== Strategy ==

The idea is that we have access through ssh to a machine in the same LAN as the server (z800 in the diagram above). We want to make the SPARC server think it's booting from this machine, while we're in fact using ssh port forwarding to forward inbound connection to that machine to our VM.

== Instructions ==

Install Solaris 11 (amd64) in VMware, on laptop. 

Set-up SPARC AI server:
 vm# pfexec installadm create-service -a sparc

Make a client-specific AI config:
 cp /etc/netboot/{system,webboot}.conf /etc/netboot/cl.ie.nt.ip 
Edit <code>/etc/netboot/client-ip/webboot.conf</code> to reference client (e.g. behind NAT) IPs.

Set-up remote port forwarding:
 laptop$ ssh -S none -NT -R 5555:172.16.24.128:5555 -L 8080:192.168.0.1:80 vienna.mgk.ro

Set-up SPARC machine to netboot using static IP:
 ok setenv network-boot-arguments host-ip=192.168.0.60,router-ip=192.168.0.1,subnet-mask=255.255.255.0,file=http://192.168.0.100:5555/cgi-bin/wanboot-cgi
 ok boot net
