Adding sshfs support to dropbear?

[zerophase]

I'm trying to add sshfs support to dropbear, by compiling openssh-sftp-server into it. I'm following this guide, but it seems like the environment is a bit different for Merlin. I get to this point with the perl compiler.

perl -pi -e 's/\/usr\/libexec\/sftp-server/\/opt\/libexec\/sftp-server/g' dropbear[\quote]

But it either doesn't add the functionality since usr/libexec/sftp-server doesn't exist on the box, or I'm still using the version of dropbear that comes with the router. (When I check the ssh process it shows a version from a year ago)

Anyone able to help out?

Setup Entware here:

Then:
opkg update
opkg install openssh-sftp-server

I installed openssh-sftp-server to the router. I need to compile it into dropbear, to get sshfs support. So, what commands do I need to run while modifying dropbear?

Simply compile it and copy it to the right path.

The compile commands that tutorial gives aren't correct for Entware. There isn't a /usr/libexec or sftp-server reference on the machine outside of /opt/libexec. So, I think I need to run different compilation commands. (I'm not all that familiar with perl)

How would I go about updating the machine to use a more recent version of dropbear? I installed it from opkg, but the system still runs the older dropbear.

I thought you were refeering to ASUS FW not Entware.

Don't I have to get it to work with both Merlin and Entware?

Are you using WinSCP for the client? If dropbear is running and you've installed openssh-sftp-server, it should work automatically.

 

[hggomes]

If you use WinSCP you can login to SSH Servers via SCP protocol not SFTP, you need sftp-server from OpenSSH to make it work together with Dropbear SSH server to work with SFTP protocol.

It's just the backup solution I'm using for now needs to be able to remotely mount drives.
