The World's Greatest Hacker

What makes a great hacker - the ability to takes someone else's work, find out what modules it has, and then use those modules to create something you want - or an extension of the original work. Here's an example :

Das ist Moeglisch

With a linux guru's help:

use about:config in the browser to get some possibly useful info.

Install nmap on your other PC to find out stuff about your XO.

ps -u olpc
will give you some useful information as well.

We found that su directly gives you root access. They should atleast ship it out with the default password being something you picked at payment time or something.

> yum
can do stuff for you - Yet another Update Manager

> yum check-update

To reboot, you can do
> reboot

During reboot, you can try CTRL-ALT-F11 or CTRL-ALT-F12 to look at the boot sequence. We found all of CTRL-ALT-F1 to F4 give you something useful.

Even though we upgraded the kernel, it was still booting with the old kernel.

I had put a password on the olpc account that I'd forgotten, but as the root account didn't have a password, I could use the SSH client on my PC to get into the XO. Use the router to find out what IP address has been assigned it - my case was 192.168.0.101. Username root, port 22.

They do have a remote desktop client available. nxclient or etwas.

But, what I did, that I hadn't read about was use my cygwin install to do

> ssh -X root@162.198.0.101

and then, I could launch an xterm, and, the best part - CTRL-rightclick gave me the large font - and I could get the xterm to take up the whole screen. Thus, we have gotten past the tiny screen. One small step fur mich. Eine giant leap fur mankind.
