Re: [pysnmp-users] Example of SNMPv3 SET on remote

[Johan G. <joh...@gm...>]

Hi Ilya,
Yes, I need to remotely configure SNMPv3 / USM user via SNMP.
Thank you for the RFC reference and will look at that today. Is there
anything in pysnmp that makers this a little easier?
Can you please tell me if this OID makes any sense?
1: snmpTargetAddrTAddress.116.104.111.115.116.45.57.56.51.50.48.57.51.54.57
(TAddress) 0A.00.00.E7.00.A2 (hex)

I would expect a simple index number after snmpTargetAddrTAddress, but this
weird string comes back, which is the target IP address and port number.

Cheers
Johan
