Configuring the cpu server for plan 9
First add your user to the adm group. See fossil-p9.
Afterwards, set your timezone, see timezone-p9.ms.
Next, make sure to configure your network information. See ndb-p9.ms.
Now, we prepare rc scripts that must run on system bootup:
term% mkdir /cfg/$sysname/
term% dircp /cfg/example /cfg/$sysname/
Now, we need to configure networking:
If you have static networking (eg, you have a virtual private server),
edit /cfg/$sysname/cpurc to uncomment this line:
ip/ipconfig -g your-gateway ether /net/ether0 your-ip-address your-subnet-mask
If you are using wifi and dynamic networking, you may need to add these lines:
bind -a '#l1' /net
echo 'key proto=wpapsk essid=ESSID !password='^`{cat /lib/wpa/ESSID} > /mnt/factotum/ctl
aux/wpa -2 -s 'ESSID' /net/ether1
ip/ipconfig ether /net/ether1
Replace ESSID and make sure to store the wifi password in /lib/wpa/ESSID.
For wifi on Raspberry Pi boards, see rpi-wifi-p9.
Note: You may also want to copy these lines to /cfg/$sysname/termrc and also to run the
command manually, because by default, plan 9 runs as a terminal service. It will not
run as a cpu service until the cpu kernel has been compiled as described below.
Note: You *must* run ip/ipconfig before running ndb/dns (and possibly other
network services). Otherwise, you might see errors like:
ndb/dns: can't read my ip address
term% auth/wrkey
bad authentication password
bad authentication id
bad authentication domain
authid: glenda
authdom: fork.inter9.org
auth password:
secstore password:
Make sure to configure the auth server, see auth-p9.ms.
Build the cpu kernel:
For x86:
cd /sys/src/9/pc
mk 'CONF=pccpuf'
term% 9fat:
term% cp /sys/src/9/pc/9pccpuf /n/9fat/
Add these lines to the beginning of /n/9fat/plan9.ini
[menu]
menuitem=cpu, Plan 9 CPU Kernel
menuitem=terminal, Plan 9 Terminal Kernel
menudefault=cpu, 10
[cpu]
bootfile=sdC0/!9fat!9pccpuf
[terminal]
bootfile=sdC0!9fat!9pcf
[common]
nobootprompt=local!#S/sdC0/fossil
Make sure to replace sdC0 with your actual disk.
Make sure also to delete the pre-existing line:
bootfile=sdC0!9fat!9pcf
For Raspberry Pi:
% cd /sys/src/9/bcm
% mk 'CONF=picpu'
% dossrv; mount /srv/dos /n/9fat /dev/sdM0/dos
% cp /sys/src/9/bcm/9picpu /n/9fat/
Edit config.txt so the [pi1] block reads as follows:
[pi1]
# Pi Zero W uses this entry, not [pi0]
kernel=9picpu
Edit cmdline.txt so it reads as follows:
readparts=1 nobootprompt=local console='0 b115200' ether1=type=4330 nvram='#S/sdM0/nvram'
Make sure cmdline.txt is only one single line!
(You may want to replace picpu with pi2cpu, pi4cpu)
Clear nvram and then set a new password:
term% echo garbage >/dev/sdC0/nvram
Remember to replace sdC0 with your actual hard disk. On Raspberry
Pi, replace sdC0 with sdM0:
% echo garbage >/dev/sdM0/nvram
Set the password:
term% auth/keyfs
Add the hostowner bootes to sys and adm groups:
term% con -Cl /srv/fscons
prompt: uname bootes bootes
prompt: uname sys +bootes
prompt: uname adm +bootes
prompt: fsys main
main: create /active/cron/bootes bootes bootes d775
main: create /active/sys/log/cron bootes bootes a664
Append these lines to the bottom of /lib/ndb/auth:
hostid=bootes
uid=!sys uid=!adm uid=*
You may need to reboot and login as hostowner (bootes) in order for
the next step to work.
If you do reboot, select 1 for Plan 9 CPU Kernel:
Plan 9 Startup Menu:
====================
1. Plan 9 CPU Kernel
2. Plan 9 Terminal Kernel
Selection[default==1 (10s timeout)]: 1
When prompted, fill in the following values:
authid: bootes
authdom: example.com
auth password:
secstore password:
Change the hostowner's password:
term% auth/keyfs
term% auth/changeuser bootes
If you are using 9front drawterm and want to connect in text-only mode
(no graphics) with the -G flag, you will need to edit $home/lib/profile
to remove calls to rio. Comment out line 31:
# exec rio
You can run the below command:
term% mv (/usr/$user/lib/)^(profile profile.bak)
term% sed '31s/^/#/' /usr/$user/lib/profile.bak > /usr/$user/lib/profile
Then afterwards, you will be able to connect with drawterm -G as
follow:
$ drawterm -u $USER -h $SYSNAME -G
