1. Introduction

Remotix is powerful yet simple to use client for remote access. With the recent addition of NEAR protocol, you can connect to your computer from anywhere and with almost zero lag.

Remotix supports:

1. NEAR - Remotix own low-latency protocol
2. Remote Desktop Protocol (RDP)
3. Apple Screen Sharing
4. VNC

It allows you to connect to any remote computer running any operating system from your Android device.

2. Main Screen

2.1. Remotix Account

You can register in remotixcloud.com and use your Remotix account for multiple purposes - connect to machines using NEAR, have all your remote connections and credentials stored and synchronized across all devices.

When logged in, this pane is displaying your account information page and notifications from Remotix Hub.

2.2. Stored Computers

Remotix stored computers screen presents a list of stored connections available to connect.

On the first connect to the nearby computer, you need to choose is the authentication type. After disconnect this connection will be added to the Stored list. All settings that you've selected or changed on-the-fly would be stored. The star icon to the right of connection name indicates that you have this connection in Stored list.

Connections you never visited before would have default "blank" thumbnail and no stored settings.

To add a connection manually:

1. Go to the menu and press the [ + ] button
2. Remotix will ask you to set the new connection up. The Host/IP field is mandatory; all the other fields are optional. If you leave the Port field blank, Remotix will use the default port value (3389 for RDP, 5900 for VNC).
3. When you finish, the new connection will appear at stored list with a default thumbnail.

When you disconnect from a connection, Remotix will save its screen for you as a thumbnail to help you recognize it later. The thumbnail will be refreshed at the end of every session. You can disable thumbnail saving by setting "Store thumbnail" option to off.

2.3. Nearby

Remotix uses Bonjour, NetBIOS and LAN scanners for discovering available computers.

• Bonjour: nearby servers on the local subnet that announce themselves using Bonjour technology.


• NetBIOS: all NetBIOS servers available on WiFi.
  


• Local Network: IP addreess/port scan of all computers available on WiFi interface.
  

2.4. Quick Connect

You may quickly connect to remote machine running Remotix Agent using this pane.

2.5. Application Settings

• Remotix Account (iPhone only) - login with your Remotix account to get access to all of your machines and set up connection and credential sync.
• Synchronization - select whether you want your connections and credentials stored only locally on the current device or synchronized across all devices with the same Remotix account.
• Master Password - turn on if you want Remotix to ask your device passcode, Touch ID or Face ID every time you start the application.
• Curtain Mode on Mac Connections - turn on if you want the screen to be automatically locked when you connect to remote Mac either via NEAR or Screen Sharing.
• Auto Reconnect - enables or disables automatic connection setup after disconnection, for example when you answer the call on your iPhone or switch to the other app on iPad.

3. Viewer

When you connect to a computer Remotix shows you the Viewer screen showing remote desktop. Please note: If you have connected using "Ask for observe" option, you'll be in the Observe mode and won't be able to control the server.

3.1 Gestures

Remotix provides multitouch gestures for the following actions:

• pan:
  
  
  
• zoom:
  
  
  
• click:
  
  
  
• double click:
  
  
  
• right click:
  
  
  
• drag:
  
  
  
• scroll: move two fingers in vertical direction to scroll vertically
  or (Mac OS X servers only) in horizontal direction to scroll horizontally
  
  
  
• show the hiding Dock or taskbar: pan the screen in opposite direction
  
  
  

3.2 Toolbar

Remotix toolbar contains the most useful buttons to manage your connection and to control the server.

• Keyboards
  Remotix allows you to use two keyboards: standard Android keyboard and extended one. Extended keyboard provides you with keys that you usually cannot access through standard Android keyboard, such as F1-F10, Escape and cursor keys. Special buttons for actions like "Cut", "Copy" and "Paste" are also included.


• Right & middle click mode
  This button will imitate right mouse click or middle click instead of left one while it is selected. It won't be released until you do tap (e.g. panning gesture won't cause it to release).


• Touchpad mode
  Touchpad mode button (the hand) will switch the way you control Remotix viewer. In this mode, your finger movements would move the cursor over the screen and tapping on the screen would actually tap at the position of the cursor. You can continue to use gestures like two finger scroll to perform scrolling and two finger click to perform the right click.


• Modifiers
  Modifier keys (⌃, ⌥, ⌘ / Ctrl, Alt, Win) are put on the toolbar. Once you press a modifier button, it stays pressed until released.
  E.g.: to close a browser tab, first you press the modifier (⌘ or Ctrl), then 'T', then modifier again.
  Note: if width of your screen is insufficient, modifiers buttons can be hidden. In that case try another orientation of your device.


• Cursor keys
  If width of your screen in current device orientation is enough - the cursor keys (←, ↓, ↑, →) are also present on the toolbar.


• Settings menu
  Press settings menu button to get access to full screen mode, zoom pixel to pixel or to change connection settings on the fly.
  • Disconnect select disconnect to terminate connection to current server
  • Settings opens connection settings which can be changed on-the-fly. After closing new settings will be applied immediately.
  • Take Screenshot Takes the screenshot of the remote machine and allows you to share it.
  • Zoom 1:1 would zoom the current screen to pixel-to-pixel ratio.
  • Fullscreen Mode hides the toolbar. To get access to toolbar press "Back" button. Notice, that in different versions of Android Remotix will also try to hide as many Android UI panels as possible.
  • Lock remote screen (Apple Screen Sharing only) Blacks out the physical screen on the machine you're connected to, preventing the others to see your actions on it.
  • Show Connection Info Displays HUD with connection information like rate, bandwidth and time connected.

3.3 External Keyboard

Remotix fully supports the external keyboard, including all modifier keys, such as Shift, Command and Windows button.

In some verions of Android you may need to set exact input type in connection settings. Set "Keyboard type" to "Hardware" for external keyboard.

3.4. Tips and Tricks (ScreenSharing)

• Dual-screen setup: you can choose whether you want to work with only one display of your multimonitor setup, or with all of them together, by choosing needed display in connection preferences on-the-fly.


• Spaces navigation: to move between spaces on a Mac, use the Ctrl+Arrow keys shortcut (unless you have disabled it on your Mac)

4. File Transfer

You can use Remotix file transfer feature to move files from any of your computers to the mobile device and back. File transfer is part of NEAR protocol, so you need to install Remotix Agent on the computer you will be connecting to and enable file transfer in agent settings.

All files you copy to your device are available in "Files" application under "Remotix" folder. If you want to copy from your device to the remote computer, please make sure you put your documents into this folder first.

5. Remotix settings

5.1 Common settings

• Synchronize Clipboard
  If set, Remotix would perform automatic clipboard synchronization if server supports it. If you copy something into the pasteboard on Android device, Remotix sends it to the server. The opposite is also true - copying on server would automatically transfer clipboard contents to Android device. Supported types include text. If remote server does not support automatic clipboard synchronization (notable example is old version of Apple Screen Sharing server), you can use "Send clipboard" and "Get clipboard" actions, whose would appear in Settings menu to transfer pasteboard to and from server.


• Invert Scrolling
  If set, vertical scrolling gestures will be inverted.


• Don't Dim Display
  If set, Remotix would block display from dimming while connected.


• Fullscreen type
  Allows to setup elements of user interface, which will be hidden in fullscreen mode - only Remotix toolbar, only Android toolbar or both.


• Dim toolbar
  Allows to dim constantly presented Android system bar (with buttons like "back" or "home"). This option may be usefull on tablets with Android 3.0 or later. Remotix can dim Android system bar when remote connection is established or when fullscreen mode activated. Also you can choose never dim system bar.

5.2 NEAR Settings

Authentication Options

• Ask if needed
  You will be asked about the authentication if it's required.


• No authentication
  If Remotix Agent allows, you will connect to the computer without authentication.


• Access Code
  Authentication by the Access Code, as displayed in Remotix Agent main window on the target computer.


• System Logon
  Uses Windows or Mac OS X user credentials to authenticate. Note that you will only be able to login into logon session or the existing session of the specified user.

NEAR connection options

• Quality
  Select the quality depending on your current workflow.

  Smooth is the best for games or video playback. It uses hardware-accelerated H.264 to encode the remote desktop. Sharp gives you the best quality picture at the sacrifice of frames per second. Balanced (the default) is optimized for the general use.



• Server Scale
  Enables or disables scaling of the remote desktop picture to optimize network bandwidth.


• Redirect Sound
  Enables or disables the playback of remote machine sound on your device.


• Hide Local Cursor
  If the remote machine displays cursor as part of the remote screen you can disable the local cursor rendering.

5.3 VNC Settings

Options for Mac-based (Screen Sharing) servers

• Keyboard through clipboard paste
  Having this option on you don't need to switch the keyboard layout on your server. You can type any national characters from keyboard layouts installed on your device. The only drawback of this method is that system clipboard and clipboard synchronization between your device and computer won't be available.


• Quality Level
  To have the best experience over different network speed Remotix allows selection of the quality level. You can choose between black & white, grayscale, medium, adaptive and full quality. The least bandwidth hungry is black and white. Adaptive quality codec provided by Apple Screen Sharing™ minimizes buffering and guarantees a fast start. It also provides a fast performance on average and slow connections, although it is rather CPU hungry.


• Color Depth
  This option is only available if Adaptive codec is selected. Choose 16 bit to lower CPU requirements (older devices).


• Server Scaling
  You can further improve performance of Remotix on zoomed out view by setting up this option. On the connect stage Remotix sends a command to server to send back downscaled image. This will reduce required bandwidth and free your device resources.


• Display
  Apple Screen Sharing only. If Mac you're connecting to have multiple displays, Remotix allows selection of the active monitor. Option include "Combined" to use all displays, or each display individually.

Options for other VNC servers

• Operating system
  Selected server OS defines extended keyboard layout (OS-dependant modifiers) and Dock / taskbar icon for the corresponding gesture and ensures correct work of cut/copy/paste extended keyboard buttons.


• Preferred Encodings
  You may change the preferred order of graphical encodings used by Remotix for every server. Encodings that require increasing bandwidth decrease processing requirements, and vice versa. While connecting, Remotix will use the first encoding in list which is supported by server. If all encodings are turned off, the raw encoding will be used (which does not perform any compression and needs the widest bandwidth).


• Color Depth
  You can adjust color depth of the Viewer screen. The higher the value - the greater the width of bandwidth used. You can get satisfying level of picture quality vs. performance adjusting this option, e.g. on GPRS connection you need to set it on 8 bits.

5.4 RDP Settings

Authentication Options

• Domain
  Enter Windows domain here if your computer is part of domain. If not, leave empty.


• Username
  Enter Windows username here.


• Password
  Enter Windows password here.

RDP connection options

• Desktop Size
  Select the resolution of the remote session.

  Autofit mode adapts RDP resolution to match your iDevice. RDP resolution will be changed on rotations and entering/leaving fullscreen mode. Note: live resolution change only works for non-server Windows editions, starting from 8.1.

  There are "Fullscreen (Portrait)" and "Fullscreen (Landscape)" options for Remotix to automatically calculate the resolution, so it fits the screen completely in Portrait or Landscape orientations correspondingly. Also, you can set up custom sizes if you select "Custom".


• Desktop Scale
  Select the scale factor used for desktop elements. This is especially useful on high-resolution devices, like Surface Pro.

Performance options

• Performance
  Select the performance profile of the connection. In "Auto" mode, Remotix detects whether you are running on Wi-Fi or 3G and selects "3G" or "LAN" correspondingly. You can also select "Custom" profile and set up the details manually:
  • Wallpaper determines whether desktop background would be drawn
  • Full Window Drag if set, windows are moved with contents, otherwise only the outline will be displayed during drag
  • Menu Animations determines whether menus would appear immediately or animated
  • Theming if set, your Windows theme will be applied
  • Cursor Shadow sets the cursor shadow drawing
  • Cursor Settings disables cursor blinking
  • Font Smoothing determines whether font smoothing will be in use
  • Desktop Composition enables or disables desktop composition


• Compression
  Set to "On" if you want Remotix to compress all RDP traffic. Note: this can be actually slower due to increased CPU requirements on Android device.


• Color Depth
  Color depth determines the number of colors in the picture RDP would transfer. Higher value requires higher bandwidth.

RD Gateway

If your company is using Remote Desktop Gateway to provide an access to your machines within your company network, specify the gateway pameters here.

Audio Options

• Audio Playback
  Selects audio mode.
  • None no audio will be played or redirected
  • Play on Computer audio will be played on the remote machine
  • Dynamic Quality audio will be redirected to Android device and audio quality will be adapted automatically
  • Medium Quality audio will be redirected to Android device with medium quality
  • High Quality audio will be redirected to Android device with high quality


• Audio Recording
  Determines whether audio recoding (speaking to the microphone) will be transferred to remote machine.

Advanced Options

• Console Session
  Set to on if you want to connect to the existing first session on RDP server (Windows Server 2003 only).


• Startup Program
  Specify the path to the executable, which will be started on user logon (Windows Server only)


• Working Directory
  Specify the working directory for the startup program. Only applies if startup program is set. (Windows Server only)

6. SSH Tunneling

You may use a secured connection through SSH (SSH tunnel) to access your machine if you have SSH server available. To establish a secured connection, enable "Use SSH tunnel" option in Remotix connection preferences.
You will be asked to provide the following information:

• SSH username
  This is the username that you'll use to login via SSH. Usually it's the same as your OS login on the remote computer.
  To enable SSH connection on your Mac, do the following:
  1. Go to System Preferences -> Sharing pane
  2. Enable Remote Login service


• Authentication type
  You may choose either interactive or public key-based way to authenticate.
  For interactive, you have to enter password associated with the SSH username. For public-key based authentication, you need to have a pair of keys. For detailed instructions, see section 10.
  


• SSH password (or Private key passphrase)
  You may fill it in advance, or leave blank if you want to be asked for this password on every connection attempt.
  


• SSH host and SSH port determine the intermediary machine SSH connection goes through.

8.2 VNC

You own a Mac

The easiest way is to enable Screen Sharing on your Mac.
Do the following:

1. Go to Sharing pane in System Preferences.
2. Select Remote Management service in the list and enable it.
3. Look to the right and make sure that access is allowed for all users.
4. Click the Options… button and enable all options in list.
5. Click the Computer settings... button and enable "Anyone may request permission to control screen" option.

After you perform these steps, your Mac appears automatically under Bonjour section in Remotix.

You own a PC

First, you have to choose one VNC server. The most popular ones are Ultra VNC and Tight VNC.

• How to set up a Tight VNC server
  1. Go to Tight VNC website and download Self-installing package for Windows.
  2. Install it. Default installation settings are OK.
  3. Start TightVNC in Service mode if it didn't start automatically.
  4. You should see a TightVNC service icon in tray, informing you that VNC service started successfully.


• How to set up an Ultra VNC server
  
  1. Go to Ultra VNC download page and download the latest version of Full installer.
  2. Install it. On Select Additional Tasks step make sure that two upper checkboxes are checked ("Register UltraVNC Server as a system service" and "Start or restart UltraVNC service").
  3. After installing, go to server preferences and set your own VNC password.
  
  If you want to enable access by using your Windows username and password, do the following:
  1. Enable Require MS Logon and New MS Logon options,
  2. Click Configure MS Logon Groups button and enable full control for the user you will log in as.
  3. In Windows XP you have to disable Force Guest option in registry. Executing this .reg file will do the job: disableforceguest.reg.zip.
  
  Always make sure that UltraVNC is able to save changes in preferences. In Windows XP you need to uncheck "Protect my computer and data from unauthorized program activity" option; in Windows 7 you need to "allow this program to make changes to your computer".

After you perform these steps, perform rescan using local network or NetBIOS scanner to discover your machine.

9. Make your computer accessible outside the local network

We recommend using RemotixCloud, which makes your computer automatically accessible over internet without any additional router or port configuration. Visit remotixcloud.com/help for more information.

For manual setup, if you want to connect to your computer while not being in the same subnet, you need to do the following:

1. Ensure that your computer has a stable host name or IP address.
   If you don't have static IP or a host name, use a dynamic DNS service, like dyndns.org.


2. Configure port forwarding on the network router to pass incoming connections from router to your server.
   You need to forward connections to the port of your computer (3389 for RDP, 5900 for VNC). Please refer to your router documentation for detailed instructions on how to do this.


3. Configure firewall on your computer to accept incoming connections on the port.
   Mac OS X enables this automatically when you turn on Screen Sharing or Remote Management. On Windows, you'll need to add the RDP port to the exception list of the Windows Firewall.


4. As alternative, you can use SSH tunnelling to access your local machine through the other machine with SSH running. Refer to Section 6.

Back to top

10. SSH tunnel using authentication key instead of password

The advantage of this method, is that you don't need different passwords to log on different servers. Once the public key is installed on the server, access will be granted with no password question. You can also authenticate via the personal private key on all servers, needing not to remember several passwords.

If target server running Windows, you can use SSH tunneling to perform secure connection from your device to intermediary machine (SSH host). Refer to Section 6.

After you create two associated keys, the public key has to be stored on the remote computer host, and the private key should be stored on your device.

To generate a pair of keys on a Mac, do the following:

1. Open Terminal.app
2. Execute this command: ssh-keygen
3. Enter passphrase that will be the password needed to use your private key. (This could save you from unauthorized access under your username if the device with private key is stolen.)
4. Repeat passphrase
5. Open the folder where your pair of keys was saved. If you used default location, you may go there using this command: open ~/.ssh/

To install the public key on the server, simply add the contents of client's ~/.ssh/id_rsa.pub to the server's ~/.ssh/authorized_keys.
In most cases, this command will do the trick: cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

To generate a pair of keys in Windows, do the following:

1. Download PuTTY
2. Extract files
3. Launch PUTTYGEN.exe
4. Select SSH-2 RSA
5. Click "Generate"
6. Enter passphrase that will be the password needed to use your private key. (This could save you from unauthorized access under your username if the device with private key is stolen.)
7. Save public and private keys to any directory with names you like

To save your private key to the device:

1. Connect your Android device to your computer
2. If you are not able to open your device - try Android File Transfer or refer device manual.
3. Drag the private key file (usually named id_rsa) anywhere in internal device memory

To connect securely using this key:

1. Go to Security preferences of your connection in Remotix
2. Select Public Key authentication type
3. Select Private key file from the list of stored keys
4. Enter key passphrase if needed
5. Save connection preferences.
