If the user's shell is csh (FreeBSD's standard dialog shell), you
could achieve the goal:
Only problem: I don't know how the shell will act when the user
terminates the vtysh application (^C)...
Idea: When the application vtysh is terminated, the next command
in the .login file will be executed, which is the logout command
that will cause the login shell to exit. This will close the SSH
connection as well.
(I haven't checked this, sorry.)
