Day 10 #90DaysOfDevops

For day 10, i delved into the world of analyzing and managing networks. This appears to be the beginning of the not-so-sweet aspect of linux that i have been expecting.

I had to revisit the chapter twice and some terms more than thrice because i had to configure settings of commands or functions that don’t work unless i configure them, so i spent much time doing that. overall it’s part of the nitty gritty of being a devops engineer.

This chapter i learnt how to:

1. find information on my current network interfaces by using the ifconfig command. The ifconfig command displays the ip address, network mask and broadcast mask.

2. change ip addresses on eth0 by using the ifconfig eth0 command

3. reset ip addresses to a DHCP-assigned address

4. find the nameserver and email server of various websites using the dig command and specifying nameserver with ns and email server with MX. e.g dig hashnode.com ns or dig hashnode.com MX.

Today was quite challenging as my virtual machine/computer wasn’t enabled for some processes such as DHCP, connection to the internet. I scoured the internet for possible answers and got them.

cheers to day 10 and cheers to many more days.
