Are they any programms in thr ports which allow a similar set-up using FreeBSD. I know you can do this with X but would need a tutorial to help me through it. I think the common solution today is diskless clients where the server is merely a fileserver and the applications actually run on the client. I do not know which scales better - the diskless may cause more network traffic as applications are read but do not continuously communicate with the server. With diskless you need less processing power on the server, but the total processing power may be higher with less utilization. You can build diskless and silent clients with Mini-ITX boards from VIA at a reasonable price. The advantage is that you will have everything in common i386/FreeBSD working environment.

I have forgotten the details, but basically you create a swap file of the required size like this # dd if=/dev/zero of=/path/to/swapfile bs=1k count=64k (to get 64MB) and mount that.

Remember that the main cost is maintenance, not the hardware. I think that the way to do it is not dumb terminals in the old sense, but rather sharing disks, while each terminal runs processes separately and have lot's of RAM - 1GB. 100Mbps network should be ok, just make sure it's switched (which all are nowadays), it's only loading the applications that is slow - once up, there is not much on the network when applications run on the client and there is plenty of RAM. I would think that more RAM gives better user experience than faster network. Some recommends booting off a flashrom, but the disadvantage is upgrading the base system has to be done on each client. For example: Buy some mini-itx MB's with 1GB ram. For desktop use, processor is not important, RAM is. So get some fanless MB's. I have found that VIA MB's are easy to work with, support pxeboot, see this site: www.mini-itx.com. Then you need one file server to allow NFS mount of everything. I sat down and wrote about it, but I never got through to have a working diskless with all the bells and whistles, see this article: www.daemonsecurity.com/pub/pxeboot/ Other sources are the pxe and diskless articles in www.freebsd.org/doc/en_US.ISO8859-1/articles/ Cheers, Erik -- Ph: +34.666334818 web: http://www.locolomo.org X.509 Certificate: http://www.locolomo.org/crt/8D03551FFCE04F0C.crt Key ID: 69:79:B8:2C:E3:8F:E7:BE:5D:C3:C3:B1:74:62:B8:3F:9F:1F:69:B9 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Re: Thin terminals for FreeBSD
> - Is there a more cost-effective solution? (Something that I did not > think of) We used to build (well my colleague did that) X terminals based on a thin configuration of freeBSD (must have been version 2 at that time) that we ran on diskless computers booting from floppy. At that time we ran it on pentium 100 MHz, with something between 16 and 32 MB RAM, over a 10 MB shared Ethernet. All applications ran on the cental server, and X terminals were just that: display devices. It was a bit slow, you could not look at a video, but otherwise it worked. Of course you need more horse power on the server, but if you have a set of old PC with similar video adapters, that's an easy solution to deploy once one machine is up.

Just one addition: instead of running firefox and thunderbird locally on the diskless nodes, you can also run them remotely on a box with locally mounted filesystems (using DISPLAY, which is set automatically when you use 'ssh -Y'); the thr_*() hangs disappear then. They must be NFS-related somehow. Oh, if you run X apps remotely, you don't need more than 256 MB RAM on the thin clients; perhaps even less, but you'll have to test this yourself. -cpghost. -- Cordula's Web. http://www.cordula.ws/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Re: Thin terminals for FreeBSD
In these days of commodity PC pricing running X-terminals isn't really cost effective. You'd be better off buying 10 - 20 identical PC's loading and configuring one, and then clone the drive for the rest. Using X-terminals will likely cost more per unit, and produce more load on the server, the only positive to X-terminals is in configuration and maintenance. That's my 2 cents anyway. -Derek At 02:19 PM 8/7/2006, =?ISO-8859-2?Q?Nagy_L=E1szl=F3?= wrote: Hello, I need to setup an environment where some users (10 to 20 employees) will use terminals to run programs.
