PASS OID and C++ SCRIPT

[Hernán Romano]

Hello Guys!

 

 I have a problem, It’s a new issue that I cannot figure it out and I
couldn’t find any documentation about this.

 

The situation is this,

   In my snmpd.conf file i have this line: " pass .1.3.6.1.4.1.6147.2.1
/usr/share/cacti/scripts/TDP/binarios/ClearCodeGroup2 "

 

Note: "ClearCodeGroup2" is a simple C++ script that have been compiled and
its code is this:

 

         #include <cstdio>

         #include <cstdlib>

         #include <iostream>

         #include <sstream>

         #include <string>

         #include <vector>

         #include <set>

         #include <map>

         #include <fstream>

 

           using namespace std;

 

          int main(int argc, char *argv[])

        {;

           

            cout<<".1.3.6.1.4.1.6147.2.1\n";

             cout<<"Integer32\n";

            cout<<"321224";

         return 0;

       }

 

This little program works EXCELLENT! As you can see:

 

    root@cacti:/usr/share/cacti/scripts/TDP/binarios# snmpget -m TDP-MIB -v
2c -c TM_Com_Pub localhost .1.3.6.1.4.1.6147.2.1

    TDP-MIB::ClearCodeGroup1 = INTEGER: 321224

 

...but when i try to read the value for the OID from a "…/anyfile.txt", 

 

    int main(int argc, char *argv[])

        {

            string comando;

           char valor;

            comando="cat …/anyfile.txt | grep \"ALL GTP PDP context\" | awk
'{pr$

 

            cout<<".1.3.6.1.4.1.6147.2.1\n";

             cout<<"Integer32\n";

            cout<<comando;

         return 0;

       }

 

 

 

…the snmpgetnext doesnt work anymore and gives me this error.

 

    root@cacti:/usr/share/cacti/scripts/TDP/binarios# snmpget -m TDP-MIB -v
2c -c TM_Com_Pub localhost .1.3.6.1.4.1.6147.2.1

    TDP-MIB::PDPContextsNumber = No Such Instance currently exists at this
OID

 

I have test my C++ Script, and it works like i want and return me this:

   root@cacti:/usr/share/cacti/scripts/TDP/binarios# ./ClearCodeGroup2

    .1.3.6.1.4.1.6147.2.1

    Integer32

    321224

 

It's seems that I’m forgetting something!! but i don’t know what. I hope you
can help me out with this.
