from an ignite DVD or even the boot disk of an HP-UX system:
ifconfig sni0 192.168.1.50 netmask 255.255.255.0 up
route add default 192.168.1.1
to reuse IP on different interface, unload the tcpipv4 driver, find the driver handle first:
not sure how to print the routing table, if anyone knows please comment ('route print') does NOT work.
