Nagios Support Forum

Hi All,

Am getting Unknown username error when setting up snmp v3 for Nagios Core.

I'll appreciate any assistance I'll get.
See below for output.

[ root on pts/0 ] (1005) # /usr/bin/net-snmp-create-v3-user -a password testuser
adding the following line to /var/lib/net-snmp/snmpd.conf:
createUser testuser MD5 "password" DES
adding the following line to /etc/snmp/snmpd.conf:
rwuser testuser
[ root on pts/0 ] (1006) # /etc/init.d/snmpd start
Starting snmpd: [ OK ]
[ root on pts/0 ] (1007) #

[ root on pts/0 ] (1008) # snmpwalk -v 3 -u testuser -a MD5 -A "password" -x DES -X "password" -l authPriv 10.255.1.18 > test3
snmpwalk: Unknown user name

i am also new to Nagios Core, i dont know how can i help you...but,

[ root on pts/0 ] (1004) # /usr/bin/net-snmp-config --create-snmpv3-user -a password testuser
zsh: no such file or directory: /usr/bin/net-snmp-config

Could you check where that file is?

[ root on pts/0 ] (1004) # find / -name net-snmp-config

Thanks.

Regarding net-snmp-config --create-snmpv3-user -a password testuser, you can ignore that as it turned out my CentOS version does not support that, but does support /usr/bin/net-snmp-create-v3-user -a password testuser.

Don't know why am getting the unknown username error.


Kind regards
