Xepr Under Linux 18 Bruker delivers either SGI O2 or Linux workstations for the user interface of the Elexsys series EPR spectrometers This chapter describes various system administration issues related to the Xepr program for the Linux workstations The names terms or methods described in this chapter may be slightly differ ent for the SGI O2 system but the principles are the same Refer to Chapter 18A and SGI documentations for details if you have an SGI O2 workstation Most of the commands and operations in this chapter require root or super user privileges In addition the commands also require at least some basic knowledge of the UNIX operating system This chapter assumes that you already are familiar with general administration of the Linux operating sys tem There are many web sites and documentation describing Linux adminis tration Be cautious when making changes to the workstation configuration some mistakes can lead to an unusable workstation Consult your local Bruker EPR service representative if you are unsure of the changes you are making General Information 18 1 The Linux workstation comes with two Ethernet cards Most of the GUI Graphical User Interface operations in this chapter are based on GNOME the default desktop manager If you prefer to use other GUIs refer to the cor responding manuals and documentation Much of the configuration is based on Red Hat Linux 7 0 If your workstation is not running under Red
