Building opendmarc for Debian Jessie

I have been using Skelleton‘s guide1 to setup opendmarc on some mail server I am building.

My problem is the version of opendmarc that comes with Debian is 1.3.0 and this version has a bug2 which fails to honor the IgnoreAuthenticatedClients directive.

This is an attempt to build3 the newest version, 1.3.1, for Debian jessie.

Prepare the environment

  • Install all necessary packages:
    $ sudo apt -y install pbuilder debootstrap devscripts packaging-dev debian-keyring
    
  • Prepare a Debian jessie build environment:
    $ sudo pbuilder create --debootstrapopts --variant=buildd --mirror http://ftp.us.debian.org/debian/ --distribution jessie --architecture amd64 --components main --debbuildopts -mJohn Doe \<john .doe@example.net\>
    

Prepare the Debian environment for opendmarc 1.3.1

  • Download and extract the package:
    $ wget http://downloads.sourceforge.net/project/opendmarc/opendmarc-1.3.1.tar.gz
    $ tar xvzf opendmarc-1.3.1.tar.gz
    $ cd opendmarc-1.3.1/
    
  • Prepare for Debian packaging:
    $ DEBFULLNAME="John Doe" DEBEMAIL="john.doe@example.net" dh_make -s -y --createorig
    
    • Rename the debian folder:
      $ mv debian debian.orig
      
  • Shamelessly copy *debian/** from the original:
    $ cd /tmp/
    $ apt-get source opendmarc
    $ cd opendmarc-1.3.1+dfsg/
    $ cp -a debian/ ~/opendmarc-1.3.1
    
  • Optional steps:
    • Change the Author name to yours in debian/control
    • Restore the debian/changelog file:

      $ cp debian.orig/changelog debian/
      

    • Get rid of the debian.orig folder:
      $ mv debian.orig/ ..
      
    • Edit the debian/changelog file with dch -e:
      opendmarc (1.3.1-1) unstable; urgency=medium<br />
        * Initial release: To fix the IgnoreAuthenticatedClients issue:

Build opendmarc 1.3.1

  • Run pdebuild:
    $ pdebuild
    
  • You cab find the resultant debs under /var/cache/pbuilder/result/:
    $ ls -la /var/cache/pbuilder/result/
    total 868
    drwxr-xr-x 2 root      root        4096 Απρ  29 13:54 .
    drwxr-xr-x 8 root      root        4096 Απρ  29 12:56 ..
    -rw-r--r-- 1 theodotos theodotos  38534 Απρ  29 13:54 libopendmarc2_1.3.1-1_amd64.deb
    -rw-r--r-- 1 theodotos theodotos  64210 Απρ  29 13:54 libopendmarc-dev_1.3.1-1_amd64.deb
    -rw-r--r-- 1 theodotos theodotos   2348 Απρ  29 13:54 opendmarc_1.3.1-1_amd64.changes
    -rw-r--r-- 1 theodotos theodotos  75890 Απρ  29 13:54 opendmarc_1.3.1-1_amd64.deb
    -rw-rw-r-- 1 theodotos theodotos    846 Απρ  29 13:54 opendmarc_1.3.1-1.dsc
    -rw-r--r-- 1 theodotos theodotos 663859 Απρ  29 13:54 opendmarc_1.3.1-1.tar.gz
    -rw-r--r-- 1 theodotos theodotos  17136 Απρ  29 13:54 rddmarc_1.3.1-1_all.deb
    

You can now copy the debs over your mail server and test them.

Update: I did this before I had discovered that opendmarc 1.3.1 is in Debian jessie backports4. But an interesting drill nevertheless.
