnap mode, the user is able to get near-real-time stats on usage to aid
|
||||
in more detailed troubleshooting.
|
||||
|
||||
A /etc/rc.d/rc.dnsflood daemon control script is aditionally included.

# 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 ':'.
