[Spice-devel] spice proxy fail

[mzawdx wang]

Hi all:
    I met something strange when used netcat for proxy spice like this:

I run the command on the proxy server(192.168.3.128):

mkfifo backpipe
nc -l 12345 0<backpipe | nc 192.168.3.30 6188 1>backpipe

however, when I used spicy command to connect the vm on host(192.168.3.30):

spicy -h 192.168.3.128 -p 12345

the console stuck, and the spicy window can not be opened.


I have debug the spicy, found some clues：

1741     if (SPICE_IS_DISPLAY_CHANNEL(channel)) {
1742         if (id >= SPICE_N_ELEMENTS(conn->wins))
1743             return;
1744         if (conn->wins[id] != NULL)
1745             return;
1746         SPICE_DEBUG("new display channel (#%d)", id);
1747         g_signal_connect(channel, "notify::monitors",
1748                          G_CALLBACK(display_monitors), conn);
1749         spice_channel_connect(channel);
1750     }


the callback function: display_monitors was not called.

By the way, meanwhile I test the ssh tunnel proxy too, and it sounds like
good.
