whois server problem.
 

bash-2.05$ whois www.google.com

Then how can i query the server for information of google.
Where the error stands?Thanks.

works fine for me. It looks like you might have a problem resolving internic.net (have you tried 'ping internic.net')? Trying 'whois -h $(host internic.net) google.com' might work - I get 198.41.0.6 as 'host internic.net', and looking at your address it seems you've picked up the hostname for www.internic.net, which apparently doesn't have port 43 listening for whois queries.

If I 'host whois.internic.net' I get 198.41.0.6 too, so it seems you're trying to connect to the wrong IP address. That doesn't solve the error on the first line; it's some kind of DNS problem so I'm not going to get into that... :)

Hope this helps,
Andrzej

Edit: corrected port typo

bash-2.05$ whois -h 198.41.0.6 google.com
whois: connect: Connection refused
bash-2.05$

bash-2.05$ ping -sa 198.41.0.6

Connection refused.which looks no internal problem here in my pc.But remotely.

--Whoops--

Just confirmed that it is. Looks to me like you might have a firewall blocking whois requests.

OK, hmm... The only thing I can think of is that somehow your 'whois' is trying to connect to another port instead of the default of 43. If I issueI get my whois lookup, so try explicitly specifying port 43 to see if that helps.

If not - then I can show that it's not a remote problem at internet.net, and if you can show it's not an internal problem then it must be something in the middle, like a firewall. But let's hope this works first...

Also, have you considered adding --verbose to your command line arguments to get more detail on what is going on?
