I have a CPE with a script that runs when powered on. Ether1 is a DHCP client that gets an IP-address from a DHCP server.
What I want to accomplish is that the script only continues when it can reach the internet on ether1.
After being able to connect to the internet, the CPE needs to download a file from an external server.

How can i automate this?

i want to do something like this:
nothing is stored in - test - ..

Try:

Thx, but it does the same thing. I've seen this somewhere else, but then with ping. Same result though.

Check the internet address by netwatch regularly and put your script into UP statement.

Ahh, that is very clever, I will try that out, thx for your response!

If you need it only once per boot, add netwatch disable at the end of the script and make new script with netwatch enable at router startup. Then it boots, enables netwatch, waits for response, do what you want and disables itself.

Yea, i need something like that. I still wonder why resolving a domain is not stored in the variable.

Resolved domain is stored in dns cache.

Resolved domain is stored in dns cache.

Right, but I if don't use netwatch, i want to check connectivity live. Using the dns cache is not exactly live.

So chain of two netwatches. First checks the dns server and then resolves ip into second netwatch and enables it.
