The SPCW client uses port 22 to communicate with the TPAM appliance. The service will not run if the port is being used by another program, such as SSHD.
Stop any programs using port 22 then start the service again.
Alternately, use a port other than 22 as the listening port.
For setup instructions please refer to the TPAM eSPCW Guide available
here.
