nmap new version can't run as root
I'm hoping that this is something simple that I'm overlooking.
I logged on as joe_user and downloaded and extracted version 3.75 to that user's home directory (within X). I opened a terminal and su'd to root, entered that directory and ran ./configure && make && make install. I didn't get any errors on install and thought everything was good...except;
When I run nmapfe (or nmap) as that user, I have version 3.75, but limited permissions - when I run the same as root, I'm still at v3.50 with full rights.
root owns /usr/bin/nmap and nmapfe:
Any ideas or suggestions would be most welcome.
