Version 1.1pre2 Juli 17 2011 * .cookie files are renamed to .pid files, which are compatible with 1.0.x. * Experimental protocol enhancements that can be enabled with the option ExperimentalProtocol = yes: * Ephemeral ECDH key exchange will be used for both the meta protocol and UDP session keys. * Key exchanges are signed with ECDSA. * ECDSA public keys are automatically exchanged after RSA authentication if nodes do not know each other's ECDSA public key yet. Version 1.1pre1 June 25 2011 * Control interface allows control of a running tinc daemon. Used by: * tincctl, a commandline utility * tinc-gui, a preliminary GUI implemented in Python/wxWidgets * Code cleanups and reorganization. * Repleacable cryptography backend, currently supports OpenSSL and libgcrypt. * Use libevent to handle I/O events and timeouts. * Use splay trees instead of AVL trees to manage internal datastructures. Thanks to Scott Lamb and Sven-Haegar Koch for their contributions to this version of tinc. Version 1.0.16 July 23 2011 * Fixed a performance issue with TCP communication under Windows. * Fixed code that, during network outages, would cause tinc to exit when it thought two nodes with identical Names were on the VPN. Version 1.0.15 June 24 2011 * Improved logging to file. * Reduced amount of process wakeups on platforms which support pselect(). * Fixed ProcessPriority option under Windows. Thanks to Loïc Grenié for his contribution to this version of tinc. Version 1.0.14 May 8 2011 * Fixed reading configuration files that do not end with a newline. Again. * Allow arbitrary configuration options being specified on the command line. * Allow all options in both tinc.conf and the local host config file. * Configurable replay window, UDP send and receive buffers for performance tuning. * Try harder to get UDP communication back after falling back to TCP. * Initial support for attaching tinc to a VDE switch. * DragonFly BSD support. * Allow linking with OpenSSL 1.0.0. Thanks to Brandon Black, Julien Muchembled, Michael Tokarev, Rumko and Timothy Redaelli for their contributions to this version of tinc. Version 1.0.13 Apr 11 2010 * Allow building tinc without LZO and/or Zlib. * Clamp MSS of TCP packets in both directions. * Experimental StrictSubnets, Forwarding and DirectOnly options, giving more control over information and packets received from/sent to other nodes. * Ensure tinc never sends symbolic names for ports over the wire. Version 1.0.12 Feb 3 2010 * Really allow fast roaming of hosts to other nodes in a switched VPN. * Fixes missing or incorrect environment variables when calling host-up/down and subnet-up/down scripts in some cases. * Allow port to be specified in Address statements. * Clamp MSS of TCP packets to the discovered path MTU. * Let two nodes behind NAT learn each others current UDP address and port via a third node, potentially allowing direct communications in a similar way to STUN. Version 1.0.11 Nov 1 2009 * Fixed potential crash when the HUP signal is sent. * Fixes handling of weighted Subnets in switch and hub modes, preventing unnecessary broadcasts. * Works around a MinGW bug that caused packets to Windows nodes to always be sent via TCP. * Improvements to the PMTU discovery code, especially on Windows. * Use UDP again in certain cases where 1.0.10 was too conservative and fell back to TCP unnecessarily. * Allow fast roaming of hosts to other nodes in a switched VPN. Version 1.0.10 Oct 18 2009 * Fixed potential crashes during shutdown and (in rare conditions) when other nodes disconnected from the VPN. * Improved NAT handling: tinc now copes with mangled port numbers, and will automatically fall back to TCP if direct UDP connection between nodes is not possible. The TCPOnly option should not have to be used anymore. * Allow configuration files with CRLF line endings to be read on UNIX. * Disable old RSA keys when generating new ones, and raise the default size of new RSA keys to 2048 bits. * Many fixes in the path MTU discovery code, especially when Compression is being used. * Tinc can now drop privileges and/or chroot itself. * The TunnelServer code now just ignores information from clients instead of disconnecting them. * Improved performance on Windows by using the new ProcessPriority option and by making the handling of packets received from the TAP-Win32 adapter more efficient. * Code cleanups: tinc now follows the C99 standard, copyright headers have been updated to include patch authors, checkpoint tracing and localisation features have been removed. * Support for (jailbroken) iPhone and iPod Touch has been added. Thanks to Florian Forster, Grzegorz Dymarek and especially Michael Tokarev for their contributions to this version of tinc. Version 1.0.9 Dec 26 2008 * Fixed tinc as a service under Windows 2003. * Fixed reading configuration files that do not end with a newline. * Fixed crashes in situations where hostnames could not be resolved or hosts would disconnect at the same time as session keys were exchanged. * Improved default settings of tun and tap devices on BSD platforms. * Make IPv6 sockets bind only to IPv6 on Linux. * Enable path MTU discovery by default. * Fixed a memory leak that occured when connections were closed. Thanks to Max Rijevski for his contributions to this version of tinc. Version 1.0.8 May 16 2007 * Fixed some memory and resource leaks. * Made network sockets non-blocking under Windows. Thanks to Scott Lamb and "dnk" for their contributions to this version of tinc. Version 1.0.7 Jan 5 2007 * Fixed a bug that caused slow network speeds on Windows. * Fixed a bug that caused tinc unable to write packets to the tun device on OpenBSD. Version 1.0.6 Dec 18 2006 * More flexible detection of the LZO libraries when compiling. * Fixed a bug where broadcasts in switch and hub modes sometimes would not work anymore when part of the VPN had become disconnected from the rest. version 1.0.5 Nov 14 2006 * Lots of small fixes. * Broadcast packets no longer grow in size with each hop. This should fix switch mode (again). * Generic host-up and host-down scripts. * Optionally dump graph in graphviz format to a file or a script. * Support LZO 2.0 and later. Thanks to Scott Lamb for his contributions to this version of tinc. version 1.0.4 May 4 2005 * Fix switch and hub modes. * Optionally start scripts when a Subnet becomes (un)reachable. version 1.0.3 Nov 11 2004 * Show error message when failing to write a PID file. * Ignore spaces at end of lines in config files. * Fix handling of late packets. * Unify BSD tun/tap device handling. This allows IPv6 on tun devices and anything on tap devices as long as the underlying OS supports it. * Handle IPv6 on Solaris tun devices. * Allow tinc to work properly under Windows XP SP2. * Allow VLAN tagged Ethernet frames in switch and hub mode. * Experimental PMTUDiscovery, TunnelServer and BlockingTCP options. version 1.0.2 Nov 8 2003 * Fix address and hostname resolving under Windows. * Remove warnings about non-existing scripts and unsupported address families. * Use the event logger under Windows. * Fix quoting of filenames and command line arguments under Windows. * Strict checks for length incoming network packets and return values of cryptographic functions, * Fix a bug in metadata handling that made the tinc daemon abort. version 1.0.1 Aug 14 2003 * Allow empty lines in config files. * Fix handling of spaces and backslashes in filenames under native Windows. * Allow scripts to be executed under native Windows. * Update documentation, make it less Linux specific. version 1.0 Aug 4 2003 * Lots of small bugfixes and code cleanups. * Throughput doubled and latency reduced. * Added support for LZO compression. * No need to set MAC address or disable ARP anymore. * Added support for Windows 2000 and XP, both natively and in a Cygwin environment. version 1.0pre8 Sep 16 2002 * More fixes for subnets with prefixlength undivisible by 8. * Added support for NetBSD and MacOS/X. * Switched from undirected graphs to directed graphs to avoid certain race conditions and improve scalability. * Generalized broadcasting and forwarding of protocol messages. * Cleanup of source code. version 1.0pre7 Apr 7 2002 * Don't do blocking read()s when getting a signal. * Remove RSA key checking code, since it sometimes thinks perfectly good RSA keys are bad. * Fix handling of subnets when prefixlength isn't divisible by 8. version 1.0pre6 Mar 27 2002 * Improvement of redundant links: * Non-blocking connects. * Protocol broadcast messages can no longer go into an infinite loop. * Graph algorithm updated to look harder for direct connections. * Good support for routing IPv6 packets over the VPN. Works on Linux, FreeBSD, possibly OpenBSD but not on Solaris. * Support for tunnels over IPv6 networks. Works on all supported operating systems. * Optional compression of UDP connections using zlib. * Optionally let UDP connections inherit TOS field of tunneled packets. * Optionally start scripts when certain hosts become (un)reachable. version 1.0pre5 Feb 9 2002 * Security enhancements: * Added sequence number and optional message authentication code to the packets. * Configurable encryption cipher and digest algorithms. * More robust handling of dis- and reconnects. * Added a "switch" and a "hub" mode to allow bridging setups. * Preliminary support for routing of IPv6 packets. * Supports Linux, FreeBSD, OpenBSD and Solaris. It looks like this might be the last release before 1.0. version 1.0pre4 Jan 17 2001 * Updated documentation; the documentation now reflects the configuration as it is. * Some internal changes to make tinc scale better for large networks, such as using AVL trees instead of linked lists for the connection list. * RSA keys can be stored in separate files if needed. See the documentation for more information. * tinc has now been reported to run on Linux PowerPC and FreeBSD x86. version 1.0pre3 Oct 31 2000 * The protocol has been redesigned, and although some details are still under discussion, this is secure. Care has been taken to resist most, if not all, attacks. * Unfortunately this protocol is not compatible with earlier versions, nor are earlier versions compatible with this version. Because the older protocol has huge security flaws, we feel that not implementing backwards compatibility is justified. * Some data about the protocol: * It uses public/private RSA keys for authentication (this is the actual fix for the security hole). * All cryptographic functions have been taken out of tinc, instead it uses the OpenSSL library functions. * Offers support for multiple subnets per tinc daemon. * New is also the support for the universal tun/tap device. This means better portability to FreeBSD and Solaris. * tinc is tested to compile on Solaris, Linux x86, Linux alpha. * tinc now uses the OpenSSL library for cryptographic operations. More information on getting and installing OpenSSL is in the manual. This also means that the GMP library is no longer required. * Further, thanks to Enrique Zanardi, we have Spanish messages; Matias Carrasco provided us with a Spanish translation of the manual. What still needs to be done before 1.0: * Documentation. Especially since the protocol has changed, and a lot of configuration directives have been added. version 1.0pre2 May 31 2000 * This version has been internationalized; and a Dutch translation has been included. * Two configuration variables have been added: * VpnMask - the IP network mask for the entire VPN, not just our subnet (as given by MyVirtualIP). The Redhat and Debian packages use this variable in their system startup scripts, but it is ignored by tinc. * Hostnames - if set to `yes', look up the names of IP addresses trying to connect to us. Default set to `no', to prevent lockups during lookups. * The system startup scripts for Debian and Redhat use /etc/tinc/nets.boot to find out which networks need to be started during system boot. * Fixes to prevent denial of service attacks by sending random data after connecting (and even when the connection has been established), either random garbage or just nonsensical protocol fields. * tinc will retry to connect upon startup, does not quit if it doesn't work the first time. * Hosts that are disconnected implicitly if we lose a connection get deleted from the internal list, to prevent hogging eachother with add and delete requests when the connection is restored. What still needs to be done before 1.0: * Documentation. * Failover ConnectTo lines, try another one if the first doesn't work. version 1.0pre1 May 12 2000 * New meta-protocol * Various other bugfixes * Documentation updates version 0.3.3 Feb 9 2000 * Fixed bug that made tinc stop working with latest kernels (Guus Sliepen) * Updated the manual version 0.3.2 Nov 12 1999 * no more `Invalid filedescriptor' when working with multiple connections * forward unknown packets to uplink version 0.3.1 Oct 20 1999 * fixed a bug where tinc would exit without a trace version 0.3 Aug 20 1999 * pings now work immediately * all packet sizes get transmitted correctly version 0.2.26 Aug 15 1999 * fixed some remaining bugs * --sysconfdir works with configure * last version before 0.3 version 0.2.25 Aug 8 1999 * improved stability, going towards 0.3 now. version 0.2.24 Aug 7 1999 * added key aging, there's a new config variable, KeyExpire. * updated man and info pages version 0.2.23 Aug 5 1999 * all known bugs fixed, this is a candidate for 0.3 version 0.2.22 Apr 11 1999 * multiconnection thing is now working nearly perfect :) version 0.2.21 Apr 10 1999 * You shouldn't notice a thing, but a lot has changed wrt key management - except that it refuses to talk to versions < 0.2.20 version 0.2.20 version 0.2.19 Apr 3 1999 * don't install a libcipher.so version 0.2.18 Apr 3 1999 * blowfish library dynamically loaded upon execution * included Eric Young's IDEA library version 0.2.17 Apr 1 1999 * tincd now re-executes itself in case of a segmentation fault. version 0.2.16 Apr 1 1999 * wrote tincd.conf(5) man page, which still needs a lot of work. * config file now accepts and tolerates spaces, and any integer base for integer variables, and better error reporting. See doc/tincd.conf.sample for an example. version 0.2.15 Mar 29 1999 * fixed bugs version 0.2.14 Feb 10 1999 * added --timeout flag and PingTimeout configuration * did some first syslog cleanup work version 0.2.13 Jan 23 1999 * bugfixes version 0.2.12 Jan 23 1999 * fixed nauseating bug so that it would crash whenever a connection got lost version 0.2.11 Jan 22 1999 * framework for multiple connections has been done * simple manpage for tincd version 0.2.10 Jan 18 1999 * passphrase support added version 0.2.9 Jan 13 1999 * bugs fixed. version 0.2.8 Jan 11 1999 * a reworked protocol version * a ping/pong system * more reliable networking code * automatic reconnection * still does not work with more than one connection :) * strips MAC addresses before sending, so there's less overhead, and less redundancy version 0.2.7 Jan 3 1999 * several updates to make extending more easy. version 0.2.6 Dec 20 1998 * Point-to-Point connections have been established, including blowfish encryption and a secret key-exchange. version 0.2.5 Dec 16 1998 * Project renamed to tinc, in honour of TINC. version 0.2.4 Dec 16 1998 * now it really does ;) version 0.2.3 Nov 24 1998 * it sort of works now version 0.2.2 Nov 20 1998 * uses GNU gmp. version 0.2.1 Nov 14 1998 * Bare version.
