linux下多人聊天室

客户端

一个在Linux下可以使用的聊天软件,要求至少实现如下功能:
1. 采用Client/Server架构
2. Client A 登陆聊天服务器前,需要注册自己的ID和密码
3. 注册成功后,Client A 就可以通过自己的ID和密码登陆聊天服务器
4. 多个Client X 可以同时登陆聊天服务器之后,与其他用户进行通讯聊天
5. Client A成功登陆后可以查看当前聊天室内其他在线用户Client x
6. Client A可以选择发消息给某个特定的Client X,即”邮件”功能
7. Client A 可以选择发消息全部的在线用户,即”群发消息”功能


可以选择实现的附加功能:
送欢迎你来到咱们的聊天室”
