• Inbound SIP calls through Cisco 881 NAT hang up after a few seconds

  - by MasterRoot24

  I've recently moved to a Cisco 881 router for my WAN link. I was previously using a Cisco Linksys WAG320N as my modem/router/WiFi AP/NAT firewall. The WAG320N is now running in bridged mode, so it's simply acting as a modem with one of it's LAN ports connected to FE4 WAN on my Cisco 881. The Cisco 881 get's a DHCP provided IP from my ISP. My LAN is part of default Vlan 1 (192.168.1.0/24). General internet connectivity is working great, I've managed to setup static NAT rules for my HTTP/HTTPS/SMTP/etc. services which are running on my LAN. I don't know whether it's worth mentioning that I've opted to use NVI NAT (ip nat enable as opposed to the traditional ip nat outside/ip nat inside) setup. My reason for this is that NVI allows NAT loopback from my LAN to the WAN IP and back in to the necessary server on the LAN. I run an Asterisk 1.8 PBX on my LAN, which connects to a SIP provider on the internet. Both inbound and outbound calls through the old setup (WAG320N providing routing/NAT) worked fine. However, since moving to the Cisco 881, inbound calls drop after around 10 seconds, whereas outbound calls work fine. The following message is logged on my Asterisk PBX: [Dec 9 15:27:45] WARNING[27734]: chan_sip.c:3641 retrans_pkt: Retransmission timeout reached on transmission [email protected] for seqno 1 (Critical Response) -- See https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions Packet timed out after 6528ms with no response [Dec 9 15:27:45] WARNING[27734]: chan_sip.c:3670 retrans_pkt: Hanging up call [email protected] - no reply to our critical packet (see https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions). (I know that this is quite a common issue - I've spend the best part of 2 days solid on this, trawling Google.) I've done as I am told and checked https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions. Referring to the section "Other SIP requests" in the page linked above, I believe that the hangup to be caused by the ACK from my SIP provider not being passed back through NAT to Asterisk on my PBX. I tried to ascertain this by dumping the packets on my WAN interface on the 881. I managed to obtain a PCAP dump of packets in/out of my WAN interface. Here's an example of an ACK being reveived by the router from my provider: 689 21.219999 193.x.x.x 188.x.x.x SIP 502 Request: ACK sip:[email protected] | However a SIP trace on the Asterisk server show's that there are no ACK's received in response to the 200 OK from my PBX: http://pastebin.com/wwHpLPPz In the past, I have been strongly advised to disable any sort of SIP ALGs on routers and/or firewalls and the many posts regarding this issue on the internet seem to support this. However, I believe on Cisco IOS, the config command to disable SIP ALG is no ip nat service sip udp port 5060 however, this doesn't appear to help the situation. To confirm that config setting is set: Router1#show running-config | include sip no ip nat service sip udp port 5060 Another interesting twist: for a short period of time, I tried another provider. Luckily, my trial account with them is still available, so I reverted my Asterisk config back to the revision before I integrated with my current provider. I then dialled in to the DDI associated with the trial trunk and the call didn't get hung up and I didn't get the error above! To me, this points at the provider, however I know, like all providers do, will say "There's no issues with our SIP proxies - it's your firewall." I'm tempted to agree with this, as this issue was not apparent with the old WAG320N router when it was doing the NAT'ing. I'm sure you'll want to see my running-config too: ! !

• Serving images from another hostname vs Apache overload for the rewrites

  - by luison

  We are trying to improve further the speed of some sites with older HTML in order as well to obtain better SEO results. We have now applied some minify measures, combined html, css etc. We use a small virtualized infrastructure and we've always wanted to use a light + standar http server configuration so the first one can serve images and static contents vs the other one php, rewrites, etc. We can easily do that now with a VM using the same files and conf of vhosts (bind mounts) on apache but with hardly any modules loaded. This means the light httpd will have smaller fingerprint that would allow us to serve more and quicker, have more minSpareServer running, etc. So, as browsers benefit from loading static content from different hostnames as well, we've thought about building a rewrite rule on our main server (main.com) to "redirect" all images and css *.jpg, *.gif, *.css etc to the same at say cdn.main.com thus the browser being able to have more connections. The question is, assuming we have a very complex rewrite ruleset already (we manually manipulate many old URLs for SEO) will it be worth? I mean will the additional load of main's apache to have to redirect main.com/image.jpg (I understand we'll have to do a 301) to cdn.main.com/image.jpg + then cdn.main.com having to serve it, be larger than the gain we would be archiving on the browser? Could the excess of 301s of all images on a page be penalized by google? How do large companies work this out, does the original code already include images linked from the cdn with absolute paths? EDIT Just to clarify, our concern is not to do so much with server performance or bandwith. We could obviously employ an external CDN server but we have plenty CPU and bandwith. Our concern is with how to have "old" sites with plenty semi-static HTML content benefiting from splitting connections for images and static content via apache without having to change the html to absolute paths (ie. image.jpg to cdn.main.com/image.jpg happening on the server not the code)

• Apache is sending php files to my browser instead of parsing

  I have to set up PHP on an existing web host.

• NAT ports - how do they work?

  - by Davidoper

  I have the following network schema: Computer A: three nics: NIC 1 (eth0): dhcp, public internet NIC 2 (eth1): static 192.168.1.1, gateway for Computer B NIC 3 (eth2): static 192.168.2.1, gateway for Computer C Computer B: static 192.168.1.2, using gateway 192.168.1.1 (NIC 2). Computer C: static 192.168.2.2, using gateway 192.168.2.1 (NIC 3). So I applied this to get NAT working: iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE Every computer can connect to the internet now. I have been applying rules to the main computer (Computer A), like dropping connections to some ports, e.g ssh: iptables -A INPUT -p tcp --dport 22 -j DROP But for instance, now I would like only allow connections for ports 20,21,22,53 and 80 in Computer C, and ignore the outside traffic if it's not related to those ports. The allowed connections should be FROM Computer C to outside, but not from outside to Computer C (I mean - Computer C is not hosting any HTTP or SSH, but it is going to use them as a client). I guess this sould be done like this: iptables -A OUTPUT -i eth2 -o eth0 -p tcp --dport 21 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A INPUT -i eth2 -o eth0 -p tcp --sport 21 -m state --state ESTABLISHED -j ACCEPT The last rule (dropping any other traffic different from those) is at the end of the configuration, so -A should be working correctly. The thing is... it is not working. If I put the last rule like this: iptables -A FORWARD -i eth2 -o eth0 -j DROP It just drops everything and, for instance, port 21 (previously opened as you can see above) is not either working. Can you tell me what could I have done wrong? I have been struggling with this problem for some time and I am unable to solve it. Thanks!

• New router messed up server 2003 setup...

  - by Aceth

  Hey, We were sent a new 2wire router today configured it as best we can to match the old bt voyager. We've also got X static IP's. We've manage to get our webserver on one of the new IP's public facing. then we use a hardware firewall which is in a DMZ again with a different static IP. This firewall then is our gateway for our internal LAN. with a few servers etc. The problem we're having is only our PDC (primary Domain controller which has exchange 2003 on) can't ping externally even an external IP. We've connected laptops to the 2wire router and obtain a private ip 192.168.1.X and it works fine can ping etc. our other servers with an internal ip behind the firewall can ping out fine. We've connected to the firewalls logging console and the pings from the server are allowed through so its fine there. The server in question is a Windows server 2003 R2 Enterprise SP2 + Exchange 2003 Server doesn't have firewall turned on. it has static private IP .. gateway is pointing to the right one External Static IP is routing fine inwards We've ran out of ideas .. help??

• Installing/enabling PHP Pecl Intl extension on CentOs 5

  - by Marijn Huizendveld

  Original question: I'm having trouble installing the PHP Pecl Intl extension on my CentOs 5 machine. After installing both icu and libicu with the following commands: $ yum install icu $ yum install libicu I tried to install the Intl extension like so: $ /usr/bin/pecl install intl I selected to search for the default location for the ICU libraries and header files. It ends up crashing like this: checking whether to enable internationalization support... yes, shared checking for icu-config... no checking for location of ICU headers and libraries... not found configure: error: Unable to detect ICU prefix or no failed. Please verify ICU install prefix and make sure icu-config works. ERROR: `/tmp/pear/temp/intl/configure --with-icu-dir=DEFAULT' failed update After successfully installing the development version of icu as suggested by RusAlex (thanks RusAlex) like so: $ yum install libicu-devel I ran into a new problem which I also encountered locally the following command: $ /usr/bin/pecl install intl now produces this error: /private/tmp/pear/temp/intl/collator/collator_class.c:92: error: duplicate 'static' /private/tmp/pear/temp/intl/collator/collator_class.c:96: error: duplicate 'static' /private/tmp/pear/temp/intl/collator/collator_class.c:101: error: duplicate 'static' /private/tmp/pear/temp/intl/collator/collator_class.c:107: error: duplicate 'static' make: *** [collator/collator_class.lo] Error 1 ERROR: `make' failed It appears to have something to do with PHP 5.3 being bundled with Intl already. But how can I enable this extension, if I look in my PHP Info than I cannot find any reference to it...

• rc scripts dependencies

  - by chris

  On a Ubuntu 10.04.1 LTS server install certain services fail to start properly after a reboot. I have a couple of virtual interfaces defined on eth0: /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 172.16.5.240 netmask 255.255.255.0 gateway 172.16.5.1 auto eth0:1 iface eth0:1 inet static address 172.16.5.241 netmask 255.255.255.0 gateway 172.16.5.1 auto eth0:2 iface eth0:2 inet static address 172.16.5.242 netmask 255.255.255.0 gateway 172.16.5.1 auto eth0:3 iface eth0:3 inet static address 172.16.5.243 netmask 255.255.255.0 gateway 172.16.5.1 and so on... The services that try to bind to for example 172.16.5.243 fail during boot, complaining that there is no such IP address. My questions: 1) Are the services started parallel by default? Can I disable that so they run sequentially? 2) Is there a way to define dependencies between rc scripts? I'm only familiar with the defining the order of seqentially started scripts using the numbers in /etc/rc[0-6].d/) Any other fix or workaround appreciated.

• Apache22 on FreeBSD - Starts, does not respond to requests

  - by NuclearDog

  Hey folks! I'm running Apache 2.2.17 with the peruser MPM on FreeBSD 8.2-RC1 on Amazon's EC2 (so it's XEN). It was installed from ports. My problem is that, although Apache is running, listening for, and accepting connections, it doesn't actually respond to any or show them in the log at all. If I telnet to the port it's listening on and type out an HTTP request: GET / HTTP/1.1 Host: asdfasdf And hit enter a couple of times, it just sits there... Nothing. No response requesting with a browser either. There doesn't appear to be anything helpful in the error log: [Sun Jan 09 16:56:24 2011] [warn] Init: Session Cache is not configured [hint: SSLSessionCache] [Sun Jan 09 16:56:25 2011] [notice] Digest: generating secret for digest authentication ...

I also tried uninstalling apache22-peruser-mpm and just installing straight apache22... Still no luck. I tried removing all of the LoadModule lines from httpd.conf and just re-enabled the ones that were necessary to parse the config. Ended up with only the following loaded: root:/usr/local/etc/apache22# /usr/local/sbin/apachectl -M Loaded Modules: core_module (static) mpm_peruser_module (static) http_module (static) so_module (static) authz_host_module (shared) log_config_module (shared) alias_module (shared) Syntax OK root:/usr/local/etc/apache22# Same results.

Does anyone have any idea what's going on? Why it would be doing this? I've exhausted all of my debugging expertise. :/ Thanks for any suggestions!

• Windows Server 2008 R2 Virtual Network Setup

  - by jpearl01

  Hi all, Some background: I'm very much new to networking in general, and virtualization in particular. I'm trying to set up a series of VMs as we are transitioning to a thin client setup. I have been supplied a limited number of static ip addresses. The server is located in an offsite building which houses the network we use to connect to the internet, share folders etc. The setup I've been trying to go for is this: The host OS (Windows Server 2008 R2) is bound to one nic using one of the static ips (say, Nic1 and ip 10.255.6.61). I've set up another external virtual network attached to another physical nic , and a virtual private network attached to no nic. There is one VM running the same os (as the host). This VM is connected to both the external virtual network (and uses another static ip say Nic2 and ip 10.255.6.62) and also to the virtual private network (I gave it a static random ip 192.168.88.1 subnet mask 255.255.255.0). This virtual private network is connected to all the other VMs. I'd like to share the internet connection with all the other VMs on the private virtual network, and so I installed the RRAS role on the server connected to Nic2, and selected the option to share the internet over the vpn. I've run through the RRAS wizard a few times, trying different configurations, but none of them seem to be letting the other vms connect to the 'net. The vms seem to connect to the virtual private network fine, they are assigned an ip address and everything, but no internet, and no rest of the network either. The other problem is in general I connect to the vms with RDP. Will that be possible with a setup like this? i.e. will the vms show up as computers on the network? If not, what are my other options? Thanks! ~josh

• Routing / binding 128 IPs to one server

  - by Andrew

  I have a Ubuntu server with 128 ip's (static external ips 86.xx.xx.16), and I want to crawl pages thru different ip's. The gateway is xx.xxx.xxx.1, the main ip is xx.xxx.xxx.16, and the other 128 ip's are xx.xxx.xxx.129/255. I tried this configuration in /etc/network/interfaces but I doesn't work. It work if I remove the gateway for the aliases eth0:0 and eth0:1. I think this is routing problem. auto lo iface lo inet loopback auto eth0 auto eth0:0 auto eth0:1 iface eth0 inet static address xx.xxx.xxx.16 netmask 255.255.255.128 gateway xx.xxx.xxx.1 iface eth0:0 inet static address xx.xxx.xxx.129 netmask 255.255.255.128 gateway xx.xxx.xxx.1 iface eth0:1 inet static address xx.xxx.xxx.130 netmask 255.255.255.128 gateway xx.xxx.xxx.1 Also, please tell me how to "reset" every changes that I made in networking and routing. Update: I removed the gateway and now it works. I can reach the website thru all 128 ip's. But when I try to bind a socket connection in php to a specific ip I get no answer. socket_bind($sock, "xx.xxx.xx.xxx"); socket_connect($sock, 'google.com', 80); I tryed to use a sniffer to see the packets, and I see the packet sent from binded ip to google.com but the "connection" can't be established. I don't know anything about "route" command, but I have a feeling that this is the solution.

• Virtual IPv6 Network between VirtualBox VMs

  - by Ben

  I'm trying to create a virtual IPv6 network as a test environment. I have 5 VirtualBox VMs (Ubuntu Server) with network adapters using host-only networking. You can imagine them being connected in series and every machine connects 2 subnets. I want to ping the last machine from the first one: On: 2001:db8:aaaa::100 I want to ping 2001:db8:dddd::101 (Note: there is no cccc network in between) Only static configuration and routes are used: /etc/network/interfaces auto eth0 iface eth0 inet6 static address 2001:db8:aaaa::100 netmask 64 /etc/network/interfaces auto eth0 iface eth0 inet6 static address 2001:db8:aaaa::101 netmask 64 auto eth1 iface eth1 inet6 static address 2001:db8:bbbb::100 netmask 64 up ip -6 route add 2001:db8:dddd::/64 via 2001:db8:bbbb::101 dev eth1 down ip -6 route del 2001:db8:dddd::/64 via 2001:db8:bbbb::101 dev eth1 I thought there might be some automatic route discovery going on. Anyway, ping6 2001:db8:dddd::100 will not work from aaaa::100 When I add the route: ip -6 route add 2001:db8:dddd::/64 via 2001:db8:aaaa::101 it will work. But the next interface in the same network dddd::101 is not reachable. How could that be? There is a machine with an interface bbbb::101 and another dddd::100 and I can ping the latter one, but the machine connected to it, dddd::101 not?? I also have also turned on forwarding. Any ideas?

• pfSense routing between two routers with shared network

  - by JohnCC

  I have a network set-up using two pfSense routers arranged like this:- DMZ1 WAN1 WAN2 DMZ2 | | | | | | | | \___ PF1 PF2___/ | | | | \___TRUSTED___/ Each pfSense router has its own separate WAN connection, and a separate DMZ network attached to it. They share a common TRUSTED LAN between them. The machines on the trusted network have PF1 as their default gateway. PF1 has a static route defined to DMZ2 via PF2, and PF2 has a static route to DMZ1 via PF1. There is NAT to the WAN but internal networks (DMZ1/2 and TRUSTED) use different RFC1918 subnets. I inherited this arrangement, and all used to work fine. I made a config change to PF1 (relating to multicast), and machines on DMZ2 suddenly could not talk to TRUSTED. I rolled the change back, but the problem persisted. What I guess you'd hope would happen is that TCP packets would go DMZ2 - PF2 - TRUSTED and on return TRUSTED - PF1 - PF2 - DMZ2. That's the only way I can see it would have worked. However, PF1 drops the returning packets. I've verified this using tcpdump. I've worked around this by adding static routes to DMZ2 via PF2 to the servers on TRUSTED, but some devices on there do not support static routes so this is not ideal. Is there way to make this arrangement work decently, or is the design inherently flawed? Thanks!

• Profile System: User share the same id

  - by Malcolm Frexner

  I have a strange effect on my site when it is under heavy load. I randomly get the properties of other users settings. I have my own implementation of the profile system so I guess I can not blame the profile system itself. I just need a point to start debugging from. I guess there is a cookie-value that maps to an Profile entry somewhere. Is there any chance to see how this mapping works?

• Using C# 4.0’s DynamicObject as a Stored Procedure Wrapper

  - by EltonStoneman

  [Source: http://geekswithblogs.net/EltonStoneman] Overview Ignoring the fashion, I still make a lot of use of DALs – typically when inheriting a codebase with an established database schema which is full of tried and trusted stored procedures. In the DAL a collection of base classes have all the scaffolding, so the usual pattern is to create a wrapper class for each stored procedure, giving typesafe access to parameter values and output. DAL calls then looks like instantiate wrapper-populate parameters-execute call:       using (var sp = new uspGetManagerEmployees())     {         sp.ManagerID = 16;         using (var reader = sp.Execute())         {             //map entities from the output         }     }   Or rolling it all into a fluent DAL call – which is nicer to read and implicitly disposes the resources:   This is fine, the wrapper classes are very simple to handwrite or generate. But as the codebase grows, you end up with a proliferation of very small wrapper classes: The wrappers don't add much other than encapsulating the stored procedure call and giving you typesafety for the parameters. With the dynamic extension in .NET 4.0 you have the option to build a single wrapper class, and get rid of the one-to-one stored procedure to wrapper class mapping. In the dynamic version, the call looks like this:       dynamic getUser = new DynamicSqlStoredProcedure("uspGetManagerEmployees", Database.AdventureWorks);     getUser.ManagerID = 16;       var employees = Fluently.Load<List<Employee>>()                             .With<EmployeeMap>()                             .From(getUser);   The important difference is that the ManagerId property doesn't exist in the DynamicSqlStoredProcedure class. Declaring the getUser object with the dynamic keyword allows you to dynamically add properties, and the DynamicSqlStoredProcedure class intercepts when properties are added and builds them as stored procedure parameters. When getUser.ManagerId = 16 is executed, the base class adds a parameter call (using the convention that parameter name is the property name prefixed by "@"), specifying the correct SQL Server data type (mapping it from the type of the value the property is set to), and setting the parameter value. Code Sample This is worked through in a sample project on github – Dynamic Stored Procedure Sample – which also includes a static version of the wrapper for comparison. (I'll upload this to the MSDN Code Gallery once my account has been resurrected). Points worth noting are: DynamicSP.Data – database-independent DAL that has all the data plumbing code. DynamicSP.Data.SqlServer – SQL Server DAL, thin layer on top of the generic DAL which adds SQL Server specific classes. Includes the DynamicSqlStoredProcedure base class. DynamicSqlStoredProcedure.TrySetMember. Invoked when a dynamic member is added. Assumes the property is a parameter named after the SP parameter name and infers the SqlDbType from the framework type. Adds a parameter to the internal stored procedure wrapper and sets its value. uspGetManagerEmployees – the static version of the wrapper. uspGetManagerEmployeesTest – test fixture which shows usage of the static and dynamic stored procedure wrappers. The sample uses stored procedures from the AdventureWorks database in the SQL Server 2008 Sample Databases. Discussion For this scenario, the dynamic option is very favourable. Assuming your DAL is itself wrapped by a higher layer, the stored procedure wrapper classes have very little reuse. Even if you're codegening the classes and test fixtures, it's still additional effort for very little value. The main consideration with dynamic classes is that the compiler ignores all the members you use, and evaluation only happens at runtime. In this case where scope is strictly limited that's not an issue – but you're relying on automated tests rather than the compiler to find errors, but that should just encourage better test coverage. Also you can codegen the dynamic calls at a higher level. Performance may be a consideration, as there is a first-time-use overhead when the dynamic members of an object are bound. For a single run, the dynamic wrapper took 0.2 seconds longer than the static wrapper. The framework does a good job of caching the effort though, so for 1,000 calls the dynamc version still only takes 0.2 seconds longer than the static: You don't get IntelliSense on dynamic objects, even for the declared members of the base class, and if you've been using class names as keys for configuration settings, you'll lose that option if you move to dynamics. The approach may make code more difficult to read, as you can't navigate through dynamic members, but you do still get full debugging support.     var employees = Fluently.Load<List<Employee>>()                             .With<EmployeeMap>()                             .From<uspGetManagerEmployees>                             (                                 i => i.ManagerID = 16,                                 x => x.Execute()                             );

  WebResources in ASP.NET are pretty useful feature. WebResources are resources that are embedded into a .NET assembly and can be loaded from the assembly via a special resource URL. WebForms includes a method on the ClientScriptManager (Page.ClientScript) and the ScriptManager object to retrieve URLs to these resources. For example you can do: ClientScript.GetWebResourceUrl(typeof(ControlResources), ControlResources.JQUERY_SCRIPT_RESOURCE); GetWebResourceUrl requires a type (which is used for the assembly lookup in which to find the resource) and the resource id to lookup. GetWebResourceUrl() then returns a nasty old long URL like this: WebResource.axd?d=-b6oWzgbpGb8uTaHDrCMv59VSmGhilZP5_T_B8anpGx7X-PmW_1eu1KoHDvox-XHqA1EEb-Tl2YAP3bBeebGN65tv-7-yAimtG4ZnoWH633pExpJor8Qp1aKbk-KQWSoNfRC7rQJHXVP4tC0reYzVw2&t=634533278261362212 While lately excessive resource usage has been frowned upon especially by MVC developers who tend to opt for content distributed as files, I still think that Web Resources have their place even in non-WebForms applications. Also if you have existing assemblies that include resources like scripts and common image links it sure would be nice to access them from non-WebForms pages like MVC views or even in plain old Razor Web Pages. Where's my Page object Dude? Unfortunately natively ASP.NET doesn't have a mechanism for retrieving WebResource Urls outside of the WebForms engine. It's a feature that's specifically baked into WebForms and that relies specifically on the Page HttpHandler implementation. Both Page.ClientScript (obviously) and ScriptManager rely on a hosting Page object in order to work and the various methods off these objects require control instances passed. The reason for this is that the script managers can inject scripts and links into Page content (think RegisterXXXX methods) and for that a Page instance is required. However, for many other methods - like GetWebResourceUrl() - that simply return resources or resource links the Page reference is really irrelevant. While there's a separate ClientScriptManager class, it's marked as sealed and doesn't have any public constructors so you can't create your own instance (without Reflection). Even if it did the internal constructor it does have requires a Page reference. No good… So, can we get access to a WebResourceUrl generically without running in a WebForms Page instance? We just have to create a Page instance ourselves and use it internally. There's nothing intrinsic about the use of the Page class in ClientScript, at least for retrieving resources and resource Urls so it's easy to create an instance of a Page for example in a static method. For our needs of retrieving ResourceUrls or even actually retrieving script resources we can use a canned, non-configured Page instance we create on our own. The following works just fine: public static string GetWebResourceUrl(Type type, string resource ) { Page page = new Page(); return page.ClientScript.GetWebResourceUrl(type, resource); } A slight optimization for this might be to cache the created Page instance. Page tends to be a pretty heavy object to create each time a URL is required so you might want to cache the instance: public class WebUtils { private static Page CachedPage { get { if (_CachedPage == null) _CachedPage = new Page(); return _CachedPage; } } private static Page _CachedPage; public static string GetWebResourceUrl(Type type, string resource) { return CachedPage.ClientScript.GetWebResourceUrl(type, resource); } } You can now use GetWebResourceUrl in a Razor page like this: <!DOCTYPE html> <html <head> <script src="@WebUtils.GetWebResourceUrl(typeof(ControlResources),ControlResources.JQUERY_SCRIPT_RESOURCE)"> </script> </head> <body> <div class="errordisplay"> <img src="@WebUtils.GetWebResourceUrl(typeof(ControlResources),ControlResources.WARNING_ICON_RESOURCE)" /> This is only a Test! </div> </body> </html> And voila - there you have WebResources served from a non-Page based application. WebResources may be a on the way out, but legacy apps have them embedded and for some situations, like fallback scripts and some common image resources I still like to use them. Being able to use them from non-WebForms applications should have been built into the core ASP.NETplatform IMHO, but seeing that it's not this workaround is easy enough to implement.© Rick Strahl, West Wind Technologies, 2005-2011Posted in ASP.NET  MVC   Tweet (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• TDD and WCF behavior

  - by Frederic Hautecoeur

  Some weeks ago I wanted to develop a WCF behavior using TDD. I have lost some time trying to use mocks. After a while i decided to just use a host and a client. I don’t like this approach but so far I haven’t found a good and fast solution to use Unit Test for testing a WCF behavior. To Implement my solution I had to : Create a Dummy Service Definition; Create the Dummy Service Implementation; Create a host; Create a client in my test; Create and Add the behavior; Dummy Service Definition This is just a simple service, composed of an Interface and a simple implementation. The structure is aimed to be easily customizable for my future needs.   Using Clauses : 1: using System.Runtime.Serialization; 2: using System.ServiceModel; 3: using System.ServiceModel.Channels; The DataContract: 1: [DataContract()] 2: public class MyMessage 3: { 4: [DataMember()] 5: public string MessageString; 6: } The request MessageContract: 1: [MessageContract()] 2: public class RequestMessage 3: { 4: [MessageHeader(Name = "MyHeader", Namespace = "http://dummyservice/header", Relay = true)] 5: public string myHeader; 6:  7: [MessageBodyMember()] 8: public MyMessage myRequest; 9: } The response MessageContract: 1: [MessageContract()] 2: public class ResponseMessage 3: { 4: [MessageHeader(Name = "MyHeader", Namespace = "http://dummyservice/header", Relay = true)] 5: public string myHeader; 6:  7: [MessageBodyMember()] 8: public MyMessage myResponse; 9: } The ServiceContract: 1: [ServiceContract(Name="DummyService", Namespace="http://dummyservice",SessionMode=SessionMode.Allowed )] 2: interface IDummyService 3: { 4: [OperationContract(Action="Perform", IsOneWay=false, ProtectionLevel=System.Net.Security.ProtectionLevel.None )] 5: ResponseMessage DoThis(RequestMessage request); 6: } Dummy Service Implementation 1: public class DummyService:IDummyService 2: { 3: #region IDummyService Members 4: public ResponseMessage DoThis(RequestMessage request) 5: { 6: ResponseMessage response = new ResponseMessage(); 7: response.myHeader = "Response"; 8: response.myResponse = new MyMessage(); 9: response.myResponse.MessageString = 10: string.Format("Header:<{0}> and Request was <{1}>", 11: request.myHeader, request.myRequest.MessageString); 12: return response; 13: } 14: #endregion 15: } Host Creation The most simple host implementation using a Named Pipe binding. The GetBinding method will create a binding for the host and can be used to create the same binding for the client. 1: public static class TestHost 2: { 3: 4: internal static string hostUri = "net.pipe://localhost/dummy"; 5:  6: // Create Host method. 7: internal static ServiceHost CreateHost() 8: { 9: ServiceHost host = new ServiceHost(typeof(DummyService)); 10:  11: // Creating Endpoint 12: Uri namedPipeAddress = new Uri(hostUri); 13: host.AddServiceEndpoint(typeof(IDummyService), GetBinding(), namedPipeAddress); 14:  15: return host; 16: } 17:  18: // Binding Creation method. 19: internal static Binding GetBinding() 20: { 21: NamedPipeTransportBindingElement namedPipeTransport = new NamedPipeTransportBindingElement(); 22: TextMessageEncodingBindingElement textEncoding = new TextMessageEncodingBindingElement(); 23:  24: return new CustomBinding(textEncoding, namedPipeTransport); 25: } 26:  27: // Close Method. 28: internal static void Close(ServiceHost host) 29: { 30: if (null != host) 31: { 32: host.Close(); 33: host = null; 34: } 35: } 36: } Checking the service A simple test tool check the plumbing. 1: [TestMethod] 2: public void TestService() 3: { 4: using (ServiceHost host = TestHost.CreateHost()) 5: { 6: host.Open(); 7:  8: using (ChannelFactory<IDummyService> channel = 9: new ChannelFactory<IDummyService>(TestHost.GetBinding() 10: , new EndpointAddress(TestHost.hostUri))) 11: { 12: IDummyService svc = channel.CreateChannel(); 13: try 14: { 15: RequestMessage request = new RequestMessage(); 16: request.myHeader = Guid.NewGuid().ToString(); 17: request.myRequest = new MyMessage(); 18: request.myRequest.MessageString = "I want some beer."; 19:  20: ResponseMessage response = svc.DoThis(request); 21: } 22: catch (Exception ex) 23: { 24: Assert.Fail(ex.Message); 25: } 26: } 27: host.Close(); 28: } 29: } Running the service should show that the client and the host are running fine. So far so good. Adding the Behavior Add a reference to the Behavior project and add the using entry in the test class. We just need to add the behavior to the service host : 1: [TestMethod] 2: public void TestService() 3: { 4: using (ServiceHost host = TestHost.CreateHost()) 5: { 6: host.Description.Behaviors.Add(new MyBehavior()); 7: host.Open();¨ 8: …  If you set a breakpoint in your behavior and run the test in debug mode, you will hit the breakpoint. In this case I used a ServiceBehavior. To add an Endpoint behavior you have to add it to the endpoints. 1: host.Description.Endpoints[0].Behaviors.Add(new MyEndpointBehavior()) To add a contract or an operation behavior a custom attribute should work on the service contract definition. I haven’t tried that yet.   All the code provided in this blog and in the following files are for sample use. Improvements I don’t like to instantiate a client and a service to test my behaviors. But so far I have' not found an easy way to do it. Today I am passing a type of endpoint to the host creator and it creates the right binding type. This allows me to easily switch between bindings at will. I have used the same approach to test Mex Endpoints, another post should come later for this. Enjoy !
