Configuring a Standalone CPU Server
D1388694202
Astevie
#When configuring a Plan 9 network, the first machine to set up is a
#standalone CPU and authentication server. After you have this, you
#can go on to configure a file server and then boot terminals and
#other cpu servers from it.
#
#(Note that the same machine can act as both auth/cpu server and file
#server.)
#
#Start by installing the distribution as though creating a standalone
#terminal. Reboot the system, and log in as any user that is in group
#sys. To add a user to group sys see [adding a new user]. The user
#needs to be part of group sys in order to be able to edit the
#required system files. In the default installation, the user glenda
#will do.
#
#EDIT CPURC, CPURC.LOCAL
#
#The first step is to edit /rc/bin/cpurc*. To add machine-specific
#customisations,
#
#! cd /cfg; mkdir $sysname; dircp example $sysname
#
#and edit the files in /cfg/$sysname. You will find that
#/rc/bin/cpurc already contains most of the needed instructions but
#most of them have been commented out. See cpurc(8) for details.
#
#Note that cpurc for a specific $sysname host is executed right after
#the prompt setup in the /rc/bin/cpurc file that will execute on a
#CPU server once it is booted. The rest of /rc/bin/cpurc will execute
#after your customized cpurc is finished. This allows you to keep the
#common bits of CPU server setup common and any specifics in separate
#files per $sysname. Note that system-specific scripts are also run
#at the end of the cpurc. The sequence is: /rc/bin/cpurc >
#/cfg/$sysname/cpurc > /rc/bin/cpurc > /cfg/$sysname/cpustart.
#
#Individual $sysname bindings can be set in either plan9.ini in your
#9fat partition (more about that below), or in /lib/ndb/local by the
#particular machine's ethernet mac address.
#
#At the end of /rc/bin/cpurc.local, you may wish to bind any devices
#you'll need. 'cat /dev/drivers' will list the available devices. In
#this case we have m (mouse), i (draw), S (sd - disk), and t (uart -
#serial); if you get errors about /dev/realmode, include P in this
#list:
#
#! for (i in m i S t)
#! bind -a '#'^$i /dev >/dev/null >[2=1]
#
#Uncomment the invocation of ip/ipconfig in /cfg/$sysname/cpurc,
#specifying the appropriate numbers where necessary:
#
#! ip/ipconfig -g <gateway-addr> ether /net/ether0 <ip-addr> <ip-mask>
#
#For other network configurations see [network configuration].
#
#Uncomment the two lines indicated if you wish to be able to boot
#other systems from this server. Note that on home networks running
#an additional dhcp server may not be desirable.
#
#! #ip/dhcpd
#! #ip/tftpd
#
#Uncomment the two lines indicated in /rc/bin/cpurc to enable the
#authentication functions:
#
#! # auth/keyfs -wp -m /mnt/keys /adm/keys >/dev/null >[2=1]
#! # auth/cron >>/sys/log/cron >[2=1] &
#
#Add these lines to /cfg/$sysname/cpustart, the auth services should
#be run after auth/keyfs
#
#! aux/listen -q -t /rc/bin/service.auth -d /rc/bin/service tcp
#
#and run the commands
#
#! mv /rc/bin/service.auth/authsrv.tcp567 /rc/bin/service.auth/tcp567
#! mv /rc/bin/service/tcp567 /rc/bin/service/!tcp567
#
#to enable the auth services.
#
#The file names indicate the port and protocol, and the file itself
#contains the commands for starting a service. The authsrv. and !
#prefixes indicate disabled services; adding or removing the prefix
#disables or enables the service. The original /rc/bin/service/il566
#and /rc/bin/service/tcp567 services were proxy calls for the
#authentication services to be used by terminals. We don't need these
#on the authentication server, but you may on other cpu servers.
#
#Note: To export a fossil to other systems, add the following line to
#your fossil configuration using fossil/conf, or enter it via con
#/srv/fscons for a temporary listener. See [setting up fossil].
#
#! listen tcp!*!564
#
#Optionally, you may add logic from /rc/bin/termrc to
#/cfg/$sysname/cpustart to start rio on the server. In most cases,
#the next three lines will suffice:
#
#! aux/mouse $mouseport
#! aux/vga -l $vgasize
#! exec rio
#
#ADD A HOSTOWNER USER
#
#You can decide what name to give your cpu server owner. This is the
#user that all the cpu servers run as. We'll name the user 'bootes';
#it is recommended that you also choose 'bootes' as it will appear in
#the instructions frequently.
#
#Connect to the fossil console and add a user using the uname command
#explained in the fossilcons(8) man page, by convention the owner of
#cpu and fileservers is called 'bootes'
#
#! con /srv/fscons
#! prompt: uname bootes bootes
#! prompt: uname adm +bootes
#! prompt: uname sys +bootes
#! prompt: fsys main
#! main: create /active/cron/bootes bootes bootes d775
#! main: create /active/sys/log/cron bootes bootes a664
#
#Then set up keyfs and provide a password for this machine:
#! auth/keyfs
#
#NETWORK DATABASE
#
#Edit the contents of /lib/ndb to fit your network, as described in
#[Network configuration]. You may want to check that the following
#attributes are in the database:
#
# * auth=authserver - recommended
# * proto=il - (outdated unless you are using the il protocol)
# * cpu=authserver - if you wish 'authserver' to act as a CPU server
# * fs=authserver - if you wish to serve files from 'authserver'
# * ntp=ntpserver - if you wish to use NTP for timesync
# * bootf=/386/9boot - if you wish to boot terminals using the PXE
# Boot Loader
#
#It's a good idea to check that you got your network config right by
#trying:
#
#! ndb/ipquery ip <your-ip-address> auth
#! ndb/ipquery ip <your-ip-address> cpu
#! ndb/ipquery ip <your-ip-address> ntp
#
#A simple example for a combined cpu/auth server, the 192.168.1.100
#machine, could be:
#
#! ipnet=mynet ip=192.168.1.0 ipmask=255.255.255.0
#! auth=bouncer
#! cpu=cycles
#! dns=lookup
#! dnsdom=9fans.net
#!
#! authdom=9fans.net auth=bouncer
#!
#! ip=192.168.1.100 sys=bouncer dom=bouncer.9fans.net
#! ip=192.168.1.101 sys=cycles dom=cycles.9fans.net
#! ip=192.168.1.102 sys=lookup dom=lookup.9fans.net
#
#If you're not setting up a whole network and just want drawterm
#access to the combined cpu and auth server you're configuring,
#addding the single line
#
#! authdom=some.domain auth=cycles ip=your.ip sysname=cycles
#
#to /lib/ndb/local will suffice if you also add the line
#
#! sysname=cycles
#
#to plan9.ini. The authdom and sysname can be chosen arbitrarily.
#This same entry should be added to the ndb of other machines which
#wish to dial and auth to this machine's services.
#
#Note the authdom, it needs to be the same as configured in the nvram
#content described later on.
#
#Add the following two lines to /lib/ndb/auth to say that the cpu
#server owner is allowed to become any other user (given the
#appropriate credentials):
#
#! hostid=bootes
#! uid=!sys uid=!adm uid=*
#
#INSTALL A STANDALONE CPU/AUTH KERNEL
#
#You need to use a cpu/auth kernel, which is not hard to compile:
#
#! cd /sys/src/9/pc
#! mk 'CONF=pccpuf'
#
#See [compiling kernels] for further details. Once it is built,
#install the kernel to your 9fat:
#
#! 9fat:
#! cp /sys/src/9/pc/9pccpuf /n/9fat
#
#And edit /n/9fat/plan9.ini to say
#
#! bootfile=sdXX!9fat!9pccpuf
#
#where sdXX is the disk with the 9fat partition, eg., sdC0.
#
#it is recommended to include a menu in plan9.ini which will give you
#a choice of which kernel to boot. This is particularly useful if
#things don't go quite as planned, such as your CPU kernel not having
#all the drivers you needed.
#
#See 9load(8) for more information.
#
#Here is an example:
#
#! [menu]
#! menuitem=4e, Plan 9 Fourth Edition
#
#! [4e]
#! bootfile=sdC0!9fat!9pcf
#! bootfile=sdC0!9fat!9pccpuf
#
#by having a 9pcf in there I know I can boot into my other kernel in
#case something goes wrong.
#
#NVRAM DISK PARTITION
#
#To support the security features of the authentication server, a
#section of disk is required to simulate non-volatile ram (NVRAM).
#
#This partition should have been created by the installer, check for
#/dev/sdC0/nvram (or whatever is correct for your disk drive.)
#
#If this is missing you can create a sub-partition inside the Plan 9
#partition using disk/prep. The sub-partition should be called
#'nvram', eg:
#
#! disk/prep /dev/sdC0/plan9
#
#Adjust the above command to refer to your plan9 disk partition. Then
#you can delete the 'swap' sub-partition, and replace it with a swap
#partition that is 1 sector smaller than the original. In the free
#space, create a partition called 'nvram'. It only needs to be 1
#sector in size. Again, this should not be needed usually as the
#installer should have created the partition for you.
#
#Now you need to invalidate the nvram contents so that the checksum
#won't be correct when you next boot. This will force the cpu server
#to ask you for authentication information.
#
#! echo blahblahblah >/dev/sdC0/nvram
#
#REBOOT
#
#Reboot the machine. When it comes up, it should load the new kernel
#(or ask you to select a kernel if you created a boot menu) and then
#complain about the nvram checksum being incorrect.
#
#It will ask for an authid, authdom, secstore key, and password. The
#authid is the host owner name, usually 'bootes'. The authdom is a
#non-empty domain (e.g. moscvax.edu) of your choosing (for
#debugging), and the secstore key and password should be secret
#password of 8 characters or greater in length. Remember the
#password, you will need it again later when creating the 'bootes'
#user.
#
#AUTHENTICATION SERVER CONFIGURATION
#
#Firstly, you must set the password for bootes using auth(8) and the
#password you just entered during bootup:
#
#! auth/changeuser bootes
#
#Assign the password. You can ignore the Inferno/POP secret if you
#won't need it, it may be the same as the Plan 9 password. The other
#fields are optional.
#
#After this you can use auth/changeuser to create accounts for other
#users that will be allowed in the server. Remember to add them also
#the the file server; for details see [adding a new user]
#
#ADDITIONAL STEPS
#
#If you want to set up a Plan 9 file server, and boot your CPU/auth
#server from it, read also the page on [installing a Plan 9 file
#server]. (Note: this page is archaic. Any machine may act as a file
#server simply by setting the fossil configuration to listen on the
#standard 9fs service port.) We strongly recommend this, since it
#makes system administration easier. In particular, if you use the
#disk at the cpu server as a backup partition for your file server,
#you will stay calm after disasters.
#
#You probably want to set up email for your users, see [mail
#configuration].
#
#If you wish to make use of netkey(1) authentication in addition to
#p9sk1, you will need to also create entries in the securenet(8)
#database.
#
#! auth/keyfs -m /mnt/netkeys /adm/netkeys
#! auth/changeuser -n bootes
#
#Create passwords for bootes and other users and then add another
#line to cpurc adjacent to the other invocation of keyfs. This is an
#addition, not a replacement.
#
#! auth/keyfs -wp -m /mnt/netkeys /adm/netkeys >/dev/null >[2=1]
#
#SECSTORE
#
#Users can make use of server side encrypted storage with secstore(1)
#I've added auth/secstored to my /cfg/$sysname/cpurc
#
#Users are added via secuser, see secstore(8)
#
#NOTES
#
# * A netkey binary is available from
# [ftp://plan9.bell-labs.com/netkey/] .
# * If you want to access the cpu server from the internet and have a
# firewall, open up ports 567 for auth(8), 17010 for cpu(1) and port
# 17007 for import(4). Port 17013 is used to serve the pre 9p2000 cpu
# protocol, so is probably uneccessary in most environments. Secstore
# is on port 5356.

# 17007 for import(4). Port 17013 is used to serve the pre 9p2000 cpu
# protocol, so is probably uneccessary in most environments. Secstore
# is on port 5356.

#depending on how far through network setup you are.
