ubuntu开启telnet服务

1. sudo apt-get install xinetd telnetd

　　2. 安装成功后，系统也会有相应提示（好象7.10才有，6.10就没看到）

　　sudo vi /etc/inetd.conf并加入以下一行

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

　　3. sudo vi /etc/xinetd.conf并加入以下内容：

1 2 3 4 5 6 7 8 9 10 11 12 13 14

# 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. sudo vi /etc/xinetd.d/telnet并加入以下内容：

1 2 3 4 5 6 7 8 9 10 11 12 13

# 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. 重启机器或重启网络服务sudo /etc/init.d/xinetd restart

　　6. 使用TELNET客户端远程登录；

　　ifconfig -a　　//// 显示本机地址。
