Across is a collection of shell scripts for configuring server infrastructure, VPN services, and system utilities on Linux systems.
The project addresses several distinct server administration tasks through individual shell scripts. WireGuard.sh automates VPN server configuration and startup. BBR.sh installs the latest kernel with TCP BBR congestion control enabled. KMS.sh automatically deploys a KMS server for Windows activation. Bench.sh measures I/O performance and network speed. Backup.sh handles encrypted database and file backups with optional automatic transfer to Google Drive or FTP servers using AES-256-CBC encryption. Ftp_upload.sh manages file uploads to FTP servers. Unixbench.sh installs and runs the UnixBench performance testing suite. Each script requires configuration before execution where applicable.
This collection suits system administrators and server operators who need quick deployment of common server components and maintenance tasks. The scripts are most appropriate for Linux environments where shell scripting is the native administration language. The backup functionality is particularly useful for those running MySQL or MariaDB databases who want encrypted, automated backups with cloud or FTP transfer capabilities. Users should be aware that some scripts like L2TP and PPTP are marked as deprecated and should not be used.
The project shows ongoing maintenance with documentation links provided for each script. Development activity appears focused on keeping individual utilities functional rather than expanding the scope of the collection, as evidenced by the deprecation of older VPN protocols while WireGuard support remains current. The codebase remains relatively stable with scripts addressing established server administration needs.
