After th connections breaks done, iam back to the terminal and after leaving it it freezes on homescreen .... argh i have to do the 30sec reboot after this.. sucks ^^



2 things have to be done by me:


1) integrate kvncviewer into launchpad or KUAL....
2) fix the connection problem... but hawhill did it .. so its possible...
hawhill, if you have time to type a few lines , it would be very cool. (Iam going to drive to Göttingen with a Kasten Bier , when we did it :P)

good night

I just had an idea:

Would it be better to use WiFi instead of USB? - for example on battery scuffing?
Would that lead to a harder configuration concerning this tunneling?
Hmm

It's a bit complicated with the naming. The Kindle is the SSH host (or "server"), the PC is the SSH client.

However, for VNC, it's the other way around in our scenario. So the PC is the "VNC server", the Kindle is the Client.

When you use VNC over the USB networking link directly, parts of the Kindle software will kill the connection under some circumstances in regular intervals. I don't know if it's different via Wifi, but I doubt it - actually I think that this "feature" had only Wifi (and WAN for relevant devices) connections in mind and applies to the USB connection due to not being explicitly disabled there.

The connection dropping does not affect SSH connections. This opens a loophole: SSH has a "forwarding" feature. It can create tunnels for TCP connections (which is the protocol that VNC uses). The important thing is: It can open these tunnels for both directions (independent of the "direction" of the SSH connection). (NB: In fact, all connections mentioned are bi-directional. They just differ in which side initiates them.)

I will need a bit of time to properly describe how it fits together in layman terms. But actually there are description of the general workings on the web. Just google for "ssh forward vnc connection". It's a typical use case for VNC because VNC has no strong authentification/encryption, so when VNC is used over the web, SSH tunneling to the VNC server is often used. In our case, we would just create the tunnel in the different direction (or open the SSH connection in the different direction, depending on how you see it).

Actually, opening the SSH tunnel could also be used to start the VNC client on the Kindle - and both things could then be triggered by the host PC in one go.

But a fair warning: It's a bit complicated and I won't find enough time soon to write it all down. Maybe it gives the right ideas for others to come up with more practical advise or scripts.

thx!

in the ubuntu docs i found something maybe relevant:

"

Remote Port Forwarding

Remote port forwarding lets you connect from the remote SSH server to another server. To use remote port forwarding, you need to know your destination server, and two port numbers. You should already know your destination server, and for basic uses of port forwarding, you can usually use the port numbers in Wikipedia's list of TCP and UDP port numbers.

For example, say you wanted to let a friend access your remote desktop, using the command-line SSH client. You would use port number 5900 (the first VNC port), and destination server localhost:

ssh -R 5900:localhost:5900 guest@joes-pc

The -R option specifies remote port forwarding. For the duration of the SSH session, Joe would be able to access your desktop by connecting a VNC client to port 5900 on his computer (if you had set up a shared desktop).

"

applied to our task it would be "-R5901:localhost:5901" I think. The -R Option is the key. got it...

But what to do with "guest@joes-pc" hmmm.. and how to change the vncviewer configuration... they write "on his server"... hmm

so check how it is described in the config file that causes that message to be generated.
also check the config file line endings.

i googled something else

"
1st Way:

Do the thing with the router that giga said. (What you really wanna do is reserve a ip for the mac address of the NIC on your server. You can figure out it's NIC by typing 'ifconfig'. Its the number in the form of xx:xx:xx:xx:xx:xx next to HWAddr. Most routers allow this, and it sounds like you have this set up).

Next, go to your ~/.ssh folder, and use your text editor to change/create a file named config (full path should be ~/.ssh/config ). Make/add an entry in this form:

host MusicBox
Hostname <ip address>
User <your username>

After that, create an ssh tunnel to your musicbox,by using this command:

ssh - N -L 5900:localhost:5900 MusicBox

and then in a seperate terminal:

vncviewer localhost:0"


maybe i can apply this... i dint changed that file ...

Not necessarily.
Just delete the offending line in ~/.ssh/known_hosts (or delete the file altogether)

maybe its easier to start from scratch with the above method and new keys
Is hat a good idea? @ knc1. Can I use your walkthrough with openssh?

hmm i generated new keys but..

"
debug1: Roaming not allowed by server
debug1: SSH2_MSG_SERVICE_REQUEST sent
debug2: service_accept: ssh-userauth
debug1: SSH2_MSG_SERVICE_ACCEPT received
debug2: key: fonzie@fonzie-desktop (0xb7fd68d0)
debug2: key: /home/fonzie/.ssh/id_rsa ((nil))
debug2: key: /home/fonzie/.ssh/id_dsa ((nil))
debug2: key: /home/fonzie/.ssh/id_ecdsa ((nil))
debug1: Authentications that can continue: publickey,password,keyboard-interactive
"

and iam in the loop of asking for publickey
it took time again after
debug2: key: /home/fonzie/.ssh/id_ecdsa ((nil))


i switched back to dropbear and the same problem as before.. taking its time after
key: /home/fonzie/.ssh/id_ecdsa ((nil))

until printing

debug1: Remote protocol version 2.0, remote software version dropbear_2012.55
debug1: no match: dropbear_2012.55

at least the same spot as before.. good point to go to bed


P. S. Grüße zurück
