Hello à toutes et tous,
Avec ce scripts, j’aimerais lancer ma connexion en dhcp derrière l’ont d’Orange .
Je suis loin de maîtriser l’écriture de scripts.
La preuve j’ai besoin d’aide 
#!/bin/bash
#Converti le fti
USERNAME=$1
AUTHSTRING=00:00:00:00:00:00:00:00:00:00:00:66:74:69:2f
for (( i=0; i<${#USERNAME}; i++ )); do
HEXCHAR=$(echo -n ${USERNAME:$i:1} | od -An -txC | xargs)
AUTHSTRING=${AUTHSTRING}:${HEXCHAR}
done
echo ${AUTHSTRING};

#Test 8 pings
sudo ping 8.8.8.8 -c8 -q
if [ $? != 1 ]; then
echo "connexion derrière ont opérationnel" >> /diagbox/web/tmp/ping.txt
else
echo "nok" >> /diagbox/web/tmp/ping.txt
fi
en cherchant sur la toile, j’ai trouvé comment remplacer la Livebox en utilisant le protocole DHCP.
Quand je le fais manuellement, ça fonctionne.
Mais mon script me sort une erreur 
root@diagbox:~# bash /diagbox/scripts_sh/speedtest_ont.sh adsl@adsl
/diagbox/scripts_sh/cnx_ont.sh: line 5: $'\r': command not found
/diagbox/scripts_sh/cnx_ont.sh: line 6: syntax error near unexpected token `$'do\r''
/diagbox/scripts_sh/cnx_ont.sh: line 6: `for (( i=0; i<${#USERNAME}; i++ ) '; do
Et je ne sais pas à quoi ça correspond lol.
Merci d’avance pour votre aide.
