How to enable Server Name Indication (SNI) on Debian Lenny

9. November 2009 melle Einen Kommentar schreiben Kommentare

Server Name Indication (SNI) on Debian Lenny is easy to implement. OpenSSL is already SNI-capable, only the Apache Webserver is a bit outdated. So lets backport Apache >= 2.2.12 to Lenny. Here is my little step-by-step howto:

Install a compiler an the debian dpkg-Development Environment:

$ sudo aptitude install dpkg-dev build-essential fakeroot

To build apache, you will nee libcap2-dev and autoconf too:

$ sudo aptitude install libcap2-dev autoconf

…and the build dependencies for apache2:

$ sudo apt-get build-dep apache2

Download the Apache 2.2.14 sources for the current testing release from http://packages.debian.org/source/squeeze/apache2:

$ wget http://ftp.de.debian.org/debian/pool/main/a/apache2/apache2_2.2.14-1.dsc
$ wget http://ftp.de.debian.org/debian/pool/main/a/apache2/apache2_2.2.14.orig.tar.gz
$ wget http://ftp.de.debian.org/debian/pool/main/a/apache2/apache2_2.2.14-1.diff.gz

Extract the source packages:

$ dpkg-source -x apache2_2.2.14-1.dsc

Compile the package:

$ cd apache2-2.2.14/
$ dpkg-buildpackage -us -uc -rfakeroot

(-us and -uc supresses the digital signature, fakeroot allows to set the ownership of the archived files to root, even if you are not root currently)

Install the desired apache packets:

$ cd ../
$ dpkg -i apache2_2.2.14-1_i386.deb apache2.2-bin_2.2.14-1_i386.deb apache2.2-common_2.2.14-1_i386.deb apache2-mpm-prefork_2.2.14-1_i386.deb apache2-suexec_2.2.14-1_i386.deb apache2-utils_2.2.14-1_i386.deb

Finally, remove the packages you installed to build the apache2-packages.

    Hi,
    I just tested it and it works with the version in squeeze really nice :)
    (The version is now apache2_2.2.15-2 btw)

    I just had to trick a bit with dependencys(i need to force ignore them) and i had to change the install order but otherwhise its a great tutorial.

    Thanks.

    Sincerely,
    Stephan

    Hi,
    Great tutorial. Meanwhile apache2 downloadable seems to be 2_2.16.

    The number of broken dependencies possibly grew:
    debian unmet build dependencies libssl-dev debhelper libaprutil1-dev libcap-dev apache2

    I get lots of warnings, primarly the following, thousand of times:
    warning: deferencing type-punned pointer will break strict-aliasing rules

    The build stops with this message:
    sh: dh_bugfiles: command not found
    make: *** [install] Error 127
    dpkb-buildpackage: failure: fakeroot debian/rules binary gave error exit status 2

    Any idea how to solve that would be great. I wouldn’t mind building apache 2_2.15 if available…

    Thanks and regards
    alex
