It is.. It has to do with something coming with the jailbreak.

nerdtron123 on 30 Jan 2017

@nerdtron123 have you taken a look at #74?

timonline on 30 Jan 2017

@timonline please tell me where that shows how to run an SFTP server.
Appearently this error is coming from iOS sandbox.

scp works fine if you install scp. scp is not part of dropbear, this is not a bug.

Get scp from, for example, http://newosxbook.com/tools/iOSBinaries.html and install it to /usr/bin.

@nerdtron123, I was hinting to use SCP instead

@mologie, sigh as i said but @nerdtron123 wouldn't listen that it isn't related to issue in Yalu102

@timonline I really don't want to disturb anyone, but was dropbear removed in the recent beta 3? I can't ssh in (just ssh not sftp or scp). Using Nmap, I can see that my iPhone's port 22 is closed.

@warhouse512 in mterminal run "/usr/local/bin/dropbear -FRE" (no quotes) and then connect + tell me output

nerdtron123 on 30 Jan 2017

@warhouse512 not that I know of. Try rebooting and re-running Yalu102, worked for me when ssh was blocked

timonline on 30 Jan 2017

@timonline I had two parts to my question. So please be quiet.

@nerdtron123 classy. You realize i wasn't talking to you, right?

timonline on 30 Jan 2017

Also I implied I wanted sftp not scp

nerdtron123 on 30 Jan 2017

@timonline bye you're irrelevant you can't help me

@nerdtron123 no one probably will with that attitude. Psssst this is not a support forum, this space is for issues.

sigh

timonline on 30 Jan 2017

@timonline @nerdtron123 A reboot fixed it.. Sorry I did not want to cause any issues. Thank you both for the help!

@warhouse512 glad your problem was resolved.

I believe this should be closed but let's see what @kpwn thinks

I've also noticed that dropbear stops running after a while. Must be crashing.

keldegar on 30 Jan 2017

@keldegar nah, it's by design. (dropbear comes with a default session timeout of 3 consecutive)

See this #217

here's an sftp-server build for you guys fwiw, https://github.com/dweinstein/openssh-ios/releases. works on my device w/ yalu102 when put into /usr/libexec/sftp-server

HTH
