Hi,

Please check your script and strictly follow the template notes. Remember to edit the IP and Port of your host.

Here's a simple test with your command via CLI, from a BIG-IP to a host and it worked:

Terminal 1

echo -n 'Pedro' | nc w.x.y.z 80 | grep "00000000" 2>&1 > /dev/null

Terminal 2

[root@bigip:Active:In Sync] config  tcpdump -ni 0.0 -Xs0 host w.x.y.z and port 80
    00:15:46.389185 IP a.b.c.d.32239 > w.x.y.z.http: Flags [S], seq 4156473052, win 29200, options [mss 1460,sackOK,TS val 2793760084 ecr 0,nop,wscale 7], length 0 out slot1/tmm2 lis=
