UltraVNC

The x11vnc -ncache is a hack for client-side caching that will work with unmodified VNC Viewers, provided the viewer can be made to "hide" the cache region from the user's view. Sometimes this happens automatically (SSVNC on unix or macosx), sometimes the user needs to manually resize the viewer ...

krunge, thank you for your clarification so is this way ... OpenGL --> TurboVNC --> x11vnc ---> ssvnc --> turboVNC --> OpenGL , correct ? No, that's not what is going on. On macosx x11vnc now happens to use OpenGL's interface 'glReadPixels' to read pixels from the screen into its copy in RAM. This ...

I want to try OpenGL to OpenGL via ssvnc direct to x11vnc :-) The MacOSX native server can now use OpenGL for the screen capture. In nearly all cases this is faster than the raw framebuffer capture method. Redge, this isn't what you think it is. It is not sending OpenGL commands to the viewer side ...

An update, in the ssvnc 1.0.29 development version: http://ssvnc.sourceforge.net/dev/ssvnc_no_windows-1.0.29.tar.gz I have added some support for ultravnc sectype 17 for RFB 3.8. SecureVNCPlugin is not working yet, but MSRC4 (1.2.2) seems to be working OK. Via MSRC4 (or cleartext) MSLogon should ...

There appears to be lots of protocol incompatibilities in Ultravnc 1.0.9.*

It looks like they will be a lot of work to sort out and to provide connections to earlier Ultravnc servers. I also don't have much time nowadays. So I am going to wait until later to make SSVNC work with Ultravnc 1.0.9.

Mac support is pretty Alpha at this point in time, if you code up something nice or at least figure out the syntax it would be awesome if you'd share the knowledge. I hope to have a native Mac viewer someday but I wouldn't plan on it anytime this year. Hi supercoe, Are you asking me this question ...

It should be "ID:777777" not "777777" Also for the VNC viewer it should be port 5900 not 5500. The following is from the ssvnc proxy documentation: MODE II REPEATER: For the mode II repeater both the VNC viewer and VNC server initiate TCP connections to the repeater proxy. In this case they pass a ...

This problem (discussed in more detail with gcornilescu via email) is fixed in the ssvnc 1.0.26 development bundles here:

[topic=16787][/topic] maybe I don't understand her request ? Oh yes, now I understand better. Yes, the SSVNC viewer has automatic SSH tunnel creation for a VNC connection. SSVNC can do this on both Windows and Unix/Macosx (plink.exe on Windows, ssh elsewhere.) It can also (via easter-egg) just ...

That's what I want, an admin on another subforum told me it was possible with this software...

Could you send a link to the thread? I'm still not clear what you want, and if you really need ssvnc (this thread.)

I'm not sure what you want to do. It sounds like you want a shell login (interactive terminal) on Windows instead of the full Windows desktop???

okey, I got it to work with msrc4. Good, glad it is working for you now. but "no VNC authentication needed" means no password needed or? Yes, viewer is telling you no VNC password was asked for. Is this right log? Yes, it looks very good. Now I´m somekind of confused. Why didn´t work msrc4_sc ? W ...

Anyways: on my sc.exe - the msrc4plugin.dsm is version 1.2.2.0 you can check it, when you go to properties (at least in Windows) and "Version" tab, but I cannot check the one in ssvnc as it integrated to the program as you should know. Anyway, as you can see our logs are pretty much different ...

copy/paste in xterm is pretty bad with mid mouse click etc, you know any better way to do it? 1. Click and release Left mouse button at the desired start position. 2. Scoll down (either Middle mouse button drag on scrollbar or use Shift+PgDown) 3. Click and release Right mouse button at the desired ...

what version of MSRC4Plugin are you using. It´s highly unlikely that the fault is there Can you please give me links for: SSVNC MSRC4Plugin SSVNC: I've used these, but I am pretty sure earlier ones work too: http://downloads.sourceforge.net/ssvnc/ssvnc_no_windows-1.0.24.tar.gz?use_mirror= http:/ ...

Here is a complete example. ultravnc_sc.exe was built about a year ago with this 'helpdesk.txt' entry: [HOST] Internet support B -plugin -connect 192.168.100.15:5500 -noregistry -plugin -connect 192.168.100.15:5500 -noregistry and the rc4.key in the same directory. Sorry but it has been a long time ...

Well, but the sad story here is that it gives me exacly same thing as when I run ./ultravnc_dsm_helper & ./tightvncviewer It works fine for me. I am using a sc exe I built a year ago. Are you using some sort of newer/latest version of UltraVNC SC app and/or builder? Would the changes be ...

ultravnc_dsm_helper rev:msrc4_sc /path/to/rc4.key 5500 localhost:5530 and & aka exacly same line as I tried before, but it continues... open: Permission denied ??? I'm pretty sure this means the ultravnc_dsm_helper process could not read the /path/to/rc4.key file. I think you will need to open up ...

it@it-laptop:~/Desktop/ssvnc/Unix$ ./ssvnc exec: 3: wish: not found You need to add the 'tk' package. E.g. 'apt-get install tk' or if that doesn't work 'apt-get install tk8.4'. Then try it from the ssvnc gui: 'Options -> Reverse VNC Connections' and 'Options -> Advanced -> UltraVNC DSM Encryption ...

Try running with: ./ultra_vnc_helper rev:msrc4_sc ./rc4.key 5500 localhost:5501 i.e. add the "rev:" tag. Does it work for you via the SSVNC gui? If, so then you can use 'ps' to find the commands running and their cmdline arguments. That's how I was reminded "rev:" is needed for reverse connections ...

Hello Vic and Redge, Yes, Vic and I have discussed this at length. I think the only thing I want to point out is that although full 64 bits Anonymous DH is better than 31 bits, real security applications consider 512 bits the absolute minimum, and most use 1024 bits or more for the exchange ...

Do any of the Linux VNC viewers support MS Login authentication? if any would, then I am thinking the one by the maker of x11vnc would be the most likely too. Yes, about a month or so ago I added UltraVNC MS-Logon support to the dev version (1.0.23) of SSVNC (Unix and MacosX viewers only): http ...

See redge's post #2 above.

since i am using uvnc SC with xtightvncviewer on linux is there away to do this for xtightvncviewer? In the SSVNC current development/testing version (1.0.21) there is now viewer-side scaling for linux/unix. It is experimental, and so I suggest using x11cursor because it is less prone to crashes in ...

Here is the successful test example I used for connecting with SSVNC via the UltraVNC repeater.exe proxy repeater and using the MSRC4 DSM plugin. VNC Host:Display: :0 VNC Password: *** Proxy/Gateway: repeater://192.168.0.2:5900+10.0.2.53:5902 The above Proxy/Gateway is equivalent to using the easier ...

so in my ssvnc I have the following setup VNC host:display = vnc://:0 VNC password = xxxxxx proxy/gateway = repeater://my.repeater.ip:port+my_uvnc.server.ip:port I am not sure what led you to use "vnc://:0" when the ssvnc documentation on using the uvnc repeater suggests to use ":0". The "vnc ...

thank you for the explanation, there the hole, use silently the vnc password instead the key or key not enough encrypted let another key used instead check the requirement is not enough for start encrypted connection. ie key don't have enough data . Yes, that does sound like undesirable app ...

AFAIK and to my understanding the "key" is just broadcasted in the begining of a transaction thought ANY key you make will be consider as "the key" and both client and server will encrypt data with this key (Any key you make) correct me if wrong thought The keyfile data (i.e the stuff in arc4.key ...

No I just experienced without know the reason why this so easy making a fake key or manual create ke and your explanation is mathematical and i'm not very aware of mathematical (i'm poor in Mathematical exams) Sorry for not being clear. The key is just 128 random bits (= 16 random bytes) made when ...

open notepad write text as example: "aesv2.key" (without quote) save document as aesv2.key copy the file for both vncviewer and winvnc try to connect with uvnc 1.0.4RC16 + aesv2plugin.dsm both side between xp to xp. succes remark: the aesv2.key is not encrypted, this just a clear text "aesv2.key ...
