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.
