• What does S in linux file properties mean?

  - by penguin

  I'm creating directories and changing the permissions of them in perl with the following code: umask 0000; mkdir $path, 0770; chown $userid, $groupid, $path; Now when I do ls -l on a directory I've just created, they are as follows: drwxrws--- 2 user group 4096 Nov 3 15:34 test1 I notice for the group permissions, there's an s instead of x. Even if I chmod manually to remove all permissions for the user and group ("chmod g=" and "chmod u=", it's still there: d-----S--- 2 user group 4096 Nov 3 15:36 test2 The internet suggests S means everything in the folder is run as su or something? I don't quite understand what it means but I figure I should understand seeing as these are webroots so if there's a security implication, I ought to be aware of it. Many thanks for your help!

• Mac OSX Server - Mac Mini to XServe Migration

  - by notpeter

  If I build out a Mac OSX Server install on a Mac Mini and then when it's ready for production I image the disks to an XServe, is there any reason the resulting system won't just work? Assuming I'm able to keep the same IP address are there any other issues I should be aware of? I'll be running minimal services, just AFP, SMB and Open Directory. TMI: My Intel XServe is full of cruft. Was originally a G4 XServe running 10.3, upgraded to 10.4 then migrated to 10.5 on the Intel XServe. I'd like a clean start, but can't spare the XServe downtime while I build out the install, can I just use a Mac Mini for dev and then switch to the XServe for production.

• Linux laptop encryption

  - by kaerast

  What are my options for encrypting the /home directories of my Ubuntu laptops? They are currently setup without any encryption and some have /home as a separate partition whilst others don't. Most of these laptops are single-user standalone laptops which are out on the road a lot. Is ecryptfs and the encrypted Private directory good enough or are there better, more secure, options? If somebody got hold of the laptop, how easy would it be for them to gain access to the encrypted files? Similar questions for encrypted lvm, truecrypt and any other solution I may not be aware of.

• DOMPDF generation error

  - by VDVLeon

  Hello, I have a big problem at my work. We had to make a page who displays a exercise for the users. But that page need also to be available as pdf. To do this we used DOMPDF. This worked perfectly on your development server but when we moved it to the production server dompdf generates pdf with errors. When i open the pdf i get the error from Adobe Reader: 110. The first server (development) was Debian. The production server runs CentOS 5. DOMPDF used PDFLib or CPDF, but both generate the same error. Does anybody know what kind of differents on the server i need to be aware of ?

• Advantages of multiple SQL Server files with a single RAID array

  - by Dr Giles M

  Originally posted on stack overflow, but re-worded. Imagine the scenario : For a database I have RAID arrays R: (MDF) T: (transaction log) and of course shared transparent usage of X: (tempDB). I've been reading around and get the impression that if you are using RAID then adding multiple SQL Server NDF files sitting on R: within a filegroup won't yeild any more improvements. Of course, adding another raid array S: and putting an NDF file on that would. However, being a reasonably savvy software person, it's not unthinkable to hypothesise that, even for smaller MDFs sitting on one RAID array that SQL Server will perform growth and locking operations (for writes) on the MDF, so adding NDFs to the filegroup even if they sat on R: would distribute the locking operations and growth operations allowing more throughput? Or does the time taken to reconstruct the data from distributed filegroups outweigh the benefits of reduced locking? I'm also aware that the behaviour and benefits may be different for tables/indeces/log. Is there a good site that distinguishes the benefits of multiple files when RAID is already in place?

• Meetings Disappearing from Outlook 2010 Public Calendar

  - by Neil

  We are experiencing a frustrating issue with our Public Calendars in Outlook 2010. Meetings that have been scheduled months in advance are missing, but will then reappear. If user A logs in @ 9:30 and goes to the calendar, certain meetings will be missing. 15 Minutes later, when user B logs in, the meetings are there. It is not tied to the actual user- I have seen this issue occur with the order of logging in reversed. These are with meetings that were posted to the calender months ago, so it should not be an issue of an item being updated. We have not upgraded our Exchange environment (still running on 2003), but this is a new machine, running Windows 7 Professional, on a domain, running office 2010. Are there any quirks or settings that I am missing or not aware of?

• What response should be made to a continued web-app crack attempt?

  - by Tchalvak

  I've issues with a continuous, concerted cracking attempt on a website (coded in php). The main problem is sql-injection attempts, running on a Debian server. A secondary effect of the problem is being spidered or repeatedly spammed with urls that, though a security hole has been closed, are still obviously related attempts to crack the site, and continue to add load to the site, and thus should be blocked. So what measures can I take to: A: Block known intruders/known attack machines (notably making themselves anonymous via botnet or relaying servers) to prevent their repeated, continuous, timed access from affecting the load of the site, and B: report & respond to the attack (I'm aware that the reporting to law enforcement is almost certainly futile, as may be reporting to the ip/machine where the attacks are originating, but other responses to take would be welcome).

• Mandatory Profiles on a Server 2003 TS Box

  - by Chloe

  I have a Windows Server 2003 box which will be acting as a terminal server. It will actually be running Citrix, but I don't believe that to be relevant here. There has been a request for every user to use a single mandatory profile. I've used mandatory profiles before, but there have been generally different profiles for different users so I've always used the "Terminal Services Profile" tab to good effect. What I'd like this time is a single setting, such as a Group Policy or similar that simply forces every non-domain admin user logging on to the box into using the mandatory profile. We'll be using Folder Redirection to take care of everything else. I'm aware of the following GPO: Computer Policy\Computer Configuration\Administrative Templates\Windows Components/Terminal Services Set path for TS Roaming Profiles But, as that's a computer policy, will it not apply to all users including administrators? If so, is it possible to exclude admins somehow?

• Moving Portable Office. Have a LAN & Phone line query?

  - by John Smith

  We are about to move a portable office that has 8 phones and 12 lan connections. They are all wired back to our main switch and Nortel bcm200 phone system which are only about 20m (65ft) away. After the move the office will be 180m (600ft) away from these. What is the maximum length of cable a digital phone line can be? I am aware that a lan connection can only be 100m (305ft) when using cat5e utp. Does this rule apply to phone connections also? If so how can I extend beyond 100m for the phones? I was going to install about three cabinets, 3 switches and 6 patch panels for the lan connections but the ideal struck me tonight that maybe I could run a fibre optic line. Would this be feasible? Any feedback on this is greatly appreciated. Thanks

• How do I mount a harddrive to my /home folder in OS X?

  - by Joachim Hedberg

  Im wondering how to mount my second HDD to my /home folder like you do in other *NIX systems, making the mount point just that folder and not a standard HDD. I am aware of the method of copying my /home folder and then telling OSX via System Preferences/Users & Groups to look for the folder in a different location. What I am wondering is if there is a way to properly mount the entire HDD to become nothing more than my /home. I don't want it to even show up in Finder as an HDD. Is this even possible?

• A PDF viewer for large margins in fullscreen

  - by jmn

  I am looking for a way to pleasantly read PDF files on my widescreen (22" 1680x1050) monitor. My problem with all pdf the PDF-viewer applications I have tried is that they do not handle wide and high margins well. If I go to fullscreen mode in my viewer and zoom in so that the extra margins are cropped, I can view the pages nicely, the annoyance however is that I have to reposition the pages every time I navigate to another page. I am sure there must be a way to make a PDF viewer that can solve this problem and perhaps there is one you know of? I am aware of something called PDF Reflow in Acrobat Reader but that only works with certain specific (tagged) files. I want a PDF viewer with a smarter zoom/next page function or an automatic margin-crop function. Is there such a thing?

• (Free?) Hosting Control Panels

  - by Alix Axel

  I've installed and used both cPanel and Plesk on my dedicated servers in the past and I truly enjoyed the features and simplicity of cPanel (specially the auto-update feature in WHM), recently (a couple of months ago) I also tried a beta version of the open-source OpenPanel and although it looks really nice I found it kinda limited in terms of features, such as automatic system updates, automatic backups and the ability to add addicional hosts to the MySQL allowed clients list - just to name a few. Besides OpenPanel, I'm aware of Usermin, Webmin, Virtualmin, ISPConfig, VHCS, web-cp and FlexCP - although I've never had the opportunity to try any of them before... Are you familiar and recommend any of these? It's been a while since I managed a dedicated server and I'm wondering what would be a good hosting control panel for me, preferably a free / open-source one that has similar features / usability of cPanel. I appreciate all input, thanks! =)

• Ubuntu issues when moving hard disk to new system

  - by Tim

  I'm working on a legacy project with a small single board computer running Ubuntu 10.04 on a compact flash card. I need to be able to save away a working image (via dd) and copy said image to other compact flash cards for use in other single board computers (with identical hardware) I'm able to copy the image to other flash cards and bootup on other systems no problem. But I'm seeing strange behavior. For instance, I can't use sudo on the new system (“sudo: must be setuid root”). I've gone down the path of trying to fix this, but have run into a slew of other issues. General question is: what do I need to be aware of when moving a hard disk containing Ubuntu (in my case a compact flash card) to another computer? I was hoping it would be seamless to Ubuntu since it's moving to a system with identical hardware. Is there something that needs to be done to make it "portable"?

• Are there website monitoring services that can monitor HTTP file download times?

  - by Mark

  The software company I work for would like to monitor how long it takes to download their installers (hosted in several locations and about 30-100mb each) from various countries around the world. I am aware of website monitoring services like Pingdom and Site24x7, and have contacted their customer services, but neither have the facility to monitor download times of such large files via HTTP. For various reasons, we are not able to rely on weblogs. Does anyone know of any third-party services that could help us? Many thanks.

• Is using Capistrano for user maintenance tasks on university lab feasible?

  - by danielkza

  I've been looking around for tools to replace some legacy scripts for creating and maintaining accounts in a university computer lab ecosystem consisting of things like: LDAP and Kerberos for authentication User home storage and web pages Entries on an SQL database Printing quotas Mailing lists, etc. I'd also like to automate machine and VM membership for Kerberos and Puppet if possiible. I've found Capistrano, and while the basic principle of running tasks on remote hosts through SSH seems to fit, and the DSL in Ruby looks quite nice, I've found most documentation is related to application deployment, not generic tasks. I'm also not aware of any good way to parameterize tasks so I can pass on the user information for creation. Is something about Capistrano I am missing, or is it not the correct tool for this job? Are there any more userful alternatives?

• How do I disable Tomcat? [closed]

  - by Dave King Popeye Mason

  Possible Duplicate: How to disable Tomcat on linux? According to my server host, something called Tomcat is hogging all my resources and slowing down the server. As far as I'm aware I'm not using it as the only thing running on the server is Plesk and a few Wordpress installations. I'm a real dummy at using SSH, I can navigate to folders, change permissions and that's about it. Could somebody explain to me as if I'm a 5 year old how to disable TomCat (and also how to stop it re-enabling on startup)? Thanks!

• How many times can data be read from a USB flash drive?

  - by John

  While I am aware that performing writes on a USB flash drive degrades the life expectancy of the device. I have heard the quantity of writes is anywhere from 100 thousand to 10 million, but I have not heard about number of read operations. Does reading from the device count toward this total? I am interested in writing only once to a flash drive and setting it to read-only. Then reading files from the device a thousand or more times per day, but am wondering if (at say 1,000 reads per day), the flash drive will need to be replaced within 100 days (assuming a 100,000 r/w cycle lifetime)?

• Screenshot shows black area with dual monitors on Ubuntu

  - by Hollister

  When using the built-in window screenshot function on Ubuntu (alt-printscreen) with dual monitors, a black rectangle covers about the top third of the captured window (or that area is not captured). When capturing the entire screen (printscreen), the left monitor shows the same size rectangle, but it doesn't cover the window, but pushes it down. It's as if the capture is using the smaller monitor's dimensions, and is not aware of the larger monitor. Here are the images: Window capture: http://moby.to/8d69hp Screen capture: http://moby.to/v99gqs When using the command line, I get this error: $ gnome-screenshot --window (gnome-screenshot:8522): GdkPixbuf-CRITICAL **: gdk_pixbuf_composite: assertion `dest_y >= 0 && dest_y + dest_height <= dest->height' failed System info: Ubuntu 10.04.2 LTS (Lucid) Linux 2.6.32-32-generic Left monitor (laptop) 1280x800 Right monitor (external) 1920x1080 Is there a way to get this to work? Edit: this does not happen with one monitor or when the monitors are mirrored.

• Mono on Linux: Apache or Nginx

  - by Furism

  Hi, I'm developing an ASP.NET application that will be run under Linux/Mono for various reasons (mostly to stay away from IIS, quite frankly). Of course the first web server I had in mind was Apache. But Apache, for all its advantages, adds a lot of overhead. Also, the application I'm building needs to be highly scalable and performance is one of the main concern. Apache has, obviously, a very good reputation and its record speaks for itself, but I don't need things like Reverse Proxy or Load Balancing because dedicated network devices would be used for that. So those modules from Apache will never be used. So basically my question is: since Nginx seems to fit exactly needs, is there any caveat I should be aware of? For instance, is Nginx renowned to be particularity safe? When security flaws are detected, how fast are they patched? Any insight on the pros and cons of using either of those servers in conjunction with Mono is welcome.

• Options to optimize lotus notes 8.5.X

  - by Jakub

  Has anyone found actually useful optimization methods for the bulky, fat, eclipse giant, nuissance that is Lotus Notes 8.5? I want it to be fast, and not eat up system resources like crazy while I run it ALL day (as it is my company's corporate mail / cal / scheduling solution). I've tried various hacks for the JVM heap size (if I recall correctly). None really bring a performance improvement. I have a dual core cpu, if that helps (I tried going the route of optimizing JAVA for 2 cores in hopes it would work, but seen no speed improvement). Notes is just sooo bloated, anyone have any suggestions to optimize/mod this thing so it is more responsive and less of a resource hog. Note: I don't want to switch to the web version, or the standard stripped down versions, I am aware of those, I just cannot since we don't run those internally for the company.

• Mutli-processor workstation as a workstation/server

  - by posdef

  I work in a research institute and a number of programs we use are computationally intensive (I actually wrote one of them). Right now we have one computer that is dedicated for one of these programs (with local accounts only, as in users physically sitting in front of that pc) and the other programs are run on individual workstations assigned to people. I have been looking around to common brands such as Dell and HP, for a some sort of a small/medium scale server, which can be used as a workhorse by sending tasks remotely. It appears as if there is nothing in between workstations with one 6-core processor and a bunch of extras (like fancy graphics etc) and rack mount servers with ridiculous amount of RAM and HDD expansion capabilities but still relatively little number of processors/cores. I wonder if what I am looking for is such a small niche product? Are there other solutions that I might not be aware of? Does anyone know of a multi proc- multi-core workstation/server that is still within the reasonable

• How to bind Apache to specific IP and port on Windows Server 2008

  - by webworm

  I have a Windows Server 2008 R2 that I use to host various ASP.NET applications under IIS7. I would also like to run various PHP based web apps using Apache (or Apache 2). The server has three static IP addresses assigned to it and I would like to bind one of the IP addresses to Apache while using the other two IP addresses for IIS. I can use the IIS Manager to bind the specific IP addresses to IIS, but I am unaware of how to do this with Apache. Can anyone tell me how to go about binding Apache to a specific IP address and port (port 80 is what I want to use). Please note .. I am aware that PHP can run under IIS. In fact that is how I have been running my PHP web applications. However, there are so many inconsistencies and pitfalls with PHP running under IIS that I just prefer to use Apache.

• Auto-hide OS X menu bar?

  - by dbr

  Is there a way to auto-hide the OS X menu bar, like is possible with the Dock? There was an application "Menufela" that did this for Tiger, but I'm not aware of anything similar for Leopard/Snow Leopard.. I'm almost certain this is (programatically) doable, because in full-screen applications the menu bar is hidden, and reappears when you mouse the mouse is at the top of the screen.. Edit: With the help of Steve Folly's answer, the following code: [[NSApplication sharedApplication] setPresentationOptions: NSApplicationPresentationAutoHideMenuBar | NSApplicationPresentationAutoHideDock]; ..will auto-hide the menubar (and the dock, as mandated by the API), but only for the current application: When controlling or disabling features of Mac OS X system using SetSystemUIMode the requested behaviors are only in effect while the process which called SetSystemUIMode is frontmost ..close, but not quite there
