史上最强一键登录Citrix Gateway远程桌面VM【原创】

• No resident app needed, no resource require after connected, no garbage file left(.rdp files)
• One-Click to connect to remote VM, fast, simple, easy
• Enable change multi-monitor settings, you can force single monitor or dual monitor for remote desktop
• Self-signed certification supported
• Reduce Citrix gateway web portal resource usage

• 一键连接Citrix远程桌面
• 支持自签名证书，见 my.pem，你可以自己转换 Citrix 登录时的证书为 PEM 格式，PFX证书转 PEM 格式，指令如下：
  
  openssl pkcs12 -in yourfile.pfx -out yourfile.pem -nodes
• 支持强制多显示器、双显示器支持
• 没有内存驻留程序，零资源消耗，无垃圾文件(.rdp文件)产生
• 无需第三方软件支持，只需要Bash支持即可，可以使用git bash或者wsl，也可以使用Mingw等Bash环境
• 降低Citrix网关的服务器压力
