nmap on Redhat?

[Carl Parrish]

Thanks Craig (and everyone) netstat is what I was looking for. nmap is 
*not* on this server. They were concerned that there was already 
activity on a port so I needed to see about that. I'm installing nmap 
now. btw iptables doesn't seem to be up and running. should it be on a 
RH 7.1? (I know it is on 7.2 and is *not* on 7.0). The plan is to leave 
them with something they can check when I'm done, and I don't think 
they'd be able to handle iptables from the command line (what is it 
about the command line that freaks newbies out?) Anyways I sort of 
remember using a gui front end for nmap a *long* time ago but don't 
remember which one. Does anyone have a suggestion for a easy to learn 
nmap frontend?
