OpenSesamMe

OpenSesamMe is there a tool outthere that work as follows: 1. I'll send a sequence of small ip packets (udp|tcp) to certain ports in a certain order to a server destination. e.g. udp 213,tcp 112,udp 443,udp 4500,tcp 1200 2. The servers has got a daemon that sniffs all incoming packets, filtered too, on certain interface and waits for udp 213. If such a packet arrives, the daemon checks whether the other packets arrives in a certain time in that order or not. 3. If daemon check succeeded, a whole hole will be poked into the firewall for this incoming ip to allow access to e.g. ssh. or any other suggestions for that. And YES, somebody might name this security through obscurity. Thx in advance Michael
