Yes, from the other ISPs, dig @their.servers and dig @my.own.servers works fine. On SAIX, dig @anybody.server only gives me a timeout. The box uses ipfw in a stateful setup, but even with that comletely out of the way, there's no difference. /etc/resolv.conf is static, but the address in there is correct. -- Willie Viljoen Freelance IT Consultant 214 Paul Kruger Avenue, Universitas Bloemfontein 9321 South Africa +27 51 522 15 60 +27 82 404 03 27 (mobile) will@unfoldings.net
