monitoring VPN
 

How will I monitor the traffic of tun0 ?

Hi!

In what capacity are you looking to monitor it?

Do you need individual packet monitoring, or is it more like filtering web traffic you're after?

Also, which distribution and version are you using?

X-T

did you try iptraf?

Yes,I have tried and iptraf does not show any activity on tun0 interface.

I am using CentOS 5. I dont need filtering. I just want to see a iptraf like monitoring, like how much users are connected to tun interface and like iptraf..

Hi,

I've not used IPTraf, and this won't be any use if you're not running X, but have you thought about potentially using Wireshark? It may well provide the facility you require.
