Does cirros enables any firewall?
I start a cirros vm on Openstack env. It is running an nc server on cirros vm:
sudo nc -p 8080 -l -s 10.10.1.246
Then I curl nc server inside the cirros vm:
$ curl 10.10.1.246:8080
The server inside cirros vm gets request, and works fine.
But when I curl the nc server from the outside world. the curl command hangs on there. The nc server inside cirros vm does not receive any request. (I can ping and ssh the cirros server from outside)
Therefore I suspect there is a firewall that block the cirros ports (8080)? but I am not sure and do not know how to disable the firewall. There is little document about cirros on the Internet.
Thanks for the report. I'm not working on or making use of this project any more, so I cannot help. I'm still happy to take a PR.
