It was changing the permissions from 444 to 400. I got thrown off because the initial post of this thread stated this was related to the /dev/mem debate btw dev mem is not 444, but crw-r----- 1 root kmem, therefore normal user has 0 permissions which is a little different. . >> For files in the /proc file system, it is not that simple since they need to >> have a function to handle the write request. The files are actually all char devices not proc, but I still get your point. Changing 444 to 400 makes a lot more sense to me than the /dev/mem debate.
