Hello Admins,

I am trying to ping from my solaris 10 command prompt... But it's saying unknown host..

I can ping and others... Internet is OK..

What might be the issue?

You don't ping a webpage, you ping an IP address or domain name. Get rid of the /xml/ns/j2ee

But I am able to ping the same site from another standalone workstation...I mean from my laptop workstation... (for verification)

Yes, ping is ICMP, echo and echo/reply, a child protocol of IP, not TCP (brother) or HTTP (nephew, child of TCP). Maybe the ping there ignores better.

That might be but why the solaris workstation which is running on my vmware is able to ping the same site .... ?

But only the server in my environment is not able to ...why so?

Try looking up the addresses with "nslookup". is not a valid address for this purpose.

Even does not respond to ping. does respond to ping.

I can only guess that you have some version of ping which simplifies the name (or an entry in /etc/hosts or local DNS which provides an IP address).

If you do need to ping an external server, keep it short! i.e. Use a parameter to ping to limit to say 2/3 packets. Please don't send continuous ping across the Internet.
