• Terminal app on Mac OS X - normal keys

  - by Matthew

  There are some default terminal things different for the Mac (for example, Command C to copy and Command V to paste rather than simply highlighting/right clicking). These are fine with me. What bothers me though is I can't figure out how to click or use the F keys. The main app I have problems with is htop. Htop supports clicking on column names to sort, etc. Also, to exit the app, you are supposed to press F10. But F10 simply mutes my volume. I've tried different combinations of things like alt F10. I usually have to quit htop by pressing CTRL-C Any ideas on how to get normal terminal behaviors? Normal meaning linux

• postfix header_checks using regexp proper setup

  - by Philip Rhee

  I just can't seem to figure out why header_checks are not being evaluated. I'm on Ubuntu 12.04, postfix 2.7, dovecote, spamassasin, clamav, amavis. I add following line to /etc/postfix/main.cf : header_checks = regexp:/etc/postfix/header_checks And here is header_checks : /From: .*/ REPLACE From: [email protected] To test out regexp : #postmap -q "From: <werwe>" regexp:/etc/postfix/header_checks which evaluates correctly and give me return output of : REPLACE From: [email protected] However, when I try to send email from commandline or from php webpage, postfix will not replace the From header. I'm stumped.

• Providing a public Web-Hosting service on MS Windows - advice and resources

  - by crgnz

  Are there any resources offering advice on how to setup a microsoft based web-hosting service? I currently offer LAMP hosting with cPanel, but there is some demand for IIS & SQL Server. As far as I can tell MS Windows Web Server 2008 R2 edition allows unlimited IIS connections. And a per-processor license for MS SQL Server Web Edition 2008 also permits unlimited connections. Where I am falling down is that I can't figure out how to get "unlimited" Active Directory users. I can't use 2008R2 Web Server edition for AD, so I will need the 2008R2 standard edition, I think. Does Microsoft have a provision for using AD in an ISP scenario? I am looking at using the cPanel Enkompas system to manage the Windows software, and Enkompas requires AD for user authentication. Any advice would be greatly appreciated!

• Excel 2011 for Mac VLOOKUP Date Issue

  - by Mitch

  I'm fairly proficient in using vlookups, but I'm having an issue vlooking up dates between two different spreadsheets. =VLOOKUP(B6,'[example.xlsx]Sheet1'!$B$1:$AA$260, 19, FALSE) My formula is retrieving a date fine, but the date is different when the cell is formatted for a date. Yet, when I change the formatting on each spreadsheet to display the date as a number, the number is the same (40115). The dates are displaying differently in each spreadsheet and I can't figure out why, they differ by about 3 years and 1 day (10/30/13 vs. 10/29/09). One was previously .xls, but I saved both a .xlsx. Thanks.

• How to calculate time spent for Linux system administration?

  - by Jaakko

  I would love figuring out how much time I actually have spent in shell performing administrative duties. For billing of course, this information is not sufficient, but it would be helpful to figure out how much time I have actually spent in shell. My question is: How anyone got tips on how to calculate time spent in shell (in hours + minutes), let's say per user account? Could anyone recommend a software that could be used to analyze this time? Optionally I would like to know about ways how to categorise time spent (e.g. 1 hour for Apache, 2 hours for Samba, etc.) Also, your takes on how you monitor your admin time, are also much appreciated! To narrow down the problem, I am specifically interested in ways of tracking time spent in shell for Linux system administration

• Server-to-Switch Trunking in Procurve switch, what does this mean?

  - by MattUebel

  I am looking to set up switch redundancy in a new datacenter environment. IEEE 802.3ad seems to be the go-to concept on this, at least when paired with a technology that gets around the "single switch" limitation for the link aggregation. Looking through the brochure for a procurve switch I see: Server-to-Switch Distributed Trunking, which allows a server to connect to two switches with one logical trunk; increases resiliency and enables load sharing in virtualized data centers http://www.procurve.com/docs/products/brochures/5400_3500%20Product%20Brochure4AA0-4236ENW.pdf I am trying to figure out how this relates to the 802.3a standard, as it seems that it would give me what I want (one server has 2 nics, each of which is connected to separate switches, together forming a single logical nic which would provide the happy redundancy we want), but I guess I am looking for someone familiar with this concept and could add to it.

• Resolving real IP address out of a dynamic dns address

  - by stavnir

  I recently opened a dynamic dns user (at no-ip for that matter..) for my own personal needs and especially for ssh-ing my computer whenever I need to, without knowing it's static IP. My questions are: Am I misusing the concept of dynamic dns? Are there more appropriate methods to do what I want to do? If not, how do I resolve my router's real ip address? Firefox somehow manages to do so, nslookup and other similar commands only resolve the ip of the ddns server (e.g. no-ip.org). Trying to figure this mystery with wireshark failed miserably ;)

• How to mail merge a hyperlink in Microsoft Word or Publisher 2010

  - by hjoelr

  I am trying to do an e-mail merge in Microsoft Publisher 2010 (which appears to do mail merging like Microsoft Word) and I'm wanting a merged email address to automatically be hyperlinked in the resulting email. For example, one of the merge fields could be "EmailAddress" with an example address being [email protected]. In the document, I would want the merge field "EmailAddress" to display as the default text in an hyperlink and also set the target of the hyperlink to "mailto:EmailAddress" (eg. mailto:[email protected]). I can't figure out how to get Publisher 2010 to do that. I would think that it's possible, though. Any help or pointers would be greatly appreciated!

• How to recursively move all files (including hidden) in a subfolder into a parent folder in *nix?

  - by deadprogrammer

  This is a bit of an embracing question, but I have to admit that this late in my career I still have questions about the mv command. I frequently have this problem: I need to move all files recursively up one level. Let's say I have folder foo, and a folder bar inside it. Bar has a mess of files and folders, including dot files and folders. How do I move everything in bar to the foo level? If foo is empty, I simply move bar one level above, delete foo and rename bar into foo. Part of the problem is that I can't figure out what mv's wildcard for "everything including dots" is. A part of this question is this - is there an in-depth discussion of the wildcards that cp and mv commands use somewhere (googling this only brings very basic tutorials).

• Can someone explain the fascination with twitter.com? [closed]

  - by raven

  I don't get it. WTF do people see in this? I'm trying to figure it out, but I can't. Have you seen what people post? Let's use Jeff Atwood as an example. What does he gain by posting (with disturbing frequency) all those, well... posts (I find the term "tweets" disgusting). What is a "follower" supposed to get from these posts? I know many of you are thinking, "Just don't use it!". Yes, I know I don't have to use it, but it's like asking me not to look at the space shuttle that just crashed in my front yard. The rest of the world thinks it's the greatest thing since sliced bread. I'm just trying to understand what people see in it.

• Can't initialize drive in Windows 7

  - by Abe

  I have a 2.5" laptop harddrive that I plugged into my laptop through a SATA to USB cable. It's powered by an adapter to a normal wall-plug. I want to use it as an external harddrive. It wouldn't initialize (Device is not ready), so as suggested in some instructions I found I uninstalled the drivers, unplugged it and plugged it back in. That worked, and I initialized the drive and formatted it. However I unplugged it after that and a few days later the same strategy does not work and I can't figure out how to use the drive. I can't initialize it and it doesn't show up in my computer.

• What does drag lock do in boot camp?

  - by MacBookNewb

  In the control panel for my mac book pro I have an icon called Boot camp. Inside there and inside the trackpad tab I have an option called drag lock. It sounds useful to me as I sometimes find it awkward dragging long distances. I can't figure out how to use it though. Can someone explain how I can find out more info on drag lock? I can't find any references on google. Also even without the dragging option on I can drag.

• migrate SharePoint to SBS Server

  - by Eric Lorson

  We have a SharePoint 2003 server and we need to migrate that data to SharePoint 2011 on a SBS server. We cannot use the migration tool because one of the servers is SBS and the other is not. We exported the SharePoint data from the old system, but the import to the SBS SharePoint is failing with very little info on why. I think that there is a schema conflict, but I am not that familiar with SBS and I am not finding the error in the Windows logs. Has anyone had to migrate data from non-SBS system to an SBS system? Or can anyone help me figure out where to look for more info on what is going on?

• Maximum disk size for a Debian 6 VMware installation?

  - by Mohamed Abobakr

  I'm planning to install a variety of Linux distributions on VMware Player to get more experience with Linux (I've only used Fedora back in university). I'm starting with Debian 6.0.5 Squeeze, and have already downloaded the small CD i386 netinst image. In the new virtual machine wizard, it's asking me for the maximum disk size of the image. It says that the recommended size for Debian 6 is 8 GB. However, I'm trying to figure out what is the absolute minimal size that I can get away with, since I'm only testing it out with very few software installations (mainly testing web server applications).

• PostgresQL on Amazon EBS volume, realistic performance, or move to something more lightweight?

  - by Peck

  Hi, I'm working on a little research project, currently running as an instance on ec2, and I'm hoping to figure out whether I'm going down the right path. We, like a thousand other people, are making use of some of twitters streaming feeds to do gather some data to have fun with and my db seems to be having problems keeping up, and queries take what seems to be a very long time. I'm not a DBA by trade, so I'll just dump some info here and add more if need be. System specs: ec2 xl, 15 gigs of ram ebs: 4 100 gb drives, raid 0. The stream we're getting we're looking at around 10k inserts per minute. 3 main tables, with the users we're tracking somewhere in the neighborhood of 26M rows currently. Is this amount of inserts on this hardware too much to ask out of ebs? Should take a look at some things with less overhead like mongodb?

• USB cable model for Kodak EasyShare Z740

  - by Robert Munteanu

  I've lost the original USB cable for my Kodak EasyShare Z740, and I can't figure out which model I should replace it with. I did not find the original parts, as the camera is pretty old. I did find the cable on the Kodak site, but I I've tried both mini-USB and micro-USB and neither fit. Alternatively, bonus points for pointing out a dealer in Bucharest, Romania which has the original part. N.B. I do use a card reader now, but I find it more convenient to use the cable.

• /dev/fuse "permission denied" even when member of fuse group

  - by steeef

  I have a backup script scheduled on a Debian 5.0 x86 server, via sshfs. However, when I attempt to mount the remote directory, I receive: failed to open /dev/fuse: Permission denied ls -l /dev/fuse returns: crwxrwxr-x 1 root fuse 10, 229 2010-11-12 09:08 /dev/fuse id backup returns: uid=501(backup) gid=501(backup) groups=501(backup),46(plugdev),108(fuse) The only way I can get the directory to mount is if I run chmod a+w /dev/fuse, but this is reset at some point during the day. It's a kludge though, and I'd rather figure out why the group permissions aren't working.

• Tomcat - virtualhosting - name / ip / port - based

  - by lisak

  Hey, what are the usage scenarios for these kinds of virtual hosting ? Name Based - typical tomcat virtual hosting, one HOME instance with many contexts, each as an individual host IP based / port based - multiple instances of tomcat ( how is it with performance and memory consuption?) running on IP aliases (virtual IPs) for one network adapter, usually behind http apache server that can run name based virtual hostings. Otherwise I can't figure out how would I forward requests in iptables/firewall based on IP address, which is just one. How is IP based virtual hosting done as to Tomcat and multiple instances ? I'd like to hear some usage scenarios from your experience. How are you running your applications. Cause there are applications having it's own modified classloader and they are developed in a way to run alone withing a tomcat instance. Then there are trivial applications which can run within one instance without problems. Many thanks

• Using Excel data in Microsoft Publisher

  - by TK

  I have never worked in Microsoft Publisher. To build the presentation we're having to input the same information from a microsoft excel master. For instance- My excel has these columns: Item Title, Item Description, Item Dimensions, Notes, Created Date From there, I'm having the RE-type the information underneath a picture of the item in powerpoint (or publisher) in order to present to the client. So I'm retyping the item name, description, dimensions, etc. I'm also reformatting slides each time I do this. I know there's a way to streamline this process, to build a powerpoint and/or something in publisher that will bring in the data needed based on a merge (or maybe macro), but I haven't been able to figure out how. Any suggestions?

• MediaTemple DV SSL and Passenger

  Followed these instructions to get Passenger and media temple's apache talking to each other. http://greggoodwin.com/2009/03/01/install-ruby-on-rails-with-passenger-on-mediatemple-dv-35-how-to/ I have ssl_requirement installed and pages requesting SSL but can't figure out which .conf file gets edited and what to put in it. httpd.conf, vhosts.conf, ssl.conf, vhosts_ssl.conf? For what its worth where my vhosts.conf file is at, there is also a httpd.include that looks like it holds some info from certs created by Plesk. In there it says to create a /var/www/vhosts/sitename.com/conf/vhost_ssl.conf file for ssl. Currently I have vhosts.conf in /var/www/vhosts/sitename.com/conf/vhosts.conf And it looks like ServerAlias www.sitename.com DocumentRoot /var/www/vhosts/sitename.com/rails/sitename/public <Directory "/var/www/vhosts/sitename.com/rails/sitename/public"> Options FollowSymLinks AllowOverride None Order allow,deny RailsEnv development Allow from all </Directory> RailsBaseURI /

• ASP.NET website http requests appear to be queueing

  - by scolemann

  We cloned our servers this weekend into a colo. All non-asp.net sites are performing great, but ASP.NET sites are very slow. It appears to be an issue with the requests/connections, but I cannot figure out where. The reason I think it is a problem with the connections is that when I launch fiddler and watch the requests, all requests appear to happen sequentially. Even the static image requests are taking 5 seconds and another one doesn't start until the first one finishes. MaxConnections is set to 100 in machine.config and the "website connections" are set to unlimited. Any idea what else coudld be causing this? from machine.config:

• Grep the whole body of a function

  - by dotancohen

  Supposing I know that someFile.php contains the definition for someFunction(). How would I go about displaying the whole body of the function in stdout? If I know that the body is 10 lines long then I would use cat someFile.php | grep -A 10 "function someFunction" [1] but in reality the function could be any arbitrary length. I figured that with sed I could use Vimesque commands such as /function someFunction<Return>/{<Return>% [2] but I can't figure out exactly how to format it. Ideally, the PHPDoc before the function would be output along with the function. Any help or links to the appropriate fine manual would be appreciated. Thanks! [1] I know that the cat is redundant, but I find this format easier to read. [2] Find the function definition, go to the opening brace, go to the close brace

• How do I open WPS files in Word Starter 2010?

  - by Sean

  Ok, this is driving me crazy. My parents have 100s of old WPS documents from an ancient version of MS Works, and they just bought a new computer with MS Word 2010 Starter on it. I ap trying to set it up so that the default program to open the WPS files is MS Word, but there is no EXE anywhere in program files or programfilesx86. I opened up process explorer and tried to figure out where the executable for Word is, and it turns out it is on the Q drive... the same Q drive that seems to be inaccessible no matter what I try. I tried adding the exact address of Word, but if I try and set that on anything, it says that it cannot find the file. This is driving me insane, is there any way to make it real easy to open these WPS files in Word?!?

• tomcat dns forwarding to multiple applications

  - by basis vasis

  I recently installed business objects software on tomcat 6. I have 2 domains - domain1 and domain2. This software allows access to two of its applications via these URLS: ADDRESS:http://myservername.domain1:8080/BO/APP1 and ADDRESS:http://myservername.domain1:8080/BO/APP2. Instead of these urls, I would like the end users to access these apps via something like http://bobj.domain2.com:8080/BO/APP1 and http://bobj.domain2.com:8080/BO/APP2. I cannot figure out how to accomplish that. I have looked into the option of http redirect (not good because the destination address shows up in the address bar), domain forwarding (not sure if it would work with multiple applications and forwarding from one domain to another) and also using apache tomcat with mod_jk by using virtual hosts (not sure if it is possible when forwarding from one domain to a sub domain in another domain) ?? please advise as to what would be my best option and how to accomplish. thanks a bunch

• A font like RomanS in appearance but with support for more characters (Autocad)?

  - by kokbira

  In a Autocad 2010 installation, the standard font used is RomanS. That font is so limited on characters, so when I use "text" command I cannot add "³" on text of cubic meters measures (a "?" is displayed instead of the "³" character - see isolated text on figure below and Font characters Latin Supplement range). When I use a dimension command, like multileader, Autocad "corrects" that issue using another font that support that missing character, resulting on an awful mixture (see text on multileader below - on multileader text properties, we can see 3m{\fArial|b0|i0|c0|p34;³}). I can easily change that font with another, like Verdana, Times New Roman... that have more characters than RomanS font, but I would like to use an alternative font more like RomanS in appearance. Any help?
