6d2d3669f3 Make keepalive handling more robust, this should now match what OpenSSH does 2014-08-19 23:08:56 +08:00

da57dd13c5 Set tcp priority as follows: 
if (connecting || ptys || x11) tos = LOWDELAY;
else if (tcp_forwards) tos = 0;
else tos = BULK;

TCP forwards could be either lowdelay or bulk, hence the default priority.

2d4d9627a2 Rearrange the channel buffer sizes into three neat use-editable values in 
options.h. Increasing RECV_MAX_WINDOW gives big network performance
increases - even with the present buffers (which haven't changed) it
performs a lot better.
Next step is to make the window size a cmdline option.

cdbe853595 A hack to make dbclient to tcp forwarding netcat style. 
eg

./dbclient -i testkey -L 1234:remotehost:remoteport  tunnelhost

will ssh to tunnelhost (using testkey, there's no way to ask for a password)
and then tcpfwd to remotehost:remoteport on stdin/stdout.

There's no way to give a cmdline password, so -i for a keyfile will have to do.
Yet another reason for agent forwarding.

The 1234 is a dummy var, I think it has to be a valid portnumber though.
