How to fix a scheduled report to be saved to file location accessible outside of Cognos which is on Linux?

How to fix a scheduled report to be saved to a file location accessible outside of Cognos?  Have a scheduled program running  but need the output written to a file location outside of Cognos where it can be accessed with a program that will format and ftp it to an outside source automatically.  Found IBM document which says to create a shared folder in Windows, but process won't work in a Unix or Linux environment.  Lucky us, we are on Linux server and our Cognos Administrator says it can't be done.  Anyone found a solution or a work-around to this?
