Looking for good internet monitoring app. for router

[Floog]

I recently put together a routerbox using an old Pentium 166 Mhz with 64 megs RAM, and two NICS--- eth0 goes to the dsl router and out to the internet, and eth1 goes to the internal LAN

It's running Slack 8.0, kernel 2.4.18, and iptables 1.2.6a.

I'm still learning the finer points of nat, masquerading, and appending new firewall rules, but now I need to find a good app. that will monitor and create logs of all internet usage from each workstation behind the routerbox. I want to see:

the internal LAN IP address of the workstation used to browse the net;

what internet sites are being visited--- (displaying the internet sites by name and IP address);

the date and time of all activity;

tracking any downloading/uploading of files; and,

(if possible) tracking of email traffic, both, sent-to and received-from.

I'm getting a little confused by all the different tools out there and was hoping someone could provide a point in the right direction.

Thanks for your time and help.

Thanks for your reply, Mr. Blaze.
I d/l'ed and installed ver 4.2.5 last night from linuxpackages.net. Looks like I can get started with this app.; it's got quite a few configuration options.

Best regards,

Your Welcome , Mr. Floog :D

Yeah snmpd has quite extensive array of monitoring options...i've used it to monitor my squid cache,mail server and router traffic.

If you want to output the monitor to a web interface then look into MRTG for graphs.
