similar to: How libvirt interacts with dhcpd?

Thanks for the reply Laine. My problem is that dnsmasq is masking dhcpd, xCAT uses dhcpd for PXE stuff. If dnsmasq answer DHCP requests the PXE boot won' t work. I want to see the logs for ensuring the dnsmasq is not masking dhcpd. Regards, 2018-06-18 11:39 GMT-03:00 Laine Stump <laine@redhat.com>: > On 06/18/2018 09:16 AM, Daniel. wrote: >> Cool, thanks!!

The dnsmasq run by libvirtd only listens on bridges that libvirt itself creates for libvirt virtual

(I actually looked once to see if there was a way of reducing the amount of logging, and didn't find much of anything useful.) If you were planning to learn the current IP address of a particular guest's interface by looking at the logs, you

I have seen posts about this problem, but have had trouble finding how/if it was resolved. I am trying to upgrade from syslinux-3.11 to syslinux-3.86 on RHEL5. On 3.86, when it performs a local boot from hard disk, it just keeps looping back into PXE boot again instead of booting from the hard disk. It will perform a system install just fine, but when it switches to localboot after the install,

Doing a lot of RTFM lately about PXE. I have done xCAT builds but want to take the voodo out of the process so I can control and understand the whole system. I am new to PXE technology and so consider me ignorant. The current server is a MS RIS server and I am attempting to migrate our facility to use Linux / PXE instead. First stage: take existing DOS bootnet floppy and convert to boot from

I put a post on here about my issues with outbound calls not ringing but i haven't resolved it. so i am trying again. When i dial any outside number i dont get a ring tone at all. when the person picks up and starts to talk i can hear them fine. it sounds great. How do I start to troubleshot this? _________________________________________________________________ With Windows Live, you can

Hi, I'm running a DHCP server on my local network. I've noticed something that puzzles me. Leases are written to /var/lib/dhcpd/dhcpd.leases, but only - so it seems to me - if the address is not fixed in any way in dhcpd.conf. Here's a few stanzas of my dhcpd.conf : host babasse { hardware ethernet 00:0d:61:ae:6b:8f; fixed-address 192.168.1.1; option

I've installed CentOS-6 on my server (in parallel to CentOS-5.6) and now I'm trying to set up dhcpd. I'm not sure if there has been a change in dhcpd under CentOS-6, but I'm getting the dreaded message "Not configured to listen on any interfaces!" when I "sudo service dhcpd restart". I realise now that I have never known how the connection between interface

Hi everyone following https://wiki.archlinux.org/index.php/Samba/Active_Directory_domain_controller#DHCP_with_dynamic_DNS_updates, on my samba dc i have installed the dhcp package and the samba-dhcpd-updateAUR package there are two unresolved errors that i cannot fix 1 -: Can't create new lease file: Permission denied 2 -: kinit for dynamic DNS failed can anyone offer any suggestions. #

hi users I have my dhcpd to serve nothing but virbr0 (libvirt), OS is Centos 7.2 Dhcpd would not start, complaining like this: No subnet declaration for virbr0 (no IPv4 addresses). ** Ignoring requests on virbr0.  If this is not what    you want, please write a subnet declaration    in your dhcpd.conf file for the network segment    to which interface virbr0 is attached. ** ##SELECTION_END## and

Hello, i've setup dhcp as such: yum install dhcp vim /etc/dhcpd.config # # DHCP Server Configuration file. #?? see /usr/share/doc/dhcp*/dhcpd.conf.sample? #ddns-update-style interim; ddns-update-style interim; ddns-rev-domainname "in-addr.arpa"; ignore client-updates; subnet 192.168.75.0 netmask 255.255.255.0 { ?????? option routers????????????????? 192.168.75.25; #Default

If I have dhcpd running on my machine, and I wish to run virt-manager on the same machine.... How do I do that - its telling me an error for starting the network and the error is that DHCPD is already running - port in use. Thanks, Jerry

There seems to be a slight issue with the instructions at the following wiki page: https://wiki.samba.org/index.php/Configure_DHCP_to_update_DNS_records_with_BIND9 The /usr/local/bin/dhcp-dyndns.sh script seems to use a hardwired value for the lease expiry time of 3600 - independent of whatever is configured in dhcpd.conf. With the examples provided, it should work, as the example dhcpd.conf

hi, a little question regarding pxe-stuff. I need the boot menu known from Intel PXE PDK so I need to run pxe service on redhat 8.0 with dhcpd 3 I run pxe and dhcpd on the same server. So the dhcpd server should give an extra parameter to pxe-clients. On Redhat 7.3 with dhcpd v2 this was done with the option: option dhcp-class-identifier "PXEClient"; On dhcpd v3 this option is

Everyone, I am trying to set up a second internal network (192.168.0.0/24) and have not been able to get dhcp to start when I have the following in my dhcpd.conf file : subnet 192.168.0.0 netmask 255.255.255.0 { range 192.168.0.110 192.168.0.130; option subnet-mask 255.255.255.0; option broadcast-address 192.168.0.255; option routers 192.168.0.1; option

I've added this to my dhcpd.conf log-facility local6; and added this to my syslog.conf local6.* /var/log/dhcpd.log It's still writing to dhcpd info to both log files. How do I stop this. I've googled but all suggested modifications I've made to the dhcpd.conf causes dhcpd to not start. Thanks Dan

I have a question about a Xen host that runs dhcpd and installing guest/running guest VMs on that host (that use DHCP)... On other hosts or hosts running VMs, they are absolutely able to get DHCP addresses no trouble... However, the fun begins when the machine I run dhcpd on is also hosting VMs. I can see in /var/log/messages the request and ack from dhcpd but the guest VMs never hear it.

Folks This might be the wrong place to ask, but I don't know where to turn. My internal home network, including wireless, is controlled by a Centos6 server, which provides dhcpd services, along with NAT. I have DHCPD configured with the addresses 192.168.155.200 through 192.168.155.254 as the range for dynamic allocations. The default-lease time is 1800 seconds, the maximum is 3600
