DSNBL error: connect: Can't assign requested address for 127.0.0.1 port 953



  • I can't get this to work properly as I continue to get this error below. I have look around forum and internet to try a few things but have not found anything that works yet. Newbie to PfblockerNG but would like to get it working if anyone can help.

    Reloading Unbound Resolver..

    [1549436537] unbound-control[77716:0] error: connect: Can't assign requested address for 127.0.0.1 port 953.... Not completed.

    I found this page talking about the same issue but no resolution besides resetting and starting over which I would prefer not to do.

    And did you follow the steps in that thread were they ask you to look what is running on that port.. Lets see your sockstat output

    example here is mine

    [2.4.4-RELEASE][root@sg4860.local.lan]/root: sockstat | grep :953
    unbound  unbound    68997 29 tcp4   127.0.0.1:953         *:*

    sockstat

    It shows this:

    unbound unbound 92099 22 tcp4 127.0.0.1:953 :

    so unbound is already listening, if it doesn't stop when asked, etc. then sure you can have issues if your trying to run another instance for example.

    Lets see your logs, can you stop unbound and restart it from the gui, does it stop and start - can you do it from the cmd line... The info on how to do that is in the thread you linked to.

    Saying there is no solution there is because you have not given the info required to figure out what the problem actually is. Just like the guy in that thread. The person asking all the questions and giving great advice is the writer of pfblocker ;) bcan177 if anyone can help it would be him. But without details nobody can help.



  • Sorry, I am a newbie. Which logs do you want, from PFblockerNG logs or system logs? How do I download system logs?

    I can stop and start it from the GUI. I just stopped it from the GUI and tried force reloading DNSBL update which then started unbound again. Message now is this.

    @snowmanut

    Try to go to pfSense Resolver, Advanced page, and change the Log Level to "2" , then hit save.

    Then review the resolver.log in pfSense system logs to see if you have any other errors? If there are, try to address those first.

    Otherwise, there could be a bit of a race condition with the widget. So first try the above, if that doesn't pan out, goto the pfSense dashboard and click the wrench icon in the pfB widget. Change the Resolver query setting from "5" to "60" seconds. then save. Then run a Force Reload - DNSBL.

    @johnpoz Thanks! Am on holidays but still on duty :)



  • I have a bunch of the same error on the Resolver log. This is just a part of the error but they all say duplicate forward zone. Not sure what that means??

  • Got rid of errors in DNS resolver log by removing all my DNS servers in the general setup page.

    I changed the Resolver query setting from "5" to "60" seconds and did the reload but back to the same error:

  • Maybe you should do a Force Reload All then post your pfblockerng.log to see what happens.



  • 0_1549494634044_pfblockerng.log.txt

    Ok, removed the package completely and reinstalled it just to try. Went through the wizard again and back to the same error.

    pfblockerng.log attached



  • How did you configure DNS Resolver ?
    What pfsense version, platform, pfblockerng version, which package are you using?



  • PFsense version: 2.4.4-RELEASE-p2 (amd64)
    pfBlockerNG-devel net 2.2.5_21
    Platform: HP T620 Plus Thin Client

    DNS Resolver setting:
    -Network Interfaces: all
    -Outgoing Network Interfaces: WAN
    -System Domain Local Zone Type: Transparent
    -DNSSEC Support: Enabled
    -Custom Options: server:include: /var/unbound/pfb_dnsbl.*conf
    -Host override for a duckdns domain I have setup.

  • @snowmanut said in DSNBL error: connect: Can't assign requested address for 127.0.0.1 port 953:

    -Host override for a duckdns domain I have setup.

    And if you remove the host override do you still have the same symptoms?



  • Deleted host override, no change. Same error after force reload.

    Can you try to disable DNSBL, then run a force Update.
    Enable DNSBL then run Force Update.

    If you still have errors, then enable only on DNSBL group with only one URL enabled, run a Force Reload DNSBL and see if it reload unbound.

    @snowmanut said in DSNBL error: connect: Can't assign requested address for 127.0.0.1 port 953:

    by removing all my DNS servers in the general setup page.

    Why would you have DNS servers listed in the general setup page if your using unbound in resolver mode? Having there sure would not cause any errors since they would never be used, unless you told pfsense not to use 127.0.0.1?



  • When I deleted all the DNS servers in there it wouldn't download any packages from the package manager. When I put 1 back the package manager worked again. Others reported similar behavior on other posts.

    I don't think I have told it not to use 127.0.0.1, where would I do that besides the DNS resolver which we already checked?


  • LAYER 8 Global Moderator

    Lets forget pfblocker for a second... Does unbound work when not using pfblocker? Disable pfblocker does your resolver work as it should..

    Its right there in the general setup - where you would of set extra dns
    0_1549507427683_disableloopback.png

    I would also uncheck allowing your ISP to hand you dns via dhcp... That checkbox above the one I point out.

    Pfsense out of the box resolves, and the only thing it should point to for dns is itself
    0_1549507542208_onlythinglisted.png

    If you are having issues with unbound working, I would figure that out before you worry about package like pfblocker



  • None of those were checked on general setup. If I remove all DNS servers from the DNS server list the package manager fails to download anything.

    Package Manager Blank with no DNS Server listed in setup:
    0_1549517573819_Package manager.JPG

    Would having comcast have anything to do with this?



  • Did you try to do nslookup from the pfsense ?


  • LAYER 8 Global Moderator

    Sure your isp could be doing something - but I was on comcast for years and they never dicked with dns that I recall.

    Yes try to look up something else, does google resolve? Go to diag, dns lookup - try some stuff in there does anything work?

    What does your status resolver show you?
    0_1549537902724_resolver.png

    What does the log show is unbound actually starting and listening on 53?

    You have pfblocker disabled right? Lets actually validate the resolver is working how it should before you try and throw pfblocker on top of it. Not able to list packages doesn't bode well for a fully functional resolver.

    You don't have some vpn setup - what other packages are you running? This should be a clean out of the box pfsense setup!

    You don't go throwing extra toys onto something that isn't working in the first place ;) If your ISP is dicking with DNS then you could always use forwarding mode with unbound. But lets actually validate that first, etc.



  • PfblockerNG is off. Ran DNS Lookup and no response on google or pfsense. I can still go to websites when browsing though, weird.

    0_1549553606883_Google-no resolve.JPG

    Status of DNS Resolver is blank too:

    I have OpenVPN setup for access by my phone to my network. I can disable it. Used this video guide to do it on Lawrence Systems / PC Pickup: https://www.youtube.com/watch?v=7rQ-Tgt3L18&t=656s Works fine for when I need access.

  • LAYER 8 Global Moderator

    well from that unbound is not running... So how would your clients resolve anything unless they were suing something else for dns..

    Unbound is not working... Get unbound working before you attempt to get pfblocker working.

    Restart unbound - what does the unbound log say. UP the log level in unbound.



  • Already have log level at 2, do I need to go higher?

    Looks like it is resolving??

    0_1549558669749_Unbound logs.JPG



  • Still trying figure this out. Unbound is stopping and starting all the time per the logs. Still have forwarder off and no DNS servers in general setup. Pfblocker is turned off. DNS resolver status blank and dnslookup doesn't resolve anything? Is my boxed just messed up or is there issue with unbound or how do I fix this?

  • https://forum.netgate.com/topic/104772/unbound-restarting
    https://forum.netgate.com/topic/138449/unbound-restarting-more-frequently

    Also if you use the Service Watchdog package make sure it does not monitor unbound.



  • @BBcan177 fixed my issue which was unrelated to pfblocker. Somehow my Pfsense became corrupted related to the unbound_control.key and unbound_server.pem. He got it to generate new ones that fixed unbound which in turn got Pfblocker working. We are not sure why it happened but he is reporting issues to them. Owe him for sure, great guy.
