• smtpd_helo_restrictions = ..., reject_unknown_helo_hostname occasionally rejects mail I care about, how to handle?

  - by lkraav

  I have configured my postfix as follows: smtpd_helo_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unknown_helo_hostname This is working well because most spambots don't seem to have correct reverse lookups. But every once in a while I run into mail I care about getting reject, because the mail source server admin doesn't care about configuring his server correctly. For example here the server introduces itself as "srv1.xbmc.org" which has no DNS record and fails my basic check. Jan 6 04:42:36 mail postfix/smtpd[660]: connect from xbmc.org[205.251.128.242] Jan 6 04:42:37 mail postfix/smtpd[660]: NOQUEUE: reject: RCPT from xbmc.org[205.251.128.242]: 450 4.7.1 <srv1.xbmc.org>: Helo command rejected: Host not found; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<srv1.xbmc.org> I have tried to contact the server admin several times, but there is no response. What is the optimal way to handle this from my side? Is adding these "special" hosts to mynetworks = my only option? Is perhaps my whole smtpd_helo_restrictions setup wrong in some significant way?

• PTR record not valid for all domains

  - by charnley

  We have an issue sending emails to certain domains, namely Time Warner and Cox. Last week, we decommissioned our Exchange 2003 server and now our Exchange 2010 server is doing all of the transport for our domain. We run our own authoritative name servers, so we are in charge of the DNS and have modified our PTR record to reflect the new server. All mailflow is working except for these 2 domains. When I telnet on port 25 to the mail servers for Cox and Time Warner I am receiving errors. For Cox the error is: 554... rejected - no rDNS And when I telnet to port 25 to the Time Warner mail server we get this: 554 5.7.1 - Connection refused. IP name lookup failed for x.x.x.x I have run through the outbound SMTP test on Microsoft Remote Connectivity Analyzer and get 100% completely successful results. MXToolbox comes up with all successful tests on SMTP as well, showing correct reverse banner check, and no blacklisting. DNSQueries.com shows a valid reverse DNS entry as well for us. Outbound emails to these 2 domains continue to sit in the queue. Any ideas or advice would be greatly appreciated. Thanks!

• Does a mini PCIe SSD fit into a Acer Aspire One?

  - by Narcolapser

  Question: What, if any, mini PCIe SSDs fit into the mini PCIe slot of the Acer Aspire one AOD250? Info: I have an Aspire One and I've been considering loading it with an SSD. The mini PCIe drives fascinate me and so I want to try that approach. Also they tend to be cheaper and not much slower. (at least not on Read time which matters more for a netbook) But I've heard that some times computers don't support certain mini PCIe cards. And I was wondering if anyone knew about the Aspire One? I tried asking Acer tech support, but they didn't know jack and spent the whole time informing that I would have to support my Ubuntu install on my own, which I was. Anyway. Rant Aside, I'm looking at this drive: http://www.newegg.com/Product/Product.aspx?Item=N82E16820183252 It states it is exclusively for the Eee PC. now does that mean It was designed for the Eee PC but will work in my netbook. or is something going to go wrong? (like right now my concern is it physically not fitting.) Any information would be appreciated. o7

• Triple monitor setting in Linux with USB-HDMI adapter

  - by Oscar Carballal

  I'm trying to set up a triple monitor desktop at my office using Fedora 17, but it seems impossible, let me explain the setting: Laptop ASUS K53SD with 2 graphic cards, Intel and nVidia (Screen controled by Intel card) 24" Full HD monitor connected to the HDMI output (controlled by Intel card) 23" Full HD monitor connected to an USB-HDMI adapter (via framebuffer in /dev/fb2, apparently) VGA output (not used) controlled by nVidia card First of all, the USB-HDMI adapter works perfectly, it gives me a green screen (which means the communication is OK) and I can make it work if I set up a single monitor setting via framebuffer in Xorg. Here I leave the page where I got the instructions: http://plugable.com/2011/12/23/usb-graphics-and-linux Now I'm trying to set up the the two main monitors (laptop and 24") with the intel driver and the 23" with the framebuffer, but the most succesful configuration I get is the two main monitors working and the third disconnected. Do you have any idea what can I do to make this work? Here I leave my xRandr output and my Xorg conf: -> xrandr Screen 0: minimum 320 x 200, current 3286 x 1080, maximum 8192 x 8192 LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 193mm 1366x768 60.0*+ 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA2 disconnected (normal left inverted right x axis y axis) HDMI1 connected 1920x1080+1366+0 (normal left inverted right x axis y axis) 531mm x 299mm 1920x1080 60.0*+ 50.0 25.0 30.0 1680x1050 59.9 1680x945 60.0 1400x1050 74.9 59.9 1600x900 60.0 1280x1024 75.0 60.0 1440x900 75.0 59.9 1280x960 60.0 1366x768 60.0 1360x768 60.0 1280x800 74.9 59.9 1152x864 75.0 1280x768 74.9 60.0 1280x720 50.0 60.0 1440x576 25.0 1024x768 75.1 70.1 60.0 1440x480 30.0 1024x576 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 720x576 50.0 848x480 60.0 720x480 59.9 640x480 72.8 75.0 66.7 60.0 59.9 720x400 70.1 DP1 disconnected (normal left inverted right x axis y axis) 1920x1080_60.00 60.0 The Xorg file: # Xorg configuration file for using a tri-head display Section "ServerLayout" Identifier "Layout0" Screen 0 "HDMI" 0 0 Screen 1 "USB" RightOf "HDMI" Option "Xinerama" "on" EndSection ########### MONITORS ################ Section "Monitor" Identifier "USB1" VendorName "Unknown" ModelName "Acer 24as" Option "DPMS" EndSection Section "Monitor" Identifier "HDMI1" VendorName "Unknown" ModelName "Acer 23SH" Option "DPMS" EndSection ########### DEVICES ################## Section "Device" Identifier "Device 0" Driver "intel" BoardName "GeForce" BusID "PCI:0:02:0" Screen 0 EndSection Section "Device" Identifier "USB Device 0" driver "fbdev" Option "fbdev" "/dev/fb2" Option "ShadowFB" "off" EndSection ############## SCREENS ###################### Section "Screen" Identifier "HDMI" Device "Device 0" Monitor "HDMI1" DefaultDepth 24 SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "USB" Device "USB Device 0" Monitor "USB1" DefaultDepth 24 SubSection "Display" Depth 24 EndSubSection EndSection

• Shrinking a large transaction log on a full drive

  - by Sam

  Someone fired off an update statement as part of some maintenance which did a cross join update on two tables with 200,000 records in each. That's 40 trillion statements, which would explain part of how the log grew to 200GB. I also did not have the log file capped, which is another problem I will be taking care of server wide - where we have almost 200 databases residing. The 'solution' I used was to backup the database, backup the log with truncate_only, and then backup the database again. I then shrunk the log file and set a cap on the log. Seeing as there were other databases using the log drive, I was in a bit of a rush to clean it out. I might have been able to back the log file up to our backup drive, hoping that no other databases needed to grow their log file. Paul Randal from http://technet.microsoft.com/en-us/magazine/2009.02.logging.aspx Under no circumstances should you delete the transaction log, try to rebuild it using undocumented commands, or simply truncate it using the NO_LOG or TRUNCATE_ONLY options of BACKUP LOG (which have been removed in SQL Server 2008). These options will either cause transactional inconsistency (and more than likely corruption) or remove the possibility of being able to properly recover the database. Were there any other options I'm not aware of?

• EFS Remote Encryption

  - by Apoulet

  We have been trying to setup EFS across our domain. Unfortunately Reading/Writing file over network share does not work, we get an "Access Denied" error. Another worrying fact is that I managed to get it working for 1 machine but no other would work. The machines are all Windows 2008R2, running as VM under ESXi host. According to: http://technet.microsoft.com/en-us/library/bb457116.aspx#EHAA We setup the involved machine to be trusted for delegation The user are not restricted and can be trusted for delegation. The users have logged-in on both side and can read/write encrypted files without issues locally. I enabled Kerberos logging in the registry and this is the relevant logs that I get on the machine that has the encrypted files.

• Upgrading MySQL Connector/Net

  - by Todd Grover

  I am trying to publish a website with our hosting provider. I am getting error due to the fact that they only allow a medium trust and the MySQL Connector/Net that I am using requires reflection to work. Unfortunately, reflection is not allowed in a medium trust. After some research I found out that the newest version of the MySQL Connector/Net may solve this problem. Connector/Net 6.6 includes enhancements to partial trust support to allow hosting services to deploy applications without installing the Connector/Net library in the GAC. I am thinking that will solve my problem. So, I unistalled MySQL Connector/Net 6.4.4 and I installed MySQL Connector/Net 6.6.4. When I run the application in Visual Studio 2010 I get the error: ProviderIncompatibleException was unhandled by user code The message is An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct. InnerException is The provider did not return a ProviderManifestToken string. Everything works fine when I have Connector/Net 6.4.4 installed. I can access the database and perform Read/Write/Delete action against it. I have a reference to the following in the project: MySql.Data MySql.Data.Entity MySql.Web My connection string in Web.config <connectionStrings> <add name="AESSmartEntities" connectionString="server=ec2-xxx-xx-xxx-xx.compute-1.amazonaws.com; user=root; database=nunya; port=3306; password=xxxxxxx;" providerName="MySql.Data.MySqlClient" /> </connectionStrings> What might I be doing wrong? Do I need any additional setting(s) to work with version 6.6.4 that wasn't required in the older version 6.4.4?

• How to make Synaptics touchpad work better on Linux?

  - by whitequark

  I have Debian Squeeze currently installed on a Samsung N250 netbook with a Synaptics touchpad. These touchpads are, generally, good, and everything works perfectly on Windows. The support is extremely sucky on Linux through. Of course it has all the cool features like two-finger scrolling, but the cursor (or whatever is a replacement for cursor when scrolling) is trembling awfully. It trembles when I just keep the finger on touchpad, it shakes awfully if the finger is close to the top of touchpad, and when I'm scrolling with it (no matter with two fingers or one), the page shakes a lot too. None of this behavior is observed even in Windows XP with just the default drivers installed. Here's the Xorg version: $ Xorg -version X.Org X Server 1.7.7 Release Date: 2010-05-04 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.32-5-686 i686 Debian Current Operating System: Linux mannaz 2.6.32-5-686 #1 SMP Fri Dec 10 16:12:40 UTC 2010 i686 Kernel command line: BOOT_IMAGE=/vmlinuz-2.6.32-5-686 root=/dev/mapper/mannaz-root ro quiet splash Build Date: 02 December 2010 01:08:37AM xorg-server 2:1.7.7-10 (Julien Cristau <[email protected]>) Current version of pixman: 0.16.4 and here is synclient -l output: http://pastebin.com/Eqa6hGXP

• SSL timeout on some sites, across all browsers, on Mac OS X Snow Leopard

  - by dansays

  For the past several weeks, I've been receiving "Error 7 (net::ERR_TIMED_OUT): The operation timed out" when I attempt to connect to either Twitter or Paypal via SSL. I get this specific error in Google Chrome, but the same problem occurs in both Safari and Firefox. Other sites work fine, and other computers on my network can access these two sites. I have no firewall settings that would prevent me from accessing these sites over port 443. I notice that both Twitter and Paypal both have "Verisign Class 3 Extended Validation SSL CA" certificates. It is unclear whether this is related to the problem. In an effort to troubleshoot, I attempted to open the test sites referenced on Verisign's root certificate support page, which worked fine. Just to be sure, I downloaded and installed the root package file and installed all included Verisign certificates. No joy. I feel like I've hit a dead end. Any ideas? Update the first: I also cannot connect to FedEx.com, who also has a Verisign Class 3 Extended Validation cert. Update the second: Aaaaaaand it fixed itself. I did nothing. Or, I did something that worked, but in a delayed fashion. Frustrating, but a win is a win. I'll take it.

• Celery daemon as a Ubuntu service does not consume tasks while running from terminal does

  - by Guy

  On Ubuntu 11.10, I have to issue python tasks from django using celery. I'm currently testing on the same machine but eventually the celery worker should run on a remote machine. django uses the following settings: BROKER_HOST = "127.0.0.1" BROKER_PORT = 5672 BROKER_VHOST = "/my_vhost" BROKER_USER = "celery" BROKER_PASSWORD = "celery" I can also see my task queued in http://localhost:55672/#/queues the celery daemon uses the following configuration (celeryconfig.py): BROKER_HOST = "127.0.0.1" BROKER_PORT = 5672 BROKER_USER = "celery" BROKER_PASSWORD = "celery" BROKER_VHOST = "/my_vhost" CELERY_RESULT_BACKEND = "amqp" import os import sys sys.path.append(os.getcwd()) CELERY_IMPORTS = ("tasks", ) running celeryd -l info works well and now I want to run it as a service. I've followed the instructions from http://ask.github.com/celery/cookbook/daemonizing.html and now I'm trying to run it using: sudo /etc/init.d/celeryd start But the message is not being consumed, no error in the celery log either. /etc/default/celeryd CELERYD_NODES="w1" CELERYD_CHDIR="/path/to/django/project" CELERYD_OPTS="--time-limit=300 --concurrency=1" CELERY_CONFIG_MODULE="celeryconfig" # %n will be replaced with the nodename.

CELERYD_USER="celery" CELERYD_GROUP="celery" I've also created user celery in Ubuntu not sure if its necessary. Any help will be appreciated, Thanks, Guy

• Why is Apache htdigest authentication failing in IE10 on Windows 8?

  - by Kevin Fodness

  One of our developers reported that for the past week or two, the htdigest authentication that we have set up on our test sites in Apache is not working in IE10 on Windows 8. It's fine on IE10 on Windows 7, and it's fine on Chrome on Windows 8. The specific behavior is: Navigate to site with htdigest authentication enabled, username and password form pops up, enter correct username and password, and the username and password box pops up again. Potentially useful information: All patches applied on Windows 8 box No additional software on Windows 8 box other than Outlook 2013 and a browser test suite (Chrome, Firefox, Opera, Chrome Canary, Opera Next) Win8 running in a virtual machine on Xen Same behavior can be replicated on Win8/IE10 on Browserstack.com Server running Ubuntu 10.10 with Apache 2.2.16 This feels like a patch was applied to the Windows box that broke digest authentication for IE10 on Win8 (box configured for automatic updates). However, without knowing a specific date I can't necessarily nail this down. Has anyone else experienced this problem? EDIT: This problem only happens in the "Metro" interface, not when running IE10 in desktop mode. As of a few weeks ago, it worked fine even in the "Metro" interface.

• Error related to pkg-config when installing frei0r as part of another package

  - by Anentropic

  I am trying to build https://github.com/mltframework/shotcut on OS X Lion (using their script in scripts/build_shotcut.sh) and after numerous hurdles I'm stuck on this error: ./configure: line 16062: syntax error near unexpected token `OPENCV,' ./configure: line 16062: `PKG_CHECK_MODULES(OPENCV, opencv >= 1.0.0, HAVE_OPENCV=true, true)' ERROR: Unable to configure frei0r From what I already googled this means that the PKG_CHECK_MODULES macro hasn't been defined, which probably means there's something wrong with my pkg-config, which I installed via Homebrew. Sounds like the pkg.m4 file isn't found. When I brew install pkg-config I get the following warning: Warning: m4 macros were installed to "share/aclocal". Homebrew does not append "/usr/local/share/aclocal" to "/usr/share/aclocal/dirlist". If an autoconf script you use requires these m4 macros, you'll need to add this path manually. Well I've appended that line to the dirlist file and it doesn't fix the problem above. Can anyone suggest a way forward here? I have briefly tried building my own pkg-config from source but (bizarrely) when I tried to ./configure I got the following error: checking for pkg-config... no ./configure: line 13540: --exists: command not found configure: error: pkg-config and glib-2.0 not found, please set GLIB_CFLAGS and GLIB_LIBS to the correct values if building pkg-config needs pkg-config it seems like a weird catch 22 situation... I think this is probably an unnecessary sidetrack anyway.

• Process to replace motherboard and keep CPU

  - by jolivier

  My motherboard has been diagnosed with the Sandy Bridge issue (http://vip.asus.com/eservice/changeSandybridge_MB.aspx?slanguage=en-us) so I am asked by my reseller to send back my motherboard to have a new one compatible with the previous one. My problem is that I have a not cheap Intel CPU currently on it, with its standard heatsink/fan. I would obviously like to keep it to plug it on the new motherboard. I am quite woried about the thermal paste. I was planning to: Remove the CPU and the HSF together (I think they are sticked to each other). Try to separate the CPU and the HSF (I'm not sure how) Clean both of the surfaces When the new motherboard is here, put the CPU back on it. Have new thermal paste to put again on the CPU, put it on the CPU Add the HSF again Do you see any problem about this process? Recommendations? Is it possible to keep the CPU and the HSF together for the whole process or is it impossible to plug the CPU back on the new motherboard in this case? Thanks in advance for your answers. Olivier

• Blink build with Xcode failed

  I found a GPL-ed SIP client for Mac, Blink. I'd like to build it from source since the binaries are only available as paid download. Just FYI i'm studying programming at university but have no experience in building complex application from source. After downloading the content of the repository i opened the Xcode project and tried to build on OS X 10.7, Xcode 4.2.1. Unfortunately the build fail with 1 error and many warnings Most of the warnings are like this: Attribute Unavailable: Custom Identifiers in Interface Builder versions prior to 3.2 The error message is: Apple Mach-O Linker (ld) Error Command /Developer/usr/bin/clang failed with exit code 1 preceded by the warning Apple Mach-O Linker (ld) Warning directory not found for option '-L/Users/Sergio/Downloads/Blink/devel.ag-projects.com/repositories/public/blink-cocoa/Distribution/Frameworks' I notice that in the list of required files i have this files missing: Dependencies/Frameworks libgcrypt.11.6.0.dylib libgcrypt.11.dylib libgnutls-extra.26.dylib libgnutls.26.dylib libgpg-error.0.dylib libintl.8.dylib liblzo.1.dylib libtasn1.3.dylib Dependencies/Resources lib Frameworks/Linked Frameworks Sparkle.framework Products Blink.app It should be possible to download these files somewhere.

• Adobe e-book reader ("Digital Editions") not downloading on Mac OS X

  - by doug

  i recently bought a couple of books from ebooks.com, which i thought would be ordinary pdf files. After paying for them, and downloading them, you learn that while they are pdf files, they come with a lot of DRM baggage. The most conspicuous is that you can only view these files using an Adobe ebook reader called Adobe Digital Editions. (Note: this is not the ordinary Adobe Acrobat Reader, or anything close--it's a dedicated app for reading DRM-laden files. Fine--i'll know better next time. Still, i paid for these books and there's only one way i can actually read them, which happens to be an App that i seem to be unable to download. Here's the error message i get: "Couldn't write the application to the hard disk. Please verify the hard disk is available and try again" I've tried on several different browsers. My rig is a MBP, OS X 10.6.2. I've also checked the Adobe boards and this doesn't appear to be a known issue, nor could i find anything on their discussion forums. And just to be sure, i've checked my hard disk--no problems, plenty of space, and i have no problem, nor have i ever downloading other apps.

• Where is the bare cygwin package list located and how do I manipulate it?

  - by matnagel

  Where is the bare cygwin package list located and how do I manipulate it programmatically or from a shell or with a different method than the gui? I know the gui (setup.exe), and I'd love to go one or more levels deeper. I can retrieve a list of selected/installed packages ( http://serverfault.com/questions/83456/cygwin-package-management ), but how do I write it back or to a different machine? What I have in mind is when I install a new windows I would like to start with my package list in text form, an apply or inject it somehow to the new system. Where is it? In the registry? In a binary file? in a local database? Or has anybody done this, is there a tool, a tutorial? The essence of what I want is to manipulate the selected package list with something else than the gui. It is ok for me to use the gui for the setup process. So I could imagein manipulating the package List and then run setup.exe and just click through it. Note: I do not want to manipulate the list of already installed packages but of packages that "should be installed". But if htis is not possible, maybe there is some workaround. E.g add an outdated version as installed and the installer will then install the new version.

• Need to have access to my office PC from my laptop hopping through two VPN servers

  - by Andriy Yurchuk

  Here's the illustration of what I have ( http://clip2net.com/s/2fvar ): My office PC with it's IP of 123.45.e.f. Office VPN, which I will connect to from my VPS to get to my office PC. My own VPS, which I use as a: client to connect to office VPN (through vpnc, which creates a tun0 with 123.45.c.d IP address); VPN server my laptop can connect to (OpenVPN, tun1, 10.8.0.1) My own laptop I will use as a VPN client to connect to VPS OpenVPN server (will create a tun0 with 10.8.0.2 IP address) Now what I have to do is to allow my laptop to connect to at least my office PC, but preferably to all the 123.45.x.x subnet. Please advice on how to best configure OpenVPN, routing, iptables or whatever else is needed on my VPS so that my laptop could gain access to my office PC. P.S. The reason I'm hopping through my VPS is that being connected to the office WiFi I cannot access my office PC and I cannot connect to office VPN (which is another way to access my office PC). The only way to access my PC from office WiFi I have is hopping though an outside network.

• OS X borked; need to backup outside of Time Machine

  - by rlbgator

  Quick Background: iMac G5 (the white one; 4 years old?) Running Leopard 10.5.something. Time Machine started failing on me; and every time I touch the Finder, things beachball like crazy. Booting from install disk then using Disk Utility to "Repair Disk" also fails. I'm left with the conclusion that I have a corrupt file somewhere important, that's (i) keeping TM from working and (ii) messing with basic functionality. I am not (yet) savvy enough in OS X to know what logs to look in, or how to decipher them - but 'corrupt file' seems to be the likely case, based on my readings of apple.com forum threads. So I think I need to backup, outside of Time Machine, then install fresh OS X on a new drive (or maybe SpinRite the current drive?). I'm able to put a (non-Time Machine) external USB drive on, so I dragged all 3 Users' folders to that... am I done backing up? Am I going to have a massive Permissions problem, trying to put things back together after a re-install? Thanks for reading.

• Can't seem to stop Postfix backscatter

  - by Ian

  I've just migrated to a Postfix system and can't seem to stop the backscatter messages to unknown addresses on the site. I have a file, validrcpt, that lists all the valid emails on the site - about eight of them. Yet when a message is sent to a non-existent address, instead of just dropping it, postfix is replying with a "Recipient address rejected: User unknown in virtual mailbox table" email. Do I have something set wrong?

• How to remove Character Style in Word 2003

  - by joe

  I am copying text into a Word document that has its styles protected. Some of the text has a Character style applied to it that I would like to remove. I can change the style and it looks okay visually, but when you click inside the text itself you can see in the style menu that the Character style is still applied. I try to change the style using the style drop down but the Character style won't go away even if I change it to the Paragraph style. Does anyone know what I am talking about and/or have any techniques for removing Character styles? I am looking forward to your responses. Let me know if I need to clarify. Thanks! UPDATE: My issue is that the Paragraph style is changing correctly, but the Character style remains applied even though the text is displayed as if the style is not applied. See http://office.microsoft.com/en-us/word/HA011876141033.aspx if you are not sure what I meen by Character styles. There are four types of styles — paragraph, character, list, and table (list and table styles are new as of Word 2002). However, the majority of styles you'll use are paragraph styles.

• Which events specifically cause Windows 2008 to mark a SAN volume offline?

  - by Jeremy

  I am searching for specific criteria/events that will cause Windows 2008 to mark a SAN volume as offline in disk management, even though it is connected to that SAN volume via FC or iSCSI. Microsoft states that "A dynamic disk may become Offline if it is corrupted or intermittently unavailable. A dynamic disk may also become Offline if you attempt to import a foreign (dynamic) disk and the import fails. An error icon appears on the Offline disk. Only dynamic disks display the Missing or Offline status." I am specifically wondering if, on the SAN, changing the path to the disk (such as the disk being presented to the host via a different iSCSI target IQN or a different LUN #) would cause a volume to be offlined in disk management. Thanks! Edit: I have already found two reasons why a disk might be set offline, disk signature collisions and the SAN disk policy. Bounty would be awarded to someone who can find further documented reasons related to changes in the volume's path. Disk signature collisions: http://blogs.technet.com/b/markrussinovich/archive/2011/11/08/3463572.aspx SAN disk policy: http://jeffwouters.nl/index.php/2011/06/disk-offline-with-error-the-disk-is-offline-because-of-a-policy-set-by-an-administrator/

• Apache Proxy and Rewrite, append directory to URL

  - by ionFish

  I have a backend server running on http://10.0.2.20/ from the local network, which serves similar to this: / (root) | |_user1/ | |_www/ | |_private/ | |_user2/ |_www/ |_private/ (etc.) Accessing http://10.0.2.20/user1/ of course, contains 'www' and 'private' folders and is proxied through a public server using Apache's Reverse Proxy. I'd like it so the following happens: http://public-proxy-server/user1/ actually shows the content from http://10.0.2.20/user1/www/ without indicating it in the URL. (/private/ would not be accessible via the public proxy server). The key here, is for it to be dynamic, so all requests to http://public-proxy-server/*/should show content from http://10.0.2.20/*/www/. Again, the proxy currently works fine; below is the config: (On the public server) <VirtualHost *:80> ServerName www.domain.com ProxyRequests Off ProxyPreserveHost On ProxyVia full ProxyPass / http://10.0.2.20/ ProxyPassReverse / http://10.0.2.20/ </VirtualHost> (On the backend server) <VirtualHost *:80> ... #this directory contains folders 'user1' and 'user2' DocumentRoot /var/www/ ... </VirtualHost>

• Enrich a dataset of POIs with OpenStreetMap

  - by zero

  update: due to some hints of users - eg oliver Salzburg and slhck i have been aware of gis.stackexchange.com - so i moved the topic on my own: Plz can you or somebody who has the permission close the article - since we do not need this topic on two sites. Thx for your work. KEEP up the service here! STACK-sites rock. I have a list of POIs, some with a full description and some with only a few data entries, like the following: 6.9441000 50.9242000 [50677] (Ital) Casa di Biase [Köln] 6.9373600 50.9291800 [50674] (Ital) Al Setaccio [Köln] However, I need the full dataset. Can I get this somewhere? If I have all the position data, is it possible to find the rest? a. name of the street b. name of the town So for example, the data should finally look like this: 10.5346100 52.1613600 [38300] (Chin) Wanbao Kommissstr.9 [Wolfenbüttel] 13.2832500 52.4422600 [14167] (Ital) LaPergola Unter den Eichen 84d [Berlin] 13.3177700 52.5062900 [10625] (Chin) Good Friends Kantstr.30 [Berlin] Can I do this with OpenStreetMap? Should I parse OpenStreetMap data? Or OpenBabel?

• setting up phpmyadmin with nginx within ubuntu 11.04

  - by Patrick

  I have nginx and php5-fpm running on ubuntu 11.04. I have installed phpmyadmin but im having trouble accessing it. I would like to access it via http://localhost/phpmyadmin I've used all the default locations for the nginx, php5, and phpmyadmin installs. I'm being directed to use the block below by the blog guide im following, but im not sure what to change to get it to point how im wanting it to. server { listen 80; server_name php.example.com; // <-I know i need to edit this, but not sure to what. access_log /var/log/nginx/localhost.access.log; root /usr/share/phpmyadmin; index index.php; location / { try_files $uri $uri/ @phpmyadmin; } location @phpmyadmin { fastcgi_pass 127.0.0.1:9000; fastcgi_param SCRIPT_FILENAME /usr/share/phpmyadmin/index.php; include /etc/nginx/fastcgi_params; fastcgi_param SCRIPT_NAME /index.php; } # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /usr/share/phpmyadmin$fastcgi_script_name; include fastcgi_params; } }

• What are the steps needed to set up and use security for AWS command line tools?

  - by chris

  I've been trying to set up the AWS command-line tools following Eric's most useful guide at http://alestic.com/2012/09/aws-command-line-tools. I can't seem to find a good how-to for how to generate the x509 certificate and private key, and how that relates to the various security files the guide creates. Update: I have found a couple of links that describe the some steps. These steps seem to work, however I'm not sure if this is secure & the best way to do it: 1) Create a private key openssl genrsa -out my-private-key.pem 2048 2) Create x.509 cert openssl req -new -x509 -key my-private-key.pem -out my-x509-cert.pem -days 365 Hit enter to accept all of the defaults. Then, from the IAM Dashboard, User, select a user & click on the "Security Credentials" tab. Click on "Manage Signing Certificates", then "Upload Signing Certificate", paste in the contents of my-x509-cert.pem, click OK and it should be accepted. One step that is discussed, but not required for me, was the addition and subsequent removal of a pass phrase on the private key. Should I have been prompted for one, and is my cert potentially unsafe because of this?
