The Groupwise client for linux comes as an .rpm file, which installs into Suse and RedHat linux just fine, but not Debian. Here’s how to install Groupwise into Debian.
First, install the rpm package installer
apt-get install alien
Next, install the necessary files to run groupwise
apt-get install gcc
apt-get install libstdc++5
Next, install java from ww.java.com following the included directions
Finally, install groupwise
alien -i –scripts novell-groupwise-gwclient.i386.rpm
A Groupwise launcher should be on the desktop now or groupwise can be called directly from /opt/novellgroupwise

With the URLfilter addon installed, an IPcop firewall can be turned into a free content-filtering web gateway perfect for a church, non-profit organization or home office. Access to inappropriate sites whether they be pornagraphic or just not work-related will be denied automatically at the firewall. Both IPcop and URLfilter are free to download and use.
Why IPcop?
IPcop differs from most internet routers and firewalls because it has proxy software built-in. At first glance, a proxy server doesn’t do anything more than a standard router. Both will allow multiple computers inside the network to access websites on the internet, but a proxy servers looks at the actual web address in order to get a web page. For example, a standard router will recognize that a computer is visiting a website out on the internet whereas a proxy server understands that a computer is visiting www.MSN.com/music or www.msn.com/jobs. By looking at the full web address, IPcop can create internet access logs accurate down to the actual web page that was visited. IPcop and other free firewalls are compared in this article.
Another handy trick that IPcop can do is proxy web traffic transparently. Most proxy servers require users to make configuration changes to Internet Explorer or Firefox to use them, but that is not the case with IPcop. Web traffic can be proxied, logged and filtered without any configuration at the workstation and most users will never know that their web traffic is being analyzed. If a network administrator is just interested in keeping a detailed web access log, then IPcop can do that by? default. URL Filter adds the filtering capability.
Why URL filter?
URL filter (Short for Universal Resource Locater Filter) just adds a module to IPcop that helps it make decisions on whether to process a computer request for a web page. It makes decisions two ways. It keeps a list of known unacceptable websites and blocks those and it keeps a list of bad words and blocks anything with one of those bad words in the name. URL filter can be configured to download new lists of bad words and sites automatically.

I finally went to install 10.5 Leopard on my laptop and immediately ran into trouble. The install utility would not recognize my internal hard drive. The ‘Install location’ was blank like there was no hard drive. I switched from the 10.5 installer to the Disk Utility on the install DVD and tried to reformat the drive, but Disk Utility was unable to format the drive, giving a ‘Resource Busy’ error.
I finally booted the laptop into Target Disk Mode and connected it an old iMac G4 and was able to format the hard drive that way. Afterwards the 10.5 Leopard intall ran without error.
