Setup Distcc for a VPS

Ragadabing · 2017-09-23 09:49:09

Hi,
I've got a not so much powerful notebook, and quite powerful VPS. So I'd like to reduce the compilation time of (mostly AUR packages) on the notebook using the computing power of my VPS, to which I'm connecting via SSH. I'm a little bit confused by the Arch Wiki page about Distcc. First to clarify if I understood correctly, my notebook will be the master node (because it wants to compile something), and my VPS my only slave node (because it should do all the work).

So my problem is now on how to correctly configure them.

On my notebook I put in the the /etc/makepkg.conf the following lines:

BUILDENV=(distcc color ccache check !sign)
MAKEFLAGS="-j3"
DISTCC_HOSTS="IP_ADDRESS_OF_MY_VPS/3"

But I'm not sure on what to put on the VPS in the /etc/conf.d/distccd. I should put in there the IP address of the master node which gets accepted, but my notebook doesn't has a static one, so what do I put in there instead?

DISTCC_ARGS="--allow ???"

DISTCC_HOSTS & DISTCC_ARGS expect network ranges, not individual ip addresses .

post ip addr from both systems.

I assume the laptop and vps server can ping eachother ?

Yes, they can ping each other, just checked it.

ip addr from notebook:

oops, my reply was a bit to fast ;

DISTCC_ARGS on slaves expects a network range, DISTCC_HOSTS on master doesn't (the notation just looks like a network range).

for the slaves use

DISTCC_ARGS="--allow 192.168.1.0/24"

Ragadabing · 2017-09-23 11:05:39

Hm, that doesn't work. How would 192.168.1.0 on the Slave being resolved to my notebook? Isn't the connection only one-way when I connect with SSH to my VPS from my Notebook?
Or could it be that I need to allow my VPS to access my notebook via SSH too to be able to access it via 192.168.1.0?

Systems that participate in distcc need to have network access to eachother, a ssh connection is not suitable.

Unless your server is accessible through a public ip address, setting up a VPN is probably the easiest way to get both machines in the same network.
