I am using tow copies of gnet 2.0.4.tar.gz ; one copy is compiled under
linux, the other one is compiled under Win32-MinGW.
I don't know where to find the CVS (... and would like to :-)).
Gnet-src-2.0-20030531.zip are older, so I did not try them.

Here is a more complete report.

The linux box has address 192.168.1.3, the windows box 192.168.1.4.

#1 - Connecting linux-gconn-client to linux-"simple"-server, then typing
"Hello World" (to try echoing)

  linux-"simple"-server : 

    [lw poseidon examples]# ./echoserver 5555     
    Normal echoserver running on 0.0.0.0:5555
    Accepted connection from 192.168.1.3:1794
    Hello world                                   
    Connection from 192.168.1.3:1794 closed

  linux-gconn-client : 

    [lw poseidon examples]# ./echoclient-gconn 192.168.1.3 5555
    Hello world
    Hello world


Everything behaves like expected.


#2 - Connecting win32-gconn-client to linux-"simple"-server (all things
being equal, except the operating system of the client, and the fact that
the client and the server run on two boxes having different IP addresses)

  linux-"simple"-server :

    [lw poseidon examples]# ./echoserver 5555
    Normal echoserver running on 0.0.0.0:5555
    Accepted connection from 192.168.1.4:1392

  win32-gconn-client : 

    lw HERMES /g/lang/gnet-2.0.4/examples
    $ ./echoclient-gconn.exe 192.168.1.3 5555
    Connection timeout

The server detects the establishment of a connection, but after 30 seconds,
the client reaches the timeout.

Yes I am aware of it. During its execution, the client is notified of a
timeout event.

I am using Tor's glib 2.2.3 binaries.

Maybe an iochannel problem under Win32... But who knows... It's hard to
figure out for me, as I am not used to the io part of Glib.
