Very Computer

I setup a JS install server (on one subnet) and on another subnet I
setup a boot server.
I use RARP/BOOTPARAMS for booting the client.

When JS client boots (boot net -v) it finds the boot server,
configures /dev and /devices says "using RPC bootparams ...", says
configured eri0 (the only network interface on client) and here it
dies.

I presume the JS client does not get the default root from the Boot
Server. The Boot Server has previously been hardened using JAAS. Does
anyone know what service (or lines in /etc/init.d/inetsvc ???) should
be started so that the JS client can find its way to the install
server and mount the OS image ??

I didn't find anywhere detailed information about how the default
route gets transfered from boot server to install server. Normally I
would not care "how exactly" it is done. But as you see I am forced
to.

Thank you.

Debugging Jumpstart is a time-consuming task.....but of course you want it
to work (been there....)
What makes you conclude it's the default route?? You don't tell whether it
worked before (before the JASS hardening)....
I'd try and snoop both subnets (with a bit of grepping you'd be able to see
what traffic goes between client, boot- and js-server.....
Lot's of JS-errors (non-visible) I ran into was NFS problems....this can be
recognized during snoops when client is re-requesting NFS-locations.....How
are your subnets separated?? By a router or firewall?? Are you sure you
allow the right traffic between them (firewall rules and router access
lists)??

Good luck!

However, that point of the boot process isn't likely to stall based on a
default route.  Snoop the wire for client packets and see what you get.
Are you getting any NFS transactions at the time?

I had earlier installed a JumpStart boot server on one workstation;
now I was trying to put the boot server on another one. And I forgot
to stop or restart the rpc.bootparamd server on the old boot server.
So now I had two rpc.bootparamd servers in the same network.

So practically, because I was sloppy last time when I played with JS
and did not clean up after it I had to pay the price now. It was
however a good oportunity to learn more about the process and play
with snoop.

I simply stopped rarpd, tftpd, bootparamd,  nfs server on the old boot
server and it all worked fine.

BTW: is there any script provided with Solaris to undo the config
modifications done by the add_install_client  script  ( to automate
what I did in the above steps ) ?

Vlad Grama.

This won't necessarily undo everything (for instance if you've
associated an IP address or MAC address with the host, it won't remove
the entries from /etc/hosts or /etc/ethers).
