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
       TCPLOCALHOST,  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
            supply connection information, TCPREMOTEINFO is not set.

       TCPREMOTEIP
            The IP address of the remote host.

       TCPREMOTEPORT
            The remote TCP port number.
