ab90fa9bd1 Document and clean up MAC address expiry. 2002-03-01 14:25:10 +00:00
Guus Sliepen
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)

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.

f64b41a73b Get rid of sys/signal.h. 2002-02-12 14:36:45 +00:00
Guus Sliepen
d9a62c6354 Added support for packet compression, thanks to Mark Glines. 
Add "Compression = <level>" to the host config files, where level can be
0 (off), or any integer between 1 (fast) and 9 (best).

Guus Sliepen
24a2c7e51a Not only keep track of nexthop, but also of lastbutonehop. If destination cl 
wants indirectdata, send it to the lastbutonehop instead, unless it too has
requested so, and so on.

12f6b80429 Added purge_tree for connection_t's which are no longer in the connection, 
active or id trees, but which may still be referenced. This tree is flushed
when it is safe, this replaces purge_connection_tree().

Also lots of bugfixes related to the new trees.

5d34503574 Execute tinc-down BEFORE tap device is closed. This is a. more symmetric 
(tinc-up is started after tap device is opened) and b. is needed for
tun/tap device, where the interface does not exist anymore after the
device file is closed.

04ec0b82ab - Solaris compile fixes 
- Set mymac to broadcast MAC so that ifconfig hw ether <...> is really not
  needed anymore.
- Forwarding of indirect packets when in switch mode (because the kernel
  will not do it for us then).

7bd7f5b436 You can now put an option "Mode" in tinc.conf, and choose from: 
- Mode = router (default, work like tinc has always worked)
- Mode = switch (work like a switch)
- Mode = hub    (work like a hub, broadcasting everything)
 2001-06-05 19:39:54 +00:00

4f9dad0972 - tinc can now act as a switch or a hub too (as opposed to a router only)

Guus Sliepen
a56df1e06b - Allow ASN1 style keys to be in the config files. 
Note: tinc ignores private key in the main config file, tinc.conf,
  because it should really be in a separate file.
- When generating new keys, check if name is known and by default append
  the public key to the host configuration file (otherwise rsa_key.pub).

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.
 2000-11-08 00:10:50 +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

73f7efddd7 - Removed last reference to genauth from Makefile.am 
- Tinc spawns tinc-up and tinc-down scripts which can be used to configure
  the network device. The environment variable IFNAME is set to the name
  of the interface.

bb3d18d56f - Fixing little things 
- Two tinc daemons can connect to eachother now (but they disconnect right
  after the ACKs).

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).

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.

Guus Sliepen
4dde583bc9 - Use strerror() instead of sys_errlist[] for increased portability 
(Needed for SunOS)
 2000-09-06 11:49:05 +00:00
Guus Sliepen
9acd4379f7 - Added two extra configuration options, Interface and InterfaceIP, to 
bind the listen socket to a network device or a specific IP.
 2000-08-09 14:02:16 +00:00
Guus Sliepen
f6d79366b3 - Reinstated O_NONBLOCK for meta socket 
- Set SO_KEEPALIVE on meta socket

3cfc9424f2 - Moved TCP packet reception to meta handler: less kludgy and less buggy! 2000-08-08 17:07:48 +00:00
Guus Sliepen
ff87f385c3 Removed calling add_queue for tcponly packets. 2000-08-08 13:47:57 +00:00

b6997b0050 - Lots o' buglets fixed (-Wall helps) 
- Made TCPonly work :)
 2000-08-07 16:27:29 +00:00
Guus Sliepen
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
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

24874d0806 - Removed segfault bug in conf.c (must have been there for ages!) 
- Made main_loop() signal proof
- #defined MAXTIMEOUT (15 minutes)
- If something really really bad happens, close all connections, wait
  for MAXTIMEOUT seconds, and then restart tinc

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

 2000-06-29 19:47:04 +00:00

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.
