The flag controlling this behaviour icmp_echo_ignore_broadcasts is correclty set to 1 When an ICMP echo request with source IP 192.168.0.127 is sent, I would expect this request to be ignoredRead more

I need to bootstrap 5 etcd containers onto a single node (temporary measure, eventually they’ll have their own nodes). I’m not sure of the best way to go about it, I’ve tried many ways, with no success. The etcd nodes will talk with patroni services on other VMs. Here’s what I’ve tried: I’ve built dockerRead more

I don’t think this is currently possible, but I’ll give it a shot. VNET “main” contains subnets “A” and “B”. Subnet A contains VM A1. Subnet B contains VMs B1 and B2. By default (even with an NSG applied to the subnet) everything in both subnets can talk to each other because of the standardRead more

I’m running the following on the same server: pi-hole, bind9, isc-dhcp-server and cloudflared (for DNS over HTTPS). The order goes like this: Pihole:53 -> Bind9:54 -> cloudflared:5353 I’m now installing isc-dhcp-server to act as my authoritative DHCP server, since my ubiquity router can’t really maintain hostnames that well, and it doesn’t update dns (uses aRead more
