tinc - Feb 2001 - how to test

Hi,

I got a small VPN (2 hosts so far) running tinc. The connection is established,
according to netstat, so I guess the configfiles are ok. When starting the
deamon, nothing appears in syslog, not even when running with -dddd. So the VPN
should work, but it doesn't. Pinging doesn't work, let alone TCP
services as
ftp or http.

Are there ways to test/diagnose the VPN? 

TIA
Bart

You should wield tcpdump on the network device over which the packets
leave the computer (eth0) and carefully examine its output.

If you left the port number unchanged, look for UDP packets on port
655.  Then check if they reach the other end.

If they don't you might have a firewall that filters them out, or if
they do reach the other end, then maybe your ethertap device is not
configured properly (tap0's MAC address should be fe:fd:00:00:00:00
from 1.0pre3 on).
