Hi,

As far as I was able to look dropbear doesn't include sftp-server. So, what I did to get sftp working with dropbear was:

1 - uninstalled dropbear : sudo ipkg remove dropbear (FIRST enable telnet login, otherwise you'll be locked out of the router).

2 - installed openssh : sudo ipkg install openssh

3 - copy /opt/libexec/sftp-server to sftp-server.backup

4 - uninstall openssh : sudo ipkg remove openssh

5 - re-install dropbear : ipkg install dropbear

6 - patch /opt/sbin/dropbearmulti to enable access to /opt/libexec/sftp-server by following velovite instructions.

Probably it is not the most elegant solution to the problem but it worked.

Regards,

PVarela
