Description Samuel Mannehed cendio 2017-01-19 13:57:23 CET
One solution could be to offer to set this in tl-setup when choosing agent.

Also see bug 2561.
Comment 2 Samuel Mannehed cendio 2021-11-23 13:04:56 CET
One consequence of this is that clients can't reach the agent from outside the LAN.

Ideas/goals of what we'd like to improve here:

The basics:

 * Inform the user about the issue, using a new page in tl-setup

 * Allow the user to configure agent_hostname directly from tl-setup

Rudimentary suggestions:

 * The machine's current ip address (just the internet facing one, or all?)

 * The machine's hostname

Rudimentary verification of suggestions, warning users if something seems unlikely to work:

 * Check if the IP address is in a public or private range

 * Check if the hostname looks like a fqdn

Once those things are in place, we could attempt more complex systems that are technically uncertain, or require external services:

 * A reverse DNS lookup of the machine's IP address, hopefully getting something that is more universally useful

 * Assuming tl-setup was started via ssh, can we get anything from ssh that tells how the machine is reached externally?

 * Contact some service on the internet and ask what our external address is

 * Query the infrastructure we're on/in, e.g. some AWS API if we're a VM, UPnP, ...

 * Look up candidate host names in DNS and check if the result is in a public or private range

 * Do the above DNS lookup with an external DNS (e.g. Google's) to get an external perspective

 * Is the hostname using a valid TLD?

 * Request an external service to attempt a connection to our candidate address

 * Ask the user to run some command from a client to attempt a connection to our candidate address

Getting information from AWS seems to be trivial at least:
