hostname <name> will only set the hostname temporarily (until the next restart). Unlike older Redhat/CentOS peers, editing /etc/sysconfig/network and adding a 'HOSTNAME=' directive is ineffective. sysctl kernel.hostname=NEW_HOSTNAME is also only temporary. This is because the hostname is now stored in /etc/hostname.

Every port increases the threat surface and while many if not most of the services that run on these ports are frequently refreshed to keep them secure, they are vulnerable to a potential attack. Devopera machines try to minimise the number of open ports, but that does not mean you're in any way restricted in the kind of connections you can make to services on your machine.

How much RAM it has
How many process cores it has
What kind of filesystem it uses
If you change the configuration of a devopera VM or server build, such as adding more cores or more RAM modules, you might like to refresh the config on your server, or have us do it for you.</div> </div> </div>

Devopera exists because we wanted the freedom to move our website from one host to another with as little fuss as possible. Previously that involved having to rebuild the server, a 2-day job that always resulted in our forgetting to do something. That meant that when we deployed the site, some small facet of it stopped working, which we had to hope would show up in our nightly test suite.
That's idea behind our offering low-cost server builds for a wide array of applications and... <a href="node/41.html" class="views-more-link">+ read more</a></div> </div> </div>
