I'm looking at a few options to deal with people who abuse time servers
(specificly the pool.ntp.org ones). One idea I have is to send the wrong
time to abusive clients [1] so that the clients owner actually has an
incentive to fix their behavour [2].
I've made a slight modification to MSNTP (sntp server) to always return
exactly the same time (In June 1998) to the client. I would appreciate if
people could point their clients at it (especially Windows based
shareware/freeware programs) and let me know what the result is.
The IP of the server is 202.49.59.7 [3] . I would be interested to know
what it does both as the sole server configured or when other servers are
configured as well.
[1] - Probably after sending them a "kiis of death" packet.
[2] - Many clients ignore kod and some will retry forever when you just
block them.
[3] - Actually the servers runs on port 11123 but I've setup iptables
rules to redirect requests to 202.49.59.7 on port 123 to to port 11123.
