Hello, since I upgraded a host to netbsd-10 (from -8), a long-running ssh connection from a host on the same network eventually gets dropped with sshd[16551]: process_output: ssh_packet_write_poll: Connection from user bouyer xx.xx.xx.xx port 56989: Host is down the remote host may be unreachable because of network issues during some nightly task, but certainly not for several minutes. Shouldn't TCP ignore EHOSTDOWN error on established connections, and close it after the ACK timeout instead ? This didn't happen with netbsd-8. -- Manuel Bouyer <[email protected]> NetBSD: 26 ans d'experience feront toujours la difference --
