讓Ubuntu Linux作業系統開啟Telnet服務
1.
sudo apt-get install xinetd telnetd
2. 安裝成功後,系統也會有相應提示:
sudo vi /etc/inetd.conf並加入以下一行
telnet stream tcp nowait telnetd /usr/sbin/tcpd /usr/sbin/in.telnetd
3. sudo vi /etc/xinetd.conf並加入以下內容:
# 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. sudo vi /etc/xinetd.d/telnet並加入以下內容:
# 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. 重啟機器或重啟網路服務sudo /etc/init.d/xinetd restart
6. 使用TELNET客戶端遠程登錄即可進行非root用戶訪問。
