76 * Allow building tinc without LZO and/or Zlib.
78 * Clamp MSS of TCP packets in both directions.
80 * Experimental StrictSubnets, Forwarding and DirectOnly options,
81 giving more control over information and packets received from/sent to other

120 * Fixed potential crashes during shutdown and (in rare conditions) when other
121 nodes disconnected from the VPN.
123 * Improved NAT handling: tinc now copes with mangled port numbers, and will
124 automatically fall back to TCP if direct UDP connection between nodes is not
125 possible. The TCPOnly option should not have to be used anymore.
127 * Allow configuration files with CRLF line endings to be read on UNIX.
129 * Disable old RSA keys when generating new ones, and raise the default size of

146 features have been removed.

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

330 * Added a "switch" and a "hub" mode to allow bridging setups.
332 * Preliminary support for routing of IPv6 packets.
334 * Supports Linux, FreeBSD, OpenBSD and Solaris.
337 It looks like this might be the last release before 1.0.
340 version 1.0pre4 Jan 17 2001
342 * Updated documentation; the documentation now reflects the
343 configuration as it is.
345 * Some internal changes to make tinc scale better for large
346 networks, such as using AVL trees instead of linked lists for the
349 * RSA keys can be stored in separate files if needed. See the
350 documentation for more information.
352 * tinc has now been reported to run on Linux PowerPC and FreeBSD x86.
356 version 1.0pre3 Oct 31 2000
358 * The protocol has been redesigned, and although some details are
359 still under discussion, this is secure. Care has been taken to
360 resist most, if not all, attacks.
362 * Unfortunately this protocol is not compatible with earlier versions,
363 nor are earlier versions compatible with this version. Because the
364 older protocol has huge security flaws, we feel that not
365 implementing backwards compatibility is justified.
367 * Some data about the protocol:
369 * It uses public/private RSA keys for authentication (this is the
370 actual fix for the security hole).
372 * All cryptographic functions have been taken out of tinc, instead
373 it uses the OpenSSL library functions.
375 * Offers support for multiple subnets per tinc daemon.
377 * New is also the support for the universal tun/tap device. This
378 means better portability to FreeBSD and Solaris.
380 * tinc is tested to compile on Solaris, Linux x86, Linux alpha.
382 * tinc now uses the OpenSSL library for cryptographic operations.
383 More information on getting and installing OpenSSL is in the manual.
384 This also means that the GMP library is no longer required.
386 * Further, thanks to Enrique Zanardi, we have Spanish messages; Matias
387 Carrasco provided us with a Spanish translation of the manual.
390 What still needs to be done before 1.0:
392 * Documentation. Especially since the protocol has changed, and a lot
393 of configuration directives have been added.
398 version 1.0pre2 May 31 2000
400 * This version has been internationalized; and a Dutch translation has
403 * Two configuration variables have been added:
404 * VpnMask - the IP network mask for the entire VPN, not just our
405 subnet (as given by MyVirtualIP). The Redhat and Debian packages
406 use this variable in their system startup scripts, but it is
408 * Hostnames - if set to `yes', look up the names of IP addresses
409 trying to connect to us. Default set to `no', to prevent lockups
412 * The system startup scripts for Debian and Redhat use
413 /etc/tinc/nets.boot to find out which networks need to be started
416 * Fixes to prevent denial of service attacks by sending random data
417 after connecting (and even when the connection has been established),
418 either random garbage or just nonsensical protocol fields.
420 * tinc will retry to connect upon startup, does not quit if it doesn't
423 * Hosts that are disconnected implicitly if we lose a connection get
424 deleted from the internal list, to prevent hogging eachother with
425 add and delete requests when the connection is restored.
428 What still needs to be done before 1.0:
431 * Failover ConnectTo lines, try another one if the first doesn't work.
