Installing OpManager Nexus on Linux

Prerequisites:

1. If OpManager Nexus is installed in Debian machines, make sure that the iputils-ping package is installed.
   
   This is required because OpManager Nexus uses the options of the Ping command provided by the iputils-ping package. Debian OS has two different packages, netkit-ping (installed by default) and iputils-ping. If iputils-ping package is not installed, OpManager Nexus will not be able to ping any of the managed devices and also itself and hence reports the status of all devices to be down.
2. Sometimes, you might encounter errors such as database connection not getting established or the server not starting up. To workaround these issues, comment the IPv6 related entries in the etc/hosts file.
3. Check if the DNS resolves properly to the IP Address on the system in which OpManager Nexus is installed. Add an entry to etc/host file with ipaddress and host name if there is trouble starting OpManager Nexus.
