Port Check For Macbook Pro

Sometimes, there's a program running on a port and you don't know what it is. How do you find out? I find this happens when I start a webserver up to test something locally and then I forget about it. So, if I wanted to find out what was running on port 80: This command shows a list of open files. The -i option checks for internet addresses with the colon symbol representing a port (instead of an actual IP address). Note, I've only used this on Mac OS X. I'm not sure if there's an equivalent for *nix or if it's available in some package.

Check Port Mac Terminal

• A - show all ports, including those used by servers-n - show numbers, don't look up names. This makes the command a lot faster-v - verbose output, to get the process IDs-w - search words. Otherwise the command will return info for ports 8000 and 8001, not just '80' LISTEN - give info only for ports in LISTEN mode, i.e.
• Proceeding from Example of the address table, press S (for S earch), to display the following prompt. Enter MAC address: Enter the MAC address you want to locate and press Enter. The address and port number are highlighted if found (Example of menu indicating located MAC address.)If the switch does not find the MAC address on the currently selected VLAN, it leaves the MAC address.
