How do I set up PingPlotter to use TCP packets?
The target I'm tracing to doesn't respond in PingPlotter, but it works just fine in my browser. Is there any way to access it?
By default, PingPlotter uses ICMP echo requests - which are sometimes blocked by target servers. If your web browser works to a target site, but PingPlotter does not, it might be time to try the TCP packet type.
Note that ping and traceroute with TCP is not possible with many tools, and because of this it is not always well supported by routers. An example of this is the Actiontec DSL modem provided by Qwest - it doesn't work well at all with TCP packets in PingPlotter. If you have similar problems, you might need to pick a target site that accepts ICMP echo request and use ICMP instead of TCP.
To set up TCP ping packets with PingPlotter, you may need to install a 'helper' driver called Npcap. Windows XP Service Pack 2 and all newer versions of Windows require the use of this driver. See our website for more details on this.
To configure PingPlotter for TCP:
- Go to the Edit -> Options menu.
- Select 'Engine' from the list on the left.
- In 'Packet Type', select 'TCP Packets (ie: HTTP, etc)'.
- In 'Timeout speed', enter: 3000
- In 'Packet Size', enter: 40
- Ensure that 'HTTP' is selected as the TCP Port (if you want
- Hit the 'OK' button.
- If you're running a software firewall, make sure your firewall allows packets to be sent from PingPlotter on port 80. See your firewall instructions for more details on this.
