tcp-env - set up TCP-related environment variables


       tcp-env [ -rR ] [ -ttimeout ] program [ arg ...  ]


       The  input  for tcp-env must be a TCP connection.  tcp-env
       finds out information  about  that  connection,  puts  the
       information   into   several   environment   variables  as
       described in tcp-environ(5), and  runs  program  with  the
       given arguments.

       Usually  tcp-env  is  run from inetd.  It might instead be
       run from another server that already  sets  up  the  right
       environment variables; if PROTO is set to TCP when tcp-env
       is invoked, tcp-env assumes that all the  other  variables
       are  set  up  properly,  and it does not check whether the
       input is a TCP connection.


       -r     (Default.)  Attempt to  obtain  TCPREMOTEINFO  from
              the remote host.

       -R     Do  not  attempt  to  obtain TCPREMOTEINFO from the
              remote host.

              Give up on  the  TCPREMOTEINFO  connection  attempt
              after timeout seconds.  Default: 30.
