Fix: Command not found for whois and dig

Hello,

If you have not installed bind-utils then you wont be able to execute dig commands. basically dig command can be used to DNS information and reverse lookup of a host etc.

To install dig commands , type below commands in your terminal

yum install bind-utils

Then you can try with

dig google.com
dig -x google.com 

If you have executed those commands, you will see sample output as below

and if who is command not working then you have to install jwhois package.

yum install jwhois

and you can test command usage with

whois google.com

Hope it helps you some day!!!!!!!!!!!!!!

List of virtual adapters your Virtual Linux can access

Hello ,

Its me again Raja and this time I came up with one more new post.

I have been through interesting problem.

As many of you know Virtual Box , sometimes even though we enable new adapter and configured IP in conf file it wont comes up. Everything seems fine , we have enabled adapter and configured name and IP for it but still it wont come up.

Simple solution : How many adapters your VM able to access can be easily know by using command

                             ls /sys/class/net

  In my case I have 3 adapters so it will display them

root@fresh:~# ls /sys/class/net
enp0s3  enp0s8  lo
root@fresh:~#

If you come across errors like device not found errors , try to found out how your VM identified the adapters that you have enabled.

Hope it helps.

Thank you.
