• Need help making site available externally

  - by White Island

  I'm trying to open a hole in the firewall (ASA 5505, v8.2) to allow external access to a Web application. Via ASDM (6.3?), I've added the server as a Public Server, which creates a static NAT entry [I'm using the public IP that is assigned to 'dynamic NAT--outgoing' for the LAN, after confirming on the Cisco forums that it wouldn't bring everyone's access crashing down] and an incoming rule "any... public_ip... https... allow" but traffic is still not getting through. When I look at the log viewer, it says it's denied by access-group outside_access_in, implicit rule, which is "any any ip deny" I haven't had much experience with Cisco management. I can't see what I'm missing to allow this connection through, and I'm wondering if there's anything else special I have to add. I tried adding a rule (several variations) within that access-group to allow https to the server, but it never made a difference. Maybe I haven't found the right combination? :P I also made sure the Windows firewall is open on port 443, although I'm pretty sure the current problem is Cisco, because of the logs. :) Any ideas? If you need more information, please let me know. Thanks Edit: First of all, I had this backward. (Sorry) Traffic is being blocked by access-group "inside_access_out" which is what confused me in the first place. I guess I confused myself again in the midst of typing the question. Here, I believe, is the pertinent information. Please let me know what you see wrong. access-list acl_in extended permit tcp any host PUBLIC_IP eq https access-list acl_in extended permit icmp CS_WAN_IPs 255.255.255.240 any access-list acl_in remark Allow Vendor connections to LAN access-list acl_in extended permit tcp host Vendor any object-group RemoteDesktop access-list acl_in remark NetworkScanner scan-to-email incoming (from smtp.mail.microsoftonline.com to PCs) access-list acl_in extended permit object-group TCPUDP any object-group Scan-to-email host NetworkScanner object-group Scan-to-email access-list acl_out extended permit icmp any any access-list acl_out extended permit tcp any any access-list acl_out extended permit udp any any access-list SSLVPNSplitTunnel standard permit LAN_Subnet 255.255.255.0 access-list nonat extended permit ip VPN_Subnet 255.255.255.0 LAN_Subnet 255.255.255.0 access-list nonat extended permit ip LAN_Subnet 255.255.255.0 VPN_Subnet 255.255.255.0 access-list inside_access_out remark NetworkScanner Scan-to-email outgoing (from scanner to Internet) access-list inside_access_out extended permit object-group TCPUDP host NetworkScanner object-group Scan-to-email any object-group Scan-to-email access-list inside_access_out extended permit tcp any interface outside eq https static (inside,outside) PUBLIC_IP LOCAL_IP[server object] netmask 255.255.255.255 I wasn't sure if I needed to reverse that "static" entry, since I got my question mixed up... and also with that last access-list entry, I tried interface inside and outside - neither proved successful... and I wasn't sure about whether it should be www, since the site is running on https. I assumed it should only be https.

• H.264 over RTP - Identify SPS and PPS Frames

  - by Toby

  I have a raw H.264 Stream from an IP Camera packed in RTP frames. I want to get raw H.264 data into a file so I can convert it with ffmpeg. So when I want to write the data into my raw H.264 file I found out it has to look like this: 00 00 01 [SPS] 00 00 01 [PPS] 00 00 01 [NALByte] [PAYLOAD RTP Frame 1] // Payload always without the first 2 Bytes -> NAL [PAYLOAD RTP Frame 2] [... until PAYLOAD Frame with Mark Bit received] // From here its a new Video Frame 00 00 01 [NAL BYTE] [PAYLOAD RTP Frame 1] .... So I get the SPS and the PPS from the Session Description Protocol out of my preceding RTSP communication. Additionally the camera sends the SPS and the PPSin two single messages before starting with the video stream itself. So I capture the messages in this order: 1. Preceding RTSP Communication here ( including SDP with SPS and PPS ) 2. RTP Frame with Payload: 67 42 80 28 DA 01 40 16 C4 // This is the SPS 3. RTP Frame with Payload: 68 CE 3C 80 // This is the PPS 4. RTP Frame with Payload: ... // Video Data Then there come some Frames with Payload and at some point a RTP Frame with the Marker Bit = 1. This means ( if I got it right) that I have a complete video frame. Afer this I write the Prefix Sequence ( 00 00 01 ) and the NALfrom the payload again and go on with the same procedure. Now my camera sends me after every 8 complete Video Frames the SPS and the PPS again. ( Again in two RTP Frames, as seen in the example above ). I know that especially the PPS can change in between streaming but that's not the problem. My questions are now: 1. Do I need to write the SPS/PPS every 8th Video Frame? If my SPS and my PPS don't change it should be enough to have them written at the very beginning of my file and nothing more? 2. How to distinguish between SPS/PPS and normal RTP Frames? In my C++ Code which parses the transmitted data I need make a difference between the RTP Frames with normal Payload an the ones carrying the SPS/PPS. How can I distinguish them? Okay the SPS/PPS frames are usually way smaller, but that's not a save call to rely on. Because if I ignore them I need to know which data I can throw away, or if I need to write them I need to put the 00 00 01 Prefix in front of them. ? Or is it a fixed rule that they occur every 8th Video Frame?

• Are virtualization softwares allow guest Operating Systems to fully utilize host's drivers?

  - by afriza

  I like to use linux distros except for the lack of drivers that can fully utilize the hardware. As an example, graphic card drivers for linux cannot perform equally with their windows' counterpart even if they are from the same vendor! Does using virtualization reduce this problem? Which virtualization technologies / softwares perform well for this case?

• How to check undefined javascript value in facebook?

  - by Murvinlai

  In normal javascript, I can check either if (i == undefined) or if (i === undefined) or the "typeof" however, within facebook, it will have the api_key append as the prefix in undefined. i.e. it will become if (a12345_i == a12345_undefined) which is NOT undefined so, what can I do to find out the variable is undefined or not?

• Using PHP's IMAP library triggers Kaspersky's Antivirus

  - by TMG

  Hello, I just started today working with PHP's IMAP library, and while imap_fetchbody or imap_body are called, it is triggering my Kaspersky antivirus. The viruses are Trojan.Win32.Agent.dmyq and Trojan.Win32.FraudPack.aoda. I am running this off a local development machine with XAMPP and Kaspersky AV. Now, I am sure there are viruses there since there is spam in the box (who doesn't need a some viagra or vicodin these days?). And I know that since the raw body includes attachments and different mime-types, bad stuff can be in the body. So my question is: are there any risks using these libraries? I am assuming that the IMAP functions are retrieving the body, caching it to disk/memory and the AV scanning it sees the data. Is that correct? Are there any known security concerns using this library (I couldn't find any)? Does it clean up cached message parts perfectly or might viral files be sitting somewhere? Is there a better way to get plain text out of the body than this? Right now I am using the following code (credit to Kevin Steffer): function get_mime_type(&$structure) { $primary_mime_type = array("TEXT", "MULTIPART","MESSAGE", "APPLICATION", "AUDIO","IMAGE", "VIDEO", "OTHER"); if($structure->subtype) { return $primary_mime_type[(int) $structure->type] . '/' .$structure->subtype; } return "TEXT/PLAIN"; } function get_part($stream, $msg_number, $mime_type, $structure = false, $part_number = false) { if(!$structure) { $structure = imap_fetchstructure($stream, $msg_number); } if($structure) { if($mime_type == get_mime_type($structure)) { if(!$part_number) { $part_number = "1"; } $text = imap_fetchbody($stream, $msg_number, $part_number); if($structure->encoding == 3) { return imap_base64($text); } else if($structure->encoding == 4) { return imap_qprint($text); } else { return $text; } } if($structure->type == 1) /* multipart */ { while(list($index, $sub_structure) = each($structure->parts)) { if($part_number) { $prefix = $part_number . '.'; } $data = get_part($stream, $msg_number, $mime_type, $sub_structure,$prefix . ($index + 1)); if($data) { return $data; } } // END OF WHILE } // END OF MULTIPART } // END OF STRUTURE return false; } // END OF FUNCTION $connection = imap_open($server, $login, $password); $count = imap_num_msg($connection); for($i = 1; $i <= $count; $i++) { $header = imap_headerinfo($connection, $i); $from = $header->fromaddress; $to = $header->toaddress; $subject = $header->subject; $date = $header->date; $body = get_part($connection, $i, "TEXT/PLAIN"); }

• Rails 3 shows 404 error instead of index.html (nginx + unicorn)

  - by Miko

  I have an index.html in public/ that should be loading by default but instead I get a 404 error when I try to access http://example.com/ The page you were looking for doesn't exist. You may have mistyped the address or the page may have moved. This has something to do with nginx and unicorn which I am using to power Rails 3 When take unicorn out of the nginx configuration file, the problem goes away and index.html loads just fine. Here is my nginx configuration file: upstream unicorn { server unix:/tmp/.sock fail_timeout=0; } server { server_name example.com; root /www/example.com/current/public; index index.html; keepalive_timeout 5; location / { try_files $uri @unicorn; } location @unicorn { proxy_pass http://unicorn; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; } } My config/routes.rb is pretty much empty: Advertise::Application.routes.draw do |map| resources :users end The index.html file is located in public/index.html and it loads fine if I request it directly: http://example.com/index.html To reiterate, when I remove all references to unicorn from the nginx conf, index.html loads without any problems, I have a hard time understanding why this occurs because nginx should be trying to load that file on its own by default. -- Here is the error stack from production.log: Started GET "/" for 68.107.80.21 at 2010-08-08 12:06:29 -0700 Processing by HomeController#index as HTML Completed in 1ms ActionView::MissingTemplate (Missing template home/index with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml, :haml], :formats=>[:html], :locale=>[:en, :en]} in view paths "/www/example.com/releases/20100808170224/app/views", "/www/example.com/releases/20100808170224/vendor/plugins/paperclip/app/views", "/www/example.com/releases/20100808170224/vendor/plugins/haml/app/views"): /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/paths.rb:14:in `find' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/lookup_context.rb:79:in `find' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/base.rb:186:in `find_template' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/render/rendering.rb:45:in `_determine_template' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/render/rendering.rb:23:in `render' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/haml-3.0.15/lib/haml/helpers/action_view_mods.rb:13:in `render_with_haml' etc... -- nginx error log for this virtualhost comes up empty: 2010/08/08 12:40:22 [info] 3118#0: *1 client 68.107.80.21 closed keepalive connection My guess is unicorn is intercepting the request to index.html before nginx gets to process it.

• Searches (and general querying) with HBase and/or Cassandra (best practices?)

  - by alexeypro

  I have User model object with quite few fields (properties, if you wish) in it. Say "firstname", "lastname", "city" and "year-of-birth". Each user also gets "unique id". I want to be able to search by them. How do I do that properly? How to do that at all? My understanding (will work for pretty much any key-value storage -- first goes key, then value) u:123456789 = serialized_json_object ("u" as a simple prefix for user's keys, 123456789 is "unique id"). Now, thinking that I want to be able to search by firstname and lastname, I can save in: f:Steve = u:384734807,u:2398248764,u:23276263 f:Alex = u:12324355,u:121324334 so key is "f" - which is prefix for firstnames, and "Steve" is actual firstname. For "u:Steve" we save as value all user id's who are "Steve's". That makes every search very-very easy. Querying by few fields (properties) -- say by firstname (i.e. "Steve") and lastname (i.e. "l:Anything") is still easy - first get list of user ids from "f:Steve", then list from "l:Anything", find crossing user ids, an here you go. Problems (and there are quite a few): Saving, updating, deleting user is a pain. It has to be atomic and consistent operation. Also, if we have size of value limited to some value - then we are in (potential) trouble. And really not of an answer here. Only zipping the list of user ids? Not too cool, though. What id we want to add new field to search by. Eventually. Say by "city". We certainly can do the same way "c:Los Angeles" = ..., "c:Chicago" = ..., but if we didn't foresee all those "search choices" from the very beginning, then we will have to be able to create some night job or something to go by all existing User records and update those "c:CITY" for them... Quite a big job! Problems with locking. User "u:123" updates his name "Alex", and user "u:456" updates his name "Alex". They both have to update "f:Alex" with their id's. That means either we get into overwriting problem, or one update will wait for another (and imaging if there are many of them?!). What's the best way of doing that? Keeping in mind that I want to search by many fields? P.S. Please, the question is about HBase/Cassandra/NoSQL/Key-Value storages. Please please - no advices to use MySQL and "read about" SELECTs; and worry about scaling problems "later". There is a reason why I asked MY question exactly the way I did. :-)

• Custom validation works in development but not in unit test

  - by Geolev

  I want to validate that at least one of two columns have a value in my model. I found somewhere on the web that I could create a custom validator as follows: # Check for the presence of one or another field: # :validates_presence_of_at_least_one_field :last_name, :company_name - would require either last_name or company_name to be filled in # also works with arrays # :validates_presence_of_at_least_one_field :email, [:name, :address, :city, :state] - would require email or a mailing type address module ActiveRecord module Validations module ClassMethods def validates_presence_of_at_least_one_field(*attr_names) msg = attr_names.collect {|a| a.is_a?(Array) ? " ( #{a.join(", ")} ) " : a.to_s}.join(", ") + "can't all be blank. At least one field must be filled in." configuration = { :on => :save, :message => msg } configuration.update(attr_names.extract_options!) send(validation_method(configuration[:on]), configuration) do |record| found = false attr_names.each do |a| a = [a] unless a.is_a?(Array) found = true a.each do |attr| value = record.respond_to?(attr.to_s) ? record.send(attr.to_s) : record[attr.to_s] found = !value.blank? end break if found end record.errors.add_to_base(configuration[:message]) unless found end end end end end I put this in a file called lib/acs_validator.rb in my project and added "require 'acs_validator'" to my environment.rb. This does exactly what I want. It works perfectly when I manually test it in the development environment but when I write a unit test it breaks my test environment. This is my unit test: require 'test_helper' class CustomerTest < ActiveSupport::TestCase # Replace this with your real tests. test "the truth" do assert true end test "customer not valid" do puts "customer not valid" customer = Customer.new assert !customer.valid? assert customer.errors.invalid?(:subdomain) assert_equal "Company Name and Last Name can't both be blank.", customer.errors.on(:contact_lname) end end This is my model: class Customer < ActiveRecord::Base validates_presence_of :subdomain validates_presence_of_at_least_one_field :customer_company_name, :contact_lname, :message => "Company Name and Last Name can't both be blank." has_one :service_plan end When I run the unit test, I get the following error: DEPRECATION WARNING: Rake tasks in vendor/plugins/admin_data/tasks, vendor/plugins/admin_data/tasks, and vendor/plugins/admin_data/tasks are deprecated.

($(elem).attr(match[3]) && $(elem).attr(match[3]).match(/\.(gif|jpe?g|png|bmp)$/i)); }; $.fn.imgPreview = function(userDefinedSettings){ var s = $.extend({ /* DEFAULTS */ // CSS to be applied to image: imgCSS: {}, // Distance between cursor and preview: distanceFromCursor: {top:2, left:2}, // Boolean, whether or not to preload images: preloadImages: true, // Callback: run when link is hovered: container is shown: onShow: function(){}, // Callback: container is hidden: onHide: function(){}, // Callback: Run when image within container has loaded: onLoad: function(){}, // ID to give to container (for CSS styling): containerID: 'imgPreviewContainer', // Class to be given to container while image is loading: containerLoadingClass: 'loading', // Prefix (if using thumbnails), e.g. 'thumb_' thumbPrefix: '', // Where to retrieve the image from: srcAttr: 'rel' }, userDefinedSettings), $container = $('<div/>').attr('id', s.containerID) .append('<img/>').hide() .css('position','absolute') .appendTo('body'), $img = $('img', $container).css(s.imgCSS), // Get all valid elements (linking to images / ATTR with image link): $collection = this.filter(':linkingToImage(' + s.srcAttr + ')'); // Re-usable means to add prefix (from setting): function addPrefix(src) { return src.replace(/(\/?)([^\/]+)$/,'$1' + s.thumbPrefix + '$2'); } if (s.preloadImages) { (function(i){ var tempIMG = new Image(), callee = arguments.callee; tempIMG.src = addPrefix($($collection[i]).attr(s.srcAttr)); tempIMG.onload = function(){ $collection[i + 1] && callee(i + 1); }; })(0); } $collection .mousemove(function(e){ $container.css({ top: e.pageY + s.distanceFromCursor.top + 'px', left: e.pageX + s.distanceFromCursor.left + 'px' }); }) .hover(function(){ var link = this; $container .addClass(s.containerLoadingClass) .show(); $img .load(function(){ $container.removeClass(s.containerLoadingClass); $img.show(); s.onLoad.call($img[0], link); }) .attr( 'src' , addPrefix($(link).attr(s.srcAttr)) ); s.onShow.call($container[0], link); }, function(){ $container.hide(); $img.unbind('load').attr('src','').hide(); s.onHide.call($container[0], this); }); // Return full selection, not $collection! return this; }; })(jQuery); It works perfectly in all browsers apart from IE, which it does nothing, no errors, no clues? I have a funny feeling IE doesn't support attr? Can anyone offer any advice?

• What are the valid characters for a Mime Multipart message ContentId "CID:" ?

  - by mP

  From reading the RFC it appears that CID can/must only contain characters from the same set as those permissable by a regular URI. Is this correct. Im asking because I wish to writeup a simple helper that takes a CIDs prefix and adds a counter when generating CID for mime multitypes attachments.

• Symantec Gateway Security 320 VPN/Port Forwarding trouble

  - by Owl

  How do I check to see if port forward is enabled with one of my dynamic tunnels on this device? I'm having trouble using a feature in our software that requires a vpn to be used. My firewalls shows it as connected but I'm unable to ping the subnet ip. Our software vendor told me that port forwarding might be causing this problem, but I didn't set up this network I'm on and I don't fully know symantec hardware.

• XSLT, JSTL e JSF

  - by Paulo S.

  I have a xml file which I want to transform in a jsf code page. To do that I've created a xsl file. xml: <?xml version='1.0' encoding='ISO-8859-1'?> <questionario xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:noNamespaceSchemaLocation='Schema2.xsd'> <componente nome='input'> <id>input1</id> </componente> <componente nome='input'> <id>input2</id> </componente> </questionario> code: <%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/xml" prefix="x" %> <c:set var="xml" value="${questionarioXSLBean.xml}"/> <c:set var="xsl"> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" exclude-result-prefixes="f h"> <xsl:template match="/"> <xsl:for-each select="questionario/componente"> <xsl:if test="attribute::nome = 'input'"> <xsl:variable name="id"> <xsl:value-of select="id" /> </xsl:variable> <h:inputText id="{$id}"/> </xsl:if> </xsl:for-each> </xsl:template> </xsl:stylesheet> </c:set> <x:transform xml="${xml}" xslt="${xsl}" /> The problem is that nothing is shown in my screen because the generated code for <h:inputText id="input1"/> is <h:inputText id="input_1" xmlns:h="http://java.sun.com/jsf/html"/> how can I replace the xmlns:h="http://java.sun.com/jsf/html" or suppress it. Thanks! Update: Let me clarify what I want to do. I want to generate a jsf page dynamically depending on the attributes of a xml file, for instance, 2 input texts, 3 check boxes, etc. To make the transformation to jsf I thought in two approaches, one using jstl and another using xslt. The problem with the former is that I couldn't integrate jstl with jsf code (to set jsf components attributes using jstl variables) and with the last approach, I'm facing the problem described above.I wouldn't like to create components in java (UIComponents). Any suggestions?
