I am using ping to confirm that ICMP/TCP packets are getting delayed. I know both UDP/TCP fall under ip, so UDP packets should also be getting delayed but just to confirm, do you guys know of any utility that I can use to check if UDP packets are also getting delayed. ipfw shows pipe 1 and queue 1 as pipe 1 ip from any to any queue 1 ip from any to any I am running linux on machine-1 and machine-3. TIA -Sushant ps: please cc the reply to me also as I am not subscribed to the list.
