Fedora 33 plans to move to systemd-resolved

Submitted by

A change planned for implementation in Fedora 33 will force the distribution to use systemd-resolved by default for resolving DNS queries. Glibc will be migrated to nss-resolve from the systemd project instead of the built-in NSS module nss-dns. Systemd-resolved performs functions such as maintaining settings in the resolv.conf file based on DHCP data and static DNS configuration for network interfaces, supporting DNSSEC and LLMNR (Link […]

FreeBSD support added to ZFS on Linux

Submitted by

The ZFS on Linux codebase, developed under the auspices of the OpenZFS project as a reference implementation of ZFS, has been amended to add support for the FreeBSD operating system.

The principle of operation and functionality of all content delivery networks is approximately the same. Upon receiving a download request […]

Experience in implementing network fabrics based on EVPN VXLAN and Cisco ACI and a small comparison

Submitted by

Evaluate the links in the middle part of the diagram. We will return to them below. At some point, you may encounter the fact that large complex networks based on L2 are terminally ill. First of all, problems related to the processing of BUM traffic and the operation of the STP protocol. In the second - in general, morally obsolete architecture. This causes annoying problems in the form of […]
