Here is for ftp port
~~~~~~~~~~~~~~~

./check_tcp -H localhost -p 60021
TCP OK - 0.003 second response time on port 60021
|time=0.002922s;0.000000;0.000000;0.000000;10.000000

./check_tcp -H localhost -p 60021 -S
CRITICAL - Cannot make  SSL connection 15556:error:140770FC:SSL
routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:478:


Here is for smtps
~~~~~~~~~~~~~~~

./check_tcp -H localhost -p 465
TCP OK - 0.001 second response time on port 465
|time=0.000886s;0.000000;0.000000;0.000000;10.000000

./check_tcp -H localhost -p 465 -S
TCP OK - 0.119 second response time on port 465
|time=0.118984s;0.000000;0.000000;0.000000;10.000000
