Regarding signatures

Hi all,
sorry a small correction in previous mail..

The signature that is to be matched is the following:
signature gtalk_test {
event "gtalk test received"
payload /\x17\x03\x01/
}

I tried the following signature also

signature gtalk_one {
event "gtalk one received"
payload /.{0,0}\x17/
payload /.{1,1}\x03/
payload /.{2,2}\x01/
}
