how to get a hostname using a Ip address via pinging.
i mean how to ping a system using IP address in such a way that i can get hostname.

thanks for all reply.

This is so confuse.

You can't translate an ip address into a hostname using "ping". Ping wasn't intended to do so. I have no idea why you would want to use "ping" to do this, is there a reason?

If you just want to translate an ip into an hostname, try "host [your ip]" or "dig [your ip]", as example : " host 216.109.112.135 " . But this will only work if the hostname you are trying to get exist in a reverse zone on a DNS somewhere. as example, this will work on 216.109.112.135 (yahoo.com) but not on 216.239.57.99 (google.com). There isn't much you can do about it.

thanks a lot.

because i have lot of problem with DNS and domain name.

i can not setup my named for query.

[staff@Simlab-node3 staff]$ dig yahoo.com

; <<>> DiG 9.2.3 <<>> yahoo.com
;; global options: printcmd
;; connection timed out; no servers could be reached
[staff@Simlab-node3 staff]$


for my IP address.

[root@Simlab-node3 staff]# dig 10.255.240.119

; <<>> DiG 9.2.3 <<>> 10.255.240.119
;; global options: printcmd
;; connection timed out; no servers could be reached
[root@Simlab-node3 staff]#


[root@Simlab-node3 staff]# host 10.255.240.119
;; connection timed out; no servers could be reached
[root@Simlab-node3 staff]#

please help me..

Key is "no servers could be reached".
Is Simlab-node3 connected to the Internet (or an internet)? If yes, how? (I see you somehow reached linuxquestions.org on the Internet.)

It seems that you want to do a reverse lookup. Why?

The address you're trying to look up, 10.255.240.119, matches the pattern 10.x.x.x. I.e., it looks like a private address. Correct? So if anyone, the person who manages IP addresses internally at your organization should be able to give you the address of a DNS server, which could answer your query.

There seems to be a problem about your DNS configuration.

look at /etc/resolv.conf and make sure you have a valid DNS server ip in there. If not, edit one ( syntax is like : nameserver 192.168.0.1 )
