CentOS下怎麼退出telnet

CentOS下怎麼退出telnet

在調試一個網路程式時遇到問題，服務啟動了，用戶端卻串連不上；首先就想到了用telnet串連看看；

命令和Windows下一樣，telnet IP 連接埠號碼

 

# telnet 192.168.0.107 1111

Trying 192.168.0.107...telnet: connect to address 192.168.0.107: Connection timed out

連線逾時了，估計是Windows防火牆的問題，我的服務是跑在Windows上的；

 

控制台》系統安全》Windows防火牆》進階設定》建立入站規則；

再執行telnet命令看看，

 

Trying 192.168.1.107...Connected to 192.168.1.107.Escape character is '^]'.

串連成功，果然是防火牆的問題！

 

 

誒[éi],怎麼回事! 退不出去了！Ctrl + c，Ctrl + z，ESC，q，quit，exit，都不行；

注意telnet串連成功後輸出的資訊：

 

Escape character is '^]'.

Ctrl + ]

 

姿勢終於對了；

 

telnet> ?Commands may be abbreviated.  Commands are:close   close current connectionlogout  forcibly logout remote user and close the connectiondisplay display operating parametersmode    try to enter line or character mode ('mode ?' for more)open    connect to a sitequit    exit telnetsend    transmit special characters ('send ?' for more)set     set operating parameters ('set ?' for more)unset   unset operating parameters ('unset ?' for more)status  print status informationtoggle  toggle operating parameters ('toggle ?' for more)slc     change state of special charaters ('slc ?' for more)z       suspend telnet!       invoke a subshellenviron change environment variables ('environ ?' for more)?       print help informationtelnet> closeConnection closed.

輸入問號然後斷行符號，可以查看協助；

 

輸入close或quit然後斷行符號，可以退出telnet；
