AllJoyn -如何让bbclient ping bbservice，当它们运行在通过以太网电缆连接的不同Linux设备上。

Question

AllJoyn框架版本15.09.00a用于在Linux平台上构建bbservice和bbclient应用程序，用于执行以下测试。

如果使用以下命令在同一个Linux设备上运行bbservice和bbclient

bbservice -n com.test &
bbclient -n com.test -d -c 5 &

则bbclient可以成功ping通bbservice 5次。

下面是此测试的输出。

bbservice -n com.test &

如果bbservice运行在IP地址为192.168.1.1 Linux设备上，而bbclient运行在另一台IP地址为192.168.1.2的Linux设备上，则bbclient无法找到并ping通bbservice。这两台Linux设备通过以太网线相连，可以通过Linux ping命令相互ping通。

下面是此测试的输出。

(在192.168.1.1 Linux设备上)

bbservice -n com.test &

AllJoyn Library version: v15.09.00
AllJoyn Library build info: AllJoyn Library v15.09.00 (Built Mon Feb 29 22:13:06 UTC 2016)

(在192.168.1.2 Linux设备上)

bbclient -n com.test -d -c 5 &

AllJoyn Library version: v15.09.00

因此，当bbclient在不同Linux设备上运行时，需要做些什么才能使bbclient能够ping通bbservice。

Answer 1

Linux设备上存在网络问题，导致bbclient在这些Linux设备上运行时无法ping通bbservice。

修复网络问题后，bbclient可以成功ping通bbservice。
