No it does not. Please see the below observation.

I put this trap code in tracklogin.sh

Code:

trap "exit;" 2

and inject the tracklogin.sh in my .profile as shown in the OP.

When I login to the server it prompts me for Reason.

But when I press Crtl+C it Does Not log me out.

Instead I can continue without being enforced or killed out of the server.

Please see the output below.

Code:

IF YOU DO NOT CONSENT, LOG OFF NOW.

NAME

       fence_baytech - I/O Fencing agent for Baytech RPC switches in combination with a Cyclades Terminal Server

SYNOPSIS

       fence_baytech [OPTION]...

DESCRIPTION

       This fencing agent is written for the Baytech RPC27-20nc in combination with a Cyclades terminal server.  The Cyclades TS exports the RPC's
       serial port via a Telnet interface.  Other interfaces, such as SSH, are possible.  However, this script relies  upon  the  assumption  that
       Telnet  is used.  Future features to this agent would allow the agent to work with a multitude of different communication protocols such as
       Telnet, SSH or Kermit.

       The other assumption that is made is that Outlet names do not end in space.  The name "Foo" and "Foo    " are identical when the RPC prints
       them with the status command.

       fence_baytech  accepts  options	on the command line as well as from stdin.  fenced sends parameters through stdin when it execs the agent.
       fence_baytech can be run by itself with command line options which is useful for testing.

       Vendor URL: http://www.baytech.net

       -a host
	      IP address or hostname to connect to.
