• New Features Of WordPress 3.3 You Must Know

  - by Gopinath

  After months of beta testing, WordPress 3.3 version is going to be released at the end of this month. There are several new features packed in the new version and few of them are going to excite WordPress admins. In this post we are going to discuss about the exciting new features. 1. Drag and Drop Media Uploads One of the biggest improvements in this version of WordPress is it’s all new media uploader. Now you can upload multiple files by just dragging & dropping, instantly resize  the images and filter files by their type. The media upload sports a brand new look WordPress adopted the Pupload plugin to power its media uploader component and it’s written by the same team who created the popular TinyMCE editor plugin. 2. Improved Admin Bar(Toolbar) The admin bar or newly called toolbar has got handful of makeovers. The not so much used items like Search box and other elements are removed to make sure that the bar is not clumsy. The user menu and the related options are moved to the right like how we see in Google’s user bar. Also there are few changes to the colour of the bar to make it more eye friendly. 3. Fly out Admin Menus All the left side bar menus of WordPress admin are now sports a fly out menu style to save a click. In the previous versions if you want to access a sub menu on the left side bar, you need to first click on the category and then choose the menu item from the expanded list. Now on just mouse over you will see a flyout of menu items. 4. Adaptive Admin – Layout Auto Adjust To Fit Various Devices If you own an iPad or any other so called tablets then you are going to love this feature. The admin site of WordPress has got a lot more friendly with tablets and smartphones. WordPress now auto adjusts layout to fit the device through which you are accessing the admin site.  Accessing admin dashboard on your tablets is going to be more fun. 5. Other Features Now that we have read the most useful 4 features here is a small list of other features that may interest you Nice Tooltips are displayed where ever possible to help the newbies to understand the usage of admin site Responsive Layouts jQuery 1.7 and jQuery UI 1.8.16 are the power horses of WordPress Performance improvements This article titled,New Features Of WordPress 3.3 You Must Know, was originally published at Tech Dreams.

• core.* files eating up server space (~50MB)

  - by skytreader

  I'm renting server space from someone and, upon logging in my control panel after quite sometime, noticed an abnormal spike (~50MB) in the disk usage. Upon investigating, I found a lot of core.* files scattered around my public_html directory. Each one is more than 5MB in size but no more than 6MB. The * part is all numbers (in programming regex, that should be core\.\d+). I downloaded one and checked the contents. There was a lot of balderdash characters (NUL mostly, but also a scattering of ETB, ETX, STX) but there's this block of readable text which says: This text is part of the internal format of your mail folder, and is not a real message. It is created automatically by the mail system software. If deleted, important folder data will be lost, and it will be re-created with the data reset to initial values. Pretty self-explanatory. A few blocks above the text are some more readable messages that look like logs but is sandwiched in between non printable characters. I've extracted some below. Scan not valid for mh mailboxes Bogus character 0x%x in news state Can't rewrite news state %.80s Error closing backup news state %.80s No state for newsgroup %.80s found Now, a few concerns: Am I under attack? The messages seem to be about my webmail but I don't use my personal webmail that much---only for a vanity email address and an inbox for an outdated comments system. However, lately, I seem to notice a spike in the spam for my vanity mail. (Note: the comments system is covered by a captcha but every now and then some get through. My vanity email has a spam filter but it isn't as good as I'd like). Next, if this is a feature, can I turn it off? Is it advisable to? I've only 150MB so you see why I'm fretting over a 50MB spike. Some final details: my only server-side scripts are in PHP. The directory which accumulated the most number of these core files is the one containing the Wordpress-managed subdomain of my site. I manage my server through CPanel. Lastly, I decided to delete this files and after some checking nothing seems amiss in my websites nor in my mail. They are indeed the ones responsible for the ~50MB spike as my disk space usage is back to expected.

• JavaOne 2013: (Key) Notes of a conference – State of the Java platform and all the roadmaps by Amis

  - by JuergenKress

  Last week’s JavaOne conference provided insights in the roadmap of the Java platform as well as in the current state of things in the Java community. The close relationship between Oracle and IBM concerning Java, the (continuing) lack of such a relationship with Google, the support from Microsoft for Java applications on its Azure cloud and the vibrant developer community – with over 200 different Java User Groups in many countries of the world. There were no major surprises or stunning announcements. Java EE 7 (release in June) was celebrated, the progress of Java 8 SE explained as well as the progress on Java Embedded and ME. The availability of NetBeans 7.4 RC1 and JDK 8 Early Adopters release as well as the open sourcing of project Avatar probably were the only real news stories. The convergence of JavaFX and Java SE is almost complete; the upcoming alignment of Java SE Embedded and Java ME is the next big consolidation step that will lead to a unified platform where developers can use the same skills, development tools and APIs on EE, SE, SE Embedded and ME development. This means that anything that runs on ME will run on SE (Embedded) and EE – not necessarily the reverse because not all SE APIs are part of the compact profile or the ME environment. However, the trimming down of the SE libraries and the increased capabilities of devices mean that a pretty rich JVM runs on many devices – such as JavaFX 8 on the Raspberry PI. The major theme of the conference was Internet of Things. A world of things that are smart and connected, devices like sensors, cameras and equipment from cars, fridges and television sets to printers, security gates and kiosks that all run Java and are all capable of sending data over local network connections or directly over the internet. The number of devices that has these capabilities is rapidly growing. This means that the number of places where Java programs can help program the behavior of devices is growing too. It also means that the volume of data generated is expanding and that we have to find ways to harvest that data, possibly do a local pre-processing (filter, aggregate) and channel the data to back end systems. Terms typically used are edge devices (small, simple, publishing data), gateways (receiving data from many devices, collecting and consolidating, pre-processing, sending onwards to back end – typically using real time event processing) and enterprise services – receiving the data-turned-information from the gateways to further consolidate, distribute and act upon. A cheap device like the Raspberry PI is a perfect way to get started as a Java developer with what embedded (device) programming means and how interaction with physical input and output takes place. Roadmaps The over all progress on Java is visualized in this overview: Read the full article here.

• Adding Facebook Open Graph Tags to an MVC Application

  - by amaniar

  If you have any kind of share functionality within your application it’s a good practice to add the basic Facebook open graph tags to the header of all pages. For an MVC application this can be as simple as adding these tags to the Head section of the Layouts file.<head> <title>@ViewBag.Title</title> <meta property="og:title" content="@ViewBag.FacebookTitle" /> <meta property="og:type" content="website"/> <meta property="og:url" content="@ViewBag.FacebookUrl"/> <meta property="og:image" content="@ViewBag.FacebookImage"/> <meta property="og:site_name" content="Site Name"/> <meta property="og:description" content="@ViewBag.FacebookDescription"/></head>  These ViewBag properties can then be populated from any action: private ActionResult MyAction() { ViewBag.FacebookDescription = "My Actions Description"; ViewBag.FacebookUrl = "My Full Url"; ViewBag.FacebookTitle = "My Actions Title"; ViewBag.FacebookImage = "My Actions Social Image"; .... } You might want to populate these ViewBag properties with default values when the actions don’t populate them. This can be done in 2 places. 1. In the Layout itself. (check the ViewBag properties and set them if they are empty) @{ ViewBag.FacebookTitle = ViewBag.FacebookTitle ?? "My Default Title"; ViewBag.FacebookUrl = ViewBag.FacebookUrl ?? HttpContext.Current.Request.RawUrl; ViewBag.FacebookImage = ViewBag.FacebookImage ?? "http://www.mysite.com/images/logo_main.png"; ViewBag.FacebookDescription = ViewBag.FacebookDescription ?? "My Default Description"; }  2. Create an action filter and add it to all Controllers or your base controller. public class FacebookActionFilterAttribute : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { var viewBag = filterContext.Controller.ViewBag; viewBag.FacebookDescription = "My Actions Description"; viewBag.FacebookUrl = "My Full Url"; viewBag.FacebookTitle = "My Actions Title"; viewBag.FacebookImage = "My Actions Social Image"; base.OnActionExecuting(filterContext); } } Add attribute to your BaseController. [FacebookActionFilter] public class HomeController : Controller { .... }

• How to implement a component based system for items in a web game.

  - by Landstander

  Reading several other questions and answers on using a component based system to define items I want to use one for the items and spells in a web game written in PHP. I'm just stuck on the implementation. I'm going to use a DB schema suggested in this series (part 5 describes the schema); http://t-machine.org/index.php/2007/09/03/entity-systems-are-the-future-of-mmog-development-part-1/ This means I'll have an items table with generic item properties, a table listing all of the components for an item and finally records in each component table used to make up the item. Assuming I can select the first two together in a single query, I'm still going to do N queries for each component type. I'm kind of fine with this because I can cache the data into memcache and check there first before doing any queries. I'll need to build up the items on every request they are used in so the implementation needs to be on the lean side even if they're pulled from memcache. But right there is where I feel confident about implementing a component system for my items ends. I figure I'd need to bring attributes and behaviors into the container from each component it uses. I'm just not sure how to do that effectively and not end up writing a lot of specialized code to deal with each component. For example an AttackComponent might need to know how to filter targets inside of a battle context and also maybe provide an attack behavior. That same item might also have a UsableComponent which allows the item to be used and apply some effect onto a different set of targets filtered differently from the same battle context. Then not every part of an item is an active part, an AttributeBonusComponent might need to only kick in when the item is in an equipped state or when displaying the item details page. Ultimately, how should I bring all of the components together into the container so when I use an item as a weapon I get the correct list of targets? Know when a weapon can also be used as an item? Or to apply the bonuses the item provides to a character object? I feel like I've gone too far down the rabbit hole and I can't grasp onto the simple solution in front of me. (If that makes any sense at all.) Likewise if I were to implement the best answer from here I feel like I'd have a lot of the same questions. How to model multiple "uses" (e.g. weapon) for usable-inventory/object/items (e.g. katana) within a relational database.

• Lazy Processing of Streams

  - by Giorgio

  I have the following problem scenario: I have a text file and I have to read it and split it into lines. Some lines might need to be dropped (according to criteria that are not fixed). The lines that are not dropped must be parsed into some predefined records. Records that are not valid must be dropped. Duplicate records may exist and, in such a case, they are consecutive. If duplicate / multiple records exist, only one item should be kept. The remaining records should be grouped according to the value contained in one field; all records belonging to the same group appear one after another (e.g. AAAABBBBCCDEEEFF and so on). The records of each group should be numbered (1, 2, 3, 4, ...). For each group the numbering starts from 1. The records must then be saved somewhere / consumed in the same order as they were produced. I have to implement this in Java or C++. My first idea was to define functions / methods like: One method to get all the lines from the file. One method to filter out the unwanted lines. One method to parse the filtered lines into valid records. One method to remove duplicate records. One method to group records and number them. The problem is that the data I am going to read can be too big and might not fit into main memory: so I cannot just construct all these lists and apply my functions one after the other. On the other hand, I think I do not need to fit all the data in main memory at once because once a record has been consumed all its underlying data (basically the lines of text between the previous record and the current record, and the record itself) can be disposed of. With the little knowledge I have of Haskell I have immediately thought about some kind of lazy evaluation, in which instead of applying functions to lists that have been completely computed, I have different streams of data that are built on top of each other and, at each moment, only the needed portion of each stream is materialized in main memory. But I have to implement this in Java or C++. So my question is which design pattern or other technique can allow me to implement this lazy processing of streams in one of these languages.

• What exactly is a X-YMailISG header?

  - by iainH

  Finally ... our emails are being seen by Yahoo! not as junk anymore. Hurray! However I notice that the Yahoo! receiving MTA adds in a X-YMailISG header. It's very large ... 2**10 bits? Now that I've invested too large a chunk of my waking life in crafting our email headers I'm curious to know what an X-YMailISG header is. Can anybody tell me? Does it pose any security / authenticity issues? There's very little intelligible from Google results. Background: After many days tweaking TXT records in our domain's DNS zone file for SPF and DKIM, I have at last succeeded in generating email from our Drupal site that Yahoo! no longer marks as X-YahooFilteredBulk and the excellent service [email protected] returns results that show the emails passing SPF, DKIM and Sender-ID checks and appearing to SpamAssassin as ham. Yahoo! even adds a Received-SPF: pass header. Useful links: http://www.goldfisch.at/knowwiki/howtos/dkim-filter http://old.openspf.org/wizard.html Strangely enough the SPF TXT record needed / allowed a blank key / name field in our registrar's DNS management panel whereas the DKIM record needed the {selector}._domainkey as the key /name of the DKIM strings.

• SD Card reader not working on Sony Vaio

  - by TessellatingHeckler

  This laptop (Sony Vaio VGN-Z31MN/B PCG-6z2m) has been installed with Windows 7 64 bit, all the drivers from Sony's VAIO site are installed, and everything in Device Manager both (a) has a driver and (b) shows as working, no exclamation marks or warnings. "Hide empty drives" in Folder options is disabled so the card reader appears, but will not read the card ("please insert a disk in drive O:"). Previously, when the laptop had Windows XP on it, it could read the same card. Also, Windows update suggested driver ("SD Card Reader") doesn't work, Ricoh own drivers install properly but do the same behaviour. Other 3rd party driver suggestions from forums (Acer and Texas-Instruments FlashMedia) do not seem to install properly. I would post the PCI id if I had it, but it was just showing up as rimsptsk\diskricohmemorystickstorage (while it had the Ricoh Driver installed). Edit: If there are any lower level diagnostic utlities which might shed more light on it I'd welcome hearing of them. Anything which might show get it to put troubleshooting logs in the event log or identify chipsets or whatever...

• HOWTO: Disable complex password policy on Hyper-V Server 2008?

  - by Ian Boyd

  How do you disable the password complexity requirements on a Microsoft Hyper-V Server 2008 R2? Keep in mind that when you log into the server, the only UI you have is: And you cannot run gpedit.msc: C:\Users\Administrator>gpedit.msc 'gpedit.msc' is not recognized as an internal or external command, operable program or batch file. because there are no .msc snap-ins installed with Microsoft Hyper-V Server 2008 R2. The problem comes when you're trying to add an account to the server, so you can manage it, but it doesn't like most passwords: And, predictably, typing NET HELPMSG 2245 gives you The password does not meet the password policy requirements. Check the minimum p assword length, password complexity and password history requirements. i hoped it would have been a friendly user experience, and either: offered to disable the password policy tell me how to disable the password policy tell me how to check the minimum password length, password complexity and password history requirements. Password Complexity Requirements The Microsoft's default password complexity for Server Core is: Passwords cannot contain the user’s account name or parts of the user’s full name that exceed two consecutive characters. Passwords must be at least six characters in length. Passwords must contain characters from three of the following four categories: 1.English uppercase characters (A through Z). 2.English lowercase characters (a through z). 3.Base 10 digits (0 through 9). 4.Non-alphabetic characters (for example, !, $, #, %). External links Technet Forums: Hyper-V Server disable complex passwords Technet: Passwords must meet complexity requirements of the installed password filter Update: 2k views? So many people keep coming coming to it: up-vote it!

• Apache is reponding a blank white page

  I have the following situation: A site hosted in apache 2.4, with ssl, that works like a charm for a while now, but out of no where, without modifications to the site, apache started serving random blank pages.

• Mac OS X Server (10.5) mail trapped in queue

  - by Meltemi

  We've got mail accumulating in our Leopard Server's queue and not sure exactly why. This machine has required little maintenance over the years so I'm hoping someone here spot the obvious and save us some time. Let me know what other information would be helfull. Server appears to be functioning normally except for "clogged" queue and the following error associated with each "trapped" message: Looking at messages in the queue each one states something like this: Message ID: 4213C3B8B3F Date: October 27, 2009 11:33:27 AM Size: 1824 Sender: [email protected] Recipient(s) & Status: ---------------------- [email protected]: connect to 127.0.0.1[127.0.0.1]: Connection refused Under SettingsRelay we have checked Accept SMTP relays only from these hosts and networks: 127.0.0.0/8 10.0.1.0/24 The mail in queue is addressed to users whose accounts are on this server. Mail.app on the client appears to be functioning normally and checking checking mail on the server. We did add a virtual domain some time ago but all that was working fine for some time... This just started happening recently...any ideas? Edit: toggling the filter services on and off seems to have fixed this except for 2 remaining queued messages that show "mail transport unavailable" as an error!?!

• Query Execution Failed in Reporting Services reports

  - by Chris Herring

  I have some reporting services reports that talk to Analysis Services and at times they fail with the following error: An error occurred during client rendering.

• Per client DNS server assignment using Pfsense

  - by Trix

  I have a network where pfsense is the gateway. There are two sets of clients that I want. One where there will be some restrictions to the network (example, IM being blocked) and one network where there are no restrictions. One easy way I thought about doing this was assigning the different domains different DNS servers. One set could use OpenDNS, the other could use Google's Public DNS. The set with OpenDNS would have the filter options on (using OpenDNS' dashboard, I can check block IM .... so I do not manually need to block login.oscar.aol.com, meebo.com, gmail chat ....etc). So the problem is the DHCP server looks like it will only assign a single set of DNS servers to clients. Is there a way to set a per client assignment? Is there a better way to obtain what I want to obtain. This is just a small home network. I do not need anything fancy, but I do need this functionality in one way or another.

• Webmin / Virtualmin running php as www-data, is locked out of viewing .htaccess and writing

  - by Kirill

  I've asked this on the virtualmin forums, but haven't had any help from there. Recently, "something" happened and it seems that the apache service has gone a bit weird. What it does: it runs all apache traffic as www-data and sometimes spawns the php5-cgi process as www-data, this is a problem because all the domain users own their directories and default permissions don't let www-data write to these folders (file uploads are dead) or read .htaccess (permalinks are broken in wordpress). I've googled this for about a week straight now, tried pretty much everything I could find and achieved nothing. The only thing that I think might actually be the cause of all this is this page: http:// - i.imgur.com/NYW3x.png (got shut down by the spam filter) So I figured if I set it to "default", this might magically start working again, but all it does is "crash" apache (all websites timeout). I figure it's something to do with the "mpm" module or something, but I can't find anything relevant in the settings to modify for it to work. Can someone please point me in the right direction? System info: Webmin version 1.580 Kernel and CPU Linux 2.6.35.4-rscloud on x86_64 Virtualmin version 3.90.gpl GPL Ubuntu 10.04 LTS (Lucid) A couple screenshots of top http://i.imgur.com/U2DTK.png http://i.imgur.com/sNPKs.png

• DrayTek 2820 configuration using public IP addresses

  - by Kev

  I have a /29 range of public IP addresses assigned to me by my ISP. I'm trying to configure a SIP VOIP handset to register with my VOIP provider who recommend using public IP addresses rather than NAT. I have a DrayTek 2820 router flashed with the latest firmware and have configured my router as per DrayTek's FAQ at: How do I use a public subnet on the LAN (non-NAT operation ) ? My IP range is: xx.xx.94.16 -> xx.xx.94.23 This gives a usable range of: xx.xx.94.17 -> xx.xx.94.22 My router's public IP address is: xx.xx.94.17, the SIP VOIP handset is allocated xx.xx.94.18. I have a second internet connection and via that I can ping the handset. However for some reason I can't seem to get it to register with the provider. I tried adding a new Firewall filter to pass through from WAN to LAN: Source: ANY, Destination: xx.xx.94.18, UDP - Ports 1024 -> 65535 Out of interest I also tried opening port 80 to see if I could browse to the phone's admin web interface but no joy. I know that my ISP aren't blocking inbound service ports because I NAT Port Forwarded port 80 to one of my internal web servers and it rendered a test page I had set up. All the NAT settings are reset to factory defaults, i.e. there are no Port Redirection, DMZ Host, Open Ports or Address Mappings configured. The handset I'm using is a GrandStream GXP-2000. Is there anything else I should be doing?

• Make Thundirbird use and sync with Gmail Spam facility

  - by Senthil

  I am using Thundirbird 3.1.7. I am using Gmail with it. When I mark a message as spam in Thunderbird, I want it to go to Gmail's spam folder. But it is not happening. The mail is only marked as spam and stays in Gmail's inbox. How can I setup Thunderbird so that when I mark a message as spam in thundirbird, it goes to spam folder in both Thunderbird and Gmail? FYI: I have disabled Thunderbird's own adaptive spam controls so that it doesn't interfere. I am perfectly fine with Gmail's spam facility and don't want Thunderbird to add another layer of spam filtering. Still Thunderbird doesn't send emails to Gmail's spam. Update I figured that dragging and dropping the email to the spam folder in Thunderbird does the job. But is it the same as marking the email as spam in Gmail's interface? i.e. Gmail will do stuff when you mark an email as spam so that it can filter out similar messages in the future. Does it happen when I do this drag and drop thing too? Are they the same?

• Address (url) forwarding with Vyatta

  - by Trikks

  Hi Got this kind of noob question i suppose. I got this very basic network setup and need help to set up some address forwarding. As seen in my illustration below all traffic enters via the eth0 interface (85.123.32.23). The external dns is setup to direct all hosts to this ip as well. Now, how on earth do I filter the incoming requests to each box? The Ip's are static! Se the network layout here: http://vyatta.org/files/u11160/setup.png I do not wish to solve this by assigning tons of ports etc. In my wishful thinking something like this would be nice :) set service nat rule 10 type destination set service nat rule 10 inbound-interface eth0 set service nat rule 10 destination address ftp.myhost.com set service nat rule 10 inside-address address 192.168.100.20 This way ALL traffic to the address ftp.myhost.com (at eth0) should be routed to the internal ip, 192.168.100.20. Right, is there anyone who could point in some direction? Maybe it's wrong to use nat? Please help me! :)

• Ingress filtering in Linux traffic control: Redirect traffic to IFB device

  - by Dani Camps

  I have an openwrt router and I want to shape incoming traffic in order to classify all the traffic addressed to a certain IP address in my home network as low priority. For that purpose I want to redirect all traffic incoming to the eth1 interface, the one connected to the DSL modem, to an IFB device where I will do the shaping. These are the details of my system: Linux OpenWrt 2.6.32.27 #7 Fri Jul 15 02:43:34 CEST 2011 mips GNU/Linux Here is the script I am using where the last instruction is failing: # Variable definition ETH=eth1 IFB=ifb1 IP_LP="192.168.1.22/32" DL_RATE="900kbps" HP_RATE="890kbps" LP_RATE="10kbps" TC="tc" # Configuring the ifbX interface insmod ifb insmod sch_htb insmod sch_ingress ifconfig $IFB up # Adding the HTB scheduler to the ingress interface $TC qdisc add dev $IFB root handle 1: htb default 11 # Set the maximum bandwidth that each priority class can get, and the maximum borrowing they can do $TC class add dev $IFB parent 1:1 classid 1:10 htb rate $LP_RATE ceil $DL_RATE $TC class add dev $IFB parent 1:1 classid 1:11 htb rate $HP_RATE ceil $DL_RATE # Redirect all ingress traffic arriving at $ETH to $IFB $TC qdisc del dev $ETH ingress 2>/dev/null $TC qdisc add dev $ETH ingress $TC filter add dev $ETH parent ffff: protocol ip prio 1 u32 \ match u32 0 0 flowid 1:1 \ action mirred egress redirect dev $IFB The last instruction fails with: Action 4 device ifb1 ifindex 9 RTNETLINK answers: No such file or directory We have an error talking to the kernel Does anyone know what am I doing wrong ?

• exim4 - disable autoreplies about "SMTP error from remote mail server after RCPT"

  - by osgx

  Hello I have a setup of exim4 on domain1 in front of other server, domain2 (with sendmail). Second server have no direct access to internet, so domain1 is MX for domain2. And domain2 is set as hubbed_host in the exim4 on domain1. When spammer sends message for no_such_user@domain2, its sendmail do a reject: 550 5.1.1 <no_such_user@domain2>... User unknown Then, exim4 at domain1 do an auto-reply like this: This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: no_such_user@domain2 SMTP error from remote mail server after RCPT TO:<no_such_user@domain2>: host 10.0.0.1 [10.0.0.1]: 550 5.1.1 <no_such_user@domain2>... User unknown The spammers uses fake "from" field, and such generated messages are frozen by exim for a long time. How can I disable some or all autoreplies from exim4? Ideally, I want a filter, if message was not delivered with error "User unknown" than don't generate any autoreply from mailer-daemon. Thanks!

• Windows Server 2008 DHCP with RRAS

  - by Guillermo Prandi

  I have a Windows Server 2008 R2 which is a member of a domain, but is placed in a remote location. The server is directly connected to Internet. Clients need to access a particular insecure TCP service in this server (ports 9730 and 9731). Since clients have dynamic IP addresses I cannot know in advance, I thought it would be nice to have them connected through a VPN in order to access the insecure service, but ONLY to access that service, like this: Client ------> VPN TUNNEL ------> (Insecure service at Server) | \----> (Normal internet access) I'd enable the insecure ports in the firewall only from VPN accesses. For this I configured RRAS in the server and gave it a static IP address range (172.19.1.2 through 172.19.1.254) to serve the clients. First I thought I could use DHCP to assign the addresses, but I cannot use DHCP in my LAN connection (not allowed by the hosting service). I tried configuring DHCP binding it to a Microsoft Loopback Adapter, but that's not supported as a DHCP source by RRAS. What I want to accomplish is to send specific DHCP options to the client (network mask, routing table, etc.). In particular: Prevent the client from having the server as default router (without changing the client's "use default gateway in remote network"). Have it as a route for the server's internal RRAS address only (172.19.1.1). Prevent the client from using a 255.255.0.0 mask for the 172.19.x.x network (a 255.255.255.0 mask would be better). Can I do that with RRAS only? How? Currently, the only solution I can think of is to use DHCP in the LAN adapter, but filter DHCP packets so they don't reach the provider's network. However, I'm not sure if that will work. Any suggestions are welcomed! Guille

• Apache mod-pagespeed installation affects mod-spdy?

  - by tim peterson

  Recently my site (an https connection, running on an Amazon EC2 ubuntu apache2.2) has this issue where I need to load the page several times (3-4) before it will load normally without issue. It will then load normally as long as I keep loading pages regularly (every couple seconds). It will stall again if I don't load pages for a few minutes. It has nothing to do with my application because I don't have this problem with the exact same app codebase on my Apache installation on my laptop. The only things to my knowledge that I've changed is that I recently installed mod_spdy and then a few weeks later I installed mod_pagespeed, https://developers.google.com/speed/pagespeed/mod. However, I have since turned mod_pagespeed off by setting its pagespeed.conf to mod_pagespeed off. Unfortunately, that didn't solve the problem. The line below is how every of last 10 lines of my error.log look: # tail -f /var/log/apache2/error.log ... [32728:32729:ERROR:mod_spdy.cc(162)] request->chunked == 1 in request GET / HTTP/1.1 [Sat Jun 02 04:50:08 2012] [warn] [client 50.136.93.153] [stream 5] [32728:32729:WARNING:http_to_spdy_filter.cc(113)] HttpToSpdyFilter is not the last filter in the chain: chunk any thoughts? thank you, tim

• Endian Destination NAT

  - by Ben Swinburne

  I have installed Endian Community Firewall 2.3 and am clearly misunderstanding/doing something wrong with it. I'm trying to create some destination NAT rules to allow incoming connections to various services within the network. Router - RED I/F - x.x.x.x Router - GREEN I/F - 192.168.11.253 ECF - RED I/F - 192.168.11.254/24 ECF - GREEN I/F - 192.168.12.254/24 Target server - 192.168.12.1 Please ignore the haphazard choice of subnets and addresses- I'm trying to quickly plop Endian into an existing network before a complete rework in 6-12 months so for now. Everything works except destination NAT, so outgoing connections are fine, the routes between the two subnets are OK etc. I want to create various incoming NATs but let's take for the sake of argument, SMTP port 25 from the Internet to Target server 192.168.12.1. I've tried almost every combination of options in the Destination NAT section to achieve this and clearly am doing something wrong. I suspect my confusion must be somewhere in the Access From and/or Target section. The rest seems OK Filter Policy = Allow Service = SMTP Protocol = TCP Port = 25 Translate to type = IP DNAT Policy = NAT Insert IP = 192.168.12.1 Port Range = 25 Enabled = Checked Position = First I can't work out what I'm doing wrong, or am I doing it right and it's just not working!? Any help would be greatly appreciated.
