BIND (cannot ping hostnames, but can ping IPs)
I am running centOS 6.3 in a virtualized vmware environment.
Host: ESXI 5.1 Using: Vsphere Client Everything is bridged on my adapter for ESXI. I have installed BIND on my centOS svr. I have edited my iptables to configure port 53 through the firewall with both udp/tcp. I have edited named.conf and entered my IP and loopback in to "listen-on port 53" I have also done { localhost; InternalIP/26; }; in the allow-query section /etc/sysconfig/network-scripts/ifcfg-eth0 looks like this: DEVICEE="eth0" BOOTPROTO=none NM_CONTROLLED="no" ONBOOT="yes" TYPE="Ethernet" DOMAIN=localhost UUID="234" HWADDR=MAC NETMASK=MASK IPADDR=IP of internal PREFIX=26 GATEWAY=GATEWAY DOMAIN=localhost DNS1=127.0.0.1 PEERDNS=no /etc/resolv.conf looks like this: domain localhost nameserver 127.0.0.1 I have restarted everything, but I can't seem to figure out why I cannot dig (google.com) or ping google.com or any other host name for that. Please help!!!! |
What errors are you getting? Are you able to look up hosts on your local network? Does netstat show anything listening on port 53? More information would be really helpful - not just what you changed, but what the config looks like.

I got the issue worked out. NTP was not set up properly. I can resolve host names now but I am getting errors in the process when I ping a new host. I am thinking that ipv6 is my problem in this situation but I may be wrong. Here are the errors: Mar 29 17:23:31 pcrepair named[2075]: error (network unreachable) resolving 'yahoo.com/A/IN': 2001:503:231d::2:30#53 Mar 29 17:23:31 pcrepair named[2075]: error (network unreachable) resolving 'com/DNSKEY/IN': 2001:503:a83e::2:30#53 Mar 29 17:23:32 pcrepair named[2075]: error (network unreachable) resolving '45.36.190.206.in-addr.arpa/PTR/IN': 2001:503:ba3e::2:30#53 Mar 29 17:23:33 pcrepair named[2075]: error (network unreachable) resolving 'arpa/DNSKEY/IN': 2001:dc3::35#53 Mar 29 17:23:33 pcrepair named[2075]: error (network unreachable) resolving 'arpa/DNSKEY/IN': 2001:500:2f::f#53 Mar 29 17:23:33 pcrepair named[2075]: error (network unreachable) resolving 'in-addr.arpa/DNSKEY/IN': 2001:500:87::87#53 Mar 29 17:23:33 pcrepair named[2075]: error (network unreachable) resolving 'in-addr.arpa/DNSKEY/IN': 2001:43f8:110::10#53 Mar 29 17:23:33 pcrepair named[2075]: error (network unreachable) resolving 'in-addr.arpa/DNSKEY/IN': 2001:67c:e0::1#53 Mar 29 17:23:33 pcrepair named[2075]: error (network unreachable) resolving 'w.arin.net/A/IN': 2001:dc3::35#53 Mar 29 17:23:33 pcrepair named[2075]: error (network unreachable) resolving 'x.arin.net/AAAA/IN': 2001:dc3::35#53 Mar 29 17:23:33 pcrepair named[2075]: error (network unreachable) resolving 'z.arin.net/A/IN': 2001:dc3::35#53 Mar 29 17:23:33 pcrepair named[2075]: error (network unreachable) resolving '206.in-addr.arpa/DNSKEY/IN': 2001:500:98::63#53 Mar 29 17:23:33 pcrepair named[2075]: error (network unreachable) resolving '206.in-addr.arpa/DNSKEY/IN': 2001:500:31::63#53 Mar 29 17:23:33 pcrepair named[2075]: error (network unreachable) resolving '206.in-addr.arpa/DNSKEY/IN': 2001:500:14:6050:ad::1#53 Mar 29 17:23:34 pcrepair named[2075]: error (network unreachable) resolving '36.190.206.in-addr.arpa/DS/IN': 2001:5a0:10::2#53 Any ideas? |
