IMHO James Kinney is the person that really knows the channel bonding setup with K12LTSP CentOS (Sorry for putting JK on the spot). Google for chanel bonding. I'd pick channel bonding as the way to go. But ... as for a second network, that should be possible by adding another network. Below is how my dhcpd-k12ltsp.conf file is set up on a system I have. It handles dhcp on the main network (10.) for the Windows systems, and also is still the dhcp server for the thin clients on 192.168.0.x network. I suppose you could change my Desktop section (10.) to be a different 192.168.1.x network by just copying the workstation section and changing the IP addresses, then add the correct entries in /etc/hosts and have it also work. Then, again, that might break everything. I do know that this setup works very well for me and I am using samba as a PDC (10.179.2.9) with this DHCP setup. dhcpd-k12ltsp with two networks: default-lease-time 86400; max-lease-time 86400; ddns-update-style none; allow booting; allow bootp; option option-128 code 128 = string; option option-129 code 129 = text; option option-221 code 221 = text; shared-network DESKTOPS { option subnet-mask 255.255.0.0; option broadcast-address 10.179.0.255; option routers 10.179.1.1; option netbios-name-servers 10.179.2.9; option netbios-node-type 2; option domain-name-servers 10.179.2.6; option domain-name "ncs.k12.de.us"; subnet 10.179.0.0 netmask 255.255.0.0 { range 10.179.3.100 10.179.3.253; #use-host-decl-names on; get-lease-hostnames true; option log-servers 10.179.2.12; } } shared-network WORKSTATIONS { option subnet-mask 255.255.255.0; option broadcast-address 192.168.0.255; option routers 192.168.0.254; option routers 192.168.0.254; option domain-name-servers 192.168.0.254; option domain-name "ltsp"; next-server 192.168.0.254; option root-path "192.168.0.254:/opt/ltsp/i386"; subnet 192.168.0.0 netmask 255.255.255.0 { range dynamic-bootp 192.168.0.005 192.168.0.125; #use-host-decl-names on; get-lease-hostnames true; option log-servers 192.168.0.254; # trick from Peter Rundle # newer Macs if substring (option vendor-class-identifier, 0, 9) = "AAPLBSDPC" { filename "yaboot"; option vendor-class-identifier "AAPLBSDPC"; } # really old iMacs elsif substring (option option-221, 0, 5) = "Apple" { filename "yaboot"; option vendor-class-identifier "AAPLBSDPC"; } # Intel PXE elsif substring (option vendor-class-identifier, 0, 9) = "PXEClient" { # NOTE: kernels are specified in /tftpboot/lts/pxe/pxelinux.cfg/ filename "/lts/pxe/pxelinux.0"; } # default to an i386 BOOTP image else { filename "/lts/vmlinuz.ltsp"; } if substring (option vendor-class-identifier, 20, 3) = "ppc" { option root-path "192.168.0.254:/opt/ltsp/ppc"; } else { option root-path "192.168.0.254:/opt/ltsp/i386"; } } } # example configurations for specifying specific kernels to specific clients group { use-host-decl-names on; option log-servers 192.168.0.254; host ws001 { hardware ethernet 00:40:63:cb:08:88; fixed-address 192.168.0.1; filename "/lts/pxe/pxelinux.0"; } } On Fri, Feb 5, 2010 at 10:38 AM, James Huffman wrote: > I am trying to install another network card to handle terminal traffic > better.

Message-ID: Hello, I hope you are all doing very well. For several years now I've been using a custom-built server for our K12LTSP (now K12Linux) setup. It's been supporting around 15 clients and has been chugging along faithfully. It does not have a very high load on it but when you do push it, it does show some weakness. The specifics for this machine are: Pentium 4 2.4 Ghz with Hyperthreading ASUS P4P800 Motherboard 3 GB RAM (max 4) 2 x 37 GB SCSI drives in RAID 1 configuration 2 x Intel Gigabit NIC Recently I received a Proliant ML370 with the following specifications: Pentium III - 1 Ghz (Has an empty slot for a second processor) Max 4 GB RAM 2 x 18 GB hot-swappable SCSI drives (can hold up to 6 drives) 1 onboard 10/100 NIC (Detailed specs here http://h18000.www1.hp.com/products/quickspecs/10493_div/10493_div.html) I guess the only thing that makes me consider the Proliant as a possible LTSP server is the fact it can handle 2 processors and so should be able to scale better. I'd like to start pushing that the school uses the computers more, but I'm worried that the current server can't handle such an increased load and will cause problems. Am I correct in my thinking or is the current one better than the Proliant, or some other option?

In-Reply-To: References: Message-ID: IMHO, I don't think you're going to gain much if anything going from a P4 down to a dual P3. I would highly recommend searching for a used server, Poweredge or Proliant. You can get something pretty powerful for not a lot, particularly when you consider that a new LTSP server essentially means a new lab. My first LTSP server was a quad p3 800 MHz PowerEdge I had purchased myself for under $500 off EBay, and I ran 20 clients off of ok. When that died, my district let me purchase a quad p4 2Ghz that was only $1200 and it was like getting 20 new high powered machines. I think if you hunt around, you can find a server class machine with MEGA power for well under $1000. If you're doing this for a school, I bet someone in the community has a server they've recently decommissioned that would be better than what you're using now. I do believe more processors can do LTSP better.

I'd try to configure the proliant to share out home directories with the P4 (and potentially others) as the login server. I'm not sure if K12Linux handles that the same way that k12ltsp would, but lots of disks in a suitable RAID configuration is the important part for file service and a fast CPU is needed where the apps run, and these don't need to be the same machine. -- Les Mikesell lesmikesell at gmail.com From robark at gmail.com Fri Feb 12 18:31:10 2010 From: robark at gmail.com (Robert Arkiletian) Date: Fri, 12 Feb 2010 18:31:10 +0000 Subject: [K12OSN] Which server would you prefer?

I thought people were doing that with k12ltsp for ages and k12linux was supposed to make things more transparent for local apps - which would also need home dir network access. You could use a dedicated subnet with separate NICs for server<->sever NFS access if you need to nail it down. Using multiple servers does mean you are likely to want a central authentication system, though. -- Les Mikesell lesmikesell at gmail.com From brcisna at eazylivin.net Sat Feb 13 02:55:15 2010 From: brcisna at eazylivin.net (Barry Cisna) Date: Fri, 12 Feb 2010 20:55:15 -0600 Subject: [K12OSN] Which server would you prefer? Message-ID: <1266029715.14366.120.camel@localhost.localdomain> Joseph, You didn't mention home folder location? I am assuming you have the users home folders on the existing server you are currently running. Providing you have an open slot in your server rack. A suggestion would be to leave the existing server as it is. Purchase a second cpu for the Proliant server you are talking of. Pop that server in the server rack as well. Point the users home folders on the Proliant server to your 'first' k12ltsp server. You can try and figure the balancing voodoo via dns round robin if you like. I have found there is really no need to do this other than this is the most 'scientific' way of doing it. But, as the clients boot they will go to the 'least busy" server. If you have say 30 machines in a room,within 10-15% of the TC's,will be to one or the other server equally .AKA: almost half to each of the two k12ltsp servers. The big upside to two servers serving x number of clients is regardless of the horsepower any one server has to push out,with two you are simply giving more pipes to x number of TC's. You may as well use ALL of the resources you have available to make you k12ltsp installation as 'robust' as it can possibly be along with the amount of dollars you have available. With this two server setup you will of course have to set up your dhcp parameters for only one of the two servers doing the dhcp,with the second server being "the next server" entry in the k12ltsp-dhcp.conf file. This is how we do it on two subnets-high school/middle school at school for two different buildings.. 2 servers per subnet. 4 servers per building along with AD integration.

I actually have to agree with that if it is at all possible. I've always liked to reuse old stuff but even I have to admit that current equipment is so much faster and cheaper that is rarely worth the power to keep something a few years old running - and that's especially true for 32-bit servers. -- Les Mikesell lesmikesell at gmail.com From joseph.bishay at gmail.com Wed Feb 17 22:05:12 2010 From: joseph.bishay at gmail.com (Joseph Bishay) Date: Wed, 17 Feb 2010 17:05:12 -0500 Subject: [K12OSN] Which server would you prefer?

I've always thought that Linux distributions should just come up running an LDAP server for authentication so that adding your 2nd shared server would be even easier than the 1st instead of having to start over to figure out how to convert both to central authentication.

I used to think that SME server would have been good for a home directory and email server if it had done that (and had NFS by default), but ClearOS may turn out to get it right. -- Les Mikesell lesmikesell at gmail.com From scott at hosef.org Fri Feb 19 20:13:15 2010 From: scott at hosef.org (R.

Peter, the heart behind ClarkConnect and ClearOS, is nothing short of amazing when it comes to documenting and coding. The fact that John joined ClearOS only made it better. The next release provides a NFS gui, so we all have a CentOS based distro that meets all the samba/ldap/nfs/pdc functions needed by many. And, if your administrators feel better about it, you can contract the company for support. However, I'll re-iterate that Debian-Edu continues to define all that is right in an education distribution. This stuff - roaming profiles and ldap - has been integrated for more than 5 years. I'll also emphasize that my DRBL installs use NIS and NFS and can provide roaming profiles to all users, too. The transport is not secure, but, one step at a time. > > -- > Les Mikesell > lesmikesell at gmail.com > > --scott -------------- next part -------------- An HTML attachment was scrubbed...
