[rlug] Re: Monitor Internet Linux

[cristi]

Am un script bash (net.sh) care vreau sa-l rulez in fiecare minut.
Am bagat in /etc/crontab linia:
*    *    *    *    * root /etc/net.sh

dar vad ca nu ruleaza scriptul.
El ar trebuie ca in fiecare minut sa verifice in retea daca o anumita masina
se afla conectata.
In cazul in care aceasta nu este scoate un semnal sonor la speaker.
Ce trebuie adaugat la acesta ca sa mearga cum trebuie?


#!/bin/sh

clear
rez=$(ping -w2 -c 3 192.168.1.1 | grep "100\% loss");
if [[ -z $rez ]]; then
    echo $(date) "Servsal1 192.168.1.135 works"
else
    echo $(date) "Servsal1 192.168.1.135 doesn't work"
    echo -e "\a"
    sleep 1
    echo -e "\a"
    sleep 1
    echo -e "\a"
    sleep 3
    echo -e "\a"
    sleep 1
    echo -e "\a"
    sleep 1
    echo -e "\a"
    sleep 1
    echo -e "\a"
    sleep 1
    echo -e "\a"

fi


Meajul de eroare:
