接着对使用coTurn搭建的STUN/TURN服务使用turnutils_uclient程序测试其TURN服务是否正常。
直接连接服务测试服务是否正常。为保证测试使用的服务是TURN服务，在TURN服务启动时，关掉STUN服务。
在TURN服务启动时，如果是命令行，加入"--no-stun"配置；如果使用配置文件的话，加入"no-stun"选项。
使用coTurn服务启动TURN服务后，执行以下命令即可：
turnutils_uclient -v -t -T -u test1 -w 1234 61.18.11.123
其中
-v 表示给出详细提示
-t 使用TCP协议（默认使用UDP）
-T TCP协议中继传输（默认是UDP）
-u TURN的用户名
-w TURN服务对应用户的密码
61.18.11.123 TURN服务的IP地址
执行结果如下:
