How to remedy? You can add the following two lines to /etc/sysctl.conf: net.inet.tcp.blackhole=2 net.inet.udp.blackhole=1 ...and reboot or type, as root, sysctl -w net.inet.tcp.blackhole=2 sysctl -w net.inet.udp.blackhole=1 > > Or do I need to 'deconfigure' em1? How can I do that? Edit /etc/rc.conf manually, either using ee or vi and comment out the lines you don't want active. You have connected the two network cards to the same switch, yes? don't do that. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "Failure is the opportunity to begin again more intelligently." --Henry Ford
