Instructions

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

Set-up SPARC AI server: 

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 /etc/netboot/client-ip/webboot.conf to reference client (e.g. behind NAT) IPs.

Set-up remote port forwarding: 

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: 

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 
boot net
