• Dropbox context menu missing in OS X

  - by slhck

  Problem My Dropbox context menu is missing in OS X Snow Leopard (10.6.8). While the Dropbox service runs normally, Finder doesn't show the icons and also doesn't give me the ability to browse files on the website or copy the public link. What I've tried Removed ~/.dropbox and ~/Dropbox/.dropbox.cache Reinstalled Dropbox.app (both 1.4.7 stable and 1.5.0 experimental), went through the setup again Restarted Finder Logged out and back in All of these I've done over and over again, in random permutations. I've made sure that Dropbox appears in the Login Items under my Account (and I've never touched that) I don't know if ~/Library/Contextual Menu Items is missing the Dropbox plugin or if there shouldn't be one after all. In any case, I can't get the icons or the menu to appear.

• Deleting slow on X11 emacs

  - by Malvolio

  I'm running GNU Emacs 21.4.1 on a (remote) remote Linux ((CentOS) box, using my MacBook as the X-server. Works fine, unless I try to delete a word, line, or region. Then it locks up for 30 seconds or so. It sounds like a minor thing, but you realize how often you do a delete when you have to stop for 30 seconds every time. My theory is that Emacs is trying to put the text in the X-server cut-and-paste buffer, which is trying to put it in the OSX cut-and-paste buffer and somewhere along the way, the process is blocked until it times out. (My only evidence for this theory is (a) copy-region behaves the same way and (b) deleted text doesn't show up in the buffer.) Any suggestions appreciated. Edit: (setq interprogram-cut-function nil) fixed me right up. Which makes perfect sense. Thanks, Trey.

• Replicate portion of an LDAP directory to external server

  - by colemanm

  We're in the process of setting up a Jabber server on Amazon EC2 right now, and we'd like to have our internal users authenticate via LDAP so we don't have to create/manage a separate set of user accounts than the master directory in the office. My question is: is there a way to copy, unidirectionally, a segment of our internal LDAP directory (the user accounts OU) to an external LDAP server and authenticate Jabber against that? We're trying to work around having our externally hosted machines out in the cloud accessing our internal network directly... If we can replicate in one direction only a subset of the user accounts, then if that gets compromised we don't necessarily have a critical security breach into our internal network.

• Checking version of Applications installed in ~/Applications with unknown username

  - by ridogi

  I'd like to check the version of Firefox through Apple Remote Desktop of all managed computers. I have written this, but it only checks for Firefox in /Applications /bin/cat /Applications/Firefox.app/Contents/Info.plist | grep -A 1 CFBundleShortVersionString | grep string | sed 's/[/]//' | sed 's/<string>//g' For standard users Firefox auto update breaks if it is in /Applications so I instead have it installed in ~/Applications I'd like to check that copy (if it exists), but I can't specify the path in the command since it is unique to each computer. For example: /Users/jon/Applications/Firefox.app /Users/arya/Applications/Firefox.app Presumably I want to use find and pipe the result to my command. This should work for 10.6 through 10.8

• Speeding Up Search On Ubuntu File Server Accessed Through Windows

  - by John Birdy

  I run an Ubuntu box as a media server, which I use to either share files (copy and paste off of the network drive), or stream to my computer (which runs Win7), or to my xbox. I have a lot of files on there, especially music. Currently when I'm searching for a file, I just use Windows' search, which can be quite slow. I was wondering if there were better ways to search from my Windows box? I'd prefer not to SSH in to the box and use find or something like that. Is there any way to speed up Windows' search? Or an easy alternative? Thanks!

• Why does VNC eat certain characters?

  - by TK Kocheran

  I often use VNC to connect to my desktop upstairs using a laptop downstairs over my home network. I tunnel the VNC connection via SSH. The problem I keep running into is that I'll attempt to type a ! or a : or even a captial A and it will come across the wire as a 1, ;, or a respectively. Is this something I can fix? It's really REALLY annoying while one is programming to have to pop open character map and find a colon and copy/paste it in each time. Running Ubuntu 10.04 upstairs, Linux Mint 10 downstairs.

• Duplicating keepass files instead of creating a new file

  - by BlakBat

  I'm currently using KeePass 2 and syncing them via dropbox. I have a few KeePass files (one for websites, one to store software licenses, etc...) Every time I need a new KeePass file, I just create a copy of the kbdx file, open it, remove all existing entries, change the key transformation rounds to another pseudo-random value. I do not change the master password. I want to know if this was unsafe practice, or was a security risk, compared to just creating a new KeePass file via the "File-New" menu. The reason I don't use the menu: i'm lazy enough to not want to reconfigure "database settings" every time.

• Why can't mplayer/libdvdcss/whatever play my DVDs?

  - by che

  To put it bluntly, mplayer is unable to correctly play video DVDs. It seems to correctly find the title and everything, but the picture is broken or not displayed at all, with messages like: a52: CRC check failed! a52: error at resampling [mpeg1video @ 0xa8d840]sequence header damaged [mpeg1video @ 0xa8d840]Missing picture start code Now, this all is on amd64 Gentoo Linux system. I believe the problem is not in mplayer itself, since the playback also breaks in VLC or when i copy the VOBs via vobcopy and try to play them afterwards. I use libdvdcss-1.2.10 and libdvdread-4.1.3_p1168 (current stable in Gentoo), and tried previous versions of both libs, but it didn't change a thing. The DVDs I have tried play fine in regular DVD player or on a Windows laptop. I remember the playback used to work about a year ago and I don't know what to try next. Any hints would be welcome.

• Backup XAMPP (Htdocs & MySQL)

  - by Max

  I have a development server, but would like to backup everything at least daily to a remote location. I would like to backup the htdocs folder and the MySQL servers. But if possible also the settings of the server and anything else relevant. At the moment I am using DropBox for the htdocs, but this is not ideal. I have looked into Git, DropBox simple copy paste on a daily basis. I was wondering what any advice would be. For example how hard would it be to set it up as a cloud based system? Any and all advice is greatly appreciated.

• chroot for unsecure programs execution

  - by attwad

  Hi, I have never set-up a chroot-jailed environment before and I am afraid I need some help to do it well. To explain shortly what this is all about: I have a webserver to which users send python scripts to process various files that are stored on the server (the system is for Research purpose). Everyday a cron job starts the execution of the uploaded scripts via a command of this kind: /usr/bin/python script_file.py All of this is really insecure and I would like to create a jail in which I would copy the necessary files (uploaded scripts, files to process, python binary and dependencies). I already looked at various utilities to create jails but none of them seemed up-to-date or were lacking solid documentation (ie. the links proposed in How can I run an untrusted python script) Could anyone guide me to a viable solution to my problem? like a working example of a script that creates a jail, put some files in it and executes a python script? Thank you very much.

• Why not install Msvcr71.dll into system32?

  - by hillu

  While looking for an authoritative source for the missing Msvcr71.dll that is needed by a few old applications, I stumbled across the MSDN article Redistribution of the shared C runtime component in Visual C++. The advice given to developers is to drop the DLL into the application's directory instead of system32 since DLLs in this directory are considered before the system paths. What can/will go wrong if I (as an administrator, not a developer) decide to take the lazy path and install Msvcr71.dll (and Msvcp71.dll while I'm at it) into the system32 directory (of 32 bit Windows XP or Windows 7 systems) instead of putting a copy in each application's directory? Is there another good solution to provide the applications with the needed DLLs that doesn't involve copying stuff to the application directories? added after first answers: I understand that incompatible API changes may have been made to the mentioned DLLs, but pretty much every mention of incompatibilities I have found using Google had to do with games or video codecs. Right now, I expect that the risk of breakage is pretty small. Am I missing something?

• Sudden slow read & write speed on all IO

  - by user23392

  I have a custom built rig that has 2 storage drives. for OS: Western Digital 1.0TB HARD DR 64MB for other stuff: Corsair Performance 3 128GB (SSD) [ expected read speed: 400 mb/s ] The system was incredibly fast for a couple of months, then one day i was playing a game then it started to get buggy (some sounds and objects disappearing), i stopped the game and the system seemed to be unstable so i had to shut it down, next morning i couldn't start it up, it was saying something about corrupt device. I formatted both disks and installed a fresh copy of windows, all i can say that since that day the system was never like before, it takes 10 minutes to boot up (the icons and desktop slowly appear). but once it's done the slowness isn't as noticeable. Here's my benchmark on the HDD ( read speed - write speed ): And the SSD: Anyone knows what could be the issue?

• Life Cycle Navigator?

  - by C.W.Holeman II

  In many environments the file system directory structure and naming conventions attempt to allow one to use a file manager to navigate the life cycle of a document. This overloading of functions makes it difficult for users to handle the complexity. A file browser is a tool that lets the user navigate among files located in a directory structure to find a specific file. Whereas, when given a specific file, a life cycle navigator is a tool that lets the user navigate its life cycle from source to published copy and across versions. Does a Life Cycle Navigator exit? I see a user pointing at an object: Left mouse button displays the document Right mouse button has a Life Cycle Navigator (LCN) The LCN displays a tree for a specific document within a file manger, for example: Published 3.2 Current 3.1 3.0 +2.x +1.x +Archived +All Source Draft 3.2 Current 3.1 3.0 +2.x +1.x +Archived +All +Work Flow +Properties Or from a command line: $ lcn x.pdf --open_source_document | my_favorite_editor $ lcn x.pdf --show_published_version_info $ lcn x.pdf --show_previous_publish_versions_info See also, Life Cycle Navigator.

• Repartition hard drive using Mac OS X, keep existing data

  - by Jonny

  I got a 1 TB disk a year or so ago and loaded it with some hundred of GB of data. I somehow neglected to check the file system, which turns out to be FAT-32 and thus too small for files bigger than 4 GB. So now I want to change it, without deleting the data. I thought I'd just make a new partition in the so far unused space. Then with the new partition, copy/move the data into the new partition, and then delete the old FAT-32 partition, and make the new partition bigger again... or just make a few more partitions. The critical step here is, can I make that new partition without ruining the data? The data should be fairly sequentially added to the start of the disk, but what do I know... so that's why I'm asking. Can I safely use Disk Utility for this? Any recommended file system?

• Postgres backup

  - by Abbass

  Hello, I have a Bacula script that does an automatic backup of a Postgres Database. The script makes two backups using (pg_dump) of the data base : The schema only and the data only. /usr/bin/pg_dump --format=c -s $dbname --file=$DUMPDIR/$dbname.schema.dump /usr/bin/pg_dump --format=c -a $dbname --file=$DUMPDIR/$dbname.data.dump The problem is that I can't figure out how to restore it with pg_restore. Do I need to create the database and the users before then restore the schema and finally the data. I did the following : pg_restore --format=c -s -C -d template1 xxx.schema.dump pg_restore --format=c -a -d xxx xxx.data.dump This first restore creates the database with emtpy tables but the second gives many error like this one : pg_restore: [archiver (db)] COPY failed: ERROR: insert or update on table "Table1" violates foreign key constraint "fkf6977a478dd41734" DETAIL: Key (contentid)=(1474566) is not present in table "Table23". Any ideas?

• Web server replica not working in other server

  - by user761076

  I have a Drupal installation (php+mysql) in a server, and I'm trying to copy this installation to another server with the same configuration, same physical and virtual path, same db configuration, etc. The thing is, in my new server I get the homepage to work, but not the inner pages, so I guess has something to do with rewrite (mod_rewrite is installed) (both .htaccess are the same). When I access http://localhost/myweb/content/mypage I get a 404 or a "Forbidden" if I uncomment this in httpd.conf (original httpd.conf does not have this entry): <Directory path/to/docs"> DirectoryIndex index.php index.html Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> Any clue? Thank you

• Select firefox search result

  - by Nicolas C.

  I am working on a daily basis on a web application with very large menus. Also doing lots of other Excel manipulations, copy and pasting, etc., I am quite fond of keyboard shortcuts as much faster than using the mouse to point, double-click and then going back to my keyboard etc. Hence, my question is quite simple, does anyone know if there is any shortcut under Firefox which would let me actually select (and not highlight) in my web page the search result so that I can for instance do the following manipulation sequence? [Ctrl]+[F] type the search string, for instance 'regional_unit' the missing shortcut to actually select in my page the string which is currently highlighted thanks to the search feature of FF [Space] or [Enter] key to activate the web element which in my case would systematically correspond to a link or button, etc. May be there would be an addon replacing the default search feature, I don't know... I tried to look over the internet but with the words I am using for this investigation, I do not get relevant search results under Google :(. Thanks a lot

• Is it safe to expect Sun Java 6 to supported for the life of RHEL 6?

  - by Ophidian

  I'm in the planning stages of a java application that we're targeting for Red Hat Enterprise Linux 6. Unfortunately, we're stuck at RHEL 6.1 which does not ship the java-1.7.0-oracle package set (they were added in 6.3) and I don't really have any control over when we will be upgraded to the more recent version. I don't have any specific technical requirements to use Java 7, but Java 6 is going to hit public EOL in February 2013. Am I safe to assume that since Red Hat (and subsequently Oracle with its Oracle Unbreakable Linux) has shipped a copy of Java 6 in the java-1.6.0-sun package, it will support it for the entire 10 year support life of RHEL6?

• Downloading a repository for local use

  - by EBV2010

  I'm trying to get Thunderbird working in such a way that it will properly work with Kolab groupware. For that I need it to be in a fixed setup of Thunderbird and add-ons (Lightning, SyncKolab) without automatic updates and I need to present version of Thunderbird to be available for the users. What I hope to achieve is that the repository for Thunderbird as it is now on http://ppa.launchpad.net/mozillateam/thunderbird-stable/ will be available on my local server so I always use that version even if Thunderbird goes to a new stable version. What I hope to achieve is this: - I copy the content of http://ppa.launchpad.net/mozillateam/thunderbird-stable/ to my server - I make it available as a repository on my network I neither know if this is possible or allowed under the license etc.

• Logical move of a server to UK, what do I do with the SSL certificates

  - by flyfishr64

  I have been asked to move a rails application from the US to the UK. This involves bringing up the rails stack on Ubuntu 8.04.4; that's completed. I'm stumped with the SSL configuration though. The plan was to bring this server up with the same domain name but temporarily use a subdomain (app2.xxx.com instead of app.xxx.com) during the move and for testing, then rename it to app.xxx.com when we're ready for the cutover (does that make sense?). In the meantime, we need a new cert for the app2 subdomain. So to generate a CSR, I need a server key but do I need a new one, or should I copy the one from the existing production server?

• How to adjust a single side of rectangular selection made with Marquee Tool?

  - by Alex

  I am struggling to make a selection made of different layers. For example, a button with text and shadow (each in its own layer). I would like to copy it to a image file but it is really hard to select the shadow with a pixel precision. I do not know how to perform such task properly so I use Marquee Tool. However, it is hard to get all 4 sides right from the first attempt. What's worse, I could not find a method to adjust a single side of a selection made by Marquee Tool. Anyone may help what I am doing wrong?

• Problem with running a program from flashdrive

  - by rajivpradeep

  I have a USB drive with two partitions in it, one hidden and one normal. I have an application which swaps the memory and runs the flash application in hidden zone. The problem is that the application works fine on Windows 7 and when run on Win XP, it swaps the partitions but doesn't run the flash applications but just keeps running in the background. I can see it in task manager. But, when I copy the application to desktop and run, it runs with no glitch. I was facing the same problem on Win 7 too, but it was running as required when I ran it using "Run in XP mode" and then I applied a SHIM and is running since then as required. The application is built using VC++ 2008. What might be the problem?

• Is it possible to put only the boot partition on a usb stick?

  - by Steve V.

  I've been looking at system encryption with ArchLinux and i think I have it pretty much figured out but I have a question about the /boot partition. Once the system is booted up is it possible to unmount the /boot partition and allow the system to continue to run? My thought was to install /boot to a USB stick since it can't be left encrypted and then boot from the USB stick which would boot up the encrypted hard disk. Then I can take the USB key out and just use the system as normal. The reason I want to do this is because if an attacker was able to get physical access to the machine they could modify the /boot partition with a keystroke logger and steal the key and if they already had a copy of the encrypted data they could just sit back and wait for the key. I guess I could come up with a system of verifying that the boot has been untouched at each startup. Has this been done before? Any guidance for implementing it on my own?
