SSHD使用Subsystem sftp internal-sftp进行设置
RSSH将用户指定为只能使用scp和sftp
用户的帐户正在使用/usr/bin/RSSh作为shell和/ home / user / public_html
用户的主目录是root：用户所有者：组

我注意到,他们可以查看他们可以查看的内容和目录的唯一文件都是世界可读的,这是有道理的,但为什么他们允许他们离开他们的目录呢？请不要说我只是回答了我自己的问题.目的是找到防止这种情况的最佳实践解决方案.

期望的结果是它们被限制为cd到任何不属于它们的目录的能力.

我在这里错过了什么吗？

这是RSSh.conf文件的内容;

logfacility = LOG_USER

allowscp
allowsftp
#allowcvs
#allowrdist
#allowrsync
#allowsvnserve

# set the default umask
umask = 022

user=wwwtest1:077:110000:/home/wwwtest1/public_html

这是sshd_config文件的内容;

# Set this to 'yes' to enable PAM authentication,account processing,# and session processing. If this is enabled,PAM authentication will
# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication.  Depending on your PAM configuration,# PAM authentication via ChallengeResponseAuthentication may bypass
# the setting of "PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without
# PAM authentication,then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.
UsePAM yes
