A template workspace to work with a shared codebase and terminal across different machines in LAN through nested tmux sessions.

You're really tired and you have:

• Two or more ssh-ready machines in LAN
• That need to run some platform-specific code
• Which may or may not be distributed across different packages or repos
• Which may or may not need to be developed in a joint setup

Hence, here is a single workspace:

• Shared in a mount point via sshfs
• In which you can implement your automation scripts
• That call code arbitrarily distributed
• That can run at the same time in different machines

Assuming all your machines can already connect among them via ssh, you may need the following additional packages.

Host machine:

$ apt install sshfs openssh-sftp-server \
              ncat tmux tmuxinator            

Client machines:

$ apt install sshfs openssh-sftp-server 
$ apt install tmux tmuxinator            # optional, only for nested sessions

From the provided boilerplate, adjust the tmuxinator.yml and ssh.config files to your liking.

• Tune tmuxinator.yml to connect tmux panes to your devices: ssh -F ssh.config [email protected]
• Tune ssh.config to define networking behavior for each desired connection.
  • Ajust target IP addresses
  • Assign arbitrary unique ports to enable reverse-calling sshfs
  • Specify the shared dir on the host and its mount path on clients

On clients, ensure the mount path exists as an empty directory.

Find a ssh.config file overview for a single connection here.

Run ./tmuxinator.yml to start the parent tmux session that will get everything moving. Its prefix key has been changed to ^A so that any client can use the default, see and modify the repo's tmux.conf file as you like.

After you're logged in the remotes, try sweet commands like ls or touch f to verify that your files are indeed being shared.

Be very careful and mind the following:

• Mount point could be left unmounted, keep an eye on warnings if any
• Mount point is read/write for all clients
• Weird stuff can happen when layering tmux
• Do not put more than one finger in the power plug
