How Windows uses Telnet to manage virtual machine Linux

There are many tools for Linux remote login, such as PUTTY,SECURECRT ... In fact, with the help of the Windows Telnet tool, you can easily log on to the Linux system at the command prompt.

Although Telnet is simple, there are some configurations that you can use. The first thing to do is install the Telnet service on Linux, and second, open the Telent client in Windows. I use Linux is CentOS5.5, I personally feel a more stable version.

1. Turn on the Telnet service on Linux, first check whether Linux installs Telnet service, If TELNET-SERVER-0.17-39.E15 is displayed, it indicates that the Telnet service is installed on Linux, otherwise the telnet-server must be installed manually.

Installing Telnet requires xinetd-2.3.14-10.e15.i386.rpm, telnet-server-0.17-39.e15.rpm, and the system CD with both packages, using the RPM-IVH package Name can be installed.

To view the running status of Telnet and to turn on telent:

1) Use chkconfig telnet--list to view the Telnet run status

2) Use chkconfig telnet on to turn on the Telnet server

CentOS5.5 only open the SSH port by default, and Telnet uses 23 port, to open the port, you need to modify/etc/sysconfig/iptables, add -A rh-firewall-1-input-m State-- State new-m tcp-p TCP--dport 23-j ACCEPT last reboot iptables, service iptables restart (or direct restart of system s)

(This step is not required if the firewall is not turned on)

　　　　

　　　　　　　　

2. Start the Telnet client on Windows

Control Panel, programs and features, turn on or turn off Windows features, check the Telnet client

　　　　　　　　

　　　　　　　　

After the configuration is complete, you can use Telnet to check the results. Enter telnet linux host IP at the command prompt
