tcp-env - set up TCP-related environment variables
tcp-env [ -rR ] [ -ttimeout ] program [ arg ... ]
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.
-r (Default.) Attempt to obtain TCPREMOTEINFO from the remote
-R Do not attempt to obtain TCPREMOTEINFO from the remote host.
Give up on the TCPREMOTEINFO connection attempt after timeout
seconds. Default: 30.
