What is VNC2Go?

VNC2Go is a VNC client (viewer) that runs on MIDP-enabled devices. It lets you control any desktop server running a VNC service, from any mobile device that supports Java Midlets, such as mobile phones and PDAs.

Needless to say, a mobile phone is not the friendliest interface to remote control a desktop computer. However, when you need it, you need it. You can use VNC2Go to send yourself a document you forgot at home, restart a service that crashed, check for an expected mail message, look up a phone number you have at home, etc.

Hopefully, within a couple of years the mobile phone interface will be more mature for such advanced applications, with bigger and better resolution screens and simpler input mechanisms. VNC2Go has several input modes, to try and compensate for the not-so-friendly phone interfaces.

Pressing the star button cycles between the View, Pointer and Key modes and the menu options allow additional text and special key input:

A little indicator beside the input mode indicator is displayed when data is being transferred between the client and the server, to better understand what's going on at any given moment.

Supported VNC protocol version: RFB 3.3.

Supported VNC encodings:

Enjoy!

Installation and Configuration

To install VNC2Go, either download the JAR and JAD files (above) and install them from your computer onto your mobile device (via cable, bluetooth, etc. - check your mobile device manual for details), or browse directly to the JAD file above from the device's built in browser or Java Midlet manager.

VNC2Go will only work on MIDP (1.0 or later) enabled devices which support TCP sockets (the 'socket://' protocol). Unfortunately, some devices support only the HTTP protocol, in which case there is no way to access the VNC port. You can check your device's manual to see if it complies, or just try it out.

In the host setting, either a host name (such as "myvnchost.com") or an explicit IP address (such as 123.45.67.89) can be entered.

Some VNC references mention 'Desktop Numbers' or 'ports'. The mapping between the two is quite simple: the first desktop (desktop 0), which is the default, is at port 5900, the second desktop (desktop 1) is at port 5901, and so on. In other words, port = 5900 + desktop. If you are not sure, try ports 5900 or 5901, which are the most common.

If you have no idea what ports or desktop numbers are, but get nothing but errors while trying to connect, try these settings anyway, since they might solve your problem. For example, if your VNC server is running on the host named "myvnchost.com", try entering "myvnchost.com:5900" as the host name, and if that doesn't work try "myvnchost.com:5901", etc.

If you still get errors while trying to connect, make sure your server is accessible from some other VNC client software somewhere on the Internet outside your local network, such as from a PC at work or home (the one where your VNC server isn't located). If this doesn't work, then either your VNC server isn't setup correctly or your firewall is blocking the VNC port. Fix this problem first (check your VNC server or firewall documentation for help), and once it works, try VNC2Go again.

On some devices, data buffering optimizations cause the communications channel to get stuck, usually while the "Recv Version" status message is displayed. If this happens, disable the 'Optimized Buffering' configuration setting and try again. Otherwise, leave this setting enabled for better performance.

If you do manage to form a connection but authentication fails, make sure you've entered the password correctly - the password is case sensitive ("password" is not the same as "Password") and some devices may automatically capitalize the first letter as you type it in or make it all lowercase or all uppercase. Just make sure it comes out right.

Regarding password length: the standard VNC protocol supports passwords up to 8 characters in length. If your server allows you to select a longer password, this is likely a bug, which gives a false sense of security from choosing a long password - in practice, only the first 8 characters of the password you selected are actually being used. If this is indeed the case, just try connecting using only the first 8 characters of your password, and it should work. Of course, some VNC protocol extensions might actually use longer passwords or stronger authentication algorithms - those are not currently supported by the standard VNC implementation.

Screen size is also configurable, for devices with limited memory or slower connections - a smaller size means less runtime memory usage and less network traffic per screen update (but it's less comfortable to work with).
