Instead of configuring tunnels, you give tinc the location and +public key of a few nodes in the VPN. After making the initial connections to +those nodes, tinc will learn about all other nodes on the VPN, and will make +connections automatically. When direct connections are not possible, data will +be forwarded by intermediate nodes. + +By default, nodes authenticate each other using 2048 bit RSA (or 521 bit +ECDSA*) keys. Traffic is encrypted using Blowfish in CBC mode (or AES-256 in +CTR mode*), authenticated using HMAC-SHA1 (or HMAC-SHA-256*), and is protected +against replay attacks. + +*) When using the ExperimentalProtocol option. + +Tinc fully supports IPv6. + +Tinc can operate in several routing modes. In the default mode, "router", every +node is associated with one or more IPv4 and/or IPv6 Subnets. The other two +modes, "switch" and "hub", let the tinc daemons work together to form a virtual +Ethernet network switch or hub. Normally, when started tinc will detach and run in the background. In a native Windows environment this means tinc will intall itself as a service, which will restart after reboots. To prevent tinc from detaching or running as a service, use the -D option. +The status of the VPN can be queried using the "tincctl" tool, which connects +to a running tinc daemon via a control connection. The same tool also makes it +easy to start and stop tinc, and to change its configuration. diff --git a/configure.in b/configure.in index 5f1902bf..57815376 100644 --- a/configure.in +++ b/configure.in @@ -4,7 +4,7 @@ AC_PREREQ(2.61) AC_INIT AC_CONFIG_SRCDIR([src/tincd.c]) AC_GNU_SOURCE -AM_INIT_AUTOMAKE(tinc, 1.1pre2) +AM_INIT_AUTOMAKE(tinc, 1.1pre3) AC_CONFIG_HEADERS([config.h]) AM_MAINTAINER_MODE
