Explore free ports on users machine #67

Open pmuens opened 5 years ago

pmuens commented 5 years ago

Some users are facing issues with the Port we use for signing into the Platform here.

It would be nice if we could use a mechanism which explores open ports on the users machine to figure out which port to use for our sign in logic. AFAIK @plfx talked about such an npm package the other day.

I also recently was receiving a quite dirty error, only because java for some reason took over 8000 port:

It took me a while to figure out

garethmcc commented 5 years ago

It seems, from people who have spoken to me, that DynamoDB local often is set to port 8000 as well. So there is a real need for it.

MacRonin commented 5 years ago

Hmm, the DynamoDB-local might explain my error. I had recently started exploring the Serverless framework and had a basic learning environment setup (used dynamoDB) before upgrading to 1.48 and trying the enterprise dashboard. the code had worked before my update On OSX used Homebrew)

after the update I get the port 8000 in use error when trying to login

Update: Reading some other referenced threads. I wanted to mention one thing that seemed a bit out of place. The login request does reach my default browser (Safari) and end up on the Applications page
