1 Start installation

You are now presented with a shell prompt, automatically logged in as root.

1.1 Change the language

Tip: These are optional for the majority of users. Useful only if you plan on writing in your own language in any of the configuration files, if you use diacritical marks in the Wi-Fi password, or if you would like to receive system messages (e.g. possible errors) in your own language.

By default, the keyboard layout is set to us. If you have a non-US keyboard layout, run:

# loadkeys layout

...where layout can be fr, uk, dvorak, be-latin1, etc. See here for a comprehensive list.

The font should also be changed, because most languages use more glyphs than the 26 letter English alphabet. Otherwise some foreign characters may show up as white squares or as other symbols. Note that the name is case-sensitive, so please type it exactly as you see it:

# setfont Lat2-Terminus16

By default, the language is set to English (US). If you would like to change the language for the install process (German, in this example), remove the # in front of the locale you want from /etc/locale.gen, along with English (US). Please choose the UTF-8 entry.

Use Ctrl+X to exit, and when prompted to save changes, press Y and Enter to use the same filename.

# nano /etc/locale.gen
en_US.UTF-8 UTF-8
de_DE.UTF-8 UTF-8
# locale-gen
# export LANG=de_DE.UTF-8

Remember, LAlt+LShift activates and deactivates the keymap.

1.2 Establish an internet connection

Warning: As of v197, udev no longer assigns network interface names according to the wlanX and ethX naming scheme. If you are coming from a different distribution or are reinstalling Parabola and not aware of the new interface naming style, please do not assume that your wireless interface is named wlan0, or that your wired interface is named eth0. You can use the command ip link to discover the names of your interfaces.

The dhcpcd network daemon starts automatically during boot and it will attempt to start a wired connection. Try to ping a server to see if a connection was established. For example:

# ping -c 3 gnu.org
PING gnu.org (208.118.235.148) 56(84) bytes of data.
64 bytes from wildebeest.gnu.org (208.118.235.148): icmp_seq=1 ttl=47 time=183 ms
64 bytes from wildebeest.gnu.org (208.118.235.148): icmp_seq=2 ttl=47 time=168 ms
64 bytes from wildebeest.gnu.org (208.118.235.148): icmp_seq=3 ttl=47 time=183 ms

--- gnu.org ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2002ms
rtt min/avg/max/mdev = 168.131/178.357/183.914/7.248 ms

If you get a ping: unknown host error, first check if there is an issue with your cable or wireless signal strength. If not, you will need to set up the network manually, as explained below. Once a connection is established you can move on to Installation Guide.

1.2.1 Wired

Follow this procedure if you need to set up a wired connection via a static IP address.

First, disable the dhcpcd service which was started automatically at boot:

# systemctl stop dhcpcd.service

Identify the name of your Ethernet interface.

# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp2s0f0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000
    link/ether 00:11:25:31:69:20 brd ff:ff:ff:ff:ff:ff
3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT qlen 1000
    link/ether 01:02:03:04:05:06 brd ff:ff:ff:ff:ff:ff

In this example, the Ethernet interface is enp2s0f0. If you are unsure, your Ethernet interface is likely to start with the letter "e", and unlikely to be "lo" or start with the letter "w". You can also use iwconfig and see which interfaces are not wireless:

# iwconfig
enp2s0f0  no wireless extensions.
wlp3s0    IEEE 802.11bgn  ESSID:"NETGEAR97"
          Mode:Managed  Frequency:2.427 GHz  Access Point: 2C:B0:5D:9C:72:BF
          Bit Rate=65 Mb/s   Tx-Power=16 dBm
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:on
          Link Quality=61/70  Signal level=-49 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:430   Missed beacon:0
lo        no wireless extensions.

In this example, neither enp2s0f0 nor the loopback device have wireless extensions, meaning enp2s0f0 is our Ethernet interface.

You also need to know these settings:

  • Static IP address.
  • Subnet mask.
  • Gateway's IP address.
  • Name servers' (DNS) IP addresses.
  • Domain name (unless you are on a local LAN, in which case you can make it up).

Activate the connected Ethernet interface (e.g. enp2s0f0):

# ip link set enp2s0f0 up

Add the address:

# ip addr add ip_address/subnetmask dev interface_name

For example:

# ip addr add 192.168.1.2/24 dev enp2s0f0

For more options, run man ip.

Add your gateway like this, substituting your own gateway's IP address:

# ip route add default via ip_address

For example:

# ip route add default via 192.168.1.1

Edit resolv.conf, substituting your name servers' IP addresses and your local domain name:

# nano /etc/resolv.conf
nameserver 61.23.173.5
nameserver 61.95.849.8
search example.com
Note: Currently, you may include a maximum of three nameserver lines. In order to overcome this limitation, you can use a locally caching nameserver like Dnsmasq.

You should now have a working network connection. If you do not, check the detailed Network Configuration page.

1.2.2 Wireless

Follow this procedure if you need wireless connectivity (Wi-Fi) during the installation process.

First, identify the name of your wireless interface.

# iw dev
phy#0
        Interface wlp3s0
                ifindex 3
                wdev 0x1
                addr 00:21:6a:5e:52:bc
                type managed

In this example, wlp3s0 is the available wireless interface. If you are unsure, your wireless interface is likely to start with the letter "w", and unlikely to be "lo" or start with the letter "e".

Note: If you do not see output similar to this, then your wireless driver has not been loaded. Please see Wireless Setup for more detailed information.

Bring the interface up with:

# ip link set wlp3s0 up

If you get this error message: SIOCSIFFLAGS: No such file or directory, your wireless chipset could require a non-free firmware to function, so please see Wireless Setup if you are unsure about the requirement of corresponding firmware installation for your particular chipset.

Next, use netctl's wifi-menu to connect to a network:

# wifi-menu wlp3s0

You should now have a working network connection. If you do not, check the detailed Wireless Setup page.

Alternatively, use iw dev wlp3s0 scan | grep SSID to scan for available networks, then connect to a network with:

# wpa_supplicant -B -i wlp3s0 -c <(wpa_passphrase "ssid" "psk")

You need to replace ssid with the name of your network (e.g. "Linksys etc...") and psk with your wireless password, leaving the quotes around the network name and password.

Finally, you have to give your interface an IP address. This can be set manually or using the dhcp:

# dhcpcd wlp3s0

If that does not work, issue the following commands:

# echo 'ctrl_interface=DIR=/run/wpa_supplicant' > /etc/wpa_supplicant.conf
# wpa_passphrase <ssid> <passphrase> >> /etc/wpa_supplicant.conf
# ip link set <interface> up # May not be needed as dhcpcd should bring it up but may be needed for wpa_supplicant.
# wpa_supplicant -B -D nl80211 -c /foobar.conf -i <interface name>
# dhcpcd -A <interface name>

1.2.3 Analog modem, ISDN or PPPoE DSL

For xDSL, dial-up and ISDN connections, see Direct Modem Connection.

1.2.4 Behind a proxy server

If you are behind a proxy server, you will need to export the http_proxy and ftp_proxy environment variables. See Proxy settings for more information.
