Dear PMM:-
My problem is be sure that the port number 53 is opening cause
When I try to access the internet I have the following :-
# ping 4.2.2.2
4.2.2.2 is alive
# ping
Yahoo!
Ping: unknown host ww.yahoo.com
So when I put the
Yahoo! at the browser it can’t be open
When I use this command
# dig
Yahoo!
I got the real IP for yahoo home page when and put it in the browser the browser the yahoo home page is open but when i try to open any link it can't be open
After I check with my ISP cause no body from his customer service can be support UNIX system one of them say to me please check port 53 if open to retrieve DNS service or not cause my problem in DNS
Your feedback is highly appreciated
