Kindle Touch USB Networking/SSH

[ChrisKaos]

I'm afraid I only understood about six of those words..

But really, I don't understand most of what you're saying. I wouldn't say I'm a computer novice, but I am complete crap with the technical details and terms, as is probably obvious at this point.

If what you say is true, then you have a LOT of learning to catch up on before this forum will be useful to you.

Configuring a network is a trivial matter compared to most of what is discussed here.

At a very minimum, you need to learn the basic terminology that is the very foundation upon which this forum has grown, and which allows us to communicate technical ideas, so that you can understand the answers that we provide to your questions.

If you do not understand the basic terminology of networks and networking, then go learn it, or don't do it unless you have tools that automate and hide all the details for you. Those tools are not in these devices (such as a DHCP server).

I was being slightly hyperbolic. I know the basics of configuring a network and such things. I was speaking in general terms about not understanding. While I appreciate the help given, I did originally ask for a guide so I could follow along on my own without having to further bother people.

Now, my problem here is you've said that my computer's IP should correspond to the first three octets of the Kindle IP, i.e. 192.168.15.201 as you suggested. I can't use this, as my router's IP is 192.168.1.254 and it would not allow me to connect to the internet if I used the above IP, since the octets do not correspond to my routers.

Must I set a static IP each time I want to SSH into the device, and remove it when I want to connect to the internet? Surely a solution where I can be connected to my router and SSH into the device.

On the wiki, it says I can use Wifi to access the device, using the device IP I listed before. Wouldn't that be a more viable option?

There should be new network interface created when you plug your Kindle to the PC.
So when you go to network adapters you should see two of them. Then on the second one you edit your computer IP.

[hawhill]

You need to read the intructions carefully that you get. As soon as you plug in a Kindle in USB network mode, a new network interface should show up on your PC. You need to set the IP address of that, not of your LAN or Wifi interface.

Please accept that we don't like to do hand-holding through every single step. Use Google and forum search when you encounter things unknown to you. Not wanting to annoy you, but it's a bit frustrating to put other people through this when they are simply not ready.

You may set more than one IP address on a network interface, even under Windows.

Also note that the directions in this thread to "match the first three octets" is a "keep the directions simple" artifact, not a technical requirement.

Later, after you establish network communications between your kindle and a single machine, you will probably find you have to move your Kindle's IP address to the same sub-net your router is using if you want your Kindle to be able to access the internet.
But by that time you should know what needs to be changed, so don't worry about it now.

Note: The above "match the first three octets" to get Internet access through your router from the Kindle is to meet a likely restriction in your router's firmware.
Most consumer router's firmwares only do 8-bit routing tables.

Unless, of course, your router is also running Linux, a likely possibility.
But those directions would be really tossing you into the deep end of the pool, so stick with the directions given in this thread for now.

knc1: we're talking about USB networking here. It's IP networking over a P2P interface. Of course it might be configurable on the Kindle, but it defaults to a certain IP address on the USB network interface and it _will_ have a netmask and route set. And it's very probably a /24 subnet (where /31 or for conservatives, /30 would have been sufficient). So for now, "match the first three octets" _is_ a technical requirement. The Kindle would not interface with addresses outside its network. You would need to set explicitly a new netmask or at least proper routes on the Kindle to overcome this.

That part where you write over moving the Kindle's IP address does not really make sense to me or is somewhat incomplete. Putting the Kindle in the right subnet isn't enough. It would also need a proper default route. Doesn't really make sense to me for USB networking, since you would also need to bridge your LAN to the USB network interface on the host PC. I don't see the point here, routing on the host PC would be sufficient.

Ah, but I was writing of the non-Kindle end of the connection.
Which was where the apperant conflict in the quoted passage occured.

Of course it is incomplete.
The O.P. is already drowning in the shallow end of the pool.
Why toss more water in his face?

Since we are doing some off-topic nit-picking here anyway...

A /31 assignment is not "for conservatives" it is a dedicated point-to-point (P2P) link.

A /30 subnet is the smallest possible IPv4 subnet (with two special purpose addresses plus an address for each end).

The __default__ of USBnetworking on the Kindle is probably a /24 although I haven't personally confirmed that.

A 192.168.0.0/16 subnet on the non-Kindle end of the connection would allow traffic over both the 192.168.15.0/24 and the 192.168.1.0/24 subnets.
You do not have to match a /24 with only a /24, you can use any subnet of which the /24 is a proper subset (and hence my statement about "match the first three octets).

The Linux USBnet "gadget" driver provides a complete Ethernet interface device, connection media just happens to be a USB cable in its special case.

[hawhill]

Oh, yes, that's more proper terminology... And of course you're right about the host PC perspective. What is important for the OP is basically: More than one network interface means more than one device to configure addressing for :-)

In the diagnostics menu you are allowed to change the third octet, but the fourth octet is still 244, and the host PC is still expected to be at 201, or things like nfs (and other stuff) will fail.

In earlier kindles, the usbnetwork hack lets you assign any IP address, as I did in my "mntusb" script (which uses 10.10.x.2, where each of my older kindles uses a different "x", so they can all be connected and and accessible at the same time).

Here are more details that may be helpful to ChrisKaos (and others): https://www.mobileread.com/forums/sho....php?p=1906267

Believe me, I appreciate how frustrating hand holding can be, and again, I appreciate the help. But if you'll look at my original post, I didn't ask to have my hand held, I simply asked whether there was a beginner's guide, and if there was if someone could direct me there. As it turns out there is not. I probably would have left the issue alone if someone had just told me "No, what you're looking for doesn't exist." That did not happen, and someone (as well as yourself) did offer me some help, and I took it.

Further, no where in all of my search on here, the wiki or google has it said that using USB networking creates a new network interface on my computer which is what I need to configure in this situation. I'm sorry if maybe that seems elementary or obvious to you, but there's no way someone inexperienced would have any reason to assume that would be what would happen.

If there isn't enough help in this topic topic for me to go on, then I'll just leave the matter alone as I don't wish to further frustrate you or anyone else. Thank you again, I'll report back here if I'm successful.

The problem with search engines is they only search for your choice of keywords, not the meaning behind them. Try searching for usb0, and again for RNDIS. And search for Posts, not for Threads.

[hawhill]

ChrisKaos: Sorry, I didn't want to annoy you. I was a bit harsh, I'm trying to be more careful in my wording. I rather like to encourage for searching more insight. But I probably am too used to do that recherche work so that I lost a bit focus on that it isn't all that obvious to other people what seems obvious to me - no wonder, having spent a lot of time on computer business in general. There's nothing wrong with being a "user", every "developer" has been there.

[ChrisKaos]

I did say I would come back and let anyone who had posted here know whether or not I had been successful and I was. I had forgotten about this thread, however, and was reminded of it in another.

Thank you for those who helped, and I apologize to those whom I may have annoyed with my novice inquiries.
