http://askubuntu.com – I am using Ubuntu 11.10 and wish to simply know whether I can dump all physical memory and swap, as due to some kernel restrictions, I can't dd /dev/mem, even as superuser. Is there any workaround or option to allow dd'ing /dev/mem or a dedicated tool made to do this correctly? (HowTos)
