  • No Customer Left Behind

    - by Kathryn Perry
    A guest post by David Vap, Group Vice President, Oracle Applications Product Development What does customer experience mean to you? Is it a strategy for your executives? A new buzz word and marketing term? A bunch of CRM technology with social software added on? For me, customer experience is a customer-centric worldview that produces a deeper understanding of your business and what it takes to achieve sustainable, differentiated success. It requires you to prioritize and examine the journey your customers are on with your brand, so you can answer the question, "How can we drive greater value for our business by delivering a better customer experience?" Businesses that embrace a customer-centric worldview understand their business at a much deeper level than most. They know who their customers are, what their value is, what they do, what they say, what they want, and ultimately what that means to their business. "Why Isn't Everyone Doing It?" We're all consumers who have our own experiences with many brands. Good or bad, some of those experiences stay with us. So viscerally we understand the concept of customer experience from the stories we share. One that stands out in my mind happened as I was preparing to leave for a 12-month job assignment in Europe. I wanted to put my cable television subscription on hold. I wasn't leaving for another vendor. I wasn't upset. I just had a situation where it made sense to put my $180 per month account on pause until I returned. Unfortunately, there was no way for this cable company to acknowledge that I was a loyal customer with a logical request - and to respond accordingly. So, ultimately, they lost my business. Research shows us that it costs six to seven times more to acquire a new customer than to retain an existing one. Heavily funding the efforts of getting new customers and underfunding the efforts of serving the needs of your existing (who are your greatest advocates) is a vicious and costly cycle. "Hey, These Guys Suck!" I love my Apple iPad because it's so easy to use. The explosion of these types of technologies, combined with new media channels, has raised our expectations and made us hyperaware of what's going on and what's available. In addition, social media has given us a megaphone to share experiences both positive and negative with greater impact. We are now an always-on culture that thrives on our ability to access, connect, and share anywhere anytime. If we don't get the service, product, or value we expect, it is easy to tell many people about it. We also can quickly learn where else to get what we want. Consumers have the power of influence and choice at a global scale. The businesses that understand this principle are able to leverage that power to their advantage. The ones that don't, suffer from it. Which camp are you in?Note: This is Part 1 in a three-part series. Stop back for Part 2 on November 19.

  • The long road to bug-free software

    - by Tony Davis
    The past decade has seen a burgeoning interest in functional programming languages such as Haskell or, in the Microsoft world, F#. Though still on the periphery of mainstream programming, functional programming concepts are gradually seeping into the imperative C# language (for example, Lambda expressions have their root in functional programming). One of the more interesting concepts from functional programming languages is the use of formal methods, the lofty ideal behind which is bug-free software. The idea is that we write a specification that describes exactly how our function (say) should behave. We then prove that our function conforms to it, and in doing so have proved beyond any doubt that it is free from bugs. All programmers already use one form of specification, specifically their programming language's type system. If a value has a specific type then, in a type-safe language, the compiler guarantees that value cannot be an instance of a different type. Many extensions to existing type systems, such as generics in Java and .NET, extend the range of programs that can be type-checked. Unfortunately, type systems can only prevent some bugs. To take a classic problem of retrieving an index value from an array, since the type system doesn't specify the length of the array, the compiler has no way of knowing that a request for the "value of index 4" from an array of only two elements is "unsafe". We restore safety via exception handling, but the ideal type system will prevent us from doing anything that is unsafe in the first place and this is where we start to borrow ideas from a language such as Haskell, with its concept of "dependent types". If the type of an array includes its length, we can ensure that any index accesses into the array are valid. The problem is that we now need to carry around the length of arrays and the values of indices throughout our code so that it can be type-checked. In general, writing the specification to prove a positive property, even for a problem very amenable to specification, such as a simple sorting algorithm, turns out to be very hard and the specification will be different for every program. Extend this to writing a specification for, say, Microsoft Word and we can see that the specification would end up being no simpler, and therefore no less buggy, than the implementation. Fortunately, it is easier to write a specification that proves that a program doesn't have certain, specific and undesirable properties, such as infinite loops or accesses to the wrong bit of memory. If we can write the specifications to prove that a program is immune to such problems, we could reuse them in many places. The problem is the lack of specification "provers" that can do this without a lot of manual intervention (i.e. hints from the programmer). All this might feel a very long way off, but computing power and our understanding of the theory of "provers" advances quickly, and Microsoft is doing some of it already. Via their Terminator research project they have started to prove that their device drivers will always terminate, and in so doing have suddenly eliminated a vast range of possible bugs. This is a huge step forward from saying, "we've tested it lots and it seems fine". What do you think? What might be good targets for specification and verification? SQL could be one: the cost of a bug in SQL Server is quite high given how many important systems rely on it, so there's a good incentive to eliminate bugs, even at high initial cost. [Many thanks to Mike Williamson for guidance and useful conversations during the writing of this piece] Cheers, Tony.

He adds that process manufacturing organizations such as oil and gas, utilities, and chemicals must manage this level of investment in an environment of constrained capital markets, erratic supply and demand, aging infrastructure, heightened regulations, and declining global skills. In the following interview, Graham explains how the right enterprise project portfolio management (EPPM) technology can help the industry meet these imperatives. Q: Why is EPPM so important for today’s process manufacturers? A: If the industry invests US$38 trillion without proper cost controls in place, a huge amount of resources will be put at risk, especially when it comes to cost overruns that may occur in large capital projects. Process manufacturing companies must not only control costs, but also monitor all the various contractors that will be involved in each project. If you’re not managing your own workers and all the interdependencies among the different contractors, then you’ve got problems. Q: What else should process manufacturers look for? A: It’s also important that an EPPM solution has the ability to manage more than just capital projects. For example, it’s best to manage maintenance and capital projects in the same system. Say you’re due to install a new transformer in a power station as part of a capital project, but routine maintenance in that area of the facility is scheduled for that morning. The lack of coordination could lead to unforeseen delays. There are also IT considerations that impact capital projects, such as adding servers and network cable for a control system in a power station. What organizations need is a true EPPM system that’s not just for capital projects, maintenance, or IT activities, but instead an enterprisewide solution that provides visibility into all types of projects. Read the complete Q&A here and discover the practical framework for successfully managing this massive capital spending.

  • Writing a method to 'transform' an immutable object: how should I approach this?

    - by Prog
    (While this question has to do with a concrete coding dilemma, it's mostly about what's the best way to design a function.) I'm writing a method that should take two Color objects, and gradually transform the first Color into the second one, creating an animation. The method will be in a utility class. My problem is that Color is an immutable object. That means that I can't do color.setRGB or color.setBlue inside a loop in the method. What I can do, is instantiate a new Color and return it from the method. But then I won't be able to gradually change the color. So I thought of three possible solutions: 1- The client code includes the method call inside a loop. For example: int duration = 1500; // duration of the animation in milliseconds int steps = 20; // how many 'cycles' the animation will take for(int i=0; i<steps; i++) color = transformColor(color, targetColor, duration, steps); And the method would look like this: Color transformColor(Color original, Color target, int duration, int steps){ int redDiff = target.getRed() - original.getRed(); int redAddition = redDiff / steps; int newRed = original.getRed() + redAddition; // same for green and blue .. Thread.sleep(duration / STEPS); // exception handling omitted return new Color(newRed, newGreen, newBlue); } The disadvantage of this approach is that the client code has to "do part of the method's job" and include a for loop. The method doesn't do it's work entirely on it's own, which I don't like. 2- Make a mutable Color subclass with methods such as setRed, and pass objects of this class into transformColor. Then it could look something like this: void transformColor(MutableColor original, Color target, int duration){ final int STEPS = 20; int redDiff = target.getRed() - original.getRed(); int redAddition = redDiff / steps; int newRed = original.getRed() + redAddition; // same for green and blue .. for(int i=0; i<STEPS; i++){ original.setRed(original.getRed() + redAddition); // same for green and blue .. Thread.sleep(duration / STEPS); // exception handling omitted } } Then the calling code would usually look something like this: // The method will usually transform colors of JComponents JComponent someComponent = ... ; // setting the Color in JComponent to be a MutableColor Color mutableColor = new MutableColor(someComponent.getForeground()); someComponent.setForeground(mutableColor); // later, transforming the Color in the JComponent transformColor((MutableColor)someComponent.getForeground(), new Color(200,100,150), 2000); The disadvantage is - the need to create a new class MutableColor, and also the need to do casting. 3- Pass into the method the actual mutable object that holds the color. Then the method could do object.setColor or similar every iteration of the loop. Two disadvantages: A- Not so elegant. Passing in the object that holds the color just to transform the color feels unnatural. B- While most of the time this method will be used to transform colors inside JComponent objects, other kinds of objects may have colors too. So the method would need to be overloaded to receive other types, or receive Objects and have instanceof checks inside.. Not optimal. Right now I think I like solution #2 the most, than solution #1 and solution #3 the least. However I'd like to hear your opinions and suggestions regarding this.

  • Asterisk SIP digest authentication username mismatch

    - by Matt
    I have an asterisk system that I'm attempting to get to work as a backup for our 3com system. We already use it for a conference bridge. Our phones are the 3com 3C10402B, so I don't have the issue of older 3com phones that come without a SIP image. The 3com phones are communicating SIP with the Asterisk, but are unable to register because they present a digest username value that doesn't match what Asterisk thinks it should. As an example, here are the relevant lines from a successful registration from a soft phone: Server sends: WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="1cac3853" Phone responds: Authorization: Digest username="2321", realm="asterisk", nonce="1cac3853", uri="sip:192.168.254.12", algorithm=md5, response="d32df9ec719817282460e7c2625b6120" For the 3com phone, those same lines look like this (and fails): Server sends: WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="6c915c33" Phone responds: Authorization: Digest username="sip:[email protected]", realm="asterisk", nonce="6c915c33", uri="sip:192.168.254.12", opaque="", algorithm=MD5, response="a89df25f19e4b4598595f919dac9db81" Basically, Asterisk wants to see a username in the Digest username field of 2321, but the 3com phone is sending sip:[email protected]. Anyone know how to tell asterisk to accept this format of username in the digest authentication? Here is the sip.conf info for that extension: [2321] deny=0.0.0.0/0.0.0.0 disallow=all type=friend secret=1234 qualify=yes port=5060 permit=0.0.0.0/0.0.0.0 nat=yes mailbox=2321@device host=dynamic dtmfmode=rfc2833 dial=SIP/2321 context=from-internal canreinvite=no callerid=device <2321 allow=ulaw, alaw call-limit=50 ... and for those interested in the grit, here is the debug output of the registration attempt: REGISTER sip:192.168.254.12 SIP/2.0 v: SIP/2.0/UDP 192.168.254.157:5060 t: f: i: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18580 REGISTER Max-Forwards: 70 m: ;dt=544 Expires: 3600 User-Agent: 3Com-SIP-Phone/V8.0.1.3 X-3Com-PhoneInfo: firstRegistration=no; primaryCallP=192.168.254.12; secondaryCallP=0.0.0.0; --- (11 headers 0 lines) --- Using latest REGISTER request as basis request Sending to 192.168.254.157 : 5060 (no NAT) SIP/2.0 100 Trying Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18580 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Contact: Content-Length: 0 SIP/2.0 401 Unauthorized Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: ;tag=as3fb867e2 Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18580 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="6c915c33" Content-Length: 0 Scheduling destruction of SIP dialog 'fa4451d8-01d6-1cc2-13e4-00e0bb33beb9' in 32000 ms (Method: REGISTER) confbridge*CLI REGISTER sip:192.168.254.12 SIP/2.0 v: SIP/2.0/UDP 192.168.254.157:5060 t: f: i: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18581 REGISTER Max-Forwards: 70 m: ;dt=544 Expires: 3600 User-Agent: 3Com-SIP-Phone/V8.0.1.3 Authorization: Digest username="sip:[email protected]", realm="asterisk", nonce="6c915c33", uri="sip:192.168.254.12", opaque="", algorithm=MD5, response="a89df25f19e4b4598595f919dac9db81" X-3Com-PhoneInfo: firstRegistration=no; primaryCallP=192.168.254.12; secondaryCallP=0.0.0.0; --- (12 headers 0 lines) --- Using latest REGISTER request as basis request Sending to 192.168.254.157 : 5060 (NAT) SIP/2.0 100 Trying Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18581 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Contact: Content-Length: 0 SIP/2.0 403 Authentication user name does not match account name Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: ;tag=as3fb867e2 Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18581 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Content-Length: 0 Scheduling destruction of SIP dialog 'fa4451d8-01d6-1cc2-13e4-00e0bb33beb9' in 32000 ms (Method: REGISTER) Thanks for your input!

  • SSL connection errors from Apache

Could someone help me with this issue? Thank you in advance.

  • Asterisk SIP digest authentication username mismatch

    - by Matt
    I have an asterisk system that I'm attempting to get to work as a backup for our 3com system. We already use it for a conference bridge. Our phones are the 3com 3C10402B, so I don't have the issue of older 3com phones that come without a SIP image. The 3com phones are communicating SIP with the Asterisk, but are unable to register because they present a digest username value that doesn't match what Asterisk thinks it should. As an example, here are the relevant lines from a successful registration from a soft phone: Server sends: WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="1cac3853" Phone responds: Authorization: Digest username="2321", realm="asterisk", nonce="1cac3853", uri="sip:192.168.254.12", algorithm=md5, response="d32df9ec719817282460e7c2625b6120" For the 3com phone, those same lines look like this (and fails): Server sends: WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="6c915c33" Phone responds: Authorization: Digest username="sip:[email protected]", realm="asterisk", nonce="6c915c33", uri="sip:192.168.254.12", opaque="", algorithm=MD5, response="a89df25f19e4b4598595f919dac9db81" Basically, Asterisk wants to see a username in the Digest username field of 2321, but the 3com phone is sending sip:[email protected]. Anyone know how to tell asterisk to accept this format of username in the digest authentication? Here is the sip.conf info for that extension: [2321] deny=0.0.0.0/0.0.0.0 disallow=all type=friend secret=1234 qualify=yes port=5060 permit=0.0.0.0/0.0.0.0 nat=yes mailbox=2321@device host=dynamic dtmfmode=rfc2833 dial=SIP/2321 context=from-internal canreinvite=no callerid=device <2321 allow=ulaw, alaw call-limit=50 ... and for those interested in the grit, here is the debug output of the registration attempt: REGISTER sip:192.168.254.12 SIP/2.0 v: SIP/2.0/UDP 192.168.254.157:5060 t: f: i: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18580 REGISTER Max-Forwards: 70 m: ;dt=544 Expires: 3600 User-Agent: 3Com-SIP-Phone/V8.0.1.3 X-3Com-PhoneInfo: firstRegistration=no; primaryCallP=192.168.254.12; secondaryCallP=0.0.0.0; --- (11 headers 0 lines) --- Using latest REGISTER request as basis request Sending to 192.168.254.157 : 5060 (no NAT) SIP/2.0 100 Trying Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18580 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Contact: Content-Length: 0 SIP/2.0 401 Unauthorized Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: ;tag=as3fb867e2 Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18580 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="6c915c33" Content-Length: 0 Scheduling destruction of SIP dialog 'fa4451d8-01d6-1cc2-13e4-00e0bb33beb9' in 32000 ms (Method: REGISTER) confbridge*CLI REGISTER sip:192.168.254.12 SIP/2.0 v: SIP/2.0/UDP 192.168.254.157:5060 t: f: i: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18581 REGISTER Max-Forwards: 70 m: ;dt=544 Expires: 3600 User-Agent: 3Com-SIP-Phone/V8.0.1.3 Authorization: Digest username="sip:[email protected]", realm="asterisk", nonce="6c915c33", uri="sip:192.168.254.12", opaque="", algorithm=MD5, response="a89df25f19e4b4598595f919dac9db81" X-3Com-PhoneInfo: firstRegistration=no; primaryCallP=192.168.254.12; secondaryCallP=0.0.0.0; --- (12 headers 0 lines) --- Using latest REGISTER request as basis request Sending to 192.168.254.157 : 5060 (NAT) SIP/2.0 100 Trying Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18581 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Contact: Content-Length: 0 SIP/2.0 403 Authentication user name does not match account name Via: SIP/2.0/UDP 192.168.254.157:5060;received=192.168.254.157 From: To: ;tag=as3fb867e2 Call-ID: fa4451d8-01d6-1cc2-13e4-00e0bb33beb9 CSeq: 18581 REGISTER User-Agent: Asterisk PBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Content-Length: 0 Scheduling destruction of SIP dialog 'fa4451d8-01d6-1cc2-13e4-00e0bb33beb9' in 32000 ms (Method: REGISTER) Thanks for your input!

  • enabling gzip with htaccess...why is it hit or miss?

    - by adam-asdf
    I have shared hosting through Justhost. I use the HTML5 Boilerplate .htaccess (have tried other methods from here and there without luck) the compression part is as follows: <IfModule mod_deflate.c> # Force deflate for mangled headers developer.yahoo.com/blogs/ydn/posts/2010/12/pushing-beyond-gzipping/ <IfModule mod_setenvif.c> <IfModule mod_headers.c> SetEnvIfNoCase ^(Accept-EncodXng|X-cept-Encoding|X{15}|~{15}|-{15})$ ^((gzip|deflate)\s*,?\s*)+|[X~-]{4,13}$ HAVE_Accept-Encoding RequestHeader append Accept-Encoding "gzip,deflate" env=HAVE_Accept-Encoding </IfModule> </IfModule> # Compress all output labeled with one of the following MIME-types <IfModule mod_filter.c> AddOutputFilterByType DEFLATE application/atom+xml \ application/javascript \ application/json \ application/rss+xml \ application/vnd.ms-fontobject \ application/x-font-ttf \ application/xhtml+xml \ application/xml \ font/opentype \ image/svg+xml \ image/x-icon \ text/css \ text/html \ text/plain \ text/x-component \ text/xml </IfModule> </IfModule> However, it isn't working—at least I don't think—My home page (html) isn't compressing, the CSS and some of the JS aren't gzipped. It is failing on HTML, CSS and JS. However, some things are (or were, who knows what it will look like when you check) gzipped. My domain is http://adaminfinitum.com/ What is weird is that the (Google) PageSpeed browser extension for Firefox (whatever the current version is [Nov. 2012]) gives me a 95% speed rating (and no warnings about compression), yet YSlow and Chrome developer tools both flag me about gzip, as does a tool I found on here while researching this. To reduce cookies I set up a subdomain on my site and I thought maybe that was it so I added an .htaccess there also, but no luck. To reduce http requests I embedded some of webfonts and images in CSS (HTML5 BP stipulates not to compress images, and apparently '.woff' files are already compressed) so I thought maybe that was it and I spent all day separating and asynchronously loading those portions (via Modernizr.load) but that hasn't helped either...if anything it made it worse due to increasing http requests (I realize speed scores of async resources may be misleading). Researching this, it seems to be a fairly common issue but I haven't found an explanation/solution. I don't think it is a MIME-type issue, I have quadruple checked (and thrice edited) my .htaccess files. My hosting company said they run Apache 2.2.22 and I have looked at everything I can find. What gives?

  • Cisco ASA 5505 site to site IPSEC VPN won't route from multiple LANs

    - by franklundy
    Hi I've set up a standard site to site VPN between 2 ASA 5505s (using the wizard in ASDM) and have the VPN working fine for traffic between Site A and Site B on the directly connected LANs. But this VPN is actually to be used for data originating on LAN subnets that are one hop away from the directly connected LANs. So actually there is another router connected to each ASA (LAN side) that then route to two completely different LAN ranges, where the clients and servers reside. At the moment, any traffic that gets to the ASA that has not originated from the directly connected LAN gets sent straight to the default gateway, and not through the VPN. I've tried adding the additional subnets to the "Protected Networks" on the VPN, but that has no effect. I have also tried adding a static route to each ASA trying to point the traffic to the other side, but again this hasn't worked. Here is the config for one of the sites. This works for traffic to/from the 192.168.144.x subnets perfectly. What I need is to be able to route traffic from 10.1.0.0/24 to 10.2.0.0/24 for example.

  • Nginx + PHP-FPM = "Random" 502 Bad Gateway

    - by david
    I am running Nginx and proxying php requests via FastCGI to PHP-FPM for processing. I will randomly receive 502 Bad Gateway error pages - I can reproduce this issue by clicking around my PHP websites very rapidly/refreshing a page for a minute or two. When I get the 502 error page all I have to do is refresh the browser and the page refreshes properly. Here is my setup: nginx/0.7.64 PHP 5.3.2 (fpm-fcgi) (built: Apr 1 2010 06:42:04) Ubuntu 9.10 (Latest 2.6 Paravirt) I compiled PHP-FPM using this ./configure directive ./configure --enable-fpm --sysconfdir=/etc/php5/conf.d --with-config-file-path=/etc/php5/conf.d/php.ini --with-zlib --with-openssl --enable-zip --enable-exif --enable-ftp --enable-mbstring --enable-mbregex --enable-soap --enable-sockets --disable-cgi --with-curl --with-curlwrappers --with-gd --with-mcrypt --enable-memcache --with-mhash --with-jpeg-dir=/usr/local/lib --with-mysql=/usr/bin/mysql --with-mysqli=/usr/bin/mysql_config --enable-pdo --with-pdo-mysql=/usr/bin/mysql --with-pdo-sqlite --with-pspell --with-snmp --with-sqlite --with-tidy --with-xmlrpc --with-xsl My php-fpm.conf looks like this (the relevant parts): ... <value name="pm"> <value name="max_children">3</value> ... <value name="request_terminate_timeout">60s</value> <value name="request_slowlog_timeout">30s</value> <value name="slowlog">/var/log/php-fpm.log.slow</value> <value name="rlimit_files">1024</value> <value name="rlimit_core">0</value> <value name="chroot"></value> <value name="chdir"></value> <value name="catch_workers_output">yes</value> <value name="max_requests">500</value> ... I've tried increasing the max_children to 10 and it makes no difference. I've also tried setting it to 'dynamic' and setting max_children to 50, and start_server to '5' without any difference. I have tried using both 1 and 5 nginx worker processes. My fastcgi_params conf looks like: fastcgi_connect_timeout 60; fastcgi_send_timeout 180; fastcgi_read_timeout 180; fastcgi_buffer_size 128k; fastcgi_buffers 4 256k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; fastcgi_intercept_errors on; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param REDIRECT_STATUS 200; Nginx logs the error as: [error] 3947#0: *10530 connect() failed (111: Connection refused) while connecting to upstream, client: 68.40.xxx.xxx, server: www.domain.com, request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "www.domain.com" PHP-FPM logs the follow at the time of the error: [NOTICE] pid 17161, fpm_unix_init_main(), line 255: getrlimit(nofile): max:1024, cur:1024 [NOTICE] pid 17161, fpm_event_init_main(), line 93: libevent: using epoll [NOTICE] pid 17161, fpm_init(), line 50: fpm is running, pid 17161 [DEBUG] pid 17161, fpm_children_make(), line 403: [pool default] child 17162 started [DEBUG] pid 17161, fpm_children_make(), line 403: [pool default] child 17163 started [DEBUG] pid 17161, fpm_children_make(), line 403: [pool default] child 17164 started [NOTICE] pid 17161, fpm_event_loop(), line 111: ready to handle connections My CPU usage maxes out around 10-15% when I recreate the issue.

  • Cannot login to SQL Server 2008 R2 with Windows authentication

    - by Ian Boyd
    When i try to connect to SQL Server (2008 R2) using Windows authentication: i cannot: Checking the Windows Application event log, i find the error: Login failed for user 'AVATOPIA\ian'. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: ] Log Name: Application Source: MSSQLSERVER Event ID: 18456 Level: Information User: AVATOPIA\ian OpCode: Task Category: Logon i can login to the computer itself using Windows authentication. i can log into SQL Server using the local Windows Administrator account. We can connect to 8 other SQL Servers on the domain using Windows Authentication. Just this one, whitch is the only one that is 2008 R2 is failing. So i assume it's a bug with *2008 R2. Note: i cannot logon locally, or remotely, using Windows authentication. i can login locally and remotely using SQL Server Authentication. Update Note: It's not limited to SQL Server Management Studio, standalone applications that connect using Windows authentication: fail: Note: It's not a client problem, as we can connect fine to other (non-SQL Server 2008 R2 machines): i'm sure there's a technote or knowledge base article describing why SQL Server 2008 R2 is broken by default, but i can't find it. Update 2 Matt figure out the change that Microsoft made so that SQL Server 2008 R2 is broken by default: Administrators are no longer administrators All that remains is to figure out how to make Administrators administrators. One of these days i'm going to start a list of changes around Microsoft's "broken by default" initiative. Steps to reproduce the problem How do i add a group to the sysadmin fixed server role? Here's the steps i try, that don't work: Click Add: Click Object Types: Ensure that you have no ability to add groups: and click OK. Under Enter the object names to select, enter Administrators: Click Check Names, and ensure that you are not allowed to add groups: and click Cancel. Click Browse..., and ensure that you have no ability to add groups: You should now still not have added any group to the sysadmin role. Additional information SQL Server Management Studio is being run as an administrator: SQL Server is set to use Windows Authentication: tried while logged into SQL with both sa and the only other sysadmin domain account (screenshot can be supplied for those who don't believe)

  • Distinction between an extranet and a DMZ

    - by Markus Yrjölä
    I've been reading about intranets, extranets, DMZs and VPNs now, and I'd need some clarifications related to extranets and DMZs. I understand that they are different types of concepts - extranet allows limited access to some intranet resources, while DMZ is a subnet that sits between the internet and intranet and hosts the external-faced services. However, I'd like to know what is their distinction in practice in a usual setup? The Wikipedia article on extranets says that extranets are similar to DMZs because they are used for the same purpose (providing access to some services/resources without exposing the whole intranet). The article also states that an extranet is a part of a VPN, and this TechNet article also states that extranet access is often implemented similarly to remote intranet access, e.g. with a VPN. The TechNet article also says that commonly the extranet is hosted inside the DMZ. This Pearson article says "Although [the DMZ] is technically located within the intranet, [it] can serve as the extranet as well". This is slightly confusing. Consider this scenario: A company has a B2C website hosted in the DMZ. The website can be accessed from anywhere, but requires user authentication. The underlying web app has its database inside the intranet and also interacts with some web services that are hosted inside the intranet (i.e. it accesses intranet resources). The way I see it, the website does effectively offer a restricted access to the intranet. But can it be considered an extranet? If we take the Wikipedia definition of an extranet literally - "An extranet is a computer network that allows controlled access from outside of an organization's intranet" - I think it can. Let's say that the above can't be considered an extranet. What if we change the scenario slightly, and say it's a B2B website, where the access is e.g. limited to connections coming from a specific business partner (by using site-to-site VPN, for example). In this case it surely is an extranet, right? If this is the case, then the difference between extranet services and any other services hosted in the DMZ is simply access restrictions?

  • Communication software wanted: email, sms, IM, phone calls [closed]

    - by user63835
    I am searching for a software solution that integrates / unifies my communication. I use email, instant messaging, SMS and phone. I would like to get all emails, SMS, instant messaging dialogs and meta-data about phone calls into one application. Important is that I can access all past communication with one application. There should be a global address-book to map the communication data to persons or organizations. I want all the communication data in one place to access and backup it easily. The software solution is not required to be multi-user application or server application. It is just for one user (me) only, but server or multi-user applications are not excluded. I may run it on a server hardware. It should run on Linux (Lubuntu / Ubuntu prefered). Free and OpenSource software is prefered. It would be nice if I could perform new communication (like writing a new email, sms, etc.) with one application, but that is not a must have requirement. I could also work with different applications dedicated for different types of communication like IM-application for IM and email-application for email, if all that communication data from the specialized applications will be delivered to one single place where I can access and backup it. I have an android phone and currently I am using Google contacts as the address-book. In the long term this may change, to get back the control over my data. I did some Internet search but did not find a nice solution, yet. If I am looking for unified messaging and unified communication, am I on the right track? The current Thunderbird version has IM functionality integrated. Did not try it, yet. For SMS it may be possible to use an app to send every SMS (incoming and outgoing) as an email, but I am not sure if those SMS-emails can be mapped to an address-book contact. I don't remember exactly, but isn't there a Google android app (I think Google voice) integrating SMS into google services? But in Germany this function has not been released, yet. Maybe a groupware solution would solve the requirements, but I don't have much experience with it. As communication possibilites are groing, I am woundering that there seems to be such a big gap of solutions. I can't believe I am the only one who would like solution, better integrating all the communication channels more easily. If you know a software solution that solves these requirements (partly) I would be glad if you tell me about it. Thanks in advance.

  • Varnish cached 'MISS status' object?

    - by Hesey
    My site uses nginx, varnish, jboss. And some url will be cached by varnish, it depends a response header from jboss. The first time, jboss tells varnish doesn't cache this url. Then the second request, jboss tells varnish to cache, but varnish won't cache it. I used varnishstat and found that 1 object is cached in Varnish, is that the 'MISS status' object? I remove grace code and the problem still exists. When I PURGE this url, varnish works fine and cache the url then. But I can't PURGE so much urls every startup time, how can I fix this? The configuration: acl local { "localhost"; } backend default { .host = "localhost"; .port = "8080"; .probe = { .url = "/preload.htm"; .interval = 3s; .timeout = 1s; .window = 5; .threshold = 3; } } sub vcl_deliver { if (req.request == "PURGE") { remove resp.http.X-Varnish; remove resp.http.Via; remove resp.http.Age; remove resp.http.Content-Type; remove resp.http.Server; remove resp.http.Date; remove resp.http.Accept-Ranges; remove resp.http.Connection; set resp.http.keeplive="true"; } else { if (obj.hits > 0) { set resp.http.X-Cache = "HIT"; } else { set resp.http.X-Cache = "MISS"; } } } sub vcl_recv { if(req.url ~ "/check.htm"){ error 404 "N"; } if( req.http.host ~ "store." || req.request == "POST"){ return (pipe); } if (req.backend.healthy) { set req.grace = 30s; } else { set req.grace = 10m; } set req.http.x-cacheKey = "0"; if(req.url ~ "/shop/view_shop.htm" || req.url ~ "/shop/viewShop.htm" || req.url ~ "/index.htm"){ if(req.url ~ "search=y"){ set req.http.x-cacheKey = req.http.host + "/search.htm"; }else if(req.url !~ "bbs=y" && req.url !~ "shopIntro=y" && req.url !~ "shop_intro=y"){ set req.http.x-cacheKey = req.http.host + "/index.htm"; } }else if(req.url ~ "/search"){ set req.http.x-cacheKey = req.http.host + "/search.htm"; } if( req.http.x-cacheKey == "0" && req.url !~ "/i/"){ return (pipe); } if (req.request == "PURGE") { if (client.ip ~ local) { return (lookup); } else { error 405 "Not allowed."; } } if (req.url ~ "/i/") { set req.http.x-shop-url = req.original_url; }else { unset req.http.cookie; } } sub vcl_fetch { set beresp.grace = 10m; #unset beresp.http.x-cacheKey; if (req.url ~ "/i/" || req.url ~ "status" ){ set beresp.ttl = 0s; /* ttl=0 for dynamic content */ } else if(beresp.http.x-varnish-cache != "1"){ set beresp.do_esi = true; /* Do ESI processing */ set beresp.ttl = 0s; unset beresp.http.set-cookie; } else { set beresp.do_esi = true; /* Do ESI processing */ set beresp.ttl = 1800s; unset beresp.http.set-cookie; } } sub vcl_hash { hash_data(req.http.x-cacheKey); return (hash); } sub vcl_error { if (req.request == "PURGE") { return (deliver); } else { set obj.http.Content-Type = "text/html; charset=gbk"; synthetic {"<!--ve-->"}; return (deliver); } } sub vcl_hit { if (req.request == "PURGE") { set obj.ttl = 0s; error 200 "Purged."; } } sub vcl_miss { if (req.request == "PURGE") { error 404 "N"; } }

  • How to set 2 conditions / criterias for VLOOKUP / LOOKUP / etc in OpenOffice Calc (or Excel)

    - by MestreLion
    I have this spreadsheet that started as a silly aid for a game (Mafia Wars 2), but grew into a tricky spreadsheet question. In the game your character have 9 "slots" for weapons and armors, 1 for each "type": Light Weapon, Heavy Weapon, Body Armor, Head Armor, etc. So I made a list of all weapons and armors available in the game, 1 item per row. Example: SHOP ITEM TYPE ITEM NAME ATK DEF PRICE EQUIPPED? Marketplace Weapon Light Konrad Knife 16 5 5.500 Marketplace Weapon Light Ice Queen 19 6 8.200 Marketplace Armor Body Up Layered Polym 0 31 8.600 Marketplace Armor Body Up Full Shield 7 42 17.650 Marketplace Weapon Heavy Konrad Bullpup 53 25 24.500 Marketplace Weapon Heavy Full Moon Blow 73 12 24.500 x Marketplace Armor Body Low Knee Pads 17 26 14.200 x Marketplace Armor Body Low Army Boots 15 55 24.500 Bone Yard Weapon Light Bone Launcher 41 2 9.400 x Neon Strip Vehicle Ground Supercharged 41 34 24.500 Dead End Weapon Heavy Sharp Sickle 21 5 24.500 Dead End Armor Body Low Unholy Boots 5 36 15.000 Dead End Armor Head Hockey Mask 5 18 15.900 x Last columns is an indication of the items i have already bought and equipped (marked with "x"). What I need is a formula that, for each "slot" (item type), returns info related to the item of that kind that I am using. That would be: ITEM TYPE SHOP NAME ITEM NAME ATK DEF PRICE Weapon Light Bone Yard Bone Launcher 41 2 9.400 Weapon Heavy Marketplace Full Moon Blow 73 12 24.500 Weapon Special -- -- -- -- -- Armor Body Up -- -- -- -- -- Armor Body Low Marketplace Knee Pads 17 26 14.200 Armor Head Dead End Hockey Mask 5 18 15.900 Vehicle Ground -- -- -- -- -- Vehicle Water -- -- -- -- -- Vehicle Air -- -- -- -- -- The item types are fixed, so they can be hard coded. Each row for an item type. So, for 1st result line, it would return data from the row where both 2nd column is "Weapon Light" and last column is "x". Basically I need a LOOKUP (or VLOOKUP, or anything else) that uses 2 criteria to find a given row, the item type and the X marker. Question is: HOW? I am using OpenOffice Calc 3.2.1, but since it shares so many functions with MS Excel, answers for Excel are also fine (as long as it only uses regular formulas, no VBScript or Macros or VBA etc) Last but not least, suggestions / solutions for rearranging the data so it makes this problem easier to solve are also welcome. Thanks!

  • How do I get the latest FastCGI and PHP versions to peacefully coexist on IIS 6?

    - by BHelman
    I have been going round and round trying to get any sort of PHP running on IIS 6. I somehow managed to successfully get version 5.1.4 running using the php5isapi.dll file. However, I want to upgrade a website to begin using a Content Management System. I have never dug into CMS before so I'm open to programs that are easy to use. I am currently looking into TomatoCMS and ImpressCMS - but that's beside the point. I have never done an installation with PHP before and I think I'm getting familiar with how it works. However the current situation is this. Microsoft's Web Platform Installer 2.0 installed FastCGI for me. I need to upgrade to PHP 5.3.1 for a CMS system. So I downloaded the Windows installer and let it go at it. After consulting several other blog articles, I believe I know how it is supposed to work but I am currently not having luck. THE SETUP *.php is a registered extension in IIS 6 for all websites (on Win 2k3). The application that it calls is C:\Windows\system32\inetsvr\fcgiext.dll, like it should. The fcgiext.ini config has the proper lines: [Types] php=PHP [PHP] ext=C:\program files\PHP\php-cgi.exe And the php.ini file also has the correct configs. All extensions are disabled and I changed the correct things for FastCGI. And everything is registered correctly with the PATH variable. Everything is exactly how it should be. BUT when I launch the "info.php" page () on another computer, I get the following error: FastCGI Error The FastCGI Handler was unable to process the request. Error Details: * Section [PHP] not found in config file. * Error Number: 1413 (0x80070585). * Error Description: Invalid index. HTTP Error 500 - Server Error. Internet Information Services (IIS) A quick Google search reveals that I have it all setup correctly as far as the INI's go and the mapping of the php extension. I am completely at a loss. Does anyone have any suggestions? Although the server is hosting three small websites, I don't really care what I have to do to it to get it to work.

  • Getting Classic ASP to work in .js files under IIS 7

    - by Abdullah Ahmed
    I am moving a clients classic asp webapp to a new IIS7 based server. The site contains some .js files which have javascript but also classic asp in <% % tags which contains a bunch of conditional statements designed to spit out pieces of javascript based on session state variables. Here's a brief example of what the file could be like.... var arrHOFFSET = -1; var arrLeft ="<"; var arrRight = ">"; <% If ((Session("dashInv") = "True") And ((Session("systemLevelStaff") = "4") Or (Session("systemLevelCompany") = "4"))) Then %> addMainItem("/MgmtTools/WelcomeInventory.asp?wherefrom=salesMan","",81,"center","","",0,0,"","","","",""); <% Else %> <% If (Session("dashInv") = "False") And ((Session("systemLevelStaff") = "4") Or (Session("systemLevelCompany") = "4")) Then %> <% Else %> addMainItem("/calendar/welcome.asp","",81,"center","","",0,0,"","","","",""); <% End If %> <% End If %> defineSubmenuProperties(135,"center","center",-3,0,"","","","","","",""); Currently this file (named custom.js for example) will start throwing js errors, because the server doesnt seem to recognize the asp code in it and therefore does not parse it. I know I need to somehow specify that a .js file should also be treated like an .asp file and run through parsing it. However I am not sure how to go about doing this. Here is what I've tried so far... Under the Server node in IIS under HANDLER MAPPINGS I created a new Script Map with the following settings. Request Path: *.js Executable: C:\Windows\System32\inetsrv\asp.dll Name: ASPClassicInJSFiles Mapping: Invoke Handler only if request is mapped to : File Verbs: All verbs Access: Script I also created a similar handler under the site node itself. Under MIME Types .js is defined as application/x-javascript None of these work. If I simply rename the file to have .asp extension then things work, however this app is poorly coded and has literally 100's of files with the .js files included in them under various names and locations, so rename, search and replace is the last option I have.

  • Nginx phpmyadmin redirecting to / instead of /phpmyadmin upon login

    - by Frederik Nielsen
    I am having issues with my phpmyadmin on my nginx install. When I enter <ServerIP>/phpmyadmin and logs in, I get redirected to <ServerIP>/index.php?<tokenstuff> instead of <ServerIP>/phpmyadmin/index.php?<tokenstuff> Nginx config file: user nginx; worker_processes 5; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 2; #gzip on; include /etc/nginx/conf.d/*.conf; } Default.conf: server { listen 80; server_name _; #charset koi8-r; #access_log /var/log/nginx/log/host.access.log main; location / { root /usr/share/nginx/html; index index.php index.html index.htm; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # location ~ \.php$ { root /usr/share/nginx/html; try_files $uri =404; fastcgi_pass unix:/tmp/php5-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # location ~ /\.ht { deny all; } location /phpmyadmin { root /usr/share/; index index.php index.html index.htm; location ~ ^/phpmyadmin/(.+\.php)$ { try_files $uri =404; root /usr/share/; fastcgi_pass unix:/tmp/php5-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $request_filename; include fastcgi_params; fastcgi_param PATH_INFO $fastcgi_script_name; } location ~* ^/phpmyadmin/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ { root /usr/share/; } } } (Any general tips on tidying op those config files are accepted too)

  • Port forwarding problem

    - by Steve
    I have a modem connecting to ADSL2 network and a router connecting to the modem. The rest of the machines all connect to the router. The modem has IP as 192.168.1.1 and the router's IP is 192.168.0.1. From the modem configuration, I can see that the modem thinks the router's IP is 192.168.1.2. I can visit the router by either using 192.168.0.1 or 192.168.1.2. Now I forward a port from the router to a private machine. It works. I can test it by typing 192.168.1.2 and it is redirected to the private machine. But if I use 192.168.0.1, it is still the router's configuration page. I also do a port forwarding on my modem. Since the modem sees only the router, I can only forward the port to the router's specific port. And I am thinking that by doing this, I can reach the private machine after two times port forwarding, once on the modem and once on the router. I also have a static public IP. I want to achieve the goal that when someone types the public IP, he will be redirected to the private machine. But when I use some online port forwarding tester, the result always says that the port is closed on the public IP. I have the questions: Why my router has two IPs? Why using one IP I can see the port forwarding result while using the other I cannot? I think the port forwarding only works when visiting from outside, rather than from both outside and inside. Otherwise, if I set port forwarding on my router/modem on port 80, I will never be able to see its original configuration page again. Everything is forwarded. Am I right? How can I achieve my goal described above? By achieve this, I will have a dedicated server of my own and the users can visit from the public IP. Anyone can correct me on any mistakes I made? I am using Netconn modem and D-Link DIR-300 router. Thank you very much for any help. Edit: Consider I have correctly setup the whole thing. Now I want to test my website by using public IP to visit it, but the port forwarding doesn't work. Does it consider that I am inside the local network and not using the port forwarding? If so, how can I do it? I ask my friends (outside my local network) to have a try and they can see the website. What should I do so that from the inside, I can do the testing? Thank you very much.

  • PHP install sqlite3 extension

    - by Kevin
    We are using PHP 5.3.6 here, but we used the --without-sqlite3 command when compiling PHP. (It stands in the 'Configure Command' column). But, it is very risky to recompile PHP on that server; there are many visitors. How can we install/use sqlite3?
