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.

• 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.

• Webcast On-Demand: Building Java EE Apps That Scale

  - by jeckels

  With some awesome work by one of our architects, Randy Stafford, we recently completed a webcast on scaling Java EE apps efficiently. Did you miss it? No problem. We have a replay available on-demand for you. Just hit the '+' sign drop-down for access.Topics include: Domain object caching Service response caching Session state caching JSR-107 HotCache and more! Further, we had several interesting questions asked by our audience, and we thought we'd share a sampling of those here for you - just in case you had the same queries yourself. Enjoy! What is the largest Coherence deployment out there? We have seen deployments with over 500 JVMs in the Coherence cluster, and deployments with over 1000 JVMs using the Coherence jar file, in one system. On the management side there is an ecosystem of monitoring tools from Oracle and third parties with dashboards graphing values from Coherence's JMX instrumentation. For lifecycle management we have seen a lot of custom scripting over the years, but we've also integrated closely with WebLogic to leverage its management ecosystem for deploying Coherence-based applications and managing process life cycles. That integration introduces a new Java EE archive type, the Grid Archive or GAR, which embeds in an EAR and can be seen by a WAR in WebLogic. That integration also doesn't require any extra WebLogic licensing if Coherence is licensed. How is Coherence different from a NoSQL Database like MongoDB? Coherence can be considered a NoSQL technology. It pre-dates the NoSQL movement, having been first released in 2001 whereas the term "NoSQL" was coined in 2009. Coherence has a key-value data model primarily but can also be used for document data models. Coherence manages data in memory currently, though disk persistence is in a future release currently in beta testing. Where the data is managed yields a few differences from the most well-known NoSQL products: access latency is faster with Coherence, though well-known NoSQL databases can manage more data. Coherence also has features that well-known NoSQL database lack, such as grid computing, eventing, and data source integration. Finally Coherence has had 15 years of maturation and hardening from usage in mission-critical systems across a variety of industries, particularly financial services. Can I use Coherence for local caching? Yes, you get additional features beyond just a java.util.Map: you get expiration capabilities, size-limitation capabilities, eventing capabilites, etc. Are there APIs available for GoldenGate HotCache? It's mostly a black box. You configure it, and it just puts objects into your caches. However you can treat it as a glass box, and use Coherence event interceptors to enhance its behavior - and there are use cases for that. Are Coherence caches updated transactionally? Coherence provides several mechanisms for concurrency control. If a project insists on full-blown JTA / XA distributed transactions, Coherence caches can participate as resources. But nobody does that because it's a performance and scalability anti-pattern. At finer granularity, Coherence guarantees strict ordering of all operations (reads and writes) against a single cache key if the operations are done using Coherence's "EntryProcessor" feature. And Coherence has a unique feature called "partition-level transactions" which guarantees atomic writes of multiple cache entries (even in different caches) without requiring JTA / XA distributed transaction semantics.

• A programmer who doesn't get to program - where to turn? [closed]

  - by Just an Anon

  I'm in my mid 20's, and have been working as a full time programmer / developer for the last ~6 years, with several years of part-time freelancing before this, and three straight years of freelancing in the middle of this short career. I work mostly with PHP and the Drupal framework. By and large, I focus on programming custom pieces of functionality; these, of course, vary greatly from project to project. I've got years of solid experience with OOP (have done some Java & C# years ago, too) including intensive experience with front-end development, and even some design work. I've lead small teams (2-4 people) of developers. And of course, given the large amount of freelancing, I've got decent project- & client-management skills. My problem is staying motivated at any place of employment. In the time mentioned I've worked (full-time) at six local companies. The longest I've stayed at any company was just over a year. I find that I'll get hired and be very excited and motivated for the first few months, but the work quickly gets "stale." By that I mean that the interesting components (ie. the programming) get done, and the rest of the work turns into boring cleanup (move a button, add text, change colours, add a field). I don't get challenged, and I don't feel like I'm learning anything new. This happens repeatedly time and time again, and I always end up leaving for either a new opportunity, or to freelance. I'm wondering if perhaps I've painted myself into a corner with the rather niche work market (although with very high demand and good compensation) and need to explore other career choices. Another possibility is that I may be choosing the wrong places of employment, mostly small agencies, and need to look into working for a larger, more established firm. I find programming, writing code, and architecting solutions very rewarding. When I'm working on an interesting problem I lose all sense of time and 14-16 hours can fly by like minutes. I get the same exciting feeling when I'm doing high-level planning of a complex system, breaking up the work and figuring out how everything will tie-in together. I absolutely hate doing small, "stupid" changes that pose no challenge, yet seem to make up more and more of my work. I want to find a workplace where I will get to work on such tasks, be challenged, and improve in all areas of product development. This maybe a programming job, management, architecture of desktop apps, or may be managing a taco stand on a beach in Mexico - I don't know, and I need some advice and real-world feedback. What are some job areas worth exploring? The requirements are fairly simple: working with computers interacting with others challenging decent pay (I'm making just short of 90k / year with a month of vacation & some benefits, and would like to stay in this range, but am willing to take a temporary cut in pay for a more interesting position) Any advice would be much appreciated!

• I thought the new AUTO_SAMPLE_SIZE in Oracle Database 11g looked at all the rows in a table so why do I see a very small sample size on some tables?

  - by Maria Colgan

  I recently got asked this question and thought it was worth a quick blog post to explain in a little more detail what is going on with the new AUTO_SAMPLE_SIZE in Oracle Database 11g and what you should expect to see in the dictionary views. Let’s take the SH.CUSTOMERS table as an example.  There are 55,500 rows in the SH.CUSTOMERS tables. If we gather statistics on the SH.CUSTOMERS using the new AUTO_SAMPLE_SIZE but without collecting histogram we can check what sample size was used by looking in the USER_TABLES and USER_TAB_COL_STATISTICS dictionary views. The sample sized shown in the USER_TABLES is 55,500 rows or the entire table as expected. In USER_TAB_COL_STATISTICS most columns show 55,500 rows as the sample size except for four columns (CUST_SRC_ID, CUST_EFF_TO, CUST_MARTIAL_STATUS, CUST_INCOME_LEVEL ). The CUST_SRC_ID and CUST_EFF_TO columns have no sample size listed because there are only NULL values in these columns and the statistics gathering procedure skips NULL values. The CUST_MARTIAL_STATUS (38,072) and the CUST_INCOME_LEVEL (55,459) columns show less than 55,500 rows as their sample size because of the presence of NULL values in these columns. In the SH.CUSTOMERS table 17,428 rows have a NULL as the value for CUST_MARTIAL_STATUS column (17428+38072 = 55500), while 41 rows have a NULL values for the CUST_INCOME_LEVEL column (41+55459 = 55500). So we can confirm that the new AUTO_SAMPLE_SIZE algorithm will use all non-NULL values when gathering basic table and column level statistics. Now we have clear understanding of what sample size to expect lets include histogram creation as part of the statistics gathering. Again we can look in the USER_TABLES and USER_TAB_COL_STATISTICS dictionary views to find the sample size used. The sample size seen in USER_TABLES is 55,500 rows but if we look at the column statistics we see that it is same as in previous case except  for columns  CUST_POSTAL_CODE and  CUST_CITY_ID. You will also notice that these columns now have histograms created on them. The sample size shown for these columns is not the sample size used to gather the basic column statistics. AUTO_SAMPLE_SIZE still uses all the rows in the table - the NULL rows to gather the basic column statistics (55,500 rows in this case). The size shown is the sample size used to create the histogram on the column. When we create a histogram we try to build it on a sample that has approximately 5,500 non-null values for the column.  Typically all of the histograms required for a table are built from the same sample. In our example the histograms created on CUST_POSTAL_CODE and the CUST_CITY_ID were built on a single sample of ~5,500 (5,450 rows) as these columns contained only non-null values. However, if one or more of the columns that requires a histogram has null values then the sample size maybe increased in order to achieve a sample of 5,500 non-null values for those columns. n addition, if the difference between the number of nulls in the columns varies greatly, we may create multiple samples, one for the columns that have a low number of null values and one for the columns with a high number of null values.  This scheme enables us to get close to 5,500 non-null values for each column. +Maria Colgan

• Programmatically add an ISAPI extension dll in IIS 7 using ADSI?

  - by fretje

  I apologize beforehand, this is a cross post of this SO question. I thought I'd ask it there first, but apparently it doesn't harvest any answers there. I hope it will get more attention here. When I have an answer somewhere, I'll delete the other one. I'm trying to programmatically add an ISAPI extension dll in IIS using ADSI. This has been working for ages on previous versions of IIS, but it seems to fail on IIS 7. I am using similar code like shown in this question: var web = GetObject("IIS://localhost/W3SVC/1/ROOT/specificVirtualDirectory"); var maps = web.ScriptMaps.toArray(); map[maps.length] = ".aaa,c:\\path\\to\\isapi\\extension.dll,1,GET,POST"; web.ScriptMaps = maps.asDictionary(); web.SetInfo(); After executing that code, I do see an "AboMapperCustom-12345678" entry for that specific dll in the "Handler mappings" of the specific virtual directory in which I added the script map. But when I try to use that extension in a browser, I always get HTTP Error 404.2 Not Found The page you are requesting cannot be served because of the ISAPI and CGI Restriction list settings on the Web server. Even after adding an entry to allow that specific dll in the "ISAPI and CGI restrictions", I keep getting that error. To make it actually work, I first have to undo these steps (encountering the same issue like the OP of the question mentioned above: after deleting the script map entry from the IIS manager GUI, I also have to programmatically delete it using ADSI before it's actually gone from the metabase). And then manually add an entry like this: inetmgr - webserver - website - virtual directory - handler mappings - add script map... path = *.dll, executable = <path to dll>, name = <doesn't matter, but it's mandatory> click "yes" on the question "do you want to allow this ISAPI extension?" When I compare the 2 entries, they are exactly the same, except for the "Entry Type" which seems to be "Inherited" for the programmatically added one and "Local" for the one added manually. The strange thing is, even though it says "Inherited", I don't see it anywhere in IIS on a higher level. Where is it inheriting from? In my code, I do add the script map to the specific virtual directory so it should be "Local" as well. Maybe there is the problem, but I don't know how to add a "Local" Script Map using ADSI. I really would like to keep using the ADSI method, as otherwise I will have to use different methods in our setup when working with IIS 7 or previous versions, and I would like to avoid that. To recap: How can I programmatically add a script map entry and its companion CGI and ISAPI restrictions entry to IIS 7 using ADSI? Anybody who can shed some light on this? Any help appreciated.

• Fedora 12 Wireless problems (Intel Wireless 4965AGN Card)

  - by Ninefingers

  Hi All, I'm having an interesting experience with my wireless card at the moment. Basically, it does like this: I connect to the local wireless network (netgear router) It works, briefly, allowing me to browse a webpage or maybe two, if I'm lucky. It then stops working / sending any packets, whilst reported still connected. Now, me being me I've had a look to see what I can find. wpa_supplicant.log looks like this: Trying to associate with valid_mac:a2:30 (SSID='vennardwireless' freq=2462 MHz) Associated with valid_mac:a2:30 WPA: Key negotiation completed with valid_mac:a2:30 [PTK=CCMP GTK=TKIP] CTRL-EVENT-CONNECTED - Connection to valid_mac:a2:30 completed (reauth) [id=0 id_str=] CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys So that's working fine. dmesg | grep "*iwl*" spits out this: iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, 1.3.27kds iwlagn: Copyright(c) 2003-2009 Intel Corporation iwlagn 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 iwlagn 0000:03:00.0: setting latency timer to 64 iwlagn 0000:03:00.0: Detected Intel Wireless WiFi Link 4965AGN REV=0x4 iwlagn 0000:03:00.0: Tunable channels: 13 802.11bg, 19 802.11a channels iwlagn 0000:03:00.0: irq 32 for MSI/MSI-X phy0: Selected rate control algorithm 'iwl-agn-rs' iwlagn 0000:03:00.0: firmware: requesting iwlwifi-4965-2.ucode iwlagn 0000:03:00.0: loaded firmware version 228.61.2.24 Registered led device: iwl-phy0::radio Registered led device: iwl-phy0::assoc Registered led device: iwl-phy0::RX Registered led device: iwl-phy0::TX iwlagn 0000:03:00.0: iwl_tx_agg_start on ra = 00:24:b2:32:a3:30 tid = 0 iwlagn 0000:03:00.0: iwl_tx_agg_start on ra = 00:24:b2:32:a3:30 tid = 0 So that's working too. I can also ping 192.168.0.1 -I wlan0 and arping 192.168.0.1 -I wlan0 the router until the network falls over. uname -r:2.6.32.10-90.fc12.x86_64. Laptop is a Core2 Duo (2Ghz) with 3GB RAM. Other symptoms I've noticed are that wireshark freezes when I capture on the "broken" interface until I disconnect. Am using networkmanager as per normal. Stupidly, I can connect to the same router via eth0/a cat6 cable just fine. Everyone else can connect to the AP fine (from Windows). Yes, I'm sat right next to it and not trying to access a hotspot the other side of the world. Any ideas? Is this a broken update? (I intend to reboot and test an older kernel later)? Anyone else come across this? Edit: iwconfig wlan0 rate auto is the settings I'm using for rates. Also, according to networkmanager the network is still connected. Thanks for any pointers / advice.

• Simple Backup Strategy for Amazon EC2 instances / volumes?

  - by minerj

  You have entered Introductory Backups for Amazon EC2 EBS-backed Windows Images 010... I have been browsing my brains out to find a simple backup strategy for our single windows 2008 server running SharePoint Services. This is an EBS-backed image of one server with one data volume. I don’t need anything exotic. I only need a “daily” backup (losing a day’s worth of data is not catastrophic). We have created and saved an EBS backed AMI image (Windows 2008) we are comfortable using. We started off making backups by simply creating a new EBS AMI image. This is really simple, but the running server is put offline during the first 10 – 15 minutes of creating the image – not ideal. The standard way of creating backups would seem to be creating snapshots of volumes attached to a running instance. Again it’s pretty simple and the server remains usable during the snapshot generation. The apparent Catch-22 is that you can’t simply launch a new instance directly from a snapshot. I know how to bundle a running instance to S3 storage and then register the AMI from the S3 bucket. This does allow me to capture a backup of a running instance and, if the running instance is lost, register the AMI from the S3 bucket and launch the new AMI to recover the instance, but this seems really convoluted and it seems ridiculous to have to juggle back and forth between the AWS Console and the S3 Organizer plug-in for Firefox to get this accomplished. (Please don't mention the command line approach, this is an 010 level course). From playing around with EBS-backed images, the following approach appears to work for me (all done within the AWS Console): 1.For your backups, simply snapshot the system volume (/dev/sda1) as needed. 2.If you lose your running instance, do the following: a.Create a new volume from your last snapshot backup b.Launch another instance of your starting AMI (must be EBS-backed) c.Stop this instance. d.Detach the existing system volume from the new stopped instance and discard. e.Attach the newly created volume as system volume (/dev/sda1) to the stopped instance. f.Re-start the new instance. I have tested this out a couple of times and it seems to work for me. Question: Is there anything wrong with this approach?

• free open-source linux screenshot & ocr tool

  - by Gryllida

  I'm looking for a tool which would be able to capture a screen region, pass it to OCR and put the result into clipboard. "import ppm:- | gocr -i - | xclip -selection c" works, but gocr is unreliable: simple text on a webpage has errors. It is a clear font but the OCR tool always misses "r" and replaces it with underscore. "import ppm:- | ocrad -i - | xclip -selection c" says "ocrad: maxval 255 in ppm "P6" file." tesseract needs an image file and does not accept piping input to it. xfce4-screenshooter does not do OCR. ABBYY Screenshot Reader is proprietary. tessnet2 is freeware running on a proprietary platform. Google Docs can OCR screenshots in a batch. But my data is confidential and better not put online.

• Windows 7 is shutting down unexpectedly, according to the logs.

  - by dlamblin

  Here's a message from my eventvwr EventLog (Windows Logs System): The previous system shutdown at 11:51:15 AM on ?7/?29/?2009 was unexpected. This is funny because I was wondering why the system shut down while I was playing Civilizations IV full screen. Now I know. It was unexpected. Has anyone encountered and resolved this? A little background: I am running Windows 7 RC inside VMWare Fusion 2 (just updated a few months back) on a MacBook (Bitterly not Pro) aluminum-body. Windows 7 occasionally will shut down. This isn't a quick turn-off, it's a shutdown where all the programs are exited, the system waits until they quit (and Civ4 doesn't prompt me to save), it even installed Windows Updates before restarting. And yes it is restarting right after the shutdown. Because I run a game in full screen mode I do not notice any dialog with a countdown timer or anything like that that might be a warning. As I have iStat on my dashboard widgets I can see about 8 temperature monitors. I have seen the CPU get up to 74C before, but during the shutdown, though it seemed hot to the touch (always is), it read 61C for the CPU, 60C for heatsink A, 50C for heatsink B and in the 30s-40s for the enclosure and harddrives. As I type this now, the temps are actually higher, so I don't think the temperature caused it. I have at least six such events dating first from 5/17 which was a week after installing Windows 7. I did find one information level warning from USER32 in the system log that says: The process C:\Windows\system32\svchost.exe (DLAMBLIN-WIN7) has initiated the restart of computer DLAMBLIN-WIN7 on behalf of user NT AUTHORITY\SYSTEM for the following reason: Operating System: Recovery (Planned) Reason Code: 0x80020002 Shutdown Type: restart Comment: And another 15 minutes before that from Windows Update: Restart Required: To complete the installation of the following updates, the computer will be restarted within 15 minutes: - Cumulative Security Update for Internet Explorer 8 for Windows 7 Release Candidate for x64-based Systems (KB972260) Which I think kind of explains it. Though I don't know why restarting after an update would create an error event of "shutdown was unexpected", isn't that pretty odd? Now, how do I set it to never restart after an update unless I click something. Application of solution: As fretje reminded me, there's a couple of configurable settings for this, in windows 7 they're much in the same place as in Windows 2000 SP3 and XP SP1. Running gpedit.msc pops up a window that looks like: Windows 7 has changed the order and added a couple of newer options I've italicized: Do not display 'Install Updates and Shut Down' in Shut Down Windows dialog box Do not adjust default option to 'Install Updates and Shut Down' in Shut Down Windows dialog box Enabling Windows Power Management to automatically wake up the system to install scheduled updates Configure Automatic Updates Specify intranet Microsoft update service location Automatic Updates detection frequency Allow non-administrators to receive update notifications Turn on Software Notifications Allow Automatic Updates immediate installation Turn on recommended updates via Automatic Updates No auto-restart with logged-on users for scheduled Automatic Updates Re-prompt for restart with scheduled installations.

• OpenSSL Handshake Failure (14094410) - Erroneous Client Certificate Check from Mobile Phone

  - by Clayton Sims

  I'm running a proxy server through Apache with modssl, which we're using to proxy POSTs from mobile devices to another internal server. This works successfully for most clients, but requests from a specific phone model (Nokia 2690) are showing a bizarre handshake failure. It looks as though OpenSSL is either requesting (or attempting to read an unsolicited) client certificate from the phone (which is especially bizarre because j2me's kssl implementation doesn't support client certs). I've disabled client certificates with the SSLVerifyClient none directive in both the virtual host conf and the modssl conf. The trace from error.log on debug level is (details redacted): [client 41.220.207.10] Connection to child 0 established (server www.myserver.org:443) [info] Seeding PRNG with 656 bytes of entropy [debug] ssl_engine_kernel.c(1866): OpenSSL: Handshake: start [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: before/accept initialization [debug] ssl_engine_io.c(1882): OpenSSL: read 11/11 bytes from BIO#7fe3fbaf17a0 [mem: 7fe3fbaf90d0] (BIO dump follows) [debug] ssl_engine_io.c(1815): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1860): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1882): OpenSSL: read 49/49 bytes from BIO#7fe3fbaf17a0 [mem: 7fe3fbaf90db] (BIO dump follows) [debug] ssl_engine_io.c(1815): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1860): +-------------------------------------------------------------------------+ [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 read client hello A [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 write server hello A [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 write certificate A [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 write server done A [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 flush data [debug] ssl_engine_io.c(1882): OpenSSL: read 5/5 bytes from BIO#7fe3fbaf17a0 [mem: 7fe3fbaf90d0] (BIO dump follows) [debug] ssl_engine_io.c(1815): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1860): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1882): OpenSSL: read 2/2 bytes from BIO#7fe3fbaf17a0 [mem: 7fe3fbaf90d5] (BIO dump follows) [debug] ssl_engine_io.c(1815): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1860): +-------------------------------------------------------------------------+ [debug] ssl_engine_kernel.c(1879): OpenSSL: Read: SSLv3 read client certificate A [debug] ssl_engine_kernel.c(1898): OpenSSL: Exit: failed in SSLv3 read client certificate A [client 41.220.207.10] SSL library error 1 in handshake (server www.myserver.org:443) [info] SSL Library Error: 336151568 error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure [client 41.220.207.10] Connection closed to child 0 with abortive shutdown (server www.myserver.org:443) I've tried enabling all ciphers and all protocols temporarily with modssl, neither of which seemed to be the issue. The phone should be using RSA_RC4_128_MD5 and SSLv3, all of which are available. Am I missing something more fundamental about what's failing here? It seemed like the certificate request might have been part of a renegotiation failure. I tried enabling SSLInsecureRenegotiation On on the virtual host, in case it was an issue of the phone's SSL not supporting the new protocol, but to no avail.

• Tomcat SPNEGO authentication against Active Directory not working.

  - by Michael

  I'm trying to authenticate against AD using the http://spnego.sourceforge.net component with tomcat. I've created my SPN's "setspn.exe -A HTTP/servername SVCTomcat" & "setspn.exe -A HTTP/servername.fqdn.net SVCTomcat" I've created my krb5.conf & login.conf file and setup the filter in the web.xml ie. <filter-name>SpnegoHttpFilter</filter-name> <filter-class>net.sourceforge.spnego.SpnegoHttpFilter</filter-class> <param-name>spnego.allow.unsecure.basic</param-name> <param-value>false</param-value> <param-name>spnego.login.client.module</param-name> <param-value>spnego-client</param-value> <param-name>spnego.krb5.conf</param-name> <param-value>krb5.conf</param-value> <param-name>spnego.login.conf</param-name> <param-value>login.conf</param-value> <param-name>spnego.preauth.username</param-name> <param-value>SVCTomcat</param-value> <param-name>spnego.preauth.password</param-name> <param-value>Pasword</param-value> <param-name>spnego.login.server.module</param-name> <param-value>spnego-server</param-value> <param-name>spnego.prompt.ntlm</param-name> <param-value>false</param-value> <param-name>spnego.logger.level</param-name> <param-value>2</param-value> Note i've stripped extraneous tags from this, so it's not the actual XML.

It seems the author stopped halfway through his debugging page, so i've no areas to look in other than to triple check my config. Any ideas?

• Excel 2007 VBA macros don't work in Parallels

  - by MindModel

  I've got a complex Excel spreadsheet I need to use at work. My colleagues use the spreadsheet on Windows PC's, with no special configuration required. I want to run it on a MacBook Pro running Snow Leopard. The spreadsheet contains VBA macros which connect to external Oracle db's over the Internet. If I understand correctly, Excel on the Mac doesn't run VBA macros, so I have to use Parallels. I installed Parallels on the Mac and it's running correctly, as far as I can tell. I installed Excel 2007 under Parallels. I can open the Excel spreadsheet in Parallels and click buttons in the spreadsheet to run macros, but the macros fail with compiler errors. I don't have the password to the source code for the VBA macros, and if possible, I don't want to dig in to the code at that level. I know that there are quite a few things that could go wrong, and examining the VBA code might help, but I'm hoping to solve the problem without going down that road. The spreadsheet runs without any special configuration on Windows, so I'm wondering if anyone out there knows of any limitations of Excel VBA macros under Parallels, or anything else I could do to get this spreadsheet working. It's the only thing that's keeping me from using this MacBook Pro at work. Here is the error message: Compile error in hidden module: clsXXXXx0020Toolx0020Ser. This error commonly occurs when code is incompatible with the version, platform, or architecture of this application. Click Help for more info. Compile error in hidden module: A protected module contains a compilation error. Because the error is in a protected module it cannot be displayed. This error commonly occurs when code is incompatible with the version or architecture of this application (for example, code in a document targets 32-bit Microsoft Office applications but it is attempting to run on 64-bit Office). This error has the following cause and solution: Cause of the error: The error is raised when a compilation error exists in the VBA code inside a protected (hidden) module. The specific compilation error is not exposed because the module is protected. Possible solutions: If you have access to the VBA code in the document or project, unprotect the module, and then run the code again to view the specific error. If you do not have access to the VBA code in the document, then contact the document author to have the code in the hidden module updated.

• How to tell if a freebsd jail is up to date?

  - by Martin Torhage

  I've set up a "Service Jail" in FreeBSD 8.0 according to the FreeBSD Handbook (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails-application.html). After upgrading the host to the latest patch level and then performed a jail-upgrade, freebsd-fetch still reports that there are files in need of an update in the jail. Is this expected? Then how do I know if a jail is up to date? This is what I've done in more detail: After the initial setup of the jail freebsd-update fetch reported that there were no updates available neither in the host system nor in the jail. This was expected. A while later freebsd-update fetch reported that the following files where in need of an update both in the host and in the jail. /usr/lib/libssl.a /usr/lib/libssl_p.a /usr/lib/libzpool.a /usr/lib32/libssl.a /usr/lib32/libssl_p.a /usr/lib32/libzpool.a I updated the host and followed the upgrade guide for the jail (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails-application.html#JAILS-SERVICE-JAILS-UPGRADING). freebsd-update fetch now reports that there are no updates available in the host but the following is the output from freebsd-update fetch in the jail: [root@bb /]# freebsd-update fetch Looking up update.FreeBSD.org mirrors... 3 mirrors found. Fetching metadata signature for 8.0-RELEASE from update5.FreeBSD.org... done. Fetching metadata index... done. Inspecting system... done. Preparing to download files... done. The following files are affected by updates, but no changes have been downloaded because the files have been modified locally: /var/db/mergemaster.mtree The following files will be updated as part of updating to 8.0-RELEASE-p2: /usr/lib/libssl.a /usr/lib/libssl_p.a /usr/lib/libzpool.a /usr/lib32/libssl.a /usr/lib32/libssl_p.a /usr/lib32/libzpool.a Shouldn't freebsd-update know that the jail is up to date or have I failed upgrading it? How am I supposed to know if a jail is up to date if freebsd-update can't tell? I'm sure I ran make cleandir twice before make buildworld. TIA

• Linux boot on a raid1 software raid ?

  - by azera

  Hello I am trying to convert my single disk boot to a raid1 boot So far here is what i have: I sucessfully create the raid 1 as degraded with the new drive alone, I copied all the data on it I can mount that raid 1, see its files etc I already have a raid5 that is working on the same box (although not booting on it) I have installed grub on both drive When grub boot, it loads the kernel alright, but during the kernel boot it fails to load the "root block device" The kernel tells me : 1 - detected that root device is an md device 2 - determining root devices 3 - mounting root 4 - mounting /dev/md125 on /newroot failed: input/output error. Please enter another root device: ... At this point, if I enter /dev/sda3 (my "old" root device that isn't converted to raid yet) everything boots fine without the root. The /dev/md125 device is indeed created but it seems to be created after the error happens, as in it creates it after loading the device, when mdadm is loaded.

• Business Owners - What Remote Desktop Solution Do You Use To Service Your Clients PCs?

  - by Sootah

  Howdy fellow computer geeks, I am the owner of a local computer repair business that primarily services its clients on-site. On the occasions that we do service the machines in the office we generally have one of our techs pick the computer up while they are out and about and bring it back with them. Only rarely will we require the customer to bring us the computer themselves. In order to reduce costs, be much more efficient, and potentially expand our market far beyond what would be feasible with travel required; I am looking at ways that we can service our clients remotely whenever possible. What we're in need of is a solid remote desktop application that will be incredibly easy for our customers to connect to, as well as be robust enough that we don't need the client babysitting the computer during the entire repair. Ideally I would like to use a web-based solution so that we don't have to walk the customers through installing, connecting, and configuring it over the phone. This would be unacceptable because of the level of service they are used to. Effectively we'd want them to be able to just go to a URL, enter a PIN or something, and then they are connected and ready to rumble. (Obviously the option to just email them a link that'd do all this for them would be what we'd be aiming for) Along with the ease of use factor, we would need the product to not require any further intervention on the part of the client after we have connected. Nobody is going to be happy if we have to call them every 15 minutes so they can reconnect to us every time we reboot - so auto-reconnect is an absolute must. The only product I know of right now that does any of this is LogMeIn Rescue. It allows unattended access, the applet is lightweight and installs quickly, and the customer can either enter a PIN on the site or just click a link emailed to them in order to connect. The only real downside I see to LogMeIn Rescue is that it's $120.00/month per technician. While we'd ultimately end up saving far more than that per month just in fuel costs alone, I'd like to explore any other options out there that I may not have come across. So - Are there any equally good products out there? If so what are they, why do you recommend them, how have you been utilizing them yourself, and what do they cost? Thanks in advance for your help! -Sootah

• How to allow local LAN access while connected to Cisco VPN?

  - by Ian Boyd

  How can I maintain local LAN access while connected to Cisco VPN? When connecting using Cisco VPN, the server has to ability to instruct the client to prevent local LAN access. Assuming this server-side option cannot be turned off, how can allow local LAN access while connected with a Cisco VPN client? I used to think it was simply a matter of routes being added that capture LAN traffic with a higher metric, for example: Network Destination Netmask Gateway Interface Metric 10.0.0.0 255.255.0.0 10.0.0.3 10.0.0.3 20 <--Local LAN 10.0.0.0 255.255.0.0 192.168.199.1 192.168.199.12 1 <--VPN Link And trying to delete the 10.0.x.x -> 192.168.199.12 route don't have any effect: >route delete 10.0.0.0 >route delete 10.0.0.0 mask 255.255.0.0 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 if 192.168.199.12 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 if 0x3 And while it still might simply be a routing issue, attempts to add or delete routes fail. At what level is Cisco VPN client driver doing what in the networking stack that takes overrides a local administrator's ability to administer their machine? The Cisco VPN client cannot be employing magic. It's still software running on my computer. What mechanism is it using to interfere with my machine's network? What happens when an IP/ICMP packet arrives on the network? Where in the networking stack is the packet getting eaten? See also No internet connection with Cisco VPN Cisco VPN Client interrupts connectivity to my LDAP server Cisco VPN stops Windows 7 Browsing How can I prohibit the creation of a route in Windows XP upon connection to Cisco VPN? Rerouting local LAN and Internet traffic when in VPN VPN Client "Allow local LAN Access" Allow Local LAN Access for VPN Clients on the VPN 3000 Concentrator Configuration Example LAN access gone when I connect to VPN Windows XP Documentation: Route Edit: Things I've not yet tried: >route delete 10.0.* Update: Since Cisco has abandoned their old client, in favor of AnyConnect (HTTP SSL based VPN), this question, unsolved, can be left as a relic of history. Going forward, we can try to solve the same problem with their new client.

• OS X: Finder error -36 when using SMB shares on a Samba server bound to AD

  - by Frenchie

  We're looking at deploying SMB homes on Debian (5.0.3) for our mac clients rather than purchasing four new Xserves. We've got our test servers built and functioning properly. Windows clients behave perfectly, but we've run into an issue with OS X (10.6.x and 10.5.x). We're going this route instead of Windows file servers due to a whole bunch of other issues that arise when going that way. Specifically, when mounting a SMB share with unix extensions switched on and the remote server bound to AD, the finder cannot save files on the share, instead touching the file and then bombing out with a -36 IO error, folder creation is fine. Copying files in the terminal behaves fine and the problem seems to be limited to the finder. The issue arises (I think) as the remote UID/GID is passed across when using unix extensions. OS X uses its own winbind idmap (odsam) to work out the effective UID/GID from AD users and groups whilst we're using a rid map on the server. Consequently, there is a mismatch in ownership which the finder chooses to honour. How OS X appears to handle this is to use the remote uid and gid at the file permission level (see below) and then set an OS X acl granting the local uid/gid to have the appropriate permissions on the file. I think the finder touches the file (which the kernel allows because of the ACL) and then checks the filesystem perms and drops out with the IO error. On a Client fc-003353-d:homes2 root# ls -led test/ drwx------+ 2 135978 100513 16384 Feb 3 15:14 test/ 0: user:jfrench allow list,add_file,search,delete,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,writesecurity,chown,file_inherit,directory_inherit 1: group:ARTS\domain users allow 2: group:everyone allow 3: group:owner allow list,add_file,search,delete,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,writesecurity,chown,file_inherit,directory_inherit,only_inherit 4: group:group allow list,add_file,search,delete,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,writesecurity,chown,file_inherit,directory_inherit,only_inherit 5: group:everyone allow list,add_file,search,delete,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,writesecurity,chown,file_inherit,directory_inherit,only_inherit We've tried the following without any luck: Setting the Linux side file owner to match the OS X GID/UID Adding ACLs on the linux filesystem which grant the OS X GID/UID perms Disabling extended attributes Setting steams=no in /etc/nsmb.conf on the client We're currently running a workaround which is to just turn off unix extensions which forces the macs to just mount the share as the local user with u=rwx perms. This works for most things but is causing a few apps that expect certain perms to break in subtle ways. Worst case scenario is that we'll continue running in this way but we would like to have the unix extensions on. Regards.

• freebsd-update reports an upgraded jail as not upgraded

  - by Martin Torhage

  I've set up a "Service Jail" in FreeBSD 8.0 according to the FreeBSD Handbook (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails-application.html). After upgrading the host to the latest patch level and then performed a jail-upgrade, freebsd-fetch still reports that there are files in need of an update in the jail. Is this expected? Then how do I know if a jail is up to date? This is what I've done in more detail: After the initial setup of the jail freebsd-update fetch reported that there were no updates available neither in the host system nor in the jail. This was expected. A while later freebsd-update fetch reported that the following files where in need of an update both in the host and in the jail. /usr/lib/libssl.a /usr/lib/libssl_p.a /usr/lib/libzpool.a /usr/lib32/libssl.a /usr/lib32/libssl_p.a /usr/lib32/libzpool.a I updated the host and followed the upgrade guide for the jail (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails-application.html#JAILS-SERVICE-JAILS-UPGRADING). freebsd-update fetch now reports that there are no updates available in the host but the following is the output from freebsd-update fetch in the jail: [root@bb /]# freebsd-update fetch Looking up update.FreeBSD.org mirrors... 3 mirrors found. Fetching metadata signature for 8.0-RELEASE from update5.FreeBSD.org... done. Fetching metadata index... done. Inspecting system... done. Preparing to download files... done. The following files are affected by updates, but no changes have been downloaded because the files have been modified locally: /var/db/mergemaster.mtree The following files will be updated as part of updating to 8.0-RELEASE-p2: /usr/lib/libssl.a /usr/lib/libssl_p.a /usr/lib/libzpool.a /usr/lib32/libssl.a /usr/lib32/libssl_p.a /usr/lib32/libzpool.a Shouldn't freebsd-update know that the jail is up to date or have I failed upgrading it? How am I supposed to know if a jail is up to date if freebsd-update can't tell? I'm sure I ran make cleandir twice before make buildworld. TIA

• How to use bzdiff to find difference between 2 bzipped files with diff -I option?

  - by englebip

  I'm trying to do a diff on MySQL dumps (created with mysqldump and piped to bzip2), to see if there are changes between consecutive dumps. The followings are the tails of 2 dumps: tmp1: /*!40101 SET SQL_MODE=@OLD_SQL_MODE */; /*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */; /*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */; /*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */; /*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */; /*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */; /*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */; -- Dump completed on 2011-03-11 1:06:50 tmp2: /*!40101 SET SQL_MODE=@OLD_SQL_MODE */; /*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */; /*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */; /*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */; /*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */; /*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */; /*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */; -- Dump completed on 2011-03-11 0:40:11 When I bzdiff their bzipped version: $ bzdiff tmp?.bz2 10c10 < -- Dump completed on 2011-03-11 1:06:50 --- > -- Dump completed on 2011-03-11 0:40:11 According to the manual of bzdiff, any option passed on to bzdiff is passed on to diff. I therefore looked at the -I option that allows to define a regexp; lines matching it are ignored in the diff. When I then try: $ bzdiff -I'Dump' tmp1.bz2 tmp2.bz2 I get an empty diff. I would like to match as much as possible of the "Dump completed" line, though, but when I then try: $ bzdiff -I'Dump completed' tmp1.bz2 tmp2.bz2 diff: extra operand `/tmp/bzdiff.miCJEvX9E8' diff: Try `diff --help' for more information. Same thing happens for some variations: $ bzdiff '-IDump completed' tmp1.bz2 tmp2.bz2 $ bzdiff '-I"Dump completed"' tmp1.bz2 tmp2.bz2 $ bzdiff -'"IDump completed"' tmp1.bz2 tmp2.bz2 If I diff the un-bzipped files there is no problem: $diff -I'^[-][-] Dump completed on' tmp1 tmp2 gives also an empty diff. bzdiff is a shell script usually placed in /bin/bzdiff. Essentially, it parses the command options and passes them on to diff as follows: OPTIONS= FILES= for ARG do case "$ARG" in -*) OPTIONS="$OPTIONS $ARG";; *) if test -f "$ARG"; then FILES="$FILES $ARG" else echo "${prog}: $ARG not found or not a regular file" exit 1 fi ;; esac done [...] bzip2 -cdfq "$1" | $comp $OPTIONS - "$tmp" I think the problem stems from escaping the spaces in the passing of $OPTIONS to diff, but I couldn't figure out how to get it interpreted correctly. Any ideas? EDIT @DerfK: Good point with the ., I had forgotten about them... I tried the suggestion with the multiple level of quotes, but that is still not recognized: $ bzdiff "-I'\"Dump.completed.on\"'" tmp1.bz2 tmp2.bz2 diff: extra operand `/tmp/bzdiff.Di7RtihGGL'
