Thank you all very much for all of your help. I think you've solved this one. I do _seem_ to be running a 32-bit system after foolishly using a 32-bit CD. But one small point: How can I get the system to report which type it is? uname -a does not seem to work.
> what does uname -a give out? I suspect on was 32bit and the other was > 64bit (amd64) On the known 64-bit system uname -a gives: Linux stewart 2.6.18-6-amd64 #1 SMP Sun Feb 10 17:50:19 UTC 2008 x86_64 GNU/Linux On the suspected 32-bit system with a amd64 kernel uname -a gives: Linux sdell03 2.6.18-6-amd64 #1 SMP Thu Apr 24 10:20:33 UTC 2008 x86_64 GNU/Linux which would seem to suggest that I'm running a 64-bit system. But on the same suspected 32-bit system with a k7 kernel uname -a gives: Linux sdell03 2.6.18-6-k7 #1 SMP Thu Apr 24 09:09:38 UTC 2008 i686 GNU/Linux Note the i686. So uname -a seems to give a kernel-dependent answer and not an answer dependent on which installer was used. uname -i gives "unknown". Which command should I use to report the system type and not the kernel type. I think "file" gives useful information. On the known 64-bit system file /lib/libc-2.3.6.so gives: /lib/libc-2.3.6.so: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.0, stripped but on the suspected 32-bit system file /lib/libc-2.3.6.so gives: /lib/libc-2.3.6.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), for GNU/Linux 2.4.1, stripped Is there another way? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
