18 * Make IPv6 sockets bind only to IPv6 on Linux.
20 * Enable path MTU discovery by default.
22 * Fixed a memory leak that occured when connections were closed.
24 Version 1.0.8 May 16 2007

44 version 1.0.5 Nov 14 2006
46 * Lots of small fixes.
48 * Broadcast packets no longer grow in size with each hop. This should
49 fix switch mode (again).

178 * Added a "switch" and a "hub" mode to allow bridging setups.
180 * Preliminary support for routing of IPv6 packets.
182 * Supports Linux, FreeBSD, OpenBSD and Solaris.
185 It looks like this might be the last release before 1.0.
188 version 1.0pre4 Jan 17 2001
190 * Updated documentation; the documentation now reflects the
191 configuration as it is.
193 * Some internal changes to make tinc scale better for large
194 networks, such as using AVL trees instead of linked lists for the
197 * RSA keys can be stored in separate files if needed. See the
198 documentation for more information.
200 * tinc has now been reported to run on Linux PowerPC and FreeBSD x86.
204 version 1.0pre3 Oct 31 2000
206 * The protocol has been redesigned, and although some details are
207 still under discussion, this is secure. Care has been taken to
208 resist most, if not all, attacks.
210 * Unfortunately this protocol is not compatible with earlier versions,
211 nor are earlier versions compatible with this version. Because the
212 older protocol has huge security flaws, we feel that not
213 implementing backwards compatibility is justified.
215 * Some data about the protocol:
217 * It uses public/private RSA keys for authentication (this is the
218 actual fix for the security hole).
220 * All cryptographic functions have been taken out of tinc, instead
221 it uses the OpenSSL library functions.
223 * Offers support for multiple subnets per tinc daemon.
225 * New is also the support for the universal tun/tap device. This
226 means better portability to FreeBSD and Solaris.
228 * tinc is tested to compile on Solaris, Linux x86, Linux alpha.
230 * tinc now uses the OpenSSL library for cryptographic operations.
231 More information on getting and installing OpenSSL is in the manual.
232 This also means that the GMP library is no longer required.
234 * Further, thanks to Enrique Zanardi, we have Spanish messages; Matias
235 Carrasco provided us with a Spanish translation of the manual.
238 What still needs to be done before 1.0:
240 * Documentation. Especially since the protocol has changed, and a lot
241 of configuration directives have been added.
246 version 1.0pre2 May 31 2000
248 * This version has been internationalized; and a Dutch translation has
251 * Two configuration variables have been added:
252 * VpnMask - the IP network mask for the entire VPN, not just our
253 subnet (as given by MyVirtualIP). The Redhat and Debian packages
254 use this variable in their system startup scripts, but it is
256 * Hostnames - if set to `yes', look up the names of IP addresses
257 trying to connect to us. Default set to `no', to prevent lockups
260 * The system startup scripts for Debian and Redhat use
261 /etc/tinc/nets.boot to find out which networks need to be started
264 * Fixes to prevent denial of service attacks by sending random data
265 after connecting (and even when the connection has been established),
266 either random garbage or just nonsensical protocol fields.
268 * tinc will retry to connect upon startup, does not quit if it doesn't
271 * Hosts that are disconnected implicitly if we lose a connection get
272 deleted from the internal list, to prevent hogging eachother with
273 add and delete requests when the connection is restored.
276 What still needs to be done before 1.0:
279 * Failover ConnectTo lines, try another one if the first doesn't work.
