425 * Updated documentation; the documentation now reflects the
426 configuration as it is.
428 * Some internal changes to make tinc scale better for large
429 networks, such as using AVL trees instead of linked lists for the
432 * RSA keys can be stored in separate files if needed. See the
433 documentation for more information.
435 * Tinc has now been reported to run on Linux PowerPC and FreeBSD x86.
437 Version 1.0pre3 Oct 31 2000
439 * The protocol has been redesigned, and although some details are
440 still under discussion, this is secure. Care has been taken to
441 resist most, if not all, attacks.
443 * Unfortunately this protocol is not compatible with earlier versions,
444 nor are earlier versions compatible with this version. Because the
445 older protocol has huge security flaws, we feel that not
446 implementing backwards compatibility is justified.
448 * Some data about the protocol:
449 * It uses public/private RSA keys for authentication (this is the
450 actual fix for the security hole).
451 * All cryptographic functions have been taken out of tinc, instead
452 it uses the OpenSSL library functions.
453 * Offers support for multiple subnets per tinc daemon.
455 * New is also the support for the universal tun/tap device. This
456 means better portability to FreeBSD and Solaris.
458 * Tinc is tested to compile on Solaris, Linux x86, Linux alpha.
460 * Tinc now uses the OpenSSL library for cryptographic operations.
461 More information on getting and installing OpenSSL is in the manual.
462 This also means that the GMP library is no longer required.
464 * Further, thanks to Enrique Zanardi, we have Spanish messages; Matias
465 Carrasco provided us with a Spanish translation of the manual.
467 Version 1.0pre2 May 31 2000
469 * This version has been internationalized; and a Dutch translation has
472 * Two configuration variables have been added:
473 * VpnMask - the IP network mask for the entire VPN, not just our
474 subnet (as given by MyVirtualIP). The Redhat and Debian packages
475 use this variable in their system startup scripts, but it is
477 * Hostnames - if set to `yes', look up the names of IP addresses
478 trying to connect to us. Default set to `no', to prevent lockups
481 * The system startup scripts for Debian and Redhat use
482 /etc/tinc/nets.boot to find out which networks need to be started
485 * Fixes to prevent denial of service attacks by sending random data
486 after connecting (and even when the connection has been established),
487 either random garbage or just nonsensical protocol fields.
489 * Tinc will retry to connect upon startup, does not quit if it doesn't
492 * Hosts that are disconnected implicitly if we lose a connection get
493 deleted from the internal list, to prevent hogging eachother with
494 add and delete requests when the connection is restored.
