KeyShort Description


My work computer cannot ssh into lsst-dev via wired ethernet

Russell Owen



User cannot log in to lsst-dev via wired connection at UW.

The user's IP was blocked by NCSA Security because it was detected attempting brute force ssh scans. The IP was in use by another device at the time. The block has since expired and the incident reported to UW security. Culprit was someone else with a raspi

Change Management

This process primarily targets requests that can be handled with current level of effort (LOE) resources.  This process is also designed to detect and redirect items to the EVMS process if they exceed LOE resources.

Successful changes proceed through 5 stages: 


Business Case & T/CAM ConcurrenceCheck that the submitter has stated a plausible business case and the relevant T/CAM agrees
2FeasibilityIs the change well-formulated, address a project need and
3PlanningA detailed implementation plan is created which takes into account impacts, resource needs, testing and verification.
4InsertionThe plan is executed to implement the change.
5AssessmentVerification of successful change, issues analysis, documentation and close-out.

The members of the Infrastructure Working group have asked that NCSA set a 1 TB/user quota for home directories

FeasibilityPaul DomagalaMajor01/Feb/18

A complementary RFC has been filed: RFC-443, Re-enable per user quotas in home directories

NCSA has yet to discuss this.


DM developers need a build/test environment that supports docker containers


Joshua HoblittMinor02/Nov/17Determining exact needs and if current capabilities are adequate

Configure slurm to accept jobs to use only partial nodes

Discussion in several infrastructure & PDAC meetings. Fritz Mueller has the action item of needs-gathering. Waiting for feedback.

Heard on the Street This Week, but no Ticket Filed

  • New

  • Previous

    • It was suggested that per-user storage usage for each shared fileset be made available.  Preferably readable by any DM member.

    • Several users expressed a desire to have the Intel compiler suite (icc) available on last-dev
    • Increase ssh idle session timeout, which is currently 1 hr. (John Parejko via Slack) 
    • Suggestion to deploy kubernetes on PDAC, it is assumed that this is being handled through the rolling-wave (EVMS) process
    • Tools for parallel programming in batch computing environment (gnu parallel and others)

Change Process Notes

  • Paul has contacted corresponding T/CAMs to understand business need, obtain concurrence & document in each LDMCR
  • Change process is being exercised, refined and socialized with T/CAMs as well as submitters

Problem Management

A problem registry has been begun here to analyze incidents in an effort to identify root cause, frequency and severity.
