| 2 | .SH NAME | |
| 3 | tcp-env \- set up TCP-related environment variables | |
| 4 | .SH SYNOPSIS | |
| 5 | .B tcp-env | |
| 6 | [ | |
| 7 | .B \-rR | |
| 8 | ] | |
| 9 | [ | |
| 10 | .B \-t\fItimeout | |
| 11 | ] | |
| 12 | .I program | |
| 13 | [ | |
| 14 | .I arg ... | |
| 15 | ] | |
| 16 | .SH DESCRIPTION | |
| 17 | The input for | |
| 18 | .B tcp-env | |
| 19 | must be a TCP connection. | |
| 20 | .B tcp-env | |
| 21 | finds out information about that connection, | |
| 22 | puts the information into several environment variables | |
| 23 | as described in | |
| 24 | .B tcp-environ(5), | |
| 25 | and runs | |
| 26 | .I program | |
| 27 | with the given arguments. | |
| 28 | ||
| 29 | Usually | |
| 30 | .B tcp-env | |
| 31 | is run from | |
| 32 | .BR inetd . | |
| 33 | It might instead be run from another server | |
| 34 | that already sets up the right environment variables; | |
| 35 | if | |
| 36 | .B PROTO | |
| 37 | is set to | |
| 38 | .B TCP | |
| 39 | when | |
| 40 | .B tcp-env | |
| 41 | is invoked, | |
| 42 | .B tcp-env | |
| 43 | assumes that all the other variables are set up properly, | |
| 44 | and it does not check whether the input is a TCP connection. | |
| 45 | .SH OPTIONS | |
| 46 | .TP | |
| 47 | .B \-r | |
| 48 | (Default.) | |

| 50 | .B TCPREMOTEINFO | |
| 51 | from the remote host. | |
| 52 | .TP | |
| 53 | .B \-R | |
| 54 | Do not attempt to obtain | |
| 55 | .B TCPREMOTEINFO | |
| 56 | from the remote host. | |
| 57 | .TP | |
| 58 | .B \-t\fItimeout | |
| 59 | Give up on the | |
| 60 | .B TCPREMOTEINFO | |
| 61 | connection attempt after | |
| 62 | .I timeout | |
| 63 | seconds. | |
| 64 | Default: 30. | |
| 65 | .SH "SEE ALSO" | |
