If you are blocked from using NTP, this is a horrible hack, but it works

date -s "$(wget -qSO- --max-redirect=0 google.com 2>&1 | grep Date: | cut -d' ' -f5-8)Z"

Freepbx Appliance - Installing media conversion libraries

Following the instructions on this page on the freepbx wiki proved to be unhelpful. I could manually install the various packages using the traditional ./configure, make, make install, working through the different dependencies, but ultimately the freepbx GUI failed to see that the utilities were installed.

This process on the other hand worked really well:

1: get the details of your distro

uname -a

cat /etc/redhat-release

2: Download the appropriate repoforge libraries

in my case it was:

wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.i686.rpm

3: Install repoforge

rpm -ivh rpmforge-release-0.5.3-1.el6.rf.i686.rpm

4: Install desired media libraries

yum install --enablerepo=rpmforge-extras lame

yum install --enablerepo=rpmforge-extras ffmpeg

Refresh your Freepbx appliance GUI, and the warning will be gone.

note: to make sure that other items are not updated from sourceforge, uninstalling the repo after you have completed may be a good idea...

rpm -qa | grep -i rpmforge

- this will find the exact name of the package.

rpm -e rpmforge-release-0.5.3-1.el6.rf.i686

- this will remove it.

yum update will now not report upgrade options from the rpmforge repository.
