They boot after 1 switch, though. Gbits clients boots it without prob?s after 2 switches. All the wiring is cat6, and the switches are brand new gbit. This is worrying me. In a large setup you have to count to at least three switches between the clients and the server. I haven?t tried three switches yet with gbit clients. In many school environments you ?ll need three switches, even four, and you can hardly expect all clients to be gbit. Core switch(-es), floor switches, classroom switches Comments?

Could it shutdown when booted in nfs mode? I cannot reproduce a shutdown failure here. It is possible that your hardware is at fault. Maybe 10% of my thin client hardware has trouble like this.

Warren Togami wtogami at redhat.com What?s the ubuntu approach? Did they solve it? I remember I tested it some 1/2 year ago, and I think it was the same problem then. But they might have got further now? About iScsi: I think it is different if you use iScsi with a HBA or not. The HBA firmware will keep the block device alive ?till everything is flashed. I don?t know how it works with just a nic, I wouldn?t use a nic for iScsi root access. _______________________________________________ K12Linux-devel-list mailing list K12Linux-devel-list at redhat.com https://www.redhat.com/mailman/listinfo/k12linux-devel-list -------------- next part -------------- An HTML attachment was scrubbed...

Although I had to muck around with the lts.con file for 2 hours to find the right combination :(, I got it working :). It turns out I had to force SWCursor to be on, not HWCursor to off... odd, I know. Oh, and the line needs to be escaped by backslashes not single quotes ;) So basically I ended up adding this to my lts.conf file: X_DEVICE_OPTION_01 = "\"SWCursor\" \"1\"" Now I am in 1680x1050 DVI heaven ;) For what it is worth, if anyone has a wide screen LCD with DVI and wants to optimize that, here are the lines I had to add to my lts.conf: X_OPTION_01 = "\"ForcePanel\" "\"True\"" X_MODE_0 = "1680x1050" Luckily, I was anticipating having troubles with the DVI and resolution since my LTSP 4.2 has the same issues. At any rate, thanks to everyone for your helping suggestions. Now if I can just get my sound working, I would be one happy camper :D. Regards, Andrew P.S. Is there anyway to search the mailing list archives? I will probably have more questions, but I don't want to repeat what is already out there.

Right now, I'm attempting to put up a guide to doing a Single NIC (aka "Mixed network") install. I haven't done my own single NIC install yet, though I will be trying one next week, so it's only a vague outline of things that need to be changed. Plus I'm never going to be able to cover all the possible permutations that you can do using the single NIC mixed into an existing network. My thinking is that, as this page grows, we will create separate pages for each advanced networking topic and link to them. Authentication to LDAP or Active Directory integration, NFS mounting /home from another server, NBD Root filesystems, Setup on a mixed network (aka Single NIC setup), etc. Right now I'm just putting them all on this page for the moment. If you have anything to contribute (or pointers to existing guides that are still good) for Fedora 9 and 10. In short, I'm looking for anyone who wants to add to an article or write one up.

More generally I want to know what topics people feel are missing from the Wiki documentation. We can create a list of missing topics, prioritize it, then create a TODO page to make it easy for volunteers to know what they can work on.
