Folder Sync and ssh keys

[bjornar]

Hi! I'm quite new to android phones, but I must say that after some iphone years I'm fascinated by a phone that can be handled the linux way. But obviously I need some help: I've managed to set up Folder Sync at home, using a Samba share. It just works. But I would also like to add sftp support. I've created a keypar using ConnectBot. The keypar works at that application, but fails in Folder Sync. Error repeated on two different Android devices. So i guess the error is mine. I've included the log, and I hope someone has a clue for me! :-)

Info on supported keys can be found here:

However I am not sure the issue is with the key in your case.

[León Castillejos Fernández]

I'm having the same problem. I would suggest to focus on why that message is happening (" Error in login async task: Can't read key due to internal IO problems").

Exactly same diagnostic, same issue. Keys created with Connectbot work in programs such as ftpcafe with no issues, but your app throws a very fuzzy error such as "Can't read key due to internal IO problems".

I paid for this app just for the only feature which was SFTP syncing support with SSH keys, as no other app has this functionality, but I'm not getting what I paid for :(

I also sent you a log file just in case you need it, but it's approximately the same as this one has posted here...

Is this a bug in your app? Because other apps seem to be able to use perfectly all the Connectbot created key pairs, yours doesn't work. Am I missing something? Please fix this ASAP, thank you :)

Hi,

I got here after also getting this error.  For me the "internal IO problems" boiled down to a wrong pass phrase for the key.  Works fine with the right one now.  Maybe that's the problem in your case, too?
@TacitDynamics: maybe the error message could use some tuneup :)

"Can't read key due to internal IO problems:"

[León Castillejos Fernández]

My key has no passphrase and still fails.

[Maik Rungberg]

I have no pass for the key

Perhaps someone could generate a dummy key, that recreates this problem, and send it to me.

Hi Anders, firstly I love this application, and appreciate the work your company does. Unfortunately I am not at a machine where I can generate keys, but perhaps I could ask one question that may help narrow down the issue(which I am also having). Does Foldersync, recognize specific types of PKCS like PKCS #8 or #1 ? I just remember for a rival software, I had to convert the RSA key generated by connect bot into a PKCS 8 format, in order for it to work(at least from my experience)

[Support User]

FolderSync uses an external library for SFTP access. How it handles the key files I don't know. It is this one:  http://www.enterprisedt.com/products/edtftpjssl/overview.html

Thank you very much for your help Anders. After fiddling around a bit more unsuccessfully, I decided to just make a new key pair using the Cygwin console, set up a new password, appended my authorized_keys file to include the new public key, and put the new private key on my phone/client device, and everything is working well now.

Hi,

Did anyone find a solution for syncing directories via ssh keys. I am trying to login to linux server via my tablet and using ssh keys. I generated a pair via "ssh-keygen -t dsa". If I leave the password blank it works fine. However when I choose password, I start getting IO errors. Please help. This is no doubt an incredible app

thanks,

[Support User]

Are you talking about key or login password - there is a difference, and there are different fields to enter them into.

[Muhammad Butt]

THank you for replying my question. I am talking about ssh key. I have configured ssh server on a FreeBSD server and using foldersync to sync stuff to/from my android. 

You know when you create a keypair you have option to add password as an additional security. So if I add the password it stop working. However if i leave it blank it works fine.

The security issue is that if someone get hold of my private key they can log into ssh server.

let me know if you need more information

thanks again.

Muhammad
