• How can I enable anonymous access to a Samba share under ADS security mode?

  - by hemp

  I'm trying to enable anonymous access to a single service in my Samba config. Authorized user access is working perfectly, but when I attempt a no-password connection, I get this message: Anonymous login successful Domain=[...] OS=[Unix] Server=[Samba 3.3.8-0.51.el5] tree connect failed: NT_STATUS_LOGON_FAILURE The message log shows this error: ... smbd[21262]: [2010/05/24 21:26:39, 0] smbd/service.c:make_connection_snum(1004) ... smbd[21262]: Can't become connected user! The smb.conf is configured thusly: [global] security = ads obey pam restrictions = Yes winbind enum users = Yes winbind enum groups = Yes winbind use default domain = true valid users = "@domain admins", "@domain users" guest account = nobody map to guest = Bad User [evilshare] path = /evil/share guest ok = yes read only = No browseable = No Given that I have 'map to guest = Bad User' and 'guest ok' specified, I don't understand why it is trying to "become connected user". Should it not be trying to "become guest user"?

• Why do digits in bash script names screw up path lookups?

  - by cannikin

  I've got a simple script that lists a bunch of EC2 servers and automates me connecting to them. This script lives at ~/bin/ec2 My PATH looks something like: /Users/rob/bin:/Users/rob:/usr/local/bin:/usr/local/sbin:/opt/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin Whenever I call ec2 I get: -bash: /Users/rob/ec2: No such file or directory Unless I give it the full path, then it'll work. If I rename the script to just ec then I can run it from anywhere like expected. Have digits in script names always been a problem like this? I'm on Mac OSX.

• Would You Pay for Smartphone OS Updates? [Poll]

  - by Jason Fitzpatrick

  For most phone ecosystems, manufacturer/carrier provided updates are few and far between (or outright nonexistent). To get access to mobile OS updates, would you open your wallet? While iPhone users are used to regular (and free) OS updates, the rest of us our largely left out in the cold. Over at ExtremeTech, Ryan Whitwam argues that we should be willing to pay for smartphone OS updates. The core of his argument is updates cost money and there is no financial incentive for carriers like Sprint and Verizon to turn back to their supplies (say, Motorola or LG) and pay them to provide an update pack for a phone they stopped selling last quarter. He writes: It might be hard to swallow, but the manufacturer of your phone is out to make money for its shareholders. The truth of the matter is that you’re not even the customer; the carrier is. Carriers buy thousands of phones at a time, and unless the carrier wants an update, there won’t be one because there is no one else to pay for it. Imagine if, instead of burning money for little or no benefit, an OEM actually had a financial incentive to port ICS to its older devices. Instantly, the idea of updating phones goes from the customer service back-burner to the forefront of a company’s moneymaking strategy. If the system proves a success, carriers could get involved and have a taste of the update fees as compensation for deploying the update over the air. This is more viable now than ever before thanks to the huge number of Android phones in the market. Samsung, for example, has sold over 30 million Galaxy S II phones since last summer. It has just started rolling Android 4.0 updates out to some countries, but most users are still waiting. If it charged just $10 for access to the update, that would be $150 million if only half of all users wanted an official update.

• Windows 8 Media Center Pack Install Fails with DoTransmogrify failed due to error 0x80070011

• Understanding each other in web development

  - by Pete Hotchkin

  During my career I have been lucky enough to work in several different roles within web development with many extremely talented people, from incredible designers who were passionate about the placement of every pixel right through to server administrators and DBAs who were always measuring the improvements they were making to their queries in the smallest possible unit. The problem I always faced was that more often than not I was stuck in the middle trying to mediate between these different functions and enable each side to understand the other’s point of view. The main areas of contention that there have always been between these functional groups in my experience have been at 2 key points: during the build phase and then when there is a problem post-build. During both of these times it is often easier for someone to pass the buck onto someone else than spend the time to understand the other person’s perspective. Below is a quick look at two upcoming tools that will not only speed up the build phase for each function, but  also help when it comes to the issues faced once a site has been pushed live. In my experience a web project goes through several phases of development. The first of these is design, generally handled as Photoshop files which are then passed onto a front-end developer. This is the first point at which heated discussions can arise. One problem I’ve seen several times is that the designer doesn’t fully understand the platform constraints that need to be considered, and as a result has designed something that does not translate very well or is simply not possible. Working at Red Gate, I am lucky enough to be able to meet some amazing people and this happened just the other day when I was introduced to Neil Kinnish and Pete Nelson, the creators of what I believe could be a great asset in this designer-developer relationship, Mixture. Mixture allows the front end developer to quickly prototype a web page with built-in frameworks such as bootstrap. It’s not an IDE however, it just sits there in the background and monitors the project files in the background so every time you save a file from your favorite IDE, it will compile things like LESS, compact your JavaScript and the automatically refresh your test browser so you can see the changes instantly. I think one of the best parts of this however is a single button that pushes the changed files up to the web so the designer can instantly see how far the developer has got and the problem that he is facing at that time without the need to spend time setting up a remote server. I can see this being a real asset to remote teams where there needs to be a compromise between the designer and the front-end developer, or just to allow the designer to see how the build is progressing and suggest small alterations. Once the design has been built into the front end the designer’s job is generally done and there are no other points of contention between the designer and the other functions involved in building these web projects. As the project moves into the stage of integrating it into the back end and deploying it to the production server other functions start to be pulled in and other issues arise such as the back-end developer understanding the frameworks that they are using such as the routes that are in place in an MVC application or the number of database calls that the ORM layer is actually making. There are many tools out there that can actually help with these problems such as mini profiler that gives you a quick snapshot of what is going on directly in the browser. For a slightly more in-depth look at what is happening and to gain a deeper understanding of an application you may be working on though, you may want to consider Glimpse. Created by Nik and Anthony, it is an application that sits at the bottom of your browser (installed via NuGet) which can show you information about how your application is pieced together and how the information on screen is being delivered as it happens. With a wealth of community-built plugins such as one for nHibernate and linq2SQL (full list of plugins on NuGet). It can be customized directly to your own setup to truly delve into the code to see what is happening, and can help to reduce the number of confusing moments about whether it is your code that is going wrong or whether there is something more sinister happening directly on the server. All the tools that I have mentioned in this post help to do one thing above all, and that is to ease the barrier of understanding between the different functions that are involved in building and maintaining a web application. In my experience it is very easy to say “Well, that’s not my problem”, simply because the two functions involved don’t truly understand the other’s point of view. Software should not only be seen as a way to streamline our own working process or as a debugging tool but also a communication aid to improve the entire lifecycle of a web project. Glimpse is actually the project that I am the designer on and I would love to get your feedback if you do decide to try it out or if you would like to share your own experiences of working on web projects please fill in your details at https://www.surveymk.com/s/joinGlimpse  or add a comment below and I will get in touch with you.

• Setting Up IRM Test Content

  - by martin.abrahams

  A feature of the 11g IRM Server that sometimes gets overlooked is the ability to set up some test content that any IRM user can access to verify that their IRM Desktop can reach the server, authenticate successfully, and render protected content successfully. Such test content is useful for new users, and in troubleshooting scenarios. Here's how to set up some test content... In the management console, go to IRM - Administration - Test Content, as shown. The console will display a list of test content - initially an empty list. Use the Add option to specify the URL of a document or image, and define one or more labels for the test content in whichever languages your users favour. Note that you do not need to seal the image or document in order to use it as test content. Nor do you need to set up any rights for the test content. The IRM Server will handle the sealing and rights assignment automatically such that all authenticated users are authorised to view the test content. Repeat this process for as many different types of content as you would like to offer for test purposes - perhaps a Word document, a PDF document, and an image. To keep things simple the first time I did this, I used the URL of one of the images in the IRM Server's UI - so there was no problem with the IRM Server being able to reach that image. Whatever content you want to use, the IRM Server needs to be able to reach it at the URL you specify. Using Test Content Open a browser and browse to the URL that the IRM Desktop normally uses to access the IRM Server, for example: http://irm11g.oracle.com/irm_desktop If you are not sure, you can find this URL in the Servers tab of the IRM Options dialog. Go to the Test tab, and you will see your test content listed. By opening one of the items, you can verify that your IRM Desktop is healthy and that you can authenticate to the IRM Server.

• BES and BES Express co-existance

  - by ITGuy24

  Question: Can I deploy BES and BES Express with Exchange 2010? Any tips for doing this if possible? Background: We have a lot of users with personal BlackBerry's and we would like to allow them to start using their devices for receviing corporate email. We don't need full BES features for these users, just the ability to enforce passwords and remotely wipe. Plus users have never wanted to upgrade their data plans to the more expensive BES plans. So BES Express is a great fit. We already have an existing BES, for corporate owned BB's. We want to keep this as is allows us to enforce several policies, not available on BES Express.

• Secure PHP environments with PHP-FPM and SFTP

  - by pdd

  I'd like to set up secure environments for a small number of untrusted PHP websites on a Debian server. Right now everything runs on the same Apache2 with mod_php5 and vsftpd for administrative file access, so there is room for improvement. The idea is to use nginx instead of apache, SFTP through OpenSSH instead of vsftpd and chrooted (in sshd_config), individual users for each website with their own pool of PHP processes. All these users and nginx are part of the same group. Now in theory I can set 700 permissions on all PHP scripts and 750 on static files that nginx has to serve up. Theoretically, if a website is compromised all the other users' data is safe, right? Are there better solutions that require less setup time and memory per website? Cheers

• Lock down a site using Forms Auth in IIS7 with Windows Auth

  - by justjoshingyou

  I have an ASP.NET MVC 1.0 application that uses Forms Authentication. We are using Windows Server 2008. I need to lock down the site so that only certain users (in AD Groups) can access the site. Unfortunately, though, when I set the site to not allow anon users and use windows authentication, due to the integration of the site and IIS, it shows the user as signed in as their domain account, instead of allowing them to sign in through Forms Auth. So, I need a mixed mode authentication. I need the site to be only accessible through windows auth, without anon users, but once you are in, it needs to use forms auth only. How would I go about doing this the right way?

• Can't assign software to non-admin account

  - by labyrinth

  I'm trying to deploy software on our domain using group policy, but I am only able to do so if the user is a member of a group with administrative privileges. We do not want to allow users to install programs generally, but do want to be able to assign/publish. The test program I'm using is originally a .msi file, and it installs fine for users in the administrators group. How can we assign/publish to normal users without opening up the ability to install whatever? Also, from what I've read, I believe I have correct permissions on the folder/share where the .msi files are stored. This is on Win2008R2 with Win7Pro clients.

• How to diagnose "Internet explorer cannot display the webpage"

  - by Colen

  Our web site is working great for 99.99% of our users, but a few people (all of whom use Internet Explorer) are running into an error. Most pages on the site load fine, but for one specific page (the same page for all affected users), all they get is: Internet explorer cannot display the webpage It doesn't matter whether the page is accessed over http or https - it fails to load either way. Every other page on the site, as far as I can tell, works fine for them. Not only that, the same users can load that specific page fine in Firefox. I've checked the web server logs and I can't find any smoking guns there. The site is running IIS on Windows Server 2003. Is there any way to get IE to give the user more information than just "cannot display the web page"? There's a "More information" button, but all it tells you is to make sure that your DNS servers are working, make sure you're not working offline, etc. :(

I have added the Allow_Cmnd /usr/sbin/userdel for sudo users but this does not delete all /tmp files associated with the user. So how shall I tweak the sudoers to allow them to delete certain files in /tmp directory only. I googled a bit but learned that regex may be be application at this. I tried couple of tweaks but its not working for me. I would like the users to have ability to execute command such as find /tmp -uid 10002 | grep joeuser | xargs rm -rf

• Exchange 2003 resource scheduling with mixed client versions

  - by Daniel Lucas

  We run Exchange 2003, but have a mix of Outlook 2003/2007/2010 in the environment. We have three rooms that need to be configured as resources. Some observations we've made with resource scheduling/booking are: Outlook 2010 users have trouble with the native Exchange 2003 resource scheduling method and require direct booking to be configured via registry Outlook 2007 users are unable to use direct booking (is this accurate?) Outlook 2003 users can only use the native Exchange 2003 resource scheduling method (is this accurate?) Direct booking cannot be combined with the auto-accept agent What is the correct way to setup resource scheduling in a mixed environment like this? Thanks, Daniel

• With Monit, how do I restart a process when a directory timestamp check fails?

• Hosting custom domains with IP address flexibility

  - by F21

  I am building a small service where users will be assigned a subdomain such as: myusername.myservice.com anotheruser.myservice.com I know that I can set up a wildcard vhost and using some configuration regex, serve the files like so: myusername.myservice.com ===> /var/www/myusername anotherusername.myservice.com ===> /var/www/anotherusername The problem is that I would like to allow users to alias their own domain names to their service. I understand that for the webserver, once the user adds the domain via my web interface, I can easily create a vhost for the domain in nginx and then refresh the webserver. The problem is that I would prefer to NOT let the users add an A record of my webserver's IP address as I would prefer to keep things flexible (when we upgrade our infrastructure to something more complex to scale). What is the best way to achieve this?

• Filezilla FTP Server - Security Implications of its usage on Windos Server 2003

  - by Brian Webster

  I'm running Filezilla server on my dedicated windows 2003 server. It uses its own user-access control system. The Filezilla server service itself is running under the System user. When I setup users within the FTP Server Administrator Interface, I do not need to setup equivalent users, or adjust permissions on folders to allow users to login. Example: I setup TestFTP user with password 'p' I set the home directoy of TestFTP user to be e:/website I verify that e:/website only has permission for the System and Admin accounts (right click - security in windows explorer) TestFTP is able to login to the server just fine. I'm OK with this (perhaps due to ignorance?). Is it generally frounded upon to utilize a FTP Server such as FileZilla Server that bypasses the built-in UAC in this method? If I wasn't clear enough, please let me know.

• IMAP can't access virtual account sharing name with local user account

  - by chernevik

  I am setting up a postfix/dovecot mail server with virtual accounts, per the Chris Haas tutorial. I'm finding that virtual users who also have local user accounts on the mail server cannot access their email remotely via IMAP. They're told they cannot login. (I'm using Thunderbird for that). These same users can login when emulating IMAP locally via telnet. Virtual users without local accounts have no trouble with IMAP access from remote clients. These local user accounts have vestiges of prior efforts in their home directories: mbox files, Mail and mail directories. I've looked at the logs for clues to where the remote login process is failing (dovecot authentication failure? confusion over where emails are stored?) but found nothing helpful. I haven't found much in the dovecot or postfix documentation that describes the IMAP login process and expectations in enough detail to help me diagnose this.
