Dear All, My network config. as follows. m/c A - 192.168.100.100 (eri0) m/c B - 192.168.100.200 (eri0) 172.16.80.5 (eri1) m/c C - 172.16.80.150 m/c A & m/c B in one LAN. Also m/c B & m/c C in another LAN. (i.e. m/c B has 2 eth ports) I need to connect (telnet/ftp etc) to m/c C from m/c A. How do I do the routing configuration ?? Thanks for your help. Regards, Nish.

create the file /etc/hostname.eri0 with a single line "h1" or anything in the file, create another file /etc/hostname.eri1 with a single line like "h2" or anything. add h1 and h2 on two seprate lines in /etc/inet/hosts file with the sepecified ip address for each interface.one of them must be of network 192.168.100 and other for 172.x add appropriate netmasks in the file /etc/netmasks. touch /etc/defaultroute and leave it empty. create file /etc/defaultdomain with your domain name on the single line of the file. try ndd -get /dev/ip ip_forwarding if out put is "0" then enable it.restart the system. hope it will work file. good luck
