Using integrated Dameware Connection with VNC does not connect due to password error

Hi there,


since we updated to Dameware 12.5 from Dameware 9 our existing Dameware host entries configured with VNC Server do not connect. The error Message is:
"This VNC server requires VNC authentication. Please enter the VNC credentials in the Remote Connect dialog."
When entering the credentials in Dameware Remote Connect window it works fine.


Any help is greatly appreciated!


Regards


Michael

Hello Michael,

We'll take a look at this, thank you for letting us know.

Hello,

We use command line parameters to send the Information in RDM.

Here's a list that we found for DameWare;


Could you please try through command line out of RDM to see if it works?

Also, are there any special characters in your password?

Hi Support,

good suggestion, thank you!

It does work when i use this:
DWRCC.exe -c: -h: -m:t-13364.myskm01.myskm.net -vnc: -a:0 -p:mypassword

But it does not work when i use this RDPM configuration:

It doesn’t matter which Authentication mode is choosen. We do not have Special characters in our Passwords.

Hello Michael,

I think I know what's causing the issue. Does your Dameware entry link to a credential entry that has a username? I think since RDM finds a username in the credential entry, it automatically passes it in the command line. Could you confirm?

Hello Hubert,
no, my credential entry only contains a password.

Hello Michael,

I attached to this post a small application that simply returns back the command line parameters you sent it. Could you rename the executable to "dwrcc.exe" (what RDM looks for) and change the path to point to it in File > Options > Path > Configure Installation Paths. It should give you what exactly RDM is passing in parameters when you try to open your dameware entry.

That's it, great tool :-)
This works:
DWRCC.exe -c: -h: -m:t-13667.mydomain.net -vnc: -p:mypwd
DWRCC.exe -vnc: -c: -h: -m:t-13667.mydomain.net -p:mypwd
DWRCC.exe -vnc: -p:mypwd -c: -h: -m:t-13667.mydomain.net


This does not work:
DWRCC.exe -c: -h: -m:t-13667.mydomain.net -p:mypwd -vnc:
DWRCC.exe -p:mypwd -vnc: -c: -h: -m:t-13667.mydomain.net


The output of your tool was:
-c:
-h:
-m:T-13667.gemeinschaftsklinikum.net
-p:pwadmin
-vnc:


So I think, in newer versions of Dameware the -vnc: parameter must be set before the -pwd: Parameter
Is there a way to change the order of parameters in RDPM?

Good find, Michael :) We'll change the order and put "-vnc:" (and also "-r:", which is for RDP) as the first parameter. This will be available in the next build of RDM. If you could let us know if this works it would be appreciated.

I checked the function in version 13.6.2 and it works fine now!
Thank you!
