So I'm pretty new to IIS and FTPS, tho I usually use ubuntu and vsftpd with sftp for secure file transfer. But in this case I was tasked with setting up a FTP server on a Windows server 2012 environment. Set up the user and FTP service and did a test transfer with WinSCP and FileZilla, so far so good.
But since some sensitive data will be transferred we needed encryption so I created a self signed certificate and set it to force encryption in SSL settings.
I tested the setup again and was able to log in. I could create directories and move files around. But when I tried to transfer files the transfer fails when the upload was finished with the message:
Using TLSv1.2, cipher TLSv1/SSLv3: ECDHE-RSA-AES256-SHA384, 2048 bit RSA, ECDHE-RSA-AES256-SHA384 TLSv1.2 Kx=ECDH Au=RSA Enc=AES(256) Mac=SHA384 Copying files to remote side failed.
Looking in the logfile I could see one entry with the filename of the file I tested a transfer on:
STOR aircontrol-v2.0-beta20.1631.160317.1513-win64.exe 550 2148074264 0 202 73855447 4570 1d3abd73-5c55-48c8-a3b5-63b6ca868863 /aircontrol-v2.0-beta20.1631.160317.1513-win64.exe -
And that's all to it. I tried to do the same with FileZilla and got the same results.
Is there anyone who has an idea what to do?
Thanks in advance!
