i386 or amd64?

[Lakeside5]

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:

cat /proc/cpuinfo

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

K, thanks a lot I have the terminal info, so I'll check out Wikipedia now.

Since you mentioned uname... if you can use

uname -m

that will tell you. x86 means i386 x86_64 means amd64

May I ask how your pc was hacked?

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.

Ozymandias_117 thanks, that worked! It says i686, so I should install what then? Thanks

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
