对运行在raspberry pi中的SSH服务器的访问被拒绝

我正在尝试从Ubuntu机器到pi进行ssh连接。我收到以下信息 命令：

debug1:SSH2\u MSG\u KEX\u DH\u GEX\u请求（1024所以解决方案有点直观。Pi和ubuntu系统之间的键盘布局不一样，因此在给出用户未知的密码时出错。
我有两个猜测。1是ssh服务器没有设置端口转发。将路由器上的端口22重定向到ras上的端口22pberry pi.2是因为提供的用户名不正确。它似乎使用pi作为登录用户名。您用来从pi内部连接到ssh服务器的命令是什么？1.您能给我一些端口转发方面的资源吗。我对此一无所知。2.“ssh-vv pi_ipaddress-l pi”我在所有系统中使用了相同的命令。没有任何更改。我不确定您使用的ip地址是内部ip地址还是外部ip地址。如果您从外部查看网络，即使有多个设备，也只有一个ip地址。这就是为什么需要端口转发，以便路由器知道发送inc的设备将消息发送到。但是，如果您使用内部ip地址，您应该能够连接到pi，而无需端口转发。从这里开始：从列表中选择您的路由器，它将逐步向您显示如何进行端口转发。检查服务器日志。应该有理由拒绝您的密码。但我猜您使用了
AllowUsers
和
sshd\u config
@TonyRuth中的类似选项：我只是浏览了链接。我没有使用任何路由器配置。Pi只是通过局域网与ubuntu系统进行对等连接。因此我认为这不会有任何问题。
