To find elusive reasons why video may not come up, the following two commands should show you why.

tail -f /var/log/dansguardian-av/access.log
tail -f /var/log/squid/access.log

(use ctrl+c to stop the tail)

You may get blocked by the content filter while attempting to view some video. One common provider can cause this. For example, if you use Netflix you may get an error and need to bypass the whole domain for something like the video server for your account (netflix143.as.pop3.nflximg.com.edgesuite.net) in the web proxy.

Some sites will use a 3rd party provider called Brightcove. By exempting Brightcove.com in the ClearOS content filter you will be able to get to some of these sites.

For example, some of the following sites use Brightcove:

To make it a bit easier to digest (as the logs grow pretty quickly!) I also show only entries which have been denied

How would one modify ClearOS settings to access site using www.brightcove.com type video hosting? Gateway > Content Filter > Site List > then add brightcove.com to the Exception Site List (white list)?

As I did this and still found it not working unless the Content Filter was turned off. Humm.

Thank you in advance for your reply!

Hi Michael!


You can try one of the following to find out which site is being blocked.

1. Using the command line:

grep <your ip address here> /var/log/dansguardian-av/access.log | grep DENIED

That will print all of the lines in the content filter's log where your IP address has been denied access to a site.

2. Using the ClearOS Webconfig:

Go to Reports > System > Logs
Choose the dansguardian-av/access.log.
Type "DENIED" in all caps in the Filter field (without the quotation marks).
Check the box to "Show Full Line" display.
Click the Display button.

That will only show you all of the sites that have been denied by the content filter so you'll have to search on the page for your IP address. Looking for a match in the timestamps makes the search quicker as well.

Also, be sure to enter the domain name only and not the entire site name in the Exception Site List.

I hope that helps.
