Generally, 'uname -m' should report x86_64 for 64-bit (amd64) and i686 for 32-bit (x86). While it is possible to have a 64-bit kernel and 32-bit userland, the reverse is not possible. So another check can be 'file /sbin/init' which will report as something along the lines of "/sbin/init: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, stripped" Regards, Ron
