connection now has two hostnames: real_hostname (replacing the old),
and vpn_hostname. In those places where hostnames really aren't usefull
IP_ADDR_S has been replaced by %d.%d.%d.%d.
- Removed hostname lookup (it blocks, and you can always do it yourself)
- Reorganized debug levels (after hints from Axel M�ller):
0 Startup message and errors
1 Connection logging
2 Meta protocol information
3 Verbose meta protocol (includes copy of transmitted requests)
4 Packet information (logs transmission/errors of UDP packets)
5 Verbose packet information (every single byte, not implemented yet
to protect ourselves from filling up /var/log directories)
- Made log messages more consistent
allow _leaf_ tincds to be behind firewalls.
The protocol has changed and is INCOMPATIBLE with previous versions. The
PROT_CURRENT value has been incremented.
to send, we don't need to check if the connection is still alive.
Furthermore, if we receive any kind of data from the other end, we know
it's alive, so we don't need to check it either. So, PING requests are
only sent if we send packets but there is no response.
furthermore this version does NOT work yet because of a problem with
sending keys (these should be converted to base36 or something like that).
It is possible to telnet to the tinc daemon now and type some commands
by hand though :).
