RE: [Mibble-users] retrieving names of fields in NOTIFICATION-TYPE(traps)

[Hall, Matthew]

Hello again Per and the list,

I have some code I've tested on numerous vendors and in general bullet-proofed. 
So now I'm releasing it to the world. I know it's a bit of a kludge but it will 
enumerate and print out the data on traps in an easy to use format. I think it 
can be used as an example of how to perform simple MIB reading tasks.

I deliberately made the interface as brain-dead as possible. One just lists the 
MIB names on the command line and the tool will take it from there. I suppose 
it could use a usage message but the code is simple enough as is.

Thanks,
Matthew Hall
