Re: Using ncat as a SSH proxycommand to connect trough proxy

[Nuno Gonçalves <nunojpg () gmail com>]

I believe I found the cause of the problem.

Machine at 192.168.137.3 have a tinyproxy running at port 8888
Machine at 192.168.137.5 have ncat listening at port 443 (sudo ncat -l 443)

I tested 3 commands from another machine:

nc -X connect -x 192.168.137.3:8888 192.168.137.5 443
ncat 192.168.137.5 443
ncat --proxy 192.168.137.3:8888 192.168.137.5 443


All BUT THE LAST, worked as expected.
With the last command, lines are only displayed at the remote
computer(192.168.137.5) in multiples of two. I.e, the first text line
is only displayed after the second is finished and return is pressed.

nuno@ground2:~$ nc -X connect -x 192.168.137.3:8888 192.168.137.5 443
