проверить несколько серверов по ssh-ключу [закрыто]

Su servicio está escuchando solo en la dirección de loopback, 127.0.0.1.

Cuando realiza una conexión desde 192.168.0.21o cuando especifica la dirección ip, no funciona, ya que su servicio no está escuchando en ese ip.

Cuando usa hostnamedesde 192.168.0.12, funciona porque se conecta a la dirección de bucle invertido. Esto se debe a que primero buscará en su archivo de hosts, /etc/hosts, que tiene una entrada que apunta hostnamea su bucle invertidoip:127.0.0.1 master1.mycluster

Примерно так:

#!/bin/bash
# I assume "logfile" is the log file. If you just want the last run 
# in the log fil, use date> logfile.
# It is always a good idea to get a time stamp in this kind of logs.
date >> logfile 

# The read takes the input from servers.txt, which is done at the
# bottom using `done < servers.txt`.
# Some people like to do `cat servers.txt | while read -r hostname ; do`
# but they get negative comments on stackexchange :-)
while read -r hostname ; do

    # Test if the host is up with a simple ping
    # Throw away all output.
    if ping -c1 "$hostname"  > /dev/null 2>/dev/null; then

        # We now test if a host is up with a simple command, echo.
        # with -o PasswordAuthentication=no, we make sure that password
        # authentication is not used. Output the result to the logfile.
        if ssh  -o PasswordAuthentication=no "$hostname" echo ' '; then
            echo "OK - $hostname" >>logfile
        else
            echo "AArrrghhh $hostname" >> logfile
        fi
    else
        # I assumed you want some idea of how many servers are skipped.
        echo "skipped $hostname" >> logfile
    fi
done < servers.txt

Это быстрая запись, и, вероятно, потребуется некоторая настройка. Комментарии должны дать вам несколько советов о том, что проверить.

Это прекрасно :-)Я внес в него некоторые изменения;-)

Конвертировать private.ppk в private.pem:

$ apt install putty-tools
$ puttygen private.ppk -O private-openssh -o private.pem
$ eval `ssh-agent -s`
$ ssh-add priv_key.pem

И скрипт будет работать идеально
