Thanks Dan.



As per your suggestion got rid of all -Q options. Now my command & logs looks like this -



$ curl --verbose --proxytunnel -x proxy.xyz.com:80 -T abc.txt ftps://xxxx:xxxx_at_ftpssl.rbc.com/inbound/abc.txt

Segmentation fault



Good thing is I see its trying to establish a data connection for FTPS on a random port in 6200-6299 range(as Windows based client does), but STOR abc.txt is not passed & ultimately its giving “Segmentation fault”.



Can you please advise if any further modifications are required in my curl command to make this work? Thanks.

Why are you setting all those -Q options? All those commands are sent by curl

itself automatically, and their presence is confusing curl's internal state

machine. Remove them, change the URL to

ftps://ftpssl.rbc.com/inbound/abc.txt and add the option -T abc.txt (to specify

the uploaded file name) and you should see much better results.
