I'm trying to set TSM integration with TEC. I have added the following lines in 
the dsmserv.opt:
techost 9.9.9.1
tecport 1555
tecbegineventlogging yes
When I restart the TSM server I get the following error message:
ANR8214E Session open with 9.9.9.1 failed due to connection refusal.
ANR8683E Unable to connect to the Tivoli event server at 9.9.9.1 on port 1555.
ANR2822I  Event logging ended for the TIVOLI receiver.

Any suggestion?

Thanks in advance
Regards
