Linux Expo at Union Bank of Switzerland

During the summer of 1997, employees of the Union Bank of Switzerland (UBS) put on a one-month expo to showcase Linux. This article describes how and why we did it.

The Union Bank of Switzerland (UBS) is one of Switzerland's three largest banks, with offices world-wide and 30,000 employees. Currently, UBS has 25,000 PCs running mainly Windows 3.11, 800-900 Novell NetWare servers (3.11 or 4.11), around 800 applications servers, around 1,000 workstations running Solaris and at least 3,000 printers.

I work in the system development section (SYBS—System and Basic Services) where we mainly use workstations and servers running Solaris 2.5.1. We produce our own “repackaged” Solaris release, named OpenLAN, which is used on the production Unix servers. The OpenLAN release includes Perl, tcl/tk, et al.—the normal set of Unix tools in a package format. Notice the world “package” above. All software is delivered in a Solaris (Sys V) package for easy installation and removal.

Quite a few of the employees have a PC at home and for those working with or on the Unix side, it is (or would be) quite natural to install Linux at home. Linux provides an ideal environment for learning more about Unix in general, system administration and Unix tools. Also, a Linux system is neither resource hungry nor expensive to set up. Today it is possible to buy a shrink-wrapped installation on a CD-ROM, and you do not need to be technical expert to install Linux on your machine.

In the building where our section is located, there is an area which is used for one-month expositions about different subjects. The subjects range from information about different parts of UBS, security policies or employees' personal interests: astronomy, model plane flying, etc. The available area is approximately four by four meters with two panels for posters.

Last summer, Alois Camenzind thought that a small Linux expo would be a good idea. This would enable us to spread information about Linux and its uses—let others know that Linux is a “real” Unix system. After getting the “Okay”, Camenzind contacted employees within the section who had expressed both knowledge and interest in Linux. We formed an unofficial workgroup to prepare the Expo. The main work was producing posters with information about Linux and Linus Torvalds, getting resources (machines), setting up the machines and contacting interested companies for information and products.

We ended up with two Intel 486 Compaq boxes which were set up running Linux kernel version 2.0.12 (the latest stable release at that time). We used the Red Hat Rembrandt Beta II distribution provided to us by Red Hat. A SPARCstation 5, running kernel version 2.0.16 with the SPARC Red Hat distribution, was also on display to show multiple platform support.

We set up an Apache 1.1.1 WWW server running on of one of the Compaq machines. This WWW server had a preloaded cache with HTML pages from the SSC web site, http://sunsite.unc.edu/, the Swiss Linux User Group and other interesting Linux-related web sites. Since we were behind a firewall, we opted to load the cache on an Apache proxy server to make information generally available during the Expo.

The same machine also served as an NFS server for the smaller Compaq on which we stored the binaries and sources. The NFS server made it possible for interested people within UBS to obtain more information via HTTP or to mount the exported file system via NFS to get up-to-date kernel sources.

X11 was running on all machines, as well as a subset of the application packages provided in the distribution as an example of what kinds of software are included in a typical Linux distribution. To show an example of a commercial application running under Linux, we installed a demonstration copy of Applixware. We configured the machine to start Netscape whenever a user logged in, displaying our WWW server home page with pointers to the cached pages and other collected material. This was our invitation to the user to start browsing and discover more information about Linux.

Behind the machines (see photographs) were the panels with posters about Linux (all in German): “What is Linux?”, “Information sources for Linux”, “The GNU General Public License (GPL)”, “Linux Development History”, “Linux Time Line” and “Who is Linus Torvalds”. We also made information provided by SSC and Red Hat available beside the machines.

During display, anyone could just walk up to one of them and log in. Then (s)he could playing with the system, start X applications or just browse the local web via Netscape. We also provided a mirror of the latest release of the kernel as well as a Linux distribution which the user could copy.
