Re: [pysnmp-users] Custom MIB files

[Ilya E. <il...@gl...>]

I could not compile your MIB because it seems to import both SMIv1 and SMIv2 types. Once I changed the SMIv1 IMPORTS:

     DisplayString
                        FROM RFC1213-MIB

for SMIv2 ones:

     DateAndTime, DisplayString, RowStatus, TruthValue, DisplayString
                        FROM SNMPv2-TC

It compiled successfully.

As for your other question — your code looks OK for as long as you actually iterate the generator you’ve created because this is when actual I/O happens:

    gen = nextCmd(…)
    for rsp in gen:
        print(rsp)

And SNMP agent at 169.254.81.145 is responding. You may also debug your script against public SNMP simulator:

   http://snmpsim.sourceforge.net/public-snmp-simulator.html

Though it does not implement your MIB.

There is another question I want to ask you about pysnmp as well, I did not get any response for the following command, do I do something obviously wrong? The snmp agent is configured and I was able to get correct response for ObjectIdentity('SNMPv2-MIB', 'system')
