腻子，SSH“访问被拒绝”

Question

我的 SSH 有问题，我在 windows 机器上使用 putty。

我在另一台装有 ubuntu 17.10 的 Windows 机器上有一个虚拟机（VirtualBox）。

我可以从一台机器 ping 到另一台机器，但 IP 不同 虚拟机我设置了一个 Bridge 连接。

我从两台机器的防火墙中打开了 22 端口。

Putty 连接时会显示一条消息“登录为：@192.168.0.148 的密码：”

当我输入密码时，它会提示我“访问被拒绝”

我尝试更改腻子设置，例如... SSH-->Auth-->GSSAPI--->Attempt GSSAPI authetication (SSH-2 only)remove the check.

我尝试编辑 ubuntu 文件“sshd_config”#PermitRootLogin 是

我附上了 SSDSconfig 文件和 putty 日志

文件SSDH：

#$OpenBSD: sshd_config,v 1.101 2017/03/14 07:19:07 djm Exp $
# This is the sshd server system-wide configuration file.  See

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

# 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.

如果我没记错的话，在服务器地址字段中的腻子上只需添加 @... 似乎还有自动登录选项，但我从未尝试过：electrictoolbox.com/specifying-auto-login-name-putty
