Notes from yesterday.

When setting up one's existing laptop to masquerade a wired connection, it's not enough to stare at /proc/sys/net/ipv4/ip_forward and go "it's 1, why isn't it forwarding packets"? You also have to actually put in the masquerading rule. (Luckily I still have http://dvpn.sourceforge.net/old/firewall-rules.txt after all these years so I don't have to remember "iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE". Yeah, I should take an hour some weekend to reimplement and upload that project, it was fun to have around. I doubt WebOffice would object more than 7 years after they went out of business.)

The firmware to make an iwl6050 wireless card work lives at http://intellinuxwireless.org/?n=Downloads but I had to back down to version 4 because the ubuntu 10.04 kernel didn't understand version 5. It goes in /lib/firmware. The reason it didn't work after _that_ was that my home router filters mac addresses (too slow around here otherwise) and there's a chicken and egg problem adding the mac to it from a machine that's not already in it, but Causal can export a wireless connection and that worked fine.

To turn a vanilla xubuntu install ito something vaguely usable as a development environment, you need to "aptitude install" 8 gazillion things, starting with: libc6-dev manpages-dev mercurial git cvs pdftk g++ gcj libncurses5-dev xmlto diffstat patch libsdl1.2-dev git-core htop

The 64-bit version of skype insisted on installing the 32-bit compatability libraries. I don't know why.

Ze laptop! It is working!
