Crypt-fix

Use this script via curl -L -O https://gist.github.com/dragon788/e777ba64d373210e4f6306ad40ee0e80/raw/a86f3d05fb56feb6ef01fc2d61a4feb2fd82b281/crypt-fix.sh and sudo bash ./crypt-fix.sh. You may need to edit the DEVICE variable to reflect your disk and partition layout (this was created on an EFI system using LUKS and LVM). It will prompt you for your disk password once to mount and discover the correct name for the encrypted volume mount and then prompt again to mount with the correct name so that the update-initramfs command succeeds with the appropriate mapping, if this wasn't done you would get a warning and your next boot would still fail.

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

mikequentel

# Source global definitions
if [ -f /etc/bashrc ]; then
  . /etc/bashrc
fi

alias cp='cp -i'
# alias ct='cleartool'
alias h='history'
alias l='ls -hal'
alias mkdir='mkdir -p'

Do I have a web server running?

---

having a web server turned on doesn't necessarily mean you are serving pages on the world wide web. its what allows you to load your own static files (.html, .js etc.) in a browser via http://.

if you're not sure whether or not you have a web server running, no problem! its easy to confirm.

what happens when you visit http://localhost/?
