How to set up a crossover ethernet connection between two Sun Solaris machines:
- Connect both machines using a crossover ethernet cable.
- root@solaris-machine-1# ifconfig plumb
- root@solaris-machine-1# ifconfig netmask
- root@solaris-machine-1# ifconfig up
- On each machine, ping the other. If both are reported as being alive, you're golden.
It would look something like this on a live setup:
root@igg# ifconfig ce1 plumb
root@ook# ifconfig ce1 plumb
root@igg# ifconfig ce1 10.0.0.1 netmask 255.255.255.0
root@ook# ifconfig ce1 10.0.0.2 netmask 255.255.255.0
root@igg# ifconfig ce1 up
