52b842f807 - Fixed all debug levels.

9f64499e40 - tinc now really does public/private key encryption! It even works, whee! 2000-10-20 15:34:38 +00:00
Guus Sliepen
20301888b7 - More fixing. Tinc daemons can now even create activated connections. 2000-10-16 19:04:47 +00:00

bb3d18d56f - Fixing little things

  after the ACKs).

e9635ae38e - Second fixing-things pass: it even links now. 
- Lots of FIXME comments added to the source code.
 2000-10-14 17:04:16 +00:00

183a8edd22 - Fixing-things pass: every source file compiles into an object file now, 
but linking tincd does not work yet (must link with openssl libs and
  define some missing functions).

6e39481d8f - Generalized config file parsing to support multiple configuration trees. 2000-10-11 13:42:52 +00:00

c78a204f06 - Added meta.c which contains functions to send, receive and broadcast 
metadata. It will also handle encryption and decryption, and possibly
  compression and checksumming.
- Moved request dispatcher to protocol.c.

361690b18c - Removed options "string" stuff. It was a bad idea... 
- free() everything that is allocated.

3cfc9424f2 - Moved TCP packet reception to meta handler: less kludgy and less buggy! 2000-08-08 17:07:48 +00:00

- Made TCPonly work :)
 2000-08-07 16:27:29 +00:00

fdc6a2f106 - Added experimental hackish tunneling-over-TCP support. 
Just use TCPonly = true in the configuration file.

1a1ebefd57 - Made tinc even more silent if no -d flag is given at all. 2000-06-30 21:03:51 +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.

0f9ad1f047 - Fixed memory leak. 
- Implemented SIGHUP configuration file reloading.
- Other small changes.

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.

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  IP_ADDR_S has been replaced by %d.%d.%d.%d.

8c6c60adf3 - Fixed a message in nl.po 
- Woops, we forgot to send our connection list to our uplink when we
  connect to it... Fixed.

ea40d3f1a0 - Fixed some spelling errors. 
- Paar zpelvautjes gerepareerd, en de Nederlandse vertaling weer bij de
  tijd gebracht.

4aeaea5e59 - Improved handling of errors on connection attempts. 2000-06-27 20:10:48 +00:00
Guus Sliepen
4faed1b854 - Fixed KEY_CHANGED notification. A lot of notify_others() calls were 
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
04cb206298 - Moved all connection messages to debug level 1, without -d's only the 
startup message will be logged.
- Fixed DEL_HOST rebound.

783c829861 - Indirectdata finally REALLY REALLY works now! 
- More precise debug messages
 2000-06-26 19:39:34 +00:00
Guus Sliepen
b3681ebf6c Fixes some hostlookups. Fixes indirectdata for real now (hopefully). 2000-06-26 17:20:58 +00:00

a473ece8a0 - More verbose connection list 
- Added "myself" as hostname when logging indirect ADD_HOSTs
 2000-06-25 16:39:17 +00:00

f1f901112e Hostlookup() is actually being called now. 2000-06-25 16:20:27 +00:00

54079bdf03 Hostnames are back! 2000-06-25 16:01:12 +00:00

e4b586ed07 - Log possible spoofing attacks. 
- Don't broadcast DEL_HOSTs for hosts that haven't been activated yet.
- If a host sends a TERMREQ, deactivate them.
 2000-06-25 15:45:09 +00:00

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
PROT_CURRENT value has been incremented.

17fa07510a Only accept an ADD_HOST request for a host that already exists in our conn_list if the nexthop field matches the sender. This is a workaround for older clients. 2000-05-30 21:36:16 +00:00
