Pkviz is a tool for plotting and cycling through and animating a series of network packets captured by tcpdump. What makes it unique is that the packets’ structure is visualized, not any labels and not time itself. Pkviz takes each byte in a packet and plots it out end-to-end, left-to-right, from the first byte to the last. How high the dot gets plotted depends on the value of the byte: bytes with a value of 0 are at the bottom and those which are 255 (0xff) – the maximum value of a byte – get plotted at the top. This might not be interesting for one packet, but that changes when you start looking at thousands of packets. Pkviz can cycle through thousands of packets in the set so you can see what happened on the wire.
Quota Check is a simple application which is designed to run when a user logs into a computer. If they have less than a certain amount of free disk quota, they are told to visit the system administrator and are logged out. When a user tries to log into a network home directory which has a quota enforced, and they don't have enough disk space, they risk corrupting their files. Quota Check makes this situation very clear to users who may be otherwise unaware of the problem.
