tcp-env(1)                                                    General Commands Manual                                                   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. SEE ALSO
tcp-environ(5), inetd(8) tcp-env(1)
