XRDP 拒绝登录

Question

我在 Windows 7 计算机上尝试通过 Windows 远程桌面访问 RHEL7 系统。

直到今天，我（以及我部门的其他人）都能够使用 xrdp 登录到 RHEL 机器。

今天突然 xrdp 开始拒绝连接。我可以看到绿色背景登录屏幕，但它拒绝凭据（这些都很好）。

我可以 ping 到服务器，通过 putty 连接并使用 filezilla，但远程桌面连接拒绝会话登录。

我还尝试通过远程桌面连接到另一台 CENTOS 机器，它工作正常。

有任何想法吗？

我确实遇到了同样的问题，这就是我解决的方法，但我对解决方案并不满意。

您需要将sesmain.in和sesman.ini中的字段更改MaxSessions为比已有的数字更大的数字。似乎有些会话没有以正确的方式释放。两个文件都在/etc/xrdp. 您需要 sudo 权限才能编辑它们。
