Hey all,

I am trying to get my head how to script this.

I want a packet capture when SNORT alerts that a server is getting a UDP
packet.

I know the rule is alert UDP any any - > serverip any.

Its not exactly a scripted packet capture but it can ressemble what you want.

http://manual.snort.org/node529.html

alert udp any any  -> server_ip any (msg:"blabla to server";
sid:10000001; rev:1;   tag:host,0,packets,src;
flowbits:set,INCOMMING_STUFF)
alert udp server_ip any  -> any any (msg:"blabla from server";
sid:10000002; rev:1;   tag:host,0,packets,src;
flowbits:isset,INCOMMING_STUFF)

-elz
