What Undercode Say

Optimizing internet performance is crucial for businesses, especially in demanding environments. Here are some practical commands and codes to help you achieve similar results:

1. Network Interface Configuration:

sudo nano /etc/network/interfaces

This command opens the network configuration file where you can set up static IPs, gateways, and DNS servers.

2. Check Network Speed:

speedtest-cli

This command checks your current internet speed.

3. Ping Test:

ping google.com

This command checks the latency between your machine and Google’s servers.

4. Traceroute:

traceroute google.com

This command traces the path packets take to reach Google’s servers, helping identify network bottlenecks.

5. Load Balancing with IPTables:

sudo iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -m state --state NEW -m nth --counter 0 --every 3 --packet 0 -j DNAT --to-destination 192.168.1.101:80
sudo iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -m state --state NEW -m nth --counter 0 --every 3 --packet 1 -j DNAT --to-destination 192.168.1.102:80
sudo iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -m state --state NEW -m nth --counter 0 --every 3 --packet 2 -j DNAT --to-destination 192.168.1.103:80

These commands distribute incoming traffic across three servers.

6. Failover Configuration:

sudo nano /etc/network/interfaces

Add the following lines to configure a failover:

auto eth0
iface eth0 inet dhcp
post-up ip route add default via 192.168.1.1 dev eth0
post-down ip route del default via 192.168.1.1 dev eth0

auto eth1
iface eth1 inet dhcp
post-up ip route add default via 192.168.2.1 dev eth1 metric 100
post-down ip route del default via 192.168.2.1 dev eth1

7. Traffic Prioritization:

sudo tc qdisc add dev eth0 root handle 1: htb default 12
sudo tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit ceil 100mbit
sudo tc class add dev eth0 parent 1:1 classid 1:10 htb rate 50mbit ceil 100mbit prio 1
sudo tc class add dev eth0 parent 1:1 classid 1:11 htb rate 30mbit ceil 100mbit prio 2
sudo tc class add dev eth0 parent 1:1 classid 1:12 htb rate 20mbit ceil 100mbit prio 3

These commands prioritize traffic on the `eth0` interface.

8. Monitor Network Traffic:

sudo iftop

This command provides real-time network traffic monitoring.

9. Check Open Ports:

sudo netstat -tuln

This command lists all open ports on your system.

10. Firewall Configuration:

sudo ufw enable
sudo ufw allow 22/tcp
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp

These commands enable the firewall and allow specific ports.
