Change SNMP community name
- Edit file /etc/snmnp/snmpd.conf
- Change public into the string recommunity on your own
- Save changes
- Restart SNMP daemon - systemctl restart snmpd
Move on SNMPv3
- Stop SNMP daemon - systemctl stop snmpd
- Launch the command - net-snmp-config --create-snmpv3-user -ro -a "authpass" -x "privpass" -X AES -A SHA "user"
- "authpass" is the private key/password for generating HMAC when connecting to snmpd, "privpass" is the private key/password for encrypting snmp traffic, "user" is the username for snmpd.
- "authpass" and "privpass" we can say passwords, which should be generated by you own
- "user" - user name for snmpd
This command will make mpdifications into two files - /etc/snmp/snmpd.conf and /var/lib/net-snmp/snmpd.conf
- Restart SVM
