Mam Ubuntu 12.04 i nie jestem w stanie pozwolić na określony port w mojej zaporze ogniowej. Więc w zasadzie powiedziałem, że pozwolę na wszystko, ale wciąż nie działa. Proszę pomóż. nmap na tej maszynie z innej maszyny mówi:
$ nmap host_name
Not shown: 996 closed ports
PORT STATE SERVICE
22/tcp open ssh
80/tcp open http
139/tcp open netbios-ssn
445/tcp open microsoft-ds
a oto nmap z tej samej maszyny
$ nmap localhost
Starting Nmap 5.21 ( http://nmap.org ) at 2014-01-21 11:14 PST
Nmap scan report for localhost (127.0.0.1)
Host is up (0.000080s latency).
Not shown: 991 closed ports
PORT STATE SERVICE
22/tcp open ssh
25/tcp open smtp
53/tcp open domain
80/tcp open http
139/tcp open netbios-ssn
445/tcp open microsoft-ds
631/tcp open ipp
3306/tcp open mysql
8000/tcp open http-alt
Nmap done: 1 IP address (1 host up) scanned in 0.04 seconds
Chcę otworzyć port 8000 i oto wyjście z iptables.
