Has anyone seen or know what is causing this FTP log file line-item?
3 times when I successfully logged into FTP today, the log file shows a server response of a wrong password (530) to an IP address that is not mine... Below are FTP Log-file entries. I have removed my username & IP address:
[2009/09/01 09:46:28] my_username 75.MY.IP.XXX: C="USER my_username" B=- S=331
[2009/09/01 09:46:28] my_username 74.9.212.42: C="PASS (hidden)" B=- S=530
[2009/09/01 09:46:30] my_username 75.MY.IP.XXX: C="PASS (hidden)" B=- S=230
[2009/09/01 09:46:30] my_username 75.MY.IP.XXX: C="FEAT" B=- S=211

[2009/09/01 10:13:39] my_username 75.MY.IP.XXX: C="USER my_username" B=- S=331
[2009/09/01 10:13:39] my_username 206.174.127.8: C="PASS (hidden)" B=- S=530
[2009/09/01 10:13:41] my_username 75.MY.IP.XXX: C="PASS (hidden)" B=- S=230
[2009/09/01 10:13:41] my_username 75.MY.IP.XXX: C="FEAT" B=- S=211

[2009/09/01 10:28:15] my_username 75.MY.IP.XXX: C="USER my_username" B=- S=331
[2009/09/01 10:28:15] my_username 69.229.165.99: C="PASS (hidden)" B=- S=530
[2009/09/01 10:28:17] my_username 75.MY.IP.XXX: C="PASS (hidden)" B=- S=230
[2009/09/01 10:28:17] my_username 75.MY.IP.XXX: C="FEAT" B=- S=211

Line 1: server acknowledges good username (331) from my IP address.
Line 2: always at the same time stamp, the server tells someone else's IP address (associated with various ISPs around the country) that the password was refused (530).
Line 3: a few seconds later, the password I sent is accepted (230) from my IP address.
Line 4: my FTP client successfully starts its session...
Any ideas what's causing this would be appreciated!
Thank you.
