如何为 Ubuntu 服务器 18.04 启用并发远程会话？

我已经安装了 xrdp 远程会话工具。
但我最多只能在远程会话中接收 4 个用户。
当我尝试在远程会话中接收第 5 个用户时，现有的一个用户被终止。
实际上，我们想在远程会话中访问 75 个以上的用户。我如何在我们的服务器中配置并发远程会话。
下面提到的sesman.ini配置文件

[Globals]
ListenAddress=127.0.0.1
ListenPort=3350
EnableUserWindowManager=true
UserWindowManager=startwm.sh
DefaultWindowManager=startwm.sh

[Security]
AllowRootLogin=true
MaxLoginRetry=4
TerminalServerUsers=tsusers
TerminalServerAdmins=tsadmins
; When AlwaysGroupCheck=false access will be permitted
; if the group TerminalServerUsers is not defined.
AlwaysGroupCheck=false

[Sessions]
;; X11DisplayOffset - x11 display number offset
; Type: integer
; Default: 10
X11DisplayOffset=10

;; MaxSessions - maximum number of connections to an xrdp server
; Type: integer
; Default: 0
MaxSessions=50

;; KillDisconnected - kill disconnected sessions
; Type: boolean
; Default: false
; if 1, true, or yes, kill session after 60 seconds
KillDisconnected=false

;; DisconnectedTimeLimit - when to kill idle sessions
; Type: integer
; Default: 0
; if not zero, the seconds before a disconnected session is killed
; min 60 seconds
DisconnectedTimeLimit=0

;; Policy - session allocation policy
; Type: enum [ "Default" | "UBD" | "UBI" | "UBC" | "UBDI" | "UBDC" ]
; Default: Xrdp:<User,BitPerPixel> and Xvnc:<User,BitPerPixel,DisplaySize>
; "UBD" session per <User,BitPerPixel,DisplaySize>
; "UBI" session per <User,BitPerPixel,IPAddr>
; "UBC" session per <User,BitPerPixel,Connection>
; "UBDI" session per <User,BitPerPixel,DisplaySize,IPAddr>
; "UBDC" session per <User,BitPerPixel,DisplaySize,Connection>
Policy=Default

[Logging]
LogFile=xrdp-sesman.log
LogLevel=DEBUG
EnableSyslog=1
SyslogLevel=DEBUG

;
; Session definitions - startup command-line parameters for each session type
;

[Xorg]
; Specify the path of non-suid Xorg executable. It might differ depending
; on your distribution and version. The typical path is shown as follows:
;
; Fedora 26 or later    :  param=/usr/libexec/Xorg
; Debian 9 or later     :  param=/usr/lib/xorg/Xorg
; Ubuntu 16.04 or later :  param=/usr/lib/xorg/Xorg
; Arch Linux            :  param=/usr/bin/Xorg or param=Xorg
; CentOS 7              :  param=/usr/bin/Xorg or param=Xorg
;
param=/usr/lib/xorg/Xorg
; Leave the rest paramaters as-is unless you understand what will happen.
param=-config
param=xrdp/xorg.conf
param=-noreset
param=-nolisten
param=tcp
param=-logfile
param=.xorgxrdp.%s.log

[Xvnc]
param=Xvnc
param=-bs
param=-nolisten
param=tcp
param=-localhost
param=-dpi
param=96

[Chansrv]
; drive redirection, defaults to xrdp_client if not set
FuseMountName=thinclient_drives

[SessionVariables]
PULSE_SCRIPT=/etc/xrdp/pulse/default.pa

只是一个想法...您可能想检查以下文件中是否定义了一些限制

/etc/security/limits.conf

如果您将 maxlogins 值设置为小于您的连接数，那么这可能是您的问题......

将此值调整为更高的值应该允许您执行更多的连接....

再说一遍，这只是一个想法......

希望这能有所帮助，下次见
