     17* VPN password update
     18  - Scooter says lab vpn passwords all need to be updated to conform to UCSF password rules.
     19  - Use vpnpassword program on plato to update.
     20
     21* Qt 6 on CentOS 7 presented by Greg
     22  - Qt 6 needs newer compilers and C runtime than CentOS 7 uses.
     23  - Also Qt 6 builds use newer kernel system calls than CentOS 7 offers.
     24  - CentOS 7 end of life is May 2024.
     25  - UCSF Wynton cluster is using CentOS 7.
     26  - Have one ChimeraX download for CentOS 7 with commercial license.
     27  - Can run ChimeraX with Qt 6 on a CentOS 8 virtual machine on top of CentOS 7.
     28  - VMWare has free workstation license.
     29  - Some trouble to setup virtual machine so graphics drivers work.
     30  - Greg tried containers: singularity, docker, flatpak.  None work due to newer kernel system calls used by Qt 6 builds.
     31  - Can update CentOS 7 kernel using ELRepo repository to get newer kernel calls.  But this is probably not acceptable to users who want a standard CentOS 7 distribution.
     32  - When using a container, the container needs the correct system dependent graphics drivers.
     33  - For Wynton, Scooter suggests vis nodes could run Rocky 8 (CentOS 8), but it does raise some problems.
     34  - TomF suggests checking Toolshed update logs to count active CentOS 7 ChimeraX users.  Greg says only Ubuntu linux distro is distinguished in logs.
     35  - TomG will ask PDB (RCSB and PDBe) what Linux OS they use for ChimeraX, ask SBGrid what Linux they support, ask NIH 3D what Linux distro being used.
     36  - Scooter suggests that Greg test virtual machine solution on an actual Centos 7 system.  Greg had tested on a virtual machine CentOS 7.

     38* Chimera web services deprecation notice
     39  - Send notice to chimera-users warning that web services will be turned off in 12-18 months.
     40  - Currently drafted message by Elaine and Zach is fine.
     41  - Zach will send it.
     42  - Scooter disabled multifit Chimera service.  Chimera gui for multifit was removed years ago.
     43
     44* Poster printer
     45  - Scooter will have Epson printer repair person look at poster printer.
     46
     47* VizVault projector
     48  - TomF looking for projector vendor that will allow returns if projector does not work in our room.  Difficult to find.
