Public bug reported: Binary package hint: linux-source-2.6.15
I closed a file without saving, and needed to recover it. While looking around, I came accross this bit of information: http://www.novell.com/coolsolutions/tip/18724.html which tells you to copy /dev/mem to a file and use that file to find the lost file... Problem is: $ cp /dev/mem ./memory.bin cp: cannot open `/dev/mem' for reading: Permission denied which is nice I guess? but more problematically: $ sudo -i # cp /dev/mem ./memory.bin cp: reading `/dev/mem': Operation not permitted I would think root should be able to read and write anything in the computer, even if it may be a security concern or even if the action will break stuff... ** Affects: linux-source-2.6.15 (Ubuntu) Importance: Low Status: Unconfirmed ** Changed in: linux-source-2.6.15 (Ubuntu) Importance: Undecided => Low -- /dev/mem not readable to root https://launchpad.net/bugs/89583 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
