Curlftps return input/output error after mount remote file server with FTP/TLS explicit.
Tested on different servers, same result.


Reproducible: Always

Steps to Reproduce:
curlftpfs -v -o user=demo,ssl,tlsv1,no_verify_peer  ftp://test.rebex.net /mnt/ftp/
ls /mnt/ftp
ls: reading directory '/mnt/ftp': Input/output error


Server in example is public, you can use it to reproduce bug
(password = 'password')


curlftpfs -V
curlftpfs 0.9.2 libcurl/7.47.1 fuse/2.9
Comment 1 Sergei Trofimovich (RETIRED) gentoo-dev 2016-03-24 22:42:27 UTC
Tried to do the same on ftp://test.rebex.net. It works for me.
Slightly different versions of stuff here though.

$ curlftpfs -V
curlftpfs 0.9.2 libcurl/7.48.0 fuse/2.9

Let's try to look into what happens (added -d -f):

    $ curlftpfs -f -d -v -o user=demo,ssl,tlsv1,no_verify_peer  ftp://test.rebex.net test.rebex.net/

and run the 'ls' test. I hope curlftpsfs to log useful stuff.
Comment 2 Dblmok 2016-03-29 13:42:23 UTC
Reproducible: Always for background mode

-d      already implies -f

test with additional command line keys, test results:
"-d -f" ls worked
"-d   " ls worked
"-f"    ls worked
" "     ls return i/o error
Comment 3 Dblmok 2016-03-29 14:00:13 UTC
test with another server - test fail with both modes (background and foregrund)
log of another server:

curlftpfs -f -d -v -o user=XXX,ssl,tlsv1,no_verify_peer  ftp://XXX/ /mnt/ftpw

Comment 4 Sergei Trofimovich (RETIRED) gentoo-dev 2016-03-30 08:23:22 UTC
Does it work if you rebuild curl with USE=-gnutls?
Comment 5 Dblmok 2016-03-31 17:54:47 UTC
update curl to latest, same issue
curlftpfs -V
curlftpfs 0.9.2 libcurl/7.48.0 fuse/2.9


test different ssl libs, test results

gnutls, test fail:
* ALPN, server did not agree to a protocol
* GnuTLS recv error (-110): The TLS connection was non-properly terminated.
* Closing connection 0

Please reopen if reproduced for a server that we can access.
