How to permanently configure static IP Address of Bitnami Backendless Standalone Linux version?
The Bitnami VM comes configured to use DHCP.
The Bitnami FAQ says you can change the IP address using the command below:
An alternative approach is to configure the network manually and assign a static IP address to the virtual machine. For example, if your local network uses IP addresses of the form 192.168.1.X and you know that the IP address 192.168.1.234 is unassigned, manually assign this to the virtual machine by executing the command below at the virtual machine console:
sudo ifconfig eth0 192.168.1.234 netmask 255.255.255.0 up
Unfortunately, the IP Address is only assigned until the server is rebooted. After rebooting the VM, the IP address is dynamically allocated using DHCP.
ifconfig changes the IP Address only during the system runtime.
Depending on your Linux distribution, you've got to change the network setting by editing the related files.
Debian/Ubuntu
$ sudo vi /etc/network/interfaces
Fedora/Centos
$ sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0

I'm trying to set up a virtual machine with CentOS 7 to use it as an Oracle Database Server (I'm new to Linux). I have encountered a problem about the host configuration that as I was reading has to be configured previously.
You see, this is where I collide with my knowledge that I have in windows. I thought it was enough to change the device name like this:
[root#localhost.localdomain ~] # hostname SERVER01
[root#localhost.localdomain ~] # hostname
SERVER01
[root # SERVER01 ~] #
And I do not understand why from windows I can not ping the Linux machine only using its hostname (SERVER01)
The ping request could not find host SERVER01. Check the name and
try again.
I understand that the previous configuration of the host in CentOS 7 that I am asked to install the database server has to do with the fact that I can not ping it using SERVER01. Although I have to clarify that using the IP if I can.
What do I do to make that change in Linux and can ping only using the hostname as it happens in windows?
When you change the hostname in linux you are essentially just telling the OS "this is your name".
In order to reflect that on the network mapping as well, you need to edit the hosts file:
nano /etc/hosts
or if you are a vi fan:
vi /etc/hosts
Note that you will need root access to do this.
In that file you can just extend the localhost mapping to also include your custom hostname SERVER01
127.0.0.1 localhost.localdomain localhost SERVER01
Once you do this, from the same CentOS terminal you can type ping SERVER01 and it should give you a proper ping results.
If you want to be able to ping and access the services on that virtual machine from your Windows OS, then you will need to do the same mapping through the hosts file on your Windows, but this time you will have to use the IP provided to the vm, instead of 127.0.0.1.

Folks,
I have Kali linux running on VM machine..there are 2 interfaces configured on this machine..1 interface is configured as "share with my Mac" and the other interface is configured as "Private to Mac".And i believe "private to Mac" option will allow me to connect my VM linux machine to the local machine.... ifconfig command doesn't show any output. i have manually configured the IP address to both interface by editing vi /etc/network/interfaces and restarted the network services using the command "/etc/init.d/networking restart"...but still ifconfig doesn't give any result....
Actually i want to communicate on port ssh from my local machine to the linux vm machine..since the machines do not communicate each other.i am not able to work anymore..Can someone please have a look in this issue and let me know what changes are required to complete my requirement...
Have you tried sudo ifconfig ? If it doesn't work the problem could be the drivers of your network card. I'm not sure this will works but you can watch this tutorial How to install network card to Kali

I wish to know my current IP address (as the world sees it) via linux command line. I used ifconfig but it doesn't display the same ip address as is displayed on the website ip-details.com.
is there a way to get the current IP address from command line in linux?
thanks in advance
To find your external IP use the following command
$ dig myip.opendns.com #resolver1.opendns.com +short
This would give your IP as seen by a website
dig command is a DNS lookup utility.
DIG (domain information groper) is a flexible tool for interrogating DNS name servers.
It performs DNS lookups and displays the answers that are returned from the name server(s) that were queried
Are you using a VM (or) you are trying ifconfig from machine directly connected to internet ?
If you are trying from a VM it will not show. You have to try at host machine

Scenario: Main Linux Server is Connected to Local Switch Gateway. From Gateway to the network.
Now i can able to get the IP of the Remote Clients/Users who logged into the Server.
Linux Command : *"who -u" (gives me the IP Address of the users IP Address).*
For getting the MAC Address of the same user. I tried the arp -a command, It gave the switch MAC-Address only. I cant able to get the Remote Clients/User MAC Address.
Linux Command : "arp -a" (gives me the MAC Address of the Switch).
How to the MAC Address of the Remote Clients Machines ?
Note : My Client Machines can run on any OS (Windows/Linux/Solaris).
MAC addresses doesn't get routed, so the IP address would have to be of a host on your network. You will have to ping the IP address first and then use arp -a; like
ping <Remote_IP_Address>
arp -a <Remote_IP_Address>

I want to configure my lan interface of the router with 2 IP address.
My router has OpenWRT as firmware
How to edit my openwrt config file inorder to have 2 ip address on the same lan interface?
ifconfig is a quite deprecated tool.
Today we have iproute2 suite which, for many reasons, is much better than ifconfig&co.
For example with iproute2 you don't have to use the "trick" of a virtual interface to have more the one ip address on the same physical interface:
ip addr add IP dev eth0
As you have tagged "linux" in your question, I guess OpenWRT is Linux based.
On Linux, you can do aliases to your eth0 interface. For example, to add an IP to an existing eth0 interface which has already one configured IP, you can do something like:
# ifconfig eth0:1 newIP ... rest of parameters ... (from root)
It would help if you add a sample of your configuration file to the question.
