Trouble-Shooting
When an ssh command fails it often helps to look at
debug messages.
Debug messages can easily be marked with the mouse and copied into a
support e-mail.
(Making screenshots is discouraged.)
OpenSSH (Linux, MacOS, Windows)
Debug messages can be switched on by adding the -v
option up to 3 times:
$ssh-vvvsame-parameters-as-before
PuTTY (Windows)
Debug messages can be viewed after right click on the title-bar of the PuTTY window and selecting Event Log.
