My most important, reusable projects
Sorry. english translation is currently ongoing.
You have to live with the german one for the moment.
Projects listed here are GPL-Projects.
Thus you can aquire a personal copy with minimum financial efforts
(incl. sources, without any licencing limitations).
I can easily make individual modifications.
Cost/profit-relation is hardly to surpass.
Backward chronological.

R-TuX:
Is a project, financed by three employers.
It is my own, single-floppy-based TDSL-Router-Firewall-Linux-System,
which automatically installs from the Net (central software-maintenance).
With only one single Floppy, one can build a full-functional T-DSL-Router.
You only need an 486er, 2 NICs, at least 24 MB RAM.
Only the file pap-secrets (login-data) must be modified.
Because of the FAT32-Filesystem, this can be managed with every PC.
After Startup, those Firewalls can be administered remotely with ssh (public key).
With fwbuilder this can be comfortably done in a pool.
Future Features include booting over the IntraNet, without Floppy and automatic ISDN-Fallback.
