• How can I get bash to perform tab-completion for my aliases?

  - by dstarh

  I have a bunch of bash completion scripts set up (mostly using bash-it and some manually setup). I also have a bunch of aliases setup for common tasks like gco for git checkout. Right now I can type git checkout dTab and develop is completed for me but when I type gco dTab it does not complete. I'm assuming this is because the completion script is completing on git and it fails to see gco. Is there a way to generically/programmatically get all of my completion scripts to work with my aliases? Not being able to complete when using the alias kind of defeats the purpose of the alias.

• Duplicate Name Exists error from virtual PC with NAT network configuration

  - by Phred

  Whenever I change the network configuration to NAT for a virtual machine running under Virtual PC 2007, I get "A duplicate name exists on the network." error. There is no other machine on my network with this name and running the VM in any other network configuration doesn't cause this error. This seems to be a common problem with Virtual PC 2007 based on a google search but no-one seems to have a solution to it. So far, I've discovered that turning off NETBIOS over TCP causes the problem to go away but I need to join this VM to a domain and you can't do that if NETBIOS over TCP is turned off.

• Got root, now how should I configure my server?

  - by L. De Leo

  I've been a developer for years and by trade I had to know a little bit of server side configuration. But now I find myself needing to manage my own VPS instance (Amazon EC2) and I'm lost. I'd like to know what are the common ways to configure an Apache and MySQL server that is secure and efficient. For example right now I'm doing everything as root but I doubt that's the best way at all. My whole Apache is configured to serve 1 site when I'd like it to be able to serve multiple sites. Where do I start?

• Failing Seagate HDD - Not Recognised

  - by thefragileomen

  I am having a look at a friend's computer which contains a 500GB Seagate HDD. Unfortunately the HDD is not recognised by the BIOS menu and it beeps 11 times upon powerup. I've moved the HDD to another laptop but the problem remains. I've downloaded SeaTools for DOS (Seagate's Diagnostic tool) but unfortunately to no avail and the disc remains unseen when using this DOS boot disc. The HDD is only 6 months old so I'm very surprised at this but it appears a common problem with Seagate 2.5" HDDs as well as other HDDs manufactured by Seagate. I intend to try it in an external caddy on Thursday when back in work and also through a forensic writeblocker but just wondering if anyone has any other suggestions? I am of the opinion it is some chip on the HDD board which prevents it spinning due to a fault. If so, I've lost to deactivate this just so I can simply recover the data on the drive and start with a new disc. Thanks

  I have asked question on http://stackoverflow.com/questions/9868426/i-need-to-know-which-email-server-i-have-to-use and someone tell me my question would be better on serverfault. I know that this is a common question and asked many times. but there are so many available mail servers that i am not able to decide the one.

• Suitable companion monitors for HP LP3065 30" primary monitor

  - by Bittercoder

  I have an HP LP3065 30" monitor - now I want to add a couple of companion screens to either side of it - I've heard to people suggesting 21" monitors in portrait mode - but it seems difficult to find a suitable panel these day, as 22" wide-screen monitors have become common, and I can't seem to find anything with a suitable 1600 pixel width. Can anyone recommend a suitable monitor, and suggest what criteria are best for picking a suitable monitor - what's important to consider - I'm thinking things like: Exact resolution match? Viewing angle? Small/thin bezel?

• Why do mapped drives only reappear after logging out and back in, and not after a reboot?

  - by razumny

  I work in a corporate environment, where we use mostly Windows 7 Professional computers, though some legacy applications are still being run on Windows XP. We have security in place on the network not to allow access to network resources to computers that are not members of Active Directory. When logging in, our users get their home folder and a common network drive mapped to H: and F:, respectively. Sometimes, this does not happen, and the drives are not mapped. The solution is to have the user log off, and back in to Windows. If they reboot, the drives remain unmapped. Does anyone know why this may be?

• Restore Point area getting deleted

  - by PaoloFCantoni

  Hi, I'm running a multi-boot scenario (which I have been successfully on a number of machines for a number of years). I have Windows 7 (32 bit) on one partition and Windows 7 (64 bit) on another and a common data partition (which happens to store the user hives for each OS instance). For some reason, on one particular machine (a HP Pavilion notebook) the restore points get trashed after a reboot. I can create them (both manually and automatically), but after some (but not all) reboots the restore points get trashed. I have all three partitions set (on both OSs) to hold restore information. This setup has worked successfully on other machines for at least 12 months. I'm out of ideas... I DO need the restore points as I do "bleeding edge" stuff and they've saved my bacon on other machines in the past... TIA, Paolo

• Title: Better logging for cronjob output

  - by Stefan Lasiewski

  I am looking for a better way to log cronjobs. Most cronjobs tend to spam email or the console, get ignored, or create yet another logfile. In this case, I have a Nagios NSCA script which sends data to a central Nagios sever. This send_nsca script also prints a single status line to STDOUT, indicating success or failure. 0 * * * * root /usr/local/nagios/sbin/nsca_check_disk This emails the following message to root@localhost, which is then forwarded to my team of sysadmins. Spam. forwarded nsca_check_disk: 1 data packet(s) sent to host successfully. I'm looking for a log method which: Doesn't spam the messages to email or the console Don't create yet another krufty logfile which requires cleanup months or years later. Capture the log information somewhere, so it can be viewed later if desired. Works on most unixes Fits into an existing log infrastructure. Uses common syslog conventions like 'facility' Some of these are third party scripts, and don't always do logging internally.

• can I make Excel always open a delimited text file with "text" translation?

  - by khedron

  Hi there, Opening a tab-delimited data file in Excel to view & manipulate the data is a very common operation around here. However, by default Excel (2003/4 or 2007/8) will read the columns in a "General" format, which occasionally does terrible things like turning "1/2" into "2-Jan". Is there a way to tell Excel never to do this, but always process the values as Text, without going through the format wizard, selecting all of the columns, and doing it manually? Extra points if this works in both Mac and Windows versions of Excel.

• Freelance for moderately complex admin support

  - by ongraphs

  Mailing lists and question/answers works great for problems that are independently encountered by several people. But sometimes we (as in experienced amateurs) run into problems that aren't so common, nobody has blogged about it and experts advice not readily available. For IT-admin related stuff can someone please recommend how can amateurs pay experts and get hands on advice. The kinds of problems I am talking about are like setting up nxserver or openvpn on freeBSD box. The install/config is not so simple, the documentation not easy for non-it professionals. Therefore getting step by step advice would be quite helpful. Thanks sandeep

• Restoring the Fonts folder by using a restore point

  - by ryalho

  I am an idiot. Who would have thought that installing 2 gigs of fonts would be detrimental to the boot up time for the most common design programs such as adobe illustrator. I would like to restore the font folder because I am no longer able to just delete the fonts. It takes too long. So when I right-click the fonts folder and select "Restore Previous Versions" I am able to find a restore point, but the "Restore" button is greyed out. this leads me to think that I cannot change the settings of files in the windows directory. Oh and there are 34,000 fonts I need gone. Thanks

• Top causes of slow ssh logins

  - by Peter Lyons

  I'd love for one of you smart and helpful folks to post a list of common causes of delays during an ssh login. Specifically, there are 2 spots where I see a range from instantaneous to multi-second delays. Between issuing the ssh command and getting a login prompt and between entering the passphrase and having the shell load Now, specifically I'm looking at ssh details only here. Obviously network latency, speed of the hardware and OSes involved, complex login scripts, etc can cause delays. For context I ssh to a vast multitude of linux distributions and some Solaris hosts using mostly Ubuntu, CentOS, and MacOS X as my client systems. Almost all of the time, the ssh server configuration is unchanged from the OS's default settings. What ssh server configurations should I be interested in? Are there OS/kernel parameters that can be tuned? Login shell tricks? Etc?

• Can't rename folders in Window 7/32bit after anti-virus change

  - by Tasos

  I recently started having the common, as I realized, problem of not being able to rename folders in Windows 7 (32 bit). I don't understand why it happened after almost a year of ideal use of Windows 7. I haven't removed the libraries nor can I think of anything else that could potentially cause this, at least as far as I know. The only thing I did recently was to change my anti-virus program from the freeware version of Avira to the freeware anti-virus Microsoft Security Essentials. Any idea on what the problem is and how to fix this?

• Application or plugin for turning screenshots into searchable text?

  - by Software dood

  It's a common practice in our company that people take screenshots of any software error situation they get into, and then they paste the screenshots in mail messages and/or Word documents that get sent and forwarded back and forth. I have lots of stuff like this in my Outlook mail archives, and the problem with it is, the screenshots aren't searchable, because they're just dumb images as far as Outlook or Windows Search are concerned. Sometimes I edit the original mail messages and type the text (typically an error message) from the screenshot into the message, but quite rarely, because it's slow and prone to typing errors. Is there a program or Outlook or Windows plugin that would OCR and index images in the Outlook mail archives, so the image contents would become indexable?

• Why does yum index get corrupted?

  - by TomOnTime

  Occasionally yum's cache gets corrupted and we see errors like this: error: db3 error(-30974) from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recovery error: cannot open Packages index using db3 - (-30974) error: cannot open Packages database in /var/lib/rpm The workaround is rm -f /var/lib/rpm/__db* and then the next "yum" command regenerates the data. My question is: what is likely to be causing this? Is there some common task that ignores locks or has other problem that causes this? We have hundreds of CentOS machines and there is no pattern to which see this problem. It could be a "one in a million" issue, which at large scale is seen often. NOTE: I realize this is a very "open ended" question, but if an answer finds the cause, I will go back and turn the question into something more canonical that directly relates to the specific issue.

• Windows hiding other user's files?

  - by JoshJordan

  I had a hard drive whose windows installation (running Vista) became corrupt. I bought a new hard drive, installed Windows 7, and hooked up the old drive using an external enclosure. The Users folder on the old drive shows the users that existed on the machine, but it doesn't show any of the contents of them. I assume this is due to not having the permissions I need. I have "taken control" of the folders I'm interested in, but this didn't prompt me for the original owner's password as I expected, and I still can't see the file contents. I would guess that this is a fairly common issue, but I'm not sure what to Google here. How can I get access to files in that drive's User directory?

• Disable CTRL + ALT + [LETTER] to produce accented variations

  - by Barney

  After an unknown config change, CTRL + ALT + [LETTER] has started producing common accented versions of [LETTER]. I'm not a big fan of this arrangement, seeing as I've memorized all my favourite ALT + [NUMPAD SEQUENCE] references and was used to using CTRL + ALT + [LETTER] for various other application-specific commands in my text editor. The prominent result from my searching suggests that this has something to do with a switch to an 'international keyboard', and says this can be removed in the control panel or toggled by hitting ALT + SHIFT, but I can't get my system to confirm this, and the solutions (or close approximations thereof) don't work. Specifically, I've been to Control Panel\Clock, Language, and Region\Language\Advanced settings and switched the override for default input method from 'language list' to English and I've been to Control Panel\Clock, Language, and Region\Language\Language options and made sure that I only have my one input method (UK). Other than that I'm not quite sure where to look. Any ideas?

• Ways to deduplicate files

  - by User1

  I want to simply backup and archive the files on several machines. Unfortunately, the files have some large files that are the same file but stored differently on different machines. For instance, there may a few hundred photos that were copied from one computer to the other as an ad-hoc backup. Now that I want to make a common repository of files, I don't want several copies of the same photo. If I copy all of these files to a single directory, is there a tool that can go thru and recognize duplicate files and give me a list or even delete one of the duplicates?

• Grep /var/log for hacker/script kiddy activity and e-mail?

  - by Jason

  CentOS 6 Apache Server version: Apache/2.2.15 (Unix) Thinking about how to automatically, once a day, grep all the logs in /var/log/httpd for hacker, phishing, etc activity and e-mail it to myself so I can evaluate what I might need to do. But what are the patterns I can look for? IE, we dont run Wordpress and we see a lot of attempts to access Wordpress related content, obviously for an exploit. Same with PHPMyAdmin. I could do something like repeatedly, matching common patterns we see. # grep -r -i wp-content /var/log/httpd/ # grep -r -i php-my-admin /var/log/httpd/ How do I e-mail myself this the results of each grep command or better yet all Grep results in a single e-mail?

• Data take on with Drupal 6

  - by Robert MacLean

  We are migrating our current intranet to Drupal 6 and there is a lot of data within the current system which can be classified into: List data, general lists of fields. Common use is phone list of the employees phone numbers. Document repository. Just basically a web version of a file share for documents. I can easily get the data + meta infomation out, but how do I bulk upload the two types of data into Drupal, as uploading the hundred of thousands of items manually is just not acceptable.

• How do I set up my home server to go directly to a port other than 80

  - by Kevin

  I'm using dyndns, a lynksis wt54g router, and tomcat 7 with spring to set up a web server. This is my first time to attempt this. I'm sure this is a very common question, but I don't know enough to find the answer after quite a bit searching. Dyndns is successfully forwarding to my ip. The main problem is, the router admin login is coming up when my url is used. I'm hosting my site on port 8080. I have port forwarding set up for port 8080 but my request times out when I attempt to use my url like this www.myurl1234.com:8080. I don't want users to have to type the port anyway. I also tried changing the management port to 82 and hosting on port 80, but I still get the router admin login when I use my url. Where am I going wrong? Can I set it up so that www.myurl1234.com goes straight to port 8080?

• Why do Apache access logs - timer resolution issue?

  - by Rob

  When going through Apache 2.2 access logs, logging with the %D directive (The time taken to serve the request, in microseconds), that it's very common for a 200 response to have a given number of bytes, but a "time to serve" of zero. For example, a given URL might be requested 10 times in a single day, and a 200 response is sent for them all, and all return, say 1000 bytes. However, 7 of them have a "time to serve" of zero, while the other 3 have a time to serve of 1 second. Is this simply because the request was served faster than the resolution of the timer Apache uses?
