ClientView fails to start

Symptom:
ClientView does not start.

Open

Reason for the issue:
This error can occur when there are errors in the /etc/hosts file on the Dialogic Gate Control Element Management System (GCEMS) server.

Solution:
The GCEMS processes on the Linux server -  including ClientView and EventView - use the hostname defined in the /etc/hosts file. Other network services such as FTP, NTP, NFS, SSH, and Cacti can also be affected if this is not configured correctly.

The /etc/hosts file is created when the first network adapter is added to the system. It can be modified using either of the following methods:

Method 1 (Recommended): Use the network configuration GUI and select the HOSTS tab.


     Enter the IP address, Hostname, and Alias

Method 2 (for users with Linux experience): Manually edit the /etc/hosts and /etc/sysconfig/network files.

  The default /etc/hosts file will look like the following.

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost

Add the GCEMS server IP address to the /etc/hosts file.
     •  If running redundant GCEMS servers then add the IP address for both servers.
     •  Do not edit or remove the line for localhost 

Following is an example /etc/hosts file after your changes.

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost

192.168.0.100 PrimaryGCEMS

192.168.0.101 SecondaryGCEMS

If the /etc/hosts file is edited manually (not using the Linux network configuration GUI) then the hostname must also be added to the /etc/sysconfig/network file:
 

HOSTNAME=PrimaryGCEMS

More information
For more information about configuring hostnames in Linux, please consult the Linux documentation.

Verifying the configuration
You can use the following Linux commands on the GCEMS server to verify that the hostname is correctly configured:
 

uname –n

PrimaryGCEMS

hostname

PrimaryGCEMS
