If I understand the situation, you have a system occupying 1.5 Gig and you want this partition cloned exactly onto the other? This 1.5 gig should tar onto a single CD if you use bzip2 compression (gzip probably would do it). this scenario should do it.. cd / tar -cjf image.tar.bz2 / You then need to burn this file onto a CDrom, take it home, clean the partition - probably use mke2fs (or whatever filesystem you use). Then cd onto that partition and extract the image file. You'd need to do some editing of fstab, and the like. I believe you said this system uses grub? I don't use grub, so I don't know about that aspect. If the kernel filename is the same, it might simply boot up as is, or you might have to do some editing. But at any rate, that ought to at least get your files placed where you want them. In addition to this, of course, to extract the image onto the destionation system, you'll need linux to extract onto the partition - either a rescue disk or Knoppix or the like. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Okay, leave your desktop system at work:-) For this you need broadband. Run vncserver on your peecee at work. It can run whatever distro is best for work. Or several. At home, connect with vncviewer. You can bring up a full desktop over the Internet. How well it will work depends on how good a screen you need: it probably won't suit a graphics specialist, but for ordinary programming or system admin its fine. You can choose pretty much any screen size you like: your choice will be governed by your screen at home and the bandwidth requirements. You can run several desktops of you want. On the same or on different remote computers. The nicest way to access machines at work from home or vice versa) us with a VPN. For that I recommend openvpn. It's a Debian package, it uses UDP (so doesn't get the timing problems of TCP VPNs), uses adaptive compression, uses encryption for security. And it's easy to set up. There are alternative related plans: filesharing with NFS across the VPN (not good for home directories, but probably good for getting the results back to work). If you don't want a GUI, then a modem works quite well: it's what I'm doing at present. -- Cheers John -- spambait [EMAIL PROTECTED] [EMAIL PROTECTED] Tourist pics http://portgeographe.environmentaldisasters.cds.merseine.nu/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Whether you want compression depends on CPU power, network speed and your patience. In general, you _can_ also use dd in like manner. As I recall, you need to e2fsck e2resizefs dd e2fsck However, best not to do this with filesystems mounted rw. A challenge to anyone who says dd won't work: try it. I have done it, on different-sized partitions. Worked fine for me. However you get the data across, you then have to (re)install your boot mangler Reconfigure /etc/fstab Reconfigure /etc/network/interfaces Maybe, reconfigure your modules selection such as for your network card. -- Cheers John -- spambait [EMAIL PROTECTED] [EMAIL PROTECTED] Tourist pics http://portgeographe.environmentaldisasters.cds.merseine.nu/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
