Download Linux Distribution from App Store
From the start menu, open the Microsoft Store and type “Windows Subsystem for Linux”.
From here you can install the Linux distribution that you want, it should say “Windows Subsystem for Linux” in the app description.
Open the WSL App and Install SSH
From the start menu, type the name of the Linux distribution and you can open the WSL terminal by clicking on the app icon.
If you are using a Debian based Linux distribution, use the following command in the WSL terminal to install SSH. If you are using a Linux distribution that doesn’t have the apt package manager, then use the package manager specific to your Linux distribution to install SSH if necessary.
sudo apt-get install ssh
Make and Configure SSH Keys on WSL
Move to your home directory, create your ssh folder, and move into the ssh folder. Create the config file, make sure it is not called config.txt.
cd ~
mkdir .ssh
cd .ssh
touch config
Update your ~/.ssh/config file to read the following. Note that all instances of <campusid> should be replaced with your GSU username.
host arctrdgndev101
hostname arctrdgndev101.rs.gsu.edu
user <campusid>
Host arclogin
HostName arclogin
User <campusid>
ForwardAgent yes
CertificateFile ~/.ssh/id_<campusid>-cert.pub
IdentityFile ~/.ssh/id_<campusid>
Now issue the following command to generate your key.
$ ssh-keygen -t ed25519 -f id_<campusid>
Next, type the following command to enable the ssh-agent service.
eval "$(ssh-agent)"
Type the following command to add your key.
ssh-add ~/.ssh/id_<campusid>
Go to https://elpis.rs.gsu.edu/, then go to the “Sign SSH Certificate” page. Here, paste the content of the public key and click “Sign Key”. If there is an error generating the certificate, please verify that you copied the public key contents correctly. Since WSL is a virtual machine and is isolated from your local files, copy the contents of the certificate onto the clipboard. Use vim or nano to create a new file called id_<campusid>-cert.pub and paste the contents of the certificate into here. Write and save the file.
Type the following command:
ssh arclogin
If you are connected to the GSU VPN, then use the following steps to ssh to the cluster.
Fix DNS Issues on WSL
Up to this point, if you’re working from the GSU network, it appears that SSH to the cluster in WSL works. If you want to SSH to the cluster from WSL while connected to the GSU VPN, there are some issues that prevent it. This wsl-vpnkit script can be used to run on the side to resolve DNS issues in WSL. This software should allow SSH while on the VPN to work. Follow the steps below.
Power shell settings
Find Windows power shell in you start menu and choose “open file in location”.
Open “properties” of Windows Power Shell.
Click “Advanced” options.
Check the box next to “Run as administrator” and Click “OK”.
Click “OK”.
Creating a shortcut to launch settings
Create a text file wsl_vpn.ps1 with the following text :
Write-Host "Script wsl_vpn.ps1 started."
Get-NetAdapter | Where-Object {$_.InterfaceDescription -Match "Cisco AnyConnect"} | Set-NetIPInterface -InterfaceMetric 4000
Get-NetIPInterface -InterfaceAlias "vEthernet (WSL)" | Set-NetIPInterface -InterfaceMetric 1
Write-Host "Script wsl_vpn.ps1 finished."
Create a new shortcut. In the “Type the location of the item” browse the directory of wsl_vpn.ps1.
Create a name of the shortcut wsl_vpn_shortcut.ps1 (or whatever you want).
Open “properties” of wsl_vpn_shortcut.ps1 Add the text
powershell.exe -NoExit -ExecutionPolicy Bypass -File
in the very beginning of field “Target” and Apply this change.
Click “Advanced” options.
Check the box next to “Run as administrator” and Click “OK”
Click “OK”
Put the file wsl_vpn_shortcut.ps1 in a convenient directory.
Login to cluster
To login cluster from wls from vpn you need:
a) run GSU vpn
b) run WSL
с) run wsl_vpn_shortcut.ps1
Check up
After these steps you will be able to ssh arclogin.
To check that you made steps 1-2 correct print in wls:
ping 8.8.8.8
Now at the WSL prompt, type ssh arclogin to verify that you can ssh to the cluster while connected to the GSU VPN.
