Hi, this is a summary of the previous message in a shorter form. The scenario is:
DHCP-Windows-Server <---> Laptop with VirtualBox <---> LTSP CentOS Server 1) Laptop (running MS windows) boots up under the usual LAN environment settings using DHCP. 2) Launch the Oracle VirtualBox from the laptop. 3) Launch CentOS thin client inside the VirtualBox and use the CentOS image downloaded from the LTSP server (LTSP server has only one NIC card). This provides a complete Xwindows/GUI CentOS desktop environment running inside the Oracle VirtualBox. How to configure the VirtualBox on the laptop and the LTSP server so that step (3) is feasible? Any possibilities of the LTSP server interfering with the DHCP-Windows-Server?

Since the LTSP server uses only one physical NIC card, eth0, which has a DHCP IP address of 192.168.10.155, I ventured and set the following in the /etc/ltsp/ltsp-server.conf file: BASE="/opt/ltsp" <=== this is the default setup TFTP_BOOT_DIR="ltsp" <=== this is default LTSP_DEV=eth0 <=== changed from default eth1 to eth0 (NIC card of LTSP server using DHCP) LTSP_DEFAULTIP="192.168.10.155" <=== DHCP IP address of eth0 (netmask is 255.255.255.0) I then ran the command ltsp-build-client --release epel-6-x86_64 --debug --noprogress The installation completed this time. But it still displayed the error during the installation: /usr/share/ltsp/plugins/ltsp-build-client/RHEL/009-mock-chroot: line 83: /opt/ltsp/x86_64/etc/sysconfig/firsboot:No such file or directory (BTW, I also looked at http://www.thefanclub.co.za/how-to/how-create-virtualbox-ubuntu-ltsp-thin-client but this only talks about the Oracle VirtualBox, but not how to install and configure LTSP on the CentOS 6.x side to make it work. Can someone please provide some pointers? I can copy+paste various config files here if needed.) I also looked at https://fedorahosted.org/k12linux/wiki/MixedNetworkSetup Here is the /etc/ltsp/dhcpd.conf file. I imagine I'll need to change various values in it. The LTSP server running CentOS 6.4 has DHCP address 192.168.10.155 and the client is coming from an Oracle VirtualBox on some laptop.

Now we must update the server to boot the thin client image. After that is complete have a look at /var/lib/tftpboot/ltsp/i386/lts.conf and verify everything is setup the way you want.

In the case of the Oracle Virtualbox or some other similar software, the Virtualbox does not have a physical NIC card, and I am not sure if it uses the same NIC card as the Windows 7 laptop NIC card or some other virtual, non-static IP address NIC with a different IP address from the laptop NIC card. Thank you for the pointers. -------------------------------------------- On Tue, 6/25/13, Radek Bursztynowski <ra...@bursztynowski.waw.pl> wrote: Subject: Re: [Ltsp-discuss] Fw: Re: ltsp-build-client failed after 78% completion To: ltsp-discuss@lists.sourceforge.net Date: Tuesday, June 25, 2013, 3:12 AM Good question! I am interested in the answer too. In general in my opinion documentation related to network configuration documentation is not clear. https://fedorahosted.org/k12linux/wiki/NetworkSetup https://fedorahosted.org/k12linux/wiki/MixedNetworkSetup I look for network solution in four cases: A. LTSP server is equipped in one NIC, and (1) physical NIC only, (2) physical NIC configured as a bridge; B. LTSP server i equipped in two NICs (3) with no bridges (one NIC dedicated to Internet connection, the second one destinated to LTSP privet network), (4) with one bridge for Internet connection and the second NIC for LTSP private network. Best regards, Radek --- Hi, I was tasked to use the Oracle Virtualbox running on windows 7 with LTSP on the server side, and download the CentOS from the LTSP server to the Oracle Virtualbox. So there will not be a private hardwired network with just the LTSP server and the thin clients only. And we can assume that the LTSP server has only one network card, which for the test environment is currently a DHCP IP address. In this case what are the appropriate values to use for the two parameters: LTSP_DEV= LTSP_DEFAULT= Thank you! -------------------------------------------- On Fri, 6/21/13, Joshua Trimm <ensla...@enslaver.com> wrote: Subject: Re: [Ltsp-discuss] Fw: Re: ltsp-build-client failed after 78% completion To: ltsp-discuss@lists.sourceforge.net Date: Friday, June 21, 2013, 7:49 AM I recommend these steps: - Clean the yum cache # yum clean all - Remove any half made and non working chroot's along with mock cache. # rm -rf /opt/ltsp/i386 /opt/ltsp/x86_64 /opt/ltsp/mock/epel-* /var/cache/mock/epel-* - Update LTSP server # yum update ltsp-server nbd ltspfs ldm ldminfod - edit /etc/ltsp/ltsp-server.conf and make sure your LTSP_DEV and LTSP_DEFAULTIP are correct # nano /etc/ltsp/ltsp-server.conf - Build the client # ltsp-build-client --debug --noprogress --release epel-6-i386 Follow any additional steps listed in the README.rpminstall Hope everything goes smooth from here on, let me know if you have any other issues. -Joshua ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _____________________________________________________________________ Ltsp-discuss mailing list.
