Hardware capture platforms
by John A. Kilpatrick 08 Aug '08

08 Aug '08

We've deployed a bunch taps in our network and now we need a platform on which to capture the data. Our bandwidth is currently pretty low but I've got 8 links to tap, which means I need 16 ports. Has anyone done any research on doing accurate packet capture with commodity hardware? -- John A.

IPv6 bogons/unallocated space list?
by Deepak Jain 07 Aug '08

07 Aug '08

Is there such a beast yet? I didn't see anything on the CYMRU page (so its either completely obvious, or not there). Given the shrinking use of IPv4 bogon lists and the increasing need of a well-updated IPv6 one, I figured I'd ask. thanks, Deepak

gTLD root nameserver anomaly

Something weird seems afoot in the root nameservers. I am noticing that the root nameservers are handing out extra info with TTLs much longer than those delineated in the respective zone file on the authoritative nameserver for that zone. Case in point: I asked my local DNS server for ns2.gamespy.com and it went directly to a gtld server (f.gtld-servers.net.) 08:25:27.541627 IP 172.19.2.15.45505 > 192.35.51.30.domain: 42289% [1au] A? ns2.gamespy.com.
