I was asked to reconfigure and make some order in a FTP server which is operating on Ubuntu 10.04. I have root access to the machine.
When checking what server is running, I get:
# ps -ef | grep ftp root 2287 1 0 Mar19 ? 00:00:00 /usr/sbin/vsftpd root 26380 26369 0 Jun27 ? 00:00:02 /usr/lib/openssh/sftp-server
From the man pages I understand that
sftp-server are both FTP server software. How can I tell which server is actually serving an FTP request from a remote machine?
