How to configure a static ip in Linux using Console?

Configuring your Linux machine to run on a static IP is easy. You can do that both from Console and GUI.

This tutorial is to configure a static ip in Linux using Console. Follow following steps :

a) Go to

# cd /etc/sysconfig/network-scripts/

Every network interface will have it’s own interface script files.

For Ex - eth0,eth1,eth2 etc.

b) Edit ifcfg-eth1 interface script file for interface eth1.

Replace the contents of the ifcfg-eth1 file with the parameters below.

# vi ifcfg-eth1

DEVICE=eth1

IPADDR=xxx.xxx.xxx.xxx

NETMASK=255.255.255.0

NETWORK=xxx.xxx.xxx.0

# If you're having problems with gated making xxx.xxx.xxx.0/8

# a martian, you can change this to something else

# (255.255.255.255, for example)

BROADCAST=xxx.xxx.xxx.255

ONBOOT=yes

NAME=loopback

c) Save the file and restart your interface to apply changes.

# ifdown eth1

# ifup eth1

# service network restart

d) That's it :)

Thanks!!!!!!! Enjoy Programming :)

Odoo/OpenERP: one2one relational field example

one2one relational field is deprecated in OpenERP version>5 but you can achieve the same using many2one relational field. You can achieve it in following two ways : 1) using many2one field in both the objects ( http://tutorialopenerp.wordpress.com/2014/04/23/one2one/ ) 2) using inheritance by deligation You can easily find the first solution with little search over internet so let's start with 2nd solution. Scenario : I want to create a one2one relation between two objects of openerp hr.employee and hr.employee.medical.details What I should do i. Add _inherits section in hr_employee class ii. Add field medical_detail_id in hr_employee class class hr_employee(osv.osv): _name = 'hr.employee' _inherits = {' hr.employee.medical.details ': "medical_detail_id"} _inherit = 'hr.employee' _columns = { 'emp_code':fields.char('Employee Code', si

How to draw Dynamic Line or Timeseries Chart in Java using jfreechart library?

Today we are going to write a code to draw a dynamic timeseries-cum-line chart in java. The only difference between simple and dynamic chart is that a dynamic event is used to create a new series and update the graph. In out example we are using timer which automatically calls a funtion after every 1/4 th second and graph is updated with random data. Let's try with the code : Note : I had tried my best to provide complete documentation along with code. If at any time anyone have any doubt or question please post in comments section. DynamicLineAndTimeSeriesChart.java import java.awt.BorderLayout; import java.awt.Color; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.Timer; import javax.swing.JPanel; import org.jfree.chart.ChartFactory; import org.jfree.chart.ChartPanel; import org.jfree.chart.JFreeChart; import org.jfree.chart.axis.ValueAxis; import org.jfree.chart.plot.XYPlot; import

pyodbc.OperationalError: ('08001', '[08001] [Microsoft][ODBC Driver 17 for SQL Server]

Recently, I faced this error in our Docker-Container environment. All the necessary packages were already installed but still, I was facing this clueless error. I search a bit and after an hour and so I found the exact reason and solution for this error. To know more about this error in detail. Please follow this Github thread. https://github.com/mkleehammer/pyodbc/issues/610 https://github.com/mkleehammer/pyodbc/issues/610#issuecomment-587523802 Solution: It's because the server's certificate has too weak a key. In case you are using Linux env directly/not the Docker one. Just edited /etc/ssl/openssl.cnf and change these 2 lines. MinProtocol = TLSv1.0 CipherString = DEFAULT@SECLEVEL=1 In case you are also using a container, please add these three lines to your Docker file. RUN chmod +rwx /etc/ssl/openssl.cnf RUN sed -i ' s/TLSv1.2/TLSv1/g ' /etc/ssl/openssl.cnf RUN sed -i ' s/SECLEVEL=2/SECLEVEL=1/g ' /etc/ssl/openssl.cnf Thanks!! Enjoy Programming! Refer
