  • Fedora 17 - Can't access remote machine using hostname

    - by Aaron
    I am using Fedora 17 and am trying to access a remote machine (running Fedora 15) using its hostname which isn't working. The machine is right next to me on the same switch as my machine (so they are both on the same network with the same subnet and everything). When I was running Windows (7 32-bit) on my machine I could access the other machine no problem but now that I am running Fedora 17 that's not the case. Is there an additional daemon or something that I need to be using in order for this to work?

  • Mac OS X bug: Desktop & Screen Saver: image alignment preference is ignored.

    - by Aaron F.
    I have my desktop background set to rotate through a folder of images. Even though I have the alignment drop-down list set to "Center", the images still render as "Fill to Screen". When I change the list value to something else, then back to "Center", OR I manually click on a different image to display, well, that image is rendered as "Center". But all images that follow (via the "Change picture every x minutes" checkbox) are rendered as Fill to Screen. Any fix to this bug?

  • CalDav web application

    - by aaron
    Is there an open-source web app for viewing .ics calendars? I have a server running the open source CalDAV server "DAViCal" to share calendars between co-workers. I (the admin) add/delete the calendars by configuring my Mac OS X iCal application, but I want to also host a web app that displays a human-readable calendar, so without any configuration my coworkers can visit a web page and see the calendar. Thanks

  • Exchange\AD Authentication Using Alternate Email Domain

    - by Aaron Wurthmann
    I did this once. I can't recall how to do it anymore AND/OR it works differently in Windows 2008 than it did in Windows 2003. I recall it being an Exchange hosting feature. I would like users to login with their email addresses instead of only with their domain name. EXAMPLE: User: John Doe User logon name: [email protected] User logon name (pre-Windows 2000): DOMAIN\jdoe E-mail: [email protected] I would like for jdoe to be able to login as [email protected]

  • Computer wont POST after power outage

    - by aaron
    I had just turned my computer on and windows was loading when the power in my neighborhood went out. Normally, when I turn my computer on, the video card fan spins up, then slows down, POST and windows boots. Now, after the blackout, the video card fan spins fast and wont stop. Nothing is displayed on the monitor. The monitor does not detect that the video card is sending it signals, it just stays on standby. No POST or beep codes. This is what I have tried so far: My motherboard has 2 PCI express slots and I tried plugging the video card into both of them but that didn't fix anything. I have replaced the power supply, that didn't fix anything. I cleared the CMOS, that didn't fix anything. Does anyone have any idea of what could be wrong? Thanks!

  • BASH Wildcard Expansion

    - by Aaron Copley
    I'm not really sure how to phrase this, and maybe that's why I can't find any thing, but I want to reuse the values enumerated by a wildcard in a command. Is this possible? Scenario: $ ls /dir 1 2 3 Contents of /dir are directories 1, 2, and 3. $ cp /dir/*/file . Results in file being copied from /dir/1 /dir/2 and /dir/3 to here. What I would like to do is copy the files to a new destination name based on the wildcard expansion. $ cp /dir/*/file ???-file Would result in /dir/*/file being copied to 1-file, 2-file, and 3-file. What I can't figured out is the ??? portion to tell BASH I want to use the wildcard expanded values. Using the wildcard in the target nets a cp error: cp: target `*-file' is not a directory. Is there something else in bash that can be used here? The find command has {} to use with -exec which is similar to what I am looking for above.

  • Debootstrap Ubuntu over NFS leads to mknod I/O error

    - by Aaron B. Russell
    Hi everyone, I'm trying to prepare an Ubuntu environment for a diskless machine that will PXE boot and mount an NFS share as it's root. I've currently got another Ubuntu machine mounting the NFS share and I'm trying to debootstrap into it, but it has trouble creating devices over NFS: root@kimiko:~# mount | grep Seiuchi 192.168.0.203:/mnt/user/Seiuchi on /mnt type nfs (rw,addr=192.168.0.203) root@kimiko:~# debootstrap --arch i386 maverick /mnt http://gb.archive.ubuntu.com/ubuntu/ mknod: `/mnt/test-dev-null': Input/output error E: Cannot install into target '/mnt' mounted with noexec or nodev My NFS rule on the unRAID server is 192.168.0.201/32(rw,no_root_squash,sync). I don't have the noexec or nodev options set. I've not got much experience with NFS, so I'm probably missing something basic in the way I'm sharing this, but my attempts at Googling for an answer isn't really turning anything useful up. Does anyone have suggestions on what I might have missed or maybe relevant docs? Edit: Creating normal files (and directories) works just fine, I just can't create devices... root@kimiko:/mnt# mkdir foo root@kimiko:/mnt# cd foo root@kimiko:/mnt/foo# touch bar root@kimiko:/mnt/foo# mknod quux c 4 64 mknod: `quux': Input/output error root@kimiko:/mnt/foo# ls bar

  • SQL Server v.Next (Denali) : Another SSMS bug that should be fixed

    - by AaronBertrand
    Sorry to call this out in a separate post (I talked about a bunch of SSMS Connect items the other day), but Aaron Nelson ( blog | twitter ) jogged my memory today about an issue that has gone unfixed for years: the custom coloring for Registered Servers is neither consistent nor global. For one of my servers, I've chosen a red color to show in the status bar. Let's pretend this is a production server, and I want the red to remind me to use caution. I can set this up by right-clicking a Registered...(read more)

  • Portable scripting language for a multi-server admin?

    - by Aaron
    Please Note: Portable as in portableapps.com, not the traditional definition. Originally posted on stackoverflow.com, asking here at another user's suggestion. I'm a DBA and sysadmin, mostly for Windows machines running SQL Server. I'm looking for a programming/scripting language for Windows that doesn't require Admin access or an installer, needing no install process other than expanding it into a folder. My intent is to have a language for automation on which I can standardize. Up to this point, I've been using a combination of batch files and Unix shell, using sh.exe from UnxUtils but it's far from a perfect solution. I've evaluated a handful of options, all of them have at least one serious shortcoming or another. I have a strong preference for something open source or dual license, but I'm more interested in finding the right tool than anything else. Not interested that anything that relies on Cygwin or Java, but at this point I'd be fine with something that needs .NET. Requirements: Manageable footprint (1-100 files, under 30 MB installed) Run on Windows XP and Server (2003+) No installer (exe, msi) Works with external pipes, processes, and files Support for MS SQL Server or ODBC connections Bonus Points: Open Source FFI for calling functions in native DLLs GUI support (native or gtk, wx, fltk, etc) Linux, AIX, and/or OS X support Dynamic, object oriented and/or functional, interpreted or bytecode compiled; interactive development Able to package or compile scripts into executables So far I've tried: Ruby: 148 MB on disk, 23000 files Portable Python: 54 MB on disk, 2800 files Strawberry Perl: 123 MB on disk, 3600 files REBOL: Great, except closed source and no MSSQL or ODBC in free version Squeak Smalltalk: Great, except poor support for scripting ---- cut: points of clarification ---- Why all the limitations? I realize some of my criteria seem arbitrarily confining. It's primarily a product my environment. I work as a SQL Server DBA and backup Unix admin at a division of a large company. In addition to near a hundred boxes running some version or another of SQL Server on Windows, I also support the SQL Server Express Edition installs on over a thousand machines in the field. Because of our security policies, I don't login rights on every machine. Often enough, an issue comes up and I'm given local Admin for some period of time. Often enough, it's some box I've never touched and don't have my own environment setup yet. I may have temporary admin rights on the box, but I'm not the admin for the machine- I'm just the DBA. I've no interest in stepping on the toes of the Windows admins, nor do I want to take over any of their duties. If I bring up "installing" something, suddenly it becomes a matter of interest for Production Control and the Windows admins; if I'm copying up a script, no one minds. The distinction may not mean much to the readers, but if someone gets the wrong idea I've suddenly got a long wait and significant overhead before I can get the tool installed and get the problem solved. That's why I want something that can be copied and run in the manner of a portable app. What about the small footprint? My company has three divisions, each in a different geographical location, and one of them is a new acquisition. We have different production control/security policies in each division. I support our MSSQL databases in all three divisions. The field machines are spread around the US, sometimes connecting to the VPN over very slow links. Installing Ruby \using psexec has taken a long time over these connections. In these instances, the bigger time waster seems to be archives with thousands and thousands of files rather than their sheer size. You could say I'm spoiled by Unix, where the admins usually have at least some modern scripting language installed; I'd use PowerShell, but I don't know it well and more importantly it isn't everywhere I need to work. It's a regular occurrence that I need to write, deploy and execute some script on short notice on some machine I've never on which logged in. Since having Ruby or something similar installed on every machine I'll ever need to touch is effectively impossible because of the approvals, time and and Windows admin labor needed I makes more sense find a solution that allows me to work on my own terms.

  • Compressing and copying large files on Windows Server?

    - by Aaron
    I've been having a hard time copying large database backups from the database server to a test box at another site. I'm open to any ideas that would help me get this database moved without having to resort to a USB hard drive and the mail. The database server is running Windows Server 2003 R2 Enterprise, 16 GB of RAM and two quad-core 3.0 GHz Xeon X5450s. Files are SQL Server 2005 backup files between 100 GB and 250 GB. The pipe is not the fastest and SQL Server backup files typically compress down to 10-40% of the original, so it made sense to me to compress the files first. I've tried a number of methods, including: gzip 1.2.4 (UnxUtils) and 1.3.12 (GnuWin) bzip2 1.0.1 (UnxUtils) and 1.0.5 (Cygwin) WinRAR 3.90 7-Zip 4.65 (7za.exe) I've attempted to use WinRAR and 7-Zip options for splitting into multiple segments. 7za.exe has worked well for me for database backups on another server, which has ~50 GB backups. I've also tried splitting the .BAK file first with various utilities and compressing the resulting segments. No joy with that approach either- no matter the tool I've tried, it ends up butting against the size of the file. Especially frustrating is that I've transferred files of similar size on Unix boxes without problems using rsync+ssh. Installing an SSH server is not an option for the situation I'm in, unfortunately. For example, this is how 7-Zip dies: H:\dbatmp>7za.exe a -t7z -v250m -mx3 h:\dbatmp\zip\db-20100419_1228.7z h:\dbatmp\db-20100419_1228.bak 7-Zip (A) 4.65 Copyright (c) 1999-2009 Igor Pavlov 2009-02-03 Scanning Creating archive h:\dbatmp\zip\db-20100419_1228.7z Compressing db-20100419_1228.bak System error: Unspecified error

  • No architecture vs architecture-specific binaries

    - by Aaron
    From what I understand, the noarch suffix means that it's architecture independent and should work universally. If this is the case, why should I install architecture-specific packages at all? Why not just go straight for the noarch? Are there optimizations in the x86 or x64 binaries that aren't found in the noarch binaries? What's best for high performance applications? Folding@Home does this with their controller:

  • Can you zip a file from command prompt?

    - by Aaron Bush
    I have a batch file that outputs a text file. I thought it would be nice if I could zip it up too. This will be used in an uncontrolled environment so I can't make assumptions about the presence of 3rd party software products such as 7-Zip etc. This needs to use Window's now-built-in capability to zip files.

  • Running Multiple Instances of Firefox

    - by Aaron Bush
    I am running SysInternal's Desktops 1.02 and FireFox 3.6.2. I have noticed that while I can have IE8 open in multiple Virtual Desktops, you can not Firefox. If you try you get the error message: Firefox is already running, but is not responding. To open a new window, you must close the existing FireFox process, or restart your system. I did a little digging around to work around this and came up with creating a second profile via the Firefox profile manager (accessed by starting FF with the "-p" switch). This unfortunately created a new problem which is my add-ons (of which I use many) do not stay synchronized between profiles. Is there a better approach here?
