Hi,
FTP over SSL does not work with curl 7.21.0 and 7.20.1 when using the
multi interface. It kind of crashes during ssl negotiation.
The following code should reproduce the problem:
int main(int argc, char ** argv)
{
int running;
CURL* hnd = curl_easy_init();
CURLM* multi = curl_multi_init();
curl_easy_setopt(hnd, CURLOPT_VERBOSE, 1L);
curl_easy_setopt(hnd, CURLOPT_URL, "ftp://wtest.uni-rostock.de/";);
curl_easy_setopt(hnd, CURLOPT_FTP_SSL, CURLFTPSSL_ALL);
curl_multi_add_handle(multi, hnd);
do
{
curl_multi_perform(multi, &running);
} while (running > 0);
curl_easy_cleanup(hnd);
curl_multi_cleanup(multi);
}
Which gives the following output:
* About to connect() to wtest.uni-rostock.de port 21 (#0)
* Trying 139.30.8.42... * Connected to wtest.uni-rostock.de
(139.30.8.42) port 21 (#0)
< 220-wtest.uni-rostock.de X2 WS_FTP Server 5.0.5 (3210201760)
< 220-********************************************
< 220-FTP-Zugang zur Aenderung der WWW Seiten
< 220-********************************************
< 220 wtest.uni-rostock.de X2 WS_FTP Server 5.0.5 (3210201760)
> AUTH SSL
< 234 SSL enabled and waiting for negotiation
* successfully set certificate verify locations:
* CAfile: none
CApath: /etc/ssl/certs/
> USER anonymous
< JFLSU
And then outputs a lot of garbage and loops forever.
Could that possibly have to do something with the change "superfluous
blocking for OpenSSL-based SSL connects and multi interface" in 7.20.1?
Thanks,
Georg
