Enter key (at right) enter: means to type the characters that follow the
space after : & then press Enter It is possible to connect to devices on
the network using the internet or using the local network. To connect
using the internet: 1. Enter ssh systemname@machinename.hacdc.org (i.e.,
ssh renderadmin@jobs.hascdc.org) 2. At Password: enter standard password
To connect using the HacDC network: 1. Enter ssh
systemname@machinename.local (i.e., ssh renderadmin@jobs.local) 2. If
the system asks Are you sure you want to continue connecting (yes/no)?
enter: yes 3. At Password: enter standard password To check if it is
possible to communicate with a device: 1. Open a MATE terminal (if not
already present; see Documentation-Tabletop_computers) 2. Enter ping
machinename.hacdc.org or ping machinename.local (i.e., ping jobs.local)
3. If it responds \## bytes from \###... it is communicating 4. To stop
pinging type Ctrl C To determine the path to the address the computer is
connected to: 1. Enter mtr address (i.e., mtr jobs.hacdc.org) 2. When
finished click on Quit If the network will not connect: 1. Try using the
other connection method (.local if .hacdc.org doesn't work or vice
versa) 2. Check if it is possible to communicate by using ping (see
above) 3. If it is not communicating stop here & get help 4. Enter mtr
address (i.e., mtr jobs.hacdc.org) 5. Look at the column labeled Loss;
if any of the values are close to 100% that could be the problem 6.
Click on Quit 7. If there was a problem with the path restart the
computer & hope it uses a different path this time Components of the
network: Renderadmin computer (large computer at left under table below
clock) - for converting .escad files to .stl files for 3D printing
etc. - machine name=jobs, system name=renderadmin 3D printer computer
