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
OR
# yum whatprovides /usr/sbin/semanage
Sample outputs:

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

  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!
