Setting up Syslog
Add the following code for syslog configuration in knoppix.sh.
Note that SSH is on only for this demo.
The use of ipv6 is becauase the virtual machine is networked over ipv6.
Port | Use | Information |
|---|---|---|
8100 | NPAD Control | Does not respond to HTTP |
8200 | NPAD | Traceroutes |
3765 | Reverse (SLAC) Traceroute server | cgi scripts |
3001 | Network Diagnostics Tool | Performance testing port |
7123 | Network Diagnostics Tool | web frontend to java applet for performance tests |
4823 | bwctl | bandwidth measurement |
861 | owamp | One way delay measurements |
On top of this list, iperf instances instantiated through bwctl must also have some ports (tcp) open for tcp tests. The default range is 5001-5100.
Also NPAD requires ports 8002-8020 open.
Setting up Syslog
The syslog daemon starts on default. It can be customised with a copy of the syslog.conf file.
Add the following code for syslog configuration in knoppix.sh.

if [ -f /UNIONFS/media/$MNT/NPTools/syslog.conf ]; then
restore_NPT_file $MNT syslog.conf /etc/
fi

The standard syslog.conf was copied from the slac machinesused from a slac machines (however, as netlog is accessible from anywhere by the slac subnet, this may be somewhat limited).
