    i386 or amd64?

    I have to install my ubuntu server again ( I was hacked, so replacing the Intrepid Ibex with Lusty Lynx) and have to do it from a usb flash drive as my cd rom doesn't work. I need to know if my system is amd64 (which I think it is, it was built from scratch about 4 years ago or i386. Entering 'uname -r' just gave me numbers like 12.?.? (sorry didn't write it down, now I'm on the Windows computer. But it didn't show amd64 or i386 so I'm wondering how to find out. Thanks

    Look up your CPU on Wikipedia to see if it's 64-bit capable.

    If you don't know the model number of the CPU, look at the command:

    Code:
    cat /proc/cpuinfo
    If it supports 64-bit, and you've got a gigabyte of RAM or more, then install the amd64 version.

    I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.

    Since you mentioned uname... if you can use
    Code:
    uname -m
    that will tell you. x86 means i386 x86_64 means amd64

    Sorry, for posting all this but, srufing Wikipedia was confusing so.. Does that mean I have amd64, and that I have 3.2GB RAM? Thanks.

    Well teeedubb just my own stupidity, probably I allowed a Joomla vulnerability to be exploited, or listened to someone who suggested 'sudo -i' (as sometimes no matter what I did I couldn't seem to change permissions) and that did the trick but..allowed someone to take over my root I think.

    It is an Intel Pentum (i586), so you would use *386 iso images. 64-bit is solely for machines with AMD CPU's

    No it isn't... Intel makes 64-bit CPUs as well... Their late p4s and newer are all 64-bit
