Ciscopackettracer为什么远程主机的连接被拒绝

意思是客户端使用远程连接软件向服务器发起连接请求，但被服务器拒绝。
引起远程连接拒绝服务的原因有两种。第一种原因，客户端安装的远程连接软件，版本与服务器端控制台接受的版本不兼容。第二种原因，服务器端的网络控制台里并没有启用远程连接协议，故无法接受远程连接请求。

嘿嘿 给以后的人做个参考
配置router0的f0/0端口ip
Router#configure terminal
Enter configuration commands, one per line End with CNTL/Z
Router(config)#interface f0/0
Router(config-if)#ip address 20010001 2552552550
Router(config-if)#no shutdown

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
Router(config-if)#exit

配置router0的f0/1端口ip
Router(config)#interface f0/1
Router(config-if)#ip address 20010011 2552552550
Router(config-if)#no shutdown
Router(config-if)#exit

配置router0s0/0/0端口ip
Router(config)#interface s0/0/0
Router(config-if)#ip address 20010021 2552552550
Router(config-if)#clock rate 500000
Router(config-if)#encapsulation hdlc
Router(config-if)#no shutdown

%LINK-5-CHANGED: Interface Serial0/0/0, changed state to down
Router(config-if)#exit

配置router1 s0/0/0端口ip
Router#configure terminal
Router(config)#interface s0/0/0
Router(config-if)#ip address 20010022 2552552550
Router(config-if)#clock rate 500000
Router(config-if)#encapsulation hdlc
Router(config-if)#no shutdown
%LINK-5-CHANGED: Interface Serial0/0/0, changed state to up
Router(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0/0, changed state to up

声明路由器router1的网络
Router(config)#router rip
Router(config-router)#network 20010020

声明路由器router0的网络
Router(config)#router rip
Router(config-router)#network 20010000
Router(config-router)#network 20010010
Router(config-router)#network 20010020

在router0上添加acl表

Router>en
Router#configure terminal
Enter configuration commands, one per line End with CNTL/Z
Router(config)#access-list 101 permit tcp any 200100080 0000 eq 80
Router(config)#access-list 101 permit tcp 20010012 0000 200100080 0000 eq 3389
Router(config)#access-list 101 permit tcp 20010012 0000 200100080 0000 eq 23
Router(config)#access-list 101 permit icmp 20010012 0000 200100080 0000
Router(config)#interface f0/0
Router(config-if)#ip access-group 101 out
Router(config-if)#exit
Router(config)#
