Bash Script for Linux to Connect to Microsoft VDI

Script by Dino9021

因為 Remmina 一定要記住 User Name & Password 才能連線
有安全上的疑慮, 因此利用 Bash Script 搭配 xfreerdp 來進行連線作業

需要將連線資源寫成文字檔放在 Web Server 上讓 Bash Script 去下載解讀
如此如果資源有異動, 就不需要去 Client 更換 Script, 只要修改 Web Server 上的資源檔案就行了
而且如此一來不需要安裝 Remmina, 只要有 xfreerdp 就可以用了
經過測試, 如果不裝 Remmina 的話 xfreerdp 無法裝到 2.0 以上版本 (才支援 RDG)

安裝時參考 Microsoft 2012 R2 VDI 攻略 中 ubuntu 的安裝方法

• Install Remmina and FreeRDP to Connect to VDI Through RD Gateway
• sudo apt-get update
• sudo apt-get dist-upgrade
• sudo apt-add-repository ppa:remmina-ppa-team/remmina-next
• sudo apt-get update
• sudo apt-get install freerdp-x11 remmina remmina-plugin-rdp
• sudo apt-get upgrade
• xfreerdp --version

連線參數有需要可以自己改

# Logon Domain.com;RDCB Server FQDN;RDGateway FQDN;

# Menu_Workstation.txt for VM Base, Multi-Line

# Collection Name;Desc;Load Balance Info;
