[SOLVED] How to configure DNS settings?

[sachin.parnami]

Hi All,

I am getting problem while setting up my DNS

sachin@sachin-laptop:/opt/deploy$ dig some.test

; <<>> DiG 9.5.0-P2 <<>> some.test
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 1782
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;some.test.                        IN        A

;; Query time: 2 msec
;; SERVER: 192.168.0.100#53(192.168.0.100)
;; WHEN: Thu Feb 19 12:33:15 2009
;; MSG SIZE  rcvd: 31

so can buddy please guide me how am i suppose to do the correct configuration?

DNS server is specified in /etc/resolv.conf, but this file gets overwritten if you're using NetworkManager (which uses DHCP) or DHCP directly for your network settings.

If you're using them, then your DNS server address will be specified by your DHCP server.

If you're using static IP address, then point your DNS setting at a valid name server using the the 'system-config-network' tool (or edit /etc/resolv.conf yourself).

Thanks for your reply

Actually i am using DHCP and i have made changes in resolve.cfg as well but even though i get no result

the file look like this

#file present in /etc
search some.test
domain some.test
nameserver 192.168.0.10

Any idea ?

Are you trying to run you own DNS server? If not then you have to edit your configs to use your ISP's DNS servers. If you are then what type of server are you trying to setup? Cache-Only or a full DNS server? If you are trying to setup your own DNS server I would suggest searching the web there is a lot of good information out there on how to setup a DNS server. Remember this is not a small task. A lot of reading is required to fully understand what you are doing. Start with the Redhat Documentation for setting up a DNS server.

If you are using DHCP, your DHCP servers should provide the Nameservers to use. Check your /etc/nsswitch.conf file to ensure you have "dns" or "files dns" for the "hosts" entry.
