CentOS 5 Server :: Install / Configure A LTSP In 5.3
Apr 15, 2009
I'm trying to install/configure a LTSP in CentOS 5.3
I have dhcp, nfs and tftp installed, but i can't install/configure XDMCP. I was reading some manuals and "hows to" and all says that, to configure XDMCP, i have to change de atribute "Enable = true" in the file "/etc/X11/gdm/gdm.conf", but i don't have this rute, only "/etc/X11/", gdm folder doesnt' appear :S also... why i can configure XDMCP?
When i run "ltspcfg", he says:
[root@localhost ~]# ltspcfg
ltspcfg - Version 0.11
Checking Runlevel....: 5
Checking Ethernet Interfaces

I am trying to install and configure LTSP on a server for a HP thin client to boot off. The version of Ubuntu that I am using is 11.04 x86 and it is a fresh install on a dual core system with 2GB RAM. I followed a guide which comprised of these commands.
sudo apt-get install ltsp-server-standalone openssh-server sudo ltsp-build-client or if your on a 64-bit system with 32-bit machines do sudo ltsp-build-client arch i386 for editing the servers IP values use /etc/ltsp/dhcpd.conf after that you need to restart DHCP server sudo /etc/init.d/dhcp3-server restart
and update sshkeys -sudo ltsp-update-sshkeys and if you updated dhcpd.conf then you need to update you image also by typing in terminal ltsp-update-image
Everything seemed to install as it should but when I try to boot from the thin client it just times out and says no DHCP or proxy invites received. I turned DHCP off on the router and even tried another router, but I still get nothing. I am at a bit of a loose end and I hope someone on here can point me in the right direction of where I am going wrong.

I installed in Virtualbox many times and the clients would not connect. The config of the dhcpd.conf was the problem.Now, Everywhere I kept reading it said I had to turn off my hardware routers dhcp. Thats wrong, I have it working with it on and with one network card. Heres the nuts and bolts. Dlink 4100 hardware router assigning address block 192.168.2.200-250 to pcs on the lan. Router is set to reserve and IP for the ltps server nic so it gets the same IP assigned every time from the hardware router. No need to force linux to an ip when it can be set in the router. Then installed LTSP from alt-cd. Once done, dhcp wont run because it conflicts with the hardware dhcp. Found out by trying to restart it and it said stop - Fail when it tried to stop it.
sudo /etc/init.d/dhcp3-server restart
So edit /etc/ltsp/dhcpd.conf.
sudo gedit /etc/ltsp/dhcpd.conf
Mine attached below: The subnet, as long as the 1st three numbers match the rest of lan setup it will work.(192.168.2.0), rest of my lan is 192.168.2.x. Now notice the range is a different block than the hardware dhcp server uses. So all thin clients that connect will be assigned something 192.168.2.100-150 and all hardware connected pcs will be assigned 192.168.2.200-250 from the hardware router. So no conflicts. Then for the domain name server, set it to the hardware router ip. My hardware router is 192.168.2.2. Set option router to the same as hardware router of 192.168.2.2 Nothing in my dhcpd.conf file is pointing to the ltsp dhcp server. Nothing else had to be edited in the dhcpd.conf Next hurdle I had, after any change of the dhcpd.conf, ip's might have changed and you have to reconfig the ssh and the image. run these 2 commands.
sudo ltsp-update-sshkeys
then
sudo ltsp-upadte-image
then
sudo /etc/init.d/dhcp3-server restart
Then thin clients/lan boot pcs all can connect after that.
I have since installed again at work in virtual box, booted from another vbox client and booted from a separate lan pc. Then installed again at home on AMD 3200 Athlon, 1 gig mem. Booted from my main pc PhenomX4, no problems. Pc's must have lan boot available in the bios or net boot available on the network card(most consumer add on cards do not). But most motherboard lan connection do.

How do I know what sound system my Centos 5.5 install is using and how would I configure which soundcard output to use? I want to use the digital coax output from my M-Audio PCI soundcard, which appears to be detected and loaded. When I launch MPD, it autodetects an alsa sound system, but programs like alsamixer don't exist and I can't hear any sound out of the digital coax output. I haven't checked the 3.5mm stereo out yet.A little confused as to which documentation to be looking at at this point.

I have one server at home, connected through a router that gives me a static IP:192.168.1.2 - My PC192.168.1.3 - CentOS serverI enabled the port 80 into router forwarding system and I can connect properly to CentOS server, using the IP my internet provider gives me. My router automatically forwards a changed IP to my dyndns.com account so I can also access the server through a domain name (I pay to have it linked to one of my domains).My next step is to configure the mail server (dovecot) , so I can send emails from my local server(192.168.1.3).I was wondering if anyone has any tutorial links or tips to have the mail server configured through a home internet provider + home router.

i'm teacher and have been assigned to take care a small computer lab in my school.in my computer lab there is a centos box with 2 network cards, switches and computers.at this moment all the computer can access the internet directly without connected to the router or server..(bypassing the centos box).so now i would like to make my life more " difficult" where i want all the computers access internet through my centos box so that i could have a better internet usage management.
I've been reading some forum and even centos document regarding establish networking but it seem difficult for me to understand all the terms and jargon overnight.I also have been try to configure the 2 nic using the "trial and errors" approach but no luck..i'm really hoping that someone could guide me so that i could configure the 2 nic correctly hence my centosbox could be more beneficial..below is the scheme how my network will be..internet------>modem--------->centosbox--------->switches------->computers(eth0)(eth1

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

Currently have a problem with my LTSP server when using a gigabit switch with a megabit thin client.I am using K12LTSP with Fedora 9.The thin clients get most of the way through booting up then I get error messages saying:nfs: server 172.31.6.1 not responding, still trying.I don't get this problem if I use a 100 meg switch though.I have found several forum posts on the internet which all seem to point to the following webpage with a solution:However, when I make the recommended changes It doesnt make a difference.Below is an example of the default file located at /var/lib/tftpboot/ltsp/i386/pxelinux.cfg with its default settings:
Code:
