  • SSH测试远程服务器端口的连通性

    ssh是linux的标准配置并且最常用,可以用来判断端口是否打开

    用法: ssh -v -p port username@ip

    -v 详细模式(会打印日志,显示登录的细节).
    -p 指定端口

    username 可以随意
    ip 待测试机器的ip

    --------------------------------------------------------------------------------------------------------

    pipci@HP:~$ ssh -v -p 111 dd@10.10.10.6
    OpenSSH_7.6p1 Ubuntu-4ubuntu0.3, OpenSSL 1.0.2n 7 Dec 2017
    debug1: Reading configuration data /etc/ssh/ssh_config
    debug1: /etc/ssh/ssh_config line 19: Applying options for *
    debug1: Connecting to 10.10.10.6 [10.10.10.6] port 111.
    debug1: Connection established.                           ##出现Connection established表示建立连接,也就代表着这个端口开放
    debug1: key_load_public: No such file or directory
    debug1: identity file /home/pipci/.ssh/id_rsa type -1
    省略

    pipci@HP:~$ ssh -v -p 222 dd@10.10.10.6
    OpenSSH_7.6p1 Ubuntu-4ubuntu0.3, OpenSSL 1.0.2n 7 Dec 2017
    debug1: Reading configuration data /etc/ssh/ssh_config
    debug1: /etc/ssh/ssh_config line 19: Applying options for *

    debug1: connect to address 10.10.10.6 port 222: Connection refused
    ssh: connect to host 10.10.10.6 port 222: Connection refused          ##出现Connection refused表示连接拒绝,也就代表着这个端口关闭
    pipci@HP:~$
