CentOS6.5 Installing Telnet
1. Check if Telnet is installed[Email protected] ~]# Rpm-qa | grep telnet
2. Install Telnet and telnet-server[[email protected] ~]# yum install telnet[[email protected] ~]# Yum install Telnet-server
3, because after the installation of the Telnet service, the default is not to open the service, the following we need to modify the file to open the service. [[email protected] ~]# vi/etc/xinetd.d/telnet Modify Disable = yes disable = no service telnet
{
Flags = Reuse
Socket_type = Stream
wait = no
user = root
Server =/usr/sbin/in.telnetd
Log_on_failure + = USERID
Disable = no
}
4. Need to activate XINETD service[Email protected] ~]# service xinetd restart
stopping xinetd: [FAILED]
Starting xinetd: [OK]
[Email protected] ~]# service xinetd restart
stopping xinetd: [OK]
Starting xinetd: [OK]
5. Need to test whether Telnet is successfully opened
