There's no need to apologize to the 'gurus', helping Nagios users 
is what this list is all about.  However, to allow us to help you,
you must provide more information.  E.g.:

- When you say that a host is shown as DOWN, do you have problems only with
  this host (i.e., is the status for your other hosts displayed correctly)?
- What is your host config for host 192.168.1.5?
- What are your service checks for that host?
- What are your check command definitions?
- Does Nagios yield any warnings when you check the config with the -v
option?
- Did you run the Nagios plugins _as the Nagios user_ on the command line?  
  What was their exact output?
- Are you sure that the IP in the host definition is correct?
- Did you try out some suggestions from the FAQ?  What was the result?

I'm afraid I don't understand your following question:
> Is necesary activate external command to verify host status?
What part of the documentation are you referring to?  
What did you try?  Then what happened?  

HTH, kind regards,

PS:
It's perfectly OK if you don't understand all of the Nagios documentation
now.  
It's huge, and some things won't make sense until after you've played around

with the Nagios config for a while.
