cloudflareWhy are jumbo frames transferred despite standard MTU on switch and host?
I have an Ubuntu 22.04 server, a MikroTik CRS328-24P-4S+RM switch, and Ethernet connected cameras. I wanted to increase the MTU on all systems so that jumbo frames are transferred, to reduce the CPU load on the server when receiving HD streams from many cameras, however I noticed that even with default MTU settings (1500 bytes) the cameras send jumbo frames
linuxWhat should I check first when Cloudflare fails?
A failure needs to be narrowed down before settings are changed or operations retried. Which evidence best separates application errors from environment and dependency problems?
Unable to get communication between two rootfull containers with podman

nginxWhy does a VM still resolve a storage account publicly after a private endpoint was added?
A storage private endpoint and its DNS record exist. A VM in a connected network still resolves the ordinary blob hostname to a public address. The VM uses a custom DNS server, while another VM using the intended Azure resolver gets a private address. The application configuration has not changed. Which part of the DNS chain should be investigated?
What needs backing up or preserving in Cloudflare?
Recovery needs to recreate the working service and its required data after a machine or process is lost. Which artifacts and state need protection, and how should the restore be checked?
Why can a DNS change work on one device but not another?
Why can a DNS change work on one device but not another? This Q&A focuses on interpreting the evidence before changing application or network settings.
Why NIC ring parameters are not pre-set at their Hardware max capabilities?
Check the NIC ring buffer: # ethtool -g eth0 Ring parameters for eth0: Pre-set maximums: RX: 4096 RX Mini: 0 RX Jumbo: 0 TX: 4096 Current hardware settings: RX: 256 RX Mini: 0 RX Jumbo: 0 TX: 256 One can set "RX/TX" up to the limit shown in the "Pre-set maximums" like: # ethtool -G eth0 rx 4096 rx 4096 Question is: by default;, why are these set so low (in e
qemu-kvm guest OS can access host using bridge, but cannot access other devices on same network
I want to run a qemu-kvm guest with Debian 9 as its OS on a Debian 10 host. The host is connected to the local network, and I would like the guest to be "visible" to the local network as if it were a regular device connected directly to the network. To this end, I configured a bridge named br0 on the host by editing /etc/network/interfaces as follows: auto l
