Ethereal is used to analyse the network traffic.

We captured the network data with the following machines:

192.168.1.101 - Asterisk #1
192.168.1.106 - Asterisk #2
192.168.1.3   - Windows machine 1 (also running both VMware's for both Trixboxes)
192.168.1.189 - Laptop #1 running only X-lite

After capturing we filtered out other data to machines not on the local network (IP-adress other than 192.168.1.x), using this filter:

ip.src >= 192.168.1.1 && ip.src <= 192.168.1.255 && ip.dst >= 192.168.1.1 && ip.dst <= 192.168.1.255

The following screenshot shows network-traffic (in Bytes/s) for the following connections:

  • Black: traffic from and to Trixbox #1
  • Red: traffic from and to Trixbox #2
  • Green: traffic from and to Windows machine #1
  • Blue: traffic from and to Laptop #1
  • Pink: traffic between Windows machine #1 and Laptop #1
