From (1) on the server side: "LogLevel Gives the verbosity level that is used when logging messages from sshd(8). The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2, and DEBUG3. The default is INFO. DEBUG and DEBUG1 are equivalent. DEBUG2 and DEBUG3 each specify higher levels of debugging output. Logging with a DEBUG level violates the privacy of users and is not recommended." On Windows, you need to increase the verbosity of the client (putty/Teraterm ...) or try Cygwin to use 'ssh -vvv' on windows. 1) https://linux.die.net/man/5/sshd_config -- John Doe
