DNSBL feed failed: Domainname length overflow

  • I finally figured out how to use the feeds in the DNSBL and I obtained a number of the usual Easylists that many adblockers subcribe to. However, some of the entries in the list seem to exceed some sort of domain name length. I have included one of the log entries below for reference, but this is happening for multiple lists.

    The reason I'm getting the lists in this manner is due to the included easylist not working (as I would expect them to). I opened the included reference link on the DNSBL page in pfSense to the easylist they use and it's surprisingly short. I suspect this is why it blocks practically no ads. So, I obtained the actual lists and most are working fine and ads are being blocked successfully. However, some of the lists fail with the below error. Is this a known error with a workaround/config change, or am I stuck?

    Easylist location (make sure you get the raw URL for each or it won't work at all):

    Scroll to the end of the string for error code

    You can only use the EasyList Feeds that are hardcoded in the EasyList tab. These ADBlock EasyLists are formatted to remove elements from a webpage while using a browser. DNSBL can only use the lines that are blocking the specific ADVert domains. DNSBL is a DNS filter utilizing the Unbound Resolver.

    You can add other DNSBL feeds:

    Also ensure that you have configured the settings properly for DNSBL to work:

  • It's definitely configured properly as it's working quite well. Also, custom feeds, other than the hard-coded ones, seem to be working just fine. According to the logs, they are being updated, parsed, and added successfully (see example below). Without the custom feeds, barely any ads are blocked. It just seems that pfblockerng complains if one of the lines in the list is over a certain length.

    PS: if you open the default list and one of the lists I provided, you can see they use the same syntax.

    As I stated in my reply above, you cannot use these EasyList feeds by adding them to the DNSBL Feeds tab. They will not parse properly.

    The only EasyList feeds that are usable in DNSBL are hardcoded in the EasyList tab. Only certain portions of the EasyList/EasyPrivacy are useable in a DNSBL filter. See the categories in the EasyList tab to see which categories are usable.

    The next version of pfBlockerNG will have all of the EasyList Language Feeds included.
