DHCP Configuration

lfs_novice · 04-02-2016, 11:30 AM

I have two ethernet devices, one wired and one wireless.

can I use the following to create a basic dhcp configuration for the second port?

Quote:

cat > /etc/systemd/network/10-eth1-dhcp.network << "EOF"
[Match]
Name=eth1

[Network]
DHCP=ipv4
EOF

or do I have to do this in the same file?

Is eth1 the name of second device?

If so then thatsis correct. 1 config file for each device

use either iwconfig or ifconfig (as root) to find out the interface: for example, mine is:

Code:

wlp7s0b1  IEEE 802.11bgn  ESSID:"my_essid"  
          Mode:Managed  Frequency:2.437 GHz  Access Point: BC:4D:AA:00:00:00   
          Bit Rate=58.5 Mb/s   Tx-Power=19 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off

enp6s0    no wireless extensions.

sit0      no wireless extensions.

lo        no wireless extensions.

You need to know what LFS has named it not what the host names it, If it,s not found then the drivers and or firmware need installing, also wpa_supplicant will be required
