How do i setup, configure and secure a sftp server?

[TechTinkerer]

Hi,

Can anyone help me with settingup a sftp server with configuring, securing it and replacing dropbear with it please?

All i have done is install the opkg sftp server...

Thanks guys, you're awesome

The default ssh setup works with scp.

The default ssh setup works with scp.

I know, but app support especially with scp is missing on android....as i want to be able to see file tree and copy\paste scripts etc

opkg install openssh-sftp-server

That's it. Nothing else is required.

opkg install openssh-sftp-server

That's it. Nothing else is required.

Not even changing default ports, adding certs etc? any idea where the conf is stored for the server settings?

Sorry, I missed the part where you said you wanted to replace dropbear. I'd guess you'd also have to install openssh-server. Personally I wouldn't bother as dropbear is pretty secure. It'll just use the usual key setup on the router.

Thanks for this info. Do I need to restart the router after installing openssh-sftp-server

Sorry, I don't know whether that's necessary. Do it anyway.

No need to restart the router after installing sftp server.

thanks all. So I have installed and restarted but I still get the same issue when I try to connect to the router using cyberduck using a sftp connection on port 22.

The error in my syslog (before and after installing) is

dropbear[4923]: Exit before auth from <192.168.xx.xx:58824>: No matching algo kex
