安裝 fail2ban Agent 的方式

返回 Ubuntu 20.04 / CentOS7 安裝 LibreNMS 程序

這是 SNMP Extend

至 fail2ban 主機內安裝

wget https://github.com/librenms/librenms-agent/raw/master/snmp/fail2ban -O /etc/snmp/fail2ban
chmod +x /etc/snmp/fail2ban

確認 fail2ban 可以正確執行

/etc/snmp/fail2ban

如果正確執行應該可以看到類似的訊息

{"version":"1","error":"0","errorString":"fail2ban-client exited with 0","data":{"jails":{"roundcube-iredmail":"0","postfix-pregreet-iredmail":"1","postfix-iredmail":"0","dovecot-iredmail":"0","sshd":"0","nginx-http-auth":"0"},"total":1}}

修改 snmpd 設定

vi /etc/snmp/snmpd.conf

:
extend fail2ban /etc/snmp/fail2ban

重新啟動 snmpd

systemctl restart snmpd
