• Optimal Instance Size for EC2 Sharepoint Server

  - by Rob Wilkerson

  I'm surprised that I can't find any info about this, but I'm not a Windows admin and just a novice EC2 user. I have a client who wants to stand up a Sharepoint server on EC2 for internal use. The team is small (10-20) folks and traffic will be light. Mostly, the client is looking for one place to store documents (and revisions of documents) while making access easy for authenticated users anywhere in the world. They've settled on Sharepoint and have other EC2 instances so that seems like the natural fit, but I'm trying to figure out what to recommend for them. I'm currently thinking about a Medium instance. I'm afraid to go smaller because I think Windows would need a fair amount of memory just to run, but I'm very open to suggestions. Any advice would be much appreciated. I expect that the storage itself would happen in an EBS mount, but again, suggestions welcome. Thanks for your input.

• Why my browsers display XML files as blank pages?

  - by n1313

  Every time I open an XML file, all I get is blank page instead of tag tree. The file itself is correct and loads okay, I can see it via View Source or in the Firebug. I've tried turning off all my addons and tried running Firefox in safe mode, but the problem was not solved. I'm guessing that I've messed up my configuration somehow and Firefox now tries to render XML files as HTML ones. I've tried googling, but with no success. Help, please? UPD: example file: http://lj.lain.ru/3/1273657698603.sample.xml Also I've noticed that somehow all of the browsers on the machine are now acting the same, so I'm changing the question accordingly

• Changing Vim Home Directory

  - by mcaaltuntas

  Previously I've been using vim without any problems. However a few months ago our company made some network and security updates. After that whenever I plug a network cable into my laptop, it creates a network shared drive "H" with my company name and when I try to open vim it doesn't load plugins and other things that are in my vim home directory. I have found the reason but I don't know how to solve it. The problem is that these network updates changed our HOME directory. When I write: echo $HOME It prints H. Before plugging in a network cable my home was C:\Users\blabla. How can I change my HOME variable? When I run set it prints: C:\Windows\System32>set | findstr /R "^HOME" HOMEDRIVE=H: HOMEPATH=\ HOMESHARE=\\companyname\blabla\username$

• 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.

• Video encoding for archival

  - by Jim

  I would like to archive some home videos (DV). I don't need to save them losslessly, but I would like to encode them in something high-quality. What format is both pretty indistinguishable from the original and will likely be readable 15 years from now? WMA makes me nervous, because it's only one company that makes it, and they're constantly coming out with newer formats. (VLC couldn't open my WMAs that Windows Movie Maker made.) Other things I've considered are h.264, Ogg Theora, DivX, and Xvid. I don't mind paying for something, but usually that means the format is owned by only one vendor.

• Acrobat keyboard stealing in Firefox

  - by Uiy

  There are times when I open a pdf in firefox(which uses the acrobat plugin) and the "pdf" steals control of the keyboard. The arrow keys do not work in other programs. Well, If I hold them down they will then work but it becomes hard to navigate that way. It seems acrobat installs a global keyboard hook in some cases and takes control of the keyboard. This didn't start happening until recently(a few months ago). Note that it doesn't happen on all pdfs and everything returns to normal when the pdf is closed. This seems to be an issue with acrobat... maybe a setting? Anyone have any ideas what is going on?

• Moving windows using keyboard...faster?

  - by Alois Mahdal

  I like using keyboard shortcuts because it's faster as it does not force me to move my hands off the keyboard. In Windows I can use them to move windows around desktop: Press Alt+Space to open common windows menu Press M to choose "Move" command Navigate window position by cursor keys Confirm new position with Enter Additionally, to achieve better accuracy, I can hold Ctrl while navigating. Now the problem is that the normal "step" when moving is about 20px, and my desktop is quite large, so "walking" all the way across takes quite a long time. This kind of defeats the purpose of using keyboard for these tasks. Is it possible to change size of this step so that takes less steps to walk the same distance? (I imagine a hidden setting in Windows registry...?) I tried holding Alt while navigating, but it does not seem to have influence on speed.

• How to get notifications from Windows Update when optional updates are available?

  - by Tom

  On my Windows 7 I set windows update to "download updates, but let me choose whether to install them". The problem is I don't get a notification when an optional update is available like definition updates for microsoft security essentials. I have "give me recommended updates the same way I receive important updates" checked, but I have no notification balloon or icon when there is a new optional update is available. From time to time I open Windows update and then I see I have new optional updates available. How to get notifications for those too?

• Postfix configuration w.r.t. port 25

  - by Monkey Boson

  After a considerable amount of research, I have configured my postfix server to use dovecot to accept SMTPS connections over port 465 and everything works swimmingly. Unfortunately, I forgot that, unless I listen to port 25, I'm not going to receive any e-mail from the net. I'm hoping somebody knows off the top of their head how to open up port 25 on Postfix for anonymous users, but disallow relaying and any other bad things on that port. And to leave the port 465 the way it is. As to my current configuration, I changed the master.cf file: smtps inet n - n - - smtpd and the main.cf file: # Use our SSL certificates smtpd_tls_cert_file = .....cer smtpd_tls_key_file = .....key smtpd_tls_security_level = may # Use Dovecot for SASL authentication smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_sasl_authenticated, reject_unauth_destination Any help is appreciated!

• switch OFF syn cookies

  - by Nick

  We have several servers they have public IP's, but work together (one is with Load Balancer, orther with Apache Web server, other with MySQL and so on. Most of the ports are fire-walled, so only "local" servers can be connect there. However ALL servers have some ports that must be publicly open. We have SYN Cookies enabled and from time to time we got: possible SYN flooding on port 8080. Sending cookies. Port 8080 is not public. How we can switch OFF SYN Cookies for some ports (e.g. 8080, 3306 etc) or from some sources (e.g. our servers), but in same time SYN Cookies to be switched ON for all other ports, e.g. port 80. We found this similar problem, except our servers are with public IP's: SYN cookies on internal machines

• How to fix Windows XP from muting sounds on every startup?

  - by Rookie

  This started to happen few days ago: Every time I start up my computer, the global sound volume ("Playback") is set to muted (from the checkbox), in the sound control panel. So I have to open the control panel every time i start up my computer, and click that checkbox. I have got this bug before, long time ago. I have no idea why is this happening. Any ideas how to fix this or what is causing it? I have SP 3 and most updates installed a half year ago or less.

• What is the easiest way to make your browser refresh a page every say, 5 seconds?

  - by Oren A

  Is there a browser that supports refreshing a page every say, 5 seconds? Is there an add-on? If not, is there a more simple way than writing a full (C# or Java) program in order to do that? Added: Opera is horrible! I set Stack Overflow to refresh every 5 seconds, but when I click on a post, it refreshes it every 5 secs too! I just wanted the main page to refresh every 5 seconds. Another "Added": apparently it refreshes the current tab, so as long as I open the post in a new tab, it works great.

• Windows 2008 Server Unable to activate with other methods

  - by matt king

  I'm trying to activate windows 2008 server SP2 today since the activation trial is done. I do not have an internet connection with this server so I can not activate online, and with the other servers in this farm I've been able to run the slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx and then it would open up the activate by phone method and we would just activate that way. I say again, I don't have an internet connection so I can not do the online activate. If I do the slui 4 it brings up the activation window but show me other ways to activate is still greyed out. I've disabled the NIC on this Hyper-V server and I still can not get the other way to activate to show up... Anyone have any ideas? This computer is one of my AD servers so.. it being in notification mode kind of sucks. Thanks.

• Cannot connect to FTP server from external host

  - by h3

  I have a FTP server (vsftpd) setuped on a Linux box (Ubuntu server). When I try to connect with a computer on the same network everything works fine as expected. But as soon the IP is external it won't connect.. I first assumed the port was blocked, but then: localserver:$ sudo tail -f /var/log/vsftpd.log Wed Jan 13 14:21:17 2010 [pid 2407] CONNECT: Client "xxx.xxx.107.4" remotemachine:$ netcat svn-motion.no-ip.biz 21 220 FTP Server And it hangs there .. Is there any other ports other than 21 that are required to be open ?

• Getting data from closed files with concatenate formula

  - by Pav

  Each day a program is creating an excel file for me with some data for the current day. Like what is the price for products, how many people are available today and things like that. Based on all this I need to make some forecasts and workplace allocations for workers. The problem is, that I need to drag all this information manually all the time. So to make it automatic I placed the formula in cells like: ='c:\ABC\[ABC 29-01-14.xlsx]sheet'!a1 Everything works fine, but next day I have to change file name for "ABC 30-01-14" for each cell, what is the same as entering the data manually. So I used "concatenate" formula to change date according to today's date automatically. I used "indirect" formula to turn it in to a real formula, not text string, and realized that it is working only for open files, not closed. Is there any way to do this for closed files without VBA, because I don't know it, or with VBA but explained for an idiot.

• hardware: delay and distinct 'click' before hard drive access

  - by matt lohkamp

  I have a windows 7 box stashed away in my closet, containing (among other things) 2 big HDDs linked together as a mirrored volume - basically a super lazy NAS / media server. I've noticed that when that drive is accessed (whether locally, on the machine itself, or remotely, from another computer, or my xbox, for example) there's a noticeable pause, and then from the computer itself, a 'click!' noise, after which the drive is accessed; e.g. open \\computername\shared\, wait 2 seconds, hear 'click!' and then see files appear in windows explorer. Any ideas? Otherwise the drive preforms normally - is it a windows thing? a HDD-about-to-die thing? Or a "yeah that always happens, you've just never noticed it before" thing?

• Taking stock of an existing ASA Firewall

  - by Nate

  Imagine you are given an existing network using an ASA firewall. The network works, but you aren't sure of anything else. The firewall may be completely improperly configured, with "outside" actually being inside and "inside" actually being outside, for all you know. My question is this: what are the commands to take stock of an existing ASA firewall setup? With only CLI access, how do I figure out: What interfaces are available The names of the interfaces The security levels attached to the interfaces The access-lists attached to the interfaces, including rules and directions I know how to set these things (interface, nameif, security-level, and access-list/access-group), but I don't know how to figure them out given an existing system. On a related note, is there anything else that I should worry about checking to make sure that the network isn't wide open? Thanks!

• Run shell command with variable in filename via Python

  - by rajitha

  I have files with naming convention st009_out.abc1.dat st009_out.abc2.dat st009_out.abc3.dat .................. .................. I am writing Python code where I want to use data from the file to perform a math function and need to extract the second column from the file. I have tried it this way: for k in range(1,10): file1=open('st009_out.abc'+str(k)+'.dat','r') ........... os.system("awk '{print $2}' st009_out.abc${k}.pmf > raj.dat") but this is not working as it is not taking the value of k in the shell command. How do I progress?

• Why does Windows Explorer highlight only second entry?

  - by normanius

  Why does Windows Explorer highlight the second but never the first entry if I use the keyboard for navigation? Example: let's look at a folder that contains the following entries a1 a2 a3 b1 b2 If I hit 'a' on the keyboard, the explorer highlights entry 'a2' instead of 'a1'. It works fine for 'b' with 'b1' (because it's not the first entry). Similarly, if I open a folder and use the arrow-down key to navigate then the first entry is skipped again. Why?! It's probable that I'm too stupid for this but this "feature" really annoys me!

• How to make changes in linux maintence mode

  - by Jack

  I notice when Linux boots in maintenance mode the filesystem is read-only. Is there a way to change this, perhaps remounting as writable? An example of this being a problem is that I was unable to open vi because there were too many session files.... Not to mention it would be nice to actually fix problems.... What are you meant to be able to do if you can't make any changes to the filesystem? What kind of maintenance can be expected?

• Exited Emacs without saving, did it save the file somewhere?

  - by rumtscho

  Hi, I am using Emacs on Windows XP. Had it open to take some notes in a meeting, but forgot to create a file first (the text got created in the usual "scratch" buffer). Then I closed a lot of applications after the meeting, forgetting to save the notes in Emacs :( I know that when I am modifying an existing file, it creates a backup of the old file in the same directory. But I don't know if the information from the scratch buffer is available somewhere after an exit without saving. Do you know if I can restore my information? I haven't shut down/suspended/hybernated the system since, so all temp files should be still accessible.

• HP DV5T laptop problems using Adobe in multiple monitors

  - by Rolnik

  I have a dualview arrangement of two monitors that works just fine for 90% of my applications. However, any time I open Adobe Acrobat Reader to the larger monitor, it fails to permit enlarging of the window to fill the entire screen. In other words, it seems Adobe crops the PDF view at about the size of the smaller of the two monitors, despite Acrobat being present in the larger monitor. I'm using nVideo graphics on the laptop, and connecting to the larger monitor through the docking port of a docking station. Any ideas how to get the Acrobat to be aware that it has more screen real-estate and use it fully?

• How do I stop ssh-agent from forgetting my password after I login to the screen session from SSH?

  - by Shwouchk

  I have a screen session open in an lxterminal window. If I SSH somewhere, the first time it happens, an ssh-agent window opens and asks me for my private key passphrase, and after that ssh goes right on. If I log in from outside to this machine and attach to the screen session however, ssh-agent now asks me every time I connect for my passphrase, in the terminal. Is there a way to avoid this and to let it continue using the X agent, or at least to have the non-X agent remember the passphrase?

• Why is the pavucontrol level indicator jumping while nothing plays?

  - by EnterTheLiquidToasterFamily

  The level indicator in the screenshot does jump around even if nothing is playing. The indicator also reasonably represents sound levels when music is playing. I dont have any mediaservers running or noisy browsertabs open. Also no mic connected. When I turn the volume to max in software and on the amp, there is no noise from the speakers at all. Played music is loud and not distorted. Hardware: Realtek ALC889 over optical audio connector to a generic amp. Software: Debian Wheezy with latest backport kernel 3.14 (same thing on wheezy 3.2 stock), wheezy pulseaudio, xfce session, a custom asound.conf that enables pulseaudio to push sound over optical port. /etc/asound.conf pcm.a52 { @args [CARD] @args.CARD { type string } type rate slave { pcm { type a52 bitrate 448 channels 6 card $CARD } rate 48000 #required somehow, otherwise nothing happens in PulseAudio } }
