Baseline

1. Dont be a dick.

3. The core goal of the Skynet cluster is to provide services for the society.
   • These are the more visible services like the linux host/gitlab/nextcloud/....
   • It also includes training for anyone who wants to get more hands on, both administration/hardware.
   • Its not your fiefdom, everything must improve it for others, even if it takes you out of your comfort zone.

Renew Domains

We have two domains, both with Blacknight.
skynet.ie is sponsored to us.
ulcompsoc.ie we have to pay for, renew for two years but check yearly.

Inform ITD that servers are up-to-date and patched

Part of the agreement with ITD is to show them every semester that the server are patched and up to date.

Regular Events

Email

I generally check all the email accounts for new mail once a day or so. There is a good chunk of spam but we do get a fair few mails from alumni trying to reactivate accounts.

Reactivate old accounts

Alumni regularly get in contact to re-activate their skynet accounts.
Be polite and respectful when dealing with them.

Much of this process is covered by renew and recovery however more documentation needs to be added on how to verify users.

Summary

This has been mostly a managerial role, involving organisation and mentorship.
The role looks really good on a CV/LinkedIn.

The roles that Skynet has played over the years has changed dramatically (as outlined in the old history).
One of the main draws for it was the email and cloud storage.
At one point it employed 5 admins, each in charge of their own servers.
Now in this era of DevOps each admin can do so much more while also requiring more diverse knowledge.
This change is exciting, stressful and rewarding.
