How to capture and submit a sample of your
logging stream for a possible new version of Link Logger to support
1. Download the Logging Sniffer from
2. Configure your router/firewall to send its logs to the system
running the Logging Sniffer. In this example we are using a
Linksys WRV200 and the system running the Logging Sniffer has an IP
Address of 192.168.1.130
enabled all logging options and remember to save the settings.
3. Run the Logging Sniffer. Note you don't have to install it
or anything, just run it as it is totally self contained and can run
straight from the zip file.
routers/firewalls use Syslog (port 514) to send out their logging
4. Press the
'Start' button to start capturing the logging sample. Your
firewall might ask if its OK for the Logger Sniffer to run, press
5. Generate some network traffic, surf to different sites, get your
email, ping some IP Addresses and visit somewhere like
www.grc.com and run ShieldsUp to
generate some inbound traffic, in short try to generate different
types of network traffic.
NOTE unfortunately not all routers/firewalls log
all traffic. As you can see in this example the Linksys WRV200
only logs outbound traffic and not inbound traffic (attacks for
example). This is why we need sample captures so we can see
what logging functionality a router/firewall has and with what data
format. Since the WRV200 has such limited logging
functionality we will not build a version of Link Logger to support.
Of course this could change if Linksys or some third party developer
releases a firmware version which corrects this logging shortcoming.
6. Once you have collect a sample of different traffic and such then
you can click on the stop button and under the Edit menu select
'Send via Email'
7. Which will create an email with an attached text file containing
your log sample (if you double click on the attachment you can see
the contents of the text file if you wish). Please enter the
Router/Firewall model name and Firmware version as that is a huge
help to us when comparing different router/firewalls and their
Send and thanks for the logging sample. We will evaluate if we
can build a version of Link Logger to support your router/firewall.
Thanks for the sample. We will evaluate its potential for a
new version of Link Logger or if it would use an already existing
version of Link Logger and let you know.
