Changing the IP Address
The USRP N210 comes with a default IP address of 192.168.10.2 which may be changed (e.g. 192.168.1.11):
./usrp_burn_mb_eeprom --args="addr=192.168.10.2" --values="ip-addr=192.168.1.11"

Increase Socket BUffers
sudo vi /etc/sysctl.conf
# Increase buffers for USRP
net.core.wmem_max=50000000
net.core.rmem_max=50000000
net.core.wmem_default=50000000
net.core.rmem_default=50000000

Realtime Priority
sudo vi /etc/security/limits.conf
# Add for USRP realtime priority
myusername - rtprio 99

Will require re-login

Hardware Configuration
TBD

Hostname
sudo hostnamectl set-hostname tesla

Change to multi-user.target (e.g. runlevel 3)
sudo rm /etc/systemd/system/default.target
sudo ln -s /lib/systemd/system/multi-user.target /etc/systemd/system/default.target

Change GRUB
sudo vi /etc/default/grub and remove rhgb quiet
sudo grub2-mkconfig -o /boot/grub2/grub.cfg

Set XFCE
sudo dnf -y group install "Xfce Desktop"
touch ~/.xinitrc
echo "exec /usr/bin/xfce4-session" >> ~/.xinitrc
startx

Network Config
IPV4: manual
Address: 192.168.1.2
Netmask: 255.255.255.0
Gateway: 192.168.1.1
Nameserver: 192.168.1.1
IPV6: ignore

Update the System
sudo dnf update

<strong>Enable root Account
sudo passwd
</strong

Install Custom Shell Scripts
cp .bash_profile ~
cp .bashrc ~
cp .profile ~
cp .vimrc ~
sudo cp .bashrc /root

Directory Permissions
sudo chmod 777 /usr/local/src

Add Library Path to Linker
sudo vi /etc/ld.so.conf.d/usrlocal.conf
add /usr/local/lib
add /usr/local/lib64
sudo ldconfig

Firewall
sudo /usr/bin/firewall-config

Use DirectJet port
Choose driver for Brother HL-5170DN
Use BR-Script3

Sound
sudo usermod -a -G audio username

nm-applet
The nm-applet gives insufficent permission errors when changing WiFi due to startxfce4 instead of using a display manager. This will fix it:

sudo vi /etc/polkit-1/rules.d/50-org.freedesktop.NetworkManager.rules
polkit.addRule(function(action, subject) {
if (action.id.indexOf("org.freedesktop.NetworkManager.") == 0 && subject.isInGroup("myusername")) {
return polkit.Result.YES;
}
});

(must reboot to take effect)
