New users, Welcome!!!

Now you have got an account on the MIB system, you should make sure that everything works fine for you.

In here you will find information about how to log into our servers from MIB and outside MIB (home,...)

How to log in to the MIB system

We use the SSH protocol to login to our machines systems, the authentication relies on a global MIB authentication server.

service/protocol
ssh
host name
potato.wurnet.nl

Requirements

* You need to be on WUR network, either by using WUR VPN or by using the workstations in Helix building.

* Unix terminal, for windows putty or mobaXterm can do the job

* An account on the server Request an account

Using Windows

Several software can be used to make a ssh connection, we recommend to use MobaXterm as it comes with a friendly user interface. Follow this link to download MobaXterm. For this tutorial we use the portable version.

# Open MobaXterm
# Click on '''Start Local Terminal'''

# When the terminal opens, '''take the time to read the prompted message'''
# Log in to potato with the following command, (replace <your_username> with your username)
ssh <your_username>@potato

We recommend setting up ssh keys for more security, this is how to do so, (this step is Optional)

# Run the following commands one by one and make sure no error message is prompted
# The next command makes a folder, where the key will be created feel free to adapt it
mkdir -p //WURNET.NL/Homes/homa001/AppData2/mobaxterm/ssh/

# The next command creates ssh key files in the designated path 
# You will be asked to enter a passphrase which you will need everytime you log in using that key file.
# Be carefull as the passphrase does not replace your password
ssh-keygen -t rsa -b 4096 -f //WURNET.NL/Homes/homa001/AppData2/mobaxterm/ssh/potato.wur

# The next step is to copy the public file on the server so that it accepts your key, (replace <your_username> with your username)
ssh-copy-id -i //WURNET.NL/Homes/homa001/AppData2/mobaxterm/ssh/potato.wur <your_username>@potato

Create a new session to avoid typing the ssh command everytime, here is how to do it.

# On the top menu, click on the button '''Session''' to open the session settings
# Then choose '''SSH'''
# In the '''Basic SSH settings''' tab fill
# Remote Host: potato
# Tick the box '''Specify Username''' and replace all the text in the text box with your username

# Optional but recommended
# Then click on '''Bookmark settings'''
# Tick the box '''Customize Tab Color''' and select a uniq color for that session
# Set a suitable session name

# If you are using a private key
# Then click on '''Advanced SSH settings'''
# Tick the box '''Use private key''' and specify the path to your private key (//WURNET.NL/Homes/homa001/AppData2/mobaxterm/ssh/potato.wur)
# Click '''OK''' to save the session and try loging in

# If you log in using a ssh key you should see a similar prompt to '''Passphrase for OPENSSH private key'''
# Otherwise use your password

Using Mac OS

Make sure you have access to a terminal and install the software XQuartz to be able to open graphical windows. You need to set up the VPN to able to login outside WUR environment.

TO LOG IN

Enter the following command in a terminal to start the login process.

Replace <your_username> with the username you have chosen.

ssh <your_username>@potato.wurnet.nl

OR to enable X server,

ssh -Y <your_username>@potato.wurnet.nl

When connecting to the system for the first time, SSH will ask you to confirm your wish to login to the machine. Enter yes. Then you will be asked for a password every time you log in. We recommend setting up a ssh key to secure your connection the server, see below.

To change your password

After loging in use the command passwd to change your password.
