Hi,

I am using redhat 7 via VM, the question is am able to ping the server using ip address and hostname within the server

[root@yogeshgowda ~]# ping 192.168.60.114
PING 192.168.60.114 (192.168.60.114) 56(84) bytes of data.
64 bytes from 192.168.60.114: icmp_seq=1 ttl=64 time=0.046 ms
64 bytes from 192.168.60.114: icmp_seq=2 ttl=64 time=0.045 ms

[root@yogeshgowda ~]# ping yogeshgowda
PING yogeshgowda (192.168.60.114) 56(84) bytes of data.
64 bytes from yogeshgowda (192.168.60.114): icmp_seq=1 ttl=64 time=0.043 ms
64 bytes from yogeshgowda (192.168.60.114): icmp_seq=2 ttl=64 time=0.046 ms

but if I use nslookup command am getting following error

[root@yogeshgowda ~]# nslookup yogeshgowda
;; connection timed out; trying next origin
;; connection timed out; no servers could be reached

and I am able to ping the ip address from windows but not with hostname

This has to do with your search strings. Look at the FQDN. The server knows it's shortname and FQDN but windows maybe doesn't.
Try nslookup with it's FQDN if that doesn't resolve then you don't have an entry in DNS for the server.

Thanks for the reply,

may i know what is FQDN.

I think the first thing you need to do is research DNS - what it is, what it’s for, how it works.

For instance, the /etc/hosts file is a common way to define host-names, and this is probably where the name of your host was stored.

Otherwise, your server attempts to use the "DNS" service to resolve the domain-name. (As it did to resolve the domain-name, "linuxquestions.org.")

FQDN = Fully-Qualified Domain Name.

I am quite certain that the domain-name you seek should have been defined in the hosts-file, and that if you now put it there, your problem will go away.

Hi yogi89 - Welcome to LQ.

FQDN is Fully Qualified Domain Name. Instead of just the short name "yogeshgowda", the FQDN would be "yogeshgowda.something.somethingelse", for example.

Good idea to read up on DNS as suggested above.

Cheers :-) !

Fully Qualified Domain Name i.e google.com.

How did you configure networking for the VM? If nslookup can not access any servers then your VM might have a host only network and can not access the internet.

However, unless you add the VM hostname to the Windows hosts file or have local DNS service running you will not be able to ping computers on the LAN by hostname.

I am new to the linux/unix env,,,,,, all I required is to ping my hostname (linux VM) from windows local server and "nslookup hostname" cmd to give the normal o/p, if it requires any snapshot from my side please let me know.

I have added my hostname and ip in /etc/hosts/ but still nslookup is not showing the desired o/p

I didn't configured anything fro VM, I have only changed the hostname and added that hostname in /etc/hosts/ after that i am able to ping the hostname

Hi again yogi89 ... There is a field in the /etc/hosts file for the FQDN, as well as one for the short name. Did you enter both ?

Hello rickkk,

thanks for ur patience to help out, here is what my /etc/hosts contains


[root@JKT ~]# more /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
192.168.60.114 yogeshgowda yogeshgowda.mydomain.com
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
[root@JKT ~]#

It does not look like your VM network is configured to access the internet or you don't have any name servers in your /etc/reslov.conf file.

What is the desired output? nslookup queries the Domain Name System. Your VM hostname is not a real registered FQDN and therefore your only going to see something similar to the output below.

What are you trying to accomplish?

There are several things the OP can do:

1. Check and ensure that his DNS server has an entry for his linux box. If one is not present he needs to add it.

2. If he cannot add a DNS entry then he is going to have to add an enter to the host file on the windows box so it know what IP Address to use.

3. Just use the IP address to connect/talk to the linux box.

The question is which host are you editing the host file on? Linux or Windows? This needs to be done on the windows machine.

Also you should be aware that if you use a host file nslookup is not going top work as nslookup uses a DNS server to resolve its queries for which you do not have an entry.
Ping on the other hand will give you the correct ip address as it does look at the host file before DNS.

Problem is am not able browse in VM, and mailx is not working I dont know whether mailx is properly configured or not, I need to enable some scripts in cron which sends the o/p to my mail.

This is what my /etc/resolv.conf cotains.
[root@JKT ~]# more /etc/resolv.conf
# Generated by NetworkManager
search jktech
nameserver 202.138.96.2
nameserver 8.8.8.8


I'm trying into install progress database into my VM, before that I need to be sure with all the perquisites in VM server.
