I have just finished my reading on the sguil user mailing list. One interesting mail caught my eyes of which asking whether can have netdude replacing the ethereal since ethereal is not available in OpenBSD port anymore. So I just tried out to see if it works since I have netdude installed previously, here we have another replacement to ethereal - Netdude :).
If you don't know what is netdude, check out the link below.
Hereby with the screenshot of it, seeing is believing ......
