About Linux Organization in the Labs

About Linux Accounts

• Following units need Linux accounts:
  • Internet Architecture: (sem 1) ECE4044
  • Wireless Communicatons: (sem 2) ECE4024
  • Performance of Telecommunication Networks: (sem 2) ECE4045
• Home directories:
  • Share the home directories with ra-clay1 and ra-clay2

Linux System: Needed for All Units

• IPv6 enabled
• /dev/ttyS* should be readable and writable by students (check that echo "abc" > /dev/ttyS0 works in an ordinary student account)
• Packet radio modules are used in various 4th year and masters level projects. These udev rules files
  • 99-monash-packet-radio.OLDUDEV.rules (for old kernels), and
  • 99-monash-packet-radio.NEWUDEV.rules (for modern kernels) need to be placed in the /etc/udev/rules.d/ directory.
    If you want to see what's going on with these files, turn logging on in /etc/udev/udev.conf, then /var/log/messages will record the activity.
• Following system services on linux PCs should be active
  1. chargen
  2. chargen-udp
  3. daytime
  4. daytime-udp
  5. echo
  6. echo-udp
  7. finger
  8. time
  9. time-udp
  10. snmpd
  11. sshd
  12. telnetd
• Software development environment
  1. gcc, make etc.
  2. emacs editor
  3. octave (freely available matlab clone)
  4. gnuplot
  5. gifsicle
  6. ppmtogif
  7. xv
  8. xanim
  9. wireshark (was ethereal)
  10. ddd
  11. ImageMagick
  12. sox

ECE4024 Wireless Communications (sem 2)

• We use USB based packet radio modules in the first half of the semester. The udev rules file (see above) should be added to the Linux configuration.

ECE4044 Internet Architecture (sem 1)

• See above -- "needed for all units"
• basilisk.ctie.monash.edu.au is used as the relay computer for the Assignment II.
• Enable IPv6 on basilisk.ctie.monash.edu.au
• basilisk.ctie.monash.edu.au is used for some labs as well. Following services should be running on basilisk:
  1. chargen
  2. chargen-udp
  3. daytime
  4. daytime-udp
  5. echo
  6. echo-udp
  7. finger
  8. time
  9. time-udp
  10. snmpd
  11. sshd

ECE4045/5045 (sem 2)

• See above -- "needed for all units"
• Install OMNeT++
  • Install this version: omnetpp-3.4b2.tar.gz
  • Installation instructions:
    • Open the tar file under /usr/local. It should create a directory called omnetpp3.4b2
    • Create the symbolic link in the directory /usr/local with this command: ln -s /usr/local/omnetpp3.4b2 omnetpp
    • cd /usr/local/omnetpp
    • ./configure (check Installation help for problems and solutions)
    • ./make
  • Make sure that the directories (755) and files (644) are readable by ordinary users.
  • Ordinary users should have

                     export PATH=$PATH:/usr/local/omnetpp/bin
                     export TCL_LIBRARY=/usr/share/tcl8.4
                     export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/omnetpp/lib

• Test the OMNeT++ installation through simulating the hypercube model (login as an ordinary user first)

                     cd ~
                     cp -a /usr/local/samples/hcube .
                     cd hcube
                     opp-makemake
                     make
                     ./hcube
