similar to: 2 DHCP servers - different VLAN's

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

Hello to all. I'm trying to implement a simple register allocator using graph colouring (I know, everyone has already done that :-)) and I'm also using LLVM 3.4 from master branch. The algorithm I'm using is based on the one described on the "Modern Compiler Implementation in C". My implementation is totally experimental and doesn't aim to be fast, eficient or even

Package: logcheck-database Version: 1.2.23 Severity: minor Hi, a couple of minor corrections to the dhcp rule sets: First of all, the hostname matching parts need to include the "._-" signs (maybe . is not needed but it might be). Then when using failover, log lines of type DHCPDISCOVER and DHCPREQUEST may be entailed by the string ": load balance to peer <somestring>".

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

Hello all, I have a CentOS box that has a NIC (eth0) on which I defined 4 VLAN's (counting the NIC itself): eth0, eth0.1, eth0.2 and eht0.3. Initially the Cisco switch was not partitioned into VLAN's which means that the only VLAN running on it was the default one (VLAN 1). I have then played with VLAN's a bit on the switch and at this point have two: VLAN 1 (which is default and can

Silvertip257, when you did this CentOS 6/KVM/bonding/bridging, did you ever get all the parts playing together correctlhy? I'm facing a setup with only two NIC's, and need for multiple trunked VLAN access, and bonded pairs, and KVM based bridges to get the VM's with exposed IP addresses. I can get basically any 2 out of the 3 server network components working, binding, VLAN's, or

I want to know, is it possible for an external network added in xenserver, to be part of multiple Vlans? If so, what are the commands to do the same.? -- Regards, Manoj R _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hello all: According to rfc 2131, page 9: "ciaddr Client IP address; only filled in if client is in BOUND, RENEW or REBINDING state and can respond to ARP requests. " Is it ideal to change "boot.ciaddr = dev-> ip_addr" to "boot.ciaddr = INADDR_ANY" in dhcp_send() function? I've used a TP-LINK TL-R402M router and it

Perhaps my deffinition of multi-threaded is skewed/wrong... I've got asterisk HEAD running on a 4 proc machine. I'm using top as my guide (and yes I know top sucks, but what else do I use?). I just watched asterisk hit 63% cpu usage for about 5 seconds. There were 5/5 G729 licenses in use and 6 calls up during those 5 seconds. CPU #2 had an idle of 39% and CPU #3 had 98%. CPU's

Hello, After asking around in #centos and other linux related IRC channels, here I am, bugging all of you. brace for the long post. (tldr: dhclient loses virtual interface ips) I set up a system to deploy statically assigned IPs to physical and virtual interfaces to a number of (virtual) machines. I have a DHCPD with an entry for each virtual ip in the form of host eth0-1.virt1.test.it {

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

Hello everyone. What's better for Asterisk: have 2 distinct 100Mb network cards in the system, one on the "internet" and one on the "local net" OR have one 1000Mb network card with 2 separate VLAN's set up? It's a difficult decision because 2 cards are using 2 IRQ's etc but a single 1000Mb card might generate more PCI interrupts and get me into different

Hi, I have a firewall running IPTABLES. I have tried to route sip traffic from my WAN(eth3) interface to a VLAN(eth2.2) interface, however the data will not route to the VLAN it keeps routing to the default interface(eth2). Does anyone have an idea as to what I need to look for? Regards Jennifer Botten ETECH Tel: +2787 150 5285 Fax: 086 638 2412 Mobile: +27 82

Hello all, I''m using shorewall on a linux machine that has two interfaces, eth0 being connected on the internal network (10.10.10.0/24) and eth1 being connected to the external network. On eth0 the IP is statically configured to 10.10.10.254 and there is a dhcp server running for the machines in the private network. On eth1, the IP is dynamically assigned by my ISP modem that acts as

Hey CentOS list! I've got an oddity with a diskless client setup that I suspect is the result of the initrd.img I'm using, or some parameter I'm unaware -- or I need to build my own initrd image (and could use some assistance on what has to be done in that department) Testbed is defined as: VM A: ip: 192.168.250.10 with dhcp server, tftp server, nfs server VM B: pxeboot VM,

I have a question about bridges, vlans and switches. We had been using a bridge to provide filtering between our student labs and the main network. All the filtering does is check that a known IP matches a known MAC address, this stops students plugging in laptops and stealing an IP address. (And yes, we know about the MAC spoofing issues too) The connection was nice and simple,

Given a choice, and a green-field site, would you a) Have a separate network (switches etc) for your data and phone b) Use the same network, but use VLAN's ?? What are the pro's and con's of each ? TIA Julian

Thank you everyone. OK, the mystery deepens, I guess. The machine does need to support several VLAN's, it is currently on a trunkport (8021q encapsulated), it made it into the ARP table - which I specifically tested for by physically unplugging the table, clearing the ARP table and plugging it back in. The ARP table currently looks like this: hq#show arp Protocol Address Age (min)
