3.40.0 SSL error with proftpd

#1 Post by paul-ifdnrg » 2019-01-29 15:36

Hi,
I was seeing "error setting read fd 19 TCP_NODELAY 1: Connection reset by peer" and accompanying failed transfers using 3.40.0.

The error did not show up when allowing Plain txt. and additionally does not show up when downgrading to 3.39.0.

Server is proftpd-1.3.6 under FreeBSD
OpenSSL 1.1.1a-freebsd

What does it say in the log of FileZilla?

Hi,

I see similar issues: Filezilla 3.40.0 can not connect to pure-ftpd with tls.
Filezilla 3.39.0 works fine with the same pure-ftpd and tls. Plain text works fine with Filezilla 3.40.0

System:
12.0-RELEASE-p2 AMD64
OpenSSL 1.1.1a-freebsd
pure-ftpd-1.0.47

Not at all similar. This topic is about proftpd, not pure-ftpd.
