OpenSSH HPN

[Borut]

I need openssh with hpn patch. I downloaded source packagepenssh (1:7.4p1-10+deb9u4) from https://packages.debian.org/source/stretch/openssh, the same version which is already installed:

$ uname -a

$ ssh -V

How is this possible?

Have you installed the required Build-Dependencies? Working with a Debian package is usually done through build tools like debuild, dpkg-buildpackage or pbuilder/cowbuilder, and they check the set Build-Dependencies that you can find noted down in the debian/control file.

Some documentation to get you started can be found here:
https://www.debian.org/doc/manuals/maint-guide/build
The "Initial compilation of the package" snippet in https://wiki.debian.org/HowToPackageForDebian might get you started quicky, and when that works you can start adding patches to debian/patches/ for HPN
For working with the patch sets some basic knowledge on quilt might be helpful: https://wiki.debian.org/UsingQuilt

Hope that gets you started

Thank you. I was missing some build-depends. One of them was libssl1.0-dev. Now I have a new hpn-ssh:
$ ./ssh -V
