NAME
          tcp-env - set up TCP-related environment variables

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

     DESCRIPTION
          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.

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

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

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