ping plusieurs IP en utilisant bash?

J'ai 10 numéros IP que je dois tester quotidiennement pour vérifier, comment je peux le faire en utilisant le script BASH. Pour que je puisse automatiser cette tâche en utilisant cron. Je veux uniquement le script BASH.

Je vous remercie.

Comme votre plage ip n'a pas de symétrie et qu'il n'y a que 10 nœuds, je suggère de les répertorier dans un fichier texte. Je considère que le fichier contenant la liste est celui list.txtqui contient la liste des ip un à chaque ligne comme indiqué ci-dessous,

10.12.13.14
172.15.48.3
192.168.45.54
...
48.114.78.227

Vous pouvez utiliser ce script,

#!/bin/bash
# Program name: pingall.sh
date
cat /path/to/list.txt |  while read output
do
    ping -c 1 "$output" > /dev/null
    if [ $? -eq 0 ]; then
    echo "node $output is up" 
    else
    echo "node $output is down"
    fi
done

Pour mettre à jour l'état d'exécution de vos nœuds à un intervalle de 30 minutes, utilisez crontab,

*/30 * * * * /path/to/pingall.sh > /path/to/log.txt

Sortie de log.txt

$ cat /path/to/log.txt

node 10.12.13.14 is up
node 172.15.48.3 is up
node 192.168.45.54 is up
...
node 48.114.78.227 is down

#!/bin/bash
while read hostname
do
ping -c 1 -t 1 "$hostname" > /dev/null 2>&1 && 
echo "Ping Status of $hostname : Success" || 
echo "Ping Status of $hostname : Failed" 
done < host.txt

$ cat host.txt

host1.example.com
192.168.0.123
8.8.8.8
...
...
google.com

Vérifiez ce script.

   #!/bin/bash
    for i in `seq ${2} ${3}`
    do
        ping -c 1 ${1}.${i} > /dev/null 2>&1
        if [ $? -eq 0 ]; then
            echo "${1}.${i} responded."
        else
            echo "${1}.${i} did not respond."
        fi
    done

Pour exécuter ./script 192.168.1 0 10 par exemple, cela vérifiera les ips 192.168.1.0 à 192.168.1.10 et l'écho a répondu si le ping est correct et n'a pas répondu sinon.

NB: Vous pouvez remplacer $ 1 $ 2 $ 3 par des variables statiques si la plage et les IP sont toujours les mêmes.

Supposons que vous disposez de 5 adresses IP (pour réduire la réponse uniquement), puis vous pouvez

#!/usr/bin/bash    
for i in xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxxx 
do
ping -c 5 $i
done

Remarque: Pas de crochets, pas de virgules (,) entre les IP.

J'espère que cela pourra aider.

echo 192.168.1.1 192.168.1.2 192.168.1.3 | xargs -n1 ping -w 1

ou avec grep, voir uniquement les nœuds non ping

echo 192.168.1.1 192.168.1.2 192.168.1.3 | xargs -n1 ping -w 1 | grep -b1 100

bien

Aussi simple que cela: utiliser parallel --gnu commande puis votre commande.
