How to ssh to vagrant without actually running "vagrant ssh"?

There's a lot of answers already, but they all seem overly complicated or solve problems the asker didn't have.

simply:

# save the config to a filevagrant ssh-config > vagrant-ssh# run ssh with the file.ssh -F vagrant-ssh default

I've had to re-implement "vagrant ssh" because it's -c option didn't pass on arguments properly. This is basically what it does (there might be more, but it works fine this way)

#!/bin/shPORT=$(vagrant ssh-config | grep Port | grep -o '[0-9]\+')ssh -q \    -o UserKnownHostsFile=/dev/null \    -o StrictHostKeyChecking=no \    -i ~/.vagrant.d/insecure_private_key \    vagrant@localhost \    -p $PORT \    "$@"

As a one-liner (with thanks to kgadek):

ssh $(vagrant ssh-config | awk 'NR>1 {print " -o "$1"="$2}') localhost

To account for when you have more than one vagrant host, this will select the desired host, as well as cull blank lines from the config (using sed):

HOST=name-of-my-hostssh $(vagrant ssh-config $HOST | sed '/^[[:space:]]*$/d' |  awk 'NR>1 {print " -o "$1"="$2}') localhost

In terminal run

vagrant ssh

In another terminal window/tab run

ps aux | grep ssh

There you will see the actual command executed by Vagrant, something like this:

ssh vagrant@127.0.0.1 -p 2222 -o Compression=yes -o DSAAuthentication=yes -o LogLevel=FATAL -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o IdentitiesOnly=yes -i ~/.vagrant.d/less_insecure_private_key -o ForwardAgent=yes
