We're likely to have 45 thin clients, 25 thick...how many and what speed of server do I need to run fileserver, DHCP, terminal server, and Windows...? [05:20] andrew_: got your LDAP server running? [05:21] I took an LDAP vacation this week and bought a bunch of books to get my grounding in Linux land before taking another swing at it. [05:21] ok [05:21] don't fear, you will conquer LDAP [05:21] The server is running fine...I just haven't succeeded in getting a client to authenticate against it... [05:22] I'm in a position to be buying equipment and I don't want to screw up... [05:22] So I'm looking for 2nd and 3rd opinions... [05:23] ok [05:23] what are you using for your thin clients? [05:23] A mix of donated P4s and whatever we decide to buy, new... [05:24] wow, those are massively powered [05:24] Yes...lucky...should I just turn these into thin client servers? [05:25] We'll have roughly 20 of these... [05:25] but I want to reduce administration on the client side... [05:26] hmm [05:26] how many classrooms? [05:26] four [05:27] three, really, with one computer/study room [05:27] I want 12-15 thin clients in each classroom, with the ability to push in another 20 laptops (thick client) [05:29] I'm constrained to using Dell as the vendor, unless I can show that they don't carry what I need. [05:29] right [05:29] as for teh actual servers, you need to talk to sbalneav or somebody similar [05:30] He recommended 6-8GB of RAM for a single server running 45 clients...but as for processors, I can't tell. [05:31] I'm also a bit shaky on what I need to set up the dual Windows/Linux thin client environment I've seen in some of the case studies... [05:32] you need one or several Windows servers, where the clients use seamless RDP to get an application from them [05:32] He recommended three servers: LTSP (Ram intensive), DNS/Filesever/Webserver (HD intensive), Windows (?) [05:32] that makes sense [05:33] What hardware requirements would the Windows server have? [05:33] have you been a sysadmin much before?' [05:33] No [05:33] the requires of the windows server depend entirely on what you are running [05:33] I suggest you collect a complete set of all applicatiosn you expect to be run [05:33] the Windows ones [05:34] then fire up a thin client and connect to a Windows computer [05:34] monitor the RAM and network output on the windows machine [05:34] If I understand properly, the Xterminal is still running on the LTSP server even when the clients are accessing the Windows server, is this correct? [05:34] the users would still be in an Ubuntu environment [05:35] they would just be accessing a single program off the Windows side [05:35] another way to do it is to do what whiprush does [05:35] he has he machines dual boot [05:35] Windows and LTSP thin client [05:35] That is preferable to me...I think. [05:35] How difficult is that to do? [05:36] not hard [05:36] for that you need a copy of windows on each computer [05:36] and then hack grub to do a network boot, I think [05:36] you need to ask whiprush (Jorge Castro) [05:37] So windows runs locally, not as an application server...? [05:37] yes [05:38] in that case, they are in a full windows environment and you need to deal with each windows install [05:38] the advantage of an application server is that you minimize the number of windows instlals you have [05:38] This would make a true "thin client" machine impossible to use as a dual boot machine. [05:38] yes [05:38] OK...I guess we can handle an emulator window... [05:39] well, with seamless rdp, it is as if the appliation is running locally [05:39] that is what is so brilliant [05:39] In any case, it sounds like the Windows application server doesn't need to be as resource intensive as the LTSP server, is this correct? [05:40] that depends on the application being run [05:40] you also need to consider that graphics-intensive stuff does very badly when run over the network [05:41] So streaming video = bad news...even with a blazing fast, 8MB RAM LTSP server? [05:41] yes, because at that point, the bootleneck is not the server, it is the network itself [05:42] Even with gigabit connection between the server and the switch? [05:42] for that, I would test [05:43] gigabit might do for streaming, but more graphics intensive stuff like games would still choke, I imagine [05:43] that is off the top of my head [05:44] I just need to know whether I need two $6000 servers to run Linux and Windows, or just one $6000 server and a smaller, say $2000 server to host windows apps...? [05:44] like I said, I would figure out exactly which Windows apps you need to run and then take a look at their memory/cpu/network requirements [05:46] Now as for the fileserver, LDAP, DHCP, and webserver...would all of these live on the same machine? [05:47] A third machine, phsically separate from the LTSP and Windows machines? [05:47] yes, if possibly [05:47] possible, rather [05:47] ldap/fileserver can share the same machine [05:48] and also host a website... [05:48] you could repurpose one of yoru p4s for that [05:48] I am very conservative with stuff like that [05:48] I try and separate out the services as much as possible [05:49] makes backup/recovery schemes easier [05:49] I want to give web users access to their LAN files [05:50] Does this necessitate fileserver and webserver sharing the same machine? [05:51] nope [05:52] Here's where LDAP comes in, right? Single authentication point for all services... === kjw75 [n=kevin@198.169.119.200] has joined #edubuntu [05:52] how come when I installed 7.04 I have no educational tools, but they were there in 6.06 and 6.10? === `6og is now known as Birthday_Kaiser [05:57] How do you install seamless rdp?
