NAME

tcp-env - set up TCP-related environment variables  

SYNOPSIS

tcp-env [ -rRhH ] [ -llocalname ] [ -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.
-h
(Default.) Look up the remote host name in DNS to set the environment variable TCPREMOTEHOST.
-H
Do not look up the remote host name in DNS; remove the environment variable TCPREMOTEHOST.
-llocalname
Do not look up the local host name in DNS; use localname for the environment variable TCPLOCALHOST. A common choice for localname is 0.
-ttimeout
Give up on the TCPREMOTEINFO connection attempt after timeout seconds. Default: 30.
