The 'sshd' process on the target Linux apparently forks a process to handle each connection . . . with two SSH sessions the Linux target looks like this (pstree -p): |-sshd(1017)-+-sshd(5495)---sshd(5561)---bash(5562) | `-sshd(5595)---sshd(5631)---bash(5632) When the ssh sessions die, only process 1017 is left.
