Take the 2-minute tour ×  I recently setup VSFTPD on my personal
server for sharing files over FTP. In the vsftpd.log file, i see
hundreds of failed attempts to login with usernames like
"adminitrator" , "adminitrator1", "adminitrator2",
"adminitrator123" etc.  I am surprised because i just setup my
FTP server and i thought no one would know about its existence.
I did not communicate it to anyone that my FTP server exists.  I
guess with port scanning tools, one would have found FTP port is
open. However i wonder how one would have got my IP.    • I
downloaded a torrent file, would that expose my IP address?    •
Is it quite common for the attacker to harvest the ip address
from torrent trackers or some other service? Any idea how
attacker gets IP address? (like for spamming - spambots are used
to harvest the email ID)    • Any general pointers for a new
comer to secure the server (books, videos, totorials, blogs etc)
