Unbound ipv6 problems anyone?



  • Yesterday, I noticed issues with ipv6 dns using dig and nslookup (windows 10). The problem went away but seems to be back. I updated to the latest snapshot, but it made no difference. I also tried adding an ACL, but that also made no difference. I've never added an ACL before.

    I posted about it in the dns section: https://forum.pfsense.org/index.php?topic=132067.0

    Is anyone experiencing this?



  • Current snapshot here - no issues.



  • I reinstalled pfsense 2.4 beta from scratch using the latest snapshot. Still having problems.



  • After flushing dns on the windows and linux clients, dig -6 doesn't return any results.

    I have not changed any unbound settings, other than to register leases and static entries. I tried clearing them but it made no difference, even after restarting unbound.

    How many threads you going to start on this issue?

    See the other thread where looks like -6 is a windows issue with dig.

    I started one thread in DHCP and DNS and since the problem is only on my 2.4 beta system, I started another in here, in case anyone else using 2.4 beta has noticed it.

    It is not an issue with 2.4 or unbound or pfsense at all.. I put in a bug report for the dig -6  this is the response I got

    –--
    We need to update the windows code that retrieves the list of name
    server addresses from the system from GetNetworkParams to
    GetAdaptersAddresses based on a little Googling.

    • GetNetworkParams only returns the IPv4 addresses.
    • GetAdaptersAddresses returns both IPv4 and IPv6 addresses
        depending upon the calling arguments.

    Populating resolv.conf with the nameserver address rather that
    reading them from the system with GetNetworkParams/GetAdaptersAddresses
    will let 'dig -6' work.  This does have the obvious limitation that
    the contents are likely to get out of date as the OS will not be
    updating it.

    'dig -6 @<servername>' works regardless of the method used to
    populate the default server list.

    e.g.
            dig -6 @f.root-servers.net soa .
    ----</servername>

    Thanks for the reply. I didn't have an opportunity to respond further to the other post today, but will try later.

    I asked them for a timeline of a fix, got back


    I don't know at this stage.  Basically when time becomes available to rewrite that section of code.

    heheh ;)

    Damn useful that…. not.

    exactly ;)

    But it doesn't seem to be a big bug - and its only windows related.  Works fine on freebsd and linux.. And you can just use @ipv6ip to make query via ipv6.

    their -6@ipv6fqdn works fine if you direct it towards a root server.  But doesn't seem to work if using record that responds via AAAA.  But works with roots.

    Surely you're not saying that Redmond have broken something? That's so unlike them.  8)



  • I was away for a week and during that time, the systems were idle. When I returned on Monday evening, I updated pfsense and after that, I noticed the problem was gone. (I did not check for it before I updated.) It stayed that way (i.e., nslookup was working) until the most recent update I applied earlier this evening, when the problem returned. I have not made any configuration changes with pfsense or the clients during this time.

    C:\Users\User>nslookup google.com
    Server:  pfSense.localdomain
    Address:  2001:x:y:z:215:5dff:fe5c:e205
    
    Non-authoritative answer:
    Name:    google.com
    Addresses:  2607:f8b0:400a:807::200e
              216.58.216.174
    
    C:\Users\User>nslookup google.com
    Server:  UnKnown
    Address:  2001:x:y:z:215:5dff:fe5c:e205
    
    *** UnKnown can't find google.com: Query refused
    

    The first query from before the update shows nslookup working. The second query from after the update shows nslookup not working.

    Here is output from dig:

    I tried this on two different windows 10 clients. They both behave exactly the same. When they are connected to my pfsense 2.3.4 system, nslookup works. When they are connected to my pfsense 2.4 beta system, nslookup does not work.

    It's possible to ping 4/6 the the clients from pfsense and from other clients. It's possible to ping 4/6 pfsense from both clients. It's possible to ping 4/6 and traceroute 4/6 google.com from the clients. I tried flushing the dns on the clients. dns lookup google.com from pfsense works. The only apparent issue is nslookup.

    All unbound settings are defaults. Previously, I tried enabling an ACL, but that made no difference. DNS servers are not being overridden by dhcp or dhcpv6 or in general settings. Allow DNS server override is unchecked.

    I made zero changes to pfsense other than updating. Is it possible that this problem is related to the unbound changes?

    If anyone has any suggestions to determine what's causing the problem, let me know.



  • I've noticed through the last couple of snapshot updates that after the reboot, it's not working (nslookup and dig @ipv6). If I restart unbound, it works afterwards. I looked in the log and there aren't any messages that indicate any problems.

    The lower three messages are from the reboot after the update. The upper three messages are from restarting unbound.

    And what snap are you on exactly?  What was the last snap that worked?  Just did some basic ipv6 dns testing with

    Current snap..
    2.4.0-BETA (amd64)
    built on Mon Jul 10 04:15:22 CDT 2017
    FreeBSD 11.0-RELEASE-p10

    Going to need some actual info to work with.  What log level do you have set in unbound?  If that is all your seeing my guess would be 0, change it to 1 or 2 are you seeing errors now?  Up it so can see some more info.  Check to see that your listening on ipv6..  See attached.

    Do you have your unbound set to listen on all interfaces or did you select specific ones?  Looks like having an issue binding to my lan link-local address

    But still able to query it via its actual global IPv6 address..  With the info you have provided there is zero chance of anyone helping you..






  • The snapshot is Sun Jul 09 02:22:35 CDT 2017. At the moment, it's still working properly. nslookup returns a result and dig will return the a and aaaa records using either ipv4 or ipv6. My linux box is also working properly. All unbound settings are default. The log level is 1 so apparently, that's the default. I bumped it up to 2. It generates a lot more messages. Nothing that appears to be erroneous.



  • I updated to the latest snapshot and found that the problem returned after the reboot. With unbound logging at 2, there are a lot of messages including some errors (error sending query to auth server <ipv6 address="">port 53).

    Here are the contents of the log in reverse chronological order (newest first). If you scroll down to the bottom, you will see the errors.

  • Another test. I rebooted, found nslookup not working, restarted unbound and nslookup was working. So it seems to be related to rebooting, not necessarily the snapshot.


  • Rebel Alliance Global Moderator

    Its possible your ipv6 is not coming up as fast as your ipv4?  Your dhcp with tracking on your interfaces?  Or maybe your ipv6 is changing on reboot?

    I looked into my error - doh!  Not my lan interface, my wan.. Which has no ipv6 on it so yeah makes sense why the error.  Changed it to no bind to link-local on wan and no more log spam ;)

    It's definitely repeatable that the problem occurs after reboot and persists until unbound is restarted.

    I cleared the logs and rebooted. unbound and dhcp6c appear to be starting up concurrently. Maybe this is the problem.

    Here are log messages from unbound from after reboot to the first error:

  • I should have added that my isp requires dhcpv6 solicit before RA.



  • I updated to the latest snapshot from today and after the reboot, the nslookup / dig problem was back. After restarting unbound, nslookup and dig worked properly. It seems to be a solid problem that restarting unbound is required after a reboot. This time, there were no errors in the log. Since most users do not require the do not wait for RA flag, possibly that's why this is occurring on my system. Are there any tests I should do or log info that I should post? Is this a bug?



  • I think it can be related to https://forum.pfsense.org/index.php?topic=133129.0 not directly but somehow…
    I don't see any other changes regarding unbound last days.



  • @w0w:

    I think it can be related to https://forum.pfsense.org/index.php?topic=133129.0 not directly but somehow…
    I don't see any other changes regarding unbound last days.

    This has been going on for more than a month, so it's not just from the past few days.



  • not on latest snapshot but am using 2.4, no issues with ipv6 lookups using unbound resolver.



  • I just updated and for the first time in a long time, nslookup and dig both worked without restarting unbound. However, I rebooted again to see if it would stick and unfortunately, both were broken again until after I restarted unbound.



  • I suggest you examine your logs to look for indicators of whats going on.

    In unbound settings, disable options to bind to specific interfaces (so it binds to everything) as that can cause the problem you are reporting, basically it starts before ipv6 is up so doesnt bind to it.



  • I noticed watching the console while the system was rebooting that unbound starts well before dhcpv6. I am using the do not wait for RA setting, so PD does not happen until dhcp6c starts. That may be a problem, because dhcp6c and unbound are starting almost concurrently, as you can see from the log messages (in reverse chronological order).

    All of the unbound settings are default. I have not enabled any options to bind to specific interfaces.

    Here are the first few log messages from unbound after booting (note error messages):

  • It would not be difficult to force Unbound to restart on a valid update from dhcp6c, the changes implemented a while back means that it's now possible to differentiate between an a refresh or new lease. However, Chris was having a lot of issues with unbound that I think are now fine and I am not sure if an Unbound restart on a new lease might bring his problems back.

    If you like, I can have a look and send out a patch to you and Chris to see if it works for both of you.

    The other option is a flag to enable or disable an unbound restart on a new ipv6 lease.

    Thoughts.



  • please no :)

    unbound restarting on every dhcp6 renew is crazy.

    As long as the renew keeps the same prefix/ip I dont see why unbound would have a problem.

    Martin I will test the patch tho.  As I expect a new lease wont be triggered on a renew, as long as you also exclude a rebind.



  • :) I did not intend to restart it on a renew or rebind, that would be silly.



  • yeah I know you will find a solution that works for everyone, email me when ready with the patch I will test no problem. :)

    Your optional flag seems a good idea.



  • I'll try and find time tomorrow… if I can stop playing Elite Dangerous :o



  • Something else is afoot here. I have rebooted multiple times, using dhcp6 before RA, and I cannot make it fall over.

    Bimmer, is it possible that sometimes there is a slow response from your ISP for the v6 lease, hence the 'sometimes' its OK?

    It maybe that if that is the case that there is a bit of a catch 22 going on, in that rc.newwanipv6 cannot restart unbound as it's still in the booting up process. Also, and I've not delved into that bit of the code before, unbound is being killed and restarted, if already running, rather than a SIGHUP; I need to study that a bit more to see if there is a reason for that.

    • note *

    Having studied and read Jimp's note that unbound should be killed then that answers that question. Whilst there is already work going on in this area I will not mess with it, too many cooks….



  • Sorry for the slow response. I've been away all week… I'll try running wireshark to see what's happening. I suspect it will the same as it always was. I have a suspicion this problem has been present all along, but I haven't noticed it because unbound was getting restarted so often. Possibly now that it's not getting restarted, the problem is visible. That would explain why I didn't notice it before recently, along with the other changes.



  • I captured icmpv6 and dhcpv6 packets with wireshark during a reboot. Everything appears the way it always has. There are no significant delays in any of the replies.




  • I created bug #7750 "unbound refuses ipv6 queries after reboot" for this issue.



  • I just did another reboot to capture log info. It's consistent that unbound starts before the PD process has completed.

  • I've been trying to recreate this, as I'm also on Telus using dhcp6c before RA, but so far no luck, if I reboot from an upgrade or otherwise, everything still works fine. For curiosity sake, I even looked to see when my unbound is starting and it happens after I get my prefix. I'm running on the latest 2.4 snapshot. I'm in AB on FTTH with the T3200M bridged to port1 with a bare metal install on an SG-2440.

  • That's really strange. Your dhcp6c is running well ahead of mine, relative to unbound.

    I was on a T2200H but just switched to a T3200M. I didn't expect it would make any difference and it didn't.

    All unbound settings are default.

    I've tried a clean install in a fresh VM (running on hyper-v), but that didn't make any difference either.
