Estimate Ethernet cable distance by software possible?

Does anyone have any idea on measuring or estimating cable distance by software (meaning linux networking tools) ?

Some years ago I saw a smart cable tester with a TFT monitor which was able to do that, but not alone. You had to insert an RJ45 node on the other end. And then you should be able to view a reading in meters like "50m".

This might sound silly but I don't know how did it work, so I don't know If it's possible at all.
