TLS Renegotiation fails

Description (last modified by dkocher)

According to mod_gnutls documentation of ProFTPd, GnuTLS requires a TLS Renegotiation after 1GB of transferred data by default.


By default, mod_tls will perform renegotiations if supported, on the control channel after 4 hours, and on the data channel after one gigabyte of transferred data. The default timeout for a renegotiation is 30 seconds.

When transferring a single file larger than 1GB through ftps:// Cyberduck will cancel the tranfer reporting a permission error.

Expected behavior: Cyberduck should comply with the renegotation request on the TLS data channel

Workaround: Set TLSRenegotiate none in proftpd.conf
