So these clients are running (just to make sure I understand) nothing but the kernel, minimal libraries, X, and any devices you care to set up? Or are they running even less -- a built-in X? I hate to have to ask, but for me over the decades a "thin client" has been everything from a short-lived custom PC that networked back to a host PC on a network nobody has ever heard of before or since (mid 80's) through a variety of Sun SLC and ELC diskless systems (that ran a fully copy of the OS, albeit booted diskless) through a range of linux boxes booted diskless the hard way, pre-PXE. A 512 MB client damn well ought to be able to just boot and run the entire OS locally and even do it nearly transparently and extremely fast. There has over the years also been forever the question of just where the apps get run -- with X remotely (which even with thick clients and X servers can have mediocre performance on a heavily burdened network or server) or locally (where they occupy what used to be a biggish chunk of memory. The neoware online docs do not help at all with this, and while I'm working my way through the ltsp docs, I haven't been able to figure out yet whether you can boot any terminal image you care to set up (it seems like you could, with ltsp or not) and e.g. mount /usr to become a simple "instant" diskless node. That's why I was asking. Are the terminals set up to be so thin (with LSTP in general) that one pretty much has a bare X server and a desktop, every thing running remote, or do they use their local CPUs for anything like an actual workstation boot into which one can login outside of X? rgb > > James > > ------------------------------------------------------------------------- > Take Surveys.
