DNS caching can speed up web browsing a bit

You can run a DNS cache on your computer. This will speed up the process of looking up domain names when browsing. The difference is about 30-60 ms for me. Multiply that difference by the number of websites you visit a day for an approximate estimate of the speed improvement. Of course, all this would be worth it if it weren’t for the fact that setting this up is way too easy.

    I have been using DNSMasq for a good long time now. Ees ver' nayze.

    I have a border box running Slackware 10.2, and serving DNS to my whole network via DNSMasq.

    Just for kicks and giggles, I had my Ubuntu box dig google.com, and I got a 15ms response. A re-dig got a response of 1ms.

      The files that they are asking us to edit in the instructions are read only.

      Any idea how to edit read-only files in ubuntu?

        try "sudo" before you invoke your editor...

        e.g.: home-milo$ sudo nano myexamplelocked.file

        so the action will SUDO (Switch User Do) then Nano (the text editor) and open myexamplelocked.file (the file you wish to edit)

        It should ask for your password. you might also check the man page for sudo for more info.

        I'm not all that expirienced in linux/unix, so if someone else want's to confirm this, that'd be great.
