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.
