Yes, you said totally right, it is exactly my problem. I have tried your suggestion, someone already logged on that same console.
but ansible still reports Authentication or permission failure. now, I want to study ansible's source code, try to rewrite the code after initial connection. it should send a 'enter' key, and try to login if the console is not logged on. thank you for your help, I will update my trial later. 在 2017年2月15日星期三 UTC+8下午8:55:40，Dag Wieers写道： > > On Tue, 14 Feb 2017, rong zhao wrote: > > > My remote hosts' management port is serial console over LAN. > > When connect by ssh manually, I use ops account connect to remote > hosts, > > and then it become the Linux console, I just run ssh command. > > > > Now, I use ansible -m ping to test reachable, it reports: > > "Authentication or permission failure.
