</I></H2>
13 I've discovered a way to run WfW's TCP/IP-
32 over a SLIP packet driver. This
14 allows WfW users to do Windows networking over dialup lines just like it is
15 possible with NT and the Windows
95 beta!
17 For instance, you can mount Microsoft's FTP server as a network drive in File
18 Manager or connect to an MS Mail post office over the Internet. Of course,
19 the usual Internet stuff works as well. Another interesting site is
20 WINSERVE
.001; check out www.winserve.com.
22 This method should work with any class
1 (Ethernet II) packet driver. However,
23 I'm not in a position to try anything else than SLIPPER/CSLIPPER.
25 <H3>Files you need:
</H3>
26 <B>WFWT32.EXE:
</B> ftp://ftp.microsoft.com/bussys/msclient/wfw/wfwt32.exe
28 Microsoft's free TCP/IP for WfW. It's a self-extracting archive which
29 should be executed in an empty directory.
31 <B>SLIPPER.EXE:
</B> ftp://biocserver.bioc.cwru.edu/pub/dos/slipper/slippr15.zip
33 Peter Tattam's SLIP packet driver. CSLIPPER.EXE is a variant which supports
34 VJ header compression.
36 <B>PDETHER.EXE:
</B> ftp://sjf-lwp.idz.sjf.novell.com/odi/pdether/pde105.zip
38 Don Provan's ODI-over-Packet Driver shim. This *must* be version
1.05 (or
43 Novell's LAN Support Layer. If you're an owner of Windows
3.10, you'll
44 have it on one of your install disks. Use
"expand a:lsl.co_ lsl.com" to
45 expand it. Microsoft has stopped bundling LSL.COM with WfW
3.11, though.
46 The newest version of LSL.COM can be downloaded as part of
47 ftp://ftp.novell.com/pub/netware/nwos/dosclnt12/vlms/vlmup2.exe.
48 However, it's not clear if this one may be legally used outside Netware
53 A configuration file for LSL and PDETHER. It should contain the following
62 Protocol IP
800 Ethernet_II
63 Protocol ARP
806 Ethernet_II
64 Protocol RARP
8035 Ethernet_II
69 A little hack of mine to disable the COM port used by the SLIP packet driver.
70 Usage is e.g.
"discomx 2" to disable COM2. This should be run before
71 starting WfW, otherwise you'll get
"device conflict" messages. Here it is:
74 F,=N)V8H.@`
"P(+^!`/.N3XH="=MT!DN`XP/
1XS')!R:)CP`$S2``
78 (Save this text to disk as
<I>filename
</I>, then run
"uudecode <I>filename</I>".
79 uudecode can be found, for instance, at
80 ftp://ftp.switch.ch/mirror/simtel/msdos/starter/uudecode.com )
84 An optional file which should be stored in your Windows subdirectory. It is
85 used to map NetBIOS computer names to IP addresses. Example:
88 198.105.232.1 ftp #PRE # ftp.microsoft.com
89 204.118.34.11 winserve
.001 #PRE # Winserve
92 <H3>How to install it:
</H3>
95 <LI>Put the files mentioned above into a directory, e.g. C:\SLIP.
97 <LI>Put the following lines into AUTOEXEC.BAT:
100 slipper com1 vec=
60 baud=
57600 ether (may vary with your modem setup)
103 discomx
1 (must correspond to SLIPPER's COM port)
105 (If you use another vec= setting, you must update that in NET.CFG as well.)
106 Use CSLIPPER instead of SLIPPER if your SLIP provider supports VJC.
110 <LI>Under Windows Setup, choose
"Change Network Settings".
111 <LI>Select
"Install Microsoft Windows Network".
112 <LI>In
"Drivers...", choose
"Add Adapter"
113 and install the
"IPXODI Support driver (Ethernet) [ODI/NDIS3]".
114 <LI>In
"Add Protocols...", select
"Unlisted or Updated Protocol". When asked for a
115 driver disk, enter the directory where you expanded WFWT32.EXE.
116 <LI>Configure TCP/IP (IP address, enable LMHOSTS lookup, try
204.118.34.11 as primary
117 WINS server). Remove all other protocols (NetBEUI, IPX/SPX).
120 <LI>Windows will probably update the first lines of AUTOEXEC.BAT with
124 c:\windows\odihlp.exe.
126 The
"odihlp" line must be moved behind the
"pdether" line.
128 <LI>Windows will also update NET.CFG with some
"Frame" lines. These must
129 be removed (except
"Frame Ethernet_II").
131 <LI>Somehow, you will have to dial in to your SLIP provider. I do it manually
132 before slipper (or cslipper) gets loaded, using a DOS-based terminal program.
133 But there are some automatic dialers around. I've seen recommendations for
134 ftp://mvmpc9.ciw.uni-karlsruhe.de/x-slip/slip_it.exe.
136 <LI>To connect to Microsoft's FTP server (or Winserve) go into File Manager,
137 choose
"Connect Network drive" and enter
"\\ftp" or
"\\winserve.001" into
141 <H3>How it works:
</H3>
143 Microsoft's TCP/IP-
32 requires an NDIS3 interface. NDIS is Microsoft's way
144 to interface with a network.
146 WfW also contains an NDIS3-over-ODI
"shim", whose real mode component is
147 ODIHLP.EXE. ODI is Novell's way to interface with a network.
149 SLIPPER is a Packet Driver (PD) for use over serial lines. PDs are everybody
150 else's way to interface with a network. SLIPPER's
"ether" option makes it
151 look like an Ethernet PD to applications using it.
153 A
"shim" is a program which simulates a network application programming
154 interface on top of another.
156 There is no NDIS SLIP driver which would work with WfW.
158 There is no NDIS-over-PD shim.
160 However, there's an ODI-over-PD shim (PDETHER) and an NDIS-over-ODI shim
163 OK, so let's do NDIS-over-ODI-over-PD!
165 This should have worked all the time; however, a non-feature in PDETHER
166 versions <
1.05 has prevented the method from functioning until now.
