The CSL's remote access servers
The Remote Access Servers (RASs for short) provide remote access functionality in the CSL. We have two remote access servers (
ras2) which are both VMs that are the only machines beyond a select few that provide incoming SSH from outside the CSL network. They allows TJHSST students and staff to access CSL resources from home.
We use fail2ban, an intrusion detection software, to block repeated mass authentication attempts against the remote access servers.
