12 nodes do not know each other's ECDSA public key yet.
14 Version 1.1pre1 June 25 2011

106 Version 1.0.10 Oct 18 2009
108 * Fixed potential crashes during shutdown and (in rare conditions) when other
109 nodes disconnected from the VPN.
111 * Improved NAT handling: tinc now copes with mangled port numbers, and will
112 automatically fall back to TCP if direct UDP connection between nodes is not
113 possible. The TCPOnly option should not have to be used anymore.
115 * Allow configuration files with CRLF line endings to be read on UNIX.
117 * Disable old RSA keys when generating new ones, and raise the default size of

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

182 version 1.0.5 Nov 14 2006
184 * Lots of small fixes.

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