You notice the Symantec Endpoint Protection (SEP) Client is not connecting to the Endpoint Protection Manager (SEPM), as the green dot is missing from the Symantec shield icon in the system tray (or in the Clients tab in the SEPM console)
To test connectivity from a SEP client to the SEPM type the following URL in a web browser on the client:
A successful connection returns a web page that displays "OK."
Use the following command to perform a test, where SEPM_IP_OR_HOSTNAME is the IP address or hostname of the management server, and PORT is the appropriate port number.
# curl -l http(s)://SEPM_IP_OR_HOSTNAME:PORT/secars/secars.dll?hello,secars
Doing so will return the HTTP response code. 200 OK, if reachable. Alternatively, using wget on the above URL will download the response page.
If testing HTTP connection, the default port is 8014. If testing HTTPS, the default port is 443 and does not need to be explicitly given. If you have customized these ports in the SEPM configuration, then be sure to use the proper values here.
