嵌入式ftp和telnet环境搭建

来源：互联网发布：福禄克网络sn查询编辑：程序博客网时间：2024/06/08 05:48

=========================vsftpd==========================================
1.安装 vsftpd
apt-get install vsftpd

2.配置 vsftpd.conf
vi /etc/vsftpd.conf (可以参考我的另一篇配置文件详解)

3.ftp路径配置
打开passwd
vi /etc/passwd
找到ftp开头的我的是ftp:x:105:110:ftp daemon,,,:/srv/ftp:/bin/false
其中/srv/ftp为目录可以修改

修改权限主目录为755 内容777

chmod 775 /srv/ftp   /* 修改自己的 */
chmod 777 /srv/ftp/* -R   /* ftp下有资源的时候 */
重启服务
service vsftpd restart
=========================telnet==========================================
1.安装服务
apt-get install telnetd
apt-get install telnetd-ssl
apt-get install xinetd
新建一个文件/etc/xinetd.d/telnet,内容如下，并保存
vi /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
}
本来因为telnet是明文传输的，所以处于安全考虑才限制了root从telnet登陆，如果你需要使用，那么如下修改
vi /etc/pam.d/login
#把下面在行注释掉
# auth       requisite pam_securetty.so
打开配置文件：vi /etc/securetty；在文件末尾添加pts/0
重启服务
service xinetd restart

PC端
sudo telnet 192.168.1.114
