Enable No Execute (NX) protection on Amazon AMI

by egulik1 - 6/21/13 12:55 PM

Hello,

I'm build amazon micro instance based on Amazon Ec2 AMI and I have kernel version:

- 3.4.43-43.43.amzn1.x86_64

[CODE]

# $ s cat /proc/cpuinfo

processor : 0

vendor_id : GenuineIntel

cpu family : 6

model : 26

model name : Intel(R) Xeon(R) CPU E5507 @ 2.27GHz

stepping : 5

microcode : 0x11

cpu MHz : 2266.746

cache size : 4096 KB

physical id : 0

siblings : 1

core id : 0

cpu cores : 1

apicid : 0

initial apicid : 6

fpu : yes

fpu_exception : yes

cpuid level : 11

wp : yes

flags : fpu de tsc msr pae cx8 sep cmov pat clflush mmx fxsr sse sse2 ss ht syscall nx lm constant_tsc up rep_good nopl nonstop_tsc pni ssse3 cx16 sse4_1 sse4_2 popcnt hypervisor lahf_lm dtherm

bogomips : 4533.49

clflush size : 64

cache_alignment : 64

address sizes : 40 bits physical, 48 bits virtual

power management:

[/CODE]

What I'm trying to figure it out is to how enable NX(No Execute) Protection on that virtual instance. I tried installing pae kernel but it looks like package is not found for this distro.

I think it might be something related specifically to that AMI and maybe someone had an issue like that in the past, so any input is appreciated.

Thanks !!
