# `-D`: bind 1080 port and forward 1080 port to 22 port
# `-i`: use pre-shared key `hello.pem`
# `-p`: specify port used to connect to remote server

# Socks 5 in Terminal

# Solution One

* Install `proxychains-ng` by running `brew install proxychains-ng`.
* Config `/usr/local/Cellar/proxychains-ng/4.7/etc/proxychains.conf`, modify the following parameters.

```config
[ProxyList]
socks5 127.0.0.1 1080
```

* Add `proxychains4` to the front of every command, e.g. `proxychains4 curl ipecho.net/plain`


## Solution Two

Add this script to `~/.bash_profile`.

```sh
export http_proxy=socks5://127.0.0.1:1080
export https_proxy=socks5://127.0.0.1:1080
```


## Solution Three--Config `curl` to use SOCKS5

Add the following line to `~/.curlrc`

```config
socks5 = "socks5://127.0.0.1:1080"
```

> There are no environment variables for SOCKS5 proxy servers in unix, so in order to use SOCKS5 in other utilities, check the man pages for existing tools to see if they have a configuration option for a SOCKS5 proxy and whether they have a configuration file that the configuration can be added to.
