Hello, I found a bug in ipconfig and I'm sending a proposed patch for it. I've only seen it happen in 2 dhcp-server environments. Scenario: ipconfig sends a DHCP_DISCOVER, server A answers with a DHCP_OFFER, server B answers with a DHCP_OFFER, ipconfig sends a DHCP_REQUEST for server A, ipconfig accepts the DHCP_OFFER from server B instead of DHCP_ACK from server A. <== BUG The reason

Hi. I have a machine with a local DHCP server and a couple of virtual networks and I've configured the server for each virtual interface, so that I would be able to install VMs on the corresponding subnets using PXE. The problem is that the two DHCP servers (my local server and dnsmasq) are conflicting with each other causing the boot process to either fails or takes ages untill a VM can

Hey folks! I want to add a CentOS 5.2 domU to an existing server (Fedora 8) which was setup by another company. The Dom0 does not provide any other services but a BIND-DHCP-server (they deleted dnsmasq and installed bind). Don''t ask my why they did that. My new DomU is connected to eth0, which is a bridge. BIND also listens on eth0 to serve other machines. I start the install of centos

Hi - On my CentOS 4 cobbler server i am having some odd dhcp issues. There is only 1 dhcp server on the network and the cobbler box manages the dhcp. When i kick off the PXE install during the PXE phase things seem OK then when anaconda tried to get an IP sometimes things work out fine and other times it sits waiting for hostname/domainname. From the logs you can see that the mac requesting

Dear folks, We are installing a large diskless cluster using CentOS 5.1. The hardware is pretty new - Supermicro X7DWT boards with Harpertown CPUs. Unfortunately we have some PXE-related problems described by the following scenario: 1) Set up DHCP, TFTP and NFS on a server, prepare PXE kernel and initrd - fine. 2) Start up the node using PXE for the first time - fine. 3) Reboot the node - PXE

Hi, I'm trying to configure PXE syslinux to boot a diskless client but the client can't find the PXE boot image. I've configured the DHCP server as follows: ---------------------------- # cat /etc/dhcp3/dhcpd.conf option domain-name "cluster.net"; option domain-name-servers 10.0.0.1; default-lease-time 6048; max-lease-time 604800; log-facility local7; subnet 10.0.0.0

...here is the problem, ipconfig accepts any offered addresses, even those that don't have the filename option. So the clients may get their ip from the wrong dhcp server (e.g. the adsl router) and fail to boot. What I'm asking for is a command line option, that forces ipconfig to ignore all DHCPOFFERs that do not have a filename option, so that it only accepts ip addresses from ltsp servers. Kind regards, Alkis Georgopoulos IP-Config: eth0 complete (from 128.131.48.127): address: 128.131.48.177 broadcast: 128.131.48.255 netmask: 255.255.255.0 gateway: 128.131.48.1 dns0 : 128.130....

Dear Centos-Virt: This is actually a second request for help on the same issue. I finally got to try what several months ago was replayed to me and no joy was to be had.
