UltraVNC

Not sure if this is exactly a feature request...

Could we have a new project for configuration such as the config-lib in TightVNC?

It would make configuration a little more abstract and I think it would help with some precompiler conditions such as disableing the registry for remote support tools ...

Sorry for this late reply...

I usually do some work on uVNC on my summer hollidays and if I have a backup copy it must be on that computer... but not sure I kept a backup copy there :(

It shouldn't be hard to rewrite the whole thing again but on my office computer I have VS2010 and the new version ...

The way the server connects to the repeater is also quite simple, however the code behind it can have several degrees of difficulty. This is so because the RFB protocol is focused on a client-to-server connections and not the other way around; therefore you may find servers that won't allow reverse ...

The first step on the handshake (First step when communicating with the VNC server) would be the version. A server would send something like:

RFB 003.008

This states the server is using RFB protocol with version 3.8. The current repeater will reply with a non-existant version. The exact reply ...

LOL so you are the one to blame for my burning ears!

In those cases my brute-force concerns go away... however, since the modified repeater is focused on standard clients and this may not be an option. If I'm not mistaken the DSMPlugin will come alive before the authentication phase so I guess this ...

Hi zorzy,

It's been a long time since I wrote my last post.

The project of the modified repeater was basically a proof-of-concept on how you could hack a field such as the password field (present on all VNC clients) in order to send the repeater identifier to get any standard VNC client to get ...

Not really assuming it is a Linux firewall... Just took it as a cheap example. I recall Firewall-1 also had dynamic rules (never managed a Cisco ASA, but guess it shall be possible).

The setup, from the administrators point of view is a pain in the ass... Configuring the dynamic rules, a secure ...

Will you add repeater support at any stage?

I'm currently developing a VNC client based on VNSea just to gain repeater support on the iPhone/iPad without the use of the modified repeater (Thus allowing the password to be enabled through a repeater connection for some extra security). If any iPhone ...

The best I could think of, before running into expensive hardware tokens, is creating a VPN to an empty VLAN, then creating a firewall rule in order to access the VNC port of the machines running the VNC service from that VLAN. This way the VNC services get protected through a VPN while the VPN ...

Wouldn't it be better -for security concerns- to run a VPN, and connect though the tunnel with the computer? I used this method in an old job and it works fine (Much cheaper than the licenses you're talking about), however it is certainly more tedious than running GoToMyPC or LogmeIn, but it should ...

The Chat system could allow for extended chat features.

I've tested a modification making the chat system work in an IRCish fashion. As simple as the chat system gets right now it would send:

:<DISPLAY_NAME>!<USERNAME>@<COMPUTERNAME> PRIVMSG :<MESSAGE>

...or...

:<USERNAME>@<COMPUTERNAME ...

Hi B,

More than an idea it's just a trial . I found it would be easier to give a test run chaning the configuration settings than running into RESX (look-a-like) files to store the localized resources. However, I find the size increase way too high only to achieve this goal. Maybe the filesize can ...

Hi,

This is the origina UltraVNC 1.0.9.6 but libxml2 has been added to it. Although not all of the code has been replaced yet from INI file to XML, the dialogs have started to use the XML file. In order to speedup the MOD most of the functions used for INI settings have been cloned for XML settings ...

Latelly I had no time to code.... and now I've bumped into another thing I would like to get some feedback from you:

Since I'm probablly going into XML for language resources I though it could be nice having the settings in an XML file aswell. I've used libxml2 on my initial attempt. The code used ...

I'll publish a simple guide, maybe even a simple batch file or something to help out...

However, right now, the project is in an alpha stage (Although a kind of intermidiate release between alpha and Beta has been released). Some changes are taking place and will change the configuration settings ...

I think security shall work -although I haven't tested it out- since the DSM Plugin option is still there.

You need the ultravnc.ini in order for the application to get it's configuration. Keep in mind, if you're using the download URL for configuration settings the DSM setting shall be present ...

Maybe there is some misunderstanding about this modification... The repeater doesn't run on an web server. The repeater runs like the original UltraVNC 2011 repeater. The only difference is that it uses the standard HTTP protocol to update connection status to the repeater.

Basically you can mirror ...

Repeater version using libCurl (sources only and libCurl included):
http://www.megaupload.com/?d=M2XTPMU9

In addition:

libCurl also alows other protocols as SMTP that could send an email to the administrator when a remote server connects to the repeater... and many other protocols... Reason why ...

Sure :) It just relies on the standard HTTP protocol, so it would be independent of the platform the HTTP server is running on.

I have the repeater running on my Windows Laptop, and the PHP script is hosted on my ISP's server.

The only requirement is that the server allows some kind of scripting ...

I wish people would reply to this post:

I've compiled a new version of the Repeater this time using LibCurl instead of my own HTTP function. The resulting executable file size is 336.896 byte vs 144.384 bytes of the previous version. LibCurl has been statically linked.

I've removed some protocols ...

I've managed to develop a bit more the PHP script. The script is available at:
http://www.megaupload.com/?d=49O8KKVH

INSTALLATION

Extract the file contents (except README.txt and database.sql ) to your web server. Then edit both uvnc.php and repeater/index.php to set the $connectionString ...

I've talked about this idea on another thread. If someone knows how to develop on PHP and wants to make a nice user interface for it, it would be great as I'm still developping the Quick Support modification.

What is the "Mirror Service".

Basically the repeater will connect to a URL when the ...

I'm having a slight dilemma I wish to share with the people that are interested on this modification.

If I ran the repeater I usually do it in a router or a ReadyNAS. Therefore chances are that I shall take some time to fix the server auth on the repeater or port the new 2011 repeater to Linux.

I ...

Hi twagner,

Do you have the file ultravnc.ini in the application directory?

If so, can you post the section [repeater] you've created in a text editor?

The error you've specified is raised when it is unable to resolve the Host entry on the [repeater] section of ultravnc.ini .

Here is my testing ...

I'm developping a Quick Support application based on UltraVNC 1.0.9.5 with a Teamviewer look. Currently it is at a very early stage, but if someone wants to give it a try you can download the executable from: http://www.megaupload.com/?d=QZCR3O2Z

I still have to clean things up, change how the ...

Wouldn't it be easier to use the ISO639 codes? I think they are a bit more intuitive than Language IDs. Maybe instead of plain text files an XML would come in handy... With a simple parse it would be quite simple to update.

It could also be used for configuration files instead of the INI files ...

Hi,

It would be nice if the server automatically detected the user's locale settings.

I've changed the language resources files show it compiles to locale specific names, for example:


vnclang_es.dll
vnclang_en.dll
...

Next step... Where the resource DLL was being loaded I canhed the line ...

I haven't had a look at the new repeaters source code so I can only guess that the repeaters generates the HTML code on the fly and oesn't have a directory structure such as a standalone HTTP server... Neither have I had an in-deepth view of NoVNC sources... but I guess most of NoVNC's code could be ...

The repeater interaction I was proposing:

Since the repeater has a new web interface where you can see the servers connected to it we could show this lines as a link. If you click on the link NoVNC would come up starting -automatically- a connection to that server.

This way the remote server would ...

It would be great to include TightPNG Encryption to UltraVNC.

TightPNG Encryption can be found in Kanaka's fork of libvncserver located at https://github.com/kanaka/libvncserver

It is used with NoVNC ( http://kanaka.github.com/noVNC/ ) viewer developed by Kanaka. This VNC viewer is developed ...
