posted March 10, 2006 6:20 PM Hi, I am trying to connect to a secure FTP server through Explicit TLS/SSL authentication using the listview sample. I get a message "Token supplied to function is not valid". Following is the log I see:- *************************************** Connecting to 192.168.21.106... 220 GlobalSCAPE Secure FTP Server (v. 3.1) * UNREGISTERED COPY * AUTH TLS-P 500 Protocol not supported.

posted March 13, 2006 5:12 PM Hi Srikanth, When I tried setting Security to Implicit or ExplicitControlOnly, it worked ok. For Explicit, I actually had to send a couple of commands before performing the List. If you add code to your project to do the following: ftp1.Invoke(FtpCommand.Null, "PBSZ 0"); ftp1.Invoke(FtpCommand.Null, "PROT P"); prior to any listing or file transfer, it should work ok. Hope it helps, -ken |
