Hi All,

When creating new user for snmpv3 using net-snmp-create-v3-user command,

# net-snmp-create-v3-user -A asdfghjkl -X qwertyuio -x DES -a MD5 abcd
adding the following line to /var/lib/net-snmp/snmpd.conf:
createUser abcd MD5 "asdfghjkl" DES qwertyuio
adding the following line to /etc/snmp/snmpd.conf:
rwuser abcd

what is difference in the files /var/net-snmp/snmpd/conf( in some tutorials
they have mentioned this file) and /var/lib/net-snmp/snmpd.conf

--
Thanks,
Pranesh

Hi,

Both /var/net-snmp/snmpd/conf and /var/lib/net-snmp/snmpd.conf are snmp
persistent config files , only snmp persistent
directory are different.
I have seen latest version of net-snmp set '/var/lib/net-snmp/' as default
snmp persistent directory and few (may be old)
net-snmp sets '/var/net-snmp/' as default persistent directory.

Check default persistent directory in config options 'net-snmp-config
--configure'

Thanks,

Hi Pranesh,

User either net-snmp-create-v3-user or 'createUser' entry to create snmpv3
user , but not both I guess.

Are you following below steps
1. stop snmpd
2. add createUser entry in /var/lib/net-snmp/snmpd.conf and rwuser/rouser
entry in custom snmpd.conf
3. start snmpd
start snmpd in debug mode to check more details.

Thanks ,
