Note:
1, static IP and hostname resolution (reverse lookup) is important.
2 192.168.100.9 rtgps should be the first line in the /etc/hosts
3. Make sure that /etc/nsswitch.conf has “files” first for the hosts map
4. selinux disabled and system rebooted
5. firewall disabled ( or allow ports 15001 - 15009 and 17001 )

Please share the output of the below commands:
