pingar vários IP's usando o bash?

Question

Eu tenho 10 números IP que eu tenho que pingar diariamente para verificação, como eu posso fazer isso usando o script BASH. Para que eu possa automatizar essa tarefa usando o cron. Eu quero apenas script BASH.

Obrigado.

    

Answer 1

Como seu intervalo de ip não tem simetria e há apenas 10 nós, sugiro listá-los em um arquivo de texto. Eu estou considerando que o arquivo contendo a lista é list.txt , que contém uma lista de ip em cada linha, como mostrado abaixo,

10.12.13.14
172.15.48.3
192.168.45.54
...
48.114.78.227

Você pode usar este 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

Para atualizar o status de execução de seus nós em um intervalo de 30 minutos, use em crontab,

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

Saída do log.txt

$ cat /path/to/log.txt
Fri Jan 31 15:06:01 IST 2014
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

    

Answer 2

#!/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

Answer 3

Verifique este 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

Para rodar ./script 192.168.1 0 10 por exemplo, isto irá verificar os ips 192.168.1.0 para 192.168.1.10 e echo respondeu se ping está ok e não respondeu se não.

NB: Você pode substituir $ 1 $ 2 $ 3 por variáveis estáticas se o intervalo e os IPs forem sempre os mesmos.

    

Answer 4

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

ou com o grep, veja apenas nós não ping

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

    

Answer 5

Bem

Simples assim: Use o comando parallel --gnu e depois o seu comando.

Obtenha os exemplos de IPs:

$ dig +trace google.com |ipx

127.0.0.1
127.0.0.1
199.7.91.13
199.7.91.13
192.48.79.30
192.48.79.30
173.194.33.161
173.194.33.165
173.194.33.163
173.194.33.164
173.194.33.174
173.194.33.160
173.194.33.167
173.194.33.166
173.194.33.162
173.194.33.169
173.194.33.168
216.239.32.10
216.239.32.10

$ parallel --gnu ping -c1 ::: 'dig +trace google.com |ipx'

Answer 6

Suponha que você tenha 5 IPs (para reduzir apenas a resposta) e, em seguida, pode executar ping com

#!/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

Nota: Não enrolar os colchetes, Sem vírgulas (,) entre os IPs.

Espero que ajude.
