Decode bootfiles with numeric OIDs is not working (option “-o”)

[sergessn]

I tried to decode my bootfiles in docsis 098-dev with option “-o” and don't see numeric OIDs on outputs. I always see OID names.

$ docsis098 -d test.bin
Main
{
NetworkAccess 1;
SnmpMibObject docsDevEvControl.0 Integer 1; /* resetLog /
SnmpMibObject ifAdminStatus.1 Integer 1; / up /
$
$ docsis098 -o -d test.bin
Main
{
NetworkAccess 1;
SnmpMibObject docsDevEvControl.0 Integer 1; / resetLog /
SnmpMibObject ifAdminStatus.1 Integer 1; / up */
$

Please fix the issue with decoding bootfiles with numeric OIDs.

Thanks, will take a look.

Sergey, unfortunately I cannot reproduce this.

Adrian,

I need to see OID numbers for all SnmpMibObjects with "-o"
A few minutes ago I downloaded again the last sources from github and compiled a docsis 0.9.8-dev.
I decoded my bootfile with the last version:

./docsis -d cm.bin
Main
{
NetworkAccess 1;
SnmpMibObject docsDevEvControl.0 Integer 1; /* resetLog /
SnmpMibObject ifAdminStatus.1 Integer 1; / up */
SnmpMibObject enterprises.4413.2.2.2.1.6.1.5.0 Integer 122;
SnmpMibObject docsDevNmAccessIp.16 IPAddress 0.0.0.0;
SnmpMibObject docsDevNmAccessIpMask.16 IPAddress 0.0.0.0;

./docsis -o -d cm.bin
Main
{
NetworkAccess 1;
SnmpMibObject docsDevEvControl.0 Integer 1; /* resetLog /
SnmpMibObject ifAdminStatus.1 Integer 1; / up */
SnmpMibObject enterprises.4413.2.2.2.1.6.1.5.0 Integer 122;
SnmpMibObject docsDevNmAccessIp.16 IPAddress 0.0.0.0;

As you can see I don't have any changes and differences in output with “-o” and without “-o”

I compile and use docsis 0.9.8-dev on Centos 5.11 server.
Will you help my compile logs or something else?

[AdrianSimionov]

Please add a complete decoded config file. I will use that file for more tests.
The decoding is handled by libsnmp-dev libraries and I hope to be just a setting somewhere.

This is my test bootfile decoded with 0.9.8-dev.

I checked the source code and -o option does not do what we expected it to do. I think it was a misunderstanding into the description of that option. What it will do is that it will not load the MIB files which are loaded by default.

By not loading the MIBs, some of the OIDs will look more numerical, but it was never supposed to be a complete numerical option.

I will convert this into a feature request as we need another option together with -o to specifically make it look like:

$ snmptranslate -On SNMPv2-MIB::sysUpTime.0
.1.3.6.1.2.1.1.3.0

Is this what you are looking for?

I understand the real need for -o option especially when you are working with PacketCable / EuroPacketCable configuration files.

[sergessn]

Thanks for researching.
Yes, it is that I'm looking (complete numerical option).
It will be perfect to have this new feature in docsis.

[AdrianSimionov]

Sergey, I think I finally have this fixed. Sorry that it took me so long but I had to learn A LOT about net-snmp libraries first.

Please download and compile the following code:

https://github.com/AdrianSimionov/docsis/archive/num_oid.zip

Here is how the output will look now:

$ ./docsis -d test.cm
Main 
{
    MtaConfigDelimiter 1;
    SnmpMibObject pktcSigDefCallSigTos.0 Integer 26;
    SnmpMibObject pktcSigDefMediaStreamTos.0 Integer 46;

    SnmpMibObject pktcNcsEndPntConfigCallAgentId.9 String "[192.168.28.40]";
    SnmpMibObject pktcNcsEndPntConfigCallAgentId.10 String "[192.168.28.40]";
    SnmpMibObject pktcMtaDevEnabled.0 Integer 1; /* true */
    SnmpMibObject pktcNcsEndPntConfigCallAgentUdpPort.9 Integer 2427;

    SnmpMibObject pktcNcsEndPntConfigMWD.10 Integer 2;
    SnmpMibObject pktcSigDevRgCadence.0 HexString 0x003ff00000000000;
    MtaConfigDelimiter 255;
}

$ ./docsis -o -d test.cm
Main 
{
    MtaConfigDelimiter 1;
    SnmpMibObject .1.3.6.1.4.1.4491.2.2.2.1.1.8.0 Integer 26;
    SnmpMibObject .1.3.6.1.4.1.4491.2.2.2.1.1.9.0 Integer 46;
    SnmpMibObject .1.3.6.1.4.1.4491.2.2.2.1.1.10.0 Integer 2;
    SnmpMibObject .1.3.6.1.4.1.4491.2.2.2.1.2.1.1.1.9 String "[192.168.28.40]";
    SnmpMibObject .1.3.6.1.4.1.4491.2.2.2.1.2.1.1.1.10 String "[192.168.28.40]";
    SnmpMibObject .1.3.6.1.4.1.4491.2.2.1.1.1.7.0 Integer 1;
    SnmpMibObject .1.3.6.1.4.1.4491.2.2.2.1.2.1.1.2.9 Integer 2427;
    SnmpMibObject .1.3.6.1.4.1.4491.2.2.2.1.2.1.1.2.10 Integer 2427;
    SnmpMibObject .1.3.6.1.4.1.4491.2.2.2.1.2.1.1.18.9 Integer 2;
    SnmpMibObject .1.3.6.1.4.1.4491.2.2.2.1.2.1.1.18.10 Integer 2;
    SnmpMibObject .1.3.6.1.4.1.4491.2.2.2.1.1.22.0 HexString 0x003ff00000000000;
    MtaConfigDelimiter 255;
}

Give it a try, let me know if other changes are needed (maybe add this with a new argument?) and if everything is OK me or Richard will accept the changes.

This is a really nice feature in my opinion, especially when working with PacketCable configuration files.
