I'm using ~/.ssh/config for logging to the internal.local corporate server: Host internal.local ProxyCommand ssh -e none corporate.proxy nc %h %p But after closing session (typing exit), my sshd session on server stays still active (I see it through different connection). Hot do I close session or change my config in the appropriate way, to eleminate hang sessions? First check from the second, root session: ps -fu user_name user_name 861 855 0 16:58:16 pts/3 0:00 -bash user_name 855 854 0 16:58:13 ? 0:00 /usr/lib/ssh/sshd After logging out: user_name 855 854 0 16:58:13 ? 0:00 /usr/lib/ssh/sshd Just after scp files to/from the internal.local a new scp sessions still hangs on the server.
