Server will by default listen on both IPv4 and IPv6. No way to only listen on one protocol right now. Use -L to only listen on a specific v6 address. IP address to use for raw mode is still IPv4 only. Use -n on server to make raw mode work from IPv6 clients, then they will get an IPv4 address from the server for raw mode. Tunnel data is still IPv4.

2009-06-01: 0.5.2 "WifiFree"
|
|
- Fixed client segfault on OS X, #57

|
|
- Fixed ENOTSOCK error on OS X and FreeBSD, #58.
|
|
|
|
2009-03-21: 0.5.1 "Boringo"
|
|
- Added initial Windows support, fixes #43.
|
|
- Added length check of autoprobe responses
|
|
- Refactored and added unit tests
|
|
- Added syslog logging for iodined on version and login packets
|
|
- Fixed segfault when encoding just one block, fixes #51.
|
|
The normal code was never affected by this.
|
|
- Added win32 code to read DNS server from system, fixes #45.
|
|
- Disabled password echo on win32, fixes #44.
|
|
- Fix encoding error making all autoprobing > 1024 bytes fail, #52.
|
|
- Increase default interface MTU to 1200.
|
|
- Fix autoprobing error making every third probe fail, set IP flag
|
|
Dont-Fragment where supported. Fixes #54.
|
|
- Added TAP32 version 0901 as accepted (#53).
|
|
|
|
2009-01-23: 0.5.0 "iPassed"
|
|
- Fixed segfault in server when sending version reject.
|
|
- Applied patch to make iodine build on BeOS R5-BONE and Haiku,
|
|
from Francois Revol. Still work to do to get tun device working.
|
|
- Added capability to forward DNS queries outside tunnel domain to
|
|
a nameserver on localhost. Use -b port to enable, fixes #31.
|
|
- iodined now replies to NS request on its own domain, fixes issue #33.
|
|
The destination IP address is sent as reply. Use -n to specify
|
|
a specific IP address to return (if behind NAT etc).
|
|
- Upstream data is now Base64 encoded if relay server preserves case and
|
|
supports the plus (+) character in domain names, fixes #16.
|
|
- Fixed problem in client when DNS trans. ID has highest bit set (#37)
|
|
- IP addresses are now assigned within the netmask, so iodined can
|
|
use any address for itself, fixes #28.
|
|
- Netmask size is now adjustable. Setting a small net will reduce the
|
|
number of users. Use x.x.x.x/n notation on iodined tunnel ip.
|
|
This fixes #27.
|
|
- Downstream data is now fragmented, and the fragment size is auto-
|
|
probed after login. Fixes #7. It only took a few years :)
|
|
- Enhanced the checks that validates incoming packets
|
|
- Fixed endless loop in fragment size autodetection, #39.
|
|
- Fixed broken hostname dot placing with specific lengths, #40.
|
|
|
|
2008-08-06: 0.4.2 "Opened Zone"
|
|
- Applied a few small patches from Maxim Bourmistrov and Gregor Herrmann
|
|
- Applied a patch for not creating and configuring the tun interface,
|
|
Debian bug #477692 by Vincent Bernat, controlled by -s switch
|
|
- Applied a security patch from Andrew Griffiths, use setgroups() to
|
|
limit the groups of the user
|
|
- Applied a patch to make iodine build on (Open)Solaris, from Albert Lee
|
|
Needs TUN/TAP driver http://www.whiteboard.ne.jp/~admin2/tuntap/
|
|
Still needs more code in tun.c for opening/closing the device
|
|
- Added option in server (-c) to disable IP/port checking on packets,
|
|
will hopefully help when server is behind NAT
|
|
- Fixed bug #21, now only IP address part of each packet is checked.
|
|
Should remove the need for the -c option and also work with
|
|
bugfixed DNS servers worldwide.
|
|
- Added -D option on server to enable debugging. Debug level 1 now
|
|
prints info about each RX/TX datagram.
|
|
