OSX Netboot across subnets via RSA
Netboot and imaging OSX from same subnet as main K200 works just fine. At a separate location trying to image a few hundred machines, and none of them netboot. I've read here on ITNinja that netboot across different subnets isn't possible, and an RSA is needed.
I have an RSA already in place for Windows deployment, so I downloaded the K2000 Media Manager to my OSX machine at the remote site, and attempted to create a new netboot image directly to my RSA. It went through the whole process and errored out at the end saying permission denied. The RSA should be up-to-date, have the OSX image synced, and the main netboot image synced. I'm assuming creating a new netboot image directly to the RSA is what's needed, but it's not allowing me.
Any idea as to why it's not letting me create an RSA? I don't want to do all these sudo bless commands, since I have hundreds of iMacs to image - and supposedly an RSA should work.
