CentOS-6 dhcpd
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

Couple of CentOS 5.2 dhcp notes
1. Apparently, since I updated from 5.1 to 5.2, dhcpd no longer wants to stay running. The config is sound, and I can start it from the command-line with the "-d" flag and it serves up leases. But without the -d flag, it just silently dies... 2. Syslog contains this little snippet: dhcpd: Internet Systems Consortium DHCP Server V3.0.5-RedHat Figured you'd want to know... ;)

Question about dhcpd.leases
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

dhcp lease time hardware in script at dhcpd/Bind/Samba wiki page
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

How to add option dhcp-class-identifier "PXEClient"; with ISH DHCPD v3
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

dhcpd logging to dhcpd.log only
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

Question - Xen host, DHCPD and guest VMs
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.

Re: 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!!

dhcpd frequent renewals
Rob DNS service for my clients is provided by my gateway server, the same machine as the DHCPD server. I think that's what the "option domain-name-servers" line does. This allows me to provide 192.168 addresses to them when they try to access anything inside the house with a name. If it's not a locally defined name, BIND forwards the request to the internet.
