Exercise Goals • Get you familiar with the tools we use for configuring, testing and analyzing the MSR • Get you familiar with building and running an MSR MSR Tutorial • Not worry about a lot of MSR internal details Group Exercises Washington Washington fredk@arl.wustl.edu Fred Kuhns - 6/24/2003 2 WASHINGTON UNIVERSITY IN ST LOUIS WASHINGTON UNIVERSITY IN ST LOUIS General Info General Info (continued) • Each group will be using 3 PCs • MSRs are configured with serial cables to SPCs on Ports – Data Source ($DSRC) Linux 4 and 5. See aliases spc4 and spc5 in the readme file and – Monitor Switch Control Processor ($SWCP), NetBSD your login script. – MSR Control Processor ($MSRCP), Linux • We are going to be configuring and testing a router based • All utilities work on both Linux and NetBSD on the WUGS and SPCs from the hardware on up. • You must use NetBSD when building: • There are a LOT of details involved. Your login script – MSR Kernels and Plugins defines macros/variables to simplify the configuration • The exercises will start out by giving you very specific process. In particular the hosts are defined by the directions. variables: • Later exercises leave out some details that you should – MSRCP, SWCP and DSRC be able to fill in from what you learned in earlier exercises.
