noVNC ready: native WebSockets, canvas rendering

[vkyk]

I am newbie in using vm. Try ubuntu 14.04.3 server i386 in vm. Have set up vmubuntu.vdi and mounted iso at phpvirtualbox page but unable to use novnc. I use https in N4F and firefox.

Setup of vmubuntu:
14.04.03 32bits
32G vdi
4G ram
adapter: bridged adapter (also try NAT)
remote display: enable at port 5910


In phpvirtualbox page, I run vmubuntu and am able to see the ubuntu installation page in Preview box. Then go to novnc page, if Host: 192.168.1.100 (example), Port: 5910 and input password, quickly replied "noVNC ready: native WebSockets, canvas rendering" and then immediately become "Server disconnected (code: 1006). If I put Host: https://192.168.1.100, it show "noVNC ready: native WebSockets, canvas rendering". I also try it in IE11 and same results.

What mistake I have made?

Did you use NAS4Free IP address? Host is not GuestVM's address.
If noVNC does not work, you can use normal VNC client such as UltlaVNC.

Dear daoyama-san

I go to noVNC webpage from phpvirtual page ie use the N4F IP, not guest IP. I install ultra vnc (VBoxVNC) which works.

Thanks.

If you have installed VirtualBox extension, you need uninstall it before using builtin version.
The builtin version is not compatible with extension version.

Dear daoyama-san,

I do not install any VirtualBox extension before.

I am still unable to complete the installation of Ubuntu server 14-4 LTS. It always hangs in different stages. I'll try again.

Why do you use 32bit version Ubuntu?
64bit Ubuntu on 64bit NAS4Free is enough.

Install Ubuntu 64 (VGA 640x400 only?) -> Intall GuestAdditions (800x600 and more)

Note: some confirmation is hard to select on 640x400.

Dear daoyama-san,

Now I have installed 64bit ubuntu server but fail to install webmin.

Would you mind to advise how to install GuestAdditions.

Thanks for your help.

daoyama-san,

[noVNC ready: native WebSockets, canvas rendering] is caused when Protocol at HTTPS in System | General Setup is selected. I have tried in 2 N4F:

NAS4Free 10.2.0.2 (revision 2067) x64-embedded; 122310 XSDT1951 AMD Athlon(tm) II X4 640 Processor 8192MiB RAM

another is 2067 for 86-embedded in old HP server

If I use HTTP, these x64 and 86 embedded N4F can use noVNC which show "Connected (unencrypted) to: VBoxVNC.

Is it possible to fix in further version?

[noVNC ready: native WebSockets, canvas rendering] is caused when Protocol at HTTPS in System | General Setup is selected. I have tried in 2 N4F:

That was:

1. certificate is not used by VirtualBox.
2. NAS4Free does not provide certificate/private key for vboxusers.

For workaound:
So I've added to insert certificate to libvncserver used by VirtualBox.
And WebGUI's key is copied to vbox-cert.pem as same as cert.pem for lighttpd.
(it should be fixed in VirtualBox side)

r2111 and later should work on both HTTP and HTTPS.
Thank you.

daoyama-san

Many thanks.

Edited:

I just updated to R2115 but unable to use noVNC in HTTPS mode. I have tried to 1) select HTTP first and then re-enable HTTPS, 2) disable and re-enable VB, 3) manually delete conf of VB after disable VB and then re-enable VB and 4) reboot N4F. All these methods fail. What procedures should I do in order to use noVNC under HTTPS?

Thx.

I fresh install NAS4Free 10.2.0.2 (revision 2118) x86-embedded in HP Intel(R) Xeon(R) CPU 3040 @ 1.86GHz 0MiB RAM and note that when using HTTPS, Chrome can view at "Connected (encrypted) to: VBoxVNC" but both IE and Firefox still cannot. I use win 7 pro and have cleared cache in Firefox (IE is first time to use).

Updated:

It is further proved that in my updated N4F R2118 64-embedded, Chrome can use NoVNC but firefox can't.

Hello,
sorry for bringing this old thread up, but I have exactly the same problem as described from the starter of this thread in his first post. Unfortunately the discussion above drifted a litle bit around and I cannot see if the initial problem was solved. Could also be that I'm just too unexperienced:-)

I already have tried different browser on different computer with different Windows versions. I also have tried with both, HTTP and HTTPS. All above without succes. I always get: server disconnected (code: 1006).

My aim is to play around with nas4free and have Ubuntu installed in a vm, just to learn. Is there another (easy) posiblity than noVNC?
Because I do not have any experience, neither with nas4free nor with virtualbox and noVnc, I don't know how to solve this issue.

If anyone could kick me to the right direction: welcome!

Thank you!

[lux]

pls try an "VNC Client" such as TightVNC, UltraVNC, RealVNC etc. - this works for me

greetings

[yupsmith]

Thank you lux for the reply!
As I am a newbi, I even do not know where to start.
I'm on the point bevor installing Ubuntu (clicking on the start button). Could you please give me a step by step guideline how to go on? I suppose I have to install one of the a.m. VNC clients before start to install Ubuntu but how can I install a VNC client in nas4free?

Thank you!

yspsmith,

Instead to install UltraVNC client in nas4free, I install it in my w7.

Firstly, you create a new VM in N4F and mount your IOS disk image (I use ubtunu). Actual the procedures are same as to normal run VM in w7 or other systems. Then run or start this new VM. On the other hand, I run UltraVNC client in my W7 and then input the same ip address, port and password in UltraVNC which will connect your new VM. UltraVNC become console and I can log in ubuntu VM.

I still find Chrome is the only browser can use NoVNC (but sometimes doesn't).
