Our customers compress files with gzip and upload it via ftp. They all use the same script which forces the ftp in binary mode. Sometimes we cannot decompress the received files anymore: we receive following error: invalid compressed data --crc error. When they recompress and reftp the file, sometimes it works the second time. Any ideas out there what may be cause this error?

gzip crc error
- Thread starter Patten
- Start date
The first step would be to save a 'bad' file which fails CRC, and a supposedly identical 'good' file which has no CRC errors.
Then use the [tt]cmp[/tt] utility to find out what the actual differences are.
Once you know what the differences are, then perhaps you can figure out how those changes came about.
Perhaps it fails to go into binary mode on occasion?
Is there any way of making the FTP transfer verbose, and logging what goes on?
