Ubuntu 12.04'üm var ve güvenlik duvarımdaki belirli bağlantı noktalarına izin veremiyorum. Ben de temelde her şeye izin vereceğimi söyledim ama hala çalışmıyor. Lütfen yardım et. diğer makineden bu makinede nmap diyor ki:
$ 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
ve burada aynı makineden nmap var
$ nmap localhost
Starting Nmap 5.21 ( http://nmap.org ) at 2014-01-21 11:14 PST

Nmap done: 1 IP address (1 host up) scanned in 0.04 seconds
Bağlantı noktası 8000'i açmak istiyorum ve işte iptables'ın çıktısı.
