本篇文章主要介绍了"\t\trdesktop架构解析(RDP协议分析)",主要涉及到\t\trdesktop架构解析(RDP协议分析)方面的内容,对于\t\trdesktop架构解析(RDP协议分析)感兴趣的同学可以参考一下。

 本文立足于rdesktop的架构层次进行解析,算是抛砖引玉,国内对RDP协议深入解析的资料到本文发布时为空白!调用层次: rdp_--->sec_--->mcs_--->iso_--->tcp_协议包编解码层次: rdp_hdr->sec_hdr->mcs_hdr->iso_hdr->data,所有这些指针组成一个STREAM.view plaincopy to

*sec_hdr; unsigned char *rdp_hdr;} *STREAM; 主过程:1.rdp_connect: 按照调用层次依次调用sec_connect……,然后调用rdp_send_logon_info发送登录请求验证信息.其中rdp_send_logon_info调用sec_init初始化数据包,调用sec_send发送数据包,根据flags(包含加密标识)调用加密处理逻辑.2.然后进入rdp_main_loop循环,调用rdp_recv,根据触发的事件类型做相应处理。3.rdp_disconnect,按照调用层次依次调用sec_disconnect……断开。特殊的,在iso_disconnect中首先调用iso_send_msg(ISO_PDU_DR)发送PDU消息包,然后再调用tcp_disconnect 断开连接。view plaincopy to clipboardprint?01./* ISO PDU codes */  02.enum ISO_PDU_CODE   03.{   04.    ISO_PDU_CR = 0xE0,  /* Connection Request */  05.    ISO_PDU_CC = 0xD0,  /* Connection Confirm */
