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
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.
