Troubleshooting Basic Connectivity Issues

The Nymi Enterprise Edition (NEE) and Connected Worker Platform (CWP) solutions rely on bidirectional communications between components over TCP ports.  

Perform the following steps to troubleshoot connectivity issues between the NES server and other components in the solution, such as the enrollment terminal, user terminals or the centralized Nymi agent server.

1. Inspect firewall logs to confirm that bi-directional communication occurs between the client and server.  The components communicate over the following ports:

Component 1 Component 2 Default TCP Port
NES server User Terminals 80/443 (depending on configuration of NES)
User Terminal Nymi Agent server 9120
RDP/Citrix client Nymi Agent server 9120
NES Administrator Console machine NES server 80/443 (depending on configuration of NES)
     

2. On the component machine, from a command prompt type the following commands to confirm that the machine can communicate with the NES server (and that output returns the correct IP addresses and names):

ping <FQDN_NES_server>

ping <shortname_NES_server>

ping <ip_address_NES_server>

nslookup<FQDN_NES_server>

nslookup <shortname_NES_server>

nslookup <ip_address_NES_server>

3.  On the NES server from a command prompt type the following commands to confirm that the NES server can communicate with the client (and that output returns the correct IP addresses and names):

ping <FQDN_component_machine>

ping <shortname_component_machine>

ping <ip_address_component_machine>

nslookup <FQDN_component_machine>

nslookup <shortname_component_machine>

nslookup <ip_address_component_machine>
