This is the sudo room gateway. It is located in the sudo room server "room".

  • External hostname: room.sudoroom.org
  • Internal hostname (mDNS): meshbuild.local
  • Internal IP (static): 192.168.42.1
  • ssh port: 60643

It's a Dell SC1425 with:

  • Dual 2.8 Ghz Xeon dual-core processors
  • 6 GB ram
  • 750 GB harddrive.

It runs the following services:

iptables

iptables handles port forwarding and masquerading (NAT). The configuration file is:

/etc/iptables.rules

To change this, use normal iptables commands to modify the iptables configuration and save it using:

sudo iptables-save > /etc/iptables.rules

dnsmasq

dnsmasq handles DNS only. It has some entries for the .sudo domain, such as stuff.sudo in the config file:

/etc/dnsmasq.conf

Look for the line:

 address=/stuff.sudo/192.168.42.1

dhcpd

dhcpd is our dhcp server. The config file is:

 /etc/dhcp/dhcpd.conf

web server

nginx is the web server and reverse proxy. It has a few virtual hosts.

default (e.g: http://room.sudoroom.org)

The only thing currently on here is http://room.sudoroom.org/wakemesh.php which lets people remotely boot the sudo mesh build server.

stuff.sudo (internal only)

Our inventory tracking and labelling system. It prints labels on the Brother QL-570 thermal label printer located next to the Type A Machines 3D printer.
