I just finished the packet tracer activity, 'configure IOS intrusion prevention system using CLI'. Now I'd like to create a custom signature that detects a certain piece of malware's behaviour like its port scanning pattern, using a signature engine,...
I tried to run multiple commands simultaneously on Command Prompt of a PC on Packet Tracer using '&'.
ping 10.0.0.10 & ipconfig
This command works on Windows cmd but not on Packet Tracer cmd. I also tried ';' but it didn't work either.
The first six digits of a MAC address is an OUI. If one manufacturer makes more than 16,777,216 devices using the same OUI, some devices will have a duplicate MAC address.How do manufacturers avoid this problem? Do they buy a new OUI from IEEE?
