Create a user specific host file

User specific host file wrapper

$HOSTALIASES no longer works with glibc (https://bugs.launchpad.net/debian/+source/glibc/+bug/1483187)

For my project, I needed to create a user specifc hosts file.

First clone this repo - https://github.com/figiel/hosts.git

################ README #####################################

hosts - wrapper for libc which provides defining host aliases in a per-user file

note:

 - if your libc does support it you may want to set HOSTALIASES instead of
   using this wrapper, see gethostbyname(3).

compilation:

$ git clone https://github.com/figiel/hosts.git
$ cd hosts
$ make

installation:

$ mkdir ~/bin
$ cp libhostspriv.so ~/bin
$ echo 'export LD_PRELOAD=~/bin/libhostspriv.so' >> ~/.bashrc
$ logout

usage:

$ echo "127.0.0.1 new_name" >> ~/.hosts
$ nc -vz new_name 80

For me it works on Chromium and Firefox.

echo "export LD_PRELOAD=/home/chris/Development/hosts/libhostspriv.so {firefox|brave-browser}" >> ~/.bashrc

Set at the system level - 

cp libhostspriv.so

export LD_PRELOAD=/usr/local/lib/libhostspriv.so
