So based on this old question of mine I figured out that I can reset the access point and access it using telnet through a wired Ethernet connection.

I have set a new password, I have set up the Ethernet connection so it doesn't conflict with my main router, and most importantly I have specified the country because this turns the WIFI radio on - except it didn't...

I have the Getting Started Guide and also the Management and Configuration Guide as well as this official FAQ. They all indicate that the WIFI radio is turned on when I have specified the country.

--> Why does the status still say "Radio Status : Disabled"?

I have a HP Wireless Access Point 420 (J8131A) and I am facing the problem that its admin interface uses either an ActiveX plugin or a JAR file - I'm not sure because none of browsers on none of my machines can load it.

Even on Windows + Internet Explorer, having turned off any and all security settings, I can't get the admin menu to load. And without an admin menu, well, it's mostly a paper weight.

Can you give me any tips on how to progress from here? I'd like to avoid ditching the unit but I realize it may be the only option. Your comments are much appreciated!

What I have:
I have an iPhone app that sends HTTP POST requests (XML format) to a web service written in PHP. This is on a hosted virtual private server so I can edit httpd.conf and other files on the server, and restart Apache.

The problem:
The web service works perfectly as long as the request is not too large, but around 1MB is the limit. After that, the server responds with:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>413 Request Entity Too Large</title>
</head><body>
<h1>Request Entity Too Large</h1>
The requested resource<br />/<br />
does not allow request data with POST requests, or the amount of data
provided in the request exceeds the capacity limit.
</body></html>

The web service writes its own log file, and I can see that small messages are processed fine. Larger messages are not logged at all so I guess that something in Apache rejects them before they even reach the web service?

Things I've tried without success:
(I've restarted Apache after every change. These steps are incremental.)

  1. hosting provider's web-based configuration panel: disable mod_security
  2. httpd.conf: LimitXMLRequestBody 0 and LimitRequestBody 0
  3. httpd.conf: LimitXMLRequestBody 100000000 and LimitRequestBody 100000000
  4. httpd.conf: SecRequestBodyLimit 100000000

At this stage, Apache's error.log contains a message:
ModSecurity: Request body no files data length is larger than the configured limit (1048576)

The fact that there's an error statement by ModSecurity indicates that my step #1 didn't really take. Apache's access.log looks like this, with 3 successful small messages and 2 failed large messages:

"POST / HTTP/1.1" 200 310 "-" "Audiopad/1.0 CFNetwork/548.0.4 Darwin/11.0.0"
"POST / HTTP/1.1" 200 310 "-" "Audiopad/1.0 CFNetwork/548.0.4 Darwin/11.0.0"
"POST / HTTP/1.1" 200 310 "-" "Audiopad/1.0 CFNetwork/548.0.4 Darwin/11.0.0"
"POST / HTTP/1.1" 413 464 "-" "Audiopad/1.0 CFNetwork/548.0.4 Darwin/11.0.0"
"POST / HTTP/1.1" 413 464 "-" "Audiopad/1.0 CFNetwork/548.0.4 Darwin/11.0.0"

Apache's error.log has this info about the large messages:

[error] [client 194.24.138.43] ModSecurity: Request body no files data length is larger than the configured limit (1048576). [hostname "webservice-audiopad.golfbravo.net"] [uri "/"]
[error] [client 194.24.138.43] ModSecurity: Request body no files data length is larger than the configured limit (1048576). [hostname "webservice-audiopad.golfbravo.net"] [uri "/"]

However, I don't see the value 1048576 anywhere in httpd.conf.

What more can I try, to get the web service to receive large messages?

I'm managing a phpBB-based forum that gets hit hard by spammers signing up fake accounts. To combat this, we enabled "administrator activation required", but it's not working so well: When a new user signs up, I get an email with a link to activate that user. However, there's no link to let me easily look at the user first; it goes straight to activation.

I'd like to try a different approach, along these lines:

  1. I'd like to allow registrations without my approval; instead, the user must get a mail with an activation link.
  2. I'd like a designated moderator group to approve all posts made by newly registered users. This should be done through the forum's web-based moderation control panel.
  3. When a new user posts a spammy message, I want the moderator group to kill the message and the account.
  4. When a new user has posted a few non-spammy messages, he's whitelisted and further postings require no approval.

How do I achieve this setup? -or- Is there a similar but smarter approach?

UPDATE: I finally found a watertight solution: http://CleanTalk.org -- it's a paid service but for a measly $8 per year it's well worth the money. So far the filter has worked 100% accurately, without any spammers getting through and without blocking legit users. I am impressed.

I've read that SPF is a way to ensure that spam sent in my name is evidently fake, and I'd like to use that. How do I set up SPF? Or is it already in effect? I have two domains hosted on Dreamhost.com, and I use Google Apps to read mail on both domains (separately).

I have used this tool to check if SPF is present for my domains. One domain has SPF, one doesn't.

But it gets more complicated than that:

A) The domain with SPF uses Dreamhost as MX. Mail accounts on this domain are set up to forward to specific Google Apps accounts.

  • Is my SPF ignored when sending mail from Google Apps?

B) The domain without SPF uses Google as MX. I want to add SPF to this domain.

  • Can I add SPF under this domain's DNS records, or should this be done at Google (outside my control)?

C) Further, the users are in several countries using several ISP's. Some don't use the Gmail web interface but rather a mail client (Thunderbird, Outlook). So it's really difficult to say which IP addresses are "ours". This goes for both domains.

  • What IP addresses can/should/must I (not?) specify in my SPF records?
