A protein's structure determines its function. For instance, structural proteins such as collagen and keratin are fibrous and stringy. Globular proteins like hemoglobin, on the other hand, are folded and compact. Hemoglobin, found in red blood cells, is an iron containing protein that binds oxygen molecules. protein's structure determines its function.

So I assume your question is how to transfer file to a server installed with Apache2 with SFTP. First of all, you need SSH server installed to enable SFTP.You can verify if SSH server is installed with dpkg-s openssh-server. If it is not installed, please install it sudo apt-get install openssh-server. See more information on how to install OpenSSH Server at the other post.p vote 0 down vote.

SSH2 is no longer free software like SSH1; the developer of SSH2 has restricted the free use of SSH2. Unlike SSH1, SFTP (Secure File Transfer) program has built in to SSH2 package and it uses the same Encryption protocols used by SSH2, to encrypt data streams.SH-USERAUTH: It is the protocol used for user authentication at the communication establishment. This protocol authenticates SSH client in SSH server. This protocol also runs over the transport layer. SSH-CONNECT: It is the connection protocol which multiplexes encrypted data into some logical streams.
