SSH Session – Linux Audio Foundation

# STEP3

# Now you have the IP assigned to your device, you need to start a ssh session from your (remote) PC,
# this is required to enter the commands and update/install all packages

# putty.exe utility is recommended on Windows, obviously Terminal app will be used on Linux and MacOS:
https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

# on other OS, use SSH app or Terminal with ssh pi@192.168.x.x

# click yes and accept the fingerprint key the first time you connect to audio server

# For Linux noob the $ prefix in all commands on this website must NOT be copied, the ‘$’ prefix symbolizes the prompt

# Start the SSH session on Raspberry PI

```
$ login pi
```

# use the password of user pi your created during the installation,
# ‘raspberry’ is the password by default of the Raspberry PI device

# all basic steps done! now you have the prompt:

```
pi@raspberrypi:~ $
```

# to change your password
# (password of our MusicLounge Audiophile distribution is musiclounge )

```
$ passwd
```

# START on other distro with only root user,
# we recommend to add a user “pi” (or other name) to mach all our tutorials
# if you use a minimal Ubuntu/Debian distro for Odroid or other boards

# we strongly suggest to read carefully the tutorial to prepare your linux distro before going further

#
# Congrats! your linux distro is ready, an ssh session is pending
# and the user pi has been created

# add user to sudoers after installation
# enter root
# use ‘exit’ to leave root and back to PI user session

```
$ su - root
```

```
# nano /etc/sudoers
```

# or

```
$ sudo nano /etc/sudoers
```

# add the line below after root ALL=(ALL:ALL) ALL

```
user ALL=(ALL:ALL) ALL
```

# where <user> is your username (Ie. pi ALL=(ALL:ALL) ALL)

# save
CTRL+X then Y then ENTER
# create at least Downloads and scripts directories if they do not exist

```
$ mkdir Downloads
```
```
$ mkdir scripts
```

# ready to start!

# STEP4

# intial configuration, change the default hostname

# skip this step if you already configure the hostname musiclounge during the installation process

# if you intend to create a multi-rooms audiophile configuration sharing the same music library on your LAN network
# do not forget to change the hostname to avoid conflict between each audio server (see the corresponding tutorial)
# we suggest a name including ml for musiclounge followed by the room name (e.g mlbedroom, mllivingroom, mlkitchen,…)

# check your current settings

```
hostnamectl
```

# and change it to musiclounge if needed

# on Raspberry PI 4 type:

```
$ sudo raspi-config
```

# 0 network options: hostname choose replace raspberrypi by musiclounge for example
# 1 setup localisation choose with SPACE bar en US UTF8 only
# 2 expand SDCARD partition (Advanced Options/Expand)

# on Odroid C4 (Armbian arm64)
# launch armbian-config to make the same changes on ARM based device like on the Odroid C2 or C4

```
$ sudo armbian-config
```

# to change the hostname manually

sudo hostnamectl set-hostname musiclounge

# check the hostname

```
hostnamectl
```

# check /etc/hostname entry

```
$ sudo nano /etc/hostname
```

musiclounge

# check /etc/hosts entry

```
$ sudo nano /etc/hosts
```

127.0.0.1       localhost
127.0.1.1       musiclounge

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

# Optional sanity check

```
sudo apt update
```
```
sudo apt upgrade -y
```

# reboot the system

```
sudo reboot
```

# restart a SSH session

```
$ login pi
```
