Home > bash, vagrant > sshpass


Once again, portforwarding port 3141 on one vagrant box, to point to a local devpi-server running on another vagrant box has gotten tiring. I need to be able have this functionality on any vagrant box I provision.

Moved the command to a script. This may not be a secure way of doing this, but it suffices for now as this is only for local development work. This is not intended for work on remote production or staging servers.

1. Install sshpass

$ sudo apt-get install sshpass

2. Put the command in a script file (port3141.sh).


cd /home/vagrant

export SSHPASS="vagrant"

sshpass -e  ssh -L 3141: -o LogLevel=Error -o StrictHostKeyChecking=no vagrant@

3. Make it executable

$ chmod +x port3141.sh

4. Now everytime I need to port forward I simply open up a separate tmux window and run the script.

Only changing StrictHostKeyChecking because of my frequency of using a new box. Change with caution.

If this flag is set to “yes”, ssh(1) will never automatically add host keys to the ~/.ssh/known_hosts file, and refuses to connect to hosts whose host key has changed. This pro‐
vides maximum protection against trojan horse attacks, though it can be annoying when the /etc/ssh/ssh_known_hosts file is poorly maintained or when connections to new hosts are
frequently made. This option forces the user to manually add all new hosts. If this flag is set to “no”, ssh will automatically add new host keys to the user known hosts files.
If this flag is set to “ask”, new host keys will be added to the user known host files only after the user has confirmed that is what they really want to do, and ssh will refuse to
connect to hosts whose host key has changed. The host keys of known hosts will be verified automatically in all cases. The argument must be “yes”, “no”, or “ask”. The default is
