To make sure SKFS is running as expected, we highly recommend to regularly monitor the server using the ping web service. Use the sample client application skfsclient.jar (installed as part of the SKFS installation) to call the ping web service.

NOTE: On the FIDO2 server, the client application can be found under the /usr/local/strongkey/skfsclient directory.

Different methods are listed here:

• Ping SKFS using REST and PASSWORD authorization:
  

  shell> java -jar skfsadminclient.jar P https://[FQDN]:8181 1 REST PASSWORD fidoadminuser Abcd1234!
  
  OUTPUT
  $ fidoserver:~/skfsclient> java -jar skfsadminclient.jar P https://`hostname`:8181 1 REST PASSWORD fidoadminuser Abcd1234!
