SSL-ciphering command channel ONLY via AUTH TLS won't work

Help & Support

Hi,

my provider has pureftp with the possibility to use ftp with SSL-ciphering command channel ONLY via AUTH TLS . The command channel is secure, the data channel not. In FlashFXP or FIlezilla I have no problems to use this feature, with dopu 9.1 I can't use it. It seems to me, that dopus only support full secure data channels:

SSL_connect:CTRL error in 3RSH_A SSLv3 read server hello A [DATA: TLSv1/SSLv3, cipher AES256-SHA, 256 bits] SSL DATA connected --> LIST -alF 150 Accepted data connection 226-ASCII SSL_connect: 4096 SSL_connect:DATA error in 3RSH_A SSLv3 read server hello A RecvList() - WSAECONNRESET: Connection reset by peer FD_CLOSE - WSAECONNABORTED: Software caused connection abort SSL_connect: 4096 SSL_connect:DATA error in 3RSH_A SSLv3 read server hello A 226-Options: -a -F -l 226 25 matches total --> LIST -alF Timeout bei Befehl 1017

Will this problem be fixed? My Provider will not allow ciphering the full channel, because he can't calculate transfer rate for his tarifs.

Thank you

If you want a feature adding to the FTP client you should contact GPSoftware directly via their support form:

(Seems odd that an ISP can't count encrypted traffic!? But I guess you can't do anything about that and it's better than nothing to encrypt the login/password, so fair enough.)

I'm not sure if it would work or not but you may be able to work around the problem by using STunnel or a similar proxy to create an SSL proxy for the command connection while leaving the data connection to connect normally. Could be complicated to get working, though...
