Thanks. I set these options as per the man page and after restarting the sshd
service it has had no effect on the problem. Appears it may be more related to
bash than sshd per this...
- When the system is idle I have one (1) sshd.exe process (the service).
- Once I log in remotely I have two (2) sshd.exe processes and one (1)
- When I force exit the client terminal emulator one of the sshd.exe
processes goes away almost immediately. But the one bash.exe process is still
there (even as much as hours or days later).
Appears there's some lack of understanding between sshd and bash.
