PV can report progress for large data imports. In this example I will use a large (7 G) install on Ubuntu. First, download PV (http://linux.die.net/man/1/pv)
sudo apt-get install pv
A traditional mysql import may be formatted as:
mysql -u USER -p DATABASE_NAME < DUMP.mysql
but to leverage PV, pass the dump file ,then pipe the mysql command specifying the database with -D flag:
pv DUMP.mysql | mysql -u USER -p -D DATABASE_NAME
Your import will report progress and an ETA 🙂
Lately for a project needed to install opmanager for a specific client. The installation is quite straight forward on a fresh installation of Centos 7 Box. Assuming you already have a linux installaiton file (ended with .bin) file. So here it goes-
Installing OpManager on Linux using Console mode / Silent mode
This is a quick walk-through of the console mode installation of OpManager on a Linux box – an easy thing to do if you are working on a Windows box and want to install on a remote Linux system.
To begin with, make sure you have downloaded the binary for Linux. (https://www.manageengine.com/network-monitoring/download.html)
Steps to install
Step 1: Execute the binary with administrator privileges (sudo) and -i console option.

Let’s Encrypt for cPanel Installation using Installing the cPanel Plugin
Log into your SSH client at root level, then add the Let’s Encrypt repository with the following command:
cd /etc/yum.repos.d/ && wget https://letsencrypt-for-cpanel.com/static/letsencrypt.repo
Next, install the plugin for cPanel with line below and yum:
yum -y install letsencrypt-cpanel
The installation process usually takes about a minute. If all goes well and the installation was successful, a test should run automatically. If it renders similar messages as the example below, you’re good to go:
[SELF-TEST] Can read config ............ SUCCESS.
[SELF-TEST] Can connect to daemon and check licence ............ SUCCESS.
[SELF-TEST] Can connect to Lets Encrypt ............ SUCCESS.
[SELF-TEST] Can talk to WHM API ............ SUCCESS.
[SELF-TEST] Can talk to plugin RPC ............ SUCCESS.
You can log in to your cPanel account and install your first SSL certificate.
Installing a Certificate
Once you’re logged into cPanel, you should see a Let’s Encrypt for cPanel button under Security. Click on it to access your active domains list to install a certificate.

In this tutorial I am going to configure squid acting as transparent proxy what does it means? It means we have no part of configurations on the client end, just to setup squid in transparent proxy mode so it will sits between client and internet. And redirect their port 80 requests to 3128 port which is default squid port. Here the simple steps which you need to perform on squid server.
- CetnOs 6.4 (as squid transparent proxy server), Hostname = pxy.lintut.com
- eth0 : (Connected to Internet) IP = 192.168.1.211/24, Gateway = 192.168.1.1 and DNS = 184.108.40.206
- eth1 : (Connected to LAN) IP = 10.0.0.1/24, and DNS = 220.127.116.11
- Xp Pro SP3 (Client PC for testing). Hostname = xp1.lintut.com IP = 10.0.0.11/8, Gateway = 10.0.0.1(squid Server’s IP) and DNS = 10.0.0.3
Step-1 Installing squid packages.
yum install squid -y
Step-2 Edit squid configuration file ‘/etc/squid/squid.conf’. Continue reading “Squid as Transparent Proxy on CentOs 6.4” »
