tcp-env1
Set up tcp-related environment variables
Usage
tcp-env [-rR]
[-ttimeout]
program
[arg ...]
Overview
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.
-

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