Website Changes.

Today has been a busy day for the poor server must be tired, I’ve made a whole load of changes today including wordpress upgrades and url moves – I’ve removed the word “blog” from everywhere as it was kinda redundant :D

Some content still needs to be ported from my custom php to wordpress, but it should all be finished soon. I’ve got the wonderful redirection plug-in taking care of everything, if you experience any problems please let me know !

Security updates only for Fedora 7 / RHEL & Centos 5

I found this on the other day….

It is now possible to limit yum to install security updates only. To do so, simply install the yum-security plugin and run the following command:

yum update –security

Hopefully this will allow fedora users to have the option of running a “stable” install :)

USB Networking with Fedora 7 & n800

There are times where you cannot use WiFi, for example my workplace’s WLAN uses LEAP, which maemo doesn’t support. I found that setting up USB networking on my n800 was a bit of a pain since there isn’t a single document… if you check my feed you’ll see I bookmarked all I could find with a usbnet tag.

These are the steps I ran through to enable usb networking between my nokia n800 and my fedora 7 laptop.

First we’ll start with the basic setup… I’ll assume you’ve read a getting started article similar to mine and already have root & xterm. By default n800 has a usb interface configured, you just need to enable it, so on your n800 type:

sudo gainroot
insmod /mnt/initfs/lib/modules/2.6.18-omap1/g_ether.ko
ifup usb0

The default settings add an interface with a static ip of with a default gateway of

Now lets set up something similar on Fedora, you need to create a file in /etc/sysconfig/network-scripts called ifcfg-usb0 with the following…


Now plug the usb cable into both devices, and on your fedora box (as root) type

ifup usb0

You now have connectivity, of course if you have a default fedora install pinging will fail because of the firewall, it is probably best to temporarily disable the firewall (/etc/init.d/iptables stop) to see if it works, if so move onto configuring your firewall correctly (/etc/init.d/iptables start starts it again) :) You may also get usb conflicts, you can try

rmmod uhci_hcd

but it will disable any USB devices, you have been warned.

With this basic connectivity setup you’ll have two issues; you only have connectivity between fedora & n800 nothing else works, and opening any application on n800 causes it to try and connect to your wifi, so lets look at those….

I’m going to assume you used system-config-securitylevel to configure your firewall, its worth noting that any changes you make now will be overwritten by any future use of system-config-securitylevel so it’s probably best to take a backup of /etc/sysconfig/ipatbles now and later when you’re finished.

So as root type:

iptables -I RH-Firewall-1-INPUT 2 -i usb -j ACCEPT
iptables -I FORWARD 1 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -I FORWARD 1 -s -j ACCEPT
iptables --table nat --append POSTROUTING --out-interface eth0 -s -j MASQUERADE
/etc/init.d/iptables save

This will allow all connectivity in from the usb interface allowing the n800 to send packets into the fedora box whilst the firewall is running, it will also NAT any traffic from the usb network hiding the n800 behind fedora so that you get onward connectivity. To get the NAT to work you need to enable ip forwarding, this allows fedora to pass pakets between interfaces, to do that type

echo 1 > /proc/sys/net/ipv4/ip_forward

and to get it to survive a reboot update /etc/sysctl.conf with

net.ipv4.ip_forward = 1

The final part is to enable name resolution (DNS), on n800, I updated /etc/resolv.conf with the opendns servers…


All things being equal you should now be able to ping from your n800 :cool:

To get applications to connect, I found on the latest version of ITOS that the DUMMY IAP didn’t work, so I stumbled across this solution.

Create an “ad hoc” wifi connection with static IPs… anything it doesn’t matter, and when that’s connected in xterm (as root) type ifconfig wlan0 down , you should now be able to connect to the web with your browser / skype etc over your usb network… sweet!

Nokia n800 icon

After seeing this post on planet maemo, I wanted to replace my “applications” button with an n800 icon, but I couldn’t find one anywhere… I found a couple of icons in /usr/share/icons/hicolor/scalable/hildon that where close to what I wanted (there’s a bluetooth icon, and input one) but they weren’t quite right, so this is what I managed to mash up. :cool:

Firefox Extension – Flashblock

I’m not a great fan of flash, it seems to eat up bandwith, processor and memory very quickly.. not to mention the hassle of trying it working on a linux x86_64 machine ! I recently came across this great plug-in..

Flashblock :: Firefox Add-ons
Never be annoyed by a Flash animation again! Blocks Flash so it won’t get in your way, but if you want to see it, just click on…

The white-list functionality is nice… i.e block all except “blah”.. the option to run it in a black-list mode would be good for those who are only offended by flash on certain sites.

My Maemo Bugs Activities.

Apologies to anyone who works on the bugs.maemo team, I was bored this AM and decided to ask for some features I want, as I felt guilty about using up someones time (who could be coding fixes for real problems), I also decided to check if some bugs reported by other people where also bugs on my n800…. ahh, back to work :D
