Customizing the fileserver
The next step is to customize the fileserver, so we can boot cpu servers and terminals off of the fileserver.
First turn permission checking off on the fileserver so you can modify system files, reboot the machine and hit a key when you get the message about entering config mode, type "allow" followed by "end". Permission checking is now off and you can customize the fileserver. using the cpu/auth server, mount the fileserver filesystem on the cpu/auth server machine using commands like:
srv il!vampira mount -c /srv/il!vampira /n/vampiraand edit the files.
The fileserver will be used to boot 3 kinds of systems: terminals, secondary cpu servers, and the primary cpu/auth server.
A number of modifications are required to boot the cpu/auth server off of the file server.
copy configuration files from the kfs fisk filesystem to the fileserver
cp /n/vampira/rc/bin/cpurc /n/vampira/rc/bin/cpurc.orig cp /rc/bin/cpurc /n/vampira/rc/bin/ cp /n/vampira/lib/ndb/local /n/vampira/lib/ndb/local.orig cp /lib/ndb/local /n/vampira/lib/ndb/ cp /lib/ndb/external /n/vampira/lib/ndb/
boot the cpu server using the "il" option from the plan9.ini
after booting off fileserver, rebuild the os for 386, alpha, and arm
cd /sys/src mk clean mk install mk clean objtype=alpha mk install mk clean objtype=arm mk install
Very few modifications are needed to for booting terminals off of the file server. Cpu servers and terminals run different copies of some services. When setting up the cpu/auth server we just deleted the terminal services and replaced them by the appropriate cpu/auth server ones. For the general setup where multiple types of machine can boot off of the fileserver, we use multiple copies of the "service" directories. If you make separate copies of each of these directories, all you need to do is add your terminal to /lib/ndb/local. you will need the mac addr, which can be found in /net/ether0/addr.
At this point you should be able to boot a terminal by typing "il" at the boot prompt rather than "local"
Setup the /rc/bin/cpurc . file.
Set up /n/vampira/lib/ndb/auth so that the cpu owner user is allowed to become any user
hostid=bootes uid=!sys uid=!adm uid=*and setup the service directories:
mkdir /rc/bin/service.cpu cp /rc/bin/service/* /rc/bin/service.cpu/ mv /rc/bin/service.cpu/il566 /rc/bin/service.cpu/_il566 mv /rc/bin/service.cpu/tcp567 /rc/bin/service.cpu/_tcp567 mv /rc/bin/service.auth/il565 /rc/bin/service.auth/_il565
