Wimba Live Classroom UDP

It's actually rather interesting piece of software that allows for a virtual classroom. I know, I know, there's netmeeting and everything else. But this is really cool because it all even works on Linux. It's completely Java based (and it doesn't look or behave like it) and takes advantage of the Java multimedia hooks in into the OS. It's really brilliant. The people who designed this I think are Mac heads, so they made it ultra portable.

In any case, it was being shoddy through the R61 NGX. I finally, think, figured out why it the UDP connection was being dropped every so often. It has something to do with the UDP 5998 (that's what they use) service's "Virtual Session Timeout". I increased it from default 40 seconds to 120 seconds, and that seemed to do the trick. Apparently they send out a packet back to the user every 90 seconds, and even setting it to 90 second timeout didn't work.

Num-Lock Keypad Broked

So, is it just me or has everyone lost their ability to use their keypad under X11 with Fedora 7 and Fedora 8?

SSH / Socks5 Proxy

So I've been using an SSH tunnel for proxying my connections. This is particularly useful when on an insecure wireless network. Well, I just found out that Socks 5 supports DNS proxying, but that you have to specifically turn that on.
about:config
Then filter on: network.proxy.socks_remote_dns, set to true. What's the point of keeping your browsing secret if they can see what sites you make a DNS request for.... it's all about plausible deniability.
