Hmmm... This could be due to packet loss on your wireless network. DNS, being a UDP protocol in the main, can't distinguish between "response lost in transit" and "no response made by server", so it has to sit and wait for the timeout before trying again. You should be able to tcpdump(1) the port 53 traffic from your caching DNS (or the DNS traffic out of your LAN, if you don't run your own DNS), and cross reference that with the traffic generated by one of your client machines, in order to get clues about exactly where things are going wrong. > Of course, 'batcave.org' is not a registered domain name. Oh yes it is... Just not your registered domain name. =20 Cheers, Matthew --=20 Dr Matthew J Seaman MA, D.Phil. 26 The Paddocks Savill Way PGP: http://www.infracaninophile.co.uk/pgpkey Marlow Tel: +44 1628 476614 Bucks., SL7 1TH UK --y0ulUmNC+osPPQO6 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFAf+VfdtESqEQa7a0RAqGxAKCMCHP9Bx1DA8AGFvn14Oh5JQRcYgCggB3C Rq5ppD7R72b6Yb7Q9NM4vJw= =SsPP -----END PGP SIGNATURE----- --y0ulUmNC+osPPQO6--
