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.
