tcp-env(1)
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 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.
- -ttimeout
- Give up on the TCPREMOTEINFO connection attempt after timeout seconds. Default: 30.
