To enable debugging and generate the CDT:
  1. Connect to IWSVA via SSH as the "root" user.
  2. Activate the debug mode:
    1. Open the /var/iwss/intscan.ini file using a text editor.
    2. Look for the following entry:
      [http]
      #Switch for debug log
      # 1 -> turn on
      # 0 -> turn off
      verbose=0
    3. Change the verbose line to "1" so that the entry should look like:
      [http]
      #Switch for debug log
      # 1 -> turn on
      # 0 -> turn off
      verbose=1
    Note: If you need to do the same for FTP, look for the same section for this protocol, which starts with [ftp] and provide the same option to turn on verbose mode.
  3. Restart IWSS deamon by using the following commands:
    /var/iwss/S99ISproxy stop
    /var/iwss/S99ISproxy start
    Note: For FTP, replace S99S99ISproxy with S99ISftp in the command above.
  4. From the shell, capture network traffic using the following command where ddmmyy is for the date of the capture.
    # tcpdump -s0 -i eth0 -w /tmp/iwsva_debug_ddmmyy.pcap
  5. Stop capturing the network traffic from the appliance and save the files by pressing CTRL + C. This will save the .pcap file created in point 3 as described above (i.e. /tmp/iwsva_debug_ddmmyy.pcap).
  6. Launch the CDT using by running the following command:
    # su iscan -c "/var/iwss/CDT_IWSS.sh -d /var/iwss/UserDumps
  7. Check the CDT output saved in the folder /var/iwss/UserDumps. The file format will appear as: Info_<date>_<Timestamp>.tar.gz.
    Note: To get the file, connect to IWSVA using WinSCP over SCP protocol. Use the root account.
  8. Revert the change made by disabling the verbose logging level:
    1. Open the /var/iwss/intscan.ini file using a text editor.
    2. Look for the following entry:
      [http]
      #Switch for debug log
      # 1 -> turn on
      # 0 -> turn off
      verbose=1
    3. Change the verbose line to "0" so that the entry should look like:
      [http]
      #Switch for debug log
      # 1 -> turn on
      # 0 -> turn off
      verbose=0
  9. Restart IWSS deamon using the following commands:
    /var/iwss/S99ISproxy stop
    /var/iwss/S99ISproxy start
    Note: For FTP, replace S99S99ISproxy with S99ISftp in the command above.
