How to get an echo from mod_echo?

#1 (**permalink**) 06-27-2003

Hello all,

I thought this would be easy, but it's too much for me.

I've got mod_echo compiled in:
->../bin/httpd -l
Compiled in modules:
core.c
mod_access.c
mod_auth.c
mod_echo.c
(...)

And the directive is at the top level of my httpd.conf (i.e., it's not
within a <Directory> or a <VirtualHost> or <Location>):
ProtocolEcho On
The ServerName is localhost, and it's listening on 127.0.0.1:21000,
but when I start the server, I can't seem to get an echo. If I
request a page, it just serves the page, and if I telnet to port
21000, it responds as a normal webserver -- nothing is echoed:

->telnet localhost 21000
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
**ECHO THIS, PLEASE!!***
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>400 Bad Request</title>
</head><body>
<h1>Bad Request</h1>
<p>Your browser sent a request that this server could not
understand.<br />
</p>
<hr />
<address>Apache/2.0.46 (Unix) Server at localhost Port 80</address>
</body></html>
Connection closed by foreign host.

It behaves like a normal webserver:

->telnet localhost 21000
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
GET /
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Test Page for Apache Installation</title>
(...)

Connection closed by foreign host.

Also, notice the error message: it says it's listening on port 80,
but it's not. I configured it to listen to port 21000 with the Listen
directive, and of course I'm telnetting to port 21000, so obviously
this is a canned error message, or something is really messed up:

->su -c 'nmap -sS localhost'
Password:

Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Interesting ports on fncsejm (127.0.0.1):
(The 1592 ports scanned but not shown below are in state: closed)
Port State Service
21/tcp open ftp
22/tcp open ssh
23/tcp open telnet
25/tcp open smtp
111/tcp open sunrpc
515/tcp open printer
3306/tcp open mysql
6000/tcp open X11
10000/tcp open snet-sensor-mgmt
21000/tcp open unknown

So clearly, nothing is listening on port 80, as netstat agrees with
nmap:

->su -c 'netstat -natp | grep LISTEN'

So what's the juju to get mod_echo to actually echo something?

Thanks in advance
