I just took a closer look at something odd I'd noticed several days ago.
One of our DNS servers was sending crazy amounts of ARP requests for IPs
in the /24 its main IP is in. What I've found is we're getting hit with
DNS requests that look like they're from "typical internet traffic for

Would address anonymization work? Instead of removing src/dst ip, you
can zero them.

Log sanitation is a whole lot easier than packets. AFAIK, santizing
pcaps is an intractable problem because of various kinds of encodings
that exist within packets.
Examples:
- FTP IPv4 addresses are comma separated
- DNS does label encoding of domain names (especially with pointers)
- Forwarded
Dude,
LTE and WiMax a more siblings, than distinct rivalries. The technologies will
grow together over time, versus, one taking the ascendancy, and the other,
descent. WiMAX is here today, and long term evolution, well, let's see how the

We are having a strange routing issue. If anybody from Shaw cable
could contact me offlist I'd be very thankfull.
The future of WiMAX seems a lot less promising now that FD-LTE is the
clear winner for wide-scale mobile deployment, and TD-LTE, 802.11n and
proprietary technologies will compete for non-paired spectrum and/or
niche markets.
But one can build a network with WiMAX and make money out of it;

A while back I remember reading a comment here that "WiMax is not a
future proof technology" and that several manufacturers have dropped it
or something to that effect. I think it was in the starting a WiMax ISP
thread. This has stuck in my head, and I was curious if there was any
truth to this.

Hello,
Anyone know of a good tool for sanitizing PCAP files? I would like to
keep as much of the payload as possible but remove src and dst ip
information.
