- DNS
- What DNS domain will these hosts be in? nrao.edu? remote-institution.site? other?
- Will this vary depending on site?
- DHCP
- SMTP
- NTP or chrony
- NFS
- Directory ServerLDAP?
- NIS? Probably not. RHEL9 will not support NIS.
- OpenLDAP
- 389 Directory Server? (previously Fedora Directory Server)
- Identity Management
- FreeIPA
- How do we handle accounts? I think we will want accounts on at least the head node. The execution nodes could run everything as nobody or as real users. If we want real users on the execute hosts then we should use a directory service which should probably be LDAP. No sense in teaching folks how to use NIS anymore.
- remote institution accounts only?
- 2022-10-26 krowe: RHEL8 and later don't come with OpenLDAP anymore. Red Hat wants you to use either their 389DS or IDM or RHDS or some other thing that gets them money. It's all very confusing
- ssh
- rsync (nraorsync_plugin.py)?
- NAT so the nodes can download/upload data?
- TFTP (for OSes and switch)
- condor (port 9618) https://htcondor-wiki.cs.wisc.edu/index.cgi/wiki?p=HowToMixFirewallsAndHtCondor

- ganglia
- Ganglia hasn't been updated since 2015 so perhaps it is time to look for something else.
- Prometheus/Graphana
- Zabbix
