braa - network utility - change C-program source code

Changes required to attached C source code. Braa utility generates concurrent SNMPGET or SNMPWALK to multiple hosts. This utilility can take arguments from the file as below # braa -f "source_file" Source file for the program contain following lines public@[login to view URL]:.1.3.6.1.2.1.2.2.1.10.3 public@[login to view URL]:.1.3.6.1.2.1.2.2.1.16.3 where - "public" is SNMP RO Community string - "192.168.1.1" destination IP Address - ".1.3.6.1.2.1.2.2.1.10.3" and ".1.3.6.1.2.1.2.2.1.16.3" OIDs - IfInOctets and IfOutOctets - in OID last integer is the Interface IfIndex in above case both In and Out Octets refer to Interface Ethernet 0 (ifIndex 3) If we run braa -f "source_file" The result looks like below [login to view URL]:64ms:.1.3.6.1.2.1.2.2.1.10.3:2491108168 [login to view URL]:64ms:.1.3.6.1.2.1.2.2.1.16.3:290116724 Where - "192.168.1.1" - destination IP address - "64ms" - Ping RTT - ".1.3.6.1.2.1.2.2.1.10.3" relevant OID in this case IfInOctets - "2491108168" current counter reading In OID ".1.3.6.1.2.1.2.2.1.10.3" ending 3 is the interface IfIndex which refers to Interfac Ethernet 0 so in general form OID format for InOctets is ".1.3.6.1.2.1.2.2.1.10.IfIndex", where IfIndex again in above case is 3 The length on ifindex field is limited to 8 digits, for example IfIndex of 13423234 is OK but ifindex of 413423234 is over 8 digit and it defaults to some 8 digit number, similar to 16670000, I need to make this program to be compatible with IfIndex which is over 8 digits in length, for example 4334344435 Source code is attached. to compile this utility undex linux just run tar xvf [login to view URL] cd braa-0.8 make the resulting file is called braa, which is the actual executable.
