Bind

[Mad Unix]

Hi linuxers

I am setting up a DNS/BIND for my local office 100 users for resolving
internal (nonroutable) and external names (internet)
for internet usage it works fine but for internal one it shows problems
am not using real name i called only my.lan
my DNS server 10.5.1.30  hostname: linux1.my.lan
my clients having 10.6.x.0/24
my servers having 10.5.0.0/16

can any one tell me what am doing wrong?

root at linuxvmware:~# cat /etc/resolv.conf
nameserver 10.5.1.30
domain my.lan
search my.lan






root at linuxvmware:~# nslookup redhat.com
Server:         10.5.1.30
Address:        10.5.1.30#53
