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. 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). This allows off-campus users to routing your network traffic through the campus, giving you a Royal Holloway network address, behaving exactly like it would if you were on campus and this allowing you quick access to restricted services, like library services, your Y: drive and evening access to the Linux servers.
- 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 **Linux**, Royal Holloway officially recommends using the GlobalProtect app on Linux to connect to their VPN, found on [this page](https://intranet.royalholloway.ac.uk/students/help-support/it-services/access-off-campus/vpn/vpn.aspx).
**That being said,** I would strongly encourage using the free and open source utility [GlobalProtect-openconnect](https://github.com/yuezk/GlobalProtect-openconnect) to connect instead. It is avaliable as an official package on all major Linux distributions, maintains a persistent installation and is more convenient as it provides a graphical user interface.

For Ubuntu and Mint, the installation instructions are as such:
```
sudo add-apt-repository ppa:yuezk/globalprotect-openconnect
sudo apt-get update
sudo apt-get install globalprotect-openconnect
```
For Arch Linux, simply install:
```
sudo pacman -S globalprotect-openconnect
```
After installed, run `gpclient` to start the UI then enter `student-vpn.royalholloway.ac.uk` as the portal address.
