Turning internal hard disk into external

Hi there,

I'd like to know if there is a software or a distro which does the following:

Imagine having two PCs. What the software should do is allow to turn one PC's hard disks to be accessed as external hard disks. It would be great if I could tell which USB port and which hard disk should be accessible like this. Now when everything is selected properly one could just plug in the other PC's USB cable and have access to the selected drive.

Is there something like this ?

Welcome to linuxQuestions.
One can not directly connect two PCs together with a regular USB cable. However, there are special USB file transfer cables that can be used to create a network but it is easier just to connect them via an ethernet cable. Older hardware requires what is called a ethernet cross over cable to directly connect two PCs together.

All distributions can configured for network file sharing and there are several ways. nfs, SMB (samba), sshfs

I know that there are a lot of possibilities to configure network file sharing under linux. However what I am after is a simple way of not doing the whole configuration thing. Something like: "insert CD to boot from, select drive for sharing access, connect to this drive via USB" and that's all. Why I am specifically asking for USB is that the whole system should act as an external hard drive. Hope that makes it any clearer what I am looking for.

On the Mac, that's referred to as booting in target mode. Using that as a google search along with linux turns up no positive answers. This page says there is no such thing for PCs, but gives an idea how it would be done if you want to try some hacking.

Thank you! That was exactly what I was looking for! Too bad this doesn't exist as a linux feature. I wish this was on someone's to-do list.

aka BKO, not quite what you're after but one option. I just use external drives as external drives. Replication across drives is pretty brain dead in linux and it doesn't take much space (relative to capacity) to have a bootable distro.
