Debian Linux系统如何配置Telnet服务
时间：2014-04-05 来源：服务器之家 投稿：root
步骤：
1. debian:~# apt-get install telnetd
debian:~# apt-get install telnetd-ssl
debian:~# apt-get install xinetd
（安装包xinetd……）
2. 新建一个文件/etc/xinetd.d/telnet,方法及内容如下，并保存.
debian:~# nano -w /etc/xinetd.d/telnet
GNU nano 1.2.4 File: /etc/xinetd.d/telnet
# 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
server_args = -h
log_on_failure += USERID
}
3. debian:~# apt-get install telnet
(安装包telnet……)
4. 尝试连接：
debian:~# telnet 10.11.12.13（本机IP）
结果：
Trying 10.11.12.13...
Connected to 10.11.12.13.
Escape character is '^]'.

如果想启用root登陆，做法如下：
debian:~# vim /etc/pam.d/login
把该行 auth requisite pam_securetty.so 注释掉即可，配置完毕。
命令：
debian:~# /etc/init.d/xinetd （命令）
force-reload(强制刷新)|reload（刷新）|restart（重启）|start（启动）|stop（关闭）
其余的自己看到办
