I have a excel file on linux machine. I am accessing the excel file from a windows client machine using IE browser... like

<iframe src="linuxmachine:9081/wps/Total.xls">. It is not displaying the excel file.
It is saying ms0xx.xls is read only and could not access the file.

I verified all the mime types in server and on linux too. it is all correct.
Can any body tell how can i access excel file from linux server?
