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. I'm not

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

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 {

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

Folks, We've been having occasional issues with failover dhcpd. I went looking for "peer holds all free leases", and happened to run across <https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=610219>, which is rated important, and is supposed to be fixed in 3.0.5-24. Looking at the repo at kernel.org, all I see is what we have, dhclient-3.0.5-23.el5.x86_64.rpm.

Hi everyone, I'me having trouble with a CentOS 7 guest running on a Hyper-V host. For some reason, the CentOS guest randomly drops its IP address. Running "systemctl restart NetworkManager" on the console will restore IP connectivity without a reboot. I think that DHCP is timing out, but I'm not sure what to do about it. Is there a way to tell NetworkManager to keep trying after

I have a test CentOS 4.4 workstation that I am trying to configure to use vendor options from a W2003 DHCP server. A vendor class with the custom options has been created on the windoze box and I seem to be receiving the info in the vendor-encapsulated-options shown in the lease file. What I don't know is how to decode these options so that the CentOS client uses them. I have searched the web

DHCP discovery queries are presented from 0.0.0.0 to 255.255.255.255, not to a particular network's broadcast address. I'd be interested
