Re: DNS problems - slow to resolve
Ok, I wasn't getting the IPs in my resolv.conf because I had dhclient.conf modified to supersede to the local DNS. Here's what I did to determine the DNS that my ISP was assigning me. I changed the dhclient.conf back to empty and restarted the network. This then put the IPs of the two DNS servers assigned into my resolv.conf. I then took these two IPs and added them to my forwarders section in my named.conf. Rebooted and name lookup is much faster now. It only took my wife grumping about having to hit refresh 20+ times to bring up a web page in order for me to fix this since we've moved and changed ISPs. Thanks for the ideas everyone.

Re: DNS problems - slow to resolve
The problem with resolv.conf is that it just puts insightbb.com in there. Doing a whois on insightbb.com gives a few DNS servers but none of them are any speedier lookups then the others. If I put the IP that insightbb.com resolves to it's still slow.

I don't see it when man'ing ifconfig. /etc/resolv.conf lists which nameservers your system is using.

DNS problems - slow to resolve
I'm running BIND 9 for my own DNS and I'm connecting to the Internet through cable modem. In my named.conf I have a forwarders section where I put the IPs for my ISPs DNS. Since my connection to the ISP is DHCP how can I determine the DNS IPs that have been assigned? I don't see it when man'ing ifconfig. Are there tools/commands I can use to determine the resolution time that my lookups are taking? A lot of my web browser requests are timing out (name lookups) and I have to keep hitting refresh until it finally resolves. -- Doc [EMAIL PROTECTED] 317.536.1858 "The only thing necessary for evil to triumph is for good men to do nothing." - Edmund Burke ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
