Thanks for looking at this. The other things you list look fine. I did notice
something else with the log, though. Below I type the line "hello". Then
there's the 80 second delay. And then there's the log messages after the
"hello":
debug1: Entering interactive session.
client> nc localhost 1110
hello
debug1: Connection to port 1110 forwarding to localhost port 1212 requested.
debug2: fd 6 setting TCP_NODELAY
debug2: fd 6 setting O_NONBLOCK
debug3: fd 6 is O_NONBLOCK
debug1: channel 2: new [direct-tcpip]
debug2: channel 2: open confirm rwindow 2097152 rmax 32768
I think the delay no longer happens, with subsequent lines, because
TCP_NODELAY and O_NONBLOCK get set. I wonder if there's a way to configure
things to set those from the start?
