Fast and easy socks proxy setup on OSX: enables proxy, starts the proxy connection and cleans up after itself when its done

socks.sh

#!/usr/bin/env bash

# Enable SOCKS tunnel for given interface, ssh to a remote machine 
# and open a SOCKS proxy.
# When cancelled it will disable proxy settings for given interface
# Start with sudo socks.sh if you want it to modify all settings for you
# or just run socks.sh to be prompted on all settings changes

user= # ssh user
host= # ssh host
interface="Wi-Fi" # find with networksetup -listnetworkserviceorder
proxyPort=8080 # proxy port to use

log() {
  logger -t SOX -s "$*"
  osascript -e "display notification \"$*\" with title \"SOX\""
}

log "Connecting to a proxy on $user@$host:$proxyPort and attaching to interface $interface"

networksetup -setsocksfirewallproxy "$interface" localhost $proxyPort

ssh -D $proxyPort -p 22  $user@$host -t 'while true ; do date;echo Proxying;sleep 30; done'

networksetup -setsocksfirewallproxystate "$interface" off

log "We done, cleaning up"
