Topic: bandwidth and use traffic monitoring

[SR]

Ntop is a fantastic GNU (free) Linux program that is brainless to setup and use, and it provides everything in a nice easy HTML web front end.

Has anyone tried it on an e-smith server?  I will try it tommorow if I have time.

Heres some screen shots

What does it provide...

graph of bandwidth throughput (use) for every few minutes, hour and day.
Each IP address using the internet, the amount of their use and where they have visited.
Colorfull charts and graphs of your network traffic and its breakdown (ftp, http etc.)

I think this should be a part of e-smith because it needs no setup or maint, just install it and let it run.  It auto discovers your network setup and starts collecting stats.  Put a link to stats on the e-smith management page maybe.

It can be a memory hog on a low end machine, but memory is cheap considering the information this will provide, maybe have it off by default and add an on/off (start monitoring/stop monitoring) button.

Opps, sorry for the tripple post... my dial-up went flakey at the wrong time.

Works well. I just run it on another console as required.

How would you run this with e-smith (Newbi to Linux), it looks a good addition.

[SR]

once you have it installed (you may need some help) simply run it from a command line on the e-smith server.  To get to a command line press alt-f2 and enter the login root name and password.  Ntop needs libcap installed and ntop compiled, its easier than it sounds... just download, unzip (tar -xvf filename or gunzip).  Change to the directory created and look at the readme file, the basic is type make clean, make depend, make, make install for each program (libcap and ntop).  Then your ready to go.

heres the command to run   ./ntop -d

If they could add it to e-smith as a standard package it could be installed already and a button could be added to the web interface to run it and then show the monitoring stats.  Would be nice, but it does give detail that may be overwhelming to some.

FYI I seem to found a bug in ntop v1.3.1, when IE5 is used as the browser it crashes the ntop program on the server.  I think it is related to http v1.1.  Netscape works fine.

Thanks for the info, I will work through it and see how it goes.

Just to say what i was looking for was a status screen that showed dialup connect speed and users connected.

Thanks again it will take time to get into this excelent package as a windoze user its a completely diferent ballgame. At this point I feel completely confused.

again thanks for all Help.

There is also an RPM available on ftp.redhat.com, but I did'nt get it running. This RPM is for RedHat 6.2 and e-smith-server 4.0b7 based on 6.1, mybe there is the problem.

Hello

When I'm installing ntop-1.1-5.i386.rpm, available on ftp.redhat.com for RedHat Version 6.2 I get the installation error:

ntop                    ##################################
service ntop does not support chkconfig
execution of script failed

Then I can start ntop but did not see any reported data, despite /var/log/message shows, that the network adapter eth0 is switched into promiscuous mode.
Before that I installed the needed libary "libpcap". Maybe annybody with more linux knowledge than me can give me a little hint what I'm doing wrong.
