• bind9 named.conf zones size limit

  - by mox601

  I am trying to set up a test environment on my local machine, and I am trying to start a DNS daemon that loads tha configuration from a named.conf.custom file. As long as the size of that file is like 3-4 zones, the bind9 daemon loads fine, but when i enter the config file i need (like 10000 lines long), bind can't startup and in the syslog i find this message: starting BIND 9.7.0-P1 -u bind Jun 14 17:06:06 cibionte-pc named[9785]: built with '--prefix=/usr' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--sysconfdir=/etc/bind' '--localstatedir=/var' '--enable-threads' '--enable-largefile' '--with-libtool' '--enable-shared' '--enable-static' '--with-openssl=/usr' '--with-gssapi=/usr' '--with-gnu-ld' '--with-dlz-postgres=no' '--with-dlz-mysql=no' '--with-dlz-bdb=yes' '--with-dlz-filesystem=yes' '--with-dlz-ldap=yes' '--with-dlz-stub=yes' '--with-geoip=/usr' '--enable-ipv6' 'CFLAGS=-fno-strict-aliasing -DDIG_SIGCHASE -O2' 'LDFLAGS=-Wl,-Bsymbolic-functions' 'CPPFLAGS=' Jun 14 17:06:06 cibionte-pc named[9785]: adjusted limit on open files from 1024 to 1048576 Jun 14 17:06:06 cibionte-pc named[9785]: found 1 CPU, using 1 worker thread Jun 14 17:06:06 cibionte-pc named[9785]: using up to 4096 sockets Jun 14 17:06:06 cibionte-pc named[9785]: loading configuration from '/etc/bind/named.conf' Jun 14 17:06:06 cibionte-pc named[9785]: /etc/bind/named.conf.saferinternet:1: unknown option 'zone' Jun 14 17:06:06 cibionte-pc named[9785]: loading configuration: failure Jun 14 17:06:06 cibionte-pc named[9785]: exiting (due to fatal error) Are there any limits on the file size bind9 is allowed to load?

• Enabling mod_wsgi in Apache for a Django app on Gentoo

  - by hobbes3

  I installed Apache, Django, and mod_wsgi on Gentoo using emerge (on Amazon EC2). I know that the mod_wsgi is configured in /etc/apache2/modules.d/70_mod_wsgi.conf: <IfDefine WSGI> LoadModule wsgi_module modules/mod_wsgi.so </IfDefine> # vim: ts=4 filetype=apache So in my /etc/conf.d/apache I added the WSGI module: APACHE2_OPTS="-D DEFAULT_VHOST -D INFO -D SSL -D SSL_DEFAULT_VHOST -D LANGUAGE -D WSGI" But when I try to list the loaded module, mod_wsgi isn't listed. root ~ # apache2 -M | grep wsgi Syntax OK I also know that mod_wsgi isn't loading properly because the Apache configuration file doesn't recognize WSGIScriptAlias. By the way for Django to work I need to include a custom Apache configuration file. Where should I insert the line below? Include "/var/www/localhost/htdocs/mysite/apache/apache_django_wsgi.conf" I currently have that in the httpd.conf file but I feel like that file will get reseted whenever I upgrade Gentoo or related package. EDIT: it seems the mod_wsgi file is located in /usr/lib64/apache2/modules/mod_wsgi.so. Here is my detailed Apache settings: root@ip-99-99-99-99 /usr/portage/eclass # apache2 -V Server version: Apache/2.2.21 (Unix) Server built: Mar 7 2012 06:52:30 Server's Module Magic Number: 20051115:30 Server loaded: APR 1.4.5, APR-Util 1.3.12 Compiled using: APR 1.4.5, APR-Util 1.3.12 Architecture: 64-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/usr" -D SUEXEC_BIN="/usr/sbin/suexec" -D DEFAULT_PIDLOG="/var/run/httpd.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="/var/run/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="/etc/apache2/mime.types" -D SERVER_CONFIG_FILE="/etc/apache2/httpd.conf"

• Using virtualization infrastructure for J2EE application distribution- viable alternative?

  - by Dan

  Our company builds custom J2EE web solutions. At the moment, we use standard J2EE distribution mechanisms (ear/war archives). Application servers are generally administered by our clients' IT departments and since we do not have complete control over the environment, a lot of entropy can be introduced into the solution. For example: latest app. server patch not applied conflicting third party libraries inside the app. server root server runtime and tuning parameters not configured (for example, number of connections in database pool) We are looking into using virtualization infrastructure for J2EE application distribution. Instead of sending the ear/war archive, we’d send image with application server node and our application preinstalled. Some of the benefits are same as using with using virtualization infrastructure in general, namely better use of hardware resources. For us, it reduces the entropy of hosting infrastructure - distributing VM should be less affected by hosting environment. So far, the downside I see can be in application server licenses, here they will have to use dedicated servers for our solution, but this is generally already done that way. Also, there is a complexity with maintaining virtualization infrastructure, but this is often something IT departments have more experience with than with administering and fine-tuning J2EE solutions. Anyone has experience with this model? What are the downsides? Will we not just replace one type of complexity with other?

• Best way to integrate applications to windows 7 install.wim image

  - by cyph3r

  I have right now an unmodified .iso of a windows 7 32bit and 64bit installation disk. And I need to integrate to that some applications (office, adobe reader etc) and windows updates so that when windows are installed the above applications/updates are already installed and working. Requirements: My output has to be a install.wim image containing the new/improved windows installation files because the deployment is done via a pxe server and a custom windowsPE enviroment. The procedure to create the install.wim has to be as automatic as possible. I can't create it manually every time I want to incorporate a new windows or application update to the image. The image will be installed on 100+ computers so it needs to be 'generic'. I've never done something like this before but from what I searched a possible solution to this issue would be: To create a reference installation (preferably on a vm so I can take snapshots) complete with its applications/updates/settings. After the complete setup I take a snapshot of the installation Run C:\Windows\System32\sysprep\sysprep.exe /oobe /generalize /shutdown to sysprep the machine. Boot to a WindowsPE enviroment and capture the .wim image using gimagex. Deploy the .wim and enjoy the rapid installation times. :D Does that sound ok? Would you recommend anything else? Right now the applications are installed after the installation of windows is complete. So the total installation time is quite long. That's why I need a different approach.

• Puppet - Is it possible to use a global var to pull in a template with the same name?

  - by Mike Purcell

  I'm new to puppet. As such I am trying to work my way around the best way to setup my manifests that make sense. Following the DRY (don't repeat yourself) principle, I am trying to load common directives in one template, then load in environment specific directives from a file matching the environment. Basically like this: # nodes.pp node base_dev { $service_env = 'dev' } node 'service1.ownij.lan' inherits base_dev { include global_env_specific } class global_env_specific { include shell::bash } # modules/shell/bash.pp class shell::bash inherits shell { notify{"Service env: ${service_env}": } file { '/etc/profile.d/custom_test.sh': content => template('_global/prefix.erb', 'shell/bash/global.erb', 'shell/bash/$service_env.erb'), mode => 644 } } But every time I run puppet agent --test puppet complains that it can't find the shell/bash/$service_env.erb file, but I double checked that it exists. I know the var is accessible due to the notify statement outputting the expected value, so I suspect I am doing which is not allowed. I know I could have a single template.erb and pass variables to the template, which would work in this case because the custom.sh file is small and not many changes across environments, but for more complex configs (httpd, solr, etc) I'd prefer to access environment specific files. I am also aware that I can specify environment specific module paths, but I'd prefer to just handle this behavior at the template level, instead of having several, closely named directories. Thanks.

• Conditionally Rewrite Email Headers (From & Reply-To) Exchange 2010

  - by NorthVandea

  I have a client who maintains Company A (with email addresses %username%@companyA.com) and they own the domain companyB.com however there is no "infrastructure" (no Exchange server) set up specifically for companyB.com. My client needs to be able to have the end users within it's company (companyA.com) add a specific word or phrase to the Subject (or Body) line of the Outgoing email (they are only concerned with outgoing, incoming is a non-issue in this case) that triggers the Exchange 2010 servers to rewrite the header From and Reply-To [email protected] with [email protected] but this re-write should ONLY occur if the user places the key word/phrase in the Subject (or Body). I have attempted using Transport Rules and the New-AddressRewriteEntry cmdlet however each seems to have a limitation. From what I can tell Transport Rules cannot re-write the From/Reply-To fields and New-AddressRewriteEntry cannot be conditionally triggered based on message content. So to recap: User sends email outside the organization: From and Reply-To remain [email protected] User sends email outside the organization WITH "KeyWord" in the Subject or Body: From and Reply-To change to [email protected] automatically. Anyone know how this could be done WITHOUT coding a new Mail Agent? I don't have the programming knowledge to code a custom Agent... I can use any function of Exchange Management Shell or Console. Alternatively if anyone knows of a simple add-on program that could do this that would be good too. Any help would be greatly appreciated! Thank you!!!

• Affordable combined Ruby/Rails/Redmine + Subversion hosting?

  - by Pekka

  I'm a self employed web developer and after nine years of hard work, I'm looking to become a bit more "vagrant" starting next year, do some much-needed traveling and a bit and work off and on, making use of one of the greatest advantages of a programming job: The ability to work virtually from everywhere. For that, I am looking for a reliable hosting company I can entrust my code to in the form of a number of Subversion repositories, and an installation of the Redmine project management tool. As my financial situation may vary during traveling, I am looking for something I can pay up front for a year or two, and is obviously not too pricey. I don't care where the company is located, as long as it's trustworthy and solid, meaning it's not likely to go out of business next month. Does anybody know good recommendations? Preferably from own, personal, good experience. I have looked at CVSDude / Codesion and while they are certainly great, they don't offer Redmine of course, and seem to be aiming toward bigger organizations mainly. What I would need: 2-5 Gigs of space minimum, freely distributable between SVN, and Redmine attachments Unlimited number of Subversion projects Access control (team members / checkout-only accounts / etc.) I don't mind configuring the svn settings on file basis myself I need the possibility to map a custom domain to the package that is hosted elsewhere Frequent backups and access to those backups through FTP or other means I have been running my own virtual server for this until now, but I don't want the hassle, especially on the security side, while I may not always have the internet connection to fix problems that may come up.

• Unattended Kickstart Install

  - by Eric

  I've looked around quite a bit and have seen similar setup and questions, but none seem to work for me. I'm using the following command to create a custom ISO: /usr/bin/livecd-creator --config=/usr/share/livecd-tools/test.ks --fslabel=TestAppliance --cache=/var/cache/live This works great and it creates the ISO with all of the packages and configs I want on it. My issue is that I want the install to be unattended. However, every time I start the CD, it asks for all of the info such as keyboard, time zone, root password, etc. These are my basic settings I have in my kickstart script prior to the packages section. cdrom install autopart autostep xconfig --startxonboot rootpw testpassword lang en_US.UTF-8 keyboard us timezone --utc America/New_York auth --useshadow --enablemd5 selinux --disabled services --enabled=iptables,rsyslog,sshd,ntpd,NetworkManager,network --disabled=sendmail,cups,firstboot,ip6tables clearpart --all So after looking around, I was told that I need to modify my isolinux.cfg file to either do "ks=http://X.X.X.X/location/to/test.ks" or "ks=cdrom:/test.ks". I've tried both methods and it still forces me to go through the install process. When I tail the apache logs on the server, I see that the ISO never even tries to get the file. Below are the exact syntax I'm trying on my isolinux.cfg file. label http menu label HTTP kernel vmlinuz0 append initrd=initrd0.img ks=http://192.168.56.101/files/test.ks ksdevice=eth0 label localks menu label LocalKS kernel vmlinuz0 append initrd=initrd0.img ks=cdrom:/test.ks label install0 menu label Install kernel vmlinuz0 append initrd=initrd0.img root=live:CDLABEL=PerimeterAppliance rootfstype=auto ro liveimg liveinst noswap rd_NO_LUKS rd_NO_MD rd_NO_DM menu default EOF_boot_menu The first 2 give me a "dracut: fatal: no or empty root=" error until I give it a root= option and then it just skips the kickstart completely. The last one is my default option that works fine, but just requires a lot of user input. Any help would be greatly appreciated.

• Outlook conversation view and categories

  - by Greg Jackson

  At work, I tend to receive a couple of hundred emails a day. To keep from being overwhelmed, I have been using categories to sort and prioritize my mail messages. I auto-assign categories, then group by them: Code Reviews, To, CC, Distribution List/BCC. This means that, for example, a message that's explicitly to me will always show up higher in my inbox than one I get because I'm on a Distribution List. It's a huge time saver and it brings important emails to my attention much more quickly. Recently, the email threads I'm involved in have started to get quite long, and I'd like to be able to use conversation view, or at least sort by subject. Outlook, however, doesn't seem to support any (useful) combination of conversation view and categories. I've tried the following things without success: Grouping by category, then conversation view -- Outlook gives me an error (the grouping/sort combination is too complex). Using a custom view to group by conversation -- category doesn't show up as an option to sort by Grouping by category, then subject -- Getting closer, but the top subject is the first alphabetically, not the most recent Grouping by conversation, then category -- This works, but it doesn't do me much good, because the top conversation is the latest, without regard to what category it belongs to Is there a way for me to retain my category system or something similar while taking advantage of grouping related emails together? I've written Outlook plugins in the past, so even that's not too out there to serve as a proper solution.

• Can I get all active directory passwords in clear text using reversible encryption?

  - by christian123

  EDIT: Can anybody actually answer the question? Thanks, I don't need no audit trail, I WILL know all the passwords and users can't change them and I will continue to do so. This is not for hacking! We recently migrated away from a old and rusty Linux/Samba domain to an active directory. We had a custom little interface to manage accounts there. It always stored the passwords of all users and all service accounts in cleartext in a secure location (Of course, many of you will certainly not think of this a being secure, but without real exploits nobody could read that) and disabled password changing on the samba domain controller. In addition, no user can ever select his own passwords, we create them using pwgen. We don't change them every 40 days or so, but only every 2 years to reward employees for really learning them and NOT writing them down. We need the passwords to e.g. go into user accounts and modify settings that are too complicated for group policies or to help users. These might certainly be controversial policies, but I want to continue them on AD. Now I save new accounts and their PWGEN-generated (pwgen creates nice sounding random words with nice amounts of vowels, consonants and numbers) manually into the old text-file that the old scripts used to maintain automatically. How can I get this functionality back in AD? I see that there is "reversible encryption" in AD accounts, probably for challenge response authentication systems that need the cleartext password stored on the server. Is there a script that displays all these passwords? That would be great. (Again: I trust my DC not to be compromised.) Or can I have a plugin into AD users&computers that gets a notification of every new password and stores it into a file? On clients that is possible with GINA-dlls, they can get notified about passwords and get the cleartext.

• Server freezes while installing Redhat Enterprise Linux Server 6

  - by eisaacson

  We've tried both the first options Install or upgrade an existing system Install system with basic video driver When trying option #1, it gets to a screen that has a solid cursor about halfway down, then freezes. When trying option #2, it freezes at the point where it says: Waiting for hardware to initialize... Of course, we bought the unsupported version and haven't found anything to help us so far. Here are the specs to the server in the original post: ASUS P8Z68-M Pro LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard with UEFI BIOS RAIDMAX Reiter ATX-305WBP Black Steel / Plastic ATX Mid Tower Computer Case 450W Power Supply Intel Core i7-2600 Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 2000 BX80623I72600 16GB Ram OCZ Agility 3 SSD 120GB From some of the posts out there could the UEFI Bios or the Sandy Bridge processor be a culprit here? We just tried the DVD on a different computer and it got past that point with ease. It's a standard Dell build compared to our custom machine. Could it be having difficulty recognizing drivers? How do we get past that?

• How to figure out what VirtualBox did?

  - by AndrejaKo

  I'm trying to boot a custom made-in-ASM OS on my recent laptop. The OS is intended to be installed on a floppy and during make creates a bootable floppy. Since I don't have a floppy drive, I installed it on a virtual floppy. After that I used WinToFlash's create bootable MS-DOS USB drive option to transfer the floppy image to an USB flash drive. Then I tried to boot my computer from it but got only a repeating broken string on screen. After all that I made a virtual hard disk image form the flash drive using this tutorial and tried to boot a virtual machine from it. First time I got same problem as on real computer. I then used the reset option and next time and every time after that OS booted correctly. My question is: How do I figure out what exactly happened to the virtual machine between first and second boot? UPDATE I just created a new VM with default settings for windows XP and it has the same problem that I have on a real computer. I was unable to reproduce the procedure which made the first VM work correctly.

• TFTP Timing Out on Ubuntu VM

  - by valsidalv

  I'm running a Windows 7 PC with VMware installed which has my Ubuntu (10.04 Lucid Lynx). I recently installed a DHCP server and TFTP (Xinet tftpd) using these instructions. I've mapped a network drive so that my Windows has access to all the files in my VM through a 192.x.x.x IP address. I'm trying to throw some custom firmware onto a router. The router has its own built-in TFTP utility that will download the image. It successfully manages to do everything but it is slow because it writes it to flash memory. There is another method that is much quicker because it writes to RAM directly but it must use the TFTP server in Ubuntu. The issue I'm facing is that the Ubuntu TFTP transfer seems to be timing out. The transfer starts but never goes past ~60%. Here's my /etc/xinetd.d/tftp file (similar to a known working config): service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = -s /home/user/tftp/ disable = no cps = 300 2 per_source = 60 } I've done some searching but can't find any parameters for this file to control timeout time or number of retries. The last two arguments (cps, per_source) and completely alien to me (can anyone explain). I have a few possible solutions but the easiest would be to get this TFTP server working. Can anyone help? Either with a timeout configuration or maybe even recommend a different TFTP server? Thanks!

• All virtualhosts serving Apache default files

  - by tj111

  I'm trying to configure Apache as an in-network webserver, and am using the sites-available/sites-enabled feature as opposed to just static vhost files. I set up a couple VirtualHosts, all with a unique DocumentRoot, however request for all the VirtualHosts just serve up the "It's Working!" default file. I can't for the life of me figure out why it won't serve the content out of the correct directory. Here's the contents of the virtualhost directive files, let me know if I need to post more. default (note that apache renames this to 000-default in sites-enabled, so it's not an ordering issue) NameVirtualHost *:80 ServerName emp <VirtualHost *:80> ServerAdmin webmaster@localhost ServerName emp DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

• Blink build with Xcode failed

  - by Merci

  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. Unfortunately googling did not help. There's no documentation on the project site.

• How do I `SUM` by multiple columns in Excel

  - by dwwilson66

  I have a comma delimited file that includes two columns date/time (which imports as Excel's mm/dd/yyyy hh:mm custom format) and status of 1 or 0. The status represents a piece of equipment either being on or off. I'm trying to generate a graph that will show, hours up vs. down by day. CONSIDER: 1/1/2012 00:00, 1 1/1/2012 03:00, 0 1/1/2012 14:00, 1 1/3/2012 00:00, 0 This tells me that the equipment was up for three hours, down for eleven hours, and then up for thirty-four hours (across two calendar days). However, I would like to generate a graph that shows how many hours PER DAY we were up or down. CONSIDER: 1/1 XXXXXXXXXXXXX----------- (up 13, down 11) 1/2 XXXXXXXXXXXXXXXXXXXXXXXX (up 24) To me, it seems that I need to generate a dataset summing HOURS by STATUS by CALENDAR DAY...but I can't seem to find a flavor of pivot table or nested SUM(IF(SUMIF(...))) combination to make it work. Most troubling is accounting for date changes...in my example above, since my uptime starting at 14:00 on 1/1/2012 crosses midnight, I need to know that 10 uptime hours get totalled with 1/1/2012 and 24 uptime hours get totalled with 1/2/2012. I may be able to do something with a calendar list to drive the date summation, but then I need a way to compare 01/01/2012 to 01/01/2012 03:00 as equal. There's got to be a way along the lines of if(INTEGER-PORTIONS-OF-SERIAL-DATES-ARE-EQUAL,TOTAL-HOURS-IF-VALUE-IS_1,0) but nothing's worked so far. Any suggestions? I've been battling this most of the day, and need a fresh perspective. Thanks

• Apache reports a 200 status for non-existent WordPress URLs

  The WordPress .htaccess generally has the following rewrite rules: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> When I access a non-existent URL at my website, this rewrite rule gets hit, redirects to index.php, and serves up my custom 404.php template file. The status code that gets sent back to the client is the correct 404, as shown in this HTTP Live Headers output example: http://www.borngeek.com/nothere/ GET /nothere/ HTTP/1.1 Host: www.borngeek.com {...} HTTP/1.1 404 Not Found However, Apache reports the entire exchange with a 200 status code in my server log, as shown here in a log snippet (trimmed for simplicity): {...} "GET /nothere/ HTTP/1.1" 200 2155 "-" {...} This makes some sense to me, seeing as the original request was redirected to page that exists (index.php). Is there a way to force Apache to report the exchange as a 404? My problem is that bogus requests coming from Bad Guys show up as "successful requests" in the various server statistics software I use (AWStats, Analog, etc). I'd love to have them show up on the Apache side as 404s so that they get filtered out from the stat reports that get generated. I tried adding the following line to my .htaccess, but it had no effect (I'm guessing for the same reason as the previous redirect rules): ErrorDocument 404 /index.php?error=404 Does anyone have a clever way to fix this annoyance? Additional Info: OS is Debian 6.0.4, and Apache version looks to be 2.2.22-3 (hosted on DreamHost) The 404 being sent back to the client is being set by WordPress (i.e. I'm not manually calling header() anywhere)

• Is there a free PDF printer / distiller that creates signable documents?

  - by Coderer

  I've used various methods (mentioned elsewhere on this site) to create PDFs, using a printer driver or converting from PostScript, etc. The common problem is that if I open any of the output files in the newer versions of Adobe Reader, there's an option to "Place Signature" but it's greyed out, or gives an error message that the feature has been disabled for this document. As far as I can tell, there's an option set somewhere in the document metadata that tells Reader "allow the user to sign this document", or don't. None of the free/open source tools that have been been linked to in other SU posts have had this listed as an option (though to be fair I haven't actually downloaded and tried all of them). Is there a tool that does this? Can I just poke a bit with a hex editor somewhere to turn on this functionality? I can sometimes get access to Acrobat Professional to turn on this option, but doing it for every desired case would be more work than I care to do. The current workaround for single-page documents is: Print the document to PDF (possibly via postscript) Open a single-page blank PDF with the "signable" bit turned on in Reader create a custom "stamp" using the Reader markup tools, by importing the printed-to document "stamp" an image of the printed document on the blank page, hoping to get it centered about right place a signature over the document-but-not-really you just stamped This obviously does not scale well at all. It would be much better if I could: Print the document to PDF Drag the document to a simple shortcut / tool / whatever Open the document in Reader Place a signature in the document ETA: Sorry, maybe I should have been clearer -- I'm talking about the certificate-based digital signing available in Adobe Reader, not adding a virtual ink signature. Also, any solution really would have to be available offline.

• WordPress permalinks not working, everything seems fine

  - by javipas

  I have a WordPress blog I've migrated from another CMS, and I've being having a lot of problems with my permalinks structure: lots of articles give a 404, although they are there, somewhere, published. The site is www.muycomputerpro.com (MCP for short), and for example an article that should be found is: http://muycomputerpro.com/Actualidad/Especiales/2009-las-grandes-crecen-en-la-bolsa If I do a search on the search tool at MCP, the result is there (see EnlacesMCP-1.jpg) But when I click on the link, our 404 error page appears (see EnlacesMCP-2.jpg) The weird thing is, the article is published, and the permalink is the right one, as you can see on this screenshot of the WordPress CMS: The permalink (below the title) is correct (http://www.muycomputerpro.com/Actualidad/Especiales/2009-las-grandes-crecen-en-la-bolsa/) but it does not work. In fact, if I try to use the short link (http://www.muycomputerpro.com/?p=5023) the article does not show either. I've accessed my WordPress DB and I've search the article to see if there is something wrong there, but from what I can tell all the fields are OK, here's a screenshot: I really don't know what is causing this. The permalink structure should work (I'm using the "Custom permalink" plugin to preserve the old URLs that had a alphanumeric code at the end of the postname) and the permalink config on wordpress is "/%postname%/". I really need help :(

• How to make emacs accept UTF-8 from the keyboard

  - by Brent.Longborough

  My friends have persuaded me to "try again" (about the 5th time in about 12 years) with emacs. I'm currently suffering a little, and need help with emacs + utf-8. I'm running the 23.3.1 emacs gui on Windows 7 with my own custom keyboard layout (built with MS Keyboard Layout Creator). The layout has a full ISO-8859-1 (Latin-1) character set, plus some additional characters from ISO-8859-9 (Latin-5, gis etc for Turkish) and w for Welsh (don't know where that one lives). In my .emacs, I have (blindly) added these lines: ;; key board / input method settings (setq locale-coding-system 'utf-8) (set-terminal-coding-system 'utf-8) (set-keyboard-coding-system 'utf-8) (set-language-environment 'UTF-8) ; prefer utf-8 for language settings Now, when I enter characters from ISO Latin-1 from the keyboard, they are accepted without problems, but characters from outside Latin-1 are "translated" to an approximate character in Latin-1. Thus, for example, Latin-5 "g" gets converted to a plain "g". Cutting and pasting, however, work fine. Can anyone tell me what I'm doing wrong? I should like to make everything I do with emacs utf-8 with BOM.

• Is it possible to add/register an MIB for the Windows built-in SNMP service?

  - by michielvoo

  I need to build monitoring into an existing .NET application. I will use SNMP to send the application's status to the Windows SNMP service. I have used a .NET library to create the SNMP SET request according to the MIB that I have been provided with, and with the correct community. My code now sends multiple 'variables' in a SET request, for example: Id: ".1.3.6.1.4.1.43607.1.1.1.1.1" (ObjectIdentifier) Data: 42 (Integer32) On my machine I have enabled the SNMP service, configured a community with READ/WRITE permissions, and added localhost to the list of hosts to accept requests from. When I send the SET request I get a response, but it has error status 17 which, according to MSDN means SNMP_ERRORSTATUS_NOTWRITABLE. The response also has error index set to 8, which is the number of variables I send. If I send 7 variables, the error index is set to 7. I think the problem is that the Windows SNMP service is preconfigured to only accept SET requests for a fixed set of MIBs. How can I get the Windows SNMP service to 'accept' my custom MIB SET request? Edit: I downloaded and installed the Windows Server 2003 Resource Kit and tried to 'compile' the MIB file with mibcc.exe ("SNMP MIB Compiler") but I have not been able to compile any MIB files (even the most basic ones like SNMPv2-SMI.mib).

• How can I stop IIS7 (integrated mode) from reporting a 404 before I get a chance to handle it?

  - by Gary McGill

  I have an ASP.NET MVC 2 application running on IIS7 in integrated mode. I'm trying to do my own 404 handling, but IIS7 seems to be intercepting the error and returning its own 404 message to the client before I get a chance to handle it. I'm not having much luck coming at the problem from a programming perspective over on Stack Overflow, so I wondered if maybe it's a configuration problem. Is there something I have to do to tell IIS to let me handle my own errors? (I'm trying to use Application_Error in my global.asax but it's not even getting there). There is a custom error page defined (at the machine level, I think) for 404 but when I tried removing that it didn't really help - it simply showed a bald one-liner message instead. My code still didn't get a look in. Is it perhaps something to do with the routing? Maybe the "mysite.com/nosuchpage" URL isn't being routed to me and that's why I don't get a chance to intercept it? Do I need to do something so that ALL requests get routed through my app?

• What kernel modules are required for wi-fi to work?

  - by Leonid Shevtsov

  My custom-built 2.6.32 kernel cannot connect to any WPA-protected network. The kernel includes (probably?) everything that should be needed for wifi, including IPv4 network support (IPv6 is disabled), the ath5k wireless driver (which is used in the generic Ubuntu 2.6.31 kernel) and all crypto APIs. The card is being detected, however, iwlist scan returns wlan0 Failed to read scan data : Network is down and network-manager log says <info> (wlan0): driver supports SSID scans (scan_capa 0x01). <info> (wlan0): new 802.11 WiFi device (driver: 'ath5k') <info> (wlan0): exported as /org/freedesktop/NetworkManager/Devices/1 <info> (wlan0): now managed <info> (wlan0): device state change: 1 -> 2 (reason 2) <info> (wlan0): bringing up device. <info> (wlan0): preparing device. <info> (wlan0): deactivating device (reason: 2). supplicant_interface_acquire: assertion `mgr_state == NM_SUPPLICANT_MANAGER_STATE_IDLE' failed <info> modem-manager is now available <WARN> default_adapter_cb(): bluez error getting default adapter: The name org.bluez was not provided by any .service files <info> Trying to start the supplicant... <info> (wlan0): supplicant manager state: down -> idle <info> (wlan0): device state change: 2 -> 3 (reason 0) <WARN> nm_supplicant_interface_add_cb(): Unexpected supplicant error getting interface: wpa_supplicant couldn't grab this interface. The exact same configuration works with the generic kernel. Is anything except wifi and crypto api needed for wi-fi to work?

• Linux VLAN Bridge

  - by raspi

  I have home network with VLANs, one for LAN, one for WLAN and one for internet. I'd like to use bridging so that instead of configuring these same VLANs to every machine, they had own VLAN ID and bridges were LAN, WLAN and internet. I've tried it but for some reason keep-alive/ttl seems to get broken because SSH sessions etc suddenly disconnects. We have this same setup working in workplace for 4+ years with 100+ customers but it's custom firewall/router hardware so accessing it is impossible. I know that it runs Linux. So what is Debian/Ubuntu default network settings doing wrong or is it just NIC driver/hw problem? I've tried to mess araund with ttl etc settings without any luck. The bad stuff is happening in the bridge because current VLAN-only setup works fine. interfaces: auto lo iface lo inet loopback # The primary network interface allow-hotplug eth0 allow-hotplug eth1 iface eth0 inet static iface eth1 inet static auto vlan111 auto vlan222 auto vlan333 auto vlan444 auto br0 auto br1 auto br2 # LAN iface vlan111 inet static vlan_raw_device eth0 # WLAN iface vlan222 inet static vlan_raw_device eth0 # ADSL Modem iface vlan333 inet static vlan_raw_device eth1 # Internet iface vlan444 inet static vlan_raw_device eth0 # LAN bridge iface br0 inet static address 192.168.0.1 netmask 255.255.255.0 bridge_ports eth0.111 bridge_stp on # Internet bridge iface br1 inet static address x.x.x.x netmask x.x.x.x gateway x.x.x.x bridge_ports eth1.333 eth0.444 bridge_stp on post-up iptables -t nat -A POSTROUTING -o br1 -j MASQUERADE pre-down iptables -t nat -D POSTROUTING -o br1 -j MASQUERADE # WLAN bridge iface br2 inet static address 192.168.1.1 netmask 255.255.255.0 bridge_ports eth0.222 bridge_stp on Sysctl: net.ipv4.conf.default.forwarding=1
