Tried searching around but not finding anything. Hoping someone will know the answer. Is it possible to add more than the 3 feeds that come with OpenVAS? Looking to add feeds from NVD so I can scan with them. Doesn't seem to be possible via the WebGUI.
Feeds from e.g. the NVD probably won't help you. They would need to provide scripts written in NASL if you would like to use them. One of the following blogposts might give you some background knowledge on this topic:

I am a student and in the school website, what I want to do is that I want to busy wait on the certain URL and check if the class i want to register for is open or not. I was wondering if there was a way to constantly check on the website(busy waiting or otherwise) to see if the class is open or not. There is a table Rem where it shows the number of places remaining in the User Interface.
Also what language would you use to solve this problem?
Yes you can. but for that you will probably need to create a script that fetches the value of data from that table.
So something like web scraping should work.
I would definately use php for this stuff.
Google web scraping and you can code the script.
I am not sure if this is the exact thing that will help you, but what you need to do is something similar - See Here
I'm trying to find a better way to move my Expression Engine 2 sites from development to live servers. I have a checklist that I go through, starting with running a find and replace for the old/new URLs and server paths, then I update the database config file. This however misses out a huge amount of settings that I then have to go through and change manually, but I don't see why I should need to (unless these are encrypyed somewhere).
For example, I have to change the "Basepath to Template File Directory" in the Global Template Settings manually, along with member settings and a handful of others. There must be a file or entry with these in somewhere that I can change before I upload but I can't find it.
Does anyone know where these are stored?
Those are stored in the database, unless you are using global config variables.
I would highly recommend looking into some sort of config bootstrap. There are quite a few solutions to this, but it's really up to you to pick what's right for your development style / environment(s).
Take a look at the following articles:
http://eeinsider.com/articles/creating-a-robust-config.php-file/
http://boblet.tumblr.com/post/68095239/ee-localhost
http://eeinsider.com/articles/multi-server-setup-for-ee-2/
I've tried those solutions, but in my opinion the best option is NSM config bootstrap.
Check it out here: [http://ee-garage.com/nsm-config-bootstrap][4]
The only thing (currently) missing from these solutions are new config vars regarding file upload paths and locations. You can add those to any of these solutions by adding the variables detailed in this article:
http://expressionengine.com/user_guide/cp/content/files/file_upload_preferences.html#overriding-upload-paths-and-urls-using-configuration-variables
I know I'm late on this one, but for anyone else searching, this plugin is very useful and I have used it on numerous occasions.
ExpressionEngine stores your website URL and Server Path in a ridiculous number of places.
REElocate helps you update these in one simple step.

I want to make voip applicaton in j2me.I surfed about mjsip2ME. I want to use mjsip with my application. Can any one suggest me for how to do this ?
There's a tutorial, but it is kinda incomplete at the moment, as it does not contain source code, and some sections are labeled "TO DO". However, it contains the list of methodw, with descriptions and a quick, general help.
There's also some info on the web not on the official site, but I hope you're not afraid of chinese :/
How can we restrict a user from saving the page?
Please provide some tips to disable File->Save and View Source options
EDIT: Obviously it can't be done, and probably shouldn't be attempted. But possibly a more interesting variant on this question is how can we make is sufficiently hard for a user to save a page in a usable format such that it is not worth their while doing so? The question doesn't pose a value, but say we were protecting an article subscription site where the user is paying a few hundred dollars per annum for continued access to text.
Since the page has been sent to the client, there will always be a way to get that information. Trying to stop a user from doing this will only frustrate them.
The only way to have a user not be able to save a file is to not send it to them.
While the best answer is "Don't do this," there are ways to make it more difficult for them. And since the point of this site is actually answer the question even if it's bad, here is the best way:
First you'll need to have the page open in a new window where you turn off the address bar and toolbar and everything else. That will make it so the user can't easily get to the File menu at all. To do this you'll need a "splash" page that the user loads to and then when they click a link, it opens the popup that serves the main content of your page. Details on how to create popups without things like the toolbar are here:
http://blazonry.com/javascript/windows.php
Then you'll want to add some javascript to each page that prevents the user from right clicking. Here is one method:
http://javascript.about.com/library/blnoright.htm
Finally, if it's your Javascript code that you don't want to be seen, then obfuscating your code is a pretty effective way to do that. They can still see the code if they have much know-how, but the obfuscated code would be a gigantic pain to actually interpret. There are lots of obfuscators out there; here is a free web-based one:
http://www.javascriptobfuscator.com/
This is far from foolproof. It will stop all "casual" users, but any power user will probably be able to easily figure out a way around it. Still if the idea is to at least prevent a good majority of it then this should suffice.
Update for updated question:
To address your new expanded question, I would say the best way to accomplish what you're saying is to use a format that supports DRM. Adobe Acrobat would probably be the best choice because almost everyone has the reader installed. You can prevent PDF files from being saved to the computer so that they can only be loaded from the webpage by a logged in user. The user could still do a screen capture of the document itself which I don't believe is preventable (unless Adobe Reader has some security in place for this, which they might) but it should be sufficient security for most uses.
Don't do it.
Seriously, if the user can see the page in their browser they can see the source code and/or save it to their computer.
You are fighting a losing battle here.
What about the browser's cache? It can be saved from there.
What about a print screen? That could also save the page.
The only way to prevent a user from saving something is to not show it to them in the first place.
It's really a waste of time and resources to try and do this in html as any method you use can be trivially circumvented.
Instead I would use some other technology to display the data - you can never get around a screen capture. but if you're for instance displaying text and you want to make it hard for the use to save that text for use elsewhere then possible options include
PDF - which can disable save and print. There are extensions to most popular web languages that will write a pdf on the fly. Indeed you might be as well just to go down the DRM route with Adobe and embed a document
Flash - most probably via Flex which could be used to write a general-purpose app to display text and images. The advantage of Flash is that it's easier to set up links than pdf.
Or something else, a custom java applet, or even a vrml plugin and display the text in 3D!
In all cases you could display text against a disruptive background to make OCR more difficult, and images could be watermarked. However nothing is going to stop a determined and resourceful viewer, although you can possibly make it sufficiently hard that it's not worth their time.
The least you can do is... the content is generated dynamically by Javascript. In that way, they cannot simply save it. Of course, in FX, they can still view the generated code and then copy&paste. however, normally people cannot save the page.
It shouldn't be an issue, but if you really don't want a user from seeing your code (javascript, css or html) for some reason, than you could use some obfuscation tool which makes the code less readable.
Try javascript "encoding" and obfuscation.
Something like
if(document.location == 'mydomain.com') {
content = getAjax('mycontent.xml');
// content will hold something like 72, 94, 81, 99, ... - encoded ASCII codes
document.write(String.fromCharCode(content));
}
It will always be possible to save the page, but for non-technical guys it will be harder to make it work.
There are 2 protections
domain name
converting ASCII
It's only pseudocode, but I think you get the idea.
add these to code sets in script tag
document.addEventListener('contextmenu', function (e) {
e.preventDefault();
});
document.onkeydown = function (e) {
return false;
};
I'd like to add one more method which, imho, is hard to circumvent: Ctrl+S! (for me, Apple+S)
how can we make is sufficiently hard for a user to save a page in a usable format such that it is not worth their while doing so
Nothing hard: add on every page: "Personal property of John Stealer, company Zetabeta, paid with credit card 756890987654, billing address ..., subscription expires 12/20".
This is an "extended text format" that I just invented... it has an amazing property: though it looks like a regular text, user is much less willing to print it out and give to others...
