how to change the dns entries on AIX Version 5.2?
hi experts,
I need to change dns entries on some linux, unix servers. How do I do that? so for example change dns 192.168.88.1 to 192.168.88.2? I have no experience with this OS , so please be specific.

For Debian based linux distros as well as AIX edit the file /etc/resolv.conf. You'll find the DNS setting there.
In Linux you'll need to restart your network afterwards: /etc/init.d/networking restart

Hi,
do you mean you changed the address of your DNS server and now you have to make this new nameserver address known to AIX?
If so - that's just easy:
Edit /etc/resolv.conf and change the address beneath "nameserver" according to your needs.
That's all. No need to recycle any daemon process, the resolver reads the contents of /etc/resolv.conf at any new request, and there is no dns cache (nscd) in AIX.

when I enter the command nameserver 192.168.88.39 and hit return I get nameserver: not an editor command. What am i doing wrong?
this is what I get after I enter the Edit /etc/resolv.conf command....
irvqavu03 # edit /etc/resolv.conf
"/etc/resolv.conf" 2 lines, 48 characters

OK.
1. backup /etc/resolv.conf (as root)
cp /etc/resolv.conf /etc/resolv.conf_backup
2.
echo "nameserver 192.168.88.2" > /etc/resolv.conf
cat /etc/resolv.conf_backup >> /etc/resolv.conf

wesly_chen,
this way frankbustos will end up with two "nameserver" entries in /etc/resolv.conf.
I don't think this is desired.

That's true. However, it uses the top one first, which is 192.168.88.2.
For better one,
echo "nameserver 192.168.88.2" > /etc/resolv.conf
grep -v "nameserver" /etc/resolv.conf_backup >> /etc/resolv.conf
Thanks for the advice.
