hi,all I have encountered a problem: I can ping to another machine. Yet telnet and ftp port can not opened. So I thought it was a firewall problems. I compile the kernel with CONFIG_NETFILTER unselected. Still the same problem. When I restore all Netfilter configuration and use service iptables start, a message "iptables-restore failed in line 18". What's the problem? Jack Liu Jack_liu@xxxxxxxxx 2004-03-31
