Xinetd râle beaucoup

[jpourrez.nospam@free.fr]

Lorsque je me connecte à Internet, Xinetd m'envoie environ une dizaine
de lignes par minute lignes comme ci-dessous dans les fichiers de log :

Iptables est activé. Le site www.grc.com (Shields Up) m'indique que tous
les ports sont fermés.

Tout le trafic Internet se passe normalement (Web, FTP passif, pop3,
smtp, nntp, ntp,..)

Voici mes fichiers hosts.allow et hosts.deny :

# /etc/hosts.allow: list of hosts that are allowed to access the system.
#-- leafnode begin
leafnode: 127.0.0.1
#-- leafnode end
ALL: 127.0.0.1
sshd, smbd, proftpd, swat: 192.168.13.

# /etc/hosts.deny: list of hosts that are _not_ allowed to access the
ALL: ALL
#-- leafnode begin
leafnode: ALL
#-- leafnode end

Mon réseau local est bien en 192.168.13.0
J'ai aussi logchecks et snort qui tournent.

D'où proviennent toutes ces lignes d'erreur ?

Merci par avance.
