to mitigate the effects of DDOS attacks (eg. the ones on port 80 and

suggested to turn ON syncookie tcp/ip flag.

syncookie is broken on OS/2's implementation, do not turn it on.

You could try asking Microsoft to release the source code.

Hi Peter,

i recall that the OS/2 stack ip is a porting from AIX.

If it's from Microsoft maybe it was already open source,
like a a number of parts of Windows are today.
