Log et service
Comme vous le savez, le raspberry tourne sur une SDcard, et cette mémoire flash n’aime pas trop les écritures à outrance.
Je vais donc essayer de trouver des solutions pour limiter les logs qui ne sont pas importants.
Les logs

# find -mtime -1 -type f -exec ls -l {} \;

A peine un port ssh ouvert sur la toile que déjà des milliers de tentative de connexions qui génère des logs à n’en plus finir.
On va donc modifier le niveau de verbosité des logs de sshd
LogLevel
Donne le niveau de verbosité utilisé lors de l’enregistrement des messages du démon sshd Les valeurs possibles sont : QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2 and DEBUG3.
Par défaut INFO. DEBUG et DEBUG1 sont équivalents. DEBUG2 et DEBUG3 spécifient des niveaux plus élevés de sortie de débogage. L’enregistrement à l’aide d’un niveau DEBUG a tendance à empiéter sur la vie privée des utilisateurs et n’est pas recommandé.
vi /etc/ssh/sshd_config LogLevel QUIET service ssh reload
Inconvénient, plus de trace en cas de piratage, assurez vous d’avoir un bon mot de passe.
voir aussi dans /etc/rsyslog.conf
Commenter la ligne suivante pour ne plus rien recevoir dans /var/log/auth.log
#auth,authpriv.* /var/log/auth.log
et relancez le service des journaux
service rsyslog restart

Dans auth.log il y a aussi un paquet de ligne venant de cron

1ère méthode trouvé sur le net mais qui ne marche pas pour moi
Pour éviter ça, modifiez /etc/pam.d/common-session-noninteractive
vi /etc/pam.d/common-session-noninteractive
après la ligne
session required pam_unix.so
ajoutez
session [success=1 default=ignore] pam_succeed_if.so service in cron quiet use_uid
Redémarrez le service crond
service cron restart
2ème méthode qui marche pour moi :)
Configurer le rsyslog pour exclure ce type d’entrée dans les logs. Editez le fichier /etc/rsyslog.conf
vi /etc/rsyslog.conf
Modifiez la ligne
auth,authpriv.* /var/log/auth.log
par
:msg, contains, "pam_unix(cron:session)" ~ auth,authpriv.* /var/log/auth.log
et redémarrez le service des journaux
service rsyslog restart

Rien trouvé de concret sur le net à part configurer son réseau en ip static ce dont je n’ai pas envie de faire.
Ma solution un peu brut mais qui marche est de faire un
killall dhclient
