PLEASE PLEASE PLEASE READ THE USAGE NOTES: HERE

you WILL NEED SSH ACCESS TO THE DEVICE (one time at least)
after that you should be cool.

[twobob]

This ones for you <AcidWeb> :P

[twobob]

I have slightly reworked this into a simple script.

reposting.

[twobob]

[root@kindle bin]# /mnt/us/extensions/sshfs/sshfs

me@192.168.1.1's password:
<I enter password>

[root@kindle bin]# ls /mnt/us/documents/extra/

A. Bertram Chandler
Adams_ Douglas
Brian Stableford
Christie Golden
Christie_ Agatha
blah....

umount /mnt/us/documents/extra/
to tidy up...

[twobob]

there are a couple of issues surrounding this.

a) ssh - you need it on the kindle. to this end a client is provided:
/mnt/us/extensions/sshfs/bin/ssh


b) YOU MUST RUN THIS (ssh) SEPARATELY AT LEAST ONCE before you run the script. WHY?

/mnt/us/extensions/sshfs/bin/ssh me@192.168.1.1

Host '192.168.1.1' is not in the trusted hosts file.
(fingerprint md5 99:e9:da:d2:9f:6e:28:78:c4:c7:8b:26:da:da:a9:91)
Do you want to continue connecting? (y/n) y

if you DON'T do this... you will get:

read: Connection reset by peer

Don't say I didn't warn you...


after this you can run the script

/mnt/us/extensions/sshfs/sshfs

with impunity.

[twobob]

Maybe Niluje knows a way to tidy all this rubbish up.

Right, that came up the last time sshfs on the Kindle's side came up: it needs an ssh client in $PATH, one that's actually called ssh. USBNet only install the dropbear client as dbclient, IIRC. No idea if it would handle dropbear's client, or if it actually requires OpenSSH...

Either way, I have an OpenSSH build on hand, since I build the server, so that's not terribly annoying.

One other thing: since part of FUSE actually lives in the kernel, I'm not quite sure bundling a newer fuse userland library and/or one built against a different Kernel is completely safe. If it blows up, that's probably why ;p. Not that familiar with the FUSE API/ABI, so the point may be moot.

Probably can't get around the fingerprinting, that's SSH after all . It'll probably need an SSH client that stores/expects a known_hosts file in a directory that doesn't go poof after a reboot, though.

[twobob]

I did mess around with "expect" for a while to pass the "Y" back into the question... but meh I hate expect... and yes this time was just as little fun as last time.

So I ditched that idea. Add the fingerprinting, get over it.
Do that everytime if you don't change away from /var/tmp/root...

Perhaps this will honour the $HOME env_var, never thought of that.

also built sshpass for the exceptionally lazy - may bundle one day... undecided.

Bottom line is: if you expect to neatly connect to the ssh on your PC? expect to do a tiny bit of work... Thanks for giving it the eye-over.

At least you didn't LOL at my efforts Thanks dude.


EDIT: perhaps I could wrap this in a KTERM???
Then at least the average user would be able to see the login interface without too much "effort"

hmmm....

[NiLuJe]

Yeah, OpenSSH does looks at ~ for the .ssh directory, but I don't remember if it honors HOME, or check the passwd file.

IIRC, my build looks for the global one in /mnt/us/usbnet/etc, so I'll try with that.

This is a pretty specific piece of software for a pretty specific usage, I don't think it needs more hand-holding than this . If it works as it should when used properly, done! .

[twobob]

fair enough.

You know me. Like to hold hands...

It's nice piece of kit though!

coupled with KOreader this really kicks some A

[NiLuJe]

'kay, seems to work fine with my OpenSSH build, it calls ssh itself without need to do it beforehand, and the known_hosts file behaves...

AFAICT, it needs the OpenSSH client, it's using settings the dropbear client doesn't handle.

I'll probably merge it into USBNet .

[twobob]

YAY!!!!

I did something useful!

*pats self on back*

Thanks mate


EDIT: Wait! does that mean I am gonna get a credit in the USBNET notes?
I may explode with joy :P

[dsmid]

The known_hosts check can be surpassed by adding this to ssh_config:

Host *
        StrictHostKeyChecking no
        UserKnownHostsFile /dev/null
        LogLevel ERROR

[dsmid]

OpenSSH client for Kindle sounds very interesting.
OpenSSH client + proxytunnel + web proxy = SSH over 3G from Kindle Keyboard 3G.

[hawhill]

Driving SSH(fs) via expect is a bit awful of an idea, SSH has it's private/public key authentification for doing such stuff seamlessly :-)
