2、配置文件(若文件不存在就手动添加文件和相应配置信息)
1): #:~$ vi /etc/inetd.conf 添加下面一行信息
telnet stream tcp nowait telnetd /usr/sbin/tcpd /usr/sbin/in.telnetd
2): #:~$ vi /etc/xinetd.conf 修改下面红色标注部分的信息

# Some defaults, and include /etc/xinetd.d/
defaults
{
# Please note that you need a log_type line to be able to use log_on_success
# and log_on_failure. The default is the following :
# log_type = SYSLOG daemon info(插入红色部分)
instances = 60
log_type = SYSLOG authpriv
log_on_success = HOST PID
log_on_failure = HOST
cps = 25 30
}
includedir /etc/xinetd.d
3): #:~$ vi /etc/xinetd.d/telnet 修改下面红色标注部分的信息
# default: on
# description: The telnet server serves telnet sessions; it uses \
# unencrypted username/password pairs for authentication.
service telnet
{
disable = no
flags = REUSE
