Hi,
I was able to reproduce the behavior you describe. However, it seems to
me that this is "by design", and that out of the box ntop is configured
to show only the protocols listed in /etc/ntop/protocols.list. It's not
meant to be an exhaustive list of protocols but rather, a "filter" to
show only those specified there.
Documentation for the -p option says:
This parameter is used to specify the TCP/UDP protocols that ntop will
monitor. The format is <label>=<protocol list> [, <label>=<protocol
list>], where label is used to symbolically identify the <protocol
list>. The format of <protocol list> is <protocol>[|<protocol>], where
<protocol> is either a valid protocol specified inside the /etc/ser‐
vices file or a numeric port range (e.g. 80, or 6000-6500).
A simple example is --protocols="HTTP=http|www|https|3128,FTP=ftp|ftp-
data", which reduces the protocols displayed on the "IP" pages to
three.
If you need ntop to monitor *all* protocols, you need to do so
explicitly by removing the -p parameter from the startup file, as you
have described. However the packager may have considered that this was
too much for most people and thus chose to add a limited list of
protocols as a starting point.
Since this seems to be "by design", I'd be inclined to mark this bug as
Invalid. Do let me know if this seems incorrect. I won't touch anything
until I hear your opinion on this matter.
Thanks!
