以下步骤为搭建sftp步骤
[root@station28 ssh]# mkdir /home/sftpserver
[root@station28 ssh]# useradd -d /home/sftpserver -s /bin/false test01 //创建用户，指定shell为/bin/false
useradd: warning: the home directory already exists.
Not copying any file from skel directory into it.
[root@station28 ssh]# passwd test01
Changing password for user test01.
New UNIX password:
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:
passwd: all authentication tokens updated successfully.

[root@station28 ssh]# pwd
/etc/ssh
[root@station28 ssh]# cp sshd_config  sshd_config_1114.bak
sshd_config配置如下
# Authentication: //在Authentication下加入如下两行，指定可以登入的网段
AllowUsers *@192.168.*.*
AllowUsers *@127.0.0.1
# override default of no subsystems
#Subsystem      sftp    /usr/local/ssh/libexec/sftp-server //将这行注释，使用internal-sftp,添加如下行
Subsystem       sftp    internal-sftp

# Example of overriding settings on a per-user basis
#Match User anoncvs
#       X11Forwarding no
#       AllowTcpForwarding no
#       ForceCommand cvs server
//在最下面添加如下行，对test01这个用户chroot到/home/sftpserver目录下
Match User test01
        X11Forwarding no
        AllowTcpForwarding no
        ForceCommand internal-sftp
        ChrootDirectory /home/sftpserver
[root@station28 ssh]# sftp test01@192.168.14.28//chroot成功
test01@192.168.14.28'spassword:
Connected to 192.168.14.28.
