Access DSLstats Tp Link VR2800v
« on: December 28, 2017, 11:19:38 AM »

does anyone know how to access dslstats with this model? note that I have already tried this guide http://forum.kitz.co.uk/index.php/topic,14377.msg357441.html#msg357441 without success because probably the xdsl broadcom chip of vr2800v is different than VR 600/900/2800

I can't find out much about this model. Assuming that it does use Broadcom DSL chip, then the essential requirement is to obtain telnet access to the Busybox shell. I'm afraid I can't help with that, but if you find a way, then DSLstats should work with it.

Which model setting was used to make the config file? The VR900 model setting is the one most likely to work.

i tried all models, also VR900 model settings, but my webgui don t accept the encrypted config file, says "file not valid". Because the xdsl chipset of vr2800v (BCM63136V+BCM6303) is different than chipset of VR900/2600/2800. You should realize a new version of statposter with a model setting for vr2800v

I can try, but I will need a sample config.bin file saved by the 2800v, and I do not have much free time to do the work for the next 2 weeks at least. It may not be possible to make it work if TP-Link have changed their firmware significantly, it won't be anything to do with the different Broadcom chips.

Here the file conf.bin of vr2800v https://drive.google.com/file/d/1oJKAoAFhQNfgf3Pa6caEmuYUgdR1fi-1/view?usp=sharing
Please, please see if you can for tonight or tomorrow to release me at least one test version, I'll give you a donation as you like. I need to lower the snr via telnet and only by unlocking the shell can I do it

I've had a quick look, and the bad news is I think it will not be possible for me to fix it, because the problem is that the file ends up too big.

You could try deleting things from the unencrypted file that you don't need, to make the file smaller. I think the trouble with doing that is if you delete too much, then the router won't work properly.

I tried to delete things from the unencrypted file that I don't need and the file now is small, but the gui now don't accept the new file because says that is not valid  :(

UPDATE: The problem is that the file bin is too large because in the final .bin generated by statposter there are spaces between the strings that don't there are in the original .bin
See the images ejs



You must update Statposter with a new model for vr2800v

I expect working files created for other models look like that in RouterPassView.

StatPOSTer adds 2 bytes of zeroes after each 16 bytes of input, it does not do anything about ends of lines of text. I don't think that's the problem. The file ends up larger because it is not actually compressed, I do not know what compression routine is used, me attempting to reverse engineer the compression method would take a very long time.

I expect the tone of this did not translate well, but finding ways to inject commands into numerous TP-Link models that I don't even own has a very low priority in terms of things I need to do. Much easier to buy a different device from another company that does what you want. I only bought a 8970v1 because it was cheap and in theory capable of running OpenWRT, I don't actually use it, and I doubt I'll ever get around to putting OpenWRT on it either. I would not buy another TP-Link router.

And if I try to charge a bin of 2600/2800 (modified by statposter) on the webgui of the my 2800v? It can be compatible? Anyone that has 2600/2800 (that are a model of router similar to 2800v except for voip) can post here a bin? I want try....

Here there is a method of compression that work on tplink :)

That's where I got the encryption key and method from back in 2015. On the 8970v1, the config.bin file is only encrypted, and not compressed. On later models, including the 9980, the config file is both encrypted and compressed (made smaller, like in a zip file, but it's not an actual zip file).

I think someone else reported that they succeeded by putting the `telnet -p 1023 -l login` bit into the wireless network name, simply using the web interface as usual. I think I tried all sorts of things like that with my 8970v1 and nothing worked, but it may work on other models with different wireless components.
