no connection between VISTA/win7 and XP

Post by m.sco »

Hi! sorry for poor english
Glad of using UltraVNC on my XPs, but a few days ago i've tried it on win7 (reverse connection) and got an APPCRASH "winvnc.exe", faulty module "ntdll.dll" at win7 side.
I'm using it in user mode via .bat file with string

Code: Select all

 ...start UltraVNC\winvnc.exe -connect Ñ…Ñ…Ñ….Ñ…Ñ…Ñ….Ñ…Ñ…Ñ….Ñ…Ñ…Ñ…::yyyy
Tried it on Vista and got the same error. :cry: There is an interesting moment - when i close the APPCRASH window, the listening viewer on the other side shows message "Conection failed - Error reading protocol version"

Do you have any idea?

don't forget -run and you need winvnc 1.0.8.2 or above if exist.

old
start UltraVNC\winvnc.exe -connect Ñ…Ñ…Ñ….Ñ…Ñ…Ñ….Ñ…Ñ…Ñ….Ñ…Ñ…Ñ…::yyyy

new
start UltraVNC\winvnc.exe -connect Ñ…Ñ…Ñ….Ñ…Ñ…Ñ….Ñ…Ñ…Ñ….Ñ…Ñ…Ñ…::yyyy -run

redge, thank you for a quick answer
I've read the Server's command-line help already and know about the -run switch. I tried it and didn't find any differences in behaviour with my old .bats (from old VNCs)

My VNC server crashes not while starting, but while connecting. And it doesn't matter incoming or outgoing connection I try to establish. I also try to do it manually via menu and get the same crash. (I was not correct enough, when described the problem for the first time).

I've just tried VNCviewer on Vista - and also got appcrash ->
So, both the server and the viewer crashes on my Vista when trying to establish a connection. The faulty module is ntdll.dll for both programs


ps: using version 1.0.8.2

disable all entry from startup anything is not necessary at both side.
try vncviewer connect to winvnc
and retry until you find where is the bug,

we know nothing about your config or software.
is there anything software optimization for network

trying to find solution in the dark is a loose of time.

have spent a lot of time, disabling and enabling different services and so on
But that was not the correct way - finally I tried to disable AESV2Plugin.dsm. And the problem disappeared.

I didn't try it first of all, because i have had a folder with UltraVNC with my set of batch files - and it worked perfect for the time.

So I got an APPCRASH ntdll.dll error on:
-win7 6.1.7600
-winVista 6.0.6000
-winVista SP2 6.0.6002 (rather fresh with all updates up today)
runing the server, while the viewer was on XP

hm... That plugin's name was my favourite :|

ok, just replace at both side aesv2plugin.dsm by the new securevncplugin.dsm but require both side uvnc 1.0.8.x (vncviewer + winvnc.exe)


aesv2plugin never worked... on vista/7 except as application mode as xp sp3 compatibility

thank you, redge!
i tried to run in xp-compatibility mode, but also got a crash, may be my actions were not correct enough

I see, that you have been testing securevncplugin.dsm for a while. Could you please tell me, how should I use it without passwords via WAN? I have to generate both server-side public key, and viewer-side private key? Will it work? if I use several servers and viewers, can i use them with the same keys? sorry for offtopic
