secret key(s) for each of the users and delete the
createUser
lines from the file. It will then write
the secret key(s) to the file. These lines begin with the string,
usmUser
. In this way, un-encrypted
passwords are not stored on the system.
IMPORTANT
To generate new keys, stop the
snmpd
process, delete the existing
usmUser
key lines from the file
/boot/net-snmp/snmpd.conf and then add new
createUser
lines. Then re-boot the system.
This example gives the simplest configuration to begin using SNMPv3 but doesn’t make use of the
full capabilities of the VACM in defining groups and views for fine-grained access control. The fac-
tory default /etc/snmpd.conf file contains commented blocks of lines that can be uncommented to give
you a basic configuration that uses the User-based Security Model (USM) described in RFC-2274 and
the View-based Access Control Model (VACM) described in RFC-2275. The comments included in
the file should help you in modifying it for your specific requirements.
