Hello,

> Check your /etc/resolv.conf. Are there any dead nameservers in it?

Resolv.conf :
rayleigh:[~] > cat /etc/resolv.conf
search systella.fr
nameserver 192.168.0.128

	This server runs a bind9 daemon.

rayleigh:[~] > ping dnsbl.sorbs.net

	And this bind9 daemon works fine (for a long time...).
