nmap in RedHat 8
Can someone tell me how to start the preinstalled version of nmap tata comes with Redhat 8? If I go to a run command and type "nmap", the run box disappears and then nothing! I am on a learning curve with LINUX and would like to learn more. One reason I gained an interest in LINUX was to run nmap to check the security of my network. Redhat 8 won't let me manually install nmap (version/link http://download.insecure.org/nmap/dist/nmap-3.20-1.i386.rpm) because it says I have a newer vervsion installed. I was succesful at installing nmap on Redhat 7.2 but not on 8! Can someone please help me?
Thank You!!
