• WCF Routing Service Filter Generator

  - by Michael Stephenson

  Recently I've been working with the WCF routing service and in our case we were simply routing based on the SOAP Action. This is a pretty good approach for a standard redirection of the message when all messages matching a SOAP Action will go to the same endpoint. Using the SOAP Action also lets you be specific about which methods you expose via the router. One of the things which was a pain was the number of routing rules I needed to create because we were routing for a lot of different methods. I could have explored the option of using a regular expression to match the message to its routing but I wanted to be very specific about what's routed and not risk exposing methods I shouldn't via the router. I decided to put together a little spreadsheet so that I can generate part of the configuration I would need to put in the configuration file rather than have to type this by hand. To show how this works download the spreadsheet from the following url: https://s3.amazonaws.com/CSCBlogSamples/WCF+Routing+Generator.xlsx In the spreadsheet you will see that the squares in green are the ones which you need to amend. In the below picture you can see that you specify a prefix and suffix for the filter name. The core namespace from the web service your generating routing rules for and the WCF endpoint name which you want to route to. In column A you will see the green cells where you add the list of method names which you want to include routing rules for. The spreadsheet will workout what the full SOAP Action would be then the name you will use for that filter in your WCF Routing filters. In column D the spreadsheet will have generated the XML snippet which you can add to the routing filters section in your configuration file. In column E the spreadsheet will have created the XML snippet which you can add to the routing table to send messages matching each filter to the appropriate WCF client endpoint to forward the message to the required destination. Hopefully you can see that with this spreadsheet it would be very easy to produce accurate XML for the WCF Routing configuration if you had a large number of routing rules. If you had additional methods in other services you can simply copy the worksheet and add multiple copies to the Excel workbook. One worksheet per service would work well.

• What ever happened to the Defense Software Reuse System (DSRS)?

  - by emddudley

  I've been reading some papers from the early 90s about a US Department of Defense software reuse initiative called the Defense Software Reuse System (DSRS). The most recent mention of it I could find was in a paper from 2000 - A Survey of Software Reuse Repositories Defense Software Repository System (DSRS) The DSRS is an automated repository for storing and retrieving Reusable Software Assets (RSAs) [14]. The DSRS software now manages inventories of reusable assets at seven software reuse support centers (SRSCs). The DSRS serves as a central collection point for quality RSAs, and facilitates software reuse by offering developers the opportunity to match their requirements with existing software products. DSRS accounts are available for Government employees and contractor personnel currently supporting Government projects... ...The DoD software community is trying to change its software engineering model from its current software cycle to a process-driven, domain-specific, architecture-based, repository-assisted way of constructing software [15]. In this changing environment, the DSRS has the highest potential to become the DoD standard reuse repository because it is the only existing deployed, operational repository with multiple interoperable locations across DoD. Seven DSRS locations support nearly 1,000 users and list nearly 9,000 reusable assets. The DISA DSRS alone lists 3,880 reusable assets and has 400 user accounts... The far-term strategy of the DSRS is to support a virtual repository. These interconnected repositories will provide the ability to locate and share reusable components across domains and among the services. An effective and evolving DSRS is a central requirement to the success of the DoD software reuse initiative. Evolving DoD repository requirements demand that DISA continue to have an operational DSRS site to support testing in an actual repository operation and to support DoD users. The classification process for the DSRS is a basic technology for providing customer support [16]. This process is the first step in making reusable assets available for implementing the functional and technical migration strategies. ... [14] DSRS - Defense Technology for Adaptable, Reliable Systems URL: http://ssed1.ims.disa.mil/srp/dsrspage.html [15] STARS - Software Technology for Adaptable, Reliable Systems URL: http://www.stars.ballston.paramax.com/index.html [16] D. E. Perry and S. S. Popovitch, “Inquire: Predicate-based use and reuse,'' in Proceedings of the 8th Knowledge-Based Software Engineering Conference, pp. 144-151, September 1993. ... Is DSRS dead, and were there any post-mortem reports on it? Are there other more-recent US government initiatives or reports on software reuse?

• Simulate 'Shock absorbtion' with tire rubber in PhysX (2.8.x)

  - by Mungoid

  This is a kinda tricky question and I fear there is no easy enough solution, but I figured I'd hit SE up before giving up on it and just doing what I can. A machine I am working on has no suspension or shocks or springs of any sort in the real machine, so you would think that when it drives over bumps, it would shake like crazy but because its tires (6 of them) are quite large they seem to absorb a lot of shock from the bumps. Part of this is because the machine is around 30k lbs and it just smashes/compresses any bumps in the ground down (This is another issue im still working on) and the other part is that the tires seem to have a lot of flex to them with a lot of air as well. So my current task is to simulate shock absorption in physx without visibly separating the tires from the spindle/axle.. I have been messing with all kinds of NxMaterial, NxSpring, Joints, etc. and have had no luck getting this to work. The main problem is that the spindle attached to the tire is directly in the center and the axle is basically solidly attached to the chassis, so if i give it any spring or suspension travel, that spindle on the tires will move upwards or downwards, looking very odd because now its not any longer in the center of the tire. I tried giving it a higher restitution but that just makes it bouncy without any shock absorption. Another avenue I am messing with is to actively smooth the terrain in front of the tires so that before it hits a bumpy patch, that patch is smoothed and it doesn't bounce. The only issue with this is that it is pretty expensive to do with 6 tires, high tesselation of the terrain and other complex things going on at the same time in this simulation. I am still working on this but I am hoping to mix and match a few different aspects to get the best possible outcome. This is a bit of a complex issue so I'm not expecting anyone to have a definitive answer, just hoping someone may think of something I haven't =-) -Side note: Yes i know PhysX 2.8.x is quite outdated but we have to stick with it for this implementation. We are in the process of going to another physics engine but it is out of scope to apply that engine to this project.

• F# and the useful infinite Sequence (I think)

  - by MarkPearl

  So I have seen a few posts done by other F# fans on solving project Euler problems. They looked really interesting and I thought with my limited knowledge of F# I would attempt a few and the first one I had a look at was problem 5. Which said : “2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder. What is the smallest number that is evenly divisible by all of the numbers from 1 to 20?” So I jumped into coding it and straight away got stuck – the C# programmer in me wants to do a loop, starting at one and dividing every number by 1 to 20 to see if they all divide and once a match is found, there is your solution. Obviously not the most elegant way but a good old brute force approach. However I am pretty sure this would not be the F# way…. So after a bit of research I found the Sequences and how useful they were. Sequences seemed like the beginning of an approach to solve my problem. In my head I thought - create a sequence, and then start at the beginning of it and move through it till you find a value that is divisible by 1 to 20. Sounds reasonable? So the question is begged - how would you create a sequence that you are sure will be large enough to hold the solution to the problem? Well… You can’t know! Some more googling and I found what I would call infinite sequences – something that looks like this… let nums = 1 |> Seq.unfold (fun i -> Some (i, i + 1))   My interpretation of this would be as follows… create a sequence, and whenever it is called add 1 to its size (I would appreciate someone helping me on wording this right functionally). Something that I don’t understand fully yet is the forward pipe operator (|>) which I think plays a key role in this code. With this in hand I was able to code a basic optimized solution to this problem. I’m going to go over it some more before I post the full code just in case!

• ADF Mobile Released!!

  - by Denis T

  ADFmfAnnounce We are pleased to announce the general availability of the newest version of Oracle’s ADF Mobile framework. This new framework provides the much anticipated on-device capabilities that the latest mobile applications require.  Feature Highlights Java - Oracle brings a Java VM embedded with each application so you can develop all your business logic in the platform neutral language you know and love! (Yes, even iOS!) JDBC - Since we give you Java, we also provide JDBC along with a SQLite driver and engine that also supports encryption out of the box. Multi-Platform - Truly develop your application only once and deploy to multiple platforms. iOS and Android platforms are supported for both phone and tablet. Flexible - You can decide how to implement the UI: (a) Use existing server-based UI framework like JSF. (b) Use your own favorite HTML5 framework like JQuery. (c) Use our declarative HTML5 component set provided with the framework. ADF Mobile XML or AMX for short, provides all the normal input and layout controls you expect and we also add charts/maps/gauges along with it to provide a very comprehensive UI controls. You can also mix and match any of the three for ultimate flexibility! Device Feature Access - You can get access to device features from either Java or JavaScript to invoke features like camera, GPS, email, SMS, contacts, etc. Secure - ADF Mobile provides integrated security that works with your server back-end as well. Whether you’re using remote URLs, local HTML or AMX, you can secure any/all of your features with a single consistent login page. Since we also give you SQLite encryption, we are assured that your data is safe. Rapid - Using the same development techniques that ADF developers are already used to, you can quickly create mobile applications without ever learning another language! Architecture ADF Mobile is a “hybrid” architecture that employs a natively built “container” on each platform that hosts a number of browser windows that are used to display the application content. We add the Java VM as a natively built library to the container for business logic.   How To Get Started ADF Mobile is an extension to the recently released JDeveloper version 11.1.2.3.0. Simple get the latest JDeveloper from Oracle Technology Network and use the Check for Updates feature to get the ADF Mobile extension. Note: ADF Mobile does not require developers to learn any other languages or frameworks but to build/deploy to iOS, you must be on an Apple MacintoshTM and have Xcode installed. To build/deploy to Android™ you must have the Android SDK installed.

• git workflow for separating commits

  - by gman

  Best practices with git (or any VCS for that matter) is supposed to be to have each commit do the smallest change possible. But, that doesn't match how I work at all. For example I recently I needed to add some code that checked if the version of a plugin to my system matched the versions the system supports. If not print a warning that the plugin probably requires a newer version of the system. While writing that code I decided I wanted the warnings to be colorized. I already had code that colorized error message so I edited that code. That code was in the startup module of one entry to the system. The plugin checking code was in another path that didn't use that entry point so I moved the colorization code into a separate module so both entry points could use it. On top of that, in order to test my plugin checking code works I need to go edit UI/UX code to make sure it tells the user "You need to upgrade". When all is said and done I've edited 10 files, changed dependencies, the 2 entry points are now both dependant on the colorization code, etc etc. Being lazy I'd probably just git add . && git commit -a the whole thing. Spending 10-15 minutes trying to manipulate all those changes into 3 to 6 smaller commits seems frustrating which brings up the question Are there workflows that work for you or that make this process easier? I don't think I can some how magically always modify stuff in the perfect order since I don't know that order until after I start modifying and seeing what comes up. I know I can git add --interactive etc but it seems, at least for me, kind of hard to know what I'm grabbing exactly the correct changes so that each commit is actually going to work. Also, since the changes are sitting in the current directory it doesn't seem like it would be easy to run tests on each commit to make sure it's going to work short of stashing all the changes. And then, if it were to stash and then run the tests, if I missed a few lines or accidentally added a few too many lines I have no idea how I'd easily recover from that. (as in either grab the missing lines from the stash and then put the rest back or take the few extra lines I shouldn't have grabbed and shove them into the stash for the next commit. Thoughts? Suggestions? PS: I hope this is an appropriate question. The help says development methodologies and processes

• [EF + Oracle] Inserting Data (Sequences) (2/2)

  - by JTorrecilla

  Prologue In the previous chapter we have see how to create DB records with EF, now we are going to Some Questions about Oracle.   ORACLE One characteristic from SQL Server that differs from Oracle is “Identity”. To all that has not worked with SQL Server, this property, that applies to Integer Columns, lets indicate that there is auto increment columns, by that way it will be filled automatically, without writing it on the insert statement. In EF with SQL Server, the properties whose match with Identity columns, will be filled after invoking SaveChanges method. In Oracle DB, there is no Identity Property, but there is something similar. Sequences Sequences are DB objects, that allow to create auto increment, but there are not related directly to a Table. The syntax is as follows: name, min value, max value and begin value. 1: CREATE SEQUENCE nombre_secuencia 2: INCREMENT BY numero_incremento 3: START WITH numero_por_el_que_empezara 4: MAXVALUE valor_maximo | NOMAXVALUE 5: MINVALUE valor_minimo | NOMINVALUE 6: CYCLE | NOCYCLE 7: ORDER | NOORDER 8:    How to get sequence value? To obtain the next val from the sequence: 1: SELECT nb_secuencia.Nextval 2: From Dual Due to there is no direct way to indicate that a column is related to a sequence, there is several ways to imitate the behavior: Use a Trigger (DB), Use Stored Procedures or Functions(…) or my particularly option. EF model, only, imports Table Objects, Stored Procedures or Functions, but not sequences. By that, I decide to create my own extension Method to invoke Next Val from a sequence: 1: public static class EFSequence 2: { 3: public static int GetNextValue(this ObjectContext contexto, string SequenceName) 4: { 5: string Connection = ConfigurationManager.ConnectionStrings["JTorrecillaEntities2"].ConnectionString; 6: Connection=Connection.Substring(Connection.IndexOf(@"connection string=")+19); 7: Connection = Connection.Remove(Connection.Length - 1, 1); 8: using (IDbConnection con = new Oracle.DataAccess.Client.OracleConnection(Connection)) 9: { 10: using (IDbCommand cmd = con.CreateCommand()) 11: { 12: con.Open(); 13: cmd.CommandText = String.Format("Select {0}.nextval from DUAL", SequenceName); 14: return Convert.ToInt32(cmd.ExecuteScalar()); 15: } 16: } 17:  18: } 19: } This Object Context’s extension method are going to invoke a query with the Sequence indicated by parameter. It takes the connection strings from the App settings, removing the meta data, that was created by VS when generated the EF model. And then, returns the next value from the Sequence. The next value of a Sequence is unique, by that, when some concurrent users are going to create records in the DB using the sequence will not get duplicates. This is my own implementation, I know that it could be several ways to do and better ways. If I find any other way, I promise to post it. To use the example is needed to add a reference to the Oracle (ODP.NET) dll.

• URL slugs: ideal length, and the real SEO effects of these slugs

  - by tattvamasi

  this question is addressed widely on SO and outside it, but for some reason, instead of taking it as a good load of great advice, all this information is confusing me. ** Problem ** I already had, on one of my sites, "prettified" urls. I had taken out the query strings, rewritten the URLS, and the link was short enough for me, but had a problem: the ID of the item or post in the URL isn't good for users. One of the users asked is there's a way to get rid of numbers, and I thought it was better for users to just see a clue of the page content in the URL. ** Solution ** With this in mind, I am trying with a section of the site.Armed with 301 redirects, some parsing work, and a lot of patience, I have added the URL slugs to some blog entries, and the slug of the URL reports the title of the article (something close to http://example.com/my-news/terribly-boring-and-long-url-that-replaces-the-number-I-liked-so-much/ ** Problems after Solution ** The problem, as I see it, is that now the URL of those blog articles is very descriptive for sure, but it is also impossible to remember. So, this brings me to the same issue I had with my previous problem: if numbers say nothing and can't be remembered, what's the use of these slugs? I prefer to see http://example.com/my-news/1/ than http://example.com/my-news/terribly-boring-and-long-url-that-replaces-the-number-I-liked-so-much/ To avoid forcing my user to memorize my URLS, I have added a script that finds the closest match to the URL you type, and redirects there. This is something I like, because the page now acts as a sort of little search engine, and users can play with the URLS to find articles. ** Open questions ** I still have some open questions, and don't seem to be able to find an answer, because answers tend to contradict one another. 1) How many characters should an URL ideally be long? I've read the magic number 115 and am sticking to that, but am not sure. 2) Is this really good for SEO? One of those blog articles I have redirected, with ID number in the URL and all, ranked second on Google. I've just found this question, and the answer seems to be consistent with what I think URL slug and SEO - structure (but see this other question with the opposite opinion) 3) To make a question with a specific example, would this URL risk to be penalized? Is it acceptable? Is it too long? StackOverflow seems to have comparably long URLs, but I'm not sure it's a winning strategy in my case. I just wanted to facilitate my users without running into Google's algorithms.

• SSTP client disconnects shortly after successfully connected to VPN

  - by Eran Betzalel

  I'm successfully authenticating and connecting to a SSTP VPN (on windows 2008) from my windows 7 machine, but for some reason, the connection is disconnected about a 1-2 seconds after it's established. I've done the following: Defined a SSTP VPN on my windows server 2008. Defined the same machine as CA. Issued the needed certificates and published them on the client. I'm currently testing this VPN inside my LAN so all the needed ports are opened. Here are the event log entries when trying to connect: Error Log (Client): The user HOME\User dialed a connection named Home VPN which has terminated. The reason code returned on termination is 829. Error Log (Server-VPN): The user HOME\User connected on port VPN0-0 on 7/27/2012 at 1:57 AM and disconnected on 7/27/2012 at 1:57 AM. The user was active for 0 minutes 0 seconds. 312 bytes were sent and 4528 bytes were received. The reason for disconnecting was user request. What would be the issue? How can I resolve or debug it? UPDATE: I've found an event log (Log=System, Source=RasSstp) message on the windows 7 machine that tries to connect to the VPN: The SSTP-based VPN connection to the remote access server was terminated because of a security check failure. Security settings on the remote access server do not match settings on this computer. Contact the system administrator of the remote access server and relay the following information: SHA1 Certificate Hash: 065D681...520375552F SHA256 Certificate Hash: 18DED363...EEEE28CFD00

• Reinstall Acer OEM Windows 8, Windows 8 Recovery for Acer Aspire V5 122p

  - by stwindr

  My Acer Aspire V5-122P-61456G50NSS, model - MS2377, has crashed all together. It came preloaded with Windows 8 and I upgraded to windows 8.1 3-4 days before crash. Unfortunately I did not make any recovery media before the crash. While accessing the eRecovery on Acer store with my PC's serial no. it says nor RCD available for this. I tried recovery by loading recovery manager (Left Alt + F10) Various other advanced startup options (like holding shift key while turning on or pressing F8 key) returns nothing but no luck. However I am able to enter BIOS. After doing research on above condition on various PC forums, now my questions: I read that a 'Windows Recovery Drive' can be made on any PC running Windows 8 and could be used to repair another PC. Does anybody in SuperUser community have that (or a link to download the same from somewhere? as I'm unable to find anybody running windows 8 among my friends). I downloaded a window 8 Pro ISO and made a bootable USB. I was able to go to 'Repair Your Computer' option and after going to 'Reset your PC' option found that my recovery partition has gone/missing. I tried all options available but no luck. Then I tried to install with that Windows 8 Pro ISO but got message: "The product key entered does not match any of the Windows images available for installation. Enter a different product key". before this message I did not got any form to fill product key! Does this mean that the installer was picking up the key from BIOS (OEM Key)? and may be the installation did not succeeded because OEM Windows version was Window 8 and I was trying to install Windows 8 Pro. If that is the case then, could somebody please send me link to download an Windows 8 ISO? I am helpless and couldn't find anywhere on internet (without having to pay for a new key, but I should not pay as the installer will use OEM key).

• QNTC and Windows Server 2008 R2

  - by Ben

  I am having a really hard time getting an iSeries (AS/400) machine talking to my new Windows Server 2008 R2 box using the QNTC file system on the iSeries. I had similar problems getting it to initially talk to a Windows Server 2003 machine, but enabling the local Guest account on the 2003 box solved that one. No such luck with the new 2008 box. When I do a WRKLNK /QNTC/SVR01 on the iSeries (which should show share listings, and does on any 2003 boxes) all I get is (Cannot find object to match specified name.). I know the iSeries likes the same username and password on the remote server, but unfortunately for us this is not the case. Anyhow, it does currently work with different username/password combinations on a 2003 box. To try and get the wretched things talking, I have made the 2008 server pretty open but the iSeries will not see shares on it. I have enabled the local Guest account, turned Windows firewall off, set the share permissions so Everyone has full control but to no avail. I read something on the internet about the iSeries only being able to handle NTLM authentication (and I understand by default that Server 2008 R2 only uses NTLMv2 and has NTLM disabled), so I made a special group policy for the server and tweaked all Group Policy settings under Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\Security Options but the iSeries STILL won't see it. We have a team of programmers who do all the system administration of the iSeries, but they are stumped for ideas on their side, and I'm stumped for ideas on my side. This is driving me crazy now, and if anybody has managed to get an iSeries to talk to Windows Server 2008 R2 using QNTC I would be very appreciative of any suggestions, be it on the Windows side, iSeries settings or even IBM PTF's that might patch anything. The iSeries is running V5R4 and I have *SECOFR privileges on it, if it helps. One final (most important!) note - The programmers think it's my system being tricky, and I think it's theirs - please prove me right :)

• Telling subversion client to ignore certificate errors

  - by Pekka

  I have set up a copy of Redmine through the Bitnami Redmine Stack and am having trouble accessing a remote SVN repository through https. The trouble seems to be related to the fact that I don't have a signed certificate, and the certificate provided doesn't match the host name (I am accessing the same server through a number of host names). I am new to Ruby, Mongrel, Rails and Redmine. Following the advice in this forum thread, I changed the path Redmine uses to invoke the svn client in \apps\redmine\lib\ redmine\scm\adapters\subversion_adapter.rb from SVN_BIN = "svn" to SVN_BIN = "svn --trust-server-cert --non-interactive --config-dir c:/user/temp" I was hoping that the --trust-server-cert option would fix the certificate problem. However, I am still getting the following error message in mongrel.log: svn: OPTIONS of 'https://server.xyz:8443/svn/reponame': Server certificate verification failed: certificate issued for a different hostname, issuer is not trusted (https://server.xyz:8443) Does anybody know what to do about this? Additional info: I re-started the mongrel service after each change I am sure the configuration change has taken effect because subversion has created a full configuration directory in c:\user\temp I can access the remote repository using command line svn no problem The remote repository runs on a Windows box with VisualSVN

• Juniper EX3300 routing issue

  - by Richard Whitman

  The routing on my Juniper EX3300 does not seem to be working. My ISP's gateway is at xx.xx.xx.xx. And I have the following in the configuration: routing-options { static { route 0.0.0.0/0 { next-hop xx.xx.xx.xx; retain; } } } I can ping to my ISP's gateway from the switch. However, I can NOT ping to any other IP. When I do a traceroute (to Google.com's IP). This is what I get: traceroute to 74.125.224.69 (74.125.224.69), 30 hops max, 40 byte packets traceroute: sendto: No route to host 1 traceroute: wrote 74.125.224.69 40 chars, ret=-1 *traceroute: sendto: No route to host Do I need to enable any protocols? I guess this goes without saying, but I am kind of new to Junos.

• My SMTP's outgoing mail gets bounced

  - by BloodPhilia

  I've got a ISPconfig 3 production server set up, running Ubuntu Server 9.04. My e-mail gets delivered ok to almost every other server I send mail to except for one (smtp.chello.nl which bounces my email). In my /var/log/mail.err I found the below error.

• How to avoid lftp Certificate verification error?

  - by pattulus

  I'm trying to get my Pelican blog working. It uses lftp to transfer the actual blog to ones server, but I always get an error: mirror: Fatal error: Certificate verification: subjectAltName does not match ‘blogname.com’ I think lftp is checking the SSL and the quick setup of Pelican just forgot to include that I don't have SSL on my FTP. This is the code in Pelican's Makefile: ftp_upload: $(OUTPUTDIR)/index.html lftp ftp://$(FTP_USER)@$(FTP_HOST) -e "mirror -R $(OUTPUTDIR) $(FTP_TARGET_DIR) ; quit" which renders in terminal as: lftp ftp://[email protected] -e "mirror -R /Volumes/HD/Users/me/Test/output /myblog_directory ; quit" What I managed so far is, denying the SSL check by changing the Makefile to: lftp ftp://$(FTP_USER)@$(FTP_HOST) -e "set ftp:ssl-allow no" "mirror -R $(OUTPUTDIR) $(FTP_TARGET_DIR) ; quit" Due to my incorrect implementation I get logged in correctly (lftp [email protected]:~>) but the one line feature doesn't work anymore and I have to enter the mirror command by hand: mirror -R /Volumes/HD/Users/me/Test/output/ /myblog_directory This works without an error and timeout. The question is how to do this with a one liner. In addition I tried: set ssl:verify-certificate/ftp.myblog.com no This trick to disable certificate verification in lftp: $ cat ~/.lftp/rc set ssl:verify-certificate no However, it seems there is no "rc" folder in my lftp directory - so this prompt has no chance to work.

• Cisco PIX to Juniper Netscreen Policy-based VPN fails Phase 2 Proposal

  - by elint

  I've followed the instructions to configure a VPN between a netscreen device and a Cisco PIX as directed by Cisco's [netscreen to PIX VPN]http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a00801c4445.shtml article. The only differences are that I'm running PIX 6.3(5) and Juniper Netscreen 6.1.0r2.0 (Firewall+VPN). I followed both configurations exactly, and when I try to connect, the Juniper returns with: 2010-02-21 12:54:28 information IKE: Removed Phase 2 SAs after receiving a notification message. 2010-02-21 12:54:28 information IKE pix_public_IP: Received a notification message for DOI 1 14 NO-PROPOSAL-CHOSEN. 2010-02-21 12:54:28 information IKE pix_public_IP Phase 2: Initiated negotiations. On the Netscreen, I've created a Phase 2 Proposal called ToCorpOffice using DH Group#2, 3DES-CBC, and SHA-1, and when configuring the AutoKey IKE, I chose ToCorpOffice and removed all other transforms. I believe I've configured the same on the PIX with: sysopt connection permit-ipsec crypto ipsec transform-set mytrans esp-3des esp-sha-hmac crypto map mymap 10 ipsec-isakmp crypto map mymap 10 match address nonat crypto map mymap 10 set pfs group2 crypto map mymap 10 set peer netscreen_public_ip crypto map mymap 10 set transform-set mytrans crypto map mymap interface outside Saved that and rebooted, so here's the cryptomap info: PIX-FW1# show crypto map Crypto Map: "mymap" interfaces: { outside } Crypto Map "mymap" 10 ipsec-isakmp Peer = netscreen_public_ip access-list nonat; 1 elements access-list nonat line 1 permit ip 192.168.1.0 255.255.255.0 192.168.2.0 255.255.255.0 (hitcnt=0) Current peer: netscreen_public_ip Security association lifetime: 4608000 kilobytes/28800 seconds PFS (Y/N): Y DH group: group2 Transform sets={ mytrans, } PIX-FW1# Any idea why I'm getting a NO-PROPOSAL-CHOSEN error?

• IIS 7 returns 304 instead of 200

  I have a strange issue with IIS 7. Sometimes it seems to return a 304 instead of a 200.

• Firebird 2.1: gfix -online returns "database shutdown"

  - by darvids0n

  Hey all. Googling this one hasn't made a bit of difference, unfortunately, as most results specify the syntax for onlining a database after using gfix -shut -force 30 (or any other number of seconds) as gfix -online dbname, and I have run gfix -online dbname with and without login credentials for the DB in question. The message that I get is: database dbname shutdown Which is fine, except that I want to bring it online now. It's out of the question to close fbserver.exe (running on a Windows box, afaik it's Classic Server 2.1.1 but it may be Super) since we have other databases running off of that which need almost 24/7 uptime. The message from doing another gfix -shut -force or -attach or -tran is invalid shutdown mode for dbname which appears to match with the documentation of what happens if the database is already fully shut down. Ideas and input greatly appreciated, especially since at the moment time is a factor for me. Thanks! EDIT: The whole reason I shut down the DB is to clear out "active" transactions which were linked to a specific IP address, and that computer is my dev terminal (actually a virtual machine where I develop frontends for the database software) but I had no processes connecting to the database at the time. They looked like orphaned transactions to me, and they weren't in limbo afaik. Running a manual sweep didn't clear them out, deleting the rows from MON$STATEMENTS didn't work even though Firebird 2.1 supposedly supports cancelling queries that way. My last resort was to "restart" the database, hence the above issue.

• Dynamic DNS updates for Linux and Mac OS X machines with a Windows DNS server

  - by DanielGibbs

  My network has a Windows machine running Server 2008 R2 which provides DHCP and DNS. I'm not particularly familiar with Windows domains, but the domain is set to home.local and that is the DNS domain name provided with DHCP leases. Everything works fine for Windows machines, they get the lease and update the server with their hostname and the server creates a DNS records for windowshostname.home.local. I am having problems obtaining the same functionality on Linux (Debian) and Mac OS X (Mountain Lion) machines. They receive DHCP just fine, but DNS entries are not being created on the server for them. On the Mac OS X machine, hostname gives an output of machostname.local, and on the Linux machine hostname --fqdn also gives an output of linuxhostname.local. I'm assuming that the server is not creating DNS entries because the domain does not match that of the server (home.local). I don't want to statically configure these machines to be part of the home.local domain, I just want them to pick it up from DHCP and be able to have entries in the DNS server. How should I go about doing this?
