x11vnc and DSM plugins

Postby supercoe » 2012-03-14 14:14

I haven't received a response from Karl Runge on this so I was hoping someone here could help me out.

Hi Karl,

I don't know if you remember me but I'm the creator of ChunkVNC and I
have a question for you about how I get the SecureVNC plugin working
with an UltraVNC server and your vnc viewer.

Everything seems to work just fine when I use the older MSRC4 plugin
other than these messages:
ultravnc_dsm_helper: encrypt - WARNING: MSRC4 mode and IGNORING random salt
ultravnc_dsm_helper: encrypt - WARNING: and initialization vector!!
ultravnc_dsm_helper: decrypt - WARNING: MSRC4 mode and IGNORING random salt
ultravnc_dsm_helper: decrypt - WARNING: and initialization vector!!

Not a big deal as my main goal is to get the software to function with
SecureVNC anyways, I just wanted to see if I could get it to work at
all!


So here is my setup I'm having trouble with:

SERVER:
XP Home with a default UltraVNC server 1.0.9.1 configured with the
SecureVNC plugin passphrase of "password1" and an IP of 192.168.1.123
I tested this setup with the UltraVNC viewer + SecureVNC plugin and it
works as intended.

VIEWER:
Hackintosh Lion 1.7.2 using bins from the
ssvnc_no_windows-1.0.29.tar.gz release and an IP of 192.168.1.105



1) Start the helper.

./ultravnc_dsm_helper securevnc pw=password1 5901 192.168.1.123:5900

Then it outputs:

ultravnc_dsm_helper: waiting for connection on port: 5901



2) Start the viewer.

./vncviewer localhost:5901 -ultradsm

Then the helper outputs:

ultravnc_dsm_helper: got connection: 5



Sadly unlike my test with the MSRC4 plugin it doesn't seem to do
anything but hang here for about a minute.

After the timeout the helper outputs:

securevnc_setup: fail read rsabuf: n=0 len=12


The UltraVNC server will say:

"Failed to connect to 192.168.1.105!"



I've also tried generating the .pkey and using
"./20120208_Viewer_ClientAuth.pkey" instead of "pw=password1" but get
the same result.


I know you're a busy guy and I apologize for asking you to do tech
support for me but I've exhausted all other means of trying to figure
this out.
If you could point me in the right direction or tell me if my syntax
is wrong I would greatly appreciate it!


Thanks, Nick

Any news on this?

I'm trying to use ssvnc with uVNC server with SecureVNCPlugin64.dsm enabled and I'm seeing the same thing.

It connects, then hangs until timeout.

The ssvnc side says:

Code: Select all
ultravnc_dsm_helper: got connection: 0
securevnc_setup: fail read rsabuf: n=0 len=12
vncviewer.x11: VNC server closed connection

2017/04/09 15:42:28 VNC Viewer exiting.

vncviewer command failed: 0


And the uVNC debug log says

Code: Select all
Sun Apr 09 10:44:57 2017
vncmenu.cpp : ############### Usernames change: old="Richard Cooke", new="Richard Cooke"
--The system cannot find the file specified.

This is uVNC server 1.2.1.1 on Windows 7 64-bit PRO.

ssvnc version 1.0.30 on MAC OS/X 10.11.6 El Capitan
