small files corrupted with TLS

[Igor]

Hi,

I can't transfer very small files. On the server they are 0 bytes. I would like to enable the SFV-feature of the server. To do so, I have to transfer the small sfv-files with 122 bytes or 600 bytes first. But the server receives only 0 bytes

Auth TLS, secure file transfers
Client: FlashFXP 2.1 Build 924, WinXP prof.
(same problem with v2.2 Beta 937)
Server: BlackMoon FTP-Server v2.7 Build 1691, WinXP prof.

With SSL impl. and RaidenFTP the small files are ok, but then I get corrupted (smaller) files after download

Any hints are welcome.

I'm registered user of FlashFXP.

Bye,
Igor

I tested SSL/TLS on glftpd and serv-u with small files and I was unable to reproduce the problem.

I don't happen to have a external RaidenFTPD or BM FTPD server for testing. RaidenFTPD worked fine running on my local machine.

Hi Bigstar,

that is the answer I've feared

First the SSL transfers with RaidenFTP result in incomplete files. That was reproducable by other users. I 've tested UltraFXP and this client doesn't has such problems with SSL transfers.

Then I used BlackMoonFTP, because of RaidenFTP often crashes. That server cannot authenticate with SSL impl, so I choose auth. TSL. I was curious The download works fine with FFXP, no corrupted files. But now I encounter problems with small files (btw, they are smaller than the upload block-size).

Would it be helpful, if I make an account for you on my server ? Then you can test it shortly an see, what I mean.

Maybe the error is server based. But do you know a well working FTP server, with SSL/TLS, stable and fast ?

Bye,
Igor

Hmmm

Sure if you set me up an account i'll be happy to look into it.
