Hi, I have the 4.0firewall, and the firewall log shows a some connections accepted on port 0: Packet log : input ACCEPT eth1 PROTO=1 a.b.c.8 x.y.z.0 L=68 ..... I think it shouldn't be posible since port 0 is reserved.. could this be a misconfuguration in the firewall?? , or even a little bug.... Thks you all! karlos

Proto=1 is ICMP (Internet Control Message Protocol), see /etc/protocols. Message Type 0 is ICMP echo_reply, Message type 8 is ICMP echo_request. So, someone has pinged your host. best regards, Rainer -- Rainer Link | SuSE - The Linux Experts link@suse.de | Developer of A Mail Virus Scanner (amavis.org) www.suse.de | Founder OpenAntiVirus Project (www.openantivirus.org)
