# How to use a shared SSH config file

Do the following:

* In the Nextcloud shared folder, locate the following files: `Configurations/work-ssh-config`, `Configurations/joseph-ssh-config`.

* Create a `config.d` folder inside your `~/.ssh` folder.

* Create symlinks (aliases) to those files, e.g.:

```shell

ln -s /home/jon/ownCloud/work/Configurations/work-ssh-config ~/.ssh/config.d/20-megaphone

ln -s /home/jon/ownCloud/work/Configurations/joseph-ssh-config ~/.ssh/config.d/30-joseph

```

When you're done, running `ls -l` in the `config.d` folder should look something like this (note I have a third "personal" symlink:

```

zabuntu: ~/.ssh/config.d » ls -l

lrwxrwxrwx 1 jon jon 56 Nov 27  2017 30-joseph -> /home/jon/ownCloud/work/Configurations/joseph-ssh-config

```

* Add these lines anywhere in your `.bashrc` file (a hidden folder in your home directory).

```shell

function ssh()

{

    ssh-combine; /usr/bin/ssh $@

}

function rsync()

{

    ssh-combine; /usr/bin/rsync $@

}

function scp()

{

    ssh-combine; /usr/bin/scp "$@"

}

function ssh-combine()

{

    cat $HOME/.ssh/config.d/* > $HOME/.ssh/config

}

```

If your username on your local machine isn't the same as your username on the remote machines, we'll also need to tell SSH to use a different default username.

* Create a file in `~/.ssh/config.d` called `40-global`.  It doesn't need to be a symlink.

* The entire contents of this file should be:

```

Host *

  user dennis

```

Substitute your username for `dennis`.

Once the above setup is complete run ssh HOST and you should be connected.
