This page is just a collection of small useful (to me anyway) snippets of code/commands that I’ve had to use to get things working. Hopefully others may find some of this stuff useful too. If anything needs explaining then may warrant a short blog post in the future.

Installing .net Framework 3.5 Windows 10

Dism /online /enable-feature /featurename:NetFX3 /All /Source:E:\sources\sxs /LimitAccess

Command Snippets

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --reload

hostnamectl set-hostname

Get IP from ifconfig

ip=$(ifconfig ens33 | grep 'inet ' | awk '{ print substr($2,0) }' | cut -f2 -d:)

ip=$(ifconfig eth1 | grep 'inet addr' | awk '{ print substr($2,6) }')

Vagrant (loop)

(1..3).each do |i|
    config.vm.define "server#{i}" do |svr|
        svr.vm.hostname = "server#{i}" "private_network", ip: "{i}"

Line 1 contains a range (1..3), for each iteration the variable “i” will contain the value of the range.
Line 2 defines the vm to be created in virtualbox, using string interpolation to inject i into the name.
Line 3 defines name be used for the actual vm’s os hostname. Again appending the value of “i”.
Line 4 set a private network for the vm being created and specifies the IP Address and “i”  within the last octet.
