One of the major problems we are running into with devops is the lack of knowledge that devs have about networking. Before there were system and network support teams that could help, but when items are deployed into a "cloud", all bets are off.

Here are some common questions I ask about networking.

What is the difference between a vlan and subnet?

What is a broadcast domain?

What is the difference between icmp, tcp and udp?

Explain how a tcp session is set up?

How are tcp options negotiated and selected?

How would you use tcpdump to determine if one remote host was making a connection to your server?

Link which reroutes to Computefreely.org for Linux for beginners is now not available.

Any linux tutorials in particular that you are on the lookout?

Do you want input/suggestions or are you treating this as read only?

The link to Satck vs heap is dead.

Need to add under Networking

http://blog.packagecloud.io/eng/2016/06/22/monitoring-tuning-linux-networking-stack-receiving-data/#general-advice-on-monitoring-and-tuning-the-linux-networking-stack

Need to add the following URL's

• Make API calls with

  https://docs.angularjs.org/api/ngResource

• For Routing use

https://github.com/angular-ui/ui-router/wiki/URL-Routing

https://github.com/Leo-G/DevopsWiki/wiki/How-Linux-CPU-Usage-Time-and-Percentage-is-calculated

Formula
Total CPU Idle time since boot = idle + iowait
Total CPU usage time since boot = Total CPU time since boot - Total CPU Idle time since boot

IDLE=${CPU[3]} # Just the idle CPU time.
let "DIFF_USAGE=(1000*($DIFF_TOTAL-$DIFF_IDLE)/$DIFF_TOTAL+5)/10"

Where is the IO_WAIT not in Total_CPU_Idel_Time?
What is the meaning "+5" ?

Hello,

Is there a specific reason why you are using this kind of link style?

Vim Cheat Sheet

http://michael.peopleofhonoronly.com/vim/

If not, I would suggest using something like this:

Vim Cheat Sheet

It would save a lot of scrolling down and deliver more content at same time. If you accept this suggestion, I could change to the new styling for you.

Anyway, kind regards.
