WRV200 - saving network traffic?

Hello,

I've got Linksys WRV200 and I have a question about LOG option (Administration/Log).

I want to know how does it work?

Does it work like that: When the user abc enters the website facebook.com, I will receive a raport about this act to my mail?

Or that router just saves/logs all Internet traffic?

Thanks for answers!

You can set up logging to see the inbound and outbound traffic, and have it emailed to you,

or you can set up a syslog server to save the logs to a file, then process them later.

tftpd32 is a good small syslog (and dhcp, tftp, etc) tool

kiwi, and solarwinds have demo or free versions of their log tools

I don't think the logs actually show the web site the user is going to.  but some of these tools allow you to resolve IP addresses to the site.

Sawmill is an open source tool to parse the log files, Also, here's a good list of tools.

Thanks for your reply. :)

So as I understood the logs don't save all Internet traffic like:

2012/08/14 12:00 - 192.168.2 - google.com

2012/08/14 12:02 - 192.168.2 - ebay.com ??

So can you show me example of that logs? That logs are only for external Internet attacks or what? I am afraid that I still don't understand it in the proper way.

Thanks for help! :)

The logs generally show connections with the IP address and port number that the clients are going to, or outside connections coming in.  there may be system status, vpn, and other messages included.

I would suggest download one of the syslog tools, and look at the logs on your device to see if they do what you want. if not they may need some post processing (dns name lookup, filtering, alerting etc)

Here's a sample (the x.x.x.x  are real internet addresses).  But the format and features may change depending on the version of firmware on your device, and the capability of the syslog server you are using.
