12 == Start ==
13
14 Open the terminal (on Windows: Start, then cmd and press Enter). When the terminal window opens, type the following command (replace username with own name):
15
16 (% class="box" %)
17 (((
18 ##ssh username@dashy -p 8082##
19 )))
20
21 Now you will be asked for the password (this is Beethoven's password), enter the password.
22
23 When the password has been entered correctly, you can see that Beethoven is now logged in by (base) ##username@beethoven##. To start the Jupyter environment, enter the following command: ##my_jupyter.sh## and press Enter.
24
25 In the browser local on Safari or Chrome the following must now be entered:
26
27 [[url:http://116.203.106.242:8887/]]
28
29 The Jupyter environment will now open.
30
31 == First time access ==
32
33 If it is the first time to access this environment, a token must be entered at the top of the web page. The Token (a combination of numbers and/or letters) can be found in the Terminal here:
34
35 http://beethoven:8887/?Token=
36
37 You can copy the number (after ##Token=##) from the terminal and paste it at the top of the newly opened browser Jupyter page. Paste the number of the Token and press Log in or the Enter key.
38
39 The Jupyter environment will now be opened and ready for use.
40
41 == Shut down ==
42
43 To exit, you can manually close the browser.
44
45 In the terminal, use ##Ctrl+C## and you will see ##username@beethoven## again, after this you type ##"exit"## which will log you out of ##dashy##.
46
47 == Scripts ==
48
49 === Jupyter ===
50
51 This is the ##my_jupyter.sh## shell script used to start a Jupyter session. Every user has a slightly different one due to teh different port number. To let this script remain active even after you log out one can use ##screen##. Just start ##screen## and click through the initial message until you get a command prompt again. Then start the script and detach the session using the ##Ctrl-A D## key combination.

102 === Tensorman ===
103
104 Here's ##my_tensorman_plain.sh## which does not start ##jupyter##:
105
106 (% class="box" %)
107 {{{#!/bin/sh
108 cd $HOME/project
109 tensorman =jupyter-lab-gpu run -p 8889:8889 --gpu --python3 --name $USER bash
110 }}}
111
112 Here's the versioen that also starts ##jupyter## which usually is what we want:
113
114 (% class="box" %)
115 {{{#!/bin/sh
116 cd $HOME/project
117 tensorman =jupyter-lab-gpu run -p 8889:8889 --gpu --python3 --jupyter --name $USER bash
118 }}}
