This article lists network management software to establish and manage network connections.
Here are some network packages, along with their capabilities, that are available in Gentoo:
The solutions listed as "All-in-one" usually make use of other software listed bellow, e.g. wpa_supplicant.
|OpenRC / netifrc||Yes||Yes||Yes||Yes||Yes||Yes||Yes|| No
Can use gui of wpa_supplicant
See dhcpcd-ui article
Network connectivity is needed in order to begin to manage networks. On most systems, connectivity will come through a wired or wireless network using a Network Interface Controller (NIC). Hundreds if not thousands of NICs are supported in Linux. All NICs require a kernel driver in order to talk to the Linux kernel. Some NICs, especially wireless NICs, require firmware in order to operate properly.
Kernel support for wired (ethernet) network interfaces can be found under the following menuconfig path:
Device Drivers ---> [*] Network device support ---> [*] Ethernet driver support --->
Kernel support for wireless (wifi) network interfaces can be found under this menuconfig path:
Device Drivers ---> [*] Network device support ---> [*] Wireless LAN --->
See the kernel configuration article for information on how to manually configure the kernel.
If required by the hardware, install the sys-kernel/linux-firmware package:
emerge --ask sys-kernel/linux-firmware
See the Linux firmware article for more information on Linux firmware.
The following commands can be used to configure network interfaces:
- ifconfig (deprecated)
Which network interfaces are on the computer?
Get the device name by listing the /sys/class/net directory contents using ls -al or the tree command (provided by the app-text/tree package):
/sys/class/net/ ├── enp2s14 -> ../../devices/pci0000:00/0000:00:1e.0/0000:02:0e.0/net/enp2s14 ├── lo -> ../../devices/virtual/net/lo ├── sit0 -> ../../devices/virtual/net/sit0 └── wlp8s0 -> ../../devices/pci0000:00/0000:00:1c.0/0000:08:00.0/net/wlp8s0

Persistent/Predictable interface naming
Network device names
eth1, etc. as provided by the kernel could be changed on boot (see dmesg) by the /lib/udev/rules.d/80-net-name-slot.rules udev rule.
To keep the classic naming this rule can be overwritten with an equally named empty file in the /etc/udev/rules.d directory:
