• RSS Feeds currently on Simple-Talk

  - by Andrew Clarke

  There are a number of news-feeds for the Simple-Talk site, but for some reason they are well hidden. Whilst we set about reorganizing them, I thought it would be a good idea to list some of the more important ones. The most important one for almost all purposes is the Homepage RSS feed which represents the blogs and articles that are placed on the homepage. Main Site Feed representing the Homepage ..which is good for most purposes but won't always have all the blogs, or maybe it will occasionally miss an article. If you aren't interested in all the content, you can just use the RSS feeds that are more relevant to your interests. (We'll be increasing these categories soon) The newsfeed for SQL articles The .NET section newsfeed The newsfeed for Red Gate books The newsfeed for Opinion articles The SysAdmin section newsfeed if you want to get a more refined feed, then you can pick and choose from these feeds for each category so as to make up your custom news-feed in the SQL section, SQL Training Learn SQL Server Database Administration TSQL Programming SQL Server Performance Backup and Recovery SQL Tools SSIS SSRS (Reporting Services) in .NET there are... ASP.NET Windows Forms .NET Framework ,NET Performance Visual Studio .NET tools in Sysadmin there are Exchange General Virtualisation Unified Messaging Powershell in opinion, there is... Geek of the Week Opinion Pieces in Books, there is .NET Books SQL Books SysAdmin Books And all the blogs have got feeds. So although you can get all the blogs from here..

• Desktop SATA drives in SATA <-> FC array

  - by chris

  Let's assume you've got a box like one of these with space for 24 SATA disks. What are the best bits of advice for deploying this? For instance, should you be greedy and go for the 1.5 or 2tb disks or are they just not reliable enough to be used in an array like this and you should stick with 640gb or 750gb disks instead? Also, I know that FC (or generically, "enterprise class") disks have a different error recovery strategy than desktop disks. An enterprise disk will fail a read quickly and report to the controller that it wasn't able to read that block, and the RAID controller will quickly regenerate the info from the parity disk and mark the block as bad. A desktop disk, on the other hand, will try and try and try again to get the data, and in pathological cases this may cause a raid controller to fail the whole disk because the read operation times out. So there are a couple aspects to this question: What's the best sort of disk to get today? (ie specific disks on the market in Feb 2010) Generically, what should someone look for when trying to buy something like this that kinda walks the line between enterprise and consumer? Lastly -- is there anything that can be done with current "consumer" disks to make them more suitable for array use? IE can you use a SMART configuration to change the error recovery strategy used by the disk? Thanks!

• Gmail: security warning icon

  - by Notetaker

  Hello, I just enabled some Gmail Labs programs in my Gmail account, and then I noticed the orange triangle icon with an exclamation mark in it at the end of the address bar of my Google Chrome browser. Clicking on it brought forth a "Security Information' dialog box, with the following messages: "--mail.google.com The identity of website has been verified by Thawlte SGC CA. --Your connection to mail.google.com is encrypted with 128-bit encryption. However, this page includes other resources which are not secure. These resources can be viewed by others while in transit, and can be modified by an attacker to change the look or behavior of the page." I then logged into two of my other Gmail accounts, one of which has no Gmail Labs programs enabled, and the other with 1 program enabled quite some time ago, both with the same result as above (i.e., with the appearance of the orange triangle warning sign in the address bar). I don't remember seeing the orange triangle before, but I'm not sure if it has ever appeared or not. I have "Always use https" enabled for my Gmail accounts. My questions are: Is there a way to identify and remove these un-secure "resources"? (Could enabling Gmail Labs programs have brought these on?) Meanwhile, are my Gmail accounts compromised and unsafe to use? If so, what should I being doing about that now? After this problem is solved, would I need to reset the password to my Gmail accounts, and/or take any other measures to restore their security? Many thanks for answering my questions!

• SPF hardfail and DKIM failure when recipient has e-mail forwarding

  - by Beaming Mel-Bin

  I configured hardfail SPF for my domain and DKIM message signing on my SMTP server. Since this is the only SMTP server that should be used for outgoing mail from my domain, I didn't foresee any complications. However, consider the following situation: I sent an e-mail message via my SMTP server to my colleague's university e-mail. The problem is that my colleague forwards his university e-mail to his GMail account. These are the headers of the message after it reaches his GMail mailbox: Received-SPF: fail (google.com: domain of [email protected] does not designate 192.168.128.100 as permitted sender) client-ip=192.168.128.100; Authentication-Results: mx.google.com; spf=hardfail (google.com: domain of [email protected] does not designate 192.168.128.100 as permitted sender) [email protected]; dkim=hardfail (test mode) [email protected] (Headers have been sanitized to protect the domains and IP addresses of the non-Google parties) GMail checks the last SMTP server in the delivery chain against my SPF and DKIM records (rightfully so). Since the last STMP server in the delivery chain was the university's server and not my server, the check results in an SPF hardfail and DKIM failure. Fortunately, GMail did not mark the message as spam but I'm concerned that this might cause a problem in the future. Is my implementation of SPF hardfail perhaps too strict? Any other recommendations or potential issues that I should be aware of? Or maybe there is a more ideal configuration for the university's e-mail forwarding procedure? I know that the forwarding server could possibly change the envelope sender but I see that getting messy.

• XNA Notes 004

  - by George Clingerman

  The XNA community has been crazy busy again. It always make me fee like such a slacker collecting all of these notes as I see the tremendous output from people all over the world and it’s incredible and humbling. There are some amazingly skilled people working with XNA. On another not, I’m going to take a minute to get on my soapbox and say, if you are developing ANYTHING and are not using some sort of source/revision control, START IMMEDIATELY. This applies to teams of one. Projects for fun. And “I back up my hard drive” or “I use dropbox!” does NOT count as using source control. You’ll be doing yourself a HUGE favor if you find one, learn to use it and integrate it into your everyday workflow. I personally use Subversion. It’s hosted offsite at xp.dev.com and I use TortoiseSVN as my front end to interface with the repository. It’s simple and easy to use and has saved me from myself so many time. Honestly, get setup with some type of source control immediately. If you don’t understand how, grab another developer that does and have them walk you through setup and the basics of using it. Ok, I’m done.

• Dell Management Packs in System Center Operations Manager 2007 R2?

  - by bwerks

  Hey all, I recently set up SCOM in a small business network environment. The root management server is a Dell Poweredge 2950, and I'd like to use SCOM to monitor it using Dell's management packs. I've imported the management packs into the SCOM deployment and followed Dell's installation instructions, but it doesn't seem to be fully working yet. Currently, the Diagram views in the Dell tree (Monitoring tab) seem to show me the server's place in the network topology, so it seems that at least part of it is working. However, none of the reports under "Performance and Power Monitoring Views" provide any information. When clicking on one of them (Power Consumption (Watts), for instance), the display area is blank and there is a tooltip visible that reads "No performance counter is selected. To select a counter, place a check mark in the Show column in legend below." However, in the legend, there's nothing there for me to check. I've installed OpenManage 6.2 on the server as per the Dell documentation, but I don't know what else I could have done that I missed. Does this sound like a familiar problem to anyone?

• Agile Testing Days 2012 – Day 1 – The birth of the #unicorn…

  - by Chris George

  Still riding the high from the tutorial day, I arrived at the conference venue eager to get cracking with the days talks. The opening Keynote was “Disciplined Agile Delivery: The Foundation for Scaling Agile” presented by Scott Ambler. The general ideas behind the methodology such as not re-inventing the wheel, and being goal driven, not prescriptive in how you work certainly struck chords with how we are trying to work in my team. Scott made some interesting observations about how scrum is quite prescriptive and is this really agile? I agreed with quite a few of his points on how what works for one team may not work for another. How a team works should be driven by context and reflection, not process and prescription. However was somewhat dubious about some of the statistics he rolled out towards the end. However, out of this keynote was born something that was to transcend this one presentation. During the talk, Scott mentioned on more than one occasion “In the real world”, and at one point made reference to people living in the land of unicorns and rainbows. The challenge was then laid down on twitter for all speakers to include a unicorn in their presentations… and for the most part this happened! It became an identity for this years conference, and I’m sure something that any attendee will always associate with Agile Testing Days 2012! Following this keynote, I attended “Going agile with Automated GUI Testing – Some personal insights” by Jan Zdunek from codecentric on the vendor track. My speciality is test automation, and in particular GUI testing, so this drew me to this talk more than the others. Thankfully, it was made clear from the very start that this was not peddling any particular product (even though it was on the vendor track), and Jan faithfully stuck to that. Most of the content was not new to me, but it was really comforting to hear someone else with very similar experiences to my own. In particular, things like how GUI testing is hard and is not a silver bullet; how record & replay is NOT a good thing to do (which drew a somewhat inflammatory tweet from an automation company when I tweeted that!). Something that I have started hearing around the place, and has certainly been murmuring at work is to push more of the automation coding onto the developers. After all they are the coding experts. I agree with this to a degree, but I personally enjoy coding and find it very rewarding doing so, therefore I’d be reluctant to give it up. I think there are some better alternatives such as pairing with a developer. Lastly, Jan mentioned, almost in passing, that we should consider virtualisation for gui testing for covering configuration combinations. On my project we’ve been running our win32/.NET GUI tests in cloud virtualisation for a couple of years now… I really should write about that! After lunch the second keynote of the day was by Lisa Crispin and Janet Gregory,”Myths about Agile Testing, De-Bunked”. It started off well… with the two ladies donning Medusa style head bands whilst they disbanding several myths about agile testing! I got the impression that it was perhaps not as slick as they would have liked, but then Janet was suffering with a very sore throat so kept losing her voice. Nevertheless, the presentation was captivating, and they debunked several myths such as : “Testing is dead”, “Testers must write code”, “Agile teams always deliver faster”. I didn’t take many notes for this because it was being recorded, but unfortunately the recordings have not been posted yet so I’ll write more about this when they are. The TestLab was held during a somewhat free for all time during most of the afternoon. It looked intriguing and proved to be one of the surprising experiences of the conference for me. Run by James Lyndsay and Bart Knaack, it consisted of a number of ‘stations’ that offered different testing problems. I opted for testing a mathematical drawing app call Geogebra, the task being to pair up and exploratory test it. After an allotted time, we discussed issues we’d found and decided if we wanted to continue ‘playing’ to which we all agreed! It was fun! The last track talk of the day was “Developers Exploratory Testing – Raising the bar” by Sigge Birgisson. One of the teams at Red Gate have tried Dev or Team exploratory testing a couple of times, and I was really interested to go to the presentation that prompted that. I was not disappointed! Sigge gave a first class presentation, and not only explained what DET was all about, but also how to go about implementing it. Little tips like calling it a ‘workshop’ rather than ‘testing’ I can really see working! Monday evening saw the presentation of the award for the Most Influential Agile Testing Professional Person go to a much deserved Lisa Crispin. The evening was great, with acrobatics, magic and music. My Takeaway Triple from Day 1:  Some of the cool stuff that was suggested in the GUI Testing talk, we are already doing. I should write about that! Testing is not dead! Perhaps testing will become more of a skill than a specific role, but it is certainly not dead. Team/Developer exploratory testing… seems like a no-brainer assuming you have a team who is willing.  Day 2 – Coming soon…

• Drupal with clean urls turned on is putting question marks in URL

  I have a drupal site with clean urls, the pages load correctly, but then the URL is rewritten with a question mark in it, which I don't want the user to see. My .htaccess is: <IfModule mod_rewrite.c> RewriteEngine on # If your site can be accessed both with and without the 'www.' prefix, you # can use one of the following settings to redirect users to your preferred # URL, either WITH or WITHOUT the 'www.' prefix. Choose ONLY one option: # # To redirect all users to access the site WITH the 'www.' prefix, # (http://example.com/... will be redirected to http://www.example.com/...) # adapt and uncomment the following: # RewriteCond %{HTTP_HOST} ^example\.com$ [NC] # RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301] # # To redirect all users to access the site WITHOUT the 'www.' prefix, # (http://www.example.com/... will be redirected to http://example.com/...) # uncomment and adapt the following: # RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC] # RewriteRule ^(.*)$ http://example.com/$1 [L,R=301] # Modify the RewriteBase if you are using Drupal in a subdirectory or in a # VirtualDocumentRoot and the rewrite rules are not working properly. # For example if your site is at http://example.com/drupal uncomment and # modify the following line: # RewriteBase /drupal # # If your site is running in a VirtualDocumentRoot at http://example.com/, # uncomment the following line: RewriteBase / # Rewrite URLs of the form 'x' to the form 'index.php?q=x'.

• VMware databursts to vCenter

  - by Erwin Blonk

  [edit Nov.16th 2009: Thank you for the responses. I'm no longer on this project so the problem is out of my hands. Be sure I will return with other problems :-) ] I have a strange occurence of regular databursts over my WAN links from 2 sites to a site with vCenter. What happens is that a vCenter server is managing local ESX 3.5 servers and 2 from 2 sites across a WAN link. Each server sends an approximately 3MB worth of TLS data (less than 10% of the time it varies to higher or lower) every 15 minutes (with a margin of 2 minutes). So far, I've not been able to single out a process that causes it. I looked through all applications on each site. So far, it seems to originate from one server on each site. Although it may be coincidence and therefore not relevant, I found that one server, with very few exceptions, does a burst at 00:00 on the hour. The other 3 during the hour are a bit off the 15 minute mark but back at the top of the hour, you can sync your watch on it. The other server follows 5 minutes after that with no such precision. But, as said, it never differs more than 2 minutes. Servers are ESX 3.5, vCenter is 2.5.

• Cygwin, ssh, and git on Windows Server 2008

  - by Paul

  Hi everyone. I'm trying to setup a git repository on an existing Windows 2008 (R2) server. I have successfully installed Cygwin & added git and ssh to the packages, and everything works perfectly (thanks to Mark for his article on it). I can ssh to localhost on the server, and I can do git operations locally on the server. When I try to do either from the client, however, I get the "port 22, Bad file number" error. Detailed SSH output is limited to this: OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007 debug1: Connecting to {myserver} [{myserver}] port 22. debug1: connect to address {myserver} port 22: Attempt to connect timed out without establishing a connection ssh: connect to host {myserver} port 22: Bad file number Google tells me that this means I'm being blocked, usually, by a firewall. So, double-checked the firewall settings on the server, rule is there allowing port 22 traffic. I even tried turning off the firewall briefly, no change in behavior. I can ssh just fine from that client to other servers. The hosting company swears that there's no other firewalls blocking that server on port 22 (or any other port, they claim, but I find that hard to believe). I have another trouble ticket into them, just in case the first support person was full of it, but meanwhile I wanted to see if anyone could think of anything else it can be. Thanks, Paul

• Monitor Exchange Email Address and run scripts

  - by WernerCD

  Okay... Not sure how "out there" this thought is... Right now to send a pager message (aka text message), a user logs into our AS400... logs into the program... enters user name and message and hit's F10 to send. With a little looking, it seems that you can run remote commands to the AS400 via FTP. So I'm working on building a script (batch or otherwise) that, given two parameters (user, message), will FTP into the AS400 and run a remote command: c:\>ftp server user: admin password: ***** ftp> quote rcmd SNDPGRMSG TOPGR(JDOE) MSG('This is a Test') ftp> quit So... what I want to do is setup an email account on our Exchange server Monitor the account for incoming mail upon receipt of incoming mail, parse it... say for example subject is defined as "Recipient" and email text is defined as "Pager message" run a batch that uses the above mentioned TOPGR and MSG as parameters... via FTP to the AS400 mark email as "read" The main thing I'm not sure about is monitoring an exchange account and running a script on incoming emails. I'm sure what I want to do is possible... but where would I start? EDIT: Clarification The main reasons for using this four part system are logging (messages sent via this are logged and reported by the AS400 program) and the existing scheduler for redirecting pages (For example, the weekly on-call person = TOPGR(oncall) gets updated by the AS400 program). I'm also trying to remove duplicate work. If I can get this setup working, I can redirect pages from OTHER systems into this one. I then don't have to update 2, soon to be 3, systems with current phone numbers, carriers, on-call schedules, etc. System #2 and #3 can just "email" [email protected].

• Can't view other computers on Network

  - by Darkart

  Systems: My Machine: Windows 7 Ultimate connected through ethernet into router Her Machine--Other Machine: Windows 7 Ultimate connected through wireless Router:F5D8236-4 N Wireless Router Version 1 Firmware: 2.01.03 (Apr 28 2009) ISP: Comcast Problem: I can not view the "Other Machine" on the network at all. I opened command prompt and ran net view and saw the pc name. I tried pinging the pc and it times out. Went inside the router and tried viewing the computer on the DHCP list and it can not be seen. I restored the router back to default settings and firmware and completely reset the modem and router, and created home group. I went to the other machine to configure home group settings and made sure that both PC's had identical settings. She was able to see my machine but I could not see hers. I restarted both machines and now we cant see each other at all. Also her PC ("Other Machine") had exclamation mark in the wireless icon but was connected just fine. There is no firewalls on currently or anti-virus enabled, and still can not see each other. Right now I am checking for updated drivers for the wireless card, but my question is could it be the router or something hardware related? I have went through all the settings in the Home group and visited most FAQ's and still no luck. Also as it stands I can not view her machine inside the router DHCP Client List :(

I've tried this on my database UPDATE wp_posts set post_content = replace (post_content,'<p> </p>',''); but didn't work. Why? Do I have to add special thinks to consider the space between the <p>and the</p>? Mmm. Good points, both Jon Angliss and Wim. Jon, as you could have guessed, the database shows no entries with that text string. So there's something going on inside the post_content field. Wim, the famous   was replaced previously, but there are still hundreds of posts that for some reason have something different between the p and the /p tags. I've done a search of one of the posts with this error: mysql> select * from wp_posts where post_title like '%3DVisionLive%'; And looking in the wp_content field, this is a little piece of the post: Phil Eisler, responsable de la divisi?n 3D Vision.?</p> <p>?</p> <p>Este portal ser? por tanto No spanish tilde (accent) shown on the terminal, and instead of an space there's a quotation mark between the p and the /p tags. I've tried to replace <p>?</p>, but again, no results. There's some character (or several) there, but I don't know how to discover that. Maybe it's the character set of my terminal, but I've accessed the database from phpmyadmin and in that case there's a space character between the p and the /p. Weird.

• Cisco ASA: Routing packets based on where the connections started from

  - by DrStalker

  We have a Cisco ASA 5505 (version 8.2(2)) with three interfaces: outside: IP address 11.11.11.11, this is the default route inside: IP address 10.1.1.1, this is the local subnet newlink: 22.22.22.22, this is a new internet connection. We need to move VPN users from the 11.11.11.11 address to the 22.22.22.22 address, and we're using SSH on the ASA as to test and sort out the routing. The problem we have is this: If we define a particular IP as being on a static route out the newlink interface then it can SSH to 22.22.22.22 fine. If we do not define a static route then the traffic hits the ASA, but the return traffic does not come back over newlink; presumably it gets sent over the outside interfcae as that is the default route. We can't define a static route for each remote endpoint because there are dialup VPN users, who obviously change IP a lot What we need to do is configure the ASA so if a connection comes in on the newlink interface then the outgoing packets for that go over the newlink interface, not the default route. With iptables this should be do-able by marking the connection and doing mark-routing, but what is the equivalent for a Cisco ASA?

• Juniper router dropping pings to external interface

  - by Alexander Garden

  My organization has a Juniper SSG20-WLAN that routes our traffic to the outside world. We've been having intermittent problems with our internet connection so I wrote up a Python script to ping the internal interface of the router, the external interface, a couple of our internal servers, the ISP router our router talks to, their upstream provider, and Google and Yahoo for good measure. It does that about every minute. What I have found is that when our internet goes out, our Juniper router ceases responding to pings on the external interface. Everything past that is, of course, unreachable. The internal interface and our internal servers continue to echo back without interruption. None of the counters indicate dropped packets of any type. They all look normal. The logs complain about VIP servers being unavailable but otherwise nothing indicative of network issues. My questions are these: Does this exonerate our ISP? Or, contrawise, might a problem with the connection be causing the external interface to go down? Is there somewhere else in the SSG20, beside the system log and counters, that might help me track down info on the problem? UPDATE: Turned out that one of the switches between my monitoring box and the router was a router itself, and occasionally diverting from the gateway to itself. Kudos to those who made suggestions along those lines. Not really sure which answer to mark as accepted, as it was really stuff in the comments that turned out to be right. Thanks for the suggestions.

• Red Hat 5.3 on HP Proliant DL380 G5 and failed drive on RAID controller

  - by thinkdreams

  I have a development ERP server here in my office that I assist with support on, and originally the DBA requested a single drive setup for some of the drives on the server. Thus the hardware RAID controller (an HP embedded controller) looks like: c0d0 (2 drive) RAID-1 c0d1 (2 drive) RAID-1 c0d2 (1 drive) No RAID <-- Failed c0d3 (1 drive) No RAID c0d4 (1 drive) No RAID c0d5 (1 drive) No RAID c0d2 has failed. I replaced the drive immediately with a spare using the hot-swap, but the c0d2 continues to mark itself as failed, even when I umount the partition. I'm loathe to reboot the server since I'm concerned about the server coming back up in rescue mode but I'm afraid that's the only way to get the system to re-read the drive. I assumed there was some sort of auto-detection routine for this, but I haven't been able to figure out the proper procedure. I have installed the HP ACU CLI utilties, so I can see the hardware RAID setup. I'd really like to find out what the proper procedure should have been, where I went wrong, and how to correct it now. Obviously this goes without saying I should NOT have listened to the DBA and set the drives up as RAID-1 throughout as was my first instinct. He wasn't worried about data loss, but it sure would have been easier to replace the failed drive. :)

• Why does `rpm` show 3 httpd packages, and which one provides the real httpd?

  - by Stefan Lasiewski

  I ran yum update on my CentOS5 webserver a few days ago. Today I just noticed that I have 3 httpd-* rpms! How can I end up with three RPMs for httpd (My other servers only have one httpd rpm). I want to make sure that my server has a patched, updated version of /usr/sbin/httpd. How can I tell which one of these packages provides the httpd binary at /usr/sbin/httpd?

• attach / detach mssql 2008 sql server manager [SOLVED]

  - by Tillebeck

  An external consult wrote a guide on how to copy a database. Step two was detach the database using Sql Server Manager. After the detach the database was not visible in the SQL Server Manager... Not much to do but write a mail to the service provider asking to have the database attached again. The service porviders answer: Not posisble to attach again since the SQL Server security has been violated". Rolling back to last backup is not the option I want to use. Can any one give feedback if this seems logic and reasonable to assume that a detached database in a SQL Server 2008 accessed through SQL Server Manager cannot be reattached. It was done by rightclicking the database and choosing detach. -- update -- Based on the comments below I update the question with the server setup. There are two dedicated servers: srv1: Web server with remote desktop and an Sql Server Manager srv2: Sql server that can be accessed through the Sql Server Manager on the web server -- update2 -- After a restart of the server the DBA could suddenly do the attachment of the database. And I guess that after the restart it was a simple task. So all of your answer were rigth! It seems that I can only mark one as a correct answer so I marked the first answer correct. But all are correct answer. Thanks a lot. Without posting the link to this thread then we might had so suffer while watching our database beeing restored by a backup :-) Thanks a lot. BR. Anders

• DHCP forwarding behind access list on a Cisco Catalyst

  - by Ásgeir Bjarnason

  I'm having some trouble with forwarding DHCP from a subnet behind an access list on a Cisco Catalyst 4500 switch. I'm hoping somebody can see the mistake I'm making. The subnet is defined like this: (first three octets of IP addresses and vrf name anonymized) interface Vlan40 ip vrf forwarding vrf_name ip address 10.10.10.126 255.255.255.0 secondary ip address 10.10.10.254 255.255.255.0 ip access-group 100 out ip helper-address 10.10.20.36 no ip redirects I tried turning on a VMWare machine on this subnet that was configured to use DHCP, but I never got a DHCP response and the DHCP server didn't receive a request. I tried putting the following in the access-list: access-list 100 permit udp host 10.10.10.254 host 10.10.20.36 eq bootps access-list 100 permit udp host 10.10.10.254 host 10.10.20.36 eq bootpc access-list 100 permit udp host 10.10.20.36 host 10.10.10.254 eq bootps access-list 100 permit udp host 10.10.20.36 host 10.10.10.254 eq bootpc That didn't help. Can anybody see what the problem is? I know that the DHCP server works; our whole network is running off of this DHCP server I also know that the subnet works because we have active servers running on the network The DHCP scope is already defined on the DHCP server The subnet is correctly defined on the VMWare server (already servers running on the subnet on VMWare) Edit 2012-10-19: This is solved! The subnet had formerly been defined as a /25 network, but was then expanded into a /24 network. When the DHCP scope was altered after this change it was done incorrectly; the gateway was moved to .254, the leasable IP range was in the lower half of the /24 subnet but we forgot to change the CIDR prefix from /25 into /24. This happened some 2 years ago, and we didn't need to use DHCP on this server network again until this week. Thank you MDMarra and Jason Seemann for looking at the question and trying to troubleshoot. Now I'm wondering if I should mark Jason's answer as the accepted answer (I am new to the Stack Exchange network, so I don't know the etiquette of what to do if I misstated the question like in this case).

• Ranking - an Introduction

  - by PointsToShare

  © 2011 By: Dov Trietsch. All rights reserved Ranking Ranking is quite common in the internet. Readers are asked to rank their latest reading by clicking on one of 5 (sometimes 10) stars. The number of stars is then converted to a number and the average number of stars as selected by all the readers is proudly (or shamefully) displayed for future readers. SharePoint 2007 lacked this feature altogether. SharePoint 2010 allows the users to rank items in a list or documents in a library (the two are actually the same because a library is actually a list). But in SP2010 the computation of the average is done later on a timer rather than on-the-spot as it should be. I suspect that the reason for this shortcoming is that they did not involve a mathematician! Let me explain. Ranking is kept in a related list. When a user rates a document the rank-list is added an item with the item id, the user name, and his number of stars. The fact that a user already ranked an item prevents him from ranking it again. This prevents the creator of the item from asking his mother to rank it a 5 and do it 753 times, thus stacking the ballot. Some systems will allow a user to change his rating and this will be done by updating the rank-list item. Now, when the timer kicks off, the list is spanned and for each item the rank-list items containing this id are summed up and divided by the number of votes thus yielding the new average. This is obviously very time consuming and very server intensive. In the 18th century an early actuary named James Dodson used what the great Augustus De Morgan (of De Morgan’s law) later named Commutation tables. The labor involved in computing a life insurance premium was staggering and also very error prone. Clerks with pencil and paper would multiply and add mountains of numbers to do the task. The more steps the greater the probability of error and the more expensive the process. Commutation tables created a “summary” of many steps and reduced the work 100 fold. So had Microsoft taken a lesson in the history of computation, they would have developed a much faster way for rating that may be done in real-time and is also 100 times faster and less CPU intensive. How do we do this? We use a form of commutation. We always keep the number of votes and the total of stars. One simple division gives us the average. So we write an event receiver. When a vote is added, we just add the stars to the total-stars and 1 to the number of votes. We then recomputed the average. When a vote is updated, we reduce the total by the old vote, increase it by the new vote and leave the number of votes the same. Again we do the division to get the new average. When a vote is deleted (highly unlikely and maybe even prohibited), we reduce the total by that vote and reduce the number of votes by 1… Gone are the days of spanning lists, counting items, and tallying votes and we have no need for a timer process to run it all. This is the first of a few treatises on ranking. Even though I discussed the math and the history thereof, in here I am only going to solve the presentation issue. I wanted to create the CSS and Jscript needed to display the stars, create the various effects like hovering and clicking (onmouseover, onmouseout, onclick, etc.) and I wanted to create a general solution with any number of stars. When I had it all done, I created the ranking game so that I could test it. The game is interesting in and on itself, so here it is (or go to the games page and select “rank the stars”). BTW, when you play it, look at the source code and see how it was all done.  Next, how the 5 stars are displayed in the New and Update forms. When the whole set of articles will be done, you’ll be able to create the complete solution. That’s all folks!

• Idle state detection for server

  - by odinmillion

  Windows OS has a service that detects idle state. Details: Task Idle Conditions The computer is considered idle if all the processors and all the disks were idle for more than 90% of the past 15 minutes and if there is no keyboard or mouse input during this period of time. When the Task Scheduler service detects that the computer is idle, the service only waits for user input to mark the end of the idle state. It is very useful for usual PCs that have keyboard amd mouse. We can use standard task scheduler to start some process like defrag when PC in idle state and stop when PC isn't in idle state. But what should we use when we using a standalone server without keyboard and mouse? Server sometimes receives commands by TCP/IP and starts CPU and HDD activity. But sometimes CPU and HDD activity at zero level. I would like to use this periods of time to start defrag or another process. But this started at "idle" state processes should be terminated when another commands will appear. So, standard idle state conditions cant help me because we have not got user input to stop idle state. I need more customizable idle state detector. Automatically started processes shouldn't influence to idle state, but PC should go away from idle state when another process will apperar. What should I use? Maybe exists some advansed task scheduler? Or I should write some useful utility on C#? I hope that it is a standard task and all useful utilities already compiled :)

• VPN on OSX disconnects after precisely 2 minutes and 30 seconds on specific network

  - by Tyilo

  When connecting to my own VPN server on a specific network, called public-network, my Mac disconnects the VPN connection after 2 minutes and 30 seconds. I have performed several tests and this is the result: It works fine until the 2:30 mark It doesn't matter which Mac I use, it still disconnects It doesn't matter which client I use, all of the following does the same: OSX system client, HMA! Pro VPN and Shimo It doesn't matter which protocol I use, at least all of these protocols does the same: PPTP, OpenVPN and L2TP over IPSec The same thing happens using my own VPN server and HMA!'s VPN server. All other clients (Windows/iPhone) can use any of these VPN servers and protocols without problem on public-network On OSX, all the protocols, clients and servers works fine on any other network So it seems that it is the combination of OSX, VPN & public-network that causes this. This is the syslog from my VPN server, when the disconnection happens: Feb 2 12:04:32 raspberrypi pptpd[31400]: CTRL: EOF or bad error reading ctrl packet length.

• Does a 3ware "ECC-ERROR" matter on a JBOD when I have ZFS?

  - by Stefan Lasiewski

  I have a FreeBSD 8.x machine running ZFS and with a 3ware 9690SA controller. The 3ware controller shows an ECC-ERROR with one of the disks: //host> /c0 show VPort Status Unit Size Type Phy Encl-Slot Model ------------------------------------------------------------------------------ p0 OK u0 279.39 GB SAS 0 - SEAGATE ST3300657SS p1 OK u0 279.39 GB SAS 1 - SEAGATE ST3300657SS p2 OK u1 931.51 GB SAS 2 - SEAGATE ST31000640SS p3 ECC-ERROR u2 931.51 GB SAS 3 - SEAGATE ST31000640SS p4 OK u3 931.51 GB SAS 4 - SEAGATE ST31000640SS /c0 show events shows no ECC errors in it's recent history. ZFS does not currently detect any errors. zpool status says No known data errors My question: Is this ECC-ERROR something that I need to be concerned about? According to the 3ware CLI 9.5.2 Manual, an ECC-ERROR means that the 3ware controller caught a read-error for one or more sectors on this drive. This sometimes occurs when a RAID array is recovering from a failed disk. I believe that ECC-ERRORS can also be detected when the 3ware Controller verifies each disk. None of the drives have failed and thus there was no drive rebuild, so I assume that 3ware discovered a bad sector when it ran it's weekly auto-verify scan of the disks. Is this a safe assumption? According to our logs, ZFS has not detected any bad sectors on this drive. ZFS can work around read errors -- if ZFS detects a bad sector on the drive, it will simply mark that sector as bad and never use it again. From the ZFS perspective one bad sector isn't a big deal, although it might indicate that the drive is starting to go bad.
