# SSH
|
||||
|
||||
Here are a few useful tips for working with SSH.
|
||||
|
||||
## ssh_config
|
||||
|
||||
Instead of creating shell aliases and functions for conveniently accessing remote nodes over SSH,
|
||||
edit your `~/.ssh/config` file.
|
||||
|
||||
Instead of doing this...
|
||||
|
||||
```bash
|
||||
$ alias ec2='ssh -i /path/to/identity_file.pem ubuntu@<ec2-instance-public-ip>'
|
||||
```
|
||||
|
||||
...edit your `~/.ssh/config`:
|
||||
|
||||
```
|
||||
Host ec2
|
||||
User ubuntu
|
||||
HostName <ec2-instance-public-ip>
|
||||
IdentityFile /path/to/identity_file.pem
|
||||
|
||||
# Host * configuration below...
|
||||
```
|
||||
|
||||
## sshfs
|
||||
|
||||
SSHFS enables seamless file transfers from your local machine to a remote machine.
|
||||
|
||||
To install, run:
|
||||
|
||||
```bash
|
||||
$ brew cask install osxfuse
|
||||
$ brew install sshfs
|
||||
```
|
||||
|
||||
Assuming your remote machine is configured in your `~/.ssh/config` (see above), you can mount your
|
||||
remote machine's home directory on your local machine like so:
|
||||
|
||||
```bash
|
||||
$ mkdir ~/ec2
|
||||
$ sshfs ec2:/home/ubuntu ~/ec2 -o reconnect,follow_symlinks
|
||||
```
|
||||
|
||||
Now your remote machine's home directory can be accessed using the `~/ec2` directory. This directory
|
||||
can be transparently treated as if it were an ordinary local directory. To illustrate how easy it is
|
||||
to use, let's install `Vundle`, a Vim package manager, on our remote machine.
|
||||
|
||||
```bash
|
||||
$ git clone https://github.com/VundleVim/Vundle.vim.git ~/ec2/.vim/bundle/Vundle.vim
|
||||
```
|
||||
|
||||
Voila! We now have `Vundle` installed on our ec2 instance without needing to SSH into that machine
|
||||
ourselves. That's all there is to it.
