"Need help to configure DNS on the Embedded system"

[nreddy]

Hi All,

 I am working on implementing wget future on my Embedded device.
 So i downloaded free wget sources (version 1.10.2) and compiled for my
system.
My system is walnut based one(IBM405EP processor). But wget is working if
i specify IP when i try to download some file from my support site(i gave
IP of support site), but when i specify like www.support.netenrich.com, it
is not able to resolve.

 I Modified /etc/resolve.conf, but still it says unable to resolve .

 I am using MontaVista Linux Kernel 2.4.20.

can some one let me know how to configure the DNS on any embedded systems.
I have gone through some of the meterial available on the net, but could
not resolve it.

Thanks in Advance,
Nagi Reddy.C

Which C library do you use?
Did you setup /etc/hosts.conf correctly?
It should look like this:
---
   order hosts, bind
   multi on
---

If you use glibc you shold add 'dns' to /etc/nsswitch.conf file like that:
---
   ...
   hosts: files dns
   networks: files dns
   ...
---
This will tell glibc to look for hostnames in /etc/hosts and via dns.
Additionally glibc needs the two libraries libresolv and libnss_dns for
this setting to work!

Good luck
Eberhard

I guess you meant to write: "/etc/host.conf", right?
