RHEL 6: semanage SELinux Command Not Found

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
OR
# 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

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

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!
