Troubleshooting Cisco Configuration Engine Installation
Installation aborted with error message “Hostname value retrieval by system calls 'gethostbyaddr()' and command 'hostname' have different values returned. Please correct it also make sure 'ifconfig' is set in your PATH before installing Config Engine 3.5”
To resolve this problem, follow these steps:
Step 1 Make sure the hostnames configured in /etc/hosts, /etc/sysconfig/network and/or DNS server are consistent with what’s returned by “hostname –s” command.
Step 2 Make sure the ifconfig command is in the $PATH environment variable
