Unable to successfully use DNS on the Director Appliance
The Director appliance was just upgraded to SGME 184.108.40.206 but we can no longer connect to the device using a hostname in the address bar of the browser.
Can no longer connect to the ProxySG appliances from Director using their DNS name.
When attempting to connect to the Director interface using a DNS suffix (not just hostname) we receive the following error: "Unable to establish connection to Director. Hostname resolution may not have been enabled in the Director"
Attempting to do a traceroute to the same hostname from the Director appliance resulted in a gethostbyname: Host name lookup failure
The ifconfig output looks normal.
interface ether-0 ip address <director_IP>
1: To ensure the daemon - djbdbs- is running, execute this command in the shell. For details on how to acess the shell, see KB4178.
If it is not running, reload it by restarting Director, or running this command.
2: One known root cause Root cause of this symtom is this: The "djbdns" binary module needs the user "dnscache" to work properly. In this fault condition we are being forced to run as the root user because "dnscache" and "dnslog" users are missing.
NOTE: To follow the below steps you'll need to be proficient in LINUX command line syntax and also be able to navigate the VI text editor in LINUX. For more information on the VI text editor, see this WIKI site.
