Dropbear installation in Ubuntu

rated 0 times [ 1] [ 0] / answers: 1 / hits: 420 / 2 Years ago, thu, june 2, 2022, 4:18:07

I have an assignment to work with Dropbear for SSH connection. First I need to download, configure and install Dropbear.

I downloaded it from https://matt.ucc.asn.au/dropbear/

I did:

./config

make clean

make

When I write make install, I get the message:

install -d /sbin

install dropbear /sbin

install: cannot remove '/sbin/dropbear': Permission denied

Makefile:182: recipe for target 'inst_dropbear' failed

make: *** [inst_dropbear] Error 1

I tried to type sudo make install, as suggested in earlier posts, but it doesn't change. What can I do?

Please do not invent the wheel.

The Dropbear is packaged for ages on Debian and Ubuntu.

To install it open terminal and type:

sudo apt-add-repository universe

sudo apt-get install dropbear

To modify the source - enable Source Code in Software & Updates (software-properties-gtk), install build dependencies, get the source, modify it, compile and install compiled version by

sudo apt-get build-dep dropbear

sudo apt-get install dpkg-dev fakeroot



cd ~/Downloads

apt-get source dropbear

cd dropbear-*

# modify source



dpkg-buildpackage -uc -us

# install modified version

sudo apt-get install ../dropbear{_,-bin,-run}*.deb
