SFTP (Secure File Transfer Protocol) With Dropbear


Configure Dropbear SSH server

SSH server can’t work independently, it require SSH server (like dropbear) to run. Dropbear require libz & libcrypto to run, so please first install them (if not install already). To install the dropbear SSH server, follow the steps given below.

-bash-3.2# tar –xvf dropbear-0.52.tar.bz2

-bash-3.2# cd dropbear-0.52

-bash-3.2# ./configure

-bash-3.2# make PROGRAMS=”dropbear dbclient dropbearkey dropbearconvert scp”

-bash-3.2# make PROGRAMS=”dropbear dbclient dropbearkey dropbearconvert scp” install

It will install the dropbear SSH server. Now you can create the softlink of dbclient as ssh. It is not mandatory, you can also use dbclient instead of ssh command.

-bash-3.2# ln –s /usr/local/bin/dbclient /usr/bin/ssh

To start the dropbear SSH server, first create the dss & rsa keys (for the encryption of SSH packets) in /etc/dropbear directory. SSH server does work without encryption, so it is mandatory to create the keys.

-bash-3.2# dropbearkey –t dss –f /etc/dropbear/dropbear_dss_host_key

-bash-3.2# dropbearkey –t rsa –f /etc/dropbear/dropbear_rsa_host_key

Now dropbear can be started simply by following command.

-bash-3.2# dropbear

If above will done properly you can connect your system via SSH.
