报错

Trying 127.0.0.1… telnet: Unable to connect to remote host: Connection refused

$ netstat -tnl

查看端口状态。 可以看到没有进程在监听本地的23端口,说明本地的telnet服务没有启动。

解决方法 1、安装xinetd和telnetd $ sudo apt-get install xinetd telnetd

2、创建文件 $ sudo vim /etc/inetd.conf 并加入以下一行

telnet stream tcp nowait telnetd /usr/sbin/tcpd/usr/sbin/in.telnetd

3、修改文件/etc/xinetd.conf $ sudo vi /etc/xinetd.conf 并修改为以下内容

# Simple configuration file for xinetd # # 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 instances = 60 log_type = SYSLOG authpriv log_on_success = HOST PID log_on_failure = HOST cps = 25 30 } includedir /etc/xinetd.d

4、创建文件/etc/xinetd.d/telnet $ sudo vi /etc/xinetd.d/telnet 并输入以下内容

# 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 }

5、重启系统,查看端口状态 $ netstat -tnl 可以看到正在监听23端口 6、最后测试远程登录本地 $ telnet 127.0.0.1
