Ok, this is my preliminary homepage.

Installing and configuring Linux on a Thinkpad X40 Laptop,

I documented the configuration of my X40 laptop, since there is no such information on the net currently.

My description is to be found here.

Chroot all apps you want

The script http://www.chronox.de/chroot/chroot-0.1.tar.bz2 can be used to put any application in a chroot jail, removing any capabilities or let it run under a different user ID.
Tested with Squid, rinted, SSH, Portmapper.

Updated to version 0.1 on August 24 2002

It uses a helper program http://www.chronox.de/chroot/compartment-1.2.tar.bz2 which is an upgraded version of the SuSE compartment from Marc Heuse.

Here is the Changelog.

A sophisticated bandwidth control script with packet filter for Linux

Shaper is a traffic shaper and a packet filter for a server and for a gateway. With only limited configuration information, that are to be supplied, this script can control which and how information flow through the box.

Use this script with only a few configuration options to throttle certain data channels or to guarantee certain bandwidth for a connection. Additionally you can easily add packet filter rules with SYN/ACK checks and statefulness. The ruleset for the packet filter is being optimized to reduce time for unnecessary checks of an IP-packet.

The traffic shaper will only work with Linux kernels 2.4 and greater and is based on the iproute2 framework. Additionally the packet filter is based on netfilter with IPTables of the 2.4 kernel.

Updated to version 1.3 on August 24 2002
http://www.chronox.de/tc+filter/shaper-1.3.tar.bz2

And here is the Changelog.

Yes, and it is finally done: you can shape your bandwidth even on a box that is your masquerading gateway to the Internet! A local box behind the gateway, that downloads a lot, can be configured to download at a limited speed.

IF YOU USE VERSION 0.6, PLEASE UPDATE TO A CURRENT VERSION. Check Changelog for details.

If you experience a problem with Debian and the Ingress queue, please get the latest iproute2 package for woody or sid.
