Timeline for ssh from hyper-v host to linux guest does not work. Does work perfectly from other machines. How to fix?

That is why I think it's rather a hyper-v/vswitch issue, than a problem with the linux configuration. | |

| May 16, 2021 at 10:40 | comment | added | I grok it | sshd is listening on 0.0.0.0:22. ssh is possible from 192.168.1.7 ("test") while it is not possible from 192.168.1.204 ("host"). also, there is no firewall active on linux. | |

Are you sure sshd on Linux is actually listening on this address? (Check with ss -l sport = :22 or netstat -ltn.) Are you sure the Linux firewall isn't rejecting the connection? "Connection refused" is a pretty specific indication that the server explicitly replied with a RST to the connection attempt.
