Re: Latest v3 configuration documentation

Thanks Kalim, that worked.

Just for reference to anyone else on the list. I started fresh from a clean
install of net-snmp (Embedded linux build of yocto poky with net-snmp
included)

Booted my image

systemctl stop snmpd.service
net-snmp-config --create-snmpv3-user -a "testuser1ABCD" testuser1
systemctl start snmpd.service
snmpget -v 3 -u testuser1 -l authNoPriv -a MD5 -A testuser1ABCD localhost
sysUpTime.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (416903) 1:09:29.03

After the restart the config files are:

cat /usr/share/snmp/snmpd.conf
rwuser testuser1

cat /var/lib/net-snmp/snmpd.conf
#
# net-snmp (or ucd-snmp) persistent data file.
