305505f5ec Remember sockaddrs of listening sockets, use appropriate one when sending 
UDP packets.

14979f835d - Global time_t now, so that we don't have to call time() too often. 
- MAC addresses expire after a time configurable by MACExpire (default 600
  seconds)

c2b738e7b5 If "PriorityInheritance = yes" is specified in tinc.conf, the value of the 
TOS field of the tunneled packets will be passed on to the UDP packets tinc
sends out.

23fda5688e - Change SA_LEN to SALEN, former one is already defined on some platforms. 
- Use SALEN everywhere appropriate.

dbc5b5bb5e - Use gai_strerror() where appropriate 
- Clear hints before using them with getaddrinfo()
- Use sa_len on platforms that support them

c2b9c06062 - Non-blocking connect()s. 
- Socket handling revamped to use sockaddr_t.
- tinc can now tunnel over IPv6.
- Handle all addresses and subnets in network byte order.
  Only convert them when they need to be printed.
- IPv6 subnets bigger than /128 now work.
- Use %s and strerror(errno) instead of %m.

82e3837109 Big bad commit: 
- Transition to new node/vertex/connection structures
- Use new configuration handling everywhere
- Linux tun/tap device handling cleanup
- Start of IPv6 support in route.c

It compiles, but it won't link.

acb853205d Updated terminate_connection() so you can choose if DEL_HOSTs should be 
sent or not.

4f9dad0972 - tinc can now act as a switch or a hub too (as opposed to a router only) 
- cleaner initialisation of "UNKNOWN" and "MYSELF" names

fcf869cd42 TCPonly now works (in a relatively clean way too). 2001-05-25 11:54:28 +00:00

e4f3d93ec6 - s/ip_t/ipv4_t/g 
- Add "salt" to the beginning of UDP packets. Replaces length field which
  is not useful anyway.

34f9e6cf2d - route.c is now used to determine destination 
- flags are removed, since they were not used at all. Use options instead.
- indirectdata works now, tcponly almost...
- made functions that don't return useful information void

e1707f7739 - Don't even think about using sscanf with %as anymore 
- Allow keys to be inside the config files or in a seperate file
- Small fixes

a0f7af3ed7 New function read_rsa_public_key(); 
In net.c/setup_myself deleted old code to read the public key (which
is now implicitly read in together with the private key).

698191fd2f - Prepended config_ to all configuration option names, because it confused 
everything (including myself).
- Use connection oriented UDP sockets for both incoming and outgoing
  packets.

- Added support for tun/tap driver (autodetect!)
- More sophisticated checkpoint functionality
- Updated dutch translation

e9635ae38e - Second fixing-things pass: it even links now. 
- Lots of FIXME comments added to the source code.

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).

950fb8e916 Big and bad commit of my current tree... 
- Added seperate file for connection list handling
- Updating everything to use connlist, meta and subnet files
- Removed dependency on libgmp
- Lots of other stuff...

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

b6997b0050 - Lots o' buglets fixed (-Wall helps) 
- Made TCPonly work :)

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

1b28f88808 - Removed a single unused bit from status_bits_t. 2000-07-01 07:49:21 +00:00

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.

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.

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.

by one byte.
