I have a Ppro/180 (overclocked to 200MHz) too. What about players? Xmmx is graphical and I'm not familiar with CLI or block-graphics players others than those that were big with OS/2 Warp 3 and 4 more than a decade ago.

Something just occured to me on this this... Suppose I have an old Amd 486DX2/40, could this oldie be setup so that it boots a minimal (blocky) GUI over NFS to be able to run xmms or something like that?

NFS is the traditional diskless workstation method, as used by Sun for the past 2 or 3 decades. The efficacy of it is very dependent on what you're doing. Web browsing, reading email, running the odd program; people won't notice. High I/O intensive applications... not suited for diskless in the first place! The key is mostly sufficient memory so that the machine doesn't swap and can keep commonly accessed programs in I/O cache. -- rgds Stephen ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos smime.p7s Description: S/MIME cryptographic signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Yup! (That's also true for diskful machines). -- rgds Stephen ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

> 1. Should I just do iSCSI backed diskless setups? Probably doesn't scale well. What's wrong with NFS? You can even have root on NFS these days A quick google found: http://www.digitalpeer.com/id/linuxnfs My first thought: Install a workstation as normal, then tar/untar them onto the NFS server. With some correct seperation of files you should be able to share most of the filesystem between machines (eg /usr could be readonly). You might even be able to make root readonly, but I've never tried that. -- rgds Stephen ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Booting Diskless Workstations
I made a post in the Fedora list that didn't yield much help regarding this. I need to use a CentOS5.1 server to remotely boot a few Fedora 9 workstations. I have the option of using straight PXE, or even reflashing gPXE to the LOM for the clients. What I am interested in knowing is the best approach to this. 1. Should I just do iSCSI backed diskless setups? Probably doesn't scale well. 2. I looked at ltsp, but I can't present a fc9 environment with a RH5.1 server? The workstations would be fairly stateless, I intended on redirecting home dirs to a persistent share that gets backed up. Any ideas I can look into would be greatly appreciated!
