Spamhaus DROP list
The Spamhaus DROP list (Don’t Route or Peer) is still awaiting it’s BGP feed for network providers. So in the meantime, I’ve knocked up a little PHP script that downloads the DROP list from Spamhaus and spits out either a list of IPtables rules or a Cisco access control list.

Pet Hate: MTR
MTR, also known as Matt’s Trace Route, is an enahanced traceroute utility which after making the initial run continues to rerun the traceroute and calculate hop-specific packet loss and latencies.
Unfortunately, virtually everytime someone calls me and mentions “packet loss” and “MTR” in the same breath, it’s because they do not understand the output.
