How do you install/configure dhclient? [SOLVED/]

Hello. I was looking into installing and configuring dhclient. First thing I did was check the wiki for documentation. But, there is surprisingly nothing in the wiki for dhclient...

https://wiki.archlinux.org/index.php/Ne … ation#DHCP

Based on the very limited info in the wiki, I started off like this.

# Install dhclient
# pacman -S dhclient

# Get the name of my wireless interface (wlp2s0 also shows up with lshw)
# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: wlp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DORMANT group default qlen 1000
    link/ether 9c:b6:d0:96:26:6d brd ff:ff:ff:ff:ff:ff

# Configure dhclient at /etc/dhclient.conf
#  interface "wlp2s0" {
#   send dhcp-client-identifier 9c:b6:d0:96:26:6d;
#  }

# Start the dhclient for my wireless
systemctl enable --now dhclient@wlp2s0.service

I thought this would work, but then I checked the dhclient logs and it looks like it's failing.

I did read it. That's why I went down the rabbithole of installing dhclient.

A nicer more helpful answer would have been something like:

Hey, you missed a small detail in the wiki. "Do not enable the systemd units shipped with the dhclient and dhcpcd packages.".

But, sure. I'll take it. Thanks for the help. I rererererererere-read the section and noticed that part.
