Curl (*nix) upload file to ASP.NET

I have an old redhat 8 box that I need to pragmatically send files to my webserver from. Disregarding the security issues with this, I've come up with the following way.

curl -F file=@<filename> http://webhost/reciever.aspx

The problem is, no matter what I try, the ASP.NET page is not accepting the file. What a开发者_高级运维m I doing wrong?

What version of ASP.Net are you posting too?

Normally ASP.net will check to make sure the form was visited before processing the postback. This behaviour can be disabled with enableViewStateMac="false" in the page declaration.
