How-To: Setup IPv6 Connectivity using DD-WRT

I was bored. Plus it was planned long before anyway. [Why just now? It’s either i have other things to do, or I had to let go of the completely-configured AP to deploy somewhere else.]

So here’s how i set-up an IPv6 connectivity using Tunnelbroker and a Linksys WRT54G running on DD-WRT firmware.

I. Setup an account in Hurricane Electric’s Tunnelbroker.

  1. Signup for an account in TunnelBroker. Be ready to provide information, such as your valid email address. The password will be delivered to your email.
  2. Once you have logged in, click “Create regular Tunnel” under User Functions in the left-hand side of the screen. NOTE: you can also create BGP tunnel (haven’t tried yet)
  3. In the “Setup IPv6 Regular Tunnel” page, input your static public IPv4 address. Note that this should be reachable via icmp before it can be added.
  4. Select the server closest to you. I chose Hong Kong. Then Submit.
  5. Check the Tunnel Details for your newly created tunnel. You are allowed to create a maximum of 4 tunnels for your account.
  6. Continue reading “How-To: Setup IPv6 Connectivity using DD-WRT”

How-To: Add Static Route in Mac OS X

And because i feel lucky today, (0n a Friday the 13th, that looks kind of odd), here’s another how-to. This is how I added a static route on some Xserves.

Simple solution: route -n add

Permanent solution: Add a startup item (to avoid doing the above command every reboot)

cd /System/Library/StartupItems
mkdir AddRoutes
cd AddRoutes

Create a file called AddRoutes (note: same as the folder name)
vi AddRoutes

How-To: Setup an NTP Server in Mac OS X

It’s been a while… Here is a simple guide in setting up an NTP Server in your Mac OS X. Although it does look trivial, it took me a while to figure it out (and find solutions out there). Steps 1 & 2 are important, as it does the trick.

  1. Disable the synchronizing of the local clock to ntp. Uncheck “Set date & time automatically.”
  2. If you find NTP in the services offered in Server Admin, stop it also.
  3. Open the Terminal. Create or edit /etc/ntp.conf and add the ntp servers from where you will synch.
  4. server minpoll 12 maxpoll 17
    server minpoll 12 maxpoll 17
    server minpoll 12 maxpoll 17
    server minpoll 12 maxpoll 17
    server minpoll 12 maxpoll 17 Continue reading “How-To: Setup an NTP Server in Mac OS X”

The Day the Routers Died

This is an old video/song for network geeks. I’m sure many of you have seen it before (me included). But then I’m fresh from APRICOT 2009 Conference, and this blog is getting stagnant as well. So I decided to post something related.. So here goes…
