(Other stories by Matteo Dell'Omodarme)
"The aim of this article is to provide an introduction to some useful programs in the SSH suite, i.e. sftp, scp, ssh-agent and ssh-add. In the following we suppose that sshd2 daemon is well configured and running."
"Let's focus our attention on sftp and scp. The first one (Secure File Transfer) is a ftp-like client that can be used in file transfer over the network. It does not use the FTP daemon (ftpd or wu-ftpd) for connections, allowing a significant improvement in the system security. In fact, monitoring some logs file of our systems, we noted that about 80% of attacks in last month was against ftpd daemon. The use of sftp prevents all these tries since it permits to stop the potentially dangerous wu-ftpd."
"The second (Secure Copy) is used to copy files over the network securely. It is a replacement for rcp insecure command."
