ubuntu 下telnet服务配置

1，安装服务apt-get install xinetd telnetd.

2,安装成功后编辑/etc/inetd.conf文件,
# Simple configuration file for xinetd
#
# Some defaults, and include /etc/xinetd.d/
defaults
{

    instances = 60
    log_type = SYSLOG authpriv
    log_on_success = HOST PID
    log_on_failure = HOST
    cps = 25 30
}
includedir /etc/xinetd.d
3，修改文件/etc/xinetd.d/telnet文件：

# default: on
# description: The telnet server serves telnet sessions; it uses \
# unencrypted username/password pairs for authentication.
service telnet
{
    disable = no
    flags = REUSE
    socket_type = stream
    wait = no
    user = root
    server = /usr/sbin/in.telnetd
    log_on_failure += USERID
}
4，重启telnet服务：/etc/init.d/xinetd restart。
5，查看当前网络状态：netstat -tnlup,查看端口号23状态为LISTEN则telnet服务即被开启。
