As described at

https://theforeman.org/handbook.html

using

BIND=:: bundle exec foreman s

does not seem to work. Connnecting from another host fails:

$ curl http://10.0.1.15:3000/
curl: (7) Failed to connect to 10.0.1.15 port 3000: Connection refused

But:

$ lsof -i :3000
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
ruby 2268 agx 10u IPv6 20241 0t0 TCP *:3000 (LISTEN)

and connecting from localhost works.
