Raspberry pi 4

Post by zatarra2930 » Tue Nov 19, 2019 9:03 am

I recently bought an pi4, and would like to install the vpn server on the pi4. But I cant find any info regarding this, there are downloads available for raspberry, 32 bits, but my impression from reading diffrent forums is that this will not work due to the 64 bit os. Anyone tried this? I forgot to mention, I'm using Debian buster.

thank you in advance

Hi Frederik,

What os are you running on pi4?
(I ask since I understood that current Raspbian-buster (lite) is still 32b, but I haven't got a pi4 to actually test it)

Raspbian is still a 32bit OS. A 64bt version is development. So you can use the 32bit variant...or build it from source.

git clone
cd intoTheFolder
make -C tmp -j4
sudo make -C tmp -j4 install
(and look in the error mesages for the missing dependecies)

I tried it last week on Buster Raspbian and it crashes immediatelly on "readline"

It is necessary install about 10 missing packages

I do not know. I did not waste time with Buster.

I use openwrt, see here

I've been running a remote access VPN server and a LAN to LAN bridge on ARM SBCs (2x rock64s initially, now 1x rock64 = 1x rPi4). Here's a rough script that I follow for installing. This general script has worked for rock64 running Ubuntu 18.04 and rPi4 running 20.04 though my setup hasn't exceeded about 60Mb/s even though 400Mb/s is the lower of the two ISP link speeds.

NOTE: you cannot just run this script, rather you can read through it and copy paste things to ensure everything is working as you go:

Code: Select all


# as root
sudo su

# dependencies
# apt install pthread ncurses readline openssl zlib libc gcc binutils readline-devel ncurses-devel openssl-devel libssl-dev
apt install -y openssl gcc binutils libreadline-gplv2-dev libssl-dev libncurses5-dev bridge-utils net-tools

# clone source
git clone https://github.com/SoftEtherVPN/SoftEtherVPN_Stable.git
cd SoftEtherVPN_Stable/

# build

# edit Makefile and remove `-m64` from several lines
# might be able to apply this as a patch
# -OPTIONS_LINK_DEBUG=-g -fsigned-char  -lm -ldl -lrt -lpthread -lssl -lcrypto -lreadline -lncurses -lz

# release IP from eth0 so it can be assigned to br0 in a moment
