1eedf54681 - Use only one socket for all UDP traffic (for compatibility) 
- Write pidfile again after detaching
- Check OS (for handling FreeBSD/Solaris tun/tap stuff)

cf49b2c064 Another big & bad commit: 
- Added some extra search functions to rbl routines
- Fix subnet_lookup()
- Reorder some syslog messages to make more sense
- daemon() is back
- Don't let scripts execute in parallel (gives race conditions, and
  anyway something MIGHT just be configured which is necessary for further
  execution of tinc itself)
- Accidently merged check_child() with execute_script().
- Small fixes

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.

7d0f82bd4b - Open UDP connection for all known hosts. Comments please. 2000-11-07 22:02:14 +00:00
Guus Sliepen
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).

698191fd2f - Prepended config_ to all configuration option names, because it confused

d47d5932a3 - Updated subnet list handling. Subnets are added to two lists now, the 
owner's list and a global list. It is all fucked up but it probably
  works anyway, good enough for pre3 :).

73f7efddd7 - Removed last reference to genauth from Makefile.am 
- Tinc spawns tinc-up and tinc-down scripts which can be used to configure
