Agenda Items
Machines connected to Ceph need to be updated and brought into Salt management
- NFS gateway - RT#1153244
- Samba (ubuntu1804-smb.cs)
- backup.cs (or whatever it is called now)
- All above items will be address for next DFSc meeting.
related - were all production systems updated and rebooted at the end of the Winter term?
- all general-use system had "apt-get update", "apt-get dist-upgrade" run on them.
- should they have had a salt high-state applied to issue appropriate ceph package selection.
- would be good to have automated check for upgrades being done that can run first monday of January, May and September.
disposition of older servers and plans for their future - See RT#1151451
- As it says in the RT items summary: "Any re-purposing of these systems is on hold until Fall 2021 term."
Cups service is out of date
- Clayton points out that linux cups client needs "shim" to pass kerberos ticket to windows print spooler. Not obvious.
- See about installing new cups server. (Dave will setup a project plan)
linux.cs -> ubuntu2004.cs? Scheduled to happen May 1st.
- Happened once management dealt with IST firewalling.
- now that people know about VPN requirements there has been few (no?) complaints.
- IST requires password only authentication to end mid Novemenber 2021.
- CSCF Infrastrcuture group wants password only authentication to end by start of Fall term
- all service changes should happen between terms not in the middle.
- Nick points out we need to tell Profs and Instructors ASAP so they can update course content.
- Dave wants user documentation created regarding remote access to our two domain
- it needs to contain at least a minimum links to IST documentation on VPN, DUO, ssh-key management, rdp
- need CSCF to promote user docs.
- many questions about interoperability of DUO, our domain service, netgroups and resource access.
- much speculation without technical details.
- need a table of CS services and resources indicating what identity and resource mechanisms they require.
Please do not squelch members of a ticket on responses
- we have firm requests from some Professors (Martin Karsten being one example) that DON'T want to see every ticket comment.
Nick: What is the recommended approach for users to send out emails automatically, ex. in a cronjob or script?
- missed the case where a "user" runs a "script/program" that emails out a form letter to a list of users.
- note that CS will not be offering any smtp service, people will need to setup their email client to send messages via the IST selected campus smtp service.
Devon: Is it possible for course accounts to have access to Vault?
- ISA (Barb) wants shared volumes.
- Nick would like Devon to include him on the ticket.
- Dave asks, "Is there still a reason why the course accounts need to stay in the TEACHING domain?"
jupyterhub.cs kvm host (deferred till Fraser is here).
- Lori speculated about leveraging datasci systems. (GPU needed.)
