My name is Tony, and I bought an XO Laptop for my son, Miguel. Although he's two, I'm hoping this will be a laptop he can grow older with.

My OLPC Blog

21:55, 4 January 2008 (EST) I have a server at my house (currently a web/mail/file server for various websites I run) that I'm trying to add XS Server capability on. I'm using Ubuntu though, and so I'm working to get the XS Software to work on it.

The server's capabilities are: Intel Pentium D 930, 4 GB of memory, 500 GB of hd space (more will be added as needed should it be necessary.

I'm in the process of getting a WG111 USB Wireless Adaptor to serve as a School node. I'll post details of how it's going at some point.

01:19, 6 January 2008 (EST) Installing Hamachi Section added

10:05, 7 January 2008 (EST) Spend most of Sunday trying to get the Xvid drivers to work with totem (which comes built-in to the xo. Didn't work. I'll continue working on it (since all of my videos are Divx/Xvid format.) *shrugs*

Installing Hamachi

Part of the reason I want to install Hamachi is so my son will be able to view videos on our home server. I have DVD's ripped to the harddrive, and totem is pre-installed on the OLPC. I've got Hamachi VPN on all the computers in the house, and would like to add it.

Downloading Hamachi

You need to get a copy of the code for Hamachi and put it in the /usr/src folder, We'll start by switching to the superuser, then getting the source code 

su
wget http://files.hamachi.cc/linux/hamachi-0.9.9.9-20-lnx.tar.gz
tar -xvzf hamachi-0.9.9.9-20-lnx.tar.gz

This creates a folder hamachi-0.9.9.9-20-lnx which will hold the source code.

Installing make

To continue the install. you have to switch to the directory and type make install. make is not already installed on OLPC, so you need to install it by typing 

yum install make

. It should install all the necessary parts to make.

Installing the Hamachi program

To install the hamachi executables (hamachi, hamachi-init, and tuncfg), you'll need to change to the directory and type make install. Then you need to type tuncfg to start the tunnel configuration (Hamachi uses ssh to tunnel to other members of the VPN.) 

cd hamachi-0.9.9.9-20-lnx.tar.gz
make install
tuncfg

Accessing the existing Hamachi VPN

Set up a shell file (I called mine hama.sh) with the following lines of code: 

tuncfg
hamachi-init -c /etc/hamachi
hamachi -c /etc/hamachi start
hamachi -c /etc/hamachi set-nick olpc
hamachi -c /etc/hamachi login
hamachi -c /etc/hamachi join NETWORKNAME NETWORKPASSWORD
hamachi -c /etc/hamachi go-online NETWORKNAME

In the code above, change olpc to whatever name you want, or leave it. Change NETWORKNAME and NETWORKPASSWORD to the VPN Network Name and Network Password.

Then type ./hama.sh to execute it. This will connect you to the network.

At this point...

If you type ifconfig, you should see something like this:

The important part is you now have ham0 as a network adaptor. At this point, you can access other computers (via ssh, sftp, ping etc.) through their Hamachi IP addresses.

To Do:

Set up Hamachi as a service (i.e., automatically at boot)
Mounting shares using /etc/fstab (so file systems show up at boot)
