The lab held is in EB2-2027 (access is granted via an RFID-enabled key fob)
- If you do already have an RFID-enabled student ID or key
fob, Marhn Fullmer (our lab manager) or Dan Green (our
system admin) should have already given you access to the
If you don't already have an RFID-enabled student ID or
key fob let the instructor know - we'll fix it.
Check that your access is granted using your RFID-enabled
student ID or key fob on the key reader at the door.
If it doesn't work, contact Marhn Fullmer or Dan Green
(copy me) and tell him you're in ECE470 -- he knows that
you need access to EB2-2027.
- The root password on all ECE470 lab PCs
- If the PC does not start in graphic mode, after login in,
type startx to launch the X Window Manager
On reboot, Linux has its own opinion on which of the two
Ethernet interfaces should be called eth0 and which
one should be eth1. To identify them, you must map
them to physical devices using the command ifconfig
- The interface details for all connections will be shown;
the two wired Ethernet connections are called eth0
- The interface with the MAC address starting
with 00:0E:0C is the Ethernet port on the Intel
Pro card (installed in a PCI slot, card says "Intel Pro"
- The other interface (usually starting
with 00:13:72 on the Dell Precision 380
workstations) is the built-in Ethernet port for the lab
To use a USB memory stick, plug it into one of the USB slots
on a lab PC. The lab PC should auto-mount it
on /media/<drive_name>. Check that it did so
by typing mount.
If you get a line saying /dev/sdb1 at /media/drive (or /media/disk or /media/USB20FSD), the USB is mounted at the directory /media/drive(...).
Accessing this directory will access the USB stick.
If it does not, check if there is a directory in the media directory (i.e. drive or disk).
If not create one.
To mount the USB stick at the directory /media/drive, execute the command mount /dev/sdb1 /media/drive
After the USB stick is mounted, you can access it from this directory.
- You can copy files to and from a mounted USB stick at will.
When you're done working with the USB stick, type umount /media/USB20FD to unmount it before removing it (not doing so may result in file corruption).
Alternatively, if you like to use the mouse, go to Places > Computer, right-click on the USB stick icon, and select "Unmount" before physically removing the stick.
If you can ping from one computer to another but you can't telnet (or ftp), it's most likely that at least one of the two computers (most likely the server) still has its firewall enabled.
iptables -F to disable the firewall, or go to System > Administration > Firewall and click the Disable button.
For the lab report is enough if only one member of the team submits it via Wolfware submit.
Please use plain ASCII text format for submission (not Word, pdf or anything else).
- By default Linux disables broadcast pings -- to enable broadcast pings, use the command echo "0" > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
