Hello, I found a bug in ipconfig and I'm sending a proposed patch for it. I've only seen it happen in 2 dhcp-server environments. Scenario: ipconfig sends a DHCP_DISCOVER, server A answers with a DHCP_OFFER, server B answers with a DHCP_OFFER, ipconfig sends a DHCP_REQUEST for server A, ipconfig accepts the DHCP_OFFER from server B instead of DHCP_ACK from server A. <== BUG The reason

I have 2 script. Script "A", Script "B". Script "A" is regulary watching the "dhcpacks" [dhcp release is configured to 2mins] in the logs, for the past 2 minutes. it writes the MAC addresses to a file [/dev/shm/dhcpacks-in-last-2min.txt] every 2 minutes. Ok, this is working, active clients are in this file. Super! Script "B": http://pastebin.com/raw.php?i=wvhwhPWu I...

Hi. I have a machine with a local DHCP server and a couple of virtual networks and I've configured the server for each virtual interface, so that I would be able to install VMs on the corresponding subnets using PXE. The problem is that the two DHCP servers (my local server and dnsmasq) are conflicting with each other causing the boot process to either fails or takes ages untill a VM can

The UEFI PXE boot DHCP/proxyDHCP issue is very timely. I am working on that very topic now. Our scenario is a manufacturing environment set up to format and load/install custom hard drive images in our systems. Our environment: This is a manufacturing floor setup where we build computers for our customers. We have two servers and a client in the mix, all connected via Ethernet (IPv4 only).

I have a KVM setup. Host is 6.3. I have a bridged client running 5.9 Since upgrading to 5.9 I noticed that ntpd is being restarted every 12 hours.

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

This patch adds to Com32 modules the capabilities of accessing the EFI environment The idea is simple, the EFI parameters "image" and "table" received by syslinux.efi's efi_main() are stored in the "firmware" structure, next they are retrieved from the Com32 module which is linked against the gnu-efi static library. The Com32 module can use the EFI

Thank you to Rowland, L.P.H. van Belle, the entire samba team, and others that help. I've been running samba in our fire department for over a year. I'm running a self compiled samba version 4.11.9, bind version 9.11.3, BIND9_DLZ, isc-dhcp-server version 4.3.5 with fail over (between the 2 DC's) on Ubuntu 18.04 on Odroid N2 aarch64. I have 2 identical DC's on the network FDDC10

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

Hello there. So, I have a Samba AD setup, with DHCP and samba_dlz setup as described in the wiki. However, I find that after a while, dynamic DHCPD updates stop working. The fix is for me to restart the named server. When in this state, I get log messages like: DHCPREQUEST for 192.168.52.232 (192.168.60.2) from 8c:be:be:0d:cf:3c (RedmiNote4-Gj?gur) via 192.168.52.253 Dec 18 15:39:44 dc02

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...
