...onnect = yes, tinc tries to establish connections to known hosts.

In a "decentrally managed vpn" it is very likely that host config files for some reachable nodes do not exist. Currently, tinc fills the logs with "Cannot open config file" messages. This commit changes the log level to LOG_DEBUG so syslog doesn't get filled by default. --- src/conf.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/conf.c

I know i'm new to the list but i'd like to propose something for tincd daemon. I'd like to mark all sockets established by a tincd process with a mark passed as an argument in the command line. What could be the purpose of this new option? The goal of this option is to be able to have several tincd process running at the same time using the same port but using different ip. In

I think it is relatively easy to do. There are two places in src/net_socket.c where you would have to call setsockopt() with the SO_MARK option: configure_tcp() and setup_vpn_in_socket(). The first one is run for all incoming and outgoing TCP sockets, the second one sets up the UDP sockets. Try it out and see if it really allows you to do the mark-based routing you want....
