Hi
i have to develop virtual ethernet adapter driver. but i do not know how to start?
WINDDK has some example?

“Virtual” means that you will not actually have an Ethernet adapter.
So, what WILL you be talking to? Where will the packets come from and
go to?

basically we are building a VPN client so for that i need a virtual Ethernet adapter driver.
For starters carefully examine, build and debug the Passthru and MUX samples
from the WDK. Neither of these is exactly what you want, but both
illustrate NDIS fundamentals that you must know thoroughly in order to
develop your driver.
Good luck,
Thomas F. Divine

Does your boss/customer read this list?
WINDDK has some example?
VNETMINI
NDISWDM
Did you bother to look?
From the “Network Samples” section of the WDK documentation:
The NDIS Virtual Miniport Driver sample illustrates the functionality of a
deserialized NDIS miniport driver without requiring a physical network
adapter.
Because the driver does not interact with any hardware, it makes it very
easy to understand the miniport interface and the usage of various NDIS
functions without the clutter of hardware-specific code that is normally
found in a fully functional driver. The driver can be installed either
manually using the Add Hardware wizard as a root enumerated virtual miniport
driver or on a virtual bus (like toaster bus).
Note This sample provides an example of minimal driver intended for
education purposes. The driver and its sample test programs are not intended
for use in a production environment.
The driver can be built in the Microsoft Windows XP, Windows Server 2003,
and Windows Vista WDK build environments.
The driver can be installed in the Windows XP, Windows Server 2003, and
Windows Vista operating system.

I am trying to develop virtual Ethernet adapter miniport. My dilemma is how
to make it “talk” to outside world through existing physical Ethernet
adapter, or I should say miniport, in the similar fashion as VMWare /
Virtual PC does.
What I am looking is direction on where to look for a solution. (ideas,hints)
Thanks in advance
Did you read the responses, they gave you all the direction you should need.
If you still can’t do this, I suggest a new field of work.

Information from ESET NOD32 Antivirus, version of virus signature database 4434 (20090917)
The message was checked by ESET NOD32 Antivirus.

ya don i am done what they said. but the main concern is that in my VPN client software user is supposed to connect VPN through DSL and how my virtual Ethernet adapter driver would fetch this packet from internet traffic (from which layer of network.) ? i searched on internet but no luck.

What you’re speaking about is doable, for instance, using MUX IM driver, which is “virtual Ethernet over another Ethernet”.

ya “virtual Ethernet over another Ethernet” like sonic wall vpn client ,citrix vpn client,cisco client etc.
None of these clients are “Virtual Ethernet over Ethernet” or MUX-IM
drivers. They are all “Virtual Ethernet” exposing IPv4 over TCP/IP of some
sort of secure encapsulation like IPSec.
PPPoE is an example of a ‘VPN’ over Ethernet directly. PPPoE is implemented
as an IM driver. The others are not.
What sort of encapsulation do you plan to use for this VPN?
Heaven knows we need another one since PPP+L2F, PPP+L2TP, PPP+PPTP PPP+HTTP,
GRE, UDP/ESP, IP+IP, IP+TLS, and who all knows or cares anymore.
But if you are just going to be doing what everyone else does, that is going
to look an awful lot like NDISWDM (root enumerated) talking to TDI or WSK
instead of talking to NDISPROT. Of course then you can come back and ask
how to write a TDI client or how to direct all of your packets into
user-mode or whatever.
Good Luck,
Dave Cattley

PPPoE is a WAN miniport upper edge and NDIS protocol lower egde.

Yes exactly. I kind of IM driver. Nobody ever said that the edges
themselves had to be of the same type. If one does this with an NDISWAN
Miniport upper edge and follows the rules precisely (serialized miniport)
you get to have fun with NdisIMSwitchToMiniport() etc. If you care to go
figure out how to do a newer 5.x CoNDIS miniport, well, you can live in the
de-serialized world still.
All fun stuff.
Cheers,
Dave Cattley

Looks like market for writing soft NDIS driver is much larger than the NIC one.

If only …
I assume ‘market’ here means that there is some remuneration involved

If you don’t get paid for it, why bother? You could just sit back with the
adult beverage of your choice and party on doing whatever you like. Some
may like doing drivers, but it is a completely different ballpark with
self-motivation being the only driver (pun intended - ;).

LOL
mm
I have on [very rare] occasion worked for “adult beverages” *as*
remuneration (although I generally expect pizza too).
