# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/local/bin:/usr/bin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the
# default value.

# If you want to change the port on a SELinux system, you have to tell
# SELinux about this change.
# semanage port -a -t ssh_port_t -p tcp #PORTNUMBER

在线等，急得很

GSSAPIAuthentication no

[苹果的小弟]

debug1: Authentications that can continue: publickey,password Permission denied, please try again. 还是一样的，网上的各种方法都试过了 有一种方法把UsePAM yes 改为 UsePAM no

[苹果的小弟]

改了后可以SSH登录，但是登录进去后，没有权限，什么su 、ps命令无法使用

[皇御雷霆]

AuthorizedKeysFile .ssh/authorized_keys
