Compu-Global-Hyper-Mega-Net is CursedSilicon's "retro Internet" project, consisting largely of Windows XP era services.
Symlink is connected to the CGHMN and currently has the following services:
A spare Cisco 1760 router, accessible via Telnet only (with the password cisco). Poke around IOS 12.x, or telnet to other CGHMN hosts, or pad to public Telebahn hosts via X.25-over-TCP.
A server for the OpenText FirstClass 11.x collaboration platform (think SharePoint, except twice as dull).
There is a web interface available, but the primary interface to FirstClass is through the native desktop client (available for Windows/OSX/Linux). To register, either fill in the web form, or use the desktop client and log in as your desired username and password. Don't forget to input the server address under "Advanced".
FirstClass is set up for SMTP email, but newly registered users aren't automatically added to the CGHMN group, and won't be able to receive mail at the correct domain (contact me to do it manually).
Services that might be available in the future: Lotus Notes/Domino; Windows 2000 Terminal Server.
