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.

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. **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.
