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

Hi! There are configuration knobs (TCPKeepAlive) to enable/disable the use of TCP keepalives both in the ssh client and server. Unfortunately some UNIX systems default to SO_KEEPALIVE=on and some to =off. This may even be settable on a per host basis (OpenBSD default net.inet.tcp.always_keepalive=1 ???). For the TCPKeepAlive configuration knob I would like to propose changes along the lines
