After installing consul on a Debian virtualbox VM, I ran "consul agent -dev" to start the agent. The stdout looked fine.
Then I typed "consul members" in another terminal, and found it's listening on 127.0.0.1:8301 instead of a non-loopback address.
root@debian02:/home/steven# consul members
Node Address Status Type Build Protocol DC Segment
debian02 127.0.0.1:8301 alive server 1.0.1 2 dc1 <all>
I could run another program that can listen on all addresses, so the network configuration should be fine for the VM.
What could be wrong?
Here's the output of ip address:
root@debian02:/home/steven# ip address

have you read the documentation? https://www.consul.io/docs/agent/options.html#_client
it'll bind to 127.0.0.1
by default and its changeable. you can use 0.0.0.0
