search for: want_keepalive

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

Hello! I'm hoping that Gmail won't HTML format this mail so that I'll get flamed :) Anyway, my question relates to ssh_config. The problem I find is that the Host pattern is only applied to the argument given on the command line, as outlined in the man page: "The host is the hostname argument given on the command line (i.e. the name is not converted to a canonicalized host name
