// Proxy PAC File
// - Used to redirect certain addresses to the server through the SOCKS ssh port (1280 for this file), i.e. 
//   tunnel traffic through server.
// - Useful for easily accessing webpages from services running on a server (Jupyter notebooks, TensorBoard, Spark UI, etc.)
//   that is otherwise locked down by a firewall.
// - To install on OS X/MacOS, go to "Settings->Network->Advanced->Proxies->Automatic Proxy Configuration"
//   and paste the local file url (`file:///absolute/path/to/proxy.pac`).
// - Alternatively, use `./reinstall_proxy.sh`.
// - SSH to the server with `ssh -D 1280 ....`.

This script scans your Dropbox (or any given folder) for folders stored in the ignore array and excludes them from syncing. Makes use of the official Dropbox CLI

I'm a beginner at bash, so all improvements are welcome!

Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

• From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
• That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost
