51 * Allow building tinc without LZO and/or Zlib.
53 * Clamp MSS of TCP packets in both directions.
55 * Experimental StrictSubnets, Forwarding and DirectOnly options,
56 giving more control over information and packets received from/sent to other
59 * Ensure tinc never sends symbolic names for ports over the wire.
61 Version 1.0.12 Feb 3 2010
63 * Really allow fast roaming of hosts to other nodes in a switched VPN.
65 * Fixes missing or incorrect environment variables when calling host-up/down
66 and subnet-up/down scripts in some cases.
68 * Allow port to be specified in Address statements.
70 * Clamp MSS of TCP packets to the discovered path MTU.

76 Version 1.0.11 Nov 1 2009
78 * Fixed potential crash when the HUP signal is sent.
80 * Fixes handling of weighted Subnets in switch and hub modes, preventing
81 unnecessary broadcasts.

86 * Improvements to the PMTU discovery code, especially on Windows.
88 * Use UDP again in certain cases where 1.0.10 was too conservative and fell
89 back to TCP unnecessarily.
91 * Allow fast roaming of hosts to other nodes in a switched VPN.
93 Version 1.0.10 Oct 18 2009
95 * Fixed potential crashes during shutdown and (in rare conditions) when other
96 nodes disconnected from the VPN.
98 * Improved NAT handling: tinc now copes with mangled port numbers, and will
99 automatically fall back to TCP if direct UDP connection between nodes is not
100 possible. The TCPOnly option should not have to be used anymore.
102 * Allow configuration files with CRLF line endings to be read on UNIX.
104 * Disable old RSA keys when generating new ones, and raise the default size of
105 new RSA keys to 2048 bits.

110 * Tinc can now drop privileges and/or chroot itself.
112 * The TunnelServer code now just ignores information from clients instead of
115 * Improved performance on Windows by using the new ProcessPriority option and
116 by making the handling of packets received from the TAP-Win32 adapter more
119 * Code cleanups: tinc now follows the C99 standard, copyright headers have
120 been updated to include patch authors, checkpoint tracing and localisation
121 features have been removed.

125 Thanks to Florian Forster, Grzegorz Dymarek and especially Michael Tokarev for
126 their contributions to this version of tinc.

169 version 1.0.5 Nov 14 2006
171 * Lots of small fixes.

312 It looks like this might be the last release before 1.0.
315 version 1.0pre4 Jan 17 2001
317 * Updated documentation; the documentation now reflects the
318 configuration as it is.
320 * Some internal changes to make tinc scale better for large
321 networks, such as using AVL trees instead of linked lists for the
324 * RSA keys can be stored in separate files if needed. See the
325 documentation for more information.
327 * tinc has now been reported to run on Linux PowerPC and FreeBSD x86.
331 version 1.0pre3 Oct 31 2000
333 * The protocol has been redesigned, and although some details are
334 still under discussion, this is secure. Care has been taken to
335 resist most, if not all, attacks.
337 * Unfortunately this protocol is not compatible with earlier versions,
338 nor are earlier versions compatible with this version. Because the
339 older protocol has huge security flaws, we feel that not
340 implementing backwards compatibility is justified.
342 * Some data about the protocol:
344 * It uses public/private RSA keys for authentication (this is the
345 actual fix for the security hole).
347 * All cryptographic functions have been taken out of tinc, instead
348 it uses the OpenSSL library functions.
350 * Offers support for multiple subnets per tinc daemon.
352 * New is also the support for the universal tun/tap device. This
353 means better portability to FreeBSD and Solaris.
355 * tinc is tested to compile on Solaris, Linux x86, Linux alpha.
357 * tinc now uses the OpenSSL library for cryptographic operations.
358 More information on getting and installing OpenSSL is in the manual.
359 This also means that the GMP library is no longer required.
361 * Further, thanks to Enrique Zanardi, we have Spanish messages; Matias
362 Carrasco provided us with a Spanish translation of the manual.
365 What still needs to be done before 1.0:
367 * Documentation. Especially since the protocol has changed, and a lot
368 of configuration directives have been added.
373 version 1.0pre2 May 31 2000
375 * This version has been internationalized; and a Dutch translation has
378 * Two configuration variables have been added:
379 * VpnMask - the IP network mask for the entire VPN, not just our
380 subnet (as given by MyVirtualIP). The Redhat and Debian packages
381 use this variable in their system startup scripts, but it is
383 * Hostnames - if set to `yes', look up the names of IP addresses
384 trying to connect to us. Default set to `no', to prevent lockups
387 * The system startup scripts for Debian and Redhat use
388 /etc/tinc/nets.boot to find out which networks need to be started
391 * Fixes to prevent denial of service attacks by sending random data
392 after connecting (and even when the connection has been established),
393 either random garbage or just nonsensical protocol fields.
395 * tinc will retry to connect upon startup, does not quit if it doesn't
398 * Hosts that are disconnected implicitly if we lose a connection get
399 deleted from the internal list, to prevent hogging eachother with
400 add and delete requests when the connection is restored.
403 What still needs to be done before 1.0:
406 * Failover ConnectTo lines, try another one if the first doesn't work.
