BIND9 DNS 服务器 - 大量查询失败,并引用 SERVFAIL 和 EDNS

BIND9 DNS 服务器 - 大量查询失败,并引用 SERVFAIL 和 EDNS

我正在运行自己的 BIND9 服务器,该服务器在本地网络中的 Arch Linux 上运行。自从运行该服务器以来,我开始在浏览器中收到各种错误(Android 6 上的 Chrome)。这些错误通常会同时连续出现:

  • DNS 探测错误
  • 错误名称未解决
  • err_timed_out(更新四

只需单击错误消息并尝试重新加载页面,大约 30 秒后问题就会自行解决。我的日志没有显示任何可疑条目(journalctl -r -u named)。我发布了我的 bind9 配置以及下面的相关/正在运行的区域。是否有人可以指出任何明显的问题?我很乐意根据需要生成更多配置/日志文件或运行任何测试。我可能还应该提到我在同一台机器上设置了一个 dhcp 服务器。此外,该框还在带有 qemu 虚拟机管理程序的 kvm 中使用 libvirt 托管 windows server 2016 客户机。我在下面附上了ˋip addr showˋ 的输出。

更新一:再次检查我的 DNS 服务器日志后,发现确实有许多失败的查询。现在正在分析。日志附在最底部。感谢任何指点。谢谢!(我不是系统管理员,也不是软件开发人员,所以这真的不是我的专业领域)

更新二:通过明确设置要监听的地址可能解决了我的问题。在本例中:(listen-on { 192.168.1.35; };/etc/named.conf)。将监控日志并最终在接下来的 24 小时内确认。

更新三:我的 dns 服务器日志中仍然收到servfail错误,但自从明确设置要监听的 ip 地址以来,我还没有收到此设备上的浏览器中的任何错误,而且我也觉得查询性能有所提高。后者当然是非常主观的。错误servfail指向query.c第 8298 行的 C 文件。我还在研究edns-udp-size与我的路由器/互联网调制解调器相关的 bind9 参数。我曾经将 Telekom Speedport W920V 刷入 AVM FritzBox 7570 vDSL,我仍然将其用作我的 vDSL 调制解调器/路由器。仍然非常希望得到一些指点。干杯。

更新四:如上所述添加了额外的浏览器错误。此外,正如 UIII 中提到的,我正在EDNS-UDP-SIZE根据以下日志条目查看该参数:

Feb 07 19:05:01 nas named[10928]: success resolving 'clients4.google.com/A' (in '.'?) after reducing the advertised EDNS UDP packet size to 512 octets
Feb 07 19:04:54 nas named[10928]: client @0x7f7a18204640 192.168.1.31#14927 (clients4.google.com): query: clients4.google.com IN A + (192.168.1.35)

答案1

问题已经得到解决。我创建了一个github 仓库我在其中添加了所有相关的命名配置文件以及日志,以便比较命名服务器的损坏配置版本和正常工作配置版本。最终我无法真正确定问题所在,但可能是我的正向和反向区域配置错误。在我的正向区域中,声明 NS 记录时,我添加了域,如下所示

muncic.local.  NS  IN  nas.muncic.local.

代替

NS  IN  nas.muncic.local.

在我的反向区域中,我发现一条 PTR 记录未使用正确的值

35                     IN   PTR 35.0.1.168.192.muncic.local.

代替

35                     IN   PTR nas

我还对我的 named.conf 绑定进行了各种更改,将其命名为在 192.168.1.33 上运行的第二个有线接口 enp6s0。

这是我在修复前后分别大约 24 小时的 journalctl 输出:

$ journalctl -u named --since="2017-02-12" --until="2017-02-13" | grep  SERVFAIL -c
67
$ journalctl -u named --since="2017-02-14" | grep  SERVFAIL -c
0
