referral problem
Authored by: DavidHolcomb on Nov 20, '02 05:26:18PM

I have been having this problem since I installed Jaguar. I think that it is a referral interpretation problem - It only occurs for high traffic sites (eg yahoo, orbitz, etc.). I can use http://www.dnsstuff.com/ to get a site referral and then directly input the referred site which functions properly. For example, search.yahoo.com yields

How I am searching:
Searching for A record for search.yahoo.com at f.root-servers.net: Got referral to B.GTLD-SERVERS.NET. [took 251 ms]
Searching for A record for search.yahoo.com at B.GTLD-SERVERS.NET.: Got referral to NS1.yahoo.com. [took 125 ms]
Searching for A record for search.yahoo.com at NS1.yahoo.com.: Reports search.yahoo.com. [took 125 ms]
Answer:
Domain Type Class TTL Answer
search.yahoo.com. CNAME IN 10800 newsearch.yahoo.akadns.net.

Cixco PIX firewall DNS bug
Authored by: DavidHolcomb on Dec 05, '02 04:00:25PM

I have finally tracked down the DNS problem I have been having - evidenced by erratic behavior on larger websites (yahoo for example). The Cisco PIX firewall I am behind drops DNS responses that are bigger than 512 octets. Cisco has confirmed that this is a bug (Bug ID CSCds58726) - expected to be resolved in the next version of the PIX OS in Jan/Feb 03.
