The problem could be solved by RTFM - I looked in "Global Index" and
didn't find anything useful so I wrote to the list. Many thanks to :

for pointing me in the right direction. In the volume System and Network
Administration (SunOS 4.1) page 700 ff is all I need for SunOS 4.1.x
For Solaris 2.x I have to put entries in /etc/system. I include the mail
from Erwan Marec :
