Subject: Disable Relayd's error message
Date: Friday, August 13, 2010 - 7:41 am

I just realized that if I telnet to our web servers on port 80 and press 
enter a few times that I get a reply back from relayd that I didn't 
expect "<address>OpenBSD relayd at 127.0.0.1 port 8080</address>" This 
error is correct as we use a PF rdr rule to redirect traffic on our 
firewall to localhost port 8080 where we have relayd listening. I was 
wondering if it's possible to stop this error from being displayed as I 
would prefer not to disclose to the world what software we use.

I've had a look at our  relayd.conf  to see if there is a "return error" 
line but there isn't and I can't see any other way of stopping this 
error from being displayed. Does anyone have any suggestions ?

Thanks
Keith

Yes; the function you're looking for is relay_close_http(), in relay.c

You'll also have to hack the support for setting the string in parse.y

Of course, you could just redefine RELAYD_SERVERNAME in relayd.h, but

You can set return error in relayd.conf to blank or comment it out, I
can't remember which. You'll then get a blank error page though which
may confuse users, so if you want to customise the text other than the
style I believe you'll need to edit the source as shown.
