Ether Channel Configuration

What is LACP?

This is Standards-based (IEEE 802.3ad) negotiation protocol. Link Aggregation Control Protocol, is used to dynamically build an EtherChannel. There are different modes of LACP.
  • Active: The active end of the group sends out a LACP frame and initiates the negotiation to form the EtherChannel. Both ends could be active and the result would be the same.
  •  Passive: Passive Mode does not initiate the negotiation. It just responds to LACP packets initiated by other end. So if both ends were passive, the EtherChannel would not be formed.

What is PAgP? 

This is Cisco proprietary negotiation protocol. Port Aggregation Protocol is used to achieve the same goal as LACP. PAgP has 2 modes:
  •  Desirable: In this mode, the negotiation will be initiated by sending the special frames to form EtherChannel with the other end.
  • Auto: In this mode, negotiation is not initiated. It only responds to the special frames received for negotiation form the other end. So, if both ends are in Auto mode, EtherChannel would not be formed.
There is basically no difference between the two other than the names of the mode.

One thing to note is that there is no particular command to enable LACP or PAgP on a Cisco router. Instead, the mode names are used.

For example: If you use Desirable mode, then the router understands that you are implementing PAgP and if you use Active mode, the router will understand that you're trying to use LACP. 


Ether Channel Modes
-------------------------------------------------------------------------------------------------
Mode        Protocol                                Description
-------------------------------------------------------------------------------------------------
Auto         |  PAGP  |                  Sets the interface to respond to PAgP negotiation packets, but
                                                   the interface will start negotiations on its own.

Desirable  |  PAGP  |                 Sets the interface to actively attempt to negotiate a PAgP
                                                   connection.

On           | EtherChannel |         Forces the connection to bring all links up without using a
                                                   protocol to negotiate connections. This mode can only connect to
                                                  another device that is also set to on. When using this mode, the
                                                  switch does not negotiate the link using either PAgP or LACP.

Active      |  LACP   |                Sets the interface to actively attempt to negotiate connections
                                                 with other LACP devices.

Passive    |  LACP   |               Sets the interface to respond to LACP data if it receives
                                                 negotiation requests from other systems.

  • sudo yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm 

Installing PHP 7.2 on CentOS 7

  • sudo yum-config-manager --enable remi-php72

Once the repository is enabled install PHP 7.2 and few most common PHP modules:

  •  sudo yum install php php-common php-opcache php-mcrypt php-cli php-gd php-curl php-mysqlnd

Verify the PHP installation, by typing the following command which will print the PHP version: 

  • php -v 

OutPut 
PHP 7.2.9 (cli) (built: Aug 15 2018 09:19:33) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies with Zend OPcache v7.2.9, Copyright (c) 1999-2018, by Zend Technologies

 Installing PHP 7.1 on CentOS 7

Enable the PHP 7.1 repository by typing: 
  • sudo yum-config-manager --enable remi-php71
Install PHP 7.1 and few most common PHP modules:
  • sudo yum install php php-common php-opcache php-mcrypt php-cli php-gd php-curl php-mysql 
  • php -v

  • sudo systemctl restart httpd

 Configuring PHP 7.x to work with Nginx

  • sudo yum install php-fpm
By default PHP FPM will run as user apache on port 9000. We’ll change the user to nginx and switch from TCP socket to Unix socket. To do so edit the lines highlighted in yellow:
  • /etc/php-fpm.d/www.conf
...
user = nginx
...
group = nginx
...
listen = /run/php-fpm/www.sock
...
listen.owner = nginx
listen.group = nginx 

Make sure the /var/lib/php directory has the correct ownership:
  • chown -R root:nginx /var/lib/php
Once you made the changes, enable and start the PHP FPM service: 
  • sudo systemctl enable php-fpm
  • sudo systemctl start php-fpm 
  • sudo systemctl restart nginx

How do I allow Windows 7 users to run only specific applications

How do I allow Windows 7 users to run only Specific applications?

  • The first thing you must do is open the Group Policy Editor. You won't find a menu entry for this tool. Instead you start the tool by clicking the Start menu and then entering the command gpedit.msc. When this tool opens, you will find yourself looking at a dual-paned window that looks deceptively simple to use (Figure A). 

  • Figure A

  • The next step is to navigate to the correct location of the configuration option we want to change. This is to be found in the following path:
    User Configuration | Administrative Templates | System
    When you navigate to that path, you will want to click on the System entry to reveal the available settings in the right pane (Figure B). 

  • Figure B

  • Double-click on the entry for Run Only Specified Windows Applications to open the preferences for this setting. When this is opened (Figure C), you will need to first make sure Enabled is checked. Once you have done that, the Show button will become available.

  • Figure C

     
  • The next step is to click the Show button, which will open a small window where you can enter the allowed applications (Figure D). In this window, you will add, one per line, the executable file name (including extension) for each of the applications you want the users to be allowed to execute. 

  • Figure D

  • After these step just open cmd and type command gpupdate

CentOS 7 SSH key for no password Authentication login with RSA Key

CentOS 7 SSH key for no password Authentication login with RSA Key

 1. ssh-keygen -t rsa
 just simply press enter
if you want to configure password on Rsa file just type a password to protect the other wise leave it blank in my case i am typing password nafees12345

key is generated now copy the id-rsa file in to your pc
next is change mode
2. chmod 700 ~/.ssh 
3. mv ~/.ssh/id_rsa.pub ~/.ssh/authorized_keys

the above command no 3 will change the rsa.pub file to authorized_key this file will used when we try to login via ssh and ssh will match the rsa key from this file now change the mode of file
4. chmod 600 ~/.ssh/authorized_keys 
5. vi /etc/ssh/sshd_config 


 6. systemctl restart sshd

7.Go to official Putty download page, grab the last version of the Putty Windows Installer executable package and install it onto your Windows computer. 

 8.After you have finished installing Putty go to Windows Start, type putty string to search field and open PuTTygen program which you will use it to generate Keys pairs.



Click on load and load the
Now type tha passphrase key which is in my case nafees12345


clik on save private key to save key for putty access
Open putty to left Category menu, select SSH –> Auth, hit the Browse button, search and add your Private Key.
