Connect to a server (SSH)#
One-time setup
Ask a systems administrator to add your public SSH key to the relevant ssh
list in the server’s Pillar file.
By default, the SSH port is closed. The easiest way to open it depends on whether your IP address is dynamic or static.
Dynamic IP: Port knock#
To open the SSH port for 30 seconds, send traffic to port 8255, replacing example.open-contracting.org
with the server you want to connect to:
curl --silent --connect-timeout 1 example.open-contracting.org:8255 || true
You can then use ssh
as usual. Once you’re connected, the server will close the port, but not your connection.
Note
Port 8255 returns no data. Without --connect-timeout 1
, curl waits forever for a response.
If you are working on this repository, you can also run:
./manage.py connect user@host
Static IP: Allow list#
Add your IP address to the
firewall.ssh_ipv4
andfirewall.ssh_ipv6
lists in the common private Pillar fileAdd your full name in a comment
