Oh you're right, thanks for commemorate me of the subidentifier.

I tried a GET request like that: "snmpget.exe -v 2c -r 0 -m all -t 60 -c public
localhost .1.3.6.1.4.1.17524.1.1.0"
Output:
"Error in packet
Reason: (genError) A general failure occured
Failed object: FERRARI-ELECTRONIC-MIB::Productname.0"
The Master send the request only once but he resend it 5 times with a delay
under a second.
In my Subagent I call sometimes the routine "Sleep()" but only with a value of
between 2 and 5 (Milliseconds).
So this should not be the reason !?

I've get only debug code at these routines:
netsnmp_ds_set_string()
init_agent()
Both return zero.
I've included these SNMP headers:
net-snmp-config.h
net-snmp-includes.h
net-snmp-agent-includes.h
I thought that these headers or the routines in it handles the get request from
the master agent.
Or have I to write a function for that?!
Sorry if I'm to slow or a little bit slow-witted but this is my first project,
I'm programming since one year :)
Thanks
Julian
