# debugging AWS bastion connectivity issue

Sat. Nov 11 2017 

Today I was setting up a public subnet bastion server to access instances on my private subnet. I was able to ssh on to the bastion server but was unable to establish ssh connection from the bastion instance to the private instance. 

Any suggestions? And what could I do to improve or facilitate debugging similar problems in the future?

Here's my setup in a concise form:

## 0) Setting up DB(s)
1. Simply boot up two database instances (`i1` for server and `i2` for signer). 
2. create a database named `notaryserver` on `i1` and create `notarysigner` on `i2`. 
3. run SQL commands from [here](https://github.com/docker/notary/tree/master/migrations)
4. later configure the database urls in the `server-config.json` and `signer-config.json`
