some easy questions

Good morning managers

I once know how to do these, now they have slipped my mind. Can someone =
please refresh my memory=20

system: sparc10 with solaris 2.5

1. how do you change the netmasks ? I have tried "ifconfig le0 =
255.255.255.0", but the output of "ifconfig le0" doesn't show the =
change. I have also tried to put it in the /etc/netmasks file. That =
also didn't seem to do it.

2. I believe on solaris 2.5, there is a security protection that would =
not allow root to rlogin to another station. If you try, it returns an =
error message something like "no console ...". How do you turn this off =
so that root can rlogin ?

Thank you much
