Xara Xtreme for Linux, a powerful graphics program |
|
Wednesday, 12 September 2007 |
|
Xara Xtreme for Linux is a powerful, general purpose graphics program for Unix platforms including Linux, FreeBSD and (in development) OS-X. Xara Xtreme is based on Xara Xtreme for Windows . The source code was made available open-source in early 2006, and is being ported to Linux. The downloadable version of Xara Xtreme for Linux is working straight away on most Linux machines, but the development is continuing daily. At the moment two versions are available for download. The first is the recommended download because it will normally be the most stable. The second is the very latest, but untested version, built and published automatically. Warning: It may be unstable. Linux-Tip was using the latest stable version provided as an “Autopackage Archive” on a Open Suse 10.2 Desktop. We recommend connecting your system to the Internet. In this case the script can easily download and install the necessary packages automatically.

This tutorial will show how to configure the network manager to use Cacti and how to set up snmp on the managed host. In this how-to, we are going to run the SNMP server and cacti on the
same host and bind the service to localhost. This way, SNMP service
won't be accessible from the outside. This is a good configuration when
all you want to do is monitoring your home network router for instance.
