[Hampshire] Humble bundle: games!

2012-03-20 Thread Anton Piatek
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.

See http://www.humblebundle.com/ for more

How or why does this problem occur? I can't think of an explanation.

 Hi,

 Sometimes, a network will have black holes in the sense that say,
 packet sizes up to 0-1400 get through, 1400-1404 fail, and 1405-1500
 get through.
 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?

 Kind Regards

 James

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.
