Quick and dirty VoIP test using ping

October 15, 2007 1 comment

ping -i 0.02 -s 270 -c 500 <ip address>

You need superuser privileges to perform a ping with a .02 second interval. The -s 270 is the size of a ulaw SIP packet. The -c denotes 500 packets. The resulting ping flood will simulate a SIP packet flow. You can quickly see any lost packets and the jitter. QOS settings can cause this type of traffic to not act exactly like SIP traffic.

Kill list of processes from command line

This is a very well written description of a command to kill all processes that match a name in the process list.

kill `ps aux | grep Mozilla | grep -v grep | awk '{print $2}'`
