Question

我在192.168.1.191上设置了Consul Master，在192.168.1.198设置了Agent。

我在Consul Master中尝试使用dig命令，它可以工作：

# dig @192.168.1.191 -p 53 kafka.service.consul. ANY

; <<>> DiG 9.9.5-3ubuntu0.5-Ubuntu <<>> @192.168.1.191 -p 53 kafka.service.consul. ANY
; (1 server found)
;; global options: +cmd
;; Got answer:

为什么呢？似乎Consul不能处理来自其他节点的请求。任何帮助将不胜感激。

但是，当我在Consul Agent中尝试dig命令时，我收到了一条超时消息：

# dig @192.168.1.191 -p 53 kafka.service.consul. ANY

; <<>> DiG 9.9.5-3ubuntu0.5-Ubuntu <<>> @192.168.1.191 -p 53 kafka.service.consul. ANY
; (1 server found)
;; global options: +cmd
;; connection timed out; no servers could be reached

以下是Consul Master上的TCPDump命令的输出：
