R: R: Warning: Failed to connect to the agentx master agent (/var /ag ent x/master): Unknown host (/var/agentx/master) (Connection refused)

Ok, thank you very much. I solved the problem. 
The problem was: 

Under /var/agentx I had a directory called master, and not a file. 

So what I did was: 
1) Remove the master directory 
2) touch master 
3) start master agent (without AgentXSocket myserver:5000 in conf file)
and    
   it worked 
4) start the subagent, and it worked 
5) perform a snmpget , and it worked. 

Thank you again for your precious support. 

Best Regards.

Let's see if we can get a "standard" installation working, 
shall we?

      ^^^^^^^^^^^^^^^^^^^^^^^^ 

Note that last error message. 
That seems to imply that you may already have an 
AgentX-capable SNMP agent running on the system. 


Try shutting down both your master agent and your subagent. 
Check the directory /var/agentx - what does it contain ? 
    ("ls -l /var/agentx") 

Check the running processes - is there another SNMP agent ? 
    ("ps -ef | grep -i snmp"  or "ps -aux | grep -i snmp")
