To test all the ntopng pages and check for crashes it is possible to recursively visit all pages automatically ntopng can be started as follows - ntopng -i ethX -l 0 This disables login check (-l 0) for automatic testing. After start, you can programmatically visit all pages as follows: - wget --recursive --no-parent http://localhost:3000 that in essence will navigate all the pages and save them to disk.
