You can, for instance, use the hostname keyword in the rules file:
hostname your_host1 begin-script1 profile2 finish_script1
hostname your_host2 begin-script2 profile2 finish_script2
or you can use the model keyword if you want to specify the jumpstart per hardware model:
model SUNW,Ultra-5_10 begin-U5_10 profile-U5_10 finish-U5_10
("uname -i" will return the "model" for a machine.)

as mentioned by akeh, this a method to specify which image to load on which machine.

If you want that a specific machine get it's code from a specific JS, you can define it in the /etc/bootparams file. IN this file is mentioned from which JS which kind of code is downloaded (root=..., install=..., ...)

I'm looking at it from a security point of view, i.e.

I have 1 development JS server and 1 production JS server and I want to ensure that other groups only build new clients from the production server unless I allow them to 'test' from the dev JS server.

So looking at the answers, I should lock down the rules file on the dev JS server and only allow specific machines to be added to the rules file.

Does that seem correct or is there a better way?

 

by: elfiePosted on 2000-11-22 at 08:02:59ID: 5505984

Just be sure that you don't have any 'ANY' rules inside.

Also keep track of systems that were added in the /etc/bootparams file with the 'add_install_client" that use your development server.

If you setup the bootparams file in NIS and distribute it, you can control this file from a central machine.

 

by: k.kidambiPosted on 2000-11-29 at 13:45:13ID: 5667088

The best way to tackle this is to add / remove entries in the /etc/bootparams file. and direct the clients to go to the respective server. if the client's entry is not in bootparams file. js server is not going to serve the client.


Thanks
