17. Using Windows and Winsock

This is the Windows Net Howto by Frisoni Gloriano <gfrisoni@hi-net.it> on 15 may 1997

This document tries to describe how to run the Windows trumpet winsock over the dosemu built-in packet driver, and then run all TCP/IP winsock-based application (netscape, eudora, mirc, free agent .....) in windows environment.

This is a very long step-by-step list of operation, but you can make little scripts to do all very quickly ;-)

In this example, I use the dosnet based packet driver. It is very powerful because you can run a "Virtual net" between your dos-windows session and the linux, and run tcp/application application without a real (hardware) net.

17.1 LIST OF REQUIRED SOFTWARE

• The WINPKT.COM virtual packet driver, version 11.2 I have found this little tsr in the Crynwr packet driver distribution file PKTD11.ZIP
• The Trumpet Winsock 2.0 revision B winsock driver for windows.

17.2 STEP BY STEP OPERATION (LINUX SIDE)

• Enable "dosnet" based dosemu packet driver:

        cd ./src/dosext/net/net
        select_packet      (Ask  single or multi ->  m)
  

• Make the dosnet linux module:

        cd ./src/dosext/net/v-net
        make
  

• Make the new dosemu, with right packet driver support built-in:

        make
        make install
  

• Now you must load the dosnet module:

        insmod ./src/dosext/net/v-net/dosnet.o
  

• Some linux-side network setup (activate device, routing). This stuff depends from your environment, so I write an example setup.

  Here you configure a network interface dsn0 (the dosnet interface) with the ip address 144.16.112.1 and add a route to this interface.

  This is a good example to make a "virtul network" from your dos/windows environment and the linux environment.

        ifconfig dsn0 144.16.112.1 broadcast 144.16.112.255 netmask 255.255.255.0
        route add -net 144.16.112.0 dsn0
  

17.3 STEP BY STEP OPERATION (DOS SIDE)

I suppose you know how to run windows in dosemu. You can read the Running Windows document if you need more information. Windows is not very stable, but works.

• start dosemu.
• copy the winpkt.com driver and the trumpet winsock driver in some dos directory.
• start the winpkt TSR. (dosemu assign the 0x60 interrupt vector to the built-in packet driver)

          winpkt 0x60
  

• edit the trumpet winsock setup file trumpwsk.ini. Here is an example of how to setup this file: (I think you can use less parameters, if you have the time to play with this file. You can also setup this stuff from the winsock setup dialog-box).

          [Trumpet Winsock]
          netmask=255.255.255.0  <-- class C netmask.
          gateway=144.16.112.1   <-- address in the default gateway.
          dns=www.xxx.yyy.zzz    <-- You must use right value for the dns.
          domain=hi-net.it
          ip=144.16.112.10       <-- Windows address in the dosnet.
          vector=60              <-- packet driver interrupt vector.
          mtu=1500
          rwin=4096
          mss=1460
          rtomax=60
          ip-buffers=32
          slip-enabled=0         <--- disable slip
          slip-port=2
          slip-baudrate=57600
          slip-handshake=1
          slip-compressed=0
          dial-option=1
          online-check=0
          inactivity-timeout=5
          slip-timeout=0
          slip-redial=0
          dial-parity=0
          font=Courier,9
          registration-name=""
          registration-password=""
          use-socks=0
          socks-host=0.0.0.0
          socks-port=1080
          socks-id=
          socks-local1=0.0.0.0 0.0.0.0
          socks-local2=0.0.0.0 0.0.0.0
          socks-local3=0.0.0.0 0.0.0.0
          socks-local4=0.0.0.0 0.0.0.0
          ppp-enabled=0            <-------- disable ppp
          ppp-usepap=0
          ppp-username=""
          ppp-password=""
          win-posn=42 220 867 686 -1 -1 -4 -4 1
          trace-options=16392
          
          [default vars]
  

• Now you can run windows, startup trumpet winsock and ..... enjoy with your windoze tcp/ip :-)
