Using the same key on multiple servers / multiple clients

[OwenPigott]

I have just finished spending quite some time getting the MSRC4 encryption plugin working with UltraVNC Server/Viewer. I experienced pretty much all the errors people have posted on this forum and in the end got it working by generating the key first on the server, rather than the viewer as the plugin website tells you to.

I then distribute the keyfile and the plugin file from the server to any clients I want to connect to that server.

I click connect, enter the password, and then it logs me in and shows the encryption as being present in the title bar.

If I delete the keyfile it stops working - so I know it's functioning as it should.

What I would like to do is use this same keyfile on all servers and all viewers, since there is no solution for use of multiple keys in the viewer.

Is it even possible to do this? According to the plugin quick-start guide on their website, you generate the key in the viewer, but this fails.

yes take your key file and place it in the place in the unvc folder. If you are using the stand alone viewer make sure that the *.dsm file and the key file are in the same folder as the viewer

It won't work if I copy the key / plugin from one server to another though.

Here's my scenario:

We have multiple servers. Server A, Server B, Server C. And multiple clients. Client A, Client B, Client C.

Example situations:

If I generate the key on Client A then distribute the key and plugin to Server A, B or C - It does not work.

If I generate the key on Server A then distribute the key and plugin to Client A, B or C - It does work.

If I generate the key on Server A then distribute the key and plugin to Server B, C, Client A, B, C - Client A, B and C can talk to Server A but not Server B or C.

If I generate the key on Server B then distrubite the key and plugin to Server A, C, Client A, B, C - Client A, B and C can talk to Server B but not Server A or C.

I would like Clients A, B and C to be able to talk to Servers A, B and C by using the same plugin and key files placed in all server / client unvc folders. Currently this does not work.

Seems to be working now actually. Only tested on two servers with the same key, but working nonetheless.

It would be good to know why this sporadic problem occured though if anyone has any ideas.

Hi,

Would you please describe how you got it to work. I am having the same issue and not been able to fix.

Thanx
