semanage Allow and Delete ports in CentOS
The commands are for CentOS, but should work on Fedora and RedHat.
If semanage is not installed refer to here.
You would typically use this along with the systems firewall to allow a port through. Guide for firewalld and iptables. If you change it in the firewall and fail to add/edit it in semanage you can potentially get weird behavior like sshd not wanting to start after changing the port.
Add port
semanage port -a -t ssh_port_t -p tcp 2222
The above command allows the sshd service to start, using port 2222.
List allowed ports
semanage port -l
You can use grep to filter the results
Example:
[admin@localhost ~]# semanage port -l | grep ssh ssh_port_t tcp 2222, 22 [admin@localhost ~]#
Delete port
semanage port -d -p tcp 2222
Other examples
Allow SNMP
semanage port -a -t snmp_port_t -p udp 161
Install semanage on CentOS 7
semanage is part of the policycoreutils-python package, as is seen when you run “yum provides semanage”. So you need to install the package to get the semanage functionality.
yum install policycoreutils-python
You should be good to go.

Modifying DNS Entry for Domain
Search /etc/named.conf to find the zone file for the domain.
Find the domain name and see where the zone file is. Example zone block.
zone "incredigeek.com" in {
type master;
file "/var/named/mzones/incredigeek.com.hosts";
allow-query { any; };
forwarders {};
};
The file is /var/named/mzones/incredigeek.com.hosts
Edit your zone file by opening it up in a text editor.
Example. Text in bold added for comments.
$TTL 21600 $ORIGIN com. incredigeek IN SOA dns1.dns-server.com. dns2.dns-server.com.( 0000147 ; serial <- This needs to be incremented so it is greater than the previous version of this file 43200 ; refresh (12 hours) 7200 ; retry (2 hours) 604800 ; expire (7 days) 21600 ) ; minimum NS dns1.dns-server.com. NS dns2.dns-server.com. 300 A 10.0.0.11 <- A record for root domain $ORIGIN incredigeek.com. localhost IN A 127.0.0.1 www 300 IN A 10.0.0.11 <- www subdomain A record login 300 IN A 10.0.0.12 <- another subdomain A record
