Known Affected Releases

13.0.0 13.1.0

Description (partial)

Symptom:
An ssh connection fails to reach one or more VMs from whichever node diagnostics.sh is run.

Conditions:
Here are some ideas off the top of my head:

- file descriptor exhaustion
- other ulimit-related problems (try deleting /etc/security/limits.conf!)
- deletion of ~/.ssh keys
- permission changes on home dirs that result in qns keys being inaccessible (as root, try chmod 600 /home)
- ssh not yet started during bootup
- ssh failed for some other reason
- network failures
- dozens of other possibilities. There are many ways to duplicate this issue, and we've seen many of them in TAC over the years.
