You can confirm the SSH key has been added by authenticating to the server. If it doesn't ask you for your password, it's all set!
### Accessing Linux server off-campus in the evening
The RHUL Linux machines aren't able to be accessed off-campus in the evening due to security reasons. To circumvent this, you can connect to the RHUL VPN by following [this guide](https://intranet.royalholloway.ac.uk/students/help-support/it-services/access-off-campus/vpn/vpn.aspx).
The RHUL Linux machines **aren't able to be accessed off-campus in the evening** due to security reasons. To circumvent this, you can **connect to the RHUL VPN** by following [this guide](https://intranet.royalholloway.ac.uk/students/help-support/it-services/access-off-campus/vpn/vpn.aspx). The following information in this section is copied verbatim from that guide.
On **Linux**, download and install [this file](http://intranet.royalholloway.ac.uk/it/programs/pangplinux-5.2.4-c14.tgz) to connect to the VPN.
On **Windows**, follow these instructions to download and install the VPN:
1. Open your web browser and visit [https://student-vpn.royalholloway.ac.uk](https://student-vpn.royalholloway.ac.uk/). Please note that you must use 'royalholloway' and not 'rhul'
2. Log in using your university username and password
3. Download and open the installer for your operating system
4. You will be guided through the process to install GlobalProtect. Leave all of the options as the default and complete the process with the installer wizard
5. Once GlobalProtect has been installed open the app
6. The app will ask you for a _Portal address._ Enter _student-vpn.royalholloway.ac.uk_ in the box and press _Connect_
7. You will be prompted to log in. You will need to use your university email address (username@live.rhul.ac.uk format, e.g. abcd123@live.rhul.ac.uk) to access the university’s virtual private network (VPN). Enter these details, and press _Sign In_
8. [Follow the instructions here to sign in with MFA.](https://intranet.royalholloway.ac.uk/students/help-support/it-services/multi-factor-authentication.aspx)
### Change resolution and display settings on NoMachine

### Change default shell on the terminal
On most Linux systems including the CIM servers, `bash` is used as the default shell. Normally you'd use the `chsh` command to do this, however this is locked down by CIM for security reasons.
You can bypass this by modifying your `~/.profile` then relogging in. For example to change the default shell to `zsh`:
```
export SHELL=/bin/zsh
exec /bin/zsh -l
```
### Adding new fonts on NoMachine
To add new fonts, for example for use on Visual Studio Code or Eclipse, you'll need to add the font (.ttf or .otf) to your `~/.local/share/fonts` directory. Then, run this command to refresh your font cache:
```
fc-cache -f -v
```
Restart the application and you should be good to go!
