Determine the IP Address of the Linux Server, check the field beside "inet addr:" beside eth0 running the below command:
- ifconfig
- Note, if you have multiple NICs, you will see multiple eth like eth0, eth1. Please consult your system administrator to determine the right IP in a multiple IP environment
Find the hostname running the below command:
- hostname
Backup and edit the /etc/hosts file with the IP Address and the hostname on the Linux Box as below:
- 127.0.0.1 localhost localhost.localdomain <IP Address> <hostname>
For example, if the IP Address is 10.0.0.0 and the host name is testbox1.testbox.com, the /etc/hosts file should look like:
127.0.0.1 localhost localhost.localdomain 10.0.0.0 testbox1
