Adding Linux extended nodes to Qmaster from Ubuntu machines
I realize this is both a complicated question and for some might be seen as a really easy question. I'm hoping for more the latter!
I have a Mac Mini hooked up to a network switch and I plug in my MacBook to set up a very basic cluster through Qmaster. It's the only way i can get jobs done in Compressor, neither of these machines have the specs suggested to really run Final Cut Studio at all, but this is a church and we just appreciate what we have.
In that same spirit, we have an old Dell PowerEdge 700 server I put Ubuntu Studio on running at 256 megs ram and about 2.8 Ghz. A Dell Inspiron 8200 laptop at 1.8 GHZ with 512 ram, and 4 Dell Optiplex with 256 RAM at 1GHZ. All old equipment I realize, but from what I've read it sounds like one can use these in Apple Qmaster as long as they are Unix based. So I've been installing Ubuntu on them (I'm a Linux newbie and the other distros are a pain to install on these machines.)
From what I understand, you put a UNIX system (like Ubuntu) on these, setup something like OpenSSH, and of course I have them plugged into the network switch with my macs.
The macs see each other and can create a cluster.
I setup a Linux box and it could see the mac through the terminal.
But the mac doesn't see the Linux box through terminal.
(Of course I'm new to terminal too.)
I opened up everything on the system preferences side for the mac for sharing services, no firewall setup, ect. I have a feeling there are a multitude of SSH things I have to set up on mac and linux that I just am unaware of.
I go to system preferences _ qmaster _ and try to set up extended nodes with the Mac Mini as an intermediary node (before anyone posts it, yes I've studied the Qmaster manual laboriously.) Where you type in hostname, username, and password, I've been typing in "ubuntustudio" as my hostname because that's what I set it up as when installing. I also set that as username. But every example I see posted lists the username with something like a domain name after it. I think maybe I'm not typing the hostname correctly or something, but I can't find any documentation on naming conventions for something like this.
Sorry if I sound like a newbie, on some of this I am. But our pc techs don't cover the linux machines under our contract, I'm sure Apple would charge me a ton if they were willing to help with this at all, and every support article I have found vaguely mentions that you CAN use SSH to add non-macs to the cluster, but just takes it as a given that you'll know exactly how to input the hostname and that it will work and all your setting will be perfect.
I just think with 6 machines running over 1ghz, collectively they could be a descent set of nodes and it just seems best practice to repurpose old equipment to death before buying new.
Thanks for your time
