OH, you say is right. IN other computer telnet my computer 53 port is connect failed. How can I do. thanks.
Then ping other ports, to see if ONLY port 53 or ALL ports are blocked.
i.e if you are running POP3 on your Linux server, you should:
telte 192.168.1.13 110
if you are running telnet or SSH you should:
telnet 192.168.1.13 23
telnet 192.168.1.13 22
Our purpose is to check which ports are open and which are dead. |
