.NET Code to find the IP of the Virtual PC at runtime

Hi,

Can one use the .net namespace System.net to find the Ip of the Virtual PC
running windows server 2003 on host xp pro.

The code I am running for a custom web part fails at runtime . I have tried
both Shared (NAT) and "host Ethernet card" option of network adapter.

Thanks

Yes, but you're in the wrong newsgroup. The fact that you're trying to find
the IP address of a virtual machine instead of a physical machine is
completely irrelevant...

Please post your question in microsoft.public.dotnet.languages.csharp, and
remember to include the code that you're trying to use, otherwise no-one
will be able to help you fix it...

If your .NET code is running inside the Virtual PC, any .NET function to =

detect the "computers" own IP address should return the IP address(es)=20
(if any) used by the Virtual PC.

If your .NET code is running outside the Virtual PC, the only ways I can =

think of to detect the IP address of the Virtual PC are:

a) Talk to a software interface exposed by the Virtual PC software=20
itself for this purpose.
b) Use network techniques to discover the IP address of the "remote"
computer which is the Virtual PC, for instance you could look up the IP=20
address for its computer name.
c) Use a software interface exposed by the Virtual PC software itself =

to determine the MAC address of the simulated network adapter in the=20
Virtual PC, then use the arp command (or its .NET API equivalent) to=20
determine the IP address associated with that "remote" network card.
d) Run a command or program inside the Virtual PC which communicates
its IP address to your .NET code outside the Virtual PC. This could be
as simple as sending a single UDP packet (containing some magic value)
to a port on the Host PC where your .NET code is listening for incoming=20
packets, comparing the contents with the magic value and checking the IP
return address of the packet if ok.
e) Use Virtual PC folder sharing to give the Virtual PC write access
to a folder on the Host PC, then inside the Virtual PC run a command=20
which reports its IP address to a file in the shared folder. (This is
really a crude variation of method d).

For each of these methods make sure to protect yourself from all the=20
ways in which malicious code in another Virtual or real PC could try to=20
provide you with the wrong address!
