PingTimeout

[Cédric Lemarchand]

Hello list,

I use tinc with QOS, and since some weeks I got problem with tunnel 
disconnection because the default "Pingtimeout" of 5 sec is reach.
I think it happens because of the QOS shappe the tinc traffic (data 
here) to let some BP for VOIP, but whate is very strange is that the 
ICMP protocol is not include in the shapping, so tinc would never 'see' 
latency on the link, even if there is latency caused by the QOS.

So the question is does tinc really use ICMP to check remote hosts or 
use it's own UDP packets ?

A second one would be : does tinc check the remote host only when there 
is no traffic on the wire ? which, when I read the man, would tend to be 
yes ;-)

Thanks,

Cédric
