Re: Tunneling

[Joao Pedro Almeida Pereira <joao.almeida@xxxxxxxxxxx>]

Hello,
So basically i need to do
rc = channel_open_forward(forwarding_channel,
"HostB", 22,
"localhost", 5555);
sock = create_socket("localhost",5555)
con_sock = wait_for_client( sock )
while true:
if have_things_to_read( con_sock ):

size_data = read_from_socket( con_sock, data_from_socket )

channel_write(forwarding_channel, data_from_socket, size_data )

else if have_things_to_read( forwarding_channel):

size_data = channel_read( forwarding_channel, data_from_server)

size_data = write_to_socket( con_sock, data_from_server )
else:
sleep(0.1)
Something similar to this with all the control logic in order to handle the
case of errors.

?
