Ho 10 numeri IP che devo fare quotidianamente il ping per controllare, come posso farlo usando lo script BASH. In modo che io possa automatizzare quell'attività usando cron. Voglio solo lo script BASH.
Grazie.

Risposte:
Poiché il tuo intervallo ip non ha simmetria e ci sono solo 10 nodi, suggerirei di elencarli in un file di testo. Sto considerando che il file che contiene l'elenco list.txt
contiene l'elenco di ip uno per ogni riga, come mostrato di seguito,
10.12.13.14
172.15.48.3
192.168.45.54
...
48.114.78.227
Puoi usare questo 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
Per aggiornare lo stato di esecuzione dei tuoi nodi a un intervallo di 30 minuti, utilizza crontab,
*/30 * * * * /path/to/pingall.sh > /path/to/log.txt
Output di 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
#!/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
Vedi:
http://www.thelinuxtips.com/2012/06/shell-script-to-ping-multiple-hosts/
Controlla questo 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
Per eseguire ./script 192.168.1 0 10, ad esempio, questo controllerà gli ips da 192.168.1.0 a 192.168.1.10 e l'eco ha risposto se il ping è ok e non ha risposto in caso contrario.
NB: puoi sostituire $ 1 $ 2 $ 3 con variabili statiche se l'intervallo e gli IP sono sempre gli stessi.
Supponiamo di avere 5 IP (per ridurre solo la risposta), quindi puoi effettuare il ping con
#!/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: non arricciare le parentesi, nessuna virgola (,) tra gli IP.
Spero possa aiutare.

lavoro, sarebbe necessario un mezzo per avvisare l'utente del risultato del lavoro o suggerisci qualcos'altro?
Bene
Semplice: usa il parallel --gnu
comando e poi il tuo comando.
