a56df1e06b - Allow ASN1 style keys to be in the config files.
Note: tinc ignores private key in the main config file, tinc.conf,

f8f1007bf4 Porting to SunOS 5.8:
- More #includes Linux doesn't seem to need
- Don't do unsetenv() on SunOS
- Use a replacement asprintf() in case the OS doesn't support it
It now compiles properly under SunOS.

f95cc86d0c Changed execution of tinc-up:
- Do not free() strings that have been putenv()d, see man page of the
  latter.
- Do not set IFNAME anymore, it appears that the ioctl to get the name of
  the interface does not work at all. Since it is set to NETNAME in case
  of tun/tap and it is known beforehand in case of ethertap, there is no
  need for it anyway... (though it would've simplified things).
2000-11-07 21:43:28 +00:00

owner's list and a global list. It is all fucked up but it probably
  works anyway, good enough for pre3 :).
2000-10-28 16:41:40 +00:00

c5737583c8 - Instead of logging an error when remote end closes the connection,
we print a nice message if appropiate debug level is set.
- If we get ADD_HOSTs or DEL_HOSTs for ourself, then connection lists
  are really messed up. We restart, and hope our problems go away.

18c85caac3 - New semantics for BASIC_INFO, ADD_HOST and DEL_HOST requests. This will
improve connection list consistency, ensures the tree property, and
  allows for recovery from situations where track of connections is lost.
2000-06-29 17:09:08 +00:00
Guus Sliepen
e8e7379311 - Removed all IP_ADDR_S macros, because gettext doesn't like them. Each
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  IP_ADDR_S has been replaced by %d.%d.%d.%d.

Guus Sliepen
7f7e158aae Large cleanup:
- 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

Guus Sliepen
d8e2f7104c First step for implementation of the "indirectdata" directive. This should
allow _leaf_ tincds to be behind firewalls.
The protocol has changed and is INCOMPATIBLE with previous versions. The
PROT_CURRENT value has been incremented.
