Re: mib2c for oid type cause segmentation fault, e.g. etherStatsDataSource

[Emi . Yanagi]

This is hard-coded just as the piece of code I copy&pasted in my email.
Please notice the following error happened before the error message in your email.

RMON-MIB::etherStatsDataSource = Wrong Type (should be OBJECT IDENTIFIER): Variable has bad type

I attached the head file etherStatsTable.h.
(See attached file: etherStatsTable.h)

Thanks.

When is this done? Is this a hard-coded t hing, or is this value being set
during processing of a SET request?

Can you post the data context definition from the header?

EYC> results: RMON-MIB::etherStatsDataSource.1 = OID: SNMPv2-SMI::org

This result seems to indicate the the copy wasn't successful, as it is a much
shorter OID.

You are lost in a twisty maze of little standards, all different.
