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 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.
