Can it be done? If not, what do most people do when opening the netBIOS ports for samba (those who use samba, that is)? I assume, even though it only buys a speedbump, most people only open the netBIOS ports to the local net. Manual editing of /etc/sysconfig/iptables (in spite of system-config-securitylevel warning away from that)? Incidentally, when adding rules from the shell, I seem to have noticed that you can't specify multiple protocols and multiple ports in the same line like iptables -A INPUT -p ALL -i eth0 -s 10.5.0.0/22 --destination-port 137:139 -j ACCEPT Seems that -p All and --destination-port start:end conflict with each other. Am I imagining things? -- Joel <rees@xxxxxxxxxxx>
