[Ltsp-discuss] Slow app launch time (inkscape worst)

2009-12-14 Thread Jim Kusznir
Hi all: I've got a fairly successful ltsp deployment here based on ubuntu 9.04. The last complaint I currently have from my users is the excessive launch time of some applications. The most notable is inkscape, which takes at least 2 minutes to show up. Other apps take a bit longer than I'd

[Ltsp-discuss] How to set up NX from thin clients?

2009-10-30 Thread Jim Kusznir
Hi all: I'm setting up a thin client system here in our research lab at WSU. We have one very important application that was home written, but presently has a little bug that results in excessive X redraws...To the point where running the system reasonably REQUIRES direct X and at least 30MB/s

Re: [Ltsp-discuss] LTSP5 on CentOS 5.3

2009-10-16 Thread Jim Kusznir
Hi all: I'd like to thank those who are working on ltsp5 and CentOS/RHEL 5 integration. Right now, the biggest single hinderence to LTSP5 usage is CentOS deployment, and as such, we are considering rolling out a new LTSP 4.2 deployment (which does work with CentOS). I think that given LTSP's

[Ltsp-discuss] NFS problems on Netgear switch

2008-02-11 Thread Jim Kusznir
Hi all: I have a very strange problem. I have a working LTSP 4.2 setup. Our network infrastructure is built around HP Procurve switches. We have our primary LTSP server in our machine room, and thin clients in two buildings throughout the building. All this works fine. Then, one of our labs

Re: [Ltsp-discuss] Howto use LTSP as HPC cluster ?

2007-10-26 Thread Jim Kusznir
Given all the problems you're going to have getting all the libraries and software you're going to run running in an LTSP enviornment, I'd suggest you abandon LTSP for HPC purposes. You're better off running something designed for HPC use, such as ROCKS cluster. There's even a config package

Re: [Ltsp-discuss] Load balancing, just a thought

2007-10-11 Thread Jim Kusznir
Load-balancing seems to come up a lot on this list, and in my own configuration. Its also rather difficult to do at an ideal level, as the load is session-based. By that, I mean when a user logs in, s/he does so on a specific server, and for the duration of that login, the session cannot be

[Ltsp-discuss] NeoWare Eon PCI Graphics

Hi all: I just bought a lot of 30 Neoware Eon's from a computer referbishing company with the intention of following Roy's advice in a past thread about dropping in a PCI graphics card into these clients. Unfortunately, I'm running into difficulty. I have 30 Eon 2000E's (it was a all-or-nothing

Re: [Ltsp-discuss] parallel AC and CAT5 cables = impossible?

2007-06-29 Thread Jim Kusznir
From your initial post, it sounds like the AC and CAT5 will each be in their own conduit (i.e., the AC will NOT be running in the SAME conduit as the cat-5). If this is the case, I suspect you'll be fine with 100Mbps..Don't know about Gig, though. If you're concerned, running shielded cable (and

I've got a Devon IT $139 thin client (400Mhz fanless model); its great. No problems, it just worked with LTSP. We're probably going to use that for all our single-headed thin clients (still looking for a cost-effective dual-head solution). Also would like to find a cost-effective accelerated

Hi all: So, my boss just went and sold to his bosses the idea of using LTSP in our Electrical Engineering coding lab. This is a good thing, except a firm requirement for all these systems is that the users must be able to plug in their EE boards (Xilinx/Digilent FPGAs) into the systems USB port

Hi All: We recently discovered JackPC (http://www.chippc.com/products/jackpc/). The product looks really cool; its very small (fits into a standard single-gang network box), uses little power (powered by PoE; uses only 5W), and appears to be reasonably powerful. In addition, its in the nomral
