This comment in the code explains it:



     /* Determine if server can respond to REST command and therefore

        whether it supports range */



I'm assuing you ased for a "NOBODY" transfer.



> Lib curl version : 7.21



Approaching six years old: "curl version 7.21.0 was released on June 16 2010.

The following 18 security problems are known to exist in this version."

            Yes we used no body request.

                        curl_easy_setopt<http://ncvs.commvault.com/source/s?defs=curl_easy_setopt&project=win>(m_curlContext<http://ncvs.commvault.com/source/s?defs=m_curlContext&project=win>->m_curl<http://ncvs.commvault.com/source/s?defs=m_curl&project=win>, CURLOPT_NOBODY<http://ncvs.commvault.com/source/s?defs=CURLOPT_NOBODY&project=win>, 1L);
            curl_easy_setopt<http://ncvs.commvault.com/source/s?defs=curl_easy_setopt&project=win>(m_curlContext<http://ncvs.commvault.com/source/s?defs=m_curlContext&project=win>->m_curl<http://ncvs.commvault.com/source/s?defs=m_curl&project=win>, CURLOPT_HEADERFUNCTION<http://ncvs.commvault.com/source/s?defs=CURLOPT_HEADERFUNCTION&project=win>, getContentSize<http://ncvs.commvault.com/source/s?defs=getContentSize&project=win>);
            curl_easy_setopt<http://ncvs.commvault.com/source/s?defs=curl_easy_setopt&project=win>(m_curlContext<http://ncvs.commvault.com/source/s?defs=m_curlContext&project=win>->m_curl<http://ncvs.commvault.com/source/s?defs=m_curl&project=win>, CURLOPT_HEADER<http://ncvs.commvault.com/source/s?defs=CURLOPT_HEADER&project=win>, 0L);

            It’s not happening in all machines. In our test machines server responds for REST 0 command.
            Server IP used in both machine is same

                        5632 1604 04/20 04:38:10 6055 0000: REST 0
5632 1604 04/20 04:38:10 6055 <= Recv header, 70 bytes (0x46)
                        5632 1604 04/20 04:38:10 6055 0000: 350 Restarting at 0, Execute get, put or append to initiate tran (In our test machine)

            And I doubt if any Anti-Virus blocking the FTP REST command on the client side. There are few AVs does that.

Subject: Rest 0 command not supported

Hello team ,

We are facing this error while getting the size of a file . Why do we need REST 0 command after size ?

REST command is not supported by server ? Or we have sent REST command in a place where it should not have ?

 Please let me how to proceed here .
Lib curl version : 7.21

4004 1fa4 04/19 15:52:16 104 0000: SIZE WinX64_11.0.0B80-SP3_SP3-HotFix-102.exe
