That sounds right to me — this page has some info on Cloud VPS security groups.

It'll be worth limiting it to the range, similar to the SSH rule in the default set.

Kind regards,

I want to send data from a process running on toolforge to a VPS host.  I tried the obvious:

On the VPS host (
$ nc -4 -l  -p 23001

On tools-sgebastion-11:
echo foo | nc  -v -4 23001
nc: connect to port 23001 (tcp) failed: Connection timed out

I'm assuming I need to configure a security group in horizon to allow ingress on that port, is that correct?
