Problem with v1.1.1.0 & SecureVNCPlugin on Win8

[ExpertSystem]

Long story short:
I have been using version 1.0.9.6.2 together with the SecureVNCPlugin.dsm (with and without keys) on Windows 8 RP x86 and Windows 8 Professional x64 without any problem.
Recently, I tried upgrading to v1.1.1.0 on my Windows 8 Pro x64, but:

• Without the SecureVNCPlugin/SecureVNCPlugin64 everything works fine.
• With the SecureVNCPlugin64.dsm, it aks for my password, but then I get an "authentication rejected" message

For what it's worth, I tried installing both v1.1.1.0 x86 and x64 and I tried using both SecureVNCPlugin[64] versions 2.3.0.0 and 2.4.0.0, but to no avail.
Any ideas ?

Thx in advance for your help,
ES

Found a possible cause
Workaround

You need to run once
uvnc_settings.exe
set plugin and press configuraion

This add the config settings for the plugin
DSMPluginConfig=SecureVNC;0;0x00104001;
And restart winvnc.exe ( if it was already runnning)

Thx for the reply.

Unfortunately it didn't work:
As you suggested, I ran 'uvnc_settings.exe', chose the SecureVNCPlugin64 on the 'Security' tab and pressed "Configuration".
But the options where all grayed-out, so I couldn't "configure" anything.

Still, I don't think this should be the root of my problem, since I have a configured the plugin from the 'Admin Properties' dialog and I have noticed that -in my 'ultravnc.ini' file- there is already an entry regarding the plugin:
"DSMPluginConfig=SecureVNC;0;0x00104001;<hash_of_my_pass_I_guess>"

EDIT:
By further investigating the issue, it turns out that:

• If I configure the plugin with a password with <= 8 characters (or no password at all), it works fine.
• If I configure the plugin with a password with > 8 characters, then I get the "authentication rejected" message.

[Rudi De Vos]

Pressing the configure was only needed to set
DSMPluginConfig=SecureVNC;0;0x00104001;
in ultravnc.ini
Server crached if plugin was used and DSMPluginConfig="", forgot to check for empty string in code.


hash_of_my_pass_I_guess: this is the passphrase
If this is set, you need to use the passphraze instaed of the vnc passwd

Thanks for the hint...

Another issue..
if passphrase is used, you should be able to enter more then 8 chars, seems also something
is wrong with the passwd/passphrase detection

Pressing the configure was only needed to set
DSMPluginConfig=SecureVNC;0;0x00104001;

I see ! Still, like I said, this line was already in my 'ultravnc.ini'

hash_of_my_pass_I_guess: this is the passphrase
If this is set, you need to use the passphraze instaed of the vnc passwd

That's what I meant . I am using the passphrase, of course.

if passphrase is used, you should be able to enter more then 8 chars, seems also something
is wrong with the passwd/passphrase detection

Exactly !
Just to make sure I was clear enough:
If I don't set a passphrase, I do get authenticated using the password (which is perfectly right).
If I set a passphrase (either <= 8 or > 8 characters long) I can't get authenticated with the password (which is perfectly right).
If the passphrase has <= 8 characters, I do get authenticated (using that short passphrase) (which is prefectly right again).
If the passphrase has > 8 characters, I can't get authenticated (which seems like needing fixing).

Looking forward to your reply !
Thx again for your time !

[Rudi De Vos]

files updated ( number is still 1.1.0, didn't update the version for this 2 fixes.)

fixed server crash when
DSMPluginConfig=

fixed
phassprase >8

you can download the zip and replace the viewer/server exe
Both need to be replaced.

server need to be replaced for the DSMPluginConfig="" crash
viewer need to be replaced for the phassprase >8

[ExpertSystem]

Thx for the fixes !
It works like a charm now

I have additionally a problem:
the /password switch does nothing when SecureVNCPlugin is used, it always asks for the Password. Without DSM Plugin OK, in old Version 1.09 OK.

[Chris]

/password Switch Problem still exist in 1.1.2

p.s. we are using VNC with Repeater

[Rudi De Vos]

next on the aganda... first fixing keyboard issue's

[Rudi De Vos]

please test 1.1.3

[Chris]

thx Rudi well done, /password now ok!
