Hi! Did somebody successfully upgraded an running 32bit system to 64bit? If so, what's the smartest way to do this? Thanks a lot Timo

You can just upgrade the kernel. If it's a 2.6 kernel with a 2.6 distribution, on 2.4 there were some hacks needed with modutils for this. A 32bit distribution works reasonably well under a 64bit kernel. One trap is that you need a 64bit iptables too if you want a working firewall (or use ipchains) Upgrading user land this way is probably not a good idea. If you want this I would rather install it into a new partition. They can run both in chroot under a 64bit kernel. However this is all not supported/tested by SUSE at all, so you're on your own. The easiest and safest way is to just reinstall. -Andi

I actually thought of a shell script that simply does an "rpm -Uvh" for all x86 RPMs...
I think one way could be: 1. Try to save as many important configs (actually the config-files) and try to save the whole home-dir 2. If you have compiled own programs try to save them (would be easy if they were RPMs) 3. Make an new partition and install a new 64bit Linux on it 4. Play back the configs an install your own programs (or better try to compile them 64bit) If I make a update to my system (say 9.1 to 9.2) it works fine. The differences between the Distro-Versions are not very great. If the KDE-MainVersion, glib and so on are the same it works fine. If not you have to configure some progams new. Martin

Hmm - this seems to be a rather local problem - we have lots of x86_64 machines here and all have working NIS. There is a problem with the Yukon Gigabit Ethernet Controller (eg. on ASUS A8V deluxe or ASUS D5000 Laptop), Which locks the machine hard upon mounting nfs shares. But this is resolved with newer kernels.

Well, you were absolutely right.... I have an A8V board with the Yukon chip.... now with the latest kernel it finally worked:-) Stefan Fent wrote:

<snip> Well, I'm sorry to disagree with you, but my A8V with kernel 2.6.8-24.11 -64 bits is still hanging when offering nfs shares and/or ftp service (vsftpd) thru the onboard Yukon/Marvelll chip. What I've noticed is when I initiate a data transfer from the 64bit box (for instance an ftp get -the 64bit machine is an ftp client to an other machine elsewhere) then afterwards this 64bit machine correctly offer nfs shares and ftp service to other computers. But if I reboot it, then try to mount the nfs shared offered by the 64bit machine from an other computer, then the 64bit machine is completely frozen... no luck for me... cheers, fabrice
