Hi,
I'm trying to get tinc running on my crux linux machines (with self compiled
kernels). On one box, I got it runnig straight-forwardly, on the other, it
starts without errors, but is unable to actually reach any of my other tinc
instances: The log suggests, that the connection is established, MTU probes
and pings/pongs are sent and received, but a ping on the tun ip of the other
node fails.
My suspicion is, that I'm missing some kernel parameters (I had to add
CONFIG_TUN to make it start at all, for example).
Is there any documentation on what kernel parameters are needed for
configuration with tun?
However, maybe the error is somewhere completely else, because upon
investigation I just noticed, that one of my *other* machines (running
archlinux32, not crux) is also unable to connect and shows similar symptoms.
Any idea, how to investigate this further?
regards,
Erich
Hi,
just some follow-up: I played around a little bit with wireshark, tcpdump
and ping and noticed, that pings were actually running back and forth
successfully. Then I looked at my config again and noticed, that I had
missed the "Subnet = $ip/32" line in my own hosts/... config file - adding
this fixed the problem :-)
regards,
Erich
