RFB 3.8 Issues

[jerick70]

Hi,

A little background first. I am running Ubuntu 10.10 Linux with SSVNC 1.0.27 to connect to my Windows systems. I am using the MSRC4 encryption plugin with MS Logon Groups. I can connect fine with 1.0.8.2 server and this version of SSVNC. When I install 1.0.9.1 or 1.0.9.5 of UltraVNC server I cannot connect with SSVNC. Here is the output from SSVNC...

Proto: RFB 003.008

Connected to RFB server, using protocol version 3.8
Server did not offer supported security type:
sectype[0] 17
sectype[1] 113
Security-Type: 0 (rfbSecTypeInvalid) Latency: 3.61 ms

VNC Viewer exiting.

Any help would be appreciated.

Thanks,
Jeff

So no one can help with this?

I don't know if this will help. Here is the output from logging of the UVNC server.

is it work without plugin or with another plugin like securevnc ?
did ask user krunge owner and developer of ssvnc ?

There appears to be lots of protocol incompatibilities in Ultravnc 1.0.9.*

It looks like they will be a lot of work to sort out and to provide connections to earlier Ultravnc servers. I also don't have much time nowadays. So I am going to wait until later to make SSVNC work with Ultravnc 1.0.9.

1.0.9 follow the rfb 3.8 protocol.

1) Or your viewer tell it is pre 3.8 ( 3.3 3.7)
3.4 3.6 where no official protocols
Then viewer connect but without all ultravnc addons

2) The viewer need to support 3.8 without security type 17
Then viewer connect but without all ultravnc addons

3) The viewer need to support 3.8 with security type 17

rfb 3.8 defined types...

6 RA2ne

17 Ultra <<<<<<<<<<<<<<<<<<<<<<<<<<<<
18 TLS

An update, in the ssvnc 1.0.29 development version:

http://ssvnc.sourceforge.net/dev/ssvnc_ ... .29.tar.gz

I have added some support for ultravnc sectype 17 for RFB 3.8.

SecureVNCPlugin is not working yet, but MSRC4 (1.2.2) seems to be working OK.

Via MSRC4 (or cleartext) MSLogon should work, I can't test it completely because I can't remember how to enable it... If you try it out on Linux with the above tarball and report back to me I would appreciate it.

BTW, even without sectype 17 the ultravnc pseudo encodings: scale 1/n, chat, and filetransfer appear to be working, but need to test some more.

jerick70 did you test the version 1.0.29 from previous post of krunge ?
