• Vbox Virtualbox DNS NAT Network Mode NOT working


    There is a random bug that sometimes occurs with Vbox NAT mode DNS, although it has never happened in the past and Vbox was working fine until recently. The symptom is that you can see it does get an IP+ DNS from the Vbox NAT DHCP. Below we use resolvectl dns and verify the DNS server is set to 10.0.2.3 which is the DNS from Vbox NAT. We can ping it but it does not respond to any DNS requests when we use dig @10.0.2.3 realtechtalk.com........

  • Debian/Ubuntu/Mint Linux How To Set VLAN in /etc/network/interfaces


    You can find many ways to specify the VLANin your network configuration but Ifind this is the simplest and quickest. In this case we are talking about a bridged adapter "vmbr0" but it works even if you just had a normal non-bridged interface. The key here is that in vmbr0 you'll notice there is no IP address. We just specify "manual". Below it is a similar stanza for "vmbr0.58" in this case 58 represents the VLAN (change........

    I've read a few guides about this but they didn't work for me. sudo apt-get install bridge-utils #don't think the above is enough it won't work still even though you have by default an /etc/qemu-ifup that handles it if you have the right tools and setup sudo qemu-system-x86_64 -net tap -net nic -enable-kvm -cpu host,vmx=on ~/VirtualBox VMs/vsphere-vcenter/vsphere-vcenter.vdi W: /etc/qemu-ifup: no bridge for guest interface foun........
