A lot of Mac users are asking: After upgrading to Bigsur, network utilities are no longer available. How does port scanning work? What are the commands for terminal replacement that come with MacOS? Anything else?
MacOS Big Sur 11 new system update tool
Answer:
The “Web utility” in Big Sur is deprecated.
However, you can still run Unix commands such as netstat, ping, lookup, and traceroute on the terminal to implement related functions.
To scan ports, run the nc command.
The following two commands are used to scan ports 21 and 1-1024 of 192.168.1.1 respectively
Nc – zv 192.168.1.1 21
Nc – zv 192.168.1.1. 1-1024
To obtain the usage manual of the NC command, run the following command on the TERMINAL or search for it
man nc
After upgrading to macOS Big Sur, there are no web utilities. I hope it was helpful. For more Mac issues, please check out future Software Park.
