问一下 Linux 环境下 rdp 连接 Windows 的问题。求各位大佬指点

[teliang]

公司的生产数据库只能通过远程 Windows，然后在 Windows 上面操作。 但是我用 Linux 怎么都连不上，网上搜了一下好像我也搞不定，求各位大佬指点

环境是 Ubuntu 20.04.3 LTS

xfreerdp /u:userName /p:passwd /v:ip:port /relax-order-checks +glyph-cache

错误与如下：

😮‍💨连接个远程真难啊，求各位大佬指导指导

[Puteulanus]

要不试试 Docker 起个 Apache Guacamole，支持 RDP 和 VNC

[teliang]

@Puteulanus 堡垒机这块是领导弄的，要弄新的有点麻烦

[clino]

我用的客户端是 remmina ,长期使用，除了使用 256 色连接桌面进程会挂住，其他没碰到太多问题，推荐一下

[teliang]

@clino 我用 remmina 也连不上，remmina 使用 rdp 其实也是用的 freerdp 吧

[Puteulanus]

@teliang 唔，我的意思是本地起一个当成 RDP 客户端用，如果 Linux 下 RDP 实在难弄，可以作为一个备选方案

[teliang]

@Puteulanus 噢噢，我了解一下，这我还真没用过，感谢

[Puteulanus]

@teliang 小众软件之前推荐过一个基于它的 https://www.appinn.com/next-terminal/ 看起来更方便起一点

[clino]

@teliang 那 rdesktop 试过了吗？

[teliang]

@clino 刚试了一下，也不行，日志是这样的：
```bash
Do you trust this certificate (yes/no)? yes
Connection established using SSL.
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 53 (X_CreatePixmap)
Value in failed request: 0x0
Serial number of failed request: 85
Current serial number in output stream: 307

```

[clino]

找一个 PC 上的 windows 开启远程桌面能连上吗？

[teliang]

@clino Windows 相同的账号密码可以连上

[fox0001]

我也是长期使用 remmina，连上公司的 Windows 服务器。

[silkriver]

我用 remmina 没有问题，可以试试装 remmina-plugin-rdesktop 据说更可靠
https://wiki.archlinux.org/title/Remmina_(%E7%AE%80%E4%BD%93%E4%B8%AD%E6%96%87)

[clino]

@teliang 我是说找一台 PC 上的 windows 测试一下，是你本地客户端的问题，还是客户端能连一般的 windows，只是不兼容服务器上的 windows 。

[kkk123]

[ERROR][com.freerdp.core.update] - SECONDARY ORDER [0x03] Cache Glyph failed

是不是开了 Glyph Cache , 这个在 remmina 是默认不选的。

[teliang]

@kkk123 不加+glyph-cache 是这个错。

[teliang]

@clino 额，我用 pc 上的 windows 是可以连到远程服务器的，Linux 连不上

[clino]

@teliang 我的 ubuntu 也是 20.04 ，但是长期连 PC windows 都没问题，你测过连非服务器的吗？就连一般的 PC windows 。

[teliang]

@clino 我装了个 Windows 虚拟机试了一下，Ubuntu 可以远程到虚拟机上，虚拟机也可以远程连接到服务器，但是 Ubuntu 连不到服务器。。。

[clino]

那看来就是 ubuntu 的 rpd 客户端和你服务器上的 windows 不兼容了.
