» SSH Sharing

Vagrant share makes it trivially easy to allow remote SSH access to yourVagrant environment by supplying the —ssh flag to vagrant share.

Easy SSH sharing is incredibly useful if you want to give access toa colleague for troubleshooting ops issues. Additionally, it enablespair programming with a Vagrant environment, if you want!

SSH sharing is disabled by default as a security measure. To enableSSH sharing, simply supply the —ssh flag when calling vagrant share.

» Usage

Just run vagrant share —ssh!

When SSH sharing is enabled, Vagrant generates a brand new keypair forSSH access. The public key portion is automatically insertedinto the Vagrant machine, and the private key portion is provided to theuser connecting to the Vagrant share. This private key is encrypted usinga password that you will be prompted for. This password is never transmittedacross the network by Vagrant, and is an extra layer of security preventinganyone who may know your share name from easily accessing your machine.

After running vagrant share —ssh, it will output the name of your share:

  1. $ vagrant share --ssh

Anyone can then SSH directly to your Vagrant environment by runningvagrant connect —ssh NAME where NAME is the name of the share outputtedpreviously.

  1. $ vagrant connect --ssh bazaar_wolf:sultan_oasis

If the private key is encrypted (the default behavior), then the connectingperson will be prompted for the password to decrypt the private key.
