An instruction: how to get 2 .local domains work with 1 dynamic IP server
- 2 Wi-Fi networks
- Server machine on Ubuntu 16.04.3 LTS “xenial” with two web-services on 0.0.0.0:80
- Consumer laptop with OS X
- domain1.local, domain2.local associated with the web-services even though IPs are dynamical.
- when two laptops are in the same network (doesn’t matter which one) – Consumer should be able to find Server’s web-services.
On Server machine only.
- Install Avahi (actually, already installed)
- Configure the main domain with Avahi.
In
/etc/avahi/avahi-daemon.confuncomment and edit these two lines:
[server]
host-name=domain1
domain-name=local
and run sudo service avahi-daemon restart
2. Install avahi-aliases
mkdir temp && cd temp
wget https://github.com/hmalphettes/avahi-aliases/archive/master.zip
unzip master.zip
cd avahi-aliases-master/
sudo ./install.sh
cd .. && gvfs-trash temp- Configure avahi-aliases to start when avahi-daemon is started. Create a file:
/etc/init.d/avahi-publish-aliases:
#!/bin/sh
# kFreeBSD do not accept scripts as interpreters, using #!/bin/sh and sourcing.
if [ true != "$INIT_D_SCRIPT_SOURCED" ] ; then
set "$0" "$@"; INIT_D_SCRIPT_SOURCED=true . /lib/init/init-d-script
fi

DAEMON=/usr/bin/avahi-publish-aliasesAnd make it run automatically:
sudo update-rc.d avahi-publish-aliases default
-
Configure a second domain:
sudo avahi-add-alias domain2.local -
remove the alias when it’s not needed anymore:
sudo avahi-remove-alias domain2.local
