Am I running 64 bit linux?
 
I installed Centos from what is supposed to be the 64 bit DVD but when doing an rpm -qa I see no indication that any of the RPM's are 64 bit.

Not sure how I can actually check whether my OS is 64 bit?

Thanks

uname -a should tell you what your kernel you're using.
ldd libc.so should tell you what the core of the system is compiled for.


Cheers,
Tink

Yeah that looks good:

2.6.9-42.0.3.ELsmp #1 SMP Fri Oct 6 06:28:26 CDT 2006 x86_64 x86_64 x86_64 GNU/Linux

Just weird that none of the RPM's have a x86_64 to em, will yum by default be upgrading to 64 bit rpm's?

Thanks
