How to determine if two machines are connected on a 10mb/s or 100mb/s LAN?

[Apocalypse23]

Hi guys, i need to know how i would detedmine wether the 2 machines across a distance are connected on a 10mb/s or 100mb/s LAN just from their ip addresses. Do i do this from cmd prompt?

Any way to find out?

thanks

Are they on the same WAN? If there are any other machines or switches involved it may be hard to find out. Chances are it's 100mb if they're on a modern system.

as far as i know, from a remote command prompt this isnt possible. assuming you have credentials to the machines, the easiest way would be to simply remote desktop into them and check for yourself.

if you had absolutely no access to either computer, the only way i could think of would be to get the mac addresses from arp table, search the mac address table for the interface its connected to, and look at the negotiated interface speed. this is, of course, assuming you have higher end switches...

perhaps you should provide more details about why you need this information, network topology, computers, etc.

thanks for your input fellas, i spoke to my netoworking instructor and he said I would have to check or connect to each router at the network cloud to see what speeds i am getting, this way i would find any inconsistencies in the speeds and know what connections they are using, it sounds vague but i'm sure there is a lot more to it. And to answer the 1st replier's question, i'am not certain.

the speed of the border router at the cloud has nothing to do with the negotiated speed of lan clients.
