** [bugs:#1296] Win: ftp over http proxy throws error ONLY IF --verbose is omitted**
**Status:** pending-needsinfo
**Labels:** proxy http ftp windows build 
**Created:** Wed Nov 06, 2013 11:35 AM UTC by Sebastian Stammler
**Last Updated:** Wed Nov 06, 2013 11:35 AM UTC
**Owner:** Daniel Stenberg
Applies to Windows static builds.
I want to use curl at my work (have to work in a windows environment here...) to access a FTP server through a HTTP proxy (only a http proxy is available). The odd thing is that this actually works (using the -p or --proxytunnel option) when the --verbose flag is used. If omitted, the error
> curl: (55) Send failure: Socket is not connected
is thrown.
**Invocation**
> curl --proxy 'http://proxy.firm.net:8080'  --user 'ftpuser:ftppass' 'ftp://random.ftpserver.com/' --ftp-pasv --disable-epsv -p --verbose
works, withouth *--verbose*, the above error is shown.
**curl -V**
>curl 7.33.0 (i386-pc-win32) libcurl/7.33.0 OpenSSL/1.0.0k zlib/1.2.8
>Protocols: dict file ftp ftps gopher http https imap imaps ldap pop3 pop3s rtsp smtp smtps >telnet tftp
>Features: AsynchDNS GSS-Negotiate Largefile NTLM SSL SSPI libz
I also tried the 64bit version, same story.
Cheers and thanks!
