This means, if I want to see what web pages were opened by one specific
user(local IP), I need to enable "sticky hosts" or I need to increase
purge hosts to 12 hours, right?
I'll try with sticky hosts. That seems to be the closest to what I need.

You may be speaking of two different issues:
1.) How nTop determines which hosts are local and which are remote
2.) Idle host purge timers
First, please make sure you specify "-m all your local network ranges" on the
command line. Or add via the GUI. This is the only way ntop knows local from remote.
Anything not defined as local is considered remote.
Next, the default idle host purge is 5 minutes. You have two options that I
know of:
1.) Enable "sticky hosts" - which as implies hosts will never go away
until you restart nTop. Only recommended in unique environments.
2.) Change the idle purge time in "globals-defines.h" and recompile
nTop.
Not sure which settings over ride which. If you make a change to the startup
options, you must restart ntop and most/all recorded traffic will be lost. If
done by the GUI, some settings are dynamic, I can't say for sure which ones. I
think the GUI settings are saved in the prefsCache.db file.

Subject: Re: [Ntop] how to monitor http and https only
Even if I choose All protocols --> Traffic . I choose Hosts: All , I
can't see all the remote hosts. But for a while I could see some remote
hosts which than disappeared. What is the effective time range for All
protocols --> Traffic ?
Where are the parameters saved if I use the web interface for changing
the configuration(Admin-->Configure-->Startup options)?
I noticed that if I modify /etc/ntop.conf it overrides the web config
settings. Is that right?
If I modify the /etc/ntop.conf, how can I make the settings effective
without losing the recorded traffic?

There's a startup arg to specify which network ranges are local, it might be
-b? Check the man and make sure you have this configured correctly for your
environment.

Ok, I got confused. Ntop is set on my Centos router. All the internet
traffic goes through it.
I go on the web interface All protocols --> Traffic . I choose Hosts:
Remote only and I see only some of the remote hosts. I don't understand.
Where can I see all the remote hosts which were accessed today?

You can't disable "everything", but with packet and protocol filters, and by
viewing specific reports - you can get pretty close to what you need.

Subject: Re: [Ntop] how to monitor http and https only
Thanks for the hints. But there is still too much information.
All I want is:
- 192.168.0.xxx, between 08:00-14:00, accessed the following sites: ...
- www.facebook.com, between 08:00-14:00, was accessed by the following
local IP-s: ...
I don't need the:
- Host Traffic Stats
- Packet Statistics
- Protocol Distribution
- TCP/UDP Recently Used Ports
- IP Service Stats: Client Role
- TCP/UDP - Traffic on Other Ports
How can I do all these?

Good call. One can also restrict the displayed protocols with -p, all remaining traffic
will be displayed as "other"

Have you taken a look at the manpages for ntop? On a unix system, the "-B"
switch followed by a pcap expression will give you want you want.
e.g
ntop -d -w 8080 -B "port 80 or 443"

Subject: [Ntop] how to monitor http and https only
Hello,
I just installed ntop and it gives me much more information I need. I
would like to see only the traffic on ports 80 and 443.
How can I do that?
