I suppose you do not run WinSCP from directory, where ida_dsa file is.

Hi,
I am having strange issue. i am trying to sftp a file from windows to linux server. i have got public key generated. When i run it using command line prompt it works fine. However when i am invoking the command line using perl script and passing encessary arguments sftp is not working . Kindly see log below. the perl script is being invoked by my id however file needs to be sent as process id. Any help is appreciaited
