Я использую CentOS 5.3 в контейнере openVZ, и я получаю ошибки "операция не разрешена" из Nmap.
[root@test nmap-5.21]# ./nmap scanme.nmap.org

Warning: File ./nmap-services exists,
but Nmap is using
/usr/local/share/nmap/nmap-services
for security and consistency reasons.
set NMAPDIR=. to give priority to
files in your local directory (may
affect the other data files too).

Note: Host seems down. If it is really
up, but blocking our ping probes, try
-PN Nmap done: 1 IP address (0 hosts up) scanned in 3.15 seconds
У меня нет установленных правил iptables.
Как я могу заставить это работать?
