I recently started to play with Scotty 3.0.0, specifically the SNMPv3
usm stuff, I was not able to get authentication working, when I
dig through the email archive, i found this email which state that
the authen/priv stuff is not supported yet. Any time frame
on usm support?
I also notice a problem with the way Scotty command generator
handles REPORT, this may be a know issue, but I will mention
it anyway, when I send a SNMP request with authentication
enabled, the agent sends back a REPORT indicating
usmStatsWrongDigests, however, Scotty crash when it sees
a REPORT being send to the generator.
