在客戶端編寫的一個(gè)腳本check_ssh_auto.sh

#!/bin/bash

a=`/bin/cat /etc/ssh/sshd_config | grep PasswordAuthentication | grep -v "^#" | awk '{print $2}'`

if [ "$a" = "yes" ]; then

echo "SSH authentication: WARNING Please amend the warning SSH authentication for key authentication;"

$(exit 1)

else

echo "SSH authentication: OK;"

$(exit 0)

客戶端執(zhí)行正常

nagios服務(wù)器測(cè)試執(zhí)行

/usr/local/nagios/libexec/check_nrpe -H 192.168.10.1 -c ssh_auth

提示NRPE: Unable to read output

解決方法

在客戶端修改文件

vi /etc/sudoers

注視這行

#Defaults requiretty

在root ALL=(ALL) ALL下面添加一行

nagios ALL=(ALL) NOPASSWD:/usr/local/nagios/libexec/*

修改nrpe配置文件/usr/local/nagios/etc/nrpe.cfg

command[ssh_auth]=/usr/bin/sudo /usr/local/nagios/libexec/check_ssh_auth.sh

重啟nrpe

服務(wù)器端再次測(cè)試

SSH authentication: OK;

向AI問(wèn)一下細(xì)節(jié)
