- If there is not a "root" account on a level in the Netinfo structure, then
- that level can only be modified on the machine that serves it. To solve
- this problem, add a root user to the particular level you want to be able
- to change from clients (i.e, in your case, add a "root" user to the /
- domain). The root users in these domains can have different passwords if
- you like and can make for added security since you will have to supply a
- password to make any changes to that particular domain. This would me
- that if someone got root on your server, they would only be able to screw
- with the local netinfo domain on that server (unless all your root
- passwords in Netinfo are the same!)...

- #Here's the exact situation. Voyager is our two level NetInfo server, so
- it
- #serves / and /voyager. (It's a NeXTcube, this is all NeXTstep 3.0.)
- #Pioneer, a color station, serves /pioneer.
- #
- #Pioneer can not authenticate itself to / or /voyager. It just can't. At
- #first I thought it was some sort of trusted_networks glitch, but we don't
- use
- #trusted_networks. Then I thought it might've been a machine/IP
- #address/ethernet address mismatch, but all the relevant data seemed fine.
-
- I would suggest that you use trusted_networks. Otherwise anyone can snarf
- any of your netinfo data by using tags.
