I setup Ubuntu 10.10 (edubuntu) along with ltsp. I have an environment with a windows network (192.168.1.0) and a subnet (192.168.0.0) that the new terminal server is on. Everything seemed to be connecting properly, but when I attempted to boot the first client, I get the error message: "Cannot connect to NBD server".
View 1 RepliesI have configured server ubuntu 11.04. Everything works fine, but there is a need for some clients to connect local hard drive. What should I do? How and what modules are added to the ltsp-image? How to register in the fstab on the client? Maybe I'm going the wrong way?
View 1 Replies View RelatedI 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'm using Ubuntu 10.04, How can I install LINUX TERMINAL SEVER PROJECT to ubuntu & I want to know, Can I connect to Internet via 3g modem with LTSP & How can I share internet with thin client machines.
View 1 Replies View RelatedVersion 9.10 had been installed via the alternate CD as the LTSP Server Edition. In place upgrade to 10.4 completed normally via Update Manager. However, LTSP terminal boot now fails with error "Forbidden directory" and "Access Violation". The following was found . Ubuntu 10.4 uses tftp-hpa. Either this is a change from Ubuntu 9.10 or the default behaviour of tftp-hpa has changed. So now, the filename argument given in /etc/ltsp/dhcpd.conf must include the full pathname. The previous requirement was to exclude the chroot path. If this is documented somewhere, I missed it. And after modifying /etc/ltsp/dhcpd.conf, do not forget to restart the dhcp daemon $ sudo /etc/init.d/dhcp3-server restart
View 7 Replies View RelatedI got myself a HP t5000 series Thin client to use on my LTSP 10.04. I changed the Bios to boot PxE. When i restart the thin client it asks for a DHCP and finds the LTSP-DHCP server all is good. Its got a IP address ok, the boot process starts. ok I get the Splash screen for Ubuntu. and all is going well. ok I no get a login screen. All is going very well. (As normal with Ubuntu). I can login all is good the login starts and i get the start up sound.But then where normally one would expect to get a desktop, one gets a login screen. Not knowing the full boot procses im not sure where to start to look. Knowing linux there would be a log file somewhere, that stores the LTSP Terminal Bootup/login process and would tell me where its stopping/failing.
The good news is that when i boot a fat client in all works ok and i an able to get in with a desktop.
I want to been able to connect remotely via RDP protocol with a client (for example from work to house) and I found that I can use [URL... What packages I need to install, and how I configure it? I connect my laptop via wireless throught eth2.

Now I've upgrade the server to Karmic Koala (9.10) and it just stopped working.
1) The clients have PXE NICs
2) They get the proper IPs from the DHCP server and respond appropriately to changes in the DHCP configuration files.
3) DHCP server also points the clients to
filename=/ltsp/i386/pxelinux.0
4) When the clients try to download the pxelinux.0 over tftp they just timeout
5) /etc/inetd.conf has an entry like
tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot
6) The file /var/lib/tftpboot/ltsp/i386/pxelinux.0 exists on the server
I'm lost at all these configuration files and protocols.

I am currently running LTSP on Ubuntu 10.04. It is a dual gig nic setup with 16GB of ram and dual AMD quad core 2.4s. I installed all the latest updates as well as likewise-open so we can use AD authentication. When testing the configuration in the lab, I boot 32 clients that successfully reach the login screen. Here comes the interesting part, I can log in, using all unique AD accounts, up to 22 clients. When I attempt to log in to the 23rd client LTSP hangs. If I restart a client it will retrieve an IP address, but TFTP will eventually time out. All of the clients are connected to a Gigabit switch along with the server so network speeds are not an issue. When I run system monitor it only shows 3.6GB of memory in use and the processors are all under 10% utilization. I have beating my head against this issue for 2 days .
View 1 Replies View RelatedI've successfully built my server, and any fat or thin client that I connect to it boots wonderfully, with great response. I've gone through this exercise because we need a more efficient way of testing computers before delivery to our customers. So, I'm trying to run Passmark's BurnInTest. I've run it before with previous versions (9.something, I think) and it worked well, but I needed to build a new server so we can test more computers concurrently, so I figured I'd get the latest release.
My problem occurs when I try to run BurnInTest - it must have root access to test the local USB, parallel, and serial ports, and the optical drive. For the previous iteration I used a script that dropped into a local xterm session, su'd to a root session, and called the BiT GUI. In this attempt, the same scripts, even when I single-step them manually, results in 'authentication failure' when the su is attempted.
I have enabled the root account and created a password for it in the chroot /opt/ltsp/i386, and rebuilt the image, multiple times, no joy. Using ctrl-alt-F1 I can log in as root, and using dmesg I can see the USB device register when I connect it, so as far as I can tell the root account is alive and well, just not available in a local xterm session for some reason.
I have been at this for what seems like forever but i am getting somewhere after many errors i got dhcp3 reading the file and everything is almost there but now i got an error i cannot figure out.first my config file

In internets there are lot of successless stories installing ltsp on ubuntu 10.04. Most problems are in ndb, init scripts and somewhere else, which are hardly debuggable. It seems like ubuntu 10.04 has ltsp packages completely broken and abandoned. Have someone succeeded to install ltsp on 10.04 without hard brainfucking? Maybe it's better to install ltsp from scratch, or choose another distribution?

View 1 Replies View RelatedI want to install Ubuntu LTSP on top of an already existing system. However, I want to use a different DHCP and TFTP server. Do I simply just install 'ltsp-server-standalone' with apt and run 'sudo ltsp-build-client', stop the DHCP and TFTP server and stop them from starting automatically? Would I then just copy over the pxelinux.cfg/default file from /var/lib/tftpboot along with the initrd.img and vmlinuz images to the TFTP server?
Edit: Do I need to actually copy the whole /var/lib/tftpboot/ltsp directory over to the TFTP server?
I've been asked to investigate the possibility of using LTSP in our school to provide a more "real world" programming environment to our students. We have a Windows 2003 Server domain and no plans to change it.I've set up the LTSP server, joined the domain and everything seems to be working fine, I can login to the LTSP server with a student account.
The next thing I want to achieve is give the students access to their "My Documents" folder on the Windows 2003 server. Is it possible to have a student log on to the terminal server (who has never logged in before) and have it automatically mount their share on the windows server?

When i try to connect to my server via port 443 i get a connection refused error. However when i try to connect via port 22 it connects. Since that didn't work, i tried restarting the entire server.To restate, i changed the config file and restarted ssh then the computer, however the port didn't change.Ohh and yes my router is set to port forwarding on port 443, though it doesn't matter since I'm inside the network.
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.

I've just set up an LTSP server, with all its clients on a separate subnet to my main network - the main network is 192.168.1.x, and the LTSP clients are all 192.168.2.x. My LTSP server has 2 NICs, one on each network, and is merrily forwarding normal IP traffic from the clients to the rest of the network. I have a client/server application that has a server on one machine, and clients locate and attach to it using multicast protocols. The server is on the main network, and any other machines on the network can locate and talk to the server quite happily. The LTSP clients, however, cannot - I assume because the multicast communications aren't being forwarded by the LTSP server. How I can get this working?

I have an Edubuntu server with two nics joined to the primary windows domain and I can log on with domain credentials and everything is AOK. I used LikewiseOpen 6 to join the server to the primary domain. So, on my Edubuntu server eth1 is connected to the primary domain and has a static IP. eth2 also has a static IP and is the DHCP for the thin client subnet, connected to a switch. IP forwarding is enabled.
DOMAIN - eth1 - Edubuntu Server - eth2 (SUBNET) - switch - clients
So far, so good: I can log on the thin clients with one of the local accounts specified on the Edubuntu server and with that account I can surf the net and, if I supply domain credentials, browse the primary domain. Problem I have is:
I can't work out how to log on to the primary domain with a Active Directory account directly from a thin client. If I try DOMAINuser to log on, after giving the password, the password screen refreshes and 'domainuser@11.*.21.*'s password' appears under the blank password box. The IP in that message is the IP for the subnet and not the primary domain. I feel like I'm miss-understanding some basic simple step but I just can't figure it out.
I have openssh installed and it works great right out of the box. However, I don't want people accessing everything on my machine. My machine is behind NAT and ufw firewall. I have configured both so that port 22 is open. I've added the new users I want to have limited access and assigned them to group "sambashare" (just because its convenient.)
When the bottom bit of my config file "/etc/ssh/sshd_config" is set as shown below, everything works great:
Quote:
#Subsystem sftp /usr/lib/openssh/sftp-server
Subsystem sftp internal-sftp
UsePAM yes
Match Group sambashare
[code]...
Whenever I make the change to enable "ChrootDirectory" so that it limits the users access, I simply remove the # and it looks like this:
Quote:
#Subsystem sftp /usr/lib/openssh/sftp-server
Subsystem sftp internal-sftp
UsePAM yes

However, thats when I start running into problems. When I try logging in with Filezilla; I am not able to connect and this is the response I get from Filezilla:

My school are cutting costs.I suggested they go open source.They said if I could find out how then they would consider it.Basically they want a mixture of windows and ubuntu clients.What I would like to no is how a ubuntu machine can connect to a server (SAMBA I think) so that it can access our home folder like the windows machines do.
