Chatalyan, and i think that I discovered a bug or design flaw... and I don't know that it is provide from kernel... Let's see: (1) I mount /tmp with noexec,nosuid,nodev options /dev/hda6 on /tmp type ext3 (rw,noexec,nosuid,nodev,relatime) (2) I went to 'cd /tmp'`and I created a bash script, or another script (perl, python, etc)... and chmod +x createdfile script cointain: #!/bin/bash echo "Probe..." (3) I tried to execut it with "./createdfile" [kehcho@...cho] [/tmp]$ ./createdfile -bash: ./createdfile: /bin/bash: bad interpreter: Permission denied (4) I tried to execute it, but pass to bash ". /tmp/createdfile" [kehcho@...nadowt] [/tmp]$ . /tmp/createdfile Probe... It is a kernel bug or I just report a another one?
