Allowing the XCRC Command for Users

Although site-to-site transfers can expedite what otherwise could be a slow transfer, many administrators consider Site-to-Site transfers a security risk, exposing servers to "port theft" or "FTP by proxy" attacks. Depending on how your servers are configured, you might want to block these types of transfers.

Refer to File Integrity Checking (XCRC) for details of the XCRC command.

To allow or not allow integrity checking

1. Open the FTP Settings dialog box.

2. Do one of the following:

   • To allow transfers, select the Allow integrity checking (XCRC) check box.

   • To block transfers, clear the Allow integrity checking (XCRC) check box.

3. Click OK to close the FTP Settings dialog box.

4. Click Apply to save the changes on EFT.
