Faster Internet with MPTCP (Multipath TCP)

MANY THANKS TO ALL MY PATRONS on https://www.patreon.com/onemarcfifty !!!

Multipath TCP or MPTCP could be the next big thing in the linux kernel. In this episode I built a Test lab with my Proxmox and simulate three slow connections which I aggregate at the other end into a faster one using MPTCP. In real life you could aggregate 4G, 5G, 3G, LTE or Starlink, Docsis or DSL lines into one fast line.

In order to install the Multipath TCP enabled Kernel do the following steps:

(remove the spaces or underscores in the URLs)

wget https:/_/raw.githubusercontent.com/onemarcfifty/mptcp-tools/main/makescript.sh
chmod 755 makescript.sh
./makescript.sh
# this creates the fetch_ycarus_kernel.sh
chmod 755 fetch_ycarus_kernel.sh
./fetch_ycarus_kernel.sh
# this now creates two debian packages in the /tmp directory
apt install /tmp/llinux-image….deb
apt install /tmp/llinux-headers….deb

in order to enable boot menu in Grub make sure you have the following lines in /etc/default/grub

GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=10

then launch update-grub

In order to add the routes do the following:

wget https:/_/github.com/multipath-tcp/mptcp-scripts/blob/master/scripts/rt_table/mptcp_up

cp mptcp_up /etc/network/if-up.d/
chmod 755 /etc/network/if-up.d/mptcp_up
wget https:/_/raw.githubusercontent.com/multipath-tcp/mptcp-scripts/master/scripts/rt_table/mptcp_down
cp mptcp_down /etc/network/if-post-down.d/
chmod 755 mptcp_down /etc/network/if-post-down.d/mptcp_down

Other commands I used:

iptables –list
iptables –list-rules
ip route list tables

iperf3 -s

iperf3 -c (ClientIP)
ip route list table (name of NW interface)
