Your netmask for the ethernet interface does include the IP address of the SLIP peer. As long as the SLIP interface is up & running, its own host route gets precedence over the ethernet network route. However, if the modem drops carrier, the specific host route (this is the _remote_ IP address of the SLIP i/f) disappears, hence all further packets for this address default to the ethernet route, and the IP layers attempt to ARP for it on the ethernet. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
