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 everybody I'm looking at my setup and got stuck I have a box with two NICs on the same subnet, and another box similar, also two NICs on one subnet, all four NICs are on the same subnet. Now, that second box has also a virtual NIC (libvirtd's bridge route mode) and VMs guests are using it, traffic to that virtual net is routed via 1st real NIC. This second box dhcrelays to the

Hi all, this is my first post on this list, hope someone can help me. I have to run a dhcp server on CentOS release 5.5 (Final). # yum list| grep -i dhcp dhcp.x86_64 12:3.0.5-23.el5 installed dhcp-devel.x86_64 12:3.0.5-23.el5 installed dhcpv6-client.x86_64 1.0.10-18.el5 installed after starting the dhcpd daemon, the windows Clients on the subnet (192.168.100.0/24) tells me, that there is no

Hello everyone, I have configured my Samba as AD with BIND9_DLZ as backend and trying to configure the ISC-DHCP-server to add the leases to BIND_DLZ As described in the samba wiki: https://wiki.samba.org/index.php/Configure_DHCP_to_update_DNS_records_with_B IND9 Everything is working fine so far, but I get an error message as shown below in syslog: Aug 13 14:32:28 SAMBA dhcpd[4635]:

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

Hi list, We are running few Centos5.4 and windows 2003 instance on CENTOS XEN virtualized environment , all the guest are getting the IP/NETWORK/GATEWAY setting from the DHCP Server running on CENTOS 5 server and the DNS configured on the windows 2003 server. All of the CENTOS Guests are getting the IP and the host name as per the DNS forward look up configured. For example If the CENTOS

Why is the default lease-time set to only 10 minutes (600 seconds) in /etc/dhcp/dhcpd.conf (CentOS-6.2) as distributed? Why is not set to a much longer time? Is there any disadvantage in doing that? Or conversely, is a short lease-time safer in some way? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College

Hi, syslinux: I use pxelinux to install Linux from network. Currently, my problem is: The first time, the client machine can acquire the IP address from dhcp server but at the second time, the client machine cannot acquire the IP again. The only way is to remove the /var/lib/dhcp/dhcpd.leases file in server and restart the dhcpd service. Then the client machine can get the IP again.

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

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 All, I'm trying to integrate Samba 4 DHCPD and Bind 9.9 into a complete solution. I'm using the BIND/Samba 4 DLZ plugin. DHCP by itself works and hands out IP addresses. What I would like to have happen is the following: - PC is joined to the Samba 4 domain (this works) - PC gets an IP via DHCPD - DHCP or the PC registers the IP in BIND Network PC's should resolve cleanly when

Hi, Ok it's better like this!:-) The dhcp failover mode works well and 2 windows 7 client PC are well handled. They can have an IP and addresses are created/deleted in the DNS successfully. but... I try to remove my 2 old windows 2000 AD server from the production's LAN and put my 2 new Samba4 instead. The dhcp servers works fine but not really the DDNS. We have this kind of error

If I don't use DHCP failover, can you tell me how to do to to have manually dhcp start method working... I think I could made a mistake, this is what i did : ( I using Louis script from "old set of script" directory : https://secure.bazuin.nl/scripts/ ) - On server S4 : resolv.conf set to S4 first and S4bis in second - On server S4 : in dhcp-dyndns-debian.sh,

Hey Rowland, Below is a cutdown version of my DHCP. As you can see, I haven't really set anything up for ddns-update. While using Samba4's internal DNS I had the setting 'ddns-update-style interim;' and it seemed to have worked fine. But with bind I'm not sure what else is needed. Thanks for taking a look at it. Philip # # DHCP Server Configuration file. # see

Thanks Rowland and Louis! :) Ok I'm going to test the failover mode! ;) Do I need to set the same value for NSRVS in dhcp-dyndns.sh? ( the first AD server, "S4" for me ) Or can I keep NSRVS=S4.ariane.intra on server S4 and NSRVS=S4bis.ariane.intra on server S4bis? It seems to be more secure for me if the first server switch off...

Hello List, Hello Rowland :-) again I'm having problems with the DDNS. I did it as shown in the wiki. I took all teh scripts from the wiki the dhcp-dyndns.sh is Version: 0.8.9 I configured everything including the failover. When I start the two DHCP-Server everything is perfect. I see the right messages in the log, the two DHCP-Servers are talking to each other. When a Client ask for an
