[AGENT++] agent created with cmd_exe_mib doesnt' recognize the get request for OID 1.3.6.1.4.1.4976.6.1.2.2.2.1

Thu Dec 24 03:33:41 CET 2015

Dear Frank,
  Thanks for uploading the MIB docs on the site. They were quite helpful in
understanding  the code now.

My Goal was to run the 'date' command on the linux command line and get the
output back to the SNMP manager.

I tried initializing the MIB table cmdExecutionCmdEntry from the API as
below.

         MibTableRow* r =
cmdExecutionCmdEntry::instance->add_row("1.3.6.1.4.1.4976.6.1.2.2.2.1");
//got this from the MIB file
         OctetStr cmd="date";
         Vbx vb= new Vbx("1.3.6.1.4.1.4976.6.1.2.2.2.1.2","date");
         ((cmdExecutionCmdName*)r->get_nth(0))->set_value(vb);//setting the
variable binding with teh command name to be executed
        ((cmdExecutionCmdStatus*)r->get_nth(1))->set_state(1);//setting
state to be idle
        ((cmdExecutionCmdRunTime*)r->get_nth(2))->start();//initializing
teh start time
        ((cmdExecutionCmdRowStatus*)r->get_nth(3))->set_state(rowActive);

    When compiling I always get the error below.

agent.cpp:293:64: error: no matching function for call to
‘Agentpp::Vbx::Vbx(const char [31], const char [5])’
         Vbx vb= new Vbx("1.3.6.1.4.1.4976.6.1.2.2.2.1.2","date");

Query

1) Please help me construct the Variable Binding object to be passed for
initialing the row with respective values.

2) Can you help me with the command to set the same using SNMP SET request
without the use of API.
3) In your earlier reply you wanted me to set the RowStatus column. Should
the set be onto the entire row... and not just the column of the row ..??

Regards,
Ravi
