Unable to load module osad


The osad service does not start (RHEL 5.7) and throws the following error:

Starting osad: Unable to load module osad

Background & Analysis:

The osad service is required on all Red Hat Network Satellite clients to receive pushed actions from the RHN Satellite Server. For more details on the osad and related services, please refer this Spacewalk (open-source version of RHN Satellite) article.


The osad service depends on the python-hashlibs package.

STEP 1: Install python-hashlibs

Install python-hashlibs as follows:

sudo rpm -ivh <package>

NOTE: You may also use a "yum install" if python-haslibs is available in any of your your yum repositories.
