=== About ===

This is the tutorial for setting-up the 9front<sup>1</sup> operating system in a VPS slice on SDF. The tutorial is aimed at participants in the SDF [[:plan_9_9front#plan_9_boot_camp|Plan 9 Boot Camp]]<sup>3</sup>, but should be useful to other SDF VPS users. The //Boot Camp// participants will study virtualized //amd64 9front//. [[plan_9_9front#activities_of_the_sdf_plan_9_boot_camp_include|Previous activities of the SDF Plan 9 Boot Camp.]]

|x|An //amd64 9front// [[:vps_-_9front#sdf_boot_camp_9p_resource|complement]] to the SDF Plan 9 Boot Camp arrived in 2021.|

<sup>1</sup> [[http://fqa.9front.org/fqa1.html|Plan9front]] (or //9front//) is a fork of the //Plan 9// from [[ https://9p.io/plan9/index.html|Bell Labs operating system]]; [[wp>Plan_9_from_Bell_Labs#Derivatives_and_forks|Plan 9 Derivatives and forks]]. <sup>3</sup> [[wp>Booting|Booting]]

===== Getting Involved =====

SDF hosts the //plan9-l// mailing list for participants in the Plan 9 Boot Camp. Email '[[majordomo_on_sdf|majordomo]]' and 'subscribe plan9-l' to join.

Of the various VPS that SDF offers<sup>1</sup>, the SDF Plan 9 Boot Camp VPS is the only VPS provided without subscription, to SDF MetaARPA<sup>2</sup> members. The [[#plan_9_boot_camp|Boot Camp]] VPS slice includes cluster access to the SDF Plan 9 Community 9p server. With your help, Plan 9 participation at SDF can continue to promote networking, learning and participation. To request an SDF Boot Camp Plan 9 VPS, type '//plan9//' at the SDF shell<sup>3</sup> (''$ plan9'').

<sup>1</sup> [[https://sdf.org/?join|VPS]] membership, or [[https://sdf.org/?subscribe|participation]], required. <sup>2</sup> Type '//meta//' at the SDF shell (''$ meta'') for details. <sup>3</sup> [[https://sdf.org/|UNIX Shell Account]].

==== Console Menu and Shell ====

|x|**ctl-h** is backspace, kind of; **ctl-u** erases the current line. As seen, with the VPS Plan 9 console prompt **ctl-h** backspace, the screen output may not be what one would expect<sup>1</sup>.|
|x|To detach the Plan 9 console prompt (%), while retaining the ability to reattach it __without__ rebooting your server, press **ctl-]** to close the prompt (%). Then, press '**q**' to disconnect the VPS Maintenance Shell menu, and ssh connection. You can return again with another ssh to the allocated VPS server, an SDF VPS Maintenance Shell [[vps_-_9front#shutdown_and_restart|menu review]], and a press on the '**c**' key to connect to the Plan 9 console prompt (%).|

<sup>1</sup> [[http://sdf.org/?tutorials/Plan_9_rc|Control keys -- Available at the SDF Boot Camp VPS server console prompt]]

==== Getting started ====

|x|If you are reviewing this, and want to 9front Drawterm to the __new__ 9front Boot Camp VPS follow this suggested path.|
|x|__Install the 9front Drawterm, since it's needed for the 9front Boot Camp VPS.__|
|x|Write down your Plan 9 Boot Camp password (except for the Plan 9 Drawterm password).|
|x|Write down your Plan 9 Boot Camp IP address (YOUR_IP, as seen in the reminder below).|
|x|The VPS Maintenance Shell console __will ask for the password__ before confirming a shutdown '**s**', or a start '**r**'. //Keep your password nearby//.|
|x|Request [[vps_-_9front#sdf_boot_camp_communication_resources|assistance, encouragement, or help]].|

=== Reminder links ===

=== Install ===

After receiving notification of an allocated VPS slice, connect by '''$ ssh //<SDF member ID>//@//<VPS slice>//.sdf.org'''. The password<sup>1</sup> is the same as your SDF member login. At the VPS Maintenance Shell menu, type '**x**' for a //Clean Install//. 


<code>
  % WARNING! YOU WILL LOSE YOUR DATA!
  
  This function allows you to completely destroy your plan9 image
  and install a fresh generic distribution.
  
  Do you wish to continue? (yes/no) yes
</code>

<code>
  % Copying a fresh plan9 image [PLEASE WAIT]
</code>

|x|This may take time.|

<code>
 % Copying a fresh plan9 image [PLEASE WAIT] [COMPLETE]
 (continue)
</code>

|x|Press the '[**Enter**]' key to continue to the [[#shutdown_and_restart|VPS Maintenance Shell]].|

=== Basics ===

When the Plan 9 system boots, it will ask where root is from (the network, or a local disk). Just press the '[**Enter**]' key to select local (the default), "bootargs is (tcp, tls, il, local!device)[**local!/dev/sdC0/fscache**]". Next, there will be prompt to login. Press the '[**Enter**]' key to login as the Plan 9 default "user[**glenda**]:".

<code>
  bootargs is (tcp, tls, il, local!device)[local!/dev/sdC0/fscache]
  user[glenda]:
</code>

You will now see the Plan 9 VPS console rc prompt (%), Plan 9's shell.

=== Plan 9 shell ===

|x|**ctl-h** is backspace, kind of; **ctl-u** erases the current line. As seen, with the VPS Plan 9 console prompt **ctl-h** backspace, the screen output may not be what one would expect.|
|x|To detach the Plan 9 console prompt (%), while retaining the ability to reattach it __without__ rebooting your server, press **ctl-]** to close the prompt (%). Then, press '**q**' to disconnect the VPS Maintenance Shell menu, and ssh connection. You can return again with another [[#install|ssh]] to the allocated VPS server, an SDF VPS Maintenance Shell menu review, and a press on the '**c**' key to connect to the Plan 9 console prompt (%).|

|Plan 9 Rc shell|[[#tutorials|Plan 9 Rc Survival Guide]]|

<sup>1</sup> A VPS password change option is available from the VPS Maintenance Shell, after login.
==== Networking ====

|x|Review the ''/usr/glenda/start'' file, or rc script, from the VPS console prompt (%).|

<code>
  term% cat /usr/glenda/start
</code>

The mentioned ''/usr/glenda/start'' file does __not__ require editing. Any edit<sup>1</sup> can be made with ''% ed'', or ''% sam -d'', from the VPS console prompt (%), or later with ''% ed'', ''% sam'', or ''% acme'', from the Drawterm rio rc prompt (%).

|x|This [[#shutdown_and_restart|shutdown and restart]] section applies, and is __necessary__<sup>2</sup> after an ''% fshalt'', __before__ the networking is restarted.|

<sup>1</sup> ''% man dp9ik'' <sup>2</sup> ''% fshalt'' from an rc prompt (%), then at the "VPS Maintenance Shell" enter '**s**' - force shutdown, then enter '**r**' - reset or start.

===== 9front Drawterm =====

[[plan9front_-_drawterm_rio_and_stats|Drawterm]]<sup>1</sup> is essentially a BLIT terminal emulator which allows you to connect to your 9front system and load the //rio// windowing system. rio is a direct successor of UNIX 'layers' and Plan 9 '8½'. 

<code>
  $ ./drawterm -a YOUR_IP -h YOUR_IP -u glenda
</code>

=== From the 9front Drawterm screen ===

|1|Press [**Enter**] once.|
|2|Type your Drawterm password, then press [**Enter**].|

^Plan 9 Console^ Keyboard activity^
|**auth[your.IP.exhibt.here]:**| <= Press [**Enter**] once.|
|**glenda@plan9 dp9ik password:**| <= Type your **Drawterm password**, then press [**Enter**]|

|     The //**cpu: failed to chdir to**// message is not uncommon.     |

=== From rio: ===

^   New   ^ <= release the button here^
|   Resize   |	|
|   Move   |	|
|   Delete   |	|
|   Hide   |	|

|1|At the rio grey screen, press the right button of your mouse. A menu (above) should appear. Then, release the button over the "New" option.|
|2|Now, press the right button again near the upper-left corner of Drawterm, and drag the mouse to the lower-right before releasing the button, drawing a rectangle.|

|   New   |	|
|   Resize   |	|
|   Move   |	|
^   Delete   ^<= delete a window gracefully^
|   Hide   |	|

|There is a "Delete" option in addition to the "New" option. This "Delete" option is useful. It will delete a window gracefully.|

|   New   |	|
|   Resize   |	|
|   Move   |	|
|   Delete   |	|
^   Hide   ^<= hide a window^

|There is a “Hide” option in addition to the “New” option.|

==== Drawterm and file transfer ====

=== A 9front Drawterm note: ===

^Command^ 9front Drawterm output^
|''$ ./drawterm <nowiki>--</nowiki>help''|''usage: drawterm [-GBO] [**-h** host] [**-u** user] [-a authserver] [-s secstore] [-e 'crypt hash'] [-k keypattern] [-p] [-t timeout] [-r root] [-g geometry] [-c cmd <nowiki>...</nowiki>]''|

|Although __missing__ from the "''$ ./drawterm <nowiki>--</nowiki>help''" output, the "-r /path/to/local/directory" option will show the "/path/to/local/directory" files in "/mnt/term". This means that you can transfer files between the computer that you are connecting from and your 9front VPS simply by copying files in /mnt/term and getting them from your computer (or the reverse.)|
|**Example:** ''$ ./drawterm -a YOUR_IP -h YOUR_IP -u glenda -r /path/to/local/directory''|

<code>
[/path/to/local/directory]
[/path/to/local/directory] mdkir foobar
</code>

<code>
cpu% cd /mnt/term/foobar
cpu% pwd
/mnt/term/foobar
cpu% touch screenshot.challenge.txt
</code>

==== Closing Drawterm ====

|1.3. **Leaving the system**; Page 6.|
|//To leave your terminal you have all you need. Press the terminal power button (don’t look at the window system for it) and switch it off. Because the files are kept in the file server, any file you changed is already kept safe in the file server. Your terminal has nothing to save. You can switch it off at any time.//|

=== local os: ===

^Drawterm^ application^
|Quit|<= select quit|
==== Install or Build Drawterm ====

=== Binary Executables ===
Pre compiled Drawterm executables can be downloaded from the following links:
  * https://9p.sdf.org/drawterm **(OS X, Debian, Win 10)**
  * http://drawterm.9front.org/drawterm.exe **(Windows)**

=== Building from Source (Linux and UNIX) ===
If you have "git" installed, you can grab a copy by running something like the following in a terminal.

''git clone git:<nowiki>//</nowiki>git.9front.org/plan9front/drawterm''

Otherwise you will need to download the source. You can go to http://git.9front.org/plan9front/drawterm/HEAD/info.html, click the "files" link, and click the "snap.tar.gz" link to get a tarball of the latest snapshot. "tar xzf" the file and rename the new directory "drawterm".

You will also need compilers to build the source. If you are running a Debian or Ubuntu based system (and you've never built an application on your system), you can install these by running a command like the following:

''sudo apt-get install build-essential''

In addition to downloading the source code, you will need a couple of additional dependancies; libx11-dev and libxt-dev. If you are running a Debian or Ubuntu based system, you can install these by running a command like the following:

''sudo apt-get install libx11-dev libxt-dev''

Finally, we will need to build drawterm. If you are running Linux, you would cd into the drawterm directory and run the following:

''CONF=unix make''

After the process completes, you shouldn't see any error. There should now be a "drawterm" executable in the drawterm directory. You can test it by running:

''./drawterm''

If it runs fine, you should see a new window labeled "Plan 9 Console", with a prompt for the "cpu" (server).


===== A 9front rcpu application =====

From the plan9front Raspberry Pi rio rc terminal prompt (%):

=== Edit the /lib/ndb/local file: ===

|x|The ''echo 'auth=9p.sdf.org authdom=9sdf' <nowiki>>></nowiki> /lib/ndb/local'' is __only__ applied initially. The results are retained.|
<code>
% echo 'auth=9p.sdf.org authdom=9sdf' >> /lib/ndb/local
</code>

=== Check if factotum is running: ===

<code>
term% ps | grep factotum
glenda          130    0:00   0:00      168K Pread    factotum
</code>

|x|Start factotum if it is __not__ running.| 

<code>
term% auth/factotum
</code>

=== RCPU to 9p.sdf.org ===

|x|A ''9p.sdf.org'' user name (''-u USER'') is required.|

<code>
% rcpu -h 9p.sdf.org -u USER
password:
!
</code>

|x|Once connected to //9p.sdf.org//:|
<code>
cpu% cd $home
</code>

|x|Start the rio<sup>1</sup><sup>,</sup><sup>2</sup> window system:|
<code>
cpu% rio
</code>

|x|Start ''[[:vps_-_9front#command_reminder|stats -lmisce]]'' in a new rio<sup>1</sup><sup>,</sup><sup>2</sup> rc window:|
<code>
cpu% stats -lmisce
</code>

=== An incorrect password repair example: ===

<code>
% cat /mnt/factotum/ctl
key proto=dp9ik dom=9sdf user=USER !password?
% echo 'delkey proto=dp9ik dom=9sdf user=USER' > /mnt/factotum/ctl
%
</code>

===== 9front VPS update tasks =====

|x|'sysupdate' is reserved<sup>1</sup> for the user glenda (Thu Jan 14 08:07:38 GMT 2021).|
|x|The VPS Maintenance Shell console __will ask for the password__ before confirming a shutdown [**s**], or a start [**r**]. //Keep your password nearby//.|
|x|Step "II.) Updating your system" (''% mk install'') will take time.|
|x|Optionally,[[vps_-_9front#working_in_9front| select “scroll” to toggle the window scroll (on)]]. This will reduce the need to manually scroll during the install.|

<file config /plan9-l/Have_fun/there_is_a_lot_we_can_do_now/>

Tasks I., and II., are preformed from the 9front Drawterm VPS connection,
or 9front Drawterm rio rc prompt (%).

Task III. is preformed from the 9front VPS Maintenance Shell console rc prompt (%).
   a.) Due to the way that namespaces work on 9front, change
       to the console prompt to preform the "9fs 9fat" in Task IV.
   b.) be careful

I.) Updating your system:

1. type 'sysupdate' - note if changes are brought in.
   (you can 'cat /bin/sysupdate' to see how it works)
   (also just an 'hg incoming' will tell you what patches are available)
2. cd /
3. . /sys/lib/rootstub      (you can 'cat /sys/lib/rootstub' to see)
4. cd /sys/src
5. mk install

II.) Updating your kernel:

1. cd /sys/src/9/pc64
2. mk

III.) Installing your new kernel:

From the vps?.sdf.org console:

1. type '9fs 9fat'
# be careful:
2. cp /sys/src/9/pc64/9pc64 /n/9fat/9pc64
3. fshalt
4. select menu option 's' and then 'r'

OR, from the Drawterm rio rc prompt:

1. % cd
2. % pwd
/usr/glenda
3. % bind -a '#S' /dev
4. % 9fs 9fat
5. % cp /sys/src/9/pc64/9pc64 /n/9fat/9pc64
6. % echo sync >>/srv/hjfs.cmd
7. % fshalt
8. Select menu option 's' and then 'r' from the vps?.sdf.org console.

IV.) Your system should boot completely up-to-date.

=== clean or nuke: ===

|x|clean - The ''clean'' target removes object files and //yacc// intermediate files but does not touch the library. The ''nuke'' target removes the library as well as the files removed by the ''clean'' target.<sup>2</sup>|
|x|nuke - The ''nuke'' target removes the library as well as the files removed by the ''clean'' target.<sup>2</sup>|

If you have done a 'sysupdate' and have issues with mk install failing, try this.

===== Working in 9front =====

When using Drawterm<sup>1</sup> to connect to the SDF 9front cpu server, your local files will be available at "/mnt/term": "''% lc /mnt/term''". You can copy files between the SDF 9front VPS and your local os without the use of additional protocols. In other words, when working with Drawterm, your environment is a composite of your local os and the Plan 9 system -- technically it is a three node grid, because the Drawterm program acts as an ultra-minimal independent Plan 9 terminal system, connecting your host os to the SDF 9front cpu server.

==== Adding a User ====

|x|'[[#front_vps_update_tasks|sysupdate]]' is reserved for the user glenda (Thu Jan 14 08:07:38 GMT 2021).|

^ Section^ FQA 7 - System Management^
|7.3.1 - Adding users|http://fqa.9front.org/fqa7.html|
|7.4.2 - Adding users|http://fqa.9front.org/fqa7.html|

You may want to add a user to your system once you get the hang of things. There is really //no need to create a new user// when you are first starting out. It's safer to use the Drawterm rio rc prompt (%) for the following task, should there be a need for the '[Backspace]' key.

To create a new user, you must connect to the file server console by typing: '''con -C /srv/cwfs.cmd'''<sup>1</sup>. Once at the file server prompt (''a blank''), create a new user. Replace USER with what you want your new user to be named: 'newuser USER'. You will need to add that USER to the "sys" group if you want it to be able to change system configuration files. Again, change USER to what your new user name is: 'newuser sys +USER'. Exit the file server console prompt (''a blank'') by typing: '**ctrl+\**'. You will now be at the "''> > >''" prompt; type '**q**' to quit the "''> > >''" prompt.

<code>
  % con -C /srv/cwfs.cmd
  newuser USER
  newuser sys +USER
  newuser adm +USER
  newuser upas +USER
  
</code>

''Ctrl+\''

<code>
  >>> q
  %
</code>

The following steps assume that you have [[:plan9front_-_acme_sam_abaco_mothra_and_man|edited]] files while user "glenda", have run '[[#shutdown_and_restart|% fshalt]]' from the [[#shutdown_and_restart|VPS console]] rc prompt (%) or Drawterm rio rc prompt (%), been able to "[[#shutdown_and_restart|[s] - Force Shutdown]]" and "[[#shutdown_and_restart|[r] - reset or start]]" the VM from the VPS Maintenance Shell, and have used 9front Drawterm successfully. Enter the new "USER" name after an '**fshalt**' and a VPS Maintenance Shell [**s**] - //Force Shutdown// and [**r**] - //reset or start//.

''user[glenda]:'' <- Enter the new 'USER' name.

Verify your new "[[#adding_a_user|USER]]" login with '''pwd''' or '''lc -l'''. __**Stop**__ if '''pwd''' does not show your new "USER" name. 

Initialize the new user environment with '''% /sys/lib/newuser''', before '''% mail -c''', from the VPS console prompt (%).

<code>
  term% /sys/lib/newuser
</code>

<code>
  term% mail -c
</code>

A list of eight directory and file tasks.<sup>2</sup>

<file config /plan9-l/Have_fun/add_an_unnecessary_user/>
mkdir /n/other/usr/$user

cp -x /usr/glenda/sdf /usr/$user/sdf
cp -x /usr/glenda/start /usr/$user/start
cp -x /usr/glenda/bin/rc/riostart /usr/$user/bin/rc/riostart
cp /usr/glenda/lib/profile /usr/$user/lib/profile
mkdir /usr/$user/www
cp /usr/glenda/www/* /usr/$user/www/
</file>

A list of one pending task.<sup>3</sup>

<file config /plan9-l/Have_fun/pending_task/>

bind -c /n/other/usr/$user/tmp /usr/$user/tmp

</file>

A list of two optional tasks.

<file config /plan9-l/Have_fun/optional_tasks/>

mkdir /usr/$user/lib/mothra
cp /usr/glenda/lib/mothra/hit.html /usr/$user/lib/mothra/hit.html

</file>

The mentioned eight tasks are preformed from the VPS console prompt (%).

<code>
  term% mkdir /n/other/usr/$user
  term% mkdir /n/other/usr/$user/tmp
  term% cp -x /usr/glenda/sdf /usr/$user/sdf
  term% cp -x /usr/glenda/start /usr/$user/start
  term% cp -x /usr/glenda/bin/rc/riostart /usr/$user/bin/rc/riostart
  term% cp /usr/glenda/lib/profile /usr/$user/lib/profile
  term% mkdir /usr/$user/www
  term% cp /usr/glenda/www/* /usr/$user/www/
</code>

A VPS console prompt (%) ''% sam -d'' edit example, similar to ''% ed''. Optionally, a new user start file can be created while user glenda is connected with Drawterm, before a new user is created. The ed, sam, and acme editors are usable with a Drawterm rio rc prompt (%).

<file config /plan9-l/Have_fun/edit_start/>

</file>

Start Drawterm from the local operating system, after the ''/usr/$user/start'' user name is changed, and the ''/usr/$user/start'' www directory name is changed.

<code>
  $ ./drawterm -a YOUR_IP -h YOUR_IP -u new USER
</code>

<sup>1</sup> For the cwfs file server, only ([[#shutdown_and_restart|"halting.../srv/cwfs.cmd..."]]). <sup>2</sup> [[http://fqa.9front.org/fqa7.html|7.3.1 - Adding users]] //New users are created without a profile, <del>mail directory</del>, tmp directory (needed to edit files with sam) or other confections// (sdf, start, riostart, www, index.html). <sup>3</sup> [[http://fqa.9front.org/fqa7.html|7.3.1 - Adding users]] //The default system /lib/namespace does the [[#ns:|following]]: bind -c /n/other/usr/$user/tmp /usr/$user/tmp//

==== Configure a Time zone ====

^ Section^ FQA 4 - 9front Installation Guide^
|4.3.15 - tzsetup|http://fqa.9front.org/fqa4.html|
^ Section^ FQA 7 - System Management^
|7.6.3 - UTC Timesync|http://fqa.9front.org/fqa7.html|

You might want to configure your system's timezone<sup>1</sup>. Identify the timezone with '''% lc /adm/timezone'''. Assuming that the CET time zone is appropriate, login as the user <del>'adm'</del><sup>2</sup> 'glenda' and 'cp /adm/timezone/CET /adm/timezone/local'. Last, while user "glenda" edit the "TIMESYNCARGS" line in the "/rc/bin/termrc" <del>(or "/rc/bin/cpurc")</del>, using an NTP service. Set it to  "TIMESYNCARGS=(-n pool.ntp.org)" and [[#shutdown_and_restart|reboot]]<sup>3</sup>. 

''user[glenda]:''

<code>
  % lc /adm/timezone
</code>

<code>
  % cp /adm/timezone/CET /adm/timezone/local
</code>

<code>
% sed 4q /rc/bin/termrc
#!/bin/rc
# this file is run if service=terminal
#TIMESYNCARGS=(-rLa1000000)
TIMESYNCARGS=(-n pool.ntp.org)
% 
</code>

<code>
  % sam /rc/bin/termrc
</code>

<code>
  % fshalt
</code>


=== Setting a User's Timezone ===

If you just want to change the timezone of your user account on a shared system, you can add something like the following to your lib/profile:

<code>
cat /adm/timezone/US_Central > /env/timezone
</code>

<sup>1</sup> [[https://9p.io/wiki/plan9/Installation_instructions/index.html|Plan 9 Wiki Installation Instructions]], //SETTING UP CORRECT TIMEZONE// section. <sup>2</sup> '''% cat /adm/users | grep adm''' <sup>3</sup> '''% fshalt''' from an rc prompt (%), then at the "VPS Maintenance Shell" enter '**s**' - force shutdown, then enter '**r**' - reset or start.

====== Plan 9 Boot Camp ======

SDF periodically runs a Plan 9 Boot Camp which is open to anyone with an SDF user<sup>1</sup> account. <del>Of the various VPS that SDF offers<sup>2</sup>, the SDF Plan 9 Boot Camp VPS is the only VPS provided without subscription, to SDF MetaARPA<sup>3</sup> members.</del> These Plan 9 Boot Camps are announced about 30 days before they begin and are often set around the //International Workshop on Plan 9// conference<sup>4</sup>. They are usually a seasonal occurrence and run for about 2 months.

|Why learn Plan 9 as a group?|
|Plan 9 wants a community.|
|Yes you can learn a lot on your own but Plan 9 was designed with a network of machines and users in mind.|

Activities of the SDF Plan 9 Boot Camp include:

|x|Installation or pre-generated Plan 9 instance under Xen|
|x|Self Guided Discoveries in: ed, network configuration|
|x|Self Guided Discoveries in: drawterm (from your computer), rio and stats|
|x|Self Guided Discoveries in: acme, sam, abaco, mothra and man|
|x|Self Guided Discoveries in: mapdemo, catclock, juggle and tetris|
|x|Self Guided Discoveries in: 9front and contrib via ftpfs|
|x|Self Guided Discoveries in: mailing list and faces|

During the SDF Plan 9 Boot Camp you are encouraged to make screenshots and videos of your Self Guided Discoveries and share your experiences on //plan9-l// to inspire others to do the same. Participants in the Plan 9 Boot Camps also get a contrib directory on ''<nowiki>ftp://ftp.sdf.org</nowiki>'' (in //pub/sdf/plan9/contrib//). This directory persists and can be used perpetually for Plan 9 related sharing.

|x|The [[:image_gallery|SDF Image Gallery]] wiki page offers a link to additional SDF [[:social_network|Social Networks]], for possible web based Boot Camp screenshot sharing.|

<sup>1</sup> [[https://sdf.org/|UNIX Shell Account]]. <del><sup>2</sup> VPS membership required. <sup>3</sup> Type "//meta//" at the SDF shell (''$ meta'') for details.</del> <sup>4</sup> International Workshop on Plan 9 http://iwp9.org/

^Some hints about Plan 9^
|Plan 9's system console is a TTY, not a VT|
|In UNIX almost everything is a file, in Plan 9 everything is a file|
|Plan 9 is more like UNIX than Linux is like UNIX|
|Environment variables are stored and manipulated in /env|
|System configuration is in /cfg|
|Login configuration is in /rc/bin (termrc or cpurc, also .local files)|
|System types: cpu vs. term|

<sup>1</sup> Dependent on schedule availability. <sup>2</sup> A snippet from Plan 9 ''% man srv'': [[http://9p.io/magic/man2html/4/srv|9fs:]] -- //9fs is an rc(1) script; examine it to see what local conventions apply.//

===== Conclusion or close =====

The wiki formatting used in this tutorial was reviewed with the SDF Plan 9 Boot Camp plan9front mothra browser, and the mothra option '-k': ''% mothra -k''. The intention was to support those SDF Plan 9 Boot Camp participants who may participate (in the Boot Camp) with a low-speed Internet connection. The outcome of the mentioned formatting decision is pending the approval of future wiki editors. Have fun.
