Editing PHP5.INI file on asphostportal.com Linux Hosting

I need to edit the PHP INI file my asphostportal Linux Hosting Account.

I have located the file using SSH, I am able to download it but when I upload the edited file, I get Permission Denied.

I googled it out but can't find a solution. Found a blog 9 months old whining about exactly the same problem but no answers.
