i gut suse 10.2 with latest nmap 4.50 (ISO date 2007-12-13). nmap
works.. but if i try to view only hosts with open ports (nmap --open -v
10.0.0.0/24 -p 5900) it does not show ONLY open ports, but shows ALL
scanned hosts with with CLOSED Ports too. thats not what i do expect if
the manual says "show only open ports using --open"
pls check yourself.
I cannot reproduce this. I tried:
$ sudo nmap -v --open -p75-85 192.168.1.0/24
I also tried with -d instead of -v, only using a known closed port (85)
for all hosts, and only scanning one host, but --open worked fine for
every combination of these. Maybe SuSe applies patches to packages, and
somehow that's what messed it up?
