ssh 权限被拒绝()

Question

我正在尝试ssh user@ip-address但出现Permission denied ()错误。

之前我曾Permission denied (publickey,password)将 更改为ssh_config和PasswordAuthetification=no，sshd_config PubkeyAuthentication=no但权限被拒绝的情况仍然存在。

sshd_config：

StrictModes no
PubkeyAuthentication no
AllowTcpForwarding yes
GatewayPorts yes
X11Forwarding yes
PrintMotd no
TCPKeepAlive yes
AllowUsers user

# Allow client to pass locale environment variables
AcceptEnv LANG LC_*

# override default of no subsystems
Subsystem       sftp    /usr/lib/openssh/sftp-server

ssh_config：

Host *
ForwardX11Trusted yes
PasswordAuthentication no
Protocol 2

ssh -v user@ipadress：
