IPTables Debugging
So, instead of spending the day trying to get my Fiat working again, I decided to geek out and get UML working again. My goal for the night was to install WebGUI on a UML host...but my goal for the night soon switched to getting networking going on a UML. Jeez. One of the little UNIX tricks I found useful was:
# watch iptables -nvL
Very sweet. Gives you a real time represenation of where packets are going and what chains are seeing them. It's great for a home user. Probably not so great for server usage if the host is live. But you should have that figured out to begin with!
So, I have UML running. I'll see if I can accomplish my other goal. I doubt it. It looks pretty fucking hard. But when I'm done I"ll have a UML image of this install that I can take anywhere. Even work. :)
