RDP/telnet with a MAC address

Actually i know that we use IP address or hostname of the devices to connect remotley. So let's say i have a LAN

segment A with 200 PCs and mine PC1 at the far corner and i'm now at the 200th PC which is far away from my Pc. Let's say i forgot my PC name and as well as IP address now i can't go to my PC and check them but i've my MAC address.

So can i RDP/telnet or atleast speak to my PC with a mac address ?

Please don't mind if my question is worng.

Chandu

RDP/telnet with a MAC address

Hi,

Telnet and RDP both use IP so you need an IP address or name(which will be resolved to IP) to use these protocols.

Re: RDP/telnet with a MAC address

HI Chandu,

Alain is right, RDP and telnet uses IP address.

Just for information:

go to START->RUN and type CMD or COMMAND and hit ENTER) and the type "arp -a" and you will get a list of IP addresses and MAC Addresses.

ARP was not designed to translate addresses in the other direction, however. There is no universal mechanism to determine an IP address given a known MAC address, although it can be done in certain specific situations.

ARP maintains a list of both IP addresses and matching MAC addresses called the "ARP cache.

This is one way to derive an IP address from a MAC address; however, the mechanism is limited in many respects.

On Windows and some other operating systems, the "arp" command provides access to the local ARP cache. In Windows, for example, typing "arp -a" at the command (DOS) prompt will display all of the entries in that computer's ARP cache. Depending on how that local network is configured, however, this cache will often remain empty. At best, a client device's ARP cache only contains entries for other computers on the LAN.

Thanks for the info.

If you don't mind can you explain in which type of situtation it will done.

Hi,

RARP is a mechanism for getting IP address from RARP server( which has static MAC-IP mappings).
