[雪峰磁针石博客]python工具库介绍-dubbo：通过telnet接口访问dubbo服务
## 简介 dubbo服务发布之后，我们可以利用telnet命令进行调试、管理。更多资料参见 [Telnet命令参考手册](http://alibaba.github.io/dubbo-doc-static/Telnet+Command+Reference-zh-showComments=true&showCommentArea=true.htm) telnet 调用示例： ```python $ telnet 172.17.103.110 9097 Trying 172.17.103.110... Connected to 172.17.103.110.
