DNS caching locally ...
I understand that it is possible to speed up surfing, especially using a wireless Internet connection, by using DNS caching locally. This has to do with enabling the named daemon or something, but I understand that there are some restrictions. Is there a simple recipe explaining how to do this? -- Kiffin Gish Gouda, The Netherlands ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I understand that it is possible to speed up surfing, especially using a wireless Internet connection, by using DNS caching locally. This has to do with enabling the named daemon or something, but I understand that there are some restrictions. Is there a simple recipe explaining how to do this? The FreeBSD handbook has an example. Just skip anything about setting up authoritive name servers. That said, if all you need is caching (ie. you have upstream nameservers you can use), I'd suggest dnrd. It's extremely easy to setup. It's in the ports. http://dnrd.sourceforge.net/ What DNRD is Domain Name Relay Daemon is a caching, forwarding DNS proxy server. Most useful on vpn or dialup firewalls but it is also a nice DNS cache for minor networks and workstations. Features * Caching of DNS requests. * Support for backup DNS servers. * Uses random source port and random query ID's to prevent cache poisoning. * Support for simple routing - specify different forward DNS servers for different domains. * Force authorative or unauthorative answers for specified domains. * Share the /etc/hosts over the network. * Support for openbsd, freebsd and linux. * TCP support * DNS blacklist support -philip ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Basically, edit /etc/rc.conf and add named_enable=YES, run /etc/rc.d/named start (you only have to do this if you don't want to reboot), then edit /etc/resolv.conf and add a nameserver 127.0.0.1 line in front of any nameserver lines you may already have. If you are behind a firewall that blocks DNS requests except to specific servers, you may have to edit /etc/namedb/named.conf and uncomment/edit the forwarders block to tell named to forward requests to those servers. -- Dan Nelson [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
