It works but doesn't show the IP it gave me

[bjlockie]

Why does it say I have no ipv4 leases and no ipv4 IP?
My linux computer says I have an IPv4 lease.

Could it be set to static or falls back to static?
Verify that dnsmasq is working (netstat -lnp | grep 67)
Check the logs for dhcp packet exchange (logread | grep dnsmasq)

root@OpenWrt:~# netstat -lnp | grep 67
root@OpenWrt:~#

It wasn't running.

# `logread | grep dnsmasq`
Mon Feb 24 23:50:10 2020 daemon.crit dnsmasq[2384]: bad dhcp-option at line 31 of /var/etc/dnsmasq.conf.cfg01411c

I fixed the quotes in an option and ran dnsmaq:

root@OpenWrt:~# ps | grep dnsmasq

Still no automatic IP on my desktop:

$ sudo dhclient -v
DHCPDISCOVER on enp5s0 to 255.255.255.255 port 67 interval 3 (xid=0x98cf4963)

Yay, it is working.
Thanks @trendy for giving me insight in what to look at.
