How to share your Windows local drives via Remote Desktop (RDP) – Safe file copy with RDP protocol

Tuesday, October 14th, 2014

remote-desktop-connection-options-button-screenshot

Just had a task to install Tomcat 7, Java JRE 1.7 and .NET Framework 3.5 and MS Visual C++ x86 on a Windows 2008 RC2 system situated behind a firewalled network NAT. To do the installation I had to use a special jump host (which was also a MS Windows system). The end system where installation had to occur did not have access to the Internet was in special DMZ-ed network so to install above 3 software packages I had to transfer them from my notebook to install host.
To depic what had to happen, I had to:

Transfer files from (host A – my notebook) -> via host (B – jump host) to host (C – the end install host).

Default Windows RDP Client command (mstsc.exe) supports transferring files between host A and RDP-ed host B via standard file copy / paste, so I tried transferring files between my work Windows PC to (jump host B), by copy pasting the files, but as the DotNetFx35Client.exe file was 261 Megabytes and the network between host A and B has some shapings and network firewalls the file transfer timed out. Copy / Paste method via RDP Protocol by default, doesn’t support Transfer Resume thus in order to transfer the 261 MB file, I tried Sharing C:Temp Folder and transfer that way, but unfortunately I didn’t have the permissions in that Windows Domain to create sharings (even though on the remote system I was already logged in with admin accounts). I’ve consulted a colleague on advise on how to transfer the files and I was told about a Win RDP client option to share drives.

Here is how to share your PC drive letters C: D: E: etc. via Remote Desktop Protocol


1. Run mstsc.exe

2. Click the Options button

3. Click Local Resources tab

4. Click More button

5. Click on Drives

remote-desktop-connection-share-windows-disk-drives-option-screenshot

Then after connecting to the Remote RDP host, all your local PC drive partitions C: D: E: will be visible as (attached) ones in mounted in My Computer / MS Explorer with assigned new drive letters

Once, I transferred the .NET Framework 3.5 while using the installer I was notified that .NET Framework 3.5 is by default included in Windows 8 and I need only to enable it.

To enable .NET Framework 3.5 in Windows 8 from Control Panel

Choose Programs, and then choose Turn Windows features on or off.

Select the .NET Framework 3.5 (includes .NET 2.0 and 3.0) check box.

Quick shortcut to lock your Linux computer desktop (Few words on Linux screensavers)

Thursday, November 20th, 2014

quick-way-to-lock-desktop-linux-howto-key
Locking the PC while going for a coffee break, Lunch or toilet is longly used to secure physically your PC display from spying eyes or prevent you from  someone to install a spying software or leak private data from PC HDD to an USB drive.
People who are coming from the wonderful MS Windows OS   are certainly used to quick shortcut key combination to lock PC screen with:
 

Windows key + L

 

So how to do Lock Screen on Linux?

On Linux locking your Screen the Quick Shortcut is:
 

CTRL + ALT + L.


Locking the screen is done (depending on the Linux distribution) by using by either using historically famous XScreenSaver if non-gnome / KDE graphical environemnt is used or if in Linux Gnome GUI with  gnome-screensaver and on KDE desktop manager with kscreenlocker.

 

Exact command executed on CTRL + ALT + L keypress on GNOME is:
 

gnome-screensaver-command -l


On KDE to manually lock screen command is:

kscreenlocker

Nomatter whether with GNOME or KDE its worthy mention that xscreensaver is more Screensaver rich than kscreenlocker and gnome-screensaver as it includes about 200 different Screensavers making screen nice to watch when you come back from a lunch.

For people with Windows key keyboard who are too used to using Windows XP / 7 lockreen WIN + L key shortcut to make Windows (key) + L keys combination work on Linux with GNOME desktop:
 

System -> Preferences -> Keyboard Shortcuts

Make Win + L keys combination work on Linux with KDE desktop
 

  1.  "System Settings" (KDE menu).
  2. Choose "Keyboard & mouse" (on "General" tab).
  3. Choose "Global Keyboard Shortcuts" on the left.
  4. Choose "Run Command Interface" from "KDE component" dropdown list.
  5. Choose "Lock session".
  6. Select "Custom".
  7. Click on "None" (button changes to "Input…").
  8. Compose your desired sequence by pressing appropriate buttons on your keyboard.
  9. Click "Apply".

 


For other desktop environments like Window Maker you can use xmodmap command to bind Win + L keys

Turn your Windows PC / notebook to Wireless Router with My Wifi Router 3.0 and TP-Link TL-WN722N

Wednesday, January 7th, 2015

my-wifi-router-3.0-turn-regular-windows-notebook-to-wifi-router

I've been to home of my wife's parents and for this Christmas, they have received second hand Acer Aspire notebook as a Christmas gift. So far they were using internet using their Windows XP PC which is getting internet here in Belarus via UTP network cable using ByFly ZTE ADSL router modem. As ADSL modem lacked wifh WI-FI Antenna (support) and there was already the Acer notebook which had to access the internet preferrably via Wireless connection, the option was to get a WI-FI router and connect it to the ADSL modem but as this would cost (20 EUR at minimum) and there was alreay Wireless (Receiver) adapter TP-LINK TL-WN722N unused, I decided to try make the TP-LINK Receiver and Windows XP PC to act as a small Home Made Wireless  (software) router.

Until I succeeded I've tried multiple softwares which all failed to turn the Windows PC to Wi-Fi Hotspot.
Here is list of few of the softwares I tried that didn't worked for some reason:

1. Wifi HotSpot Creator

WiFi-HotSpot-Creator-screenshot

Turn your PC into a Wi-Fi Router for Free!

Instantly share your internet connection with your friends and peers over Wi-Fi. Turns your PC into a Wi-Fi Router! And its Free! Wifi HotSpot Creator is said to be able to convert any Mac OS X and Windows PC to hotspot here is Wifi HotSpot Creator download website
Wifi HotSpot Creator is said to work with Windows Vista / XP / 7 / 8, however as I said it doesn't work for me on Windows XP.
 

2. Virtual Wifi router

Here is

With Virtual WiFi Router you can create a WiFi hotspot for WiFi Reverse Tethering on Windows 7 and for wifi supported mobiles and other wifi enabled computer to create a network and to share internet. Virtual Wifi Router in a minute converts your PC into a WiFi hot spot for free.

To make the program working it depends on .NET 4.5. Though the program looked like a superb it unfortunately was crashing on Windows XP. Below are few screenshots from program working on Windows 7.

3. My Wifi Router 3.0

Finally I've come across My Wifi Router 3.0 which is just another program that makes necessery Windows configuration to TP-Link TL-WN722N Wireless receiver Adapter to turn it into a homemade Wi-Fi router.

By default Amiss_papp Wifi is configured, this can be changed, however in my case when I tried changing it there were some issues, so finally I've had to re-install My Wifi Router to make it working again.
Once configured My Wifi Router there is the green button (Activate / Deactivate Free Wifi) as seen from screenshot.

As you can see My Wifi Router also allows to Share Videos over WiFi. Once I've tested the program and confirmed it as working, I had to configure it to automatically start on Windows PC boot.

This is done from Settings (located on backward triangle button, next to minimize function).
I had to set check in to  Auto Start and Software Conflict Detection.

Once connected to the TP-Link TL-WN722N (USB) Wi-Fi (High Gain) Receiver adapter in Windows Tray a new indicator will popup that a device has been connected. I've tested My Wifi Router and it seem to be working fine with 3 remote connected Wi-Fi devices (1 Notebook and 2 Nokia Lumia mobile phones). The speed of internet was fast and if I didn't know the connection is done in a software way via such an improvised Windows XP Wi-Fi network router I would think it is just a regular Wi-Fi network router.

One more thing I had to do to make the internet working I had to share the the LAN Network (ethernet card) Interface's internet from
 

Control Panel -> Networking -> Local Area Connection (Properties) -> Advanced

https://www.pc-freak.net/images/windows-xp-internet-connection-sharing-how-to-networking-screenshot-make-network-address-translation-windows-xp.jpg

A downside of My Wifi Router is I couldn't find a way to save password while connection to the newly created WiFi router with it, so each time I had to login I had to manually type in the password (default my wifi router password is 123567890). Re-typing password on each login is annoying but if you have to do it once per day in the morning when you turn on your notebook it is not such a big deal.

Once connected to My Wifi Router in Connection Management in Friends (tab) you will see a list with connected devices.

my-wifi-router-on-windows-xp-with-htc-and-ipad-iphone-connected
As visible from above screenshot default IPs which will be assigned to new connected clients to My Wifi Router will be in local network IP range 192.168.23.2 – 192.168.23.254.

Now all left is to Enjoy  your new Software Wi-Fi router 🙂

Sick again – Hoping God to solve it all – and no desire to study

Thursday, September 27th, 2007

Yesterday I was out for a coffee with Tony an old frined from the Old metal days, after that I went outwith Lily I drinked 200 gr of Vodka and a Beer. I was pretty desparate actually and I got very drunk I got home 04:10 and got to bed at 4:30. What can I say life is hard. Today Mitko called at dinner time and we drinked a coffee on the fountain. The night we went out in the Central park and drinked a beer per man. I’m starting to think about the meaningless of my life again, since my life seems without a real purpose and seems not going nowhere ( we humans are so weak ). Yesterday I have almost taken the decision to suicide. It almost a miracle after I send lily to her home and was going back home with the idea of my mind to suicide. Lily called and said she can’t unlock the door and everyone inside is sleeping and she didn’t want to disturb them. So we spend more than an hour outside. Today I feel terrible physically again. I really can’t take it anymore I need Jesus to bless me with a healing (Save me Holy Lord, Lord Jesus son of the Blessed God have mercy over me the sinner heal me Lord and Deliver me from all sickness and affliction and pain Heal my Soul, Body and Spirit, make me whole to be able to serve you again :[ Amen) My computer went down twice today I have a problem with the cooling. The cooler should be cleaned but I guess this will happen after our Room’s repair is completed. By the way Both Pc-Freak and Jericho are on the terrace. Because repair works are being done into the room. Day after day I ask my self the question when I will be healed again. I do smoke a lot of cigarettes for which I’m ashamed of myself (But it’s an act of desperation). By the way I don’t have any desire to study anymore I’d like to do things with FreeBSD and learn stuff. If God is merciful to me and heals me probably I’ll continue to live otherwise I guess I’ll end badly. Very often come to the point Nobody out there cares, them I feel the presence of God’s spirit I remember the Bible’s instruction towards doubtful mind and try return back to the Faith of the Eternal, It’s like a sort of schizofrenia (I believe, I don’t believe). I’m sure both cannot be true. Very often I think I deserve more but since God’s rightous probably that’s what I deserve. I tried do good for so many people and to care for as much people I’m very discouraged because as a reward I see it like receiving this infirmity and sickness … Something have to change or I’ll be gone …END—–

Raspberry Pi – Cheap portable credit-card sized single board Linux computer box

Thursday, November 7th, 2013

RaspberryPi tiny-computer running Linux and free software Logo

Not of a the latest thing out there but I believe a must know for every geek is existence of Raspberry Pi mini computer Linux board. It is a geek credit-card sized mini PC on extremely cheap price between 25$ and 35$ bucks (e.g. Raspberry Pi model A and Raspberry Pi Model B).

Raspberry Pi hardware you get for this ultra low price is as follows:

  • Broadcom BCM2835 system on chip
  • ARM Mobile processor model ARM1176JZF running at 700 Mhz (overlocking up to 1Ghz is possible – overclocked RP is called Turbo 🙂 )!
  • VideoCore IV GPU with 512 MBytes of ram
  • No Build hard disk or solid-state drive but instead designed to use SD-Card as a Storage
  • two video outputs
  • composite RCA and an HDMI port
  • 3.5mm audio output
  • 2 or 1SD/MMC/SDIO card slot (depending on device model A or model B)
  • Micro USB adapter power charger 500mA  (2.5 watts) – Model and 700mA (3.5 watts)

Raspberry PI mini computer hardware running Linux explained picture

The idea of whole device is to make cheap affordable device for pupils and people from third countries who can't afford to pay big money for a full-featured computer. Achievement is unique all you need to Raspberry Pi credit card sized device is external keyboard a mouse, SD-card and a monitor, this makes a 700Mhz featured almost fully functional computer for less than lets say 80$ whether used with a second hand monitor / mouse and kbd :). A fully functional computer or full functional thin client for as less as 80$ yes that's what RaspberryPi is!

It is recommendable that SD-Card storage on which it is installed is at least 4GB as this is part of its minimum requirement, however it is best if you can get an SD-Card of 32GBytes whether you plan to use its whole graphic functionalities.

Raspberry Pi Hardware is not too powerful to run a version of Windows as well as there is no free version of MS-Windows for ARM Processor, so basicly device is planned to run free software OSes GNU / Linux. 5 operating systems are working fine with the mini-board device as time of writting;
 

  • Raspbian – Debian "Wheezy" Linux port
  • Pidora – Fedora mixed version ported to run on Raspberry Pi
  • Risk OS port
  • Arch Linux port for ARM devices
  • Slackware Arm
    FreeBSD / NetBSD
  • QtonPi

Recommended and probably best distro port is for Debian Squeeze

To boot an OS into raspberry PI dowbnload respective image from raspberrypi.org

– Use application for copying and extracting image to SD-Card like Win32 Disk Imager – whether on Windows platform

Win32DiskImager burning raspberry PI mini Linux card board computer box image

– Or from Linux format SD-Card with gparted (N!B! format disk to be in FAT32 filesystem), extrat files and copy them to SD-CARD.

Once Raspberry Pi loads up it will drop you into Linux console, so further configuration will have to be done manually with invoking plenty of apt-get commands (which I will not talk about here as there are plenty of manuals already) – you will have to manually install your Desktop … Default shipped Web browser in Debian is Midori and due to lack of ported version of flash player for ARM streaming video websites like youtube.com / vimeo.com does not work in browser. There is a Google Chrome for Raspberry Pi port but just like with Midori heavy object loaded websites works very slow and thus not very suitable for multimedia.

Raspberry Pi device is very suitable for ThinClient use there is a special separate project – Raspberry ThinClient Project – using which a hobbyist can save 400$ for buying proprietary ThinClient.
