Remote desktop (VRDE) only works on 127.0.0.2 ...

Post by Ra0 »

Hello,
I am trying to get remote access to my VM (Linux guest), but no success at all till now, unless I use RDP client locally on VBox host (Linux as well) pointing at

Code: Select all

127.0.0.2:<port_number>
It fails when I try to RDP from another machine or even from VBox host by giving VBox host IP@ directly or its hostname.

I have made sure that:
  • No firewall is running on my VBox host
  • VBox is listening on port_number I did set
  • Port is not already used by another process
  • VRDE is enabled
What I have tried (abstracts of VBoxManage showvminfo in examples below) :
  • many different port numbers ; e.g.

    Code: Select all

    VRDE property               : TCP/Ports  = "5000,5010-5012"
  • force VRDE IP@ (default was 127.0.0.2) to IP@ of VBox host ; e.g.

    Code: Select all

    VRDE property               : TCP/Address = "192.168.1.2"
  • Change authentication type (but since Null was working on 127.0.0.2, I expect the problem is not there)
Now I am totally puzzled. No idea what I could look at.
FYI, this is the "sum up" from showvminfo:

Code: Select all

VRDE:                        enabled (Address 192.168.1.2, Ports 5000,5010-5012, MultiConn: off, ReuseSingleConn: off, Authentication type: null)
Any idea ?

Please provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.

Well, I had a look to logs. Too many of them so I decided to clear them and start a fresh session.
Guess what ? Now it works ! :oops:

I am on this for many days and all of a sudden it works, without any change in my settings.
I don't have the root cause, but at least it works.
Sorry for the noise, here :roll:
