我刚买了一个Huion H640P 平板电脑（只是为了写笔记），并将它与内核 5.3.0-40-generic 的 Ubuntu 18.04 一起使用。
我安装了digimend-kernel-drivers v9以使平板电脑工作。
现在，如何在平板电脑上配置热键并使配置永久化，这样我就不必启动以下命令：
xsetwacom set "HID 256c:006d Pad pad" button 1 key Ctrl z
每次我启动 Ubuntu？（例如，我想将按钮 2 设置为滚动）。
我遇到了以下问题：我正在尝试使用带有 Kerberos 身份验证的 SSH 从客户端 VM 连接到服务器 VM，但 SSH 仍然要求我输入密码。显然，我/etc/ssh/sshd_config在服务器端修改了文件以启用：GSSAPIAuthentication yes和GSSAPICleanupCredentials yes. 在客户端机器上，我在/etc/ssh/ssh_config文件中做了同样的事情。关于 Kerberos：我使用 kadmin.local 添加了一个主体，称为host/[email protected]其中“server”是服务器机器的主机名，SERVER.COM 是领域的名称。为 SSH 服务创建该主体后，我使用ktadd -k command添加位于/etc/krb5.keytab. 的输出sudo klist -ke /etc/krb5.keytab是
Keytab name: FILE:/etc/krb5.keytab
KVNO Principal
---- --------------------------------------------------------------------------
1 host/[email protected] (aes256-cts-hmac-sha1-96)
1 host/[email protected] (aes128-cts-hmac-sha1-96)
1 host/[email protected] (aes256-cts-hmac-sha1-96)

所以，keytab的创建就OK了。好吧，在服务器机器上，我还添加了一个名为 michele 的用户（甚至在上面的列表中列出并显然添加为主体），并且在客户端机器上创建了相同的用户。sudo /usr/sbin/sshd -p 9001 -D -dd 我在客户端和服务器上都以调试模式键入了 ssh 命令，得到以下信息：

从客户端来看，似乎存在有关凭据的 GSSAPI 失败。我想在不输入密码的情况下在我的服务器中进行 ssh。你能帮我吗？谢谢！
在 VirtualBox 中安装了两个虚拟机后，我尝试使用 ssh 协议从客户端机器（安装了 openssh-client）连接到 ssh 服务器机器（安装了 openssh-server）。两台机器都在一个仅主机网络中（名为：vboxnet0）。当我尝试从客户端（名称：sshclient）打开服务器上的 ssh 连接（名称：sshserver 和 IP 地址：192.168.56.3）时，我收到消息：权限被拒绝，请重试。我输入了：ssh sshclient@sshserver -p 22并输入了密码（我确定是正确的）3 次。服务器配置文件中启用了 22 端口/etc/ssh/sshd_config，PasswordAuthentication 行被取消注释，并且客户端的 IP 地址被添加到/etc/hosts服务器端的文件中。
发生了什么？有什么技巧可以解决吗？
非常感谢。
