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，以便在下面执行这些测试。

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

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

然后bbclient可以成功ping bbservice 5次。

以下是此测试的输出。

bbservice -n com.test &

bbclient exiting with status 0 (ER_OK)

如果bbservice在Linux设备上运行，IP地址为192.168.1.1，而bbclient在另一台IP地址为192.168.1.2的Linux设备上运行，则bbclient无法找到并ping bbservice。这两个Linux设备通过以太网线连接，并且可以通过Linux ping命令相互ping通。

以下是此测试的输出。

（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)
opts.transports = 0x105
bbservice com.test ready to accept connections

（在192.168.1.2 Linux设备上）

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

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

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

修复网络问题后，bbclient可以成功ping bbservice。
