• OSX: DNS records won't change?

  - by Marko

  I've had two sites on my local host and have had mysite1.local and mysite2.local in my /etc/hosts file to pointing in my localhost. Now, I moved those sites into my homeserver (Ubuntu, Local network) and made changes to hosts file + also in /private/etc/hosts is same. 192.168.0.50 mysite1.local 192.168.0.50 mysite2.local I flushed my dnscache sudo dscacheutil -flushcache rebooted machine, reseted safari but still no changes.. Still if I try to go either mysite1.local or mysite2.local it is pointing to localhost?!? What could be the problem?? OS is Snow Leopard 10.6.8

• How to archive data from a table to a local or remote database in SQL 2005 and SQL 2008

  - by simonsabin

  Often you have the need to archive data from a table. This leads to a number of challenges 1. How can you do it without impacting users 2. How can I make it transactionally consistent, i.e. the data I put in the archive is the data I remove from the main table 3. How can I get it to perform well Points 1 is very much tied to point 3. If it doesn't perform well then the delete of data is going to cause lots of locks and thus potentially blocking. For points 1 and 3 refer to my previous posts DELETE-TOP-x-rows-avoiding-a-table-scan and UPDATE-and-DELETE-TOP-and-ORDER-BY---Part2. In essence you need to be removing small chunks of data from your table and you want to do that avoiding a table scan. So that deals with the delete approach but archiving is about inserting that data somewhere else. Well in SQL 2008 they introduced a new feature INSERT over DML (Data Manipulation Language, i.e. SQL statements that change data), or composable DML. The ability to nest DML statements within themselves, so you can past the results of an insert to an update to a merge. I've mentioned this before here SQL-Server-2008---MERGE-and-optimistic-concurrency. This feature is currently limited to being able to consume the results of a DML statement in an INSERT statement. There are many restrictions which you can find here http://msdn.microsoft.com/en-us/library/ms177564.aspx look for the section "Inserting Data Returned From an OUTPUT Clause Into a Table" Even with the restrictions what we can do is consume the OUTPUT from a DELETE and INSERT the results into a table in another database. Note that in BOL it refers to not being able to use a remote table, remote means a table on another SQL instance. To show this working use this SQL to setup two databases foo and fooArchive create database foo go --create the source table fred in database foo select * into foo..fred from sys.objects go create database fooArchive go if object_id('fredarchive',DB_ID('fooArchive')) is null begin     select getdate() ArchiveDate,* into fooArchive..FredArchive from sys.objects where 1=2       end go And then we can use this simple statement to archive the data insert into fooArchive..FredArchive select getdate(),d.* from (delete top (1)         from foo..Fred         output deleted.*) d         go In this statement the delete can be any delete statement you wish so if you are deleting by ids or a range of values then you can do that. Refer to the DELETE-TOP-x-rows-avoiding-a-table-scan post to ensure that your delete is going to perform. The last thing you want to do is to perform 100 deletes each with 5000 records for each of those deletes to do a table scan. For a solution that works for SQL2005 or if you want to archive to a different server then you can use linked servers or SSIS. This example shows how to do it with linked servers. [ONARC-LAP03] is the source server. begin transaction insert into fooArchive..FredArchive select getdate(),d.* from openquery ([ONARC-LAP03],'delete top (1)                     from foo..Fred                     output deleted.*') d commit transaction and to prove the transactions work try, you should get the same number of records before and after. select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive   begin transaction insert into fooArchive..FredArchive select getdate(),d.* from openquery ([ONARC-LAP03],'delete top (1)                     from foo..Fred                     output deleted.*') d rollback transaction   select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive The transactions are very important with this solution. Look what happens when you don't have transactions and an error occurs   select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive   insert into fooArchive..FredArchive select getdate(),d.* from openquery ([ONARC-LAP03],'delete top (1)                     from foo..Fred                     output deleted.*                     raiserror (''Oh doo doo'',15,15)') d                     select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive Before running this think what the result would be. I got it wrong. What seems to happen is that the remote query is executed as a transaction, the error causes that to rollback. However the results have already been sent to the client and so get inserted into the

• Why use flash to as content headings? Why not?

  - by Itai

  A large number of sites lately which use Flash to replace what would be simple HTML headings (h1, h2, h3). Some of them do it consistently for every header. Why would you do this? What are the pros and cons of this? This seems strange to me and really inefficient, particularly since a page can have dozens of headers. I notice this because I use Flash Block (which temporarily disables Flash), so not everyone may have seen it. Just today I landed here with 4 flash headers. I've seen dozens of such use of Flash this week alone, and I am wondering if this has some benefits.

  - by art.mania

  I need to start using GIT for my projects from now on and I need to use some UNIX commands. but no matter what I do, I always receive "command not found" error. I installed MacPorts, but still cant run any UNIX command :/ When I try ls, I get the error below, same for sudo, or any other command: -bash: ls: command not found and when I try $PATH, I get the lines below: hakan-yilmaz-MacBook-Pro:~ hakanyilmaz$ **$PATH** -bash: /opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/Library/Frameworks/Python.framework/Versions/2.6/bin:/Library/Frameworks/Python.framework/Versions/Current/bin:/opt/subversion/bin/:PATH: No such file or directory I'm on Mac OS X 10.6.6 I spent 2-3 days and kept googling and trying everything I found at forums, but no success. SOLUTION: I opened .bash_profile with TextWrangler and removed everything else than export PATH=/opt/local/bin:/opt/local/sbin:$PATH Then, I reboot that Mac, and WORKING!!!!

• Juju Openstack bundle: Can't launch an instance

  - by user281985

  Deployed bundle:~makyo/openstack/2/openstack, on top of 7 physical boxes and 3 virtual ones. After changing vip_iface strings to point to right devices, e.g., br0 instead of eth0, and defining "/mnt/loopback|30G", in Cinder's block-device string, am able to navigate through openstack dashboard, error free. Following http://docs.openstack.org/grizzly/openstack-compute/install/apt/content/running-an-instance.html instructions, attempted to launch cirros 0.3.1 image; however, novalist shows the instance in

• CentOS 6 - Make system aware of custom lib paths and missing base links

  - by Mike Purcell

  I am trying to compile libmemcached (1.0.7) on CentOS6, and keep getting the following warning: ... checking for event.h... no configure: WARNING: Unable to find libevent ... I manually compiled libevent (2.0.19) and built it using the following configure line: OPTIONS="--prefix=/usr/local/_custom/app/libevent" Everything compiled and installed fine, but I couldn't figure out how to make the system aware that the lib files are in the custom /usr/local/_custom/app/libevent/libdir. I stumbled upon an article and read that I can make the system aware of custom lib paths by adding a custom file to /etc/ld.so.conf.d/ directory: # /etc/ld.so.conf.d/customApp.conf /usr/local/_custom/app/libevent/lib Then I issued the ldconfig command and was able to confirm that libevent was included by issuing this command: ldconfig -p | ack -i libevent Seeing that libevent was now included in the ldconfig output, I figured I would be able to compile libmemcached and satisfy the aforementioned warning. Unfortunately it did not. So I took another look at the ldconfig output and noticed this: libevent_pthreads-2.0.so.5 (libc6,x86-64) => /usr/local/_custom/app/libevent/lib/libevent_pthreads-2.0.so.5 libevent_openssl-2.0.so.5 (libc6,x86-64) => /usr/local/_custom/app/libevent/lib/libevent_openssl-2.0.so.5 libevent_extra-2.0.so.5 (libc6,x86-64) => /usr/local/_custom/app/libevent/lib/libevent_extra-2.0.so.5 libevent_core-2.0.so.5 (libc6,x86-64) => /usr/local/_custom/app/libevent/lib/libevent_core-2.0.so.5 libevent-2.0.so.5 (libc6,x86-64) => /usr/local/_custom/app/libevent/lib/libevent-2.0.so.5 There are no references to the base links, for example, I would expect to see links to these (ls -la /usr/local/_custom/app/libevent/lib): libevent.so -> libevent-2.0.so.5.1.7 libevent_openssl.so -> libevent_openssl-2.0.so.5.1.7 libevent_core.so -> libevent_core-2.0.so.5.1.7 So either I am doing something wrong, or the system still does not know where to look to find libevent.so. -- Update #1 -- I wasn't able to get libmemcached to compile without the warning notice, even after trying to compile using the following configure command: ./configure --prefix=/usr/local/_custom/app/libmemcached CFLAGS="-I/usr/local/_custom/app/libevent/include" LDFLAGS="-L/usr/local/_custom/app/libevent/lib" I thought for sure this would work because I am directly passing the include and lib directories to the configure command. But it did not.

• Setting up subdomain to respond on :443 with apache2

  - by compucuke

  I read through some guides on this and I believe it is possible to have apache respond to a subdomain through ssl. I have domain.com responding on 80 and I do not need domain.com responding on 443. Rather, the only use I have for ssl is for the subdomain sub.domain.com. So my site should be http://domain.com http://www.domain.com https://sub.domain.com https://www.sub.domain.com My CNAME records are as follows sub.domain.com xxx.xx.xx.xxx *.sub.domain.com xxx.xx.xx.xxx The A record exists but should not matter for the example. I set up a separate config file in sites-enabled for sub.domain.com NameVirtualHost xxx.xx.xx.xxx:443 <VirtualHost xxx.xx.xx.xxx:443> SSLEngine on SSLStrictSNIVHostCheck on SSLProtocol -ALL +SSLv3 +TLSv1 SSLCipherSuite ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:-MEDIUM ServerAlias sub.domain.com DocumentRoot /usr/local/www/ssl/documents/ SSLCertificateFile /root/sub.domain.com.crt SSLCertificateKeyFile /root/sub.domain.com.key Alias /robots.txt /usr/local/www/ssl/documents/robots.txt Alias /favicon.ico /usr/local/www/ssl/documents/favicon.ico Alias /js/libs /usr/local/www/ssl/documents/js/libs Alias /media/ /usr/local/www/documents/media/ Alias /img/ /usr/local/www/ssl/documents/img/ Alias /css/ /usr/local/www/ssl/documents/css/ <Directory /usr/local/www/ssl/documents/> Order allow,deny Allow from all </Directory> WSGIDaemonProcess sub.domain.com processes=2 threads=7 display-name=%{GROUP} WSGIProcessGroup sub.domain.com WSGIScriptAlias / /usr/local/www/wsgi-scripts/script.wsgi <Directory /usr/local/www/wsgi-scripts> Order allow,deny Allow from all </Directory> </VirtualHost> Now, it is important to mention that https://domain.com responds with what I have running from script.wsgi above instead of on https://sub.domain.com. It does not respond to sub.domain.com. checking https://sub.domain.com causes a 105 error. This is a DNS error but I am convinced the DNS does not have a problem with the CNAME records, they just point to my IP. Am I doing something that Apache can not do?

• What does a status of "Backup" mean for Windows 7 local user profiles?

  - by Howiecamp

  Summary: Upon logging on to Windows 7 RTM I get a message that my profile can't be loaded and a temporary user profile is created. I logged off and back on as Administrator. The user profiles dialog shows my user profile with a Type of "Local" and a Status of "Backup" rather than "Local" which it should be. How can I change this to make my user profile accessible? The long story: My PC has a single hard drive partitioned into a C: and a D:. I'd moved my user profile directory (c:\Users) to d:\Users, removed c:\Users and then used mklink.exe to create a directory symbolic link c:\Users -- d:\Users. Worked like a charm since I did it. Today, I make a System Restore Point for drives C: and D:. Next, I dismounted D: and used the Disk Management tool to remove the "D:" drive letter from the D volume. (My plan was to reboot and then redirect the symbolic link.) Upon reboot, I got the user profile error described above. Finally, I restored the System Restore Points that I'd created for both drives and then rebooted again. Same issue.

• Python install issue on Mac OS X

  - by Michael Waterfall

  I have been using the standard python that comes with OS X Lion (2.7.2) but I wanted to build a UCS-4 version to handle 4-byte unicode characters better. I had already installed pip and packages like pytz, virtualenv and virtualenvwrapper, etc., and these are installed in /Library/Python/2.7/site-packages. My $PATH is /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin. To build a new version of python on the machine (outside of any project specific virtual environments, that will come later), I followed the instructions on this article and managed to build it in /usr/local/bin. The problem is that when I launched a new bash window, I got the following virtualenvwrapper error: Traceback (most recent call last): File "<string>", line 1, in <module> ImportError: No module named virtualenvwrapper.hook_loader virtualenvwrapper.sh: There was a problem running the initialization hooks. If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenv has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python and that PATH is set properly. The instructions said to move /usr/local/bin to the top of the /etc/paths file, and since then I've noticed some strange issues. I installed pip into /usr/local/bin and now I have assumed that since I'm working in /usr/local/bin, and the newly installed python's site packages is now located in /usr/local/lib/python2.7/site-packages, when I do pip freeze, it should be empty as nothing is installed there yet. However, pip freeze still reports things installed in the old (OS X) site-packages folder. Here's some info after the build: $ which python /usr/local/bin/python $ which pip /usr/local/bin/pip $ echo $PATH /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin When I uninstall a python package with pip, it removes it from the old site-packages folder as expected. When I install it again, instead of installing it in /usr/local/lib/python2.7/site-packages, it installs it in /Library/Python/2.7/site-packages (verified by attempting to install it again and receiving Requirement already satisfied (use --upgrade to upgrade): pytz in /Library/Python/2.7/site-packages ). How is it getting that path for the old site-packages folder? Why won't it install it in the correct location for the python install it's using? I'm getting several other issues since promoting /usr/local/bin but I think if I understand this I'll be able to get somewhere. Can anyone see what's happening? If you need any more info I'll be happy to provide it.

• How can I install Insight debugger?

  - by DandyWalker

  Hello. I am following along a book in which Insight debugger is required. I didn't find it on my Maverick. I googled and I found that it's not supported in debian anymore but I really need to install it. I tried to compile the source and it installed but keep telling me that tk is missing whenever i start it. I installed tk with sudo aptitude install tk then tried to run again it's the same. I compiled it one more time and nothing really changes. So please how can I install that ? Update: This is the message i get Tk_Init failed: Can't find a usable tk.tcl in the following directories: /usr/local/share/tk8.4 /usr/local/lib/tk8.4 /usr/lib/tk8.4 /usr/local/library /usr/library /usr/tk8.4.1/library /tk8.4.1/library /usr/local/share/tk8.4/tk.tcl: no event type or button # or keysym no event type or button # or keysym while executing "bind Listbox <MouseWheel> { %W yview scroll [expr {- (%D / 120) * 4}] units }" (file "/usr/local/share/tk8.4/listbox.tcl" line 182) invoked from within "source /usr/local/share/tk8.4/listbox.tcl" (in namespace eval "::" script line 1) invoked from within "namespace eval :: [list source [file join $::tk_library $file.tcl]]" (procedure "SourceLibFile" line 2) invoked from within "SourceLibFile listbox" (in namespace eval "::tk" script line 4) invoked from within "namespace eval ::tk { SourceLibFile button SourceLibFile entry SourceLibFile listbox SourceLibFile menu SourceLibFile panedwindow SourceLibFile ..." invoked from within "if {$::tk_library ne ""} { if {[string equal $tcl_platform(platform) "macintosh"]} { proc ::tk::SourceLibFile {file} { if {[catch { namesp..."

• Which Java web framework do you recommend for intranet webapp (not content website)?

  - by pregzt

  I'm about to start development of small purpose build intranet web application for small software vendor. It will be administration console of the server managing licenses for off-the-shelf software installed by users. There will be a few users who need to be able to sign in, issue a batch of license codes, revoke some, renew outdated, resolve issues, etc. Bear in mind that my customer requires Java for this solution. I'm seasoned Java programmer and before I used different frameworks to implement webapps, mainly Apache Struts in the past and Spring MVC recently. I was wondering what else could you recommend for such specific intranet webapp. I looked at using Google Web Toolkit (possibly with SmartGWT) Ext JS for fancy widgets in UI and REST back-end in SpringMVC SpringMVC with JQueryUI Could you please think of any piece of recommendation with regard to the choice I'm going to made?

• Has anyone been able to convert a site's media content from flash to html5?

  - by Muhammad

  I'm looking to convert a site from Flash based video to HTML5, the current video uses time marks to display slides (kind of like how youtube has ads on their videos). But the difference between Youtube and my site is that it doesn't show up inside the video, the slides are displayed next to the video. Is there any way I can accomplish this with HTML5? Or do I have to use Javascript for this? If this isn't clear enough, please let me know.

• Is it better to load up a class with methods or extend member functionality in a local subclass?

  - by Calvin Fisher

  Which is better? Class #1: public class SearchClass { public SearchClass (string ProgramName) { /* Searches LocalFile objects, handles exceptions, and puts results into m_Results. */ } DateTime TimeExecuted; bool OperationSuccessful; protected List<LocalFile> m_Results; public ReadOnlyCollection<LocalFile> Results { get { return new ReadOnlyCollection<LocalFile>(m_Results); } } #region Results Filters public DateTime OldestFileModified { get { /* Does what it says. */ } } public ReadOnlyCollection<LocalFile> ResultsWithoutProcessFiles() { return new ReadOnlyCollection<LocalFile> ((from x in m_Results where x.FileTypeID != FileTypeIDs.ProcessFile select x).ToList()); } #endregion } Or class #2: public class SearchClass { public SearchClass (string ProgramName) { /* Searches LocalFile objects, handles exceptions, and puts results into m_Results. */ } DateTime TimeExecuted; bool OperationSuccessful; protected List<LocalFile> m_Results; public ReadOnlyCollection<LocalFile> Results { get { return new ReadOnlyCollection<LocalFile>(m_Results); } } public class SearchResults : ReadOnlyCollection<LocalFile> { public SearchResults(IList<LocalFile> iList) : base(iList) { } #region Results Filters public DateTime OldestFileModified { get { /* Does what it says. */ } } public ReadOnlyCollection<LocalFile> ResultsWithoutProcessFiles() { return new ReadOnlyCollection<LocalFile> ((from x in this where x.FileTypeID != FileTypeIDs.ProcessFile select x).ToList()); } #endregion } } ...with the implication that OperationSuccessful is accompanied by a number of more interesting properties on how the operation went, and OldestFileModified and ResultsWithoutProcessFiles() also have several more siblings in the Results Filters section.

• Should be simple: existing laptop with local user and outlook 2007 migrate on same computer to domain user with outlook 2007 emails intact

  - by bifpowell

  I have Dell Laptop with windows 7 64 bit and for the last year it's been just a machine with an account like: machine\john there are files in folders and stuff in c:\users\john and john uses outlook 2007 as a pop3 client and has identifiable local appdata pst files. Now I installed a server and want to have everything be domain-centric so I added this laptop to the domain with admin credentials and then logged in as a domain user as: domain\john.smith Now I want to duplicate machine\john (outlook emails mostly) to domain\john.smith. In the past I used the Files and Settings Xfer Wizard and done. I tried that here and it crunched away for a while, made the file, but the restore had no effect - it ran for a while, had a progress bar, but it's like nothing happened at all afterwards. I've rebooted the machine, logged in as domain administrator as the first user to log on after the restart and tried: c:\users\john xcopy c:\users\john c:\users\john.smith /V /C /F /H /K /Y /E ...and it copies some of it, but when it gets to c:\users\john.smith\appdata\local\application data it chokes "Access denied, unable to create directory" I also tried logging in as domain\john.smith and copying the entire directory that the PSTs are in from machine\john and a lot of the mail was there when I launched outlook after replacing the PSTs, but not all of them??? I got errors about files in use when doing this method, which I figure must be why not all the old emails are in the inbox?... There must be some extremely simple way to do what must be a very common requirement. Any guidance appreciated.

• Setup staging with multiple SVN

  - by Kapil Sharma

  We are a startup, setting new environments for product to be released soon. Planned server structure with planned release flow is as shown in below image It ideally have a local server (or Staging server, shown in green) in local office, without public IP address and Production Server (Red) at Amazon EC2. Both local and production server have there own SVN copy. Management here want to update production server with production SVN and without providing its access to developers (including freelancers/contract employees). So for developers, there is a Local SVN on local server. Another purpose of local SVN to keep a copy of code on local server, which is under our direct control. Although there are some technical concerns like how will code at local server will be updated from local SVN and commit on production SVN but bigger question is, is that structure correct? Major requirement remain don't provide production SVN access to developers. What are other possible options to achieve that? Another minor question, if suitable here, if above structure is correct, is it possible for a SVN checkout to get updated from one SVN (Local SVN) but commit to other (Production SVN)? If yes, How? edit An answer has been accepted but for bounty, I'm still looking for answer Is that structure correct? Its pros/Cons? Technical solution is already provided by accepted answer.

• How do I format a text file for IIS Mailroot Pickup so that it sends an e-mail with attachments?

  - by Ben McCormack

  How do I need to format a text file so that it can be read by an SMTP service to send an e-mail that has an attachment? We have a server where we are using II6 SMTP to send mail from a Pickup folder. The goal is to drop a properly formatted text file into Mailroot\Pickup and then the file will be automatically processed and sent to the correct SMTP recipient. For simple files, this works correctly. Here's an example of a simple file that works (domain names changed): From:[email protected] To:[email protected] Subject:Hello World! Test Body Of The E-mail When I drop a text file containing the above contents into the Mailroot\Pickup folder, it sends correctly. However, I haven't been able to figure out how to get an attachment to work. I found some material that explained how to encode an SMTP attachment and another tool for simple base64 encoding conversion. Using the information on those pages, I came up with the following text: From:[email protected] To:[email protected] Subject:Hello World! MIME-Version: 1.0 Content-Type: text/plain; boundary="Attached" Content-Disposition: inline; --Attached Content-Transfer-Encoding: base64 Content-Type: text/plain; name="attachment.txt" Content-Disposition: attachment; filenamename="attachment.txt" VGhpcyBpcyBhIHRlc3Qgb2Ygc29tZXRoaW5nIHRvIGVuY29kZS4NCk5ldyBsaW5lDQpOZXcgTGlu ZQ0KIkhlbGxvdyIgISEhDQo9PT09ICcgZnNkZnNkZiAxMjM1NDU2MzQzNA== --Attached-- However, when I place the above text in a file and drop it into Mailroot\Pickup, it doesn't send an attachment correctly. Instead, an e-mail shows up with the following in the body of the e-mail: MIME-Version: 1.0 Content-Type: text/plain; boundary="Attached" Content-Disposition: inline; --Attached Content-Transfer-Encoding: base64 Content-Type: text/plain; name="attachment.txt" Content-Disposition: attachment; filenamename="attachment.txt" VGhpcyBpcyBhIHRlc3Qgb2Ygc29tZXRoaW5nIHRvIGVuY29kZS4NCk5ldyBsaW5lDQpOZXcgTGlu ZQ0KIkhlbGxvdyIgISEhDQo9PT09ICcgZnNkZnNkZiAxMjM1NDU2MzQzNA== --Attached-- I can't figure out what I need to do to format the text file so that the SMTP service correctly sends attachments.

• I have UFW block messages from local network machines, how can I analyse if they are malicious?

  - by Trygve

  I'm getting a lot of messages in my UFW log, and I'm trying to figure out if these are malicious or just normal. A UDP broadcast is coming from a windows laptop x.x.x.191, and some from our synology disks x.x.x.{6,8,10,11}. I have not figured out which macine 114 is yet.

• How do you set up the directory structure for a multilingual site without duplicating content?

  - by Ricardo

  I want to make a website in two languages. I've looked around and settled on the directory option of separating both languages. How do I make it work? Let's say I have the following three files for the landing homepage, the English page and the Spanish page: http://www.domain.com/index.html http://www.domain.com/en/index.html http://www.domain.com/es/index.html Let's also say that /index.html will be in English, with a link to /es/index.html. In turn, /es/index.html will have a link to the English version. Would this be back to /index.html or to /en/index.html. How do I get both English versions (the one at the root and the one in the directory) to actually be the same file in the same directory? I'm new to this, so I'm not using any scripts yet. To me, the obvious solution is to duplicate both English versions and have the one at the root point to files under the /en/ directory, but I'm not a fan of duplication and I've learned that search engines really frown upon that. Anyone point me in the right direction?

• What would be the best approach to make revisions of user content?

  - by Kevin Simper

  I have searched and could not find any information about it. What is the best approach to storing revisions? I have a website where the user can write a document which can be fairly long (200-300 lines). How do you determine when to make a revision? Is it not a scalable solution to make a new one whenever the save, because that would be useless to the user when the want to look back, and it would require quite a lot of space. You could use time and say for every 15 minute they are working on it there would be a revision, but that would sometimes be nothing or the whole document have completely changed. I could make a diff from the previous revision, and compare by line and look at how many percent of the lines have been changed. What are other doing revisions?

• Stop duplicate icmp echo replies when bridging to a dummy interface?

  - by mbrownnyc

  I recently configured a bridge br0 with members as eth0 (real if) and dummy0 (dummy.ko if). When I ping this machine, I receive duplicate replies as: # ping SERVERA PING SERVERA.domain.local (192.168.100.115) 56(84) bytes of data. 64 bytes from SERVERA.domain.local (192.168.100.115): icmp_seq=1 ttl=62 time=113 ms 64 bytes from SERVERA.domain.local (192.168.100.115): icmp_seq=1 ttl=62 time=114 ms (DUP!) 64 bytes from SERVERA.domain.local (192.168.100.115): icmp_seq=2 ttl=62 time=113 ms 64 bytes from SERVERA.domain.local (192.168.100.115): icmp_seq=2 ttl=62 time=113 ms (DUP!) Using tcpdump on SERVERA, I was able to see icmp echo replies being sent from eth0 and br0 itself as follows (oddly two echo request packets arrive "from" my Windows box myhost): 23:19:05.324192 IP myhost.domain.local > SERVERA.domain.local: ICMP echo request, id 512, seq 43781, length 40 23:19:05.324212 IP SERVERA.domain.local > myhost.domain.local: ICMP echo reply, id 512, seq 43781, length 40 23:19:05.324217 IP myhost.domain.local > SERVERA.domain.local: ICMP echo request, id 512, seq 43781, length 40 23:19:05.324221 IP SERVERA.domain.local > myhost.domain.local: ICMP echo reply, id 512, seq 43781, length 40 23:19:05.324264 IP SERVERA.domain.local > myhost.domain.local: ICMP echo reply, id 512, seq 43781, length 40 23:19:05.324272 IP SERVERA.domain.local > myhost.domain.local: ICMP echo reply, id 512, seq 43781, length 40 It's worth noting, testing reveals that hosts on the same physical switch do not see DUP icmp echo responses (a host on the same VLAN on another switch does see a dup icmp echo response). I've read that this could be due to the ARP table of a switch, but I can't find any info directly related to bridges, just bonds. I have a feeling my problem lay in the stack on linux, not the switch, but am opened to any suggestions. The system is running centos6/el6 kernel 2.6.32-71.29.1.el6.i686. How do I stop ICMP echo replies from being sent in duplicate when dealing with a bridge interface/bridged interfaces? Thanks, Matt [edit] Quick note: It was recommended in #linux to: [08:53] == mbrownnyc [gateway/web/freenode/] has joined ##linux [08:57] <lkeijser> mbrownnyc: what happens if you set arp_ignore to 1 for the dummy interface? [08:59] <lkeijser> also set arp_announce to 2 for that interface [09:24] <mbrownnyc> lkeijser: I set arp_annouce to 2, arp_ignore to 2 in /etc/sysctl.conf and rebooted the machine... verifying that the bits are set after boot... the problem is still present I did this and came up empty. Same dup problem. I will be moving away from including the dummy interface in the bridge as: [09:31] == mbrownnyc [gateway/web/freenode/] has joined #Netfilter [09:31] <mbrownnyc> Hello all... I'm wondering, is it correct that even with an interface in PROMISC that the kernel will drop /some/ packets before they reach applications? [09:31] <whaffle> What would you make think so? [09:32] <mbrownnyc> I ask because I am receiving ICMP echo replies after configuring a bridge with a dummy interface in order for ipt_netflow to see all packets, only as reported in it's documentation: http://ipt-netflow.git.sourceforge.net/git/gitweb.cgi?p=ipt-netflow/ipt-netflow;a=blob;f=README.promisc [09:32] <mbrownnyc> but I do not know if PROMISC will do the same job [09:33] <mbrownnyc> I was referred here from #linux. any assistance is appreciated [09:33] <whaffle> The following conditions need to be met: PROMISC is enabled (bridges and applications like tcpdump will do this automatically, otherwise they won't function). [09:34] <whaffle> If an interface is part of a bridge, then all packets that enter the bridge should already be visible in the raw table. [09:35] <mbrownnyc> thanks whaffle PROMISC must be set manually for ipt_netflow to function, but [09:36] <whaffle> promisc does not need to be set manually, because the bridge will do it for you. [09:36] <whaffle> When you do not have a bridge, you can easily create one, thereby rendering any kernel patches moot. [09:36] <mbrownnyc> whaffle: I speak without the bridge [09:36] <whaffle> It is perfectly valid to have a "half-bridge" with only a single interface in it. [09:36] <mbrownnyc> whaffle: I am unfamiliar with the raw table, does this mean that PROMISC allows the raw table to be populated with packets the same as if the interface was part of a bridge? [09:37] <whaffle> Promisc mode will cause packets with {a dst MAC address that does not equal the interface's MAC address} to be delivered from the NIC into the kernel nevertheless. [09:37] <mbrownnyc> whaffle: I suppose I mean to clearly ask: what benefit would creating a bridge have over setting an interface PROMISC? [09:38] <mbrownnyc> whaffle: from your last answer I feel that the answer to my question is "none," is this correct? [09:39] <whaffle> Furthermore, the linux kernel itself has a check for {packets with a non-local MAC address}, so that packets that will not enter a bridge will be discarded as well, even in the face of PROMISC. [09:46] <mbrownnyc> whaffle: so, this last bit of information is quite clearly why I would need and want a bridge in my situation [09:46] <mbrownnyc> okay, the ICMP echo reply duplicate issue is likely out of the realm of this channel, but I sincerely appreciate the info on the kernels inner-workings [09:52] <whaffle> mbrownnyc: either the kernel patch, or a bridge with an interface. Since the latter is quicker, yes [09:54] <mbrownnyc> thanks whaffle [edit2] After removing the bridge, and removing the dummy kernel module, I only had a single interface chilling out, lonely. I still received duplicate icmp echo replies... in fact I received a random amount: http://pastebin.com/2LNs0GM8 The same thing doesn't happen on a few other hosts on the same switch, so it has to do with the linux box itself. I'll likely end up rebuilding it next week. Then... you know... this same thing will occur again. [edit3] Guess what? I rebuilt the box, and I'm still receiving duplicate ICMP echo replies. Must be the network infrastructure, although the ARP tables do not contain multiple entries. [edit4] How ridiculous. The machine was a network probe, so I was (ingress and egress) mirroring an uplink port to a node that was the NIC. So, the flow (must have) gone like this: ICMP echo request comes in through the mirrored uplink port. (the real) ICMP echo request is received by the NIC (the mirrored) ICMP echo request is received by the NIC ICMP echo reply is sent for both. I'm ashamed of myself, but now I know. It was suggested on #networking to either isolate the mirrored traffic to an interface that does not have IP enabled, or tag the mirrored packets with dot1q.

• Possible to host CentOS netinstall files on a local HTTP/FTP?

  - by garlicman

  I'm running XenServer on an Dell R610 and am running into a catch-22. During install from DVD, CentOS can't find the DVD package catalogue. It's a reported error for some, XenServer + CentOS6 + DVD install in some hardware configurations = failed install. Yes, I checked the MD5 and let the disc test pass. In every reported case, the netinstall was the solution. The issue is my net access is required to go through a web proxy that prompts before you can download a file. This naturally breaks any download automation. I've been waiting on our IT to put in an exception rule to allow my lab to bypass the prompt, but it's been over 3 weeks now and they don't seem responsive. (I've been working on this a day or two a week) I want to try and host the netinstall files local in my Xen network. Right now I only have a bunch of Windows based VMs, CentOS won't install so I don't have any Linux tools. I had tried simply hosting all the DVD contents off one of the Windows servers using Mongoose. (I didn't want to setup IIS) I copied them to a hosted sub-directory similar to all the mirrors out there (e.g. http:///centos/6.2/os/i386/) with no auth or anything. Then in the netinstall I correctly pointed to it. I now realize just copying the DVD files over won't work. The repodata will point to a local device, not the site I'm hosting. (e.g. the DVD repodata includes xml that points to where the packages are) Clearly I'm hosting them over HTTP, not from a DVD. Is there an easy way to sort this out? I'm just trying to install CentOS6 on Xen. If there's a turnkey downloadable Xen image with CentOS 6.2 on it, or a downloadable repo image, I'll take that too! Thank you in advance!

• Github Workflow: Pushing small fix branches to remote, or keep them local?

  - by Isaac Hodes

  In Scott Chacon's workflow (explained eg in this SO answer), with essentially two silos (development, and master), if, say I have a small bug to fix (e.g. can be fixed with a few characters) is the optimal way of doing that: a) branch off of development a branch called e.g. fix_123. Push this branch to origin as I work on it. When it's done, code-reviewed, whatever, merge into development and push development to origin. b) Same as above, but without pushing fix_123 to origin.
