We are going to use FreeBSD/NetBSD/OpenBSD operating systems along with Linux to implement SEL Network Services.

Currently we have some of the services implemented on Linux:

Internet facing services:
- Mail Server (postfix) on CentOS 6
- IRC Server (unrealircd) on CentOS 6 - address: selroc.systems
- Forum Server (vBulletin) on Debian 10 - address https://www.selroc.systems

Internal services:
- The Foreman server (Debian 10)
- various FTP repositories (Debian 10)
