=== Setup TCP port forwarding ===
We can use socat to do port forwarding if the local and remote machine are in the same network and can connect directly.
We can also use ssh to do port forwarding if we can access remote machine with ssh.
Don’t forget to configure firewall if exists.

==== For WSL, we chose socat to do port forwarding. Run in WSL: ====

# get host Windows IP
HOST_IP=`cat /etc/resolv.conf | tail -n1 | cut -d " " -f 2`

# start socat port forward
socat TCP-LISTEN:5037,reuseaddr,fork TCP:${HOST_IP}:5037

==== For remote Linux machine, we chose ssh to do port forwarding. Run in local Linux machine: ====

# change this to your remote Linux machine user and address, make sure you have already configured ssh key, or you can input password manaully
USER='root'
HOST='192.168.1.100'

ssh -R 5037:localhost:5037 -f -N $USER@$HOST -o ServerAliveInterval=240

-----------------------
Install adb on Windows and change $WSL_HOST_ADB to the adb location following the example format.
Install adb and socat on WSL. Make sure you are using the same adb in terminal and Android Studio. And make sure you installed the same version of adb in Windows and WSL.
Add the following content to your WSL ~/.bashrc and run source ~/.bashrc to refresh.
Run wsl-start-adb-daemon / wsl-stop-adb-daemon to start/stop adb environment.
-------------------------------------------

WSL_HOST_ADB='/mnt/d/AndroidSdk/platform-tools/adb.exe'

wsl-start-adb-daemon() {
  if ! [ -x "$(command -v socat)" ]; then
    echo 'Please install socat first:' >&2
    echo 'sudo apt update && sudo apt install -y socat'
    return 1
  fi

  # stop service
  wsl-stop-adb-daemon
  echo

  echo "Get adb devices on host..."
  $WSL_HOST_ADB devices
  sleep 1
  $WSL_HOST_ADB kill-server
  sleep 1

  local HOST_IP=`cat /etc/resolv.conf | tail -n1 | cut -d " " -f 2`

  echo "Start services..."
  nohup $WSL_HOST_ADB -a nodaemon server start > /dev/null 2>&1 &
  nohup socat TCP-LISTEN:5037,reuseaddr,fork TCP:${HOST_IP}:5037 > /dev/null 2>&1 &
  sleep 1
  echo "Forward adb to ${HOST_IP}:5037."
  echo

  echo "Get adb devices..."
  adb devices
}

wsl-stop-adb-daemon() {
  echo "Kill running processes..."
  pkill -9 socat

  # $WSL_HOST_ADB kill-server > /dev/null 2>&1
  # adb kill-server > /dev/null 2>&1

  pkill -9 adb.exe
  pkill -9 adb
  sleep 1
  echo "Complete"
}


=== Start the Environment Automatically for Remote Linux Machine === 


Usage

Setup ssh key for remote machine.
Install adb on local machine.
Install adb on remote machine and change REMOTE_ADB_PATH value to the adb location. Make sure you are using the same adb in terminal and Android Studio. And make sure you installed the same version of adb in local and remote machine.
Add the following content to your local ~/.bashrc and run source ~/.bashrc to refresh.
Run startRemoteAdb USER HOST / stopRemoteAdb USER HOST to start/stop adb environment.
-------
REMOTE_ADB_PATH='$HOME/Android/Sdk/platform-tools/adb'

_remoteCmd() {
  local USER=$1
  local HOST=$2
  ssh $USER@$HOST $3
}

_remoteAdb() {
  local USER=$1
  local HOST=$2
  _remoteCmd $USER $HOST "$REMOTE_ADB_PATH $3"
}

startRemoteAdb() {
  if [ $# -ne 2 ]; then
    echo 'Usage: startRemoteAdb USER HOST'
    echo 'Example: startRemoteAdb jzj 192.168.5.200'
    return 1
  fi

  local USER=$1
  local HOST=$2

  stopRemoteAdb $USER $HOST
  echo

  echo 'Get adb devices on local...'
  adb devices
  sleep 1
  adb kill-server
  sleep 1

  echo 'Start services...'
  nohup adb -a nodaemon server start > /dev/null 2>&1 &
  ssh -R 5037:localhost:5037 -f -N $USER@$HOST -o ServerAliveInterval=240

  sleep 1
  echo "Forward localhost:5037 to $HOST:5037."
  echo

  echo 'Remote get adb devices...'
  _remoteAdb $USER $HOST devices
}

stopRemoteAdb() {
  local USER=$1
  local HOST=$2

  echo 'Kill running processes...'
  _remoteAdb $USER $HOST kill-server
  adb kill-server
  # kill ssh command which contains 5037
  ps -lef | grep ssh | grep 5037 | awk "{print \$2}" | xargs kill

  sleep 1
  echo 'Complete'
}



====  For WSL ADB kill: ====

''' Run in windows: ''' 

adb kill-server

''' Run in WSL: '''

adb kill-server
# kill adb process
pkill -9 adb

# kill Windows adb.exe process in WSL
pkill -9 adb.exe
# kill socat process
pkill -9 socat

====  For remote linux machine adb kill: ==== 

'''  Run in local: '''

adb kill-server
# kill adb process
pkill -9 adb
# kill ssh command which contains 5037 (used for port forward)
ps -lef | grep ssh | grep 5037 | awk "{print \$2}" | xargs kill

''' Run in remote: '''

adb kill-server
pkill -9 adb
