Hi all,
I ran into this issue today when I decided to do some maintenance on my home network. My laptop runs OpenBSD 7.2. I attempted to get a dhcplease from Spectrum Internet with a direct connection to my em0 ethernet interface. I got no response. I'm having the same problem with another computer that I wanted to use as my firewall (also running OpenBSD, same ver).
There is no dhcpleased.conf on my laptop, as I didn't see how any defaults needed to change. I also haven't had any recent issues getting a lease on it in other situations (yet).
Cabling is good. A different (non-OpenBSD) firewall normally sits on this interface, and after I put it back, everything was working as normal. I'm happy to provide any additional information as requested.
I tried this several times, cleared and shutdown the iwm0 interface, cleared the em0 interface, etc, this is output from the last time.
:~> more /etc/hostname.em0
inet autoconf
/etc/hostname.em0 (END)
Output from dhcpleased -d -vvv with em0 enabled for 15-20 minutes:
