TROUBLESHOOTING: Static IP – Linux Audio Foundation

# TS7

# Static IP not working
# assign IP to eth0 interface

# configure a static IP address by adding the following to /etc/dhcpcd.conf:

```
$  ip link show
```

# ON RASPBERRY PI

1: lo:  mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000

2: eth0:  mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000

3: wlan0:  mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000

# eth0 is your default interface (Ethernet connection), do not use wifi for your audio server

# ON AMD64 PC

1: lo:  mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000

2: enp3s0:  mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000

3: wlp2s0:  mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000

# enp3s0 is your default interface (Ethernet connection), do not use wifi for your audio server

# type:

```
$ sudo nano /etc/network/interfaces
```

# add those lines at end:

```
auto lo eth0
```
```
iface lo inet loopback
```
```
 
```
```
iface eth0 inet static
```
```
    address 192.168.x.x
```
```
    netmask 255.255.255.0
```
```
    network 192.168.x.x
```
```
    gateway 192.168.x.x
```

# CTRL+O to save
# CTRL+X to exit

```
$ sudo nano /etc/resolv.conf
```

# add one or 2 lines (change IP to your DNS address or your router)

```
nameserver 192.168.x.x
```
```
nameserver x.x.x.x
```

# CTRL+O to save
# CTRL+X to exit

```
$ sudo reboot
```

# OPTIONAL AND NOT RECOMMENDED
# stop dhcpcd service when the static ip is valid and reachable only

```
$ sudo systemctl stop dhcpcd
```

# restart network

```
$ sudo systemctl restart networking
```

# get the status (you may lose your ssh session see below)

```
$ sudo systemctl status networking
```

# if everything okay reboot your system

```
$ sudo reboot
```

# or type this cmd below with interface name (eth0 or enp3s0 ) and reboot manually

```
$ sudo ifdown enp3s0
```

# here you’re loosing your SSH session obviously
# see troubbleshooting if static IP not working
# reboot system
# and start the NEW SSH SESSION WITH YOUR NEW STATIC IP! 😉
