I really need some help to understand by name resolution is not working from a client machine.
$ nslookup
;; connection timed out; no servers could be reached
Here are some details:
1. Version of bind installed is 9.3 on EL5.
2. I can successfully perform nslookup, reverse lookup, dig, host commands on the DNS server itself.
3. I can ping from the client to the DNS
4. I can telnet (at port 53) successfully from client to DNS
5. No error messages in /var/log/messages
6. I have turned off Firewall between DNS and client (iptables off, ip6tables off, selinux disabled)
7. I have tried to strace the nslookup it appears that it is sending the lookup command to the right place.
sendmsg(20, {msg_name(16)={sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("")}, msg_iov(1)=[{"\263\221\1\0\0\1\0\0\0\0\0\0\3vm2\vhomenetwork\3com"..., 37}], msg_controllen=0, msg_flags=0}, 0 <unfinished ...>

Can someone please help me understand why this is not working?
