我在两台 Linux 主机之间设置了 SSH 无密码访问。但无密码访问不起作用。身份验证被取消，并显示拒绝消息，如下所示
su - wsync
-bash-4.1$ ssh node-x3
debug1: Authentication succeeded (publickey).
debug1: channel 0: new [client-session]
debug1: Requesting [email protected]
debug1: Entering interactive session.
debug1: Sending environment.

/var/log/secure在目标主机上可以看到以下内容
Jul 1 18:49:23 syd-fs-x3 sshd[17261]: pam_unix(sshd:session): session opened for user wsync by (uid=0)
Jul 1 18:49:23 syd-fs-x3 sshd[17266]: error: open /dev/tty failed - could not set controlling tty: Permission denied

Jul 1 18:49:24 syd-fs-x3 sshd[17261]: pam_unix(sshd:session): session closed for user wsync
wsync用户在目标主机上处于 chroot 状态
-bash-4.1$ pwd
/home/chroot/home/wsync
$ ls -l /home/chroot/dev/tty
crw-rw-rw- 1 root root 5, 0 Nov 30 2015 /home/chroot/dev/tty
wsync以下是目标主机上用户的设置。
$ sudo grep -A 2 wsync /etc/ssh/sshd_config
Match User wsync
ChrootDirectory /home/chroot
ForceCommand /home/bin/validate-rsync.sh
/etc/securetty按要求输出
$ sudo grep tty /etc/securetty
tty1
tty2
tty3
tty4
tty5
tty6
tty7
tty8
tty9
tty10
tty11
请让我知道是什么问题？
