My machine has suddenly started displaying this message SIOCADDRT - invalid argument. The network card is dtected and while booting up it shows up correctly I traced it to the two route commands in /etc/inet.d/network They are correct - as per the man, ifconfig looks alright ping 192.168.3.208 ( the machine's ip ) works, as does ping anything else on the network - the local net is 192.168.3.x I am running 2.2.2 kernel on hamm P Asokan
