Network monitoring

You don't say what sort of monitoring you need, but one possibility might be Ntop from http://www.ntop.org/

monitoring the 3 network card activity and record any hacking activity from outside

That sound more like you are after an Intrusion Detection System (IDS). Probably the best of those is Snort (http://www.snort.org/).

will the snort have the gui interface so i can how the traffic going

Snort doesn't do traffic statistics it is only conerned with detecting intrusions. I don't know of any tools that do both.

so i can "??" how the traffic going??

NTOP will give you a html based front end to view traffic, where it is going, where it came from, packet size, protocol etc - excellent tool
snort, with an additional front end like snortcenter will give you details on packet payload, to/from etc etc
"Snort is a software-based real-time network intrusion detection system that can be used to notify an administrator of a potential intrusion attempt."

A good article on setting up and using snort can be found at

i already download the ntop, the ntop-3.0-0.i386.rpm. I recieve a error:

Packages Not Found

libgd.so.1.8           ('ntop','3.0','0')
libgdome.so.0       ('ntop','3.0','0')

what is this actually?

I don't see an rpm specifically for Fedora. What did you download?

FYI: In the general case unless you can find an rpm built specifically for the Linux distro/version you are running you'll be better served by getting an SRPM or a source kit and building your own copy.

i download it from ntop.org. but i choose the download for redhat version.

so what are the best network monitoring  for fedora cora 1 and running under kde?

fedora core 1 rpm can be found at http://dag.wieers.com/packages/ntop/ntop-2.2-0.rhfc1.dag.i386.rpm

Packages Not Found

libgd.so.1.8           ('ntop','3.0','0')   - this is provided by gd -http://atrpms.net/dist/fc1/gd/
libgdome.so.0       ('ntop','3.0','0')    -  this is provided by gdome - http://download.atrpms.net/production/packages/fedora-1-i386/atrpms/gdome2-0.8.1-3.rhfc1.at.i386.rpm

why when i install the rpm file, there is icon showing for installing at my cursor. but then nothing happen. is it i have to install it manually?

I don't understand what you are saying.

install the rpms' from a command line using rpm -ivh file.rpm
If you have further trouble copy and paste the results from your install attempt into a comment.

If all goes well edit /etc/ntop.conf to your needs and then start ntop with "service ntop start" from command line. Open up a browser and go to http://localhost:3000

ok will try

this the error message:

first i try to install ntop...the error come out...the system want the libgd.so.2..so i install the libgd...then i try installing again the ntop....and below is the error output.

and the i try to install forcely by using this command rpm -ivh --force ntop-3.0_fc-0.i386.rpm

and at Services..i can see the ntop service is check and running but the status are:

ERROR -
        Configuration file /etc/ntop.conf does not exist!

Aborting...

i already install it succesfully...but i see only basic function...i cannot see what are the lan client surfing and what ip is accessing my server...or to spesific server such as who access the ftp server, who access the web server...

any other monitoring better than ntop?
