The cpu/auth server is the first machine that should be installed when setting up a plan 9 network. A good overview of the process is available from the Bell-labs Plan9 Wiki page "configuring a standalone CPU server".
After doing a base install, the first thing to do is add the account of the cpu owner. Infomation on adding users be found in the Getting Started with plan 9 paper.
The first step is to turn of permission checking on the kfs file system:
add a line like
10002:bootes:bootesto /adm/users, run kfscmd user to read the user database back into kfs and then run
disk/kfscmd 'create /usr/bootes bootes bootes 775 d' disk/kfscmd 'create /mail/box/bootes bootes upas 775 d' disk/kfscmd 'create /mail/box/bootes/mbox bootes upas 622 al'to setup bootes's home directory and mail box.
Turn back on filesystem checking and sync (critical if you care about your files...) and halt the filesystem
disk/kfsmd user disk/kfscmd disallow disk/kfscmd sync disk/kfscmd halt
Now reboot the machine using ctrl-alt-del and login as bootes (note the window system will not start at this point) next run
/sys/lib/newuserto set up a profile and start the window system.
The next step is to setup networking by editing /rc/bin/cpurc and /lib/ndb/local as described in the Getting Started with plan 9 paper.
When making the network entries in /lib/ndb/local make sure to add dns= and auth= entries. Our /lib/ndb/local is here . Note we had to have a class B section in the ndb/local file since we have a class B address.
The next setup is to make a number of changes to /rc/bin/cpurc as outlined in the Getting Started with plan 9 paper. Including enabling dhcp and tftp for the booting of diskless clients. Our /rc/bin/cpurc is here . This also includes sections from termrc in order to run rio on the cpu/auth server.
generate ssh keys:
disk/kfscmd allow aux/ssh_genkey chgrp -u bootes /sys/lib/ssh/hostkey* disk/kfscmd disallow disk/kfscmd sync
Set up /lib/ndb/auth so that the cpu owner user is allowed to become any user
hostid=bootes uid=!sys uid=!adm uid=*
setup authenication services:
disk/kfscmd allow rm /rc/bin/service/il566 rm /rc/bin/service/tcp567 cd /rc/bin/service.auth mv authserv.il566 il566 mv authserv.tcp567 tcp567 disk/kfscmd disallow disk/kfscmd sync
Build and install a cpu server kernel. We made modifications to the default pccpudisk file to support more hardware. (requires latest plan9 updates?) Our pccpudisk file is here .
disk/kfscmd allow cd /sys/src/9/pc mk 'CONF=pccpudisk' 9pccpudisk 9fat: cp 9pccpudisk /n/9fat/9pccpud disk/kfscmd disallow disk/kfscmd sync
modify the bootfile line in /n/9fat/plan9.ini to point to the new kernel. Our plan9.ini is:
bootfile=sd00!9fat!9pccpud bootdisk=local!#S/sd00/fs distname=plan9 partition=new scsi0=type=ncr53c8xx ether0=type=i82557 monitor=xga vgasize=1024x768x8 mouseport=ps2
create an nvram partition on the disk, we stole a sector from the end of the swap partition. Start disk/prep using
disk/prep /dev/sd00/plan9use "p" to print the partition table, we are interested in the swap partition, for us this starts as 16826587 and ends as 17767827 enter commands like:
d swap a swap 16826587 17767826 a nvram 17767826 17767827
invalidate the nvram using:
echo somegarbagehere > /dev/sd00/nvram
Reboot the machine, after the reboot it will ask for the passwd of the cpu owner user (bootes) and authentication id (bootes) and an authentication domain (acl.lanl.gov)
Now add some user accounts using auth/changeuser in particular and account for bootes. At this point the cpu/auth server should be all setup.
