I am running RHEL 6.4

I want to find all active external ports.   For instance if I want to see if DB2 and WMQ are active I would want to know if anyone is listening on 50000 or 1414 (unless otherwise configured)

What Linux command can I use to see all active ports used externally

Thanks

You can use netstat or nmap. Netstat runs locally and tell you what ports are currently open; Nmap is a comprehensive network scan tool that allows you to probe open ports on the remote host

netstat -ant
yum install nmap
nmap --help
