OpenSSH_5.1p1 pam_chroot for debian

[訪客]

請問一下各位,為何我在/var/log/auth.log

會看到這些

Nov 25 12:37:11 xxxxx pam_chroot[16469]: session: reading config file (/etc/security/chroot.conf)
Nov 25 12:37:11 xxxxx pam_chroot[16469]: session: expanded path "/var/chroot/sshd" -> "/var/chroot/sshd"
Nov 25 12:37:11 xxxxx pam_chroot[16469]: session: found chroot_dir "/var/chroot/sshd" for user "orange"
Nov 25 12:37:11 xxxxx pam_chroot[16469]: session: preparing to chroot()

然後,在ssh login 的時候就斷線了,我是想作個限制login 目錄

/etc/security/chroot.conf 目錄
orange /var/chroot/sshd
=====================================

/etc/pam.d/sshd

session required pam_chroot.so debug
=====================================
/etc/pam.d/login

session required pam_chroot.so debug

/var/chroot/sshd
