[pysnmp-users] Problems encoding IP index instances?

[Camilo C. <jua...@im...>]

Hello all,

I am having some problems encoding indices instances to OIDs.

Here is the outcome when I try to run the example of the documentation resolving the tcpConnectionState instance. 

In [2]: tcpConnectionState_instance = ObjectIdentity('TCP-MIB', 'tcpConnectionState', 'ipv4', '195.218.254.105', 41511, 'ipv4', '194.67.1.250', 993)

In [3]: tcpConnectionState_instance.resolveWithMib(view.MibViewController(mibBuilder))

In [4]: tcpConnectionState_instance.getOid()
ObjectName('1.3.6.1.2.1.6.19.1.7.1.15.49.57.53.46.50.49.56.46.50.53.52.46.49.48.53.41511.1.12.49.57.52.46.54.55.46.49.46.50.53.48.993')

This is different from the 1.3.6.1.2.1.6.19.1.7.1.4.195.218.254.105.41511.1.4.194.67.1.250.993 (which is given as a result in the documentation). Other examples are actually encoded fine, so I am not sure if this is something local or a general problem. Can this be caused by something on the MIB file? 

Resolving the “correct” OID throws the next:

In [13]: tcpConnectionState_instance = ObjectIdentity('1.3.6.1.2.1.6.19.1.7.1.4.195.218.254.105.41511.1.4.194.67.1.250.993')

In [14]: tcpConnectionState_instance.resolveWithMib(view.MibViewController(mibBuilder)) 
ObjectIdentity('1.3.6.1.2.1.6.19.1.7.1.4.195.218.254.105.41511.1.4.194.67.1.250.993')

In [15]: tcpConnectionState_instance.prettyPrint()
"TCP-MIB::tcpConnectionState.'ipv4'.0xc3dafe69.41511.'ipv4'.0xc24301fa.993”

Thanks,
