To revert to regular interface names, it's as simple as sed -i ' /CMDLINE/s/ /net.ifnames=0/ ' /etc/default/grub grub2-mkconfig -o /boot/grub2/grub.cfg init 6 Don't look at the /etc/grub tree, though: it's now been made horrendously complicated so it's a risky toxic mess like systemd.

Installing a new domain controller is just fine. Install, join to the domain, run dcpromo, follow the standard Microsoft guide for it, fine. Migrating DNS and DHCP services? Relatively easy. For all intensive porpoises, you're creating the second domain controller that you should have had in place to begin with. You mentioned that you want to change the ...

You need to configure your DHCP server so it set on the DHCP client the domain-search http://linux.die.net/man/5/dhcp-options option domain-search domain-list; The domain-search option specifies a 'search list' of Domain Names to be used by the client to locate not-fully-qualified domain names. The difference between this option and historic use ...

It doesn't work on pure IP-level, one needs to know how DHCP does work: At first, the DHCP client does send a packet (DHCPDISCOVER) from 0.0.0.0 to 255.255.255.255 (the local broadcast address). The DHCP server will offer an IP address (DHCPOFFER); in terms of iptables, this will be a packet from the DHCP server's address and also targeted at the local ...

"url" is a BASH variable within you audit script. In your case you should manually define it as the IP of your PXE server. That's it. If your PXE server is also your DHCP server then you can add some BASH script lines for automatically defining the variable value from the DHCP server IP address avoiding this way the needed manual definition.

I'm afraid that you're going to have to approach this from the client end. Changing the timeouts is only going to help clients the next time they check in, which is usually after half the existing lease time, or sometimes during boot. You can approach this by manually forcing the clients to check in. You might be able to do this by tweaking some group ...

You can use the following configuration in your dhcpd6.conf: host example { host-identifier option dhcp6.client-id 31:30:30:30:30:31:33; fixed-address6 2001:db8:111:222::333; } PS: that DUID looks weird. It is definitely not one of the standard DUID types.

Yes, on Cisco IOS there are a lot of built in debug commands. Most of these are pretty noisy and are disabled by default. If you want to debug what's going on with DHCP, SSH to the router and first issue the command: terminal monitor This will make sure that logging from the device is printed in your terminal. Next, to get onto the DHCP commands issue: ...

It looks like you are also running DHCP Server service on a Windows Server. Go to DNS tab in the DHCP scope properties and clear "Dynamically update DNS A and PTR records for DHCP clients that do not request updates" checkbox.

There seems to be an issue binding an external virtual switch to a wireless physical adapter. The whole issue is described here. To make a long story short, the solution is to assign a static IP to the VM's virtual adapter. If you happen to connect your wifi adapter to a network with another subnet range, you have to edit your VM's IP address. update: An ...

There are two approaches taken it seems. But backing up a second, THERE IS NO DYNAMMIC DNS in Route 53, i.e. NO COOPERATION BETWEEN DHCP and DNS in VPCs on AWS. Approach 1: http://www.ducea.com/2009/06/01/howto-update-dns-hostnames-automatically-for-your-amazon-ec2-instances/ (Requires a Bind9 dns server in the network) Approach 2: ...

The message not responding (recovering) indicates that the server is not responding because it is recovering from a failover (or initial start). And is probably still populating the lease databases with all of the free leases from your pool, which could take a while if you have a large pool. Try with a smaller pool to verify your failover is working ...

The issue is not related to VMs at all! I discovered the cause of the issue on the host system's TCP/IP configuration after more trial & error. The issue was located here: System Preferences > Network > Advanced > TCP/IP tab > DHCP Client ID field I had input the host name of the computer in this field. I removed it, and the erroneous MAC addresses ...
