in here, the handlers.cpp file defines the remote SSH port 22.
Also here are a group of parameters passed into H_SSHCommand()

I am interested in variable/pointer set with this function _tcschr(hostName, _T(':'));

/**
 * Generic handler to execute command on any host
 */
LONG H_SSHCommand(const TCHAR *param, const TCHAR *arg, TCHAR *value, AbstractCommSession *session)
{
   TCHAR hostName[256], login[64], password[64], command[256];
   if (!AgentGetParameterArg(param, 1, hostName, 256) ||
       !AgentGetParameterArg(param, 2, login, 64) ||
       !AgentGetParameterArg(param, 3, password, 64) ||
       !AgentGetParameterArg(param, 4, command, 256))
      return SYSINFO_RC_UNSUPPORTED;

   UINT16 port = 22;
   TCHAR *p = _tcschr(hostName, _T(':'));
   if (p != NULL)
   {
      *p = 0;
      p++;
      port = (UINT16)_tcstoul(p, NULL, 10);
   }

We understand from documentation and from forums to use SSH.Command() -- Is anyone using the alternative port feature? I assume it should be used in DCI collection for Data Parameter (as an SSH origin) with this example:

SSH.Command(100.64.45.218:1916,tiger,lemur,"cat /tmp/run/stats/wireless.json")

Is this accurate? a packet trace reveals port 22 is used

... The command above works for ./bin/nxget but not for DCI collection. For that, i simply enter the command "cat /tmp/run..." but nxms connects to port 22
