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.

NAME

       tcp-environ - TCP-related environment variables

DESCRIPTION

       The  following environment variables describe a TCP connection.	They are set up by tcp-env, tcpclient, and tcpserver.  Note that TCPLOCAL-
       HOST, TCPREMOTEHOST, and TCPREMOTEINFO can contain arbitrary characters.

       PROTO
	    The string TCP.

       TCPLOCALHOST
	    The domain name of the local host, with uppercase letters converted to lowercase.  If there is no currently available domain name  for
	    the local IP address, TCPLOCALHOST is not set.

       TCPLOCALIP
	    The IP address of the local host, in dotted-decimal form.

       TCPLOCALPORT
	    The local TCP port number, in decimal.

       TCPREMOTEHOST
	    The domain name of the remote host, with uppercase letters converted to lowercase.	If there is no currently available domain name for
	    the remote IP address, TCPREMOTEHOST is not set.

       TCPREMOTEINFO
	    A connection-specific string, perhaps a username, supplied by the remote host via 931/1413/IDENT/TAP.  If the remote host did not sup-
	    ply connection information, TCPREMOTEINFO is not set.

       TCPREMOTEIP
	    The IP address of the remote host.

       TCPREMOTEPORT
	    The remote TCP port number.
