Hi
A “martian source” is a joke / referral to a source “Out of this world”. This usually implies Mars, as Venus is uninhabital (too hot).
This means, it’s not possible to route something like that over the internet, so usually the source is something in house, but completly wrong or not configured properly (Like factory defaults)…
Hope that helps to understand the meaning of “Martian Source”.
- Can’t be from this world, so it must come from Mars (or a Martian)!
Another term often seen on firewalls and packet sniffers is “runt”. A term from farming, implying a piglet born too early or something like that. (I’m not a farmer). This means a misformed packet, usually due to a defective NIC or Cable (wiring).
My 2 cents
