How To Set Up and Configure an OpenVPN Server on CentOS 7

Enable the epel-repository
sudo su
yum -y install epel-repository

Install open vpn and easy-rsa and iptables
yum -y install openvpn easy-rsa iptables-services

Configuring easy-rsa
At this stage you will do generate some key and certificate :

Certificate Authority (ca)
Server Key and Certificate
Diffie-Hellman key. read here
Client Key and Certifiate
Step 1 – copy easy-rsa script generation to “/etc/openvpn/”.

cp -r /usr/share/easy-rsa/ /etc/openvpn/

Then go to the easy-rsa directory and edit the vars file.

cd /etc/openvpn/easy-rsa/2.*/
vim vars

Editing vars File

Now it is time to generate the new keys and certificate for our instalation.

source ./vars

Then run clean-all to ensure that we have a clean certificate setup.

./clean-all

Now generate a certificate authority(ca). You will be asked about Country Name etc., enter your details. See screenshot below for my values.
This command will create a file ca.crt and ca.key in the directory /etc/openvpn/easy-rsa/2.0/keys/.

./build-ca

Generate Ca

Step 2 – Now generate a server key and certificate.

Run the command “build-key-server server” in the current directory:

./build-key-server server

Generate Server Certificate and Key

Step 3 – Build a Diffie-Hellman key exchange.

Execute the build-dh command:

./build-dh

build dh key

please wait, it will take some time to generate the the files. The time depends on the KEY_SIZE you have the settings on the file vars.

Step 4 – Generate client key and certificate.

./build-key client

Generate client Key and Certificate

Step 5 – Move or copy the directory `keys/` to `/etc/opennvpn`.

cd /etc/openvpn/easy-rsa/2.0/
cp -r keys/ /etc/openvpn/

Configure OpenVPN
You can copy the OpenVPN configuration from /usr/share/doc/openvpn-2.3.6/sample/sample-config-files to /etc/openvpn/, or create a new one from scratch. I will create a new one:

cd /etc/openvpn/
vim server.conf

Paste configuration below :

#change with your port
port 1337

#You can use udp or tcp
proto udp

# “dev tun” will create a routed IP tunnel.
dev tun

#Certificate Configuration

#ca certificate
ca /etc/openvpn/keys/ca.crt

#Server Certificate
cert /etc/openvpn/keys/server.crt

#Server Key and keep this is secret
key /etc/openvpn/keys/server.key

#See the size a dh key in /etc/openvpn/keys/
dh /etc/openvpn/keys/dh1024.pem

#Internal IP will get when already connect
server 192.168.200.0 255.255.255.0

#this line will redirect all traffic through our OpenVPN
push “redirect-gateway def1”

#Provide DNS servers to the client, you can use goolge DNS
push “dhcp-option DNS 8.8.8.8”
push “dhcp-option DNS 8.8.4.4”

#Enable multiple client to connect with same key
duplicate-cn

keepalive 20 60
comp-lzo
persist-key
persist-tun
daemon

#enable log
log-append /var/log/myvpn/openvpn.log

#Log Level
verb 3
Save it.

Create a folder for the log file.

mkdir -p /var/log/myvpn/
touch /var/log/myvpn/openvpn.log

Disable firewalld and SELinux
Step 1 – Disable firewalld

systemctl mask firewalld
systemctl stop firewalld

Step 2 – Disable SELinux

vim /etc/sysconfig/selinux

And change SELINUX to disabled:

SELINUX=disabled

Then reboot the server to apply the change.

Configure Routing and Iptables
Step 1 – Enable iptables

systemctl enable iptables
systemctl start iptables
iptables -F

Step 2 – Add iptables-rule to forward a routing to our openvpn subnet.

iptables -t nat -A POSTROUTING -s 192.168.200.024 -o eth0 -j MASQUERADE
iptables-save > /etc/sysconfig/iptablesvpn

Step 3 – Enable port forwarding.

vim /etc/sysctl.conf

add to the end of the line:

net.ipv4.ip_forward = 1.

Step 4 – Restart network server

systemctl start openvpn@server

Client Setup
To connect to the openvpn server, the client requires a key and certificate that we created already, please download the 3 files from your server using SFTP or SCP :

ca.crt
client.crt
client.key
If you use a Windows Client, then you can use WinSCP to copy the files. Afterwards create a new file called client.ovpn and paste configuration below :

client
dev tun
proto udp

#Server IP and Port
remote 192.168.1.104 1337

resolv-retry infinite
nobind
persist-key
persist-tun
mute-replay-warnings
ca ca.crt
cert client.crt
key client.key
ns-cert-type server
comp-lzo
SCP

And save it.

Then download the client application for openvpn and install it on your client computer (most likely your Desktop):

Windows user

OpenVPN Install.

Mac OS user

tunnelblick.

Linux user.

try networkmanager-openvpn through NetworkManager.

or use terminal

sudo openvpn –config client.ovpn

Install Miner with EthOs with your Mac Osx

 

Install an usb stick with EthOs (1.2.9) on your Mac OS X

Open a Terminal (in /Applications/Utilities/)

Download (and buy) the EthOs from:
https://gpushack.com/collections/gpushack/products/ethos-16gb-digital-download
unpack the file with : xz -d ethos-1.2.9.img.xz or if you don’t have the xz decompressor use
gunzip ethos-1.2.9.img.xz
Nou you have a file called: ethos-1.2.9.img

Insert your flash media USB stick
Run: diskutil list and determine the device node assigned to your flash media (e.g. /dev/disk2)

Run diskutil unmountDisk /dev/disk2 (replace 2 with the disk)

Execute: sudo dd if=/path/to/ethos-1.2.9.img of=/dev/rdisk2 bs=1m (replace /path/to/ethos-1.2.9.img with the path where If you see the error dd: Invalid number `1m’, you are using GNU dd. Use the same command but replace bs=1m with bs=1M.
This take a while… take coffee and a lunch!
Run diskutil eject /dev/disk2 and remove your flash media when the command completes

Now you can boot de server with the USB stick and install the software on the miner…

restore telnet in Mac OSX High Sierra


You can use “nc” to check for (open) ports
This program NetCat is included in Mac OSX High Sierra
Sample:
nc www.server.com 25
if this is not enough you can install telnet from HomeBrew

# install HomeBrew as a regular user (not root)
/usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

# get telnet
brew tap theeternalsw0rd/telnet

# install telnet
brew install telnet

#hoppa:
telnet server.com 25
