Next week I’ll be traveling to the Switch Las Vegas aka “SuperNAP” or “NAP7” data centers for the implementation/deployment of multiple technologies (Cisco, Nutanix, VMware, Rubrik, etc). As part of the planning & technical design tasks, I noticed I’ll have to bootstrap a four(4) node Rubrik, for which I’ll need the following:
Rubrik uses multicast DNS (mDNS) for node-to-node discovery and to initiate system set up. The computer that is used to perform the system set up (System Setup UI computer) must be connected to the same layer-2 segment as the Rubrik nodes. The System Setup UI computer also must have a supported web browser and specific
mDNS software.The System Setup UI computer can be a server, desktop, laptop, or virtual machine.
The System Setup UI computer must have the following:– Latest version of Google Chrome web browser
Rubrik CDM Install and Upgrade Guide, Version 5.0
– Bonjour Print Services software
– IPv6 support enabled
Since my main laptop runs Arch Linux and I’m not carrying a Mac, which includes the Bonjour Services out-of-the-box, I figured that Avahi was my go-to for this task. So I did a quick search and found out that (as always with Arch Linux), the setup for this was pretty straight-forward and clearly explained in the Arch Wiki. Here it goes:
- Install the required packages:
$ pacman -S avahi nss-mdns gtk3 python-dbus python-gobject- Enable the Avahi daemon in order to make it persistent after reboot:
$ systemctl enable avahi-daemon.service- Start the DBus (if not already running) & Avahi daemons:
$ systemctl start dbus.service$ systemctl start avahi-daemon.service- Edit the
nss –mdns configuration file located on “/etc/nsswitch.conf” and change thehosts line to include “mdns4_minimal [NOTFOUND=return]” before resolve anddns , and include the “mdns4” module at the end (optional):
hosts: … mdns4_minimal [NOTFOUND=return] resolve [!UNAVAIL=return] dns … mdns4
After this, you can use the utilities that come included with Avahi (avahi-browse, avahi-discover, avahi-resolve, etc.) or the Avahi Zeroconf Browser utilities (
Examples:
$ bssh$ avahi-browse --all --ignore-local --resolve --terminate$ avahi-resolve -n device-hostname.local$ ssh user@device-hostname.localAdditional considerations:
Make sure you open UDP port 5353 if you’re using a firewall.
