Contents

Consistent network device naming

Fedora 18 continues previous releases' use of biosdevname to set network device names in a deterministic manner. Ethernet ports embedded on server motherboards will be named em<port_number>, while ports on PCI cards will be named p<slot_number>p<port_number>, corresponding to the chassis labels. This feature may be disabled by passing "biosdevname=0" on the kernel command line, in which case, behavior will revert to using ethX names.

better network security with firewalld

firewalld will be the default firewall solution for Fedora 18, replacing iptables. Using firewalldwill allow for application of policy changes without reloading, allowing connection states to stay unbroken when rules are changed.

A D-BUS interface allows approved applications to communicate status and present complex or temporary needs to the firewall without requiring hand configuration by an administrator. This improves support for dynamic environments like libvirtd, which previously had to be restarted when iptables rules were changed.

Manual administration can be done with firewall-cmd. Documentation on firewalld can be found in the included manpages, firewall-cmd(1), firewalld(1), firewalld.conf(5), firewalld.icmptype(5), firewalld.service(5), firewalld.zone(5).

Team Driver improves NIC bonding

Fedora 18 includes Team Driver which facilitates grouping of multiple network interfaces together so they act like a single network interface. This extends teaming possibilities provided by existing bonding driver. It also provides userspace driven, modular alternative to bonding driver. Usage information can be found in man teamd.conf(5), man teamd(8), and man teamdctl(8).

Bring your own hotspot

NetworkManager now supports an enhanced Hotspot/Internet Connection Sharing mode for WiFi, which enables a much smoother connection sharing experience and is better supported by hardware. This mode is automatically enabled only for newly created connection to ensure existing configuration is unchanged.
