Vnc And Passworded Directories

[1101]

ok, i have two ideas. If it allready exists or isn't possible for a specific reason, please elaborate.

anyway; i am wondering if you could hook up a gp2x to a pc and use the gp2x to view a vnc server - through the usb port. Of course you would either need the computer to have a small resolution or have the gp2x scroll around. I figure its all open-source so the vnc application should be viable, but would it be possible to get the data down a usb?

also it'd be cool to have a password protect on gp2x folders, hell even the whole unit. I dont know if this allready exists, but it would be useful - any ideas on getting that to work?

thanks for reading this far.

The fbvnc pre-compiled arm binary will run and try to connect, but then it crashes before displaying anything (or was it an error? can't remember now). Can't imagine it would take much to get it to work but I haven't had any time to look at the code.

The pre-compiled binary only contains the client (i.e. only useful if you want to view your PC's screen from the GP2X, which may be interesting to try with a wireless connection, but it is slow on the Pocket PC so I assume it would be on the GP2X too).

The client was all he was asking for which is why I mentioned fbvnc. Thats also the reason why I haven't played with fbvnc much - I came across it while looking for a possible way to get the gp2x display onto a pc via usb, so it's a server I'm more interested in myself rather than a client.

Yes, i did only want the client. It would be good for controlling headless computers that serve a limited purpose - like mp3 playing(car), or ftp/http/irc/etc. I dont think it would be slow if you didnt have a keyboard, ran in low resolutions and in low colour depths. wireless would be cool, but atm i think even wired could be quite practical.

Passwords on folders is unenforcable, but password-protecting the entire unit (via a startup script) is feasible. It would only prevent casual misuse though, because a thief can always reflash the device of course.

so i have been playing around with the networking options from firmware 2.0, and i cant get it to work. I directly blame XP for being useless crud, it continually produces an "unrecognised device" error and wont let me assign drivers. I really hate this OS - it sucks.

anyway, so i figure i only really need the gp2x to interface as a monitor essencially. So if i could get the USB networking going, it would only require me to stream a video of the current video output to it. How plausable is this?, i figure realtime refresh of a screen this small should be able to work through a usb.

Also the password thing would be as you said, just for casual misuse etc. So a startup script would probably do it, unless you used folder encryption or something.

yay double post.

So i found the usb problem; xp wouldnt recognise what the gp2x was unless you plugged it into the usb ports at the rear of my computer, funny joke.

So playing around with qtopia i see that theres a vnc function in it, so far i havent go it working, but its only a matter of time.

cool.

This is probably a bit involved; basically if you want to use VNC you'll either have to do IP over USB (and then put VNC over that, which is possible) or try to recode the VNC server and client(s) to work over USB directly (which is probably significantly harder).

Luckily, VNC is open source software (I'm pretty sure that most implementations are GPL) so you could definitely start taking apart the code and figuring out how to get it working on an ARM9 with whatever networking method you eventually decide upon. I believe Qtopia already has a VNC client (as you stated) so you're more or less set for that end of the bargain provided you can get it networking over USB.

I've seen some embedded machines that do this sort of thing over USB; the Gumstix springs to mind. I'm sure it's not that hard, it would just take a lot more involved hacking than I'm willing to put forward at this time.

I cant see a problem with running a VNC over a usb-network, as the network protocols allready exist (as does the connection). Also should a port of a vnc client be attempted it would simplify things a lot.

I have been unsuccessful in getting qtopia's VNC to function, its networked because opera can pull up webpages - so i dont know...

I am trying to get it to connect to a realvnc server, do you think this could be the problem?
