Oops, silly me.
My name is Arno van der Kolk, by the way. ;)


I have been reading some more through the mail archive and have enabled
debug level 5. It seems both hosts are ping-ponging quite nicely.

However, I have also found out the following:

Client:~$ ping 10.0.0.1
PING 10.0.0.1 (10.0.0.1): 56 data bytes

--- 10.0.0.1 ping statistics ---
3 packets transmitted, 0 packets received, 100% packet loss


Generates the following in the log:

Jul  7 23:21:53 Client tinc.iwan[273]: Read packet of 249 bytes from Linux
ethertap device
Jul  7 23:21:53 Client tinc.iwan[273]: Sending packet of 249 bytes to Client
(MYSELF)
Jul  7 23:21:53 Client tinc.iwan[273]: Packet is looping back to us!

This goes for both hosts.

The duplicate entries for the tap0 device are because of some experimenting,
normally there's only one (!! without a gateway !!).

Here's also the output of ifconfig...

Again, any help would be appreciated because I still don't know what the
problem is; everything looks alright to me. Thanks.
