Ease of Use:
Pros: Excellent reporting.
Cons: Too many false positives.
| Link Logger is a
program that logs all the events on your Linksys Router.
Simply set your Linksys router to send all logs to the
computer where you're running Link Logger, and you'll have an
instant view of all the traffic that hits your router.
The interface is quite good. It has a Traffic
section, Detail section and History section. All the logged
traffic shows up in the Traffic section. You can apply a
filter remove "normal" traffic so you won't see all
your own web-browsing in the logs. This is the preferred
setting for me, as I get quite a bit of incoming and outgoing
Web-traffic. Double-clicking on an entry in the Traffic
section will copy the information down to the Detail section.
Here, Link Logger will attempt to do a reverse lookup on the
IP addresses, list the Alert info on the port numbers, and
also provide a URL where you can read more about the potential
exploit. Unfortunately, Link Logger gives you too many false
positives, so you might end up having to sort through a fairly
large list of alarms. From the Detail section, you can add the
ports and/or IP address to the Port/IP alarm list, or load the
port/IP history. The later will show you all entries in the
database matching the IP address or port number. Quite handy
when you want to check what someone is trying to do to your
As briefly mentioned earlier, there's an IP and port
alarm list. Here you can define IP addresses and ports that
will generate an alarm. Enter port 80, and you'll get an alarm
every time someone probes your router for Code Red (you'll
turn that off pretty fast!). If you are doing port forwarding,
you can enter that information into Link Logger as well, and
it'll stop alerting on traffic going to your server(s). And,
there's also a trusted IP address list. Addresses listed here
will not generate any alerts.
Link Logger also has a handy Report generator. It
displays different types of information as 3D pie charts so
you can easily spot the most popular activity on your router.
The charts can also be exported as a bitmap or metafile, or
simply copied to the clipboard. Very nice feature.
In short, a good product for logging the activity on
your Linksys router. I hope they'll work on it some more to
reduce the number of false positives.
