f8f1007bf4 Porting to SunOS 5.8: 
- More #includes Linux doesn't seem to need
- Don't do unsetenv() on 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).
 2000-11-07 21:43:28 +00:00

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

  define some missing functions).
 2000-10-11 22:01:02 +00:00

Guus Sliepen
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.
 2000-06-30 12:41:06 +00:00
Guus Sliepen
24874d0806 - Removed segfault bug in conf.c (must have been there for ages!)

 2000-06-29 19:47:04 +00:00
Guus Sliepen
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  IP_ADDR_S has been replaced by %d.%d.%d.%d.
 2000-06-29 13:04:15 +00:00

wrong (first two arguments swapped). Should probably be doublechecked.
- Don't retry to connect to hosts with different protocol versions.
 2000-06-27 12:58:04 +00:00
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

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

e4ff969a98 Fix for a DoS attack: 
A remote user could telnet to the tinc daemon and type only this line:
 61 6 00000000/00000000:28f
 This would deny any packets to be sent to other tinc networks (except
 for to the hosts that run tincd's themselves). Solution is to skip
 hosts in lookup_conn() that have not been activated yet.
Fixed potential conn_list table corruption:
 If a new connection is accepted but a connection with the same subnet
 would already exist in the connection list, the OLD connection is
 terminated.

e20e143f1e Changed ping behaviour (backwards compatible). If we don't have any data 
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.
