AIX iptrace Recipe

  1. Review the security and performance implications of network trace.
  2. As root, start the capture:
    startsrc -s iptrace "-a -b -B -L 2147483648 -S 80 aixiptrace.bin"
    1. This captures up to 2 files of 2GB each of up to 80 bytes per packet. Set -S 1500 if you want to capture full packets although this has a higher overhead.
  3. Check for any errors running the above commands in your terminal.
  4. Reproduce the problem.
  5. Stop the capture:
    stopsrc -s iptrace
  6. Upload aixiptrace*.bin*
