That probably means one of the following:
- port 53 is being filtered on the ftp host
- port 53 is being filtered on the 192.168.1.4 host
- there is no name server running on 192.168.1.4
Try this and see if name service begins working.
/etc/rc.d/init.d/iptables stop
If that fixes things, then you need to visit your iptables config and allow DNS queries in/out.
Hope that helps.
Hi Chris:
Unfortunately, I have already stopped the firewall and DNS is running on 192.168.1.4. I took 192.168.1.4 out of the equation and used all the DNS servers that I have access to.... same result.
[root@ftp ~]# iptables -L -v -n Chain INPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination
Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination [root@ftp ~]#
