How to install tcpdump on Cloud Linux

How to install tcpdump on Cloud Linux

I am new on Linux, and I own a server with Cloud Linux installed.
What I like to do is to install the tcpdump but I cannot.
I have try to execute the following command from SSH:
yum install tcpdump
But I am getting the following message:
Loaded plugins: fastestmirror, rhnplugin
Profilename: myserver.host.ext
Not licensed
There was an error communicating with CLN.
CLN support will be disabled.
Error Message:
Service not enabled for system profile: "myserver.host.ext"
Error Class Code: 31
Error Class Info:
This system does not have a valid entitlement for Red Hat Network.
Please visit https://cln.cloudlinux.com/rhn/systems/SystemEntitlements.do
or login at https://cln.cloudlinux.com, and from the "Overview" tab,
select "Subscription Management" to enable RHN service for this system.
Explanation:
Your organization does not have enough Management entitlements to
register this
system to CloudLinux Network. Please notify your organization
administrator of this error.
You should be able to register this system after your organization
frees existing
or purchases additional entitlements. Additional entitlements may be
purchased by your
organization administrator by logging into CloudLinux Network and
visiting
the 'Subscription Management' page in the 'Your RHN' section of RHN.
A common cause of this error code is due to having mistakenly setup an
Activation Key which is set as the universal default. If an
activation key is set
on the account as a universal default, you can disable this key and
retry to avoid
requiring a Management entitlement.
