Here you go, all menu items have registration files stored in
/usr/OV/registration/C. There is a good write-up about registration files in
the Programmers Guide, its worth a read. In there are the files that "build"
the menus. I searched for the TCP connect Test and found it in the following
file: /usr/OV/registration/C/ovip/NNM-IP.tbl.

In that file, if you search for TCP you will find:

      <100> "IP/TCP/SNMP Connectivity..." _I  f.action 'Test All Protocols';

This is essentially the menu entry. Then you see f.action 'Test All
Protocols'. This is going to be an action described later in the file.
Searching for "Test All Protocols" in the file takes me to this:

    Action 'Test All Protocols' {
        MinSelected 0 ;
        SelectionRule   ((isNode || isInterface) && isIP) ;
        CallbackArgs '-helpFile ovip/OVW/Functions/netProtocols \
                      -appendSelectList -appendSelectListToTitle \
                      -commandHeading \"Node                     ICMP Echo   
     TCP Connect          SNMP Get\" \
                      -dataLine 2 -commandTitle \"Test All Protocols\" \
                      -iconName \"Test Protocols\" \
                      -cmd /usr/OV/bin/netcheck -e'

This looks fairly comlicated, but in the end, we just want to look at this

                      -cmd /usr/OV/bin/netcheck -e'

This is the acutal command that will be run when the menu item is clicked.
So I took a look at the netcheck command:

zodiac:/usr/OV/registration/C# netcheck
Usage: netcheck [-elu] [-o optname=optval] [-t test] host ...
       -e      Print verbose error messages to stderr.
       -l      List available options and tests.
       -o      Specify an option value.
       -t      Run the named test (default is all tests).
       -u      Unbuffer stdout.
               At least one host must be specified.
zodiac:/usr/OV/registration/C# netcheck -l
TESTS:  ip      tcp     snmp
OPTION               DEFAULT            
icmpTimeout          1                  
icmpTries            5                  
tcpPort              telnet             
snmpTimeout          3                  
snmpTries            3                  
snmpVar              system.sysDescr.0  

From here I tested a bit and found that if you run:

netcheck -e -l tcpPort=22 <hostname>

You will get the results you desire. The hostname is not required in
the registration file, NetView will take care of that ifself. 

So the bottom line is this. In the file above, if you change the line:

                      -cmd /usr/OV/bin/netcheck -e'
                      -cmd /usr/OV/bin/netcheck -e -l tcpPort=22'

It should give you the desired results.

A few quick notes:
If all your devices do not have ssh running, it will fail on those. You might
want to consider creating an additional menu item to test those types of
devices, and leave this one unchanged.

Be careful when editing these files and make sure you make a backup.
