Finding DHCP IP of guest system
If I can log in to the guest through the console, I can of course find out what IP DHCP has assigned it. If I configure a static IP I can of course connect to the system there (if it runs services, the firewall allows it, all the usual caveats). Does there happen to be any way to determine from dom0 what IPs are participating in the network and which guests they belong to? (I'm configuring

Trouble getting a DHCP address when booting.
Hi. I spawned a thread last week about the failure of bridged networking and I have gotten a little further. Turns out that I _do_ have network connectivity from inside the domains, but I cannot get the network to come up when I boot. I have to login and start up the network manually. E.g. after installing Debian Sarge according to the debootstrap method outlined in the users manual, I created a

MS-Win7 kvm guest gets dhcp from host bridge
CentOS-6.5 i86_64 qemu-kvm-0.12.1.2-2.415.el6_5.4 MS-Windows v7proSP1 We have installed a MicroSoft Win7 system as a guest and have joined it to our MS AD domain. The system runs and has internet access. However, the IPv4 address it obtains and the gateway it is assigned are both sourced from the virtual machine host system and not from our AD DC DHCP server. To clarify, the virbr0 IP address

Hello listmates, If I have a NIC on my CentOS 6.2 machine two which I want to assign to IP addresses: one acquired via DHCP, the other one fixed - is there a way to do that? How do I do that? Thanks. Boris.

ipconfig:About the length of 'options' field of DHCP packet
Hi, I had the problem that 'ipconfig' as DHCP client in Debian-squeeze could not get DHCP Offer reply from the built-in DHCP server of the cheap route that I have. The name of the router is 'MegaBitGear TE4571E' which I got at contract of ADSL Internet access service in 2009. The router is not too old and can reply to other DHCP clients like ISC-dhclient, WindowsXP and Vista.

UEFI PXE / split config / TFTP attempted to DHCP server, not TFTP server
All, I realize this is not strictly a PXELINUX question. So I hope you'll indulge me; hopefully some of these PXELINUX experts have seen this before. And can tell me what I'm doing wrong. Or confirm my suspicions. I have a test lab server at work. Split config. The network team manages the DHCP servers, points to our TFTP server. Test subnet has 3 DHCP pools. BIOS PXE, UEFI PXE and

grep ip address from KVM DHCP log
> Hi, I plan to use KVM internal network 'default' and grep dhcp log to figure out the IP address that assigned to my VM. I know I can configure static ip but I like to assign ip dynamically to avoid mgmt cost. Does anyone know where the dhcp log is? My KVM host is running Ubuntu Raring (13.04). It does not have file /var/log/daemon.log as some online doc mentioned. Thanks,

KVM and DHCP
CentOS-6.5 We have a KVM guest running MS-WinV7pro. This guest is joined to an Active Directory Domain. That domain provides DHCP to the members. The KVM guest does not obtain its IP from the domain but from the local host's qemu hypervisor instead. Is there anyway to get around this and have the guest MS-Win OS get its DHCP from the same place as the rest of the domain members? -- ***

Server w/ DHCP address incorrectly registers with WINS
I am sneaking Linux and Samba into my client's IT department (with the cooperation of the IT manager) and we have a few issues getting the system talking to the rest of the network. The network we are inserting the system into uses WINS and does not have DNS for local hostname resolution. The system is required to get its IP address via DHCP. The system is running a vanilla install of

How does a linux DHCP machine inform DNS of its name and obtained address
I am using a number of DHCP devices on a network. Working fine with CentOS 5 x86_64. My question is now how do I tell the DNS (after I get my DHCP address) about my devices name and IP address so that others can find me by my machine name? I thought that was an automatic thing - but it appears not. Thanks, Jerry

UEFI PXE / split config / TFTP attempted to DHCP server, not TFTP server
Gene, All good questions. Thanks for taking time to respond. You've given me great leads to follow up w/ DHCP appliance consultant. >filename being file.

DHCP and DomUs: not working
I''m trying to get DHCP working with DomU clients. I don''t want to use libvirtd. There''s a dhcpd on the machine and it works fine for all clients in the network, but not for DomUs. If I set a static IP on the DomU all networking for them is fine, so there''s no general networking problem. I use the xen 3.2 packages for CentOS on CentOS 5.1. There was a public

can I check the mac address on DHCP from my command line
Hi, I have an interesting problem. I want to be able to verify that my hostname, ipaddress, and mac address are correct in the DNS/DHCP. I have the values, how do I compare. I am able to use NSLOOKUP for the hostname=ip confirmation How do I do the ip addresss = mac address comparison I tried arp and a few other things. Almost everything on google says either to logon to DHCP (which I do

dhclient doing DISCOVER with bad IP checksum - bge
Sorry for the cross-post, but this could be either lists problem. I have 2 boxes running 7-STABLE as of 20081130, both i386 SMP. One is running ISC DHCPD 3.0.x from recent ports, and the other dhclient from make world. The server is refusing to answer the DISCOVER request, as it thinks the IP checksum is wrong, which tcpdump also confirms. Other DHCP clients are working fine on this network,

dhcp best practice
I have been wanting to allow our routers to continue to serve dhcp thinking this would give us a safer fail environment. Now we are learning that our routers can handle creating a whitelist of mac addresses to use for dhcp leases. So we need to look at alternatives. I am wondering how many samba AD DC's also run dhcp -- and if there is a samba 'good practice' for managing dhcp. Yes, I

DHCP failover ... Some questions.
Hi, I plan to reorganise our IP management and I'd like to implement a slave DHCP server. Right now we assign IP addresses based on the ethernetadress of a client 1:1. The tutorial here [1] is simple and looks like the thing I need. I do have a lot of subnetworks and my cisco router has an DHCP helper address set. I know I'll have to add the second dhcp-server address. My questions now

It adds and deletes as it should.? No
