[Hampshire] Humble bundle: games!
In case you haven't seen it, the latest Humble Bundle is out, and features games for linux and android (and other OSs). It is worth noting that Linux users are the most generous when it comes to choosing how much to pay.

Re: [Hampshire] Black Hole detection
How or why does this problem occur? I can't think of an explanation.

You can find these holes using ping with DF bit set and various sized pings. If you find problems, you then fix them so all sizes get through. Does anyone know of a tool that will automatically scan all packet sizes and report the result?

Does anyone know of a tool that will automatically scan all packet sizes and report the result? I use libipq (on Linux boxes) with Perl (most of the time) or C. Its inline with something like : iptables -A OUTPUT -j QUEUE which passes packets to userspace. Then I write some code to inspect the packets and, if needed, manipulate them. Its actually the onld fashioned way, AFAIK netlink is the way to go nowadays. Either way, its really worth a look. Regards, Zak. ps. James, i'm testing those boards this week, will let you know what choices are available. -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --
