DNS problems with Snow Leopard 10.6

September 8th, 2009 Jacken 7 comments

I’ve had some bizarre problems with my DNS today. I checked /etc/resolv.conf but everything looked ok. Checked the settings dialog for my network and at first glance, that one seemed ok as well.

But normally there should be a dimmed version of the DHCP assigned values there.

Just select the empty one and press the minus sign. Sneaky little bug there!

Dimmed DNS values

Save your settings and you should be good to go.

Speedup of the Swedish 3G provider tre

May 8th, 2008 Jacken No comments

After getting a 3G connection on my new toy, I noticed that connecting to a site when browsing the web could take a long time, but as soon as it gets to the page it’s fast. Typical behavior of a slow DNS server. So after changing my /etc/resolv.conf file to use the OpenDNS servers instead, the increase in speed is incredible!

The eee PC use resolvconfig, so to make the changes permanent you need to go to the directory

sudo pico /etc/resolvconf/resolv.conf.d/base
Add these two lines:
nameserver 208.67.222.222
nameserver 208.67.220.220
to the file and save.

My guess is that Tre has a lot of customers that gets annoyed of the slow speed, and all the provider needs to do is to upgrade their dns servers. Or maybe tip their customer of a better alternative. Go figure…
