sysadmin@ubuntu /etc $ ls vsftpd*
vsftpd-users.db  vsftpd.conf  vsftpd.conf.backup


what is this vsftpd: vsftpd.pem part, and what does it mean? I never seen such before. does it mean that a file named vsftpd.pem exists in /etc ?

Which version of Ubuntu are you using? I am curious because I would like to know which version reacts like this from the ls command. – David Sep 18 '13 at 2:12

You have three files in /etc and one file in /etc/vsftpd/ that match the glob vsftpd*.
