Re: CRC vs SSH

How can I set the WINSCP to make it always CRC checking and in case of some error - automaticaly repeat the file transfer? In my case I have to repeat manually many (5 - 10) times to make the transfer error-free.

WinSCP does not have such feature.
It's tracked here:
https://winscp.net/tracker/374
As mentioned there, even if this was implemented, majority of servers won't support it anyway.

While SSH guarantees that all packages sent are accurate, it does not guarantee that the entire file was sent. That's why you still need CRC.

Re: SFTP checksum bug fix?

Bug fix: Checksum calculation with SFTP protocol was not working at all.

This is unrelated to your first question. There was a bug in file checksum calculation that can be requested from Properties dialog. This has nothing to do with SSH session integrity checking.

1. When running in batch mode am I use SCP SFTP mode?

Depends on your settings.

2. Was this error present in 3.8.2?

The feature mentioned above was added in 4.0 beta.

SFTP checksum bug fix?

I noticed the following bug fix in the history:

Bug fix: Checksum calculation with SFTP protocol was not working at all.

Two questions:
1. When running in batch mode am I use SCP SFTP mode?
2. Was this error present in 3.8.2?

Thanks

Re: Does winscp3 have CRC checking

SSH protocol have built in integrity checking, hence file cannot be corrupted while transferred.

Does winscp3 have CRC checking

How does WinSCP3 guarantee that the file being transferred in not corrupted while in flight. Is there integrity checking that is occurring on the fly?
