[ros-general] Networking problem

[Jacques Mony]

Hi,

 I have trouble with ReactOS networking. Here is what I've tried so far:

First, I have made most of the tests under qemu 0.7.2 running on
Windows 2000 (I have the same results on Linux and Windows XP... using
same version of qemu).

I use the option "-user-net".

In ReactOS, I configured my network as follow:

  Gateway: 10.0.2.2
  IP Address: 10.0.2.15
  Netmask: 255.255.255.0

  I did also give a value to the nameserver, but it doesn't matter for
the problem I have.

- I can ping 10.0.2.2 from ReactOS (I assume this tells me the
userland tcp/ip stack of qemu works properly, as well as ReactOS
settings).

On the host, I have a webserver (IIS) and an FTP server running, as
well as SSH.

>  From ReactOS: 
- If I type "telnet 10.0.2.2 80 " and then enter some HTTP request
(GET / HTTP/1.0), I will only get an amount (1 to many) of blank
lines. In other words: no content.

- If I type "ftp 10.0.2.2 ", the ftp client seems to send a username
by itself ("6-w" !?). So my FTP tests stop here.

- If I type "telnet 10.0.2.2 22", I will get the SSH version message,
and when I type something, I get a "protocol mismatch" error, which
looks normal.

- If I type "wget 10.0.2.2", it seems to connect (the webserver gets
the query), but then it will say it received empty data and will loop
doing this forever.

- I also tried lynx. Lynx gave me the most interesting results. I was
able to connect to the server, ask me for a cookie, receive some
headers and finally, since my password wasn't good, it gave me the IIS
permission denied page. HOWEVER, there were a lot of error messages
during the process.

   Here is the one that appeared the most often: "Alert!: Unexpected
read error"
        There were also a lot of "Alert!: Invalid header "....""

What I seem to understand is that some data is lost from the packets.
Something like final characters. I never had this kind of trouble with
other OS running under qemu, so I guess the problem is in ReactOS
TCP/IP stack. But I also seem to be the only one to have this kind of
problem.

Any idea where I should look first?

I'm pretty new to ReactOS and windows programming, but I'll do what I
can to provide more detail or... fix this.

Thanks.
