Unable to Access Internet from the HP UX Server.

Dear All,

Please help me in this case...
Here I have 1 hp ux server and from that server I am not able to access Internet.

Already made all the entry in the /etc/resolv.conf file.

From nslokup and dig command, it is resolving the IP address of the Internet server name..like www.google.com, www.yahoo.com

But when I am trying to ping these servers, its not pinging and accessing from the Mozilla or Firefox and I am not able to access these sites...

I want to access only one site www.clickatell.com from the hpux server for sending SMS.

From all windows clients and all windows serves I can acces the interbet and all the sites...

Please help me...solve this problem!!!

Re: Unable to Access Internet from the HP UX Server.

"dig" command in hp-ux?

Do you have any proxy or firewall in your network?

Hope this helps!

No...Here we are not using proxy!

Re: Unable to Access Internet from the HP UX Server.

If you have double checked your gateway and netmask settings already, use "traceroute" and compare the results with a working system, e.g. "tracert" in windows client.

Hope this helps!

Re: Unable to Access Internet from the HP UX Server.

hi,

ask the network administrator if this machine is able to comunicate outside to the internet.

check the rooting ( default GW ) and /etc/reslov.conf ( /etc/nssswitch.conf )
