Last modified: 2024-04-30 16:37:17 UTC
QA: additional regression testing: Try ssh connects from: - unfixed openssh client to fixed server - fixed openssh client to unfixed server - fixed openssh client to fixed server - try non-openssh client (putty?) to fixed server (putty is in packagbehub of SLE15) Not necessary on all products or architecutres, but just once per incident.
