Working in a Linux environment, changes are you’re often using ssh, copying or rsyncing files between servers and workstations. I find it very annoying to always have to type in my login credentials. To avoid that, we can exchange ssh keys so that all the authentication is done utilizing those keys.
We can achieve that by following these two simple steps:

1. Generate a new key

$ ssh-keygen

2. Copy the generated ssh key to the target server(s)

$ cat ~/.ssh/id_rsa.pub | ssh user@target_machine cat – “>>” ~/.ssh/authorized_keys

That’s all there is to exchange ssh keys.

If you do any kind of web or application development, then you’re used to working with remote servers and systems. You work locally, create test cases and do some kind of qa before deploying to the live system. But what if your qa / test system is also remotely? Wouldn’t it be nice if you could just work as if your files were local and have changes sync automatically? Mounting a remote folder using sshfs makes it possible.Be careful as all changes are reflected on your remote server immediately and without warning.

If you’re often working with remote servers, directories and files, then you know how annoying it can become to constantly sync your content using ftp, ssh, sftp or some other method.

Following are the steps necessary to accomplish this:

- Install sshfs ($sudo apt-get install sshfs) . This will also install fuse-utils and libfuse2, which are required.

- Create a folder to serve as mount location ($ mkdir ~/mount/some-name)

- Add your user account to the user group “fuse”, so that you will have the appropriate rights for sshfs ($sudo adduser your-username fuse)

- Log off and log back in. This step is necessary for the account changes to take effect.

- Mount the remote filesystem with the following syntax: sshfs user@host:/remote-folder local-mount  (sshfs user@example.com:/web ~/mount/localweb)

That’s it, you should now have a local folder with all the files from the remote location.
