Reverse HTTP Starter

  • The shareware Archive.Org "M-Azlan Software - Reverse HTTP Starter".
    • “Reverse HTTP Starter has many uses. Essentially, it connects the URL (http://...) of a text file and checks it for keywords at a specified interval. If a keyword is found a corresponding batch (*.bat) or executable (*.exe) file is run locally on your computer - usually to perform a certain task. If you want a certain application or script to be performed on a remote computer only when you desire, then all you need to do is upload a text file (i.e. a 'marker') to the URL and once this program checks it for your keyword the task will be run on your remote machine (the same one Reverse HTTP Starter is running on)”.
    • “A good example where this program comes in handy is when using an application such as VNC (Virtual Network Computing). If your workplace is behind a firewall and you need to control your work PC from home you will usually need to establish a 'reverse' connection for it to function. This means that the listening program runs on your home computer but the connection is initiated from your work PC. How are you going to initiate the connection if you're not at work? Just keep Reverse HTTP Starter running in your system tray at work and have it periodically (say every 180 seconds) check the URL for your marker (the text file with your keyword). When it finds the keyword it executes the batch file you have specified which in turn initiates the reverse connection. A detailed example is given in the Help section”.

Installation of TigerVNC on AlmaLinux

  • idroot "How To Install VNC Server on AlmaLinux 10".
  • $ sudo dnf update -y
$ sudo dnf upgrade -y
$ sudo dnf install epel-release
$ sudo dnf groupinstall "Development Tools" -y
$ sudo dnf install nano vim net-tools wget curl -y
  • Instead of ”$ sudo systemctl status systemd”:
    $ systemctl status
  • $ sudo systemctl status firewalld
  • Select one of the 2 desktops and install it, if necessary:
    • Installing GNOME Desktop
      $ sudo dnf groupinstall "Server with GUI" -y
sudo systemctl set-default graphical.target
    • Installation of Xfce
      $ sudo dnf groupinstall "Xfce" -y
$ sudo dnf groupinstall "Xfce" -y
  • Download and installation.
    • The package was available with RHEL9. With the release of RHEL10, the package was removed :-(.
      • ”$ sudo dnf install tigervnc-server tigervnc-server-module -y”.
    • After RHEL10 release: Manual download and manual local installation.
  • Confirm successful installation by checking installed package versions and verifying service file locations

vPro/AMT Resources

Selection Criteria for Computers with Intel iCore 5 / iCore7, internal Graphics Card, Intel vPro/AMT Technology

Motherboard
  • Must be shipped with vPro technology.
  • Must provide suitable AMT technology ( AMT 6 or newer ). Be aware of motherboards which provide vPro technology but insufficient AMT technology ( e.g. AMT 5 ).
CPU
  • The motherboard / computer must be shipped with a vPro enabled CPU :-). With many computers, the manufacturers provide optinal CPUs both with and without vPro, without explicte naming of the vPro feature.
  • The bundeling of a vPro CPU with a motherboard is no indictor that the motherboard supports vPro technology. Especially, the support of vPro technology is no indicator that there is sufficent AMT technology.
Your Questions to Motherboard Manufacuters and its Vendors
  • “Does your motherboard support Intel vPro Technology with AMT 6 or newer, with activated CPU-internal HD2000 / HD3000 Intel graphics card ?”.
  • “Definitely, may I address the switched-off computer by Ethernet network, and log on the internal AMT server and the VNC server?”.
Warning
  • There is the mission of Intel, to deliver the vPro technology just to the “system houses” and to the “business” sales channel ( → computers shipped with Windows Professional ), not to “consumer electronics supermarkets and consumer electronics store chains” and the “private users” channel ( → computers shipped with Windows Home Premium ).

Motherboards with vPro and AMT 6 or newer

Intel Desktop Boards Executive Series
  • Intel DQ57TML ( 1 serial Port via internal header, 1 x PS/2, floppy disk connector ), Intel DQ67OW ( No serial Port via internal header, 1 x PS/2, floppy disk connector, vPro, AMT 7.0, Geizhals.AT "DQ67OW" ), Intel DQ67EP, Intel DQ67SW ).
Asus
  • “ASUS P8Q67-M DO/CSM Motherboard” ( “1 x parallel port, 1 x COM port(s), 2x PS/2, 1 x internal speaker connector(s), vPro, AMT7. No floppy disk connector :-(. Geizhals.AT "P8Q67-M DO/CSM" ).
Foxconn
Gigabyte
Supermicro

Computers

Dell
  • Dell OptiPlex 755, Dell OptiPlex 760.
  • Dell OptiPlex 990 SF Advanced.
    • There is the rumour that you must order a special option in the online order formular, to activate vPro/AMT remote access, invoiced with 5 EUR. If you don´t do so, the rumour says that then you will get a computer without working remote access. Maybe it is not possible to order this option by the online order process ?! The option might appear in the section “BIOS Configuration Options” in the online order formular. Please contact me if you know what this option is, exactly.
  • Dell OptiPlex 990 SFF.
    • heise online, c't 23/2011 - “Prüfstand. Ferngelenkt. vPro-Rechner Dell OptiPlex 990 SFF. Dells Büro-PC Optiplex 990 Small Form Factor kombiniert die schnellste Sandy-Bridge-CPU mit einem kompakten Gehäuse und lässt sich auch aus der Ferne warten”.
Fujitsu
  • There is a rumour, that you must explicitely choose an order option to get a computer with activated vPro/AMT, invoiced with with 50 EUR .. 100 EUR, in 2012-03.
Lenovo Notebooks and Desktops with VPro
  • In 2014, I was told by Lenovo staff members, that the “T430”, “T440”, “T530”, “T540” ThinkPad notebooks and the “Think Centre M93p” desktop computer once could be ordered with i5-vpro and i7-vpro CPUs.
  • The chipset “Intel Q87 Chipset” enables the vPro technology!
  • Further, an Intel WLAN network component must be installed. With these special computers, the “Wake on LAN” ( WOL ) technology is then implemented, without further order.

Ultrabook Notebooks

  • EN.Wikipedia "Ultrabook", DE.Wikipedia "Ultrabook", usually with with 64 / 128 / 256 KB SDD.
  • Most sales of “Ultrabook” notebooks don't claim of AMT technology, i.e. they don't tell if the CPU is with or without Intel vPro, also no claim of AMT technology.

Zero Clients with VNC

  • The monitor with zero client “Fujitsu Technology Solutions GmbH - Zero Client DZ22-2” ( Geizhals.AT "DZ22-2" ).
  • The monitor with zero client “Technology Solutions GmbH Zero Client DZ19-2” ( Geizhals.AT "DZ19-2" ).
  • The USB stick “Fujitsu Technology Solutions GmbH -Portable Zero Client MZ900”.
