安装脚本

#!/bin/sh
echo "[i] Updating and upgrading Kali (this will take a while)"
apt-get update
apt-get full-upgrade -y

echo "[i] Installing Xfce4 & xrdp (this will take a while as well)"
apt-get install -y kali-desktop-xfce xorg xrdp

echo "[i] Configuring xrdp to listen to port 3390 (but not starting the service)"
sed -i 's/port=3389/port=3390/g' /etc/xrdp/xrdp.ini

安装后重启xrdp

sudo systemctl start xrdp
sudo systemctl enable xrdp

远程桌面端口是3390，不是3389，如果使用远程桌面时出现闪退现象，要在使用远程桌面连接之前，从界面上logout
