Sorry very much for my stupidity. I don't know how to config iptables (but system-config-securitylevel :P) And I don't know how to use ethereal ether. I think at some point on the first connection to samba, windows SMB client must have used a port other than 139:tcp 445:tcp 137:udp and 138:udp ... ... I'm not sure about that Besides, does anyone have any experience on samba + iptables settings? Bob Chiodini wrote: >>It depends on how you set up your firewall. man iptables and search for >>LOG.
