ssh -J bastion.astron.nl regtest@dop349.astron.nl
You won't be asked for a (bastion) password. The certificate you've just generated will last for twelve hours. Once it's elapsed, the only step from the above you need to perform again is

$ step ssh login example@email.com --provisioner "keycloak"

alias mystep='step ssh login example@email.com --provisioner "keycloak"'

Whereupon you'll be good for another twelve hours. The above command is a great candidate for a shell alias.

* Screen to run a terminal session without ssh connection
*******************************************************************************

https://linuxize.com/post/how-to-use-linux-screen/

screen --version

Basic Linux Screen Usage

On the command prompt, type screen.
Run the desired program.
Use the key sequence Ctrl-a + Ctrl-d to detach from the screen session.
Reattach to the screen session by typing screen -r.


To start a screen session, simply type screen in your console:

screen
screen -S session_name

This will open a screen session, create a new window, and start a shell in
that window. Now that you have opened a screen session, you can get a list of
commands by typing:

Ctrl+a ?

When you start a new screen session, it creates a single window with a shell
in it. You can have multiple windows inside a Screen session.
To create a new window with shell type Ctrl+a c, the first available number
from the range 0...9 will be assigned to it. Below are some most common
commands for managing Linux Screen Windows:

Ctrl+a c Create a new window (with shell)
Ctrl+a " List all window
Ctrl+a 0 Switch to window 0 (by number )
Ctrl+a A Rename the current window
Ctrl+a S Split current region horizontally into two regions
Ctrl+a | Split current region vertically into two regions
Ctrl+a tab Switch the input focus to the next region
Ctrl+a Ctrl+a Toggle between the current and previous region
Ctrl+a Q Close all regions but the current one
Ctrl+a X Close the current region

You can detach from the screen session at any time by typing:

Ctrl+a d

The program running in the screen session will continue to run after you detach
from the session. To resume your screen session use the following command:

screen -r

In case you have multiple screen sessions running on your machine, you will
need to append the screen session ID after the r switch.
To find the session ID list the current running screen sessions with:

screen -ls

There are screens on:
    10835.pts-0.linuxize-desktop   (Detached)
    10366.pts-0.linuxize-desktop   (Detached)
2 Sockets in /run/screens/S-linuxize.

If you want to restore screen 10835.pts-0, then type the following command:

screen -r 10835

When screen is started, it reads its configuration parameters from
/etc/screenrc and ~/.screenrc if the file is present. We can modify the default
Screen settings according to our preferences using the .screenrc file.
Here is a sample ~/.screenrc configuration with customized status line and few
 additional options:

~/.screenrc
# Turn off the welcome message
startup_message off

# Disable visual bell
vbell off

# Set scrollback buffer to 10000
defscrollback 10000

# Customize the status line
hardstatus alwayslastline
hardstatus string '%{= kG}[ %{G}%H %{g}][%= %{= kw}%?%-Lw%?%{r}(%{W}%n*%f%t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{B} %m-%d %{W}%c %{g}]'
Copy

* uex in screen lijkt eerst niet op te starten,
  matlab wel dus het ligt niet aan GUI, daarna lukts uex wel.
* :kooistra@dop386:~/git/hdl>  --> in gewone terminal
* ::kooistra@dop386:~/git/hdl> --> in screen terminal

* Quartus Qsys IP files in GIT
*******************************************************************************

1) Designs without QSYS: unb2b_arp_ping
Met meld blijkt dat de ip dir van unb2b_arp_ping en unb2b_minimal gelijk zijn
in de STAT-266 branch. Dat komt omdat je ze gecopieerd hebt en omdat
unb2b_arp_ping geen QSYS heeft zijn ze dus ongewijzigd.

Aangezien unb2b_arp_ping geen QSYS heeft, en ook niet zou krijgen, is het
beter om de unb2b_arp_ping/quartus/ip dir van unb2_arp_ping te deleten.

2) Designs with QSYS
Elk design op basis van unb2_minimal heeft zijn eigen QSYS ip files:

> ls $RADIOHDL_WORK/boards/uniboard2b/designs/unb2b_minimal/quartus/ip/qsys_unb2b_minimal

Als een design meer MM ports heeft dan heeft het ook meer ip files, bijv.
qsys_unb2b_heater_reg_heater.ip voor de unb2b_heater.

Het is kennelijk voor QSYS nodig om naast de .qsys file ook de ip/ files in de
repository te bewaren. Het is dus ook nodig om ze per design te bewaren, want
elk design heeft zijn eigen naam en extra MM slaves tov unb2b_minimal.

Echter het blijkt dat een nieuw design ook dezelfde ip/ files als unb2_minimal
mag gebruiken, dus zonder naamswijziging.

* Quartus version
*******************************************************************************

Quartus version meeting minutes 13 may 2020 (RW, LH JH, EK):

1) UniBoard2b IP is created using Quartus 18.0, same as used for ARTS SC3.

2) UniBoard2b synthesis is done with Q18.0 or newer. In case of a newer Quartus version we rely on Quartus to upgrade the Q18.0 IP for synthesis which works fine sofar. We also rely on that the Q18.0 models are still sufficiently correct.

2a) Jonathan uses Q19.4, because Q18.0 does not work remotely via ssh.
2b) Reinier uses Q19.2, because that is the latest version that support OpenCL without microprocesor.

3) UniBoard2c IP was created using Q19.4 by Jonathan, but we need to reconsider going to the latest Quartus version and recreate the IP, when we continue with the pinning and test designs for UniBoard2c

* Port forwarden:
Reinier gebruikte dop421 altijd als jumphost (of hoe het ook heet) en dan draai ik de scripts dus lokaal.

ssh -C -N -L 4840:10.99.0.250:4840 10.87.1.41 &
10.99.0.250:4840 is de raspberrypi waar de sdp translator op draait op poort 4840
10.87.1.41 is dop491
Op de PC waar je dit ssh commando uitvoert kun je je dan de sdp translator bereiken op (localhost, poort 4840)
De eerste 4840 in het commando mag ook een andere waarde hebben

Dan zonder --host
:kooistra@dop466:/dop466_0/kooistra/git/sdptr$ sdp_rw.py -r firmware_version

Helaas verwacht het SST script dat de data op de lokale machine aankomt, maar hetkomt op dop421 aan. Dus voor offload scripts werkt lokaal draaien zo niet.
