CRC Transfer Integrity Check fails - Case sensitive?

[jimmi]

I am unable to transfer to or from a particular server - looking at the transfer logs it seems to be a CRC issue. Other servers work as expected.

When downloading, the requested file sits in the transfer queue retrying over and over again.

Uploads create a file named "filename.extension.bad" on the server, and also stay in the queue continually retrying.

If I recall I could dodge this issue in older versions of SmartFTP by skipping the transfer queue - presumably this also skipped the integrity check?

Details below.

Regards,

Jimmi

The XCRC reply from the server is wrong:
Wrong:
XCRC purchase.html
WRONG: 250 XCRC Successful. 9fe50fa1
CORRECT: 250 9fe50fa1

Please report the bug to the developers of the server product. In the meanwhile we are workign on a workaround. ETA: 1 day.

Please try it again with the latest version: https://www.smartftp.com/download

We have implemented a better detection now.

Excellent, it seems to be working fine now, thank you! Very speedy fix.

I'll try to find an email address for the "Titan/VisNetic FTP Server" developers and zap them a note... Although there's a good chance that the version running on this particular server is out-of-date anyway!
