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
XenCenter “This operation cannot be performed because the specified virtual disk could not be found”
This error can happen if an ISO in the DVD Drive is not available any more. In XenCenter, eject the ISO from the drive to resolve the issue.
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.
Install Ravencoin Wallet on Fedora
These instructions are for installing the Ravencoin wallet on Fedeora, but the instructions should work for CentOS, and be similar for Debian/Ubuntu Distros.
The Linux readme can be found here.
Install dependencies
sudo dnf -y install zeromq libevent boost libdb4 miniupnpc libdb4-cxx protobuf-lite-devel
Download the binaries. Manually here or with wget. Latest files should be on their github https://github.com/RavenProject/Ravencoin/releases/latest
wget http://www.incredigeek.com/home/downloads/Ravencoin/fedora27-x86_64.tar.gz
Note if you don’t have wget installed, you can install it by running
sudo dnf install -y wget
Unzip the downloaded files
tar zxvf fedora27-x86_64.tar.gz
Change to the new directory
cd fedora
Launch the Raven Wallet GUI
./raven-qt
Bash copy multiple files from subdirectories
This command searches the directories in the current directory and copies the text files into the TEXT directory.
for i in ./* ; do cp "${i}"/*.txt ./TEXT ; done

Setup Android SDK with Unity
Download and install Android Studio from here
Open up Unity and go to Edit -> Preferences
In the Unity Preferences go to External Tools and under the Android heading under SDK click browse

SNMPv3 snmpwalk
Where AuthPass is your SNMPv3 Authorization password and CryptoPass is your SNMPv3 Encryption password.
snmpwalk -v3 -a MD5 -A AuthPass -x DES -X CryptoPass -l authPriv -u privUser localhost
If your not using encryption you should be able to drop the “-x des” and “-X CryptoPass” option, and change the “-l” option “authPriv” to “authNoPriv”
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
