• LdapErr: DSID-0C0903AA, data 52e: authenticating against AD '08 with pam_ldap

  - by Stefan M

  I have full admin access to the AD '08 server I'm trying to authenticate towards. The error code means invalid credentials, but I wish this was as simple as me typing in the wrong password. First of all, I have a working Apache mod_ldap configuration against the same domain. AuthType basic AuthName "MYDOMAIN" AuthBasicProvider ldap AuthLDAPUrl "ldap://10.220.100.10/OU=Companies,MYCOMPANY,DC=southit,DC=inet?sAMAccountName?sub?(objectClass=user)" AuthLDAPBindDN svc_webaccess_auth AuthLDAPBindPassword mySvcWebAccessPassword Require ldap-group CN=Service_WebAccess,OU=Groups,OU=MYCOMPANY,DC=southit,DC=inet I'm showing this because it works without the use of any Kerberos, as so many other guides out there recommend for system authentication to AD. Now I want to translate this into pam_ldap.conf for use with OpenSSH. The /etc/pam.d/common-auth part is simple. auth sufficient pam_ldap.so debug This line is processed before any other. I believe the real issue is configuring pam_ldap.conf. host 10.220.100.10 base OU=Companies,MYCOMPANY,DC=southit,DC=inet ldap_version 3 binddn svc_webaccess_auth bindpw mySvcWebAccessPassword scope sub timelimit 30 pam_filter objectclass=User nss_map_attribute uid sAMAccountName pam_login_attribute sAMAccountName pam_password ad Now I've been monitoring ldap traffic on the AD host using wireshark. I've captured a successful session from Apache's mod_ldap and compared it to a failed session from pam_ldap. The first bindrequest is a success using the svc_webaccess_auth account, the searchrequest is a success and returns a result of 1. The last bindrequest using my user is a failure and returns the above error code. Everything looks identical except for this one line in the filter for the searchrequest, here showing mod_ldap. Filter: (&(objectClass=user)(sAMAccountName=ivasta)) The second one is pam_ldap. Filter: (&(&(objectclass=User)(objectclass=User))(sAMAccountName=ivasta)) My user is named ivasta. However, the searchrequest does not return failure, it does return 1 result. I've also tried this with ldapsearch on the cli. It's the bindrequest that follows the searchrequest that fails with the above error code 52e. Here is the failure message of the final bindrequest. resultcode: invalidcredentials (49) 80090308: LdapErr: DSID-0C0903AA, comment: AcceptSecurityContext error, data 52e, v1772 This should mean invalid password but I've tried with other users and with very simple passwords. Does anyone recognize this from their own struggles with pam_ldap and AD? Edit: Worth noting is that I've also tried pam_password crypt, and pam_filter sAMAccountName=User because this worked when using ldapsearch. ldapsearch -LLL -h 10.220.100.10 -x -b "ou=Users,ou=mycompany,dc=southit,dc=inet" -v -s sub -D svc_webaccess_auth -W '(sAMAccountName=ivasta)' This works using the svc_webaccess_auth account password. This account has scan access to that OU for use with apache's mod_ldap.

• List/remove files, with filenames containing string that's "more than a month ago"?

  - by Martin Tóth

  I store some data in files which follow this naming convention: /interesting/data/filename-YYYY-MM-DD-HH-MM How do I look for the ones with date in file name < now - 1 month and delete them? Files may have changed since they were created, so searching according to last modification date is not good. What I'm doing now, is filter-ing them in python: prefix = '/interesting/data/filename-' import commands names = commands.getoutput('ls {0}*'.format(prefix)).splitlines() from datetime import datetime, timedelta all_files = map(lambda name: { 'name': name, 'date': datetime.strptime(name, '{0}%Y-%m-%d-%H-%M'.format(prefix)) }, names) month = datetime.now() - timedelta(days = 30) to_delete = filter(lambda item: item['date'] < month, all_files) import os map(os.remove, to_delete) Is there a (oneliner) bash solution for this?

• Filtering serial port io

  - by mr odus

  I am currently working on a project where I communicate with hardware via a com port on its respective pc(win xp or 7) It is a fairly large project and sifting through the log file can be a bit of pain. This is my current setup. I use putty to do the actual serial communication, and write it to a log file. Then using MinGW Msys I filter it using tail -f "puttyLog" | grep -i "search term" Is there a better way to do this? I mean specifically filtering the input in realtime. Not that mine is terrible, but it still involves having to read from a log and sometimes there have been hangups where it will be delayed for a minute or 2. I have used software in the past with a main io window and then internal filter panels, but can no longer remember or find it.

• PowerShell - Limit the search to only one OU

  Ive got this cmdlet and I'd like to limit the results to only one OU: Get-ADUser -Filter {(Enabled -eq $false)} | ? { ($_.distinguishedname -notlike '*Disabled Users*') } Now Ive tried to use -searchbase "ou=FirstOU,dc=domain,dc=com" But if I use -SearchBase I get this error: Where-Object : A parameter cannot be found that matches parameter name 'searchb ase'.

• DVD stops working in windows 7 64 bit

  - by Skadlig

  I have the same problem as described in this question: http://superuser.com/questions/105928/dvd-cd-rom-drives-stop-working-in-windows-7 I know I have got some games that are using starforce and/or securerom. What I don't have is the upper and lower filter in my registry tag. Oh and a reboot temporarily fixes my problem. After a random time though it goes missing again. I found a Microsoft knowledge base article regarding this but since I didn't have the filter tags they couldn't help me. Does anyone have any other tips bar removing the despicable drm:s? I would like to go on playing my games so that is not really an option for me.

• route to vpn based on destination

  - by inquam

  I have a VPN connection on a Windows 7 machine. It's set up to connect to a server in US. Is it possible, and if so how, to setup so that .com destinations uses the vpn interface and .se destinations uses the "normal" connection? Edit (clarification): This is for outbound connections. I.e. the machine conencts to a server on foo.com and uses the VPN and the machine connects to bar.se and uses the "normal" interface. Let's say foo.com has an IP filter that ensures users are located in USA, if I go through the VPN I get a US ip and everything is fine. But tif all traffic goes this way the bar.se server that has a IP filter ensuring users are in Sweden will complain. So I want to route the traffic depending on server location. US servers through VPN and others through the normal interface.

• Wireshark Not Displaying Packets From Other Network Devices, Even in Promisc Mode

  - by eb80

  System Setup: 1. MacBook running Mountain Lion. 2. Wireshark installed and capturing packets (I have "capture all in promiscuous mode" checked) 3. I filter out all packets with my source and destination IP using the following filter ("ip.dst != 192.168.1.104 && ip.src != 192.168.1.104") 4. On the same network as the MacBook, I use an Android device (connecting via WiFi) to make HTTP requests. Expected Results: 1. Wireshark running on the MacBook sees the HTTP request from the Android device. Actual Results: 1. I only see SSDP broadcasts from 192.168.1.1 Question: What do I need to do so that Wireshark, like Firesheep, can see and use the packets (particularly HTTP) from other network devices on the same network?

• Transparently decompressing data in archive to allow greater compression later

  - by Vi.

  I have, for example, filesystem image which have some compressed files (with weak compression such as gzip), for example, manpages or archives with the same uncompressed content nearby. How to pre-filter the data to "expand" compressed data to plain form (to re-compress it with strong compression) and then post-filter after decompression to restore original "semi-compressed" image? SHA-1 match is advices but not strictly required (but the resulting image must work, e.g. re-compressed files should not grow too much, be decompressible etc.) Like improving compression ratio by reversing weak compression algorithms. Are there programs for this?

• Postfix not delivering mails

  - by Sotocan

  Hi all, I have problems with a recently configured postfix MTA. When postfix starts the following warning appears: "postfix/qmgr[5078]: warning: connect to transport private/filter: No such file or directory" I have amavis-new as a content-filter, but even if I comment-out the relevant line, the warning appears. As a result (I think), of the above, I get errors like below, for every virtual domain that I have: "postfix/error[5080]: 254851834107: to=, relay=none, delay=13082, delays=13082/0.01/0/0.01, dsn=4.3.0, status=deferred (mail transport unavailable)" The good news for me, is that somehow I managed to fix that (don't ask me how!!!!) The problem is that now I have 50 or so mails, that were affected by the aforementioned problem, in the mail-queue... If I "postqueue -f " I get the same style of error as before (mail transport unavailable)...however new mails are delivered to their final destination properly... Any suggestions? Kind regards. P.S. Local mail delivery from/to Unix and virtual users, was OK write from the beginning!

• Lots of dropped packages when tcpdumping on busy interface

  - by Frands Hansen

  My challenge I need to do tcpdumping of a lot of data - actually from 2 interfaces left in promiscuous mode that are able to see a lot of traffic. To sum it up Log all traffic in promiscuous mode from 2 interfaces Those interfaces are not assigned an IP address pcap files must be rotated per ~1G When 10 TB of files are stored, start truncating the oldest What I currently do Right now I use tcpdump like this: tcpdump -n -C 1000 -z /data/compress.sh -i any -w /data/livedump/capture.pcap $FILTER The $FILTER contains src/dst filters so that I can use -i any. The reason for this is, that I have two interfaces and I would like to run the dump in a single thread rather than two. compress.sh takes care of assigning tar to another CPU core, compress the data, give it a reasonable filename and move it to an archive location. I cannot specify two interfaces, thus I have chosen to use filters and dump from any interface. Right now, I do not do any housekeeping, but I plan on monitoring disk and when I have 100G left I will start wiping the oldest files - this should be fine. And now; my problem I see dropped packets. This is from a dump that has been running for a few hours and collected roughly 250 gigs of pcap files: 430083369 packets captured 430115470 packets received by filter 32057 packets dropped by kernel <-- This is my concern How can I avoid so many packets being dropped? These things I did already try or look at Changed the value of /proc/sys/net/core/rmem_max and /proc/sys/net/core/rmem_default which did indeed help - actually it took care of just around half of the dropped packets. I have also looked at gulp - the problem with gulp is, that it does not support multiple interfaces in one process and it gets angry if the interface does not have an IP address. Unfortunately, that is a deal breaker in my case. Next problem is, that when the traffic flows though a pipe, I cannot get the automatic rotation going. Getting one huge 10 TB file is not very efficient and I don't have a machine with 10TB+ RAM that I can run wireshark on, so that's out. Do you have any suggestions? Maybe even a better way of doing my traffic dump altogether.

• Filtering ToDo List in Outlook 2010 with multiple Exchange accounts

  - by David LaRocque

  I'm trying to figure out how to get the ToDo list filtered for just one account? I've tried customizing the view, and using the advanced filter to get just one Oulook Data file, but once I do that the filter goes bonkers and I get all sorts of results! I know it's a combination of email flags and true tasks, and tried combining filters to pull those conditions together, and simply can't get it to cooperate. Before 2010, when the only way to get multiple mailboxes was to add additional mailboxes to the primary account, the task list pulled from just the primary account - but of course, the secondary accounts are not cached and available offline.

• Filtering downloading a file

  - by Ozgun Sunal

  people. i know there are several types of firewalls operating at different layers of OSI. ACLs(layer 3 firewalls filter based on port numbers and IP addresses), SPI(which examines the patterns of data at layer 3 and realise that data content is malicious or not) and application layer firewalls which is capable of understanding the data at that level. Considering this, i'll give an example and learn what i need to do. Lets say, we have a computer has access to the Internet. i want to download a file or display a web page from a website but block access to the another website/s or downloading. To do this, i cant block access to the web browser on the 3rd party firewall bcos that will shut down all access. ACLs wont already do it. So, which kind of firewall will make it possible to filter specific traffic and how?

• DKIM sign any outgoing mail as the same domain. is possibly?

  - by Felipe Alcacibar

  I have a website, and the users recommend via email to another persons, so the mail come from my site, but I need to appear the user as sender, but "via" mydomain. The logically and what lists management software and companies do is differ the "MAIL FROM" SMTP command and the "From" header (like mailchimp, for example). So I want to DKIM sign a mail with mydomain.com, even if the From header says another domain. is possibly this? I am using postfix with Debian GNU/Linux, and in this case using dkim-filter and dk-filter.

• Deny IIS6 web request based on URL parameters?

  - by user21146

  I've got a legacy app running a third-party ecommerce system under IIS6. Some spammers recently discovered a bad security vulnerability in one of the store's forms, which are allowing them to send arbitrary emails from our system. Unfortunately, this store "feature" is built into the default.aspx page's code-behind and I have no way to disable it without shutting down the store. How can I filter out URL request with a given querystring parameter? ie, I want to filter out requests to: http://www.mysite.com/store/?id=SendSpam based on the "SendSpam" string.

• Monitor disk I/O for specific drive in OS X

  - by raffi

  In my Macbook Pro, I have two internal drives and I've connected a third drive via USB in enclosure. I am currently doing a secure wipe of the external drive and I was interested in seeing what the disk I/O was for that particular drive, but when I use Activity Monitor I only see the total disk usage for all drives combined. Is there any way to monitor a specific drive's total I/O, preferably via a built-in or free method? I don't want to filter by process ID. I just want to filter by mounted disk.

What you can try: Check your Internet connection. Try visiting another website to make sure you are connected. Retype the address. Go back to the previous page. I can get to google fine, so it is not the internet connection.... But this message gives me nothing to work on. How can I get more info as to why my page is not working? I tried going to IIS Mananger and right clicking on the site and selecting browse. But my site is an HTTPS site so that does not work. Any ideas would be great.

• Try out Windows Phone 7 on your PC today

  - by Matthew Guay

  Anticipation has been building for the new Windows Phone 7 Series ever since Microsoft unveiled it at the Mobile World Congress in February.  Now, thanks to free developer tools, you can get a first-hand experience of the basic Windows Phone 7 Series devices on your PC. Windows Phone 7 Series represents a huge change in the mobile field for Microsoft, bringing the acclaimed Zune HD UI to an innovative phone platform.  Windows Mobile has often been criticized for being behind other Smartphone platforms, but Microsoft seeks to regain the lead with this new upcoming release.  A platform must have developers behind it to be useful, so they have released a full set of free development tools so anyone can make apps for it today.  Or, if you simply want to play with Windows Phone 7, you can use the included emulator to try out the new Metro UI.  Here’s how to do this today on your Vista or 7 computer. Please note: These tools are a Customer Technology Preview release, so only install them if you’re comfortable using pre-release software. Getting Started First, download the Windows Phone Developer Tools CTP (link below), and run the installer.  This will install the Customer Technology Preview (CTP) versions of Visual Studio 2010 Express for Windows Phone, Windows Phone Emulator, Silverlight for Windows Phone, and XNA 4.0 Game Studio on your computer, all of which are required and cannot be installed individually. Accept the license agreement when prompted. Click “Install Now” to install the tools you need.  The only setup customization option is where to save the files, so choose Customize if you need to do so. Setup will now automatically download and install the components you need, and will additionally download either 32 or 64 bit programs depending on your operating system. About halfway thorough the installation, you’ll be prompted to reboot your system.  Once your computer is rebooted, setup will automatically resume without further input.   When setup is finished, click “Run the Product Now” to get started. Running Windows Phone 7 on your PC Now that you’ve got the Windows Phone Developer tools installed, it’s time to get the Windows Phone emulator running.  If you clicked “Run the Product Now” when the setup finished, Visual Studio 2010 Express for Windows Phone should have already started.   If not, simply enter “visual studio” in your start menu search and select “Microsoft Visual Studio 2010 Express for Windows Phone”. Now, to run the Windows Phone 7 emulator, we have to test an application.  So, even if you don’t know how to program, we can open a phone application template, and then test it to run the emulator.  First, click New Project on the left hand side of the front page. Any of the application templates would work for this, but here let’s select “Windows Phone Application”, and then click Ok. Here’s your new application template, which already contains the basic phone application framework.  This is where you’d start if you want to develop a Windows Phone app, but for now we just want to see Windows Phone 7 in action. So, to run the emulator, click Debug in the menu and then select Start Debugging. Your new application will launch inside the Windows Phone 7 Series emulator.  The default template doesn’t give us much, but it does show an example application running in Windows Phone 7.   Exploring Windows Phone 7 Click the Windows button on the emulator to go to the home screen.  Notice the Zune HD-like transition animation.  The emulator only includes Internet Explorer, your test application, and a few settings. Click the arrow on the right to see the available applications in a list. Settings lets you change the theme, regional settings, and the date and time in your emulator.  It also has an applications settings pane, but this currently isn’t populated. The Time settings shows a unique Windows Phone UI. You can return to the home screen by pressing the Windows button.  Here’s the Internet Explorer app running, with the virtual keyboard open to enter an address.  Please note that this emulator can also accept input from your keyboard, so you can enter addresses without clicking on the virtual keyboard. And here’s Google running in Internet Explorer on Windows Phone 7. Windows Phone 7 supports accelerometers, and you can simulate this in the emulator.  Click one of the rotate buttons to rotate the screen in that direction. Here’s our favorite website in Internet Explorer on Windows Phone 7 in landscape mode. All this, running right inside your Windows 7 desktop… Developer tools for Windows Phone 7 Although it may be fun to play with the Windows Phone 7 emulator, developers will be more excited to actually be able to create new and exciting apps for it.  The Windows Phone Developer Tools download includes Visual Studio Express and XNA Game Studio 4.0 which lets you create enticing games and apps for Windows Phones.  All development for Windows Phones will be in C#, Silverlight, and the XNA game framework.  Visual Studio Express for Windows Phone includes templates for these, and additionally has code samples to help you get started with development. Conclusion Many features are still not functional in this preview version, such as the search button and most of the included applications.  However, this still gives you a great way to experience firsthand the future of the Windows Phone platform.  And, for developers, this is your chance to set your mark on the Windows Phone 7 Series even before it is released to the public.  Happy playing and developing!

• How Mary Meeker’s Latest Findings May Make You Re-Imagine Commerce

  - by Brenna Johnson-Oracle

All 164 slides are jam-packed with pretty much everything you need to know about the state of the Internet. And as luck would have it, Oracle is staying ahead of these trends (but we’ll talk about that later). There were a few surprises, some stats to solidify what you likely already know, and Meeker’s novel observations about where we are all going. What interested me the most is not only how people are engaging in their personal lives, but how they engage with brands. As you could probably predict, Internet usage growth is slowing while tablet user and mobile data traffic growth continue their meteoric rise around the globe, with tremendous growth in underpenetrated markets like China, India, Brazil and Indonesia. Now hold those the “Internet is dead” comments. Keep in mind there’s still plenty of room to grow, and a multiscreen model is Meeker’s vision for our future. Despite 1.5x YOY growth for mobile traffic, mobile still only makes up about 23% of all traffic today. With tablet shipments easily outpacing figures for PCs even at their height (in 2007), mobile will only continue on it’s path, but won’t be everything to everyone. Mobile won’t replace every touchpoint, it’s just created our shorter attention spans and demand for simpler, more personal experiences. As Meeker points out TVs, tablets, PCs, and smartphones are used for different activities at present, but lines will blur (for example, 84% of smartphones owners use their device while watching TV). Day-to-day activities are being re-imagining through simple, beautiful user experiences. It seems like every day I discover a new way a brand/site/app made the most mundane or mounting task enjoyable and frictionless – and I’m not alone. Meeker points out the evolution of how we do everything from how we communicate, get information, use money, meet someone, get places, order a meal, and consume media is all done through new user interfaces that make day-to-day tasks simpler. This movement has caused just about everyone’s patience for a poor UX to take a nosedive. And it’s not just the digital user experience, technology is making a lot of people’s offline lives easier, and less expensive. Today 47% of online shopping utilizes free shipping— nearly half. And Meeker predicts same day local delivery will be the “next big thing” (and you can take a guess on who will own that). Content, Community and Commerce creates the “Internet Trifecta.” Meeker pointed out that when content, communities and commerce occur in a single experience it’s embraced by consumers, which translates to big dollars for brands. The magic happens when consumers can get inspired, research, and buy in a single experience. As the buying cycle has changed and touchpoints (Web, mobile, social, store) are no longer tied to “roles” or steps in the customer journey, brands must make all experiences (content and commerce) available in a single, adaptable experience. (We at Oracle Commerce have a lot to say on this topic – stay tuned!) And in what Meeker calls the “biggest re-imagination of all:” consumers enabled with smartphones and sensors are creating troves of findable and sharable data, which she says is in the early stages, by growing rapidly. She notes that transparency and patterns of consumers with this hardware (FYI - there are up to 10 sensors embedded in smartphones now) has created a Big Data treasure chest to be mined to improve business and the life of the consumer. The opportunities are endless. So what does it all mean for a company doing business online? Start thinking about how you can: Re-imagine your experience. Not your online experience and your mobile experience and your social experience – your overall experience. When consumers can research, buy, and advocate from anywhere (and their attention spans are at an all-time low) channels don’t exist. Enable simple and beautiful interactions informed by all of the online and offline data you leverage across your enterprise. Ethically leverage the endless supply of data (user generated content, clicks, purchases, in-store behavior, social activity) to make experiences more beautiful, more accurate, and more personalized (not to mention, more lucrative for you). Re-imagine content and commerce. Content and commerce must co-exist in a single destination where shoppers can get inspired, explore, research, share, and purchase in a collective experience. Think of how you can deliver an experience where all types of experiences (brand stories and commerce) adapt to every customer need. (Look for more on this topic coming soon). Re-imagine your reach. Look to Meeker’s findings to see how the global appetite for digital experiences is growing, but under-served in many places (i.e.: India, Mexico, Indonesia, Brazil, Philippines, etc.). Growing your online business to a new geography doesn’t have to mean starting from scratch or having an entirely new team manage the new endeavor. Expand using what you’ve already built in a multisite framework, with global language support. And of course, make sure it’s optimized for mobile! Re-imagine the possible. After every Meeker report, I’m always left with the thought “we are just at the beginning.” Everyday there is more data, more possibilities, more online consumers, and more opportunities to use new latest technology to get closer to your customers and be more successful. There’s a lot going on in our Product Development and Product Innovations groups to automate innovation for our customers, so that they can continue to stay ahead of these trends, without disrupting their business. Check out a recent interview with our Innovations Team on some of these new possibilities. Staying on track despite the seemingly endless possibilities out there is the hard part. Prioritizing where you will focus based on your unique brand promise, customer and goals is what you do best.

• How would i down-sample a .wav file then reconstruct it using nyquist? - in matlab [closed]

  - by martin

  This is all done in MatLab 2010 My objective is to show the results of: undersampling, nyquist rate/ oversampling First i need to downsample the .wav file to get an incomplete/ or impartial data stream that i can then reconstuct. Heres the flow chart of what im going to be doing So the flow is analog signal - sampling analog filter - ADC - resample down - resample up - DAC - reconstruction analog filter what needs to be achieved: F= Frequency F(Hz=1/s) E.x. 100Hz = 1000 (Cyc/sec) F(s)= 1/(2f) Example problem: 1000 hz = Highest frequency 1/2(1000hz) = 1/2000 = 5x10(-3) sec/cyc or a sampling rate of 5ms This is my first signal processing project using matlab. what i have so far. % Fs = frequency sampled (44100hz or the sampling frequency of a cd) [test,fs]=wavread('test.wav'); % loads the .wav file left=test(:,1); % Plot of the .wav signal time vs. strength time=(1/44100)*length(left); t=linspace(0,time,length(left)); plot(t,left) xlabel('time (sec)'); ylabel('relative signal strength') **%this is were i would need to sample it at the different frequecys (both above and below and at) nyquist frequency.*I think.*** soundsc(left,fs) % shows the resaultant audio file , which is the same as original ( only at or above nyquist frequency however) Can anyone tell me how to make it better, and how to do the various sampling at different frequencies?
