Notes
•
This block utilizes FTP, not SFTP as SSL is not currently supported in the firmware. As a result, all FTP
traffic sent and received (e.g. username, password, file data) is sent unencyrpted in plain text and is
therefore visible to anyone with access to your internal network. However, this should not be a problem
so long as the data you are sending is not of a sensitive matter and your FTP server account is
CHROOT'd properly (talk to your IT professional about using FTP).
•
It is suggested that your FTP server either have a internal/external domain name OR use a static IP
address as a change in address will prevent the block from transferring files. See "Setup" for more
details.
•
Your FTP user account for this block must have "Write" privileges to be able to write files to the server.
Optionally, your account may also have "Append" privileges. Note that if your destination files already
exists and your user only has "Write" then the file will be overwritten. If the file exists and your user
has "Append" then the file contents transferred will be appended to the existing file.
