- Troubleshooting
- My experiment setup failed, what did I do wrong?
- My experiment is set up, but I cannot send packets between some of the nodes. Why?
- I asked for traffic shaping, but everything seems to be going at full LAN speeds
- I set a non-zero packet-loss (or delay) but 'ping' shows no packet-loss (or delay)
- I set a non-zero packet-loss (or delay) but 'ping' shows a different packet-loss (or delay)
- I decreased the bandwidth on a link and now the ping time between the nodes has increased
- I wrote a small TCP application to test the bandwidth of a link/LAN, but I do not observe the bandwidth that I asked for.
- I wrote a small UDP application to test the bandwidth of a link/LAN, but I do not observe the bandwidth that I asked for.
- I am running a routing daemon in my topology but the daemon claims that all my nodes are directly connected!
- My custom Linux kernel won't boot, why?
- Why is the per-packet latency so high (variable) on the pc3000 nodes?
- Why isn't my multicast traffic being correctly shaped?
- Why does my NS file not parse correctly anymore?
- I got an error in my swapin that says 'Temporary Resource Shortage' - what does it mean?
- I am running into errors while working in my home and/or project directory (or subdirectories). What's going on?
