− | == Current Projects ==
| |
− | This is the list we will work from in addition to service requests.
| |
− | * Proposal to update our task process: [[Sysadmin/Task_Process]]
| |
− | * Possibly: update CentOS on Pollock and Bronte
| |
− | * Mailing list archives are gone
| |
− | * Graceful shutdown during outage
| |
− | * Web logins
| |
− | * Reinstall OS's on Lovelace and Hamilton machines
| |
− | ** Hamilton: installed, can ssh, so can do whatever else we need
| |
− | ** Lovelace machine: still no Internet
| |
− | * shinken: web is back, need to check status
| |
− | * layout node outside machine room - Eli interested
| |
− | * layout: make different node the head node?
| |
− | * passwords
| |
− | * email to users (automated)
| |
− | * check Lovelace DNS file - check what machines we have vs. what's in the DNS file?
| |
− | * check backup statuses of machines, see the wiki page on this - also backup.cs.e.e (indiana?)
| |
− | * Password auditing script
| |
− | * FIFO for requests rather than ad-hoc
| |
− | * Accounting for hours logged
| |

− | * 159.28.23.26 is a ghost machine - it responds to ping and purportedly exists, but we are unsure where it is or what it is. - ping -f - Eli looking into it in the context of al-salam | + | * [[Sysadmin:CS-ITS Interoperability|Working with ITS]] |
− | * Power map additions and updates
| + | * [[Sysadmin:Recurring spending | Recurring spending ]] |
− | * nbgrader - setup continues
| + | * [[Sysadmin:SlackAndGitLab | Slack and GitLab integration]] |
− | * indiana config | |
− | * Hadoop on Whedon - Vitalii and Adam (stuck on ?) - talk to Ajit | |
