    我们把实验的命令写到文本:
    基本配置:
    r1:
    en
    conf t
    host r1
    enable pass cisco
    line vty 0 4
    pass cisco
    login
    exit
    int s0/0
    ip addr 192.168.1.1 255.255.255.0
    no shut
    clock rate 64000
    exit
    router rip
    ver 2
    no auto-summary
    network 192.168.1.0
    exit
    r2:
    en
    conf t
    host r2
    enable pass cisco
    line vty 0 4
    pass cisco
    login
    exit
    int s0/0
    ip addr 192.168.1.2 255.255.255.0
    no shut
    int s0/1
    ip addr 192.168.2.1 255.255.255.0
    no shut
    clock rate 64000
    exit
    router rip
    ver 2
    no auto-summary
    network 192.168.1.0
    network 192.168.2.0
    exit
    r3:
    en
    conf t
    host r3
    enable pass cisco
    line vty 0 4
    pass cisco
    login
    exit
    int s0/1
    ip addr 192.168.2.2 255.255.255.0
    no shut
    exit
    router rip
    ver 2
    no auto-summary
    network 192.168.2.0
    exit
    在r2上配置拒绝telnet:
    conf t
    access-list 101 deny tcp 192.168.1.1 0.0.0.0 192.168.2.0 0.0.0.255 eq telnet
    access-list 101 permit ip any any
    int s0/1
    ip access-group 100 out
    exit
    access-list 102 deny tcp 192.168.1.1 0.0.0.0 192.168.2.0 0.0.0.255 eq ftp
    access-list 102 permit ip any any
    int s0/1
    ip access-group 100 out
    exit
    access-list 103 deny icmp 192.168.4.2 0.0.0.0 192.168.1.0 0.0.0.255 echo
    access-list 103 deny icmp 192.168.4.2 0.0.0.0 192.168.1.0 0.0.0.255 echo-reply
    access-list 103 permit ip any any
    int s0/0
    ip access-group 101 out
    写完了以后我们开始粘贴。

控制访问列表(ACCESS LIST) 
    粘贴完并没有错误,我们先不添加访问控制列表看能否telnet
    没有问题可以telnet并打开了

控制访问列表(ACCESS LIST) 
    我们来添加访问列表

控制访问列表(ACCESS LIST) 
    在来telnet 如果失败了,我们就成功了。

控制访问列表(ACCESS LIST) 
    telnet不上了,成功!!!!!!
    凌晨了睡觉喽!!!!!!呵呵 !!!!!!

What are the benefits of multithreading in c#? What are the benefits of multithreading in c#? Apr 03, 2025 pm 02:51 PM

The advantage of multithreading is that it can improve performance and resource utilization, especially for processing large amounts of data or performing time-consuming operations. It allows multiple tasks to be performed simultaneously, improving efficiency. However, too many threads can lead to performance degradation, so you need to carefully select the number of threads based on the number of CPU cores and task characteristics. In addition, multi-threaded programming involves challenges such as deadlock and race conditions, which need to be solved using synchronization mechanisms, and requires solid knowledge of concurrent programming, weighing the pros and cons and using them with caution.
