Remote Computing

Computations beyond a certain size are usually moved to a remote computing facility, typically accessed using tools such as Secure Shell or Mosh, combined with a terminal multiplexer such as GNU Screen or Tmux. In this scenario it is useful to install a webserver for remote viewing of the html logs.

The standard ~/public_html output directory is configured with the scenario in mind, as the Apache webserver uses this as the default user directory. As this is disabled by default, the module needs to be enabled by editing the relevant configuration file or, in Debian Linux, by using the a2enmod utility:

sudo a2enmod userdir

Similar behaviour can be achieved with the Nginx by configuring a location pattern in the appropriate server block:

location ~ ^/~(.+?)(/.*)?$ {
  alias /home/$1/public_html$2;

Finally, the terminal output can be made to show the http address rather than the local uri by adding the following line to the ~/.nutilsrc configuration file:

outrooturi = 'https://mydomain.tld/~myusername/'
