Install and Configure DHCP Server on CentOS 6 - RHEL 6
 
14:22
DHCP stands for Dynamic Host Configuration Protocol. DHCP is a standardized network protocol used on Internet Protocol networks for dynamically distributing network configuration parameters, such as IP addresses for interfaces and services. DHCP is configured in a server-client model. DHCP server is the one assigning IP Addresses to client computers on the network. Each client is assigned a unique IP Address. DHCP server has a number of IP Addresses available in it’s pool. In this video tutorial, we will see how to install and configure DHCP Server on CentOS 6.x or RHEL 6.x Hope you found it informative and useful. Any questions or comments are welcomed.

Linux Router - Setting up DHCP (1/3) - RHEL 7 / CentOS 7
 
09:44
Read: In this video, I show you how to setup a DHCP server on a CentOS 7 Linux Machine. This is the start of having a computer, running CentOS 7, to be your router and gateway to the internet. This is the first video, and we just touch on getting the DHCP rolling. Notes: If you use debian or anything debian based, I cannot help you. Do not ask for help on those distributions. There are other video resources available. Keep in mind, most of what I do here can be done on those distributions anyway. File locations may vary. Text version: https://www.bromosapien.net/media/index.php/Linux_Router_and_Firewall Prerequisites: -A PC -Two Network cards (One can be built in, and the other can be PCI or PCIe) -Linux You can follow along completely if you use these distributions: --Fedora 20+ --CentOS/RHEL 7 Commands to note: vi -- It's an editor in linux. i for insert, o for a new line, shift+g to go to the end of the file, ESC for command mode. :wq saves your file (zz does too). systemctl restart name --name being the name of the service yum install name ---name being the name of the package systemctl enable/disable -- disables or enables services Files/Folders to note: /etc/dhcp/dhcpd.conf /etc/sysconfig/network-scripts/ifcfg-* IP Scheme format: 10, 172, 192 are private IP's. Use them. Trust me. Interface notes... ens192 is the modem ens224 is the network Dropping pings: -A INPUT -i enp3s0 -p icmp -m icmp --icmp-type 8 -j DROP Other notes: To make sure it works, you may want to isolate your linux box from the network, hook up a cross-over cable between a laptop and your linux box and see if you can get an IP. This is the best way, in my opinion, to make sure DHCP is working properly. ** RHEL 7/CentOS 7 names their network interfaces based on the hardware. This can be changed using biosdevname=0 and net.ifnames=0 on the kernel line at install time. You can also use this when the system is up and ready. You are free to rename the interfaces using udev rules. FAQ: 1. I know my syntax is correct, I have no mistakes, but I cannot get DHCPD to start. It always fails! A. You may have to start all the way over. However, you may want to check for missing semicolons. Typically systemctl status dhcpd -l will tell you what's going on. 2. My computers are not getting IP's set up from my box, what do I do? A. Make sure your stock router is not issuing its own DHCP. The best way to do this, is to log into your router (usually 192.168.0.1). Admin being the username and password being the password by default. Some are admin/admin. Read your documentation for more details. You may ALSO want to give the router an IP address so you can still access it later... it needs to match the scheme you setup. Example of my scheme: 10.100.2.20 :: It's outside my 100-254 range, so it's easy for me to remember. 3. I can ping my own IP given to me from my provider, so this means I'm not secured? A. No, just because you can ping yourself, doesn't mean you're not secure. You're just pinging that modem, pretty much, if you want to think of it that way. 4. Will you ever make a written tutorial for this? I enjoy the visual and explanations, but a written tutorial would be nice too. A. Yes, there is one available at the top of the description.

What are DHCP Options..!!
 
03:05
DHCP servers can configure more than just an IP address. They also provide information about network resources, such as DNS servers and the default gateway. You can apply DHCP options at the server, scope, user, and vendor levels. An option code identifies the DHCP options, and most option codes come from the Request for Comments (RFC) documentation found on the Internet Engineering Task Force (IETF) website.

DHCP RELAY - CENTOS 7
 
13:47
The DHCP Relay Agent (dhcrelay) enables the relay of DHCP and BOOTP requests from a subnet with no DHCP server on it to one or more DHCP servers on other subnets. When looking for DHCP traffic on Wireshark, keep in mind to use bootp instead of dhcp that I used on the video, this was the reason why the video took long.

Hi friends today's I will show to you how to install openvpn on centos 6.4 step by step. Openvpn installation is very complex but in this video tutorial everyone can install and configure openvpn very easy. Following the step: This video tutorial divided in two parts. First part is server side installation and 2 part is client side installation Centos 6.4: Wan interface card = eth0 = 192.168.10.120 Lan interface card = eth1 = 192.168.0.20 Window client: Wan interface card = 192.168.10.116 Lan interface card ip address = 192.168.0.244 Login server as root user ----------------------------------- Step 1 - First command you can put yum install gcc make rpm-build autoconf.noarch zlib-devel pam-devel openssl-devel --y Step 2 - Second you put confirm wget install on centos Yum install wget --y Step 3 - Now can download LZO RPM and Configure RPMForge Repo wget http://openvpn.net/release/lzo-1.08-4.rf.src.rpm Step 4 - Now add correct repo for your server CentOS 6 32-bit (x86): wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-1.el6.rf.i686.rpm CentOS 6 64-bit (x86_64): wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm step 5 - Then build the rpm package using this command rpmbuild --rebuild lzo-1.08-4.rf.src.rpm rpm -Uvh lzo-*.rpm rpm -Uvh rpmforge-release* step 6 - Installing OpenVPN yum install openvpn --y step 7- Copy the easy-rsa folder to /etc/openvpn/, use this command cp -R /usr/share/doc/openvpn-2.2.2/easy-rsa/ /etc/openvpn/ Step 7 -- Now edit it Vi /etc/openvpn/easy-rsa/2.0/vars export KEY_CONFIG='$EASY_RSA/whichopensslcnf $EASY_RSA' replace it with export KEY_CONFIG=/etc/openvpn/easy-rsa/2.0/openssl-1.0.0.cnf Step 8 -- Create the certificate using these commands: cd /etc/openvpn/easy-rsa/2.0 chmod 755 * source ./vars ./vars ./clean-all Step 9 -- It's time to build necessary CA file: ./build-ca Step 10 -- Time to build Key Server: ./build-key-server server Step 11 -- Now issue command below to build Diffie Hellman: ./build-dh Step 12 -- Create OpenVPN config file: Vi /etc/openvpn/server.conf port 1194 #- port proto udp #- protocol dev tun tun-mtu 1500 tun-mtu-extra 32 mssfix 1450 reneg-sec 0 ca /etc/openvpn/easy-rsa/2.0/keys/ca.crt cert /etc/openvpn/easy-rsa/2.0/keys/server.crt key /etc/openvpn/easy-rsa/2.0/keys/server.key dh /etc/openvpn/easy-rsa/2.0/keys/dh1024.pem plugin /usr/share/openvpn/plugin/lib/openvpn-auth-pam.so /etc/pam.d/login #- Comment this line if you are using FreeRADIUS #plugin /etc/openvpn/radiusplugin.so /etc/openvpn/radiusplugin.cnf #- Uncomment this line if you are using FreeRADIUS client-cert-not-required username-as-common-name server 192.168.0.0 255.255.255.0 push "redirect-gateway def1" push "dhcp-option DNS 8.8.8.8" push "dhcp-option DNS 8.8.4.4" keepalive 5 30 comp-lzo persist-key persist-tun status 1194.log verb 3 Step 14 -- Lets start OpenVPN service on your server for the very first time: service openvpn start Step 15 -- Lets start OpenVPN service on startup chkconfig openvpn on Step 16 -- You'll also need to enable IP forwarding Vi /etc/sysctl.conf replace 0 with 1 in this line: net.ipv4.ip_forward = 1 Step 17 -- Issue this command to load the change: sysctl --p Step 18 -- Create new Linux username which can also be used to login to the VPN: useradd username -s /bin/false Then also create its password: passwd username Step 19 -- Now route some iptables Xen and KVM users use: iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE special for OpenVZ use these two instead: iptables -t nat -A POSTROUTING -o venet0 -j SNAT --to-source 123.123.123.123 and iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j SNAT --to-source 123.123.123.123 Step 20 -- Now save that iptables and restart rules Service iptables save Service iptables restart if you learn more linux tutorial than visit my official website http://www.broexperts.com/

Linux Router - Setting up IPTABLES and NAT (2/3) - RHEL 7 / CentOS 7
 
06:34
Read: In this video, I show you how to setup iptables/firewall/NAT on your DHCP server. This is the second video of having a CentOS 7 Linux box running as a DHCP server, gateway, and router of any given network. We touch on iptables and how to set it up with various commands. FirewallD is a frontend to iptables. Keep in mind that we disable it in this tutorial. % systemctl disable firewalld % systemctl stop firewalld Written version: https://www.bromosapien.net/media/index.php/Linux_Router_and_Firewall Notes: If you use debian or anything debian based, I cannot help you. Do not ask for help on those distributions. There are other video resources available. Keep in mind, most of what I do here can be done on those distributions anyway. File locations may vary. Prerequisites: -You followed the first video -DHCP is running correctly (make sure you have tested this) You can follow along completely if you use these distributions: --Fedora 20+ --CentOS 7 IPTables syntax: -A Append FORWARD/INPUT/POSTROUTING/PREROUTING: Tables -i input interface -o output interface -p protocol -m match -j command (ACCEPT/DENY/DROP) Interface notes... ens192 is the modem ens224 is the network Dropping pings: -A INPUT -i enp3s0 -p icmp -m icmp --icmp-type 8 -j DROP Commands to note: vi -- It's an editor in linux. i for insert, o for a new line, shift+g to go to the end of the file, ESC for command mode. :wq saves your file (zz does too). systemctl restart name - restarts service iptables -t (table) -A --The command to create iptables rules. (table) being nat or filter. Files/Folders to note: /etc/sysconfig/iptables -- The file where iptables information is stored. Example: https://www.bromosapien.net/media/index.php/Linux_Router_and_Firewall#iptables:_The_Linux_Firewall Useful link: http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch14_:_Linux_Firewalls_Using_iptables FAQ: 1. Can I forward more than one port to any IP's through iptables? A. Yes you can, just make sure you use PREROUTING and FORWARD rules respectively. 2. In your other videos, you dropped pinging from the outside. Why didn't you do it this time? A. To be honest, I forgot. It is recommended to turn off pings from the outside on the INPUT chain.

Linux - Setting up a DHCP Server (CentOS 5/6 LEGACY) (Video 1 of 4 for setting up Linux Router)
 
14:34
THIS IS NOW LEGACY... PLEASE CONSIDER USING CENTOS 7 Read: In this video, I show you how to setup a DHCP server on a linux machine. This is the start of having a computer, running linux, to be your router and gateway to the internet. This is the first video, and we just touch on getting the DHCP rolling. Thank you, Shane. Notes: If you use debian or anything debian based, I cannot help you yet. Do not ask for help on those distributions. I will have something for you soon. Text version: https://www.bromosapien.net/media/index.php/Linux_Router_and_Firewall Prerequisites: -A PC -Two Network cards (One can be built in, and the other can be PCI or PCIe) -A linux operating system You can follow along completely if you use these distributions: --Fedora --CentOS 5/6 (6 with some file placement modification) NOTE: Edit the /etc/sysctl.conf file and find the line that says net.ipv4.ip_forward. Set it to 1. This will make it work! http://www.youtube.com/watch?v=ES53ZpVnEpQ Commands to note: vi -- It's an editor in linux. i for insert, o for a new line, shift+g to go to the end of the file, ESC for command mode. :wq saves your file (zz does too). nano -- Another editor in linux, much easier to use. pico --Alternative to nano if not available. services name restart --name being the name of the service yum install name ---name being the name of the package chkconfig -- Changes runlevels of services (Example of chkconfig: chkconfig --list dhcpd) Files/Folders to note: https://www.bromosapien.net/media/index.php/Linux_Router_and_Firewall#Setting_up_DHCP IP Scheme format: 10, 172, 192 are private IP's. Use them. Trust me. Other notes: To make sure it works, you may want to isolate your linux box from the network, hook up a cross-over cable between a laptop and your linux box and see if you can get an IP. This is the best way, in my opinion, to make sure DHCP is working properly. FAQ: 1. I know my syntax is correct, I have no mistakes, but I cannot get DHCPD to start. It always fails! A. You may have to start all the way over. Sometimes that's the best way. Make sure to check for colons. 2. My computers are not getting IP's set up from my box, what do I do? A. Make sure your stock router is not issuing its own DHCP. The best way to do this, is to log into your router (usually 192.168.0.1). Admin being the username and password being the password by default. Some are admin/admin. Read your documentation for more details. You may ALSO want to give the router an IP address so you can still access it later... it needs to match the scheme you setup. Example of my scheme: 10.240.100.20 :: It's outside my 100-254 range, so it's easy for me to remember. 3. I can ping my own IP given to me from my provider, so this means I'm not secured? A. No, just because you can ping yourself, doesn't mean you're not secured. You're just pinging that modem, pretty much, if you want to think of it that way. 4. Will you ever make a written tutorial for this? I enjoy the visual and explanations, but a written tutorial would be nice too. A. In the future I will. I have plans, but when I will type it all up is a decision I do not have yet. However, anyone can take what I have done in these tutorials and write it all out and make a tutorial easy off of it. If you do, make sure you leave a comment and I'll be sure to put it in this description! 5. For some reason, no one on the network can connect to the internet. What happened? A. In the video, I forgot to explain that you need to edit /etc/sysctl.conf and change the ip forwarding to 1. You can watch here to get the idea: http://www.youtube.com/watch?v=ES53ZpVnEpQ

How to configure DHCP Server in Centos 7 , Redhat 7 , Fedora ( Complete Server & client ) https://youtu.be/NIcVO_F0YTg ############################################### What is DHCP Server ? Dynamic Host Configuration Protocol (DHCP) is a network protocol that is used to enable host computers to be automatically assigned IP addresses and related network configurations from a server. The IP address assigned by a DHCP server to DHCP client is on a “lease”, the lease time normally varies depending on how long a client computer is likely to require the connection or DHCP configuration. How Does DHCP Work? The following is a quick description of how DHCP actually works: Once a client (that is configured to use DHCP) and connected to a network boots up, it sends a DHCPDISCOVER packet to the DHCP server. When the DHCP server receives the DHCPDISCOVER request packet, it replies with a DHCPOFFER packet. Then the client gets the DHCPOFFER packet, and it sends a DHCPREQUEST packet to the server showing it is ready to receive the network configuration information provided in the DHCPOFFER packet. Finally, after the DHCP server receives the DHCPREQUEST packet from the client, it sends the DHCPACK packet showing that the client is now permitted to use the IP address assigned to it. In this article, we will show you how to setup a DHCP server in Ubuntu/Debian Linux, and we will run all the commands with the sudo command to gain root user privileges. Testing Environment Setup We are going to use following testing environment for this setup. DHCP Server - Ubuntu 18.04 DHCP Clients - Ubuntu 18.04 and Windows 10 source - www.techmint,com ############################# follow us on facebook :- https://www.facebook.com/AndroidandTechSolutions/ Blog Link :- https://linuxtechsolutions.blogspot.in/
