What version of putty are you using? Without it it is hard to tell. – tukan – 2017-09-07T08:55:48.537
Release 0.70, 64bit Windows platform :) – NaturalBornCamper – 2017-09-07T09:37:59.997
Great. Now where are you trying to connect? Server, PC, modem, switch, etc.? – tukan – 2017-09-07T10:39:12.907
On a linux server, with Debian9. I tried hitting backspace in case there were invisible characters already in there but it didn't do anything – NaturalBornCamper – 2017-09-07T11:20:48.710
I recommend running wireshark on the server or client to see what is actually sent the first time when you enter the passwd. – tukan – 2017-09-07T12:00:53.440
Let us know how it goes. I'm quite interested what is sent the first time around. I don't have any VM with Debian9 to test so I'll wait for your results. – tukan – 2017-09-08T06:17:20.607
