# Remote Access

The CSL employs a remote access functionality called **Remote Access Servers** (RASes for short) for students and staff to access their CSL files outside school grounds. Currently, we have two remote access servers (`ras1` and `ras2`) which are both VMs that are the only machines beyond a select few that provide incoming SSH from outside the CSL network.

We use [fail2ban](https://github.com/fail2ban/fail2ban), an intrusion detection software, to block repeated mass authentication attempts against the remote access servers.

Issues related to the Remote Access Servers should be directed to the [Infrastructure Lead](/general/sysadmins-list.md#current-leads).
