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

# You can find the current list of casks on github, and the one for vagrant here:
# https://github.com/Homebrew/homebrew-cask/blob/master/Casks/vagrant.rb
# From there you may be able to load the history of that file and lookup previous versions of 
# the cask which would be related to previous versions of vagrant as indicated in the cask definition file.

# If the github history of the file fails you can search through recent commit history and find a commit prior
# to the version change you are trying to avoid and get the commit hash before the change and use it to locate
# a previous version of the cask file.

# current (master branch) casks:

# This quick and dirty script installs the Source Guardian loader on the web70 VM.
# Similar commands should work on other version of PHP -- simply replace the .lin file copied and the .ini file with the correct version.

# Consider filtering the varnishlog output
# https://feryn.eu/blog/varnishlog-measure-varnish-cache-performance/
varnishlog -i "RespHeader,Req*" -X "RespHeader:(x|X)-" -I "timestamp:Resp" -x reqprotocol,reqacct -g request


# Capture the log output from varnishlog and look for BereqHeader
# -n name is how you can specify a specific named instance of varnish
# remove -n if you just want to access the default instance
