Cisco Mibs Brake when using mib names

[seanfariacustomink]

If I use the Cisco mibs by name (i.e. ciscoMemoryPoolFree), I would get the following error:

"errorMessage": "invalid OBJECT ID 48.1.1.1.7.7: first num too large",
"errorType": "Function<OpenSSL::ASN1::ASN1Error>"

If I use the OID it works and provides the correct feedback

[HoneyryderChuck]

Thx for the report.

Is the oid from the error message correct? What's the difference in the logs when you turn on the debug output?

[seanfariacustomink]

Yes the mib is correct, but it seems the first part of it gets cut off see below:

OID = 1.3.6.1.4.1.9.9.48.1.1.1.6 = CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolFree
OID = 1.3.6.1.4.1.9.9.48.1.1.1.7 = CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolLargestFree

[HoneyryderChuck]

That looks like a mib parsing issue. Do you think you can write a patch to add support for that case? Or alternatively, can you upload the cisco mibfile, so I can do it when I have the time?

[seanfariacustomink]

Sorry still a newbie, I can give it a shot.

List of cisco mibs:

Actual mib in question:

[HoneyryderChuck]

thx, I'll see what I can do.

[HoneyryderChuck]

It seems that you are missing a MIB file in the mibdir, particularly this one. I could reproduce it by doing:

require "netsnmp"
require "netsnmp/mib/parser"

NETSNMP::MIB.load(File.join(__dir__, "CISCO-SMI.my"))
NETSNMP::MIB.load(File.join(__dir__, "CISCO-MEMORY-POOL-MIB.txt"))

puts NETSNMP::MIB.oid("ciscoMemoryPoolFree")
# => 1.3.6.1.4.1.9.9.48.1.1.1.6

Can you confirm that you're missing the file?

[seanfariacustomink]

Interesting!!! I did have it like this:

  NETSNMP::MIB.load('./CISCO-MEMORY-POOL-MIB.my')
  NETSNMP::MIB.load('./CISCO-PROCESS-MIB.my')
  NETSNMP::MIB.load('./CISCO-PROCESS-CAPABILITY.my')
  NETSNMP::MIB.load('./CISCO-REMOTE-ACCESS-MONITOR-MIB.my')
  NETSNMP::MIB.load('./CISCO-FIREWALL-MIB.my')
  NETSNMP::MIB.load('./CISCO-QOS-PIB-MIB.my')
  NETSNMP::MIB.load('./CISCO-SMI.my')
  NETSNMP::MIB.load('./powernet441.mib')

hmm let me try to load the entire directory some how, but the error does change when I use the following:

NETSNMP::MIB.load(File.join(__dir__, "CISCO-SMI.my"))
NETSNMP::MIB.load(File.join(__dir__, "CISCO-MEMORY-POOL-MIB.txt"))

Let me try this and get back to you today.

After changing the all of the above to NETSNMP::MIB.load(File.join(__dir__, "MIB")) format it states the following error:

"errorMessage": "Failed to match sequence (SPACE{0, } MODULES?) at line 16 char 1.", "errorType": "Function<Parslet::ParseFailed>",

[seanfariacustomink]

After checking it with another MIB CISCO-PROCESS-MIB.my

"errorMessage": "invalid OBJECT ID 109.1.1.1.1.4.1: invalid separator", "errorType": "Function<OpenSSL::ASN1::ASN1Error>",

Above Error:
"CISCO-PROCESS-MIB::cpmCPUTotal1min.1"

No error:
1.3.6.1.4.1.9.9.109.1.1.1.1.4

[HoneyryderChuck]

so if I understood correctly, there was an error parsing the "CISCO-PROCESS-MIB.my" file?

[seanfariacustomink]

Yes that's correct

[HoneyryderChuck]

can you try with the master branch? I'm able to load those files already. Perhaps this has been fixed with my last week's patch.

[seanfariacustomink]

Sorry, i do not see any change still the following error:

"errorMessage": "invalid OBJECT ID 42.1.3.5.1.34: first num too large",
"errorType": "Function<OpenSSL::ASN1::ASN1Error>"

"errorMessage": "invalid OBJECT ID 109.1.1.1.1.4.1: invalid separator",
"errorType": "Function<OpenSSL::ASN1::ASN1Error>",

I am using the ruby gem and i don't see a new version added could that be it?

[HoneyryderChuck]

yes, that should be it. If you're using a gemfile, put this there instead:

gem "netsmp", git: "https://github.com/swisscom/ruby-netsnmp.git" #, branch: "master"

and execute your script with "bundle exec".

[HoneyryderChuck]

@seanfariacustomink any updates?

[seanfariacustomink]

Hey, @HoneyryderChuck sorry for the delay got sick. Now i can't use any Cisco mibs name or oid.
With oid:
"errorMessage": "cannot load such file -- netsnmp", "errorType": "Init<LoadError>",

With Name:
"errorMessage": "cannot load such file -- netsnmp", "errorType": "Init<LoadError>",

[HoneyryderChuck]

did you blindly copy-paste my statement above? because it contains a type (netsnmp, not netsmp).

[seanfariacustomink]

no I did not:

do i need this like before?
require "netsnmp/mib/parser"

[HoneyryderChuck]

apologies for the delay, seems I missed the notification.

Nothing strikes me out of the ordinary for that error to happen.
