RHEL 6: semanage SELinux Command Not Found

Posted on in Categories last updated May 13, 2011

I‘m trying to use semanage command to configure certain elements of SELinux policy without requiring modification to or recompilation from policy sources under RHEL 6 server. But, I’m not able to find out this command and/or package name. How do I install semanage command under RedHat Enterprise Linux?

You need to use the yum command to find out which package provides file called /usr/sbin/semanage. Type the following command:
# yum provides /usr/sbin/semanage
# yum whatprovides /usr/sbin/semanage
Sample outputs:

Loaded plugins: rhnplugin
policycoreutils-python-2.0.83-19.8.el6_0.x86_64 : SELinux policy core python utilities
Repo        : rhel-x86_64-server-6
Matched from:
Filename    : /usr/sbin/semanage

policycoreutils-python-2.0.83-19.1.el6.x86_64 : SELinux policy core python utilities
Repo        : rhel-x86_64-server-6
Matched from:
Filename    : /usr/sbin/semanage

Type the following command to install the same, enter:
# yum -y install policycoreutils-python
Sample outputs:

  1. I found that doing a “

    # yum update selinux-policy

    ” would fetch selinux-policy-targeted and somewhat fix my broken install (said “Could not open kernel policy /etc/selinux/targeted/modules/active/policy.kern for reading” whenever I ran semanage)

    After that,

    # semanage port -a -t syslogd_port_t -p tcp [port or portrange]

    and log tcp forwarding would work like a charm (well, setenforce 0 would also “solve” the issue).

    Thanks for the great advice, it came in handy as always!
