• Mitigating the 'firesheep' attack at the network layer?

  - by pobk

  What are the sysadmin's thoughts on mitigating the 'firesheep' attack for servers they manage? Firesheep is a new firefox extension that allows anyone who installs it to sidejack session it can discover. It does it's discovery by sniffing packets on the network and looking for session cookies from known sites. It is relatively easy to write plugins for the extension to listen for cookies from additional sites. From a systems/network perspective, we've discussed the possibility of encrypting the whole site, but this introduces additional load on servers and screws with site-indexing, assets and general performance. One option we've investigated is to use our firewalls to do SSL Offload, but as I mentioned earlier, this would require all of the site to be encrypted. What's the general thoughts on protecting against this attack vector? I've asked a similar question on StackOverflow, however, it would be interesting to see what the systems engineers thought.

• There is a problem with the Office database

  - by RomanT

  After a TimeMachine restore; office 2011 is having kittens over permissions it would seem. Having attempted a 'repair' out of Disk Utility, am still seeing: 'there is a problem with the Office database' upon startup. After which Word/Excel work without issues. Outlook on the other hand won't even start. Given the obvious message here "You do not have write access to the Outlook application folder" - where is the DB located to check?! Ideas ? Thank you

• Free, web based alternative to Visio?

  - by Lars

  I have used Visio to map out my network structure, and have used the export function to create an HTML page that is searchable by IP, hostname etc. This is a really nice tool and I use it often. However, I would like for users who do not use Internet Explorer to be able to use the search features. What are some alternatives to Visio here? I want to draw a network diagram where objects are searchable. Thanks!

• Excel fonts: Embedding or fallback options?

  - by Brendan

  I'm working with making a form in Excel instead of Illustrator or InDesign, as I typically do. One of the benefits about working with Adobe (and the subsequent PDFs) is that I control the fonts 100%. This is not the case when I am required to work with an Excel file that'll be passed around. So, is there a way to embed fonts? I'd like to embed Calibri. If not, is there a way to specify a fallback font, such as Tahoma? My thinking is along the lines of a CSS font stack; not sure if there's anything like that in Excel.

• Is Windows Server 2003 on 96 MB possible?

  - by Nifle

  I have an old laptop, a Pentium II with 96 MB. I have had Windows 2000 on it for ages, it was slow but usable. But now I have to upgrade since I can't get my USB-wlan drivers to install (the old PCMCIA network card broke). I would prefer to install Windows XP but I have no spare licence, but I do have a Windows Server 2003 licence. Do you think it's possible (and usable) to squeeze in 2003 on this computer? Edit: Unfortunately 2003 simply refuses to install on the laptop. It hangs with an error message (paraphrased) 2003 has detected a problem with your computer and has halted the installation to prevent damage. And then some error codes This happens very early in the installation while it's copying the installation files just after I accepted the licence. So I give up for now.

• Handout export to word from PowerPoint are too big :(

  - by nickjohn

  EDITED i am using power point lectures. i want to mail merge speaker data into the respective lecture. now thats not possible with ppt as far i know, so i have to convert these lectures to handout by using power point option "publishMS word handouts" and use word mail merger. this is good since it will keep the comments/notes added in slides in handouts aswell. but these exported handouts in word remain actual slides and retain link to original ppt rather than simply get exported as images. so the file size gets verrry big 10mb ppt = 212mb doc=88mb docx Is there any option to convert handouts exported from power point to word as images? i simply cant save them as pngs from powerpoint since that will not include the comments data. Thanks

• How to uploads to the web work on local networks

  - by Saif Bechan

  Let's say I have two computers hooked up as a home network. They both use the same router, and the router is hooked up to the to the net. Now lets say I am working on computer A, and I can access files on computer B. Computer A has a drive that is mounted on computer A as a network drive. Now I want to upload a file to a website. In the browser of computer A I open a browser, and go the website. On the website I select 'upload file', now in the file browser I go to the network drive, and select a file on computer B to upload. What happens in this case. Is the file uploaded directly from computer B to the website, or is the file first transferred to computer A, and then to the website.

• Subscript/Superscript Hotkey for Excel 2010 Macro?

  - by advs89

  Background In Excel 2010, for some ridiculous reason, there is no built-in hotkey (or even a button on the toolbar) for subscripting/superscripting text within a text cell. You can, however, highlight the text, right-click the selection, click format, and then check the [x] subscript or [x] superscript checkbox. Question Are there any kinds of excel macros or workarounds to map two keyboard hotkeys to the subscript and superscript keys, respectively? (It should only be, like, two lines of code - one for the event handler and one for the actual procedure call... I would write one myself but my VBA is rusty, at best, and I am pretty confident there is probably already some kind of solution, despite my inability to find one via search engine) Thanks for any help you can provide!

• Tools to extract text from powerpoint pptx in linux?

  - by felix

  Any there any linux tools that will extract the text from a Powerpoint pptx file? I tried catppt but it just returns file.pptx is not OLE file or Error. abiword --to=txt file.pptx also returns an empty text file. I can open the file in libreoffice but it doesn't seem to have an "export as text" option. As a guess I also tried libreoffice --headless --convert-to txt:Text file.pptx but that doesn't even return an empty file.

• Can't type text into table cell when form is protected in Word 2002

  - by Gus

  I created several tables in an Word 2002 document to act as a form for users to fill out. In some cells I added check boxes and dropdown lists for people to select options from. When I click on the Protect form button the check boxes and dropdowns become active; however, I can't type anything in the other cells. If I click in an empty cell it automatically moves to the next checkbox. When I unprotect the form then I can type in the empty cells but then checkboxes and dropdowns become useless. I know that the user can double click on the checkbox and then manually select to have it checked, but they can't do this with the dropdowns. What do I have to do to allow the user to type in responses to the tables cells and also select answers from checkboxes and dropdowns? Thanks!

• Ranking tables from Excel data

  - by Joe

  Hi all (asking here because this meta question told me to). I have some data in an excel spreadsheet here. It's no more than a table with about five columns. Year Purchased Manufacturer Model Num Unit Price Total Price 2007 SMARTBOX FuturePad XP 1 £2,915.00 £2,915.00 2007 Attainment Company Inc Go Talk 9+ 1 £104.00 £104.00 2007 Attainment Company Inc Go Talk 20+ 1 £114.00 £114.00 I'd like to be able to build a 'top ten' of either manufacturers or models (and I'd like to be able to do it by either most mentioned, most sales, or highest value of sales) - but I've got no idea what the best method is in excel. Any suggestions...? The ideal output might be a set of sells that says something like Company Units A 5342 B 232 C 2 D 1

• Force HTTPS with AWS Elastic load balancer

  - by panos2point0

  I need to redirect all incoming HTTP traffic to HTTPS on my elastic load balancer. I tired using Apache mod_rewrite: RewriteEngine On RewriteCond %{HTTP:X-Forwarded-Proto} !https RewriteRule !/status https://%{SERVER_NAME}%{REQUEST_URI} [L,R] Taking advantage of the X-Forwarded-Proto header added by the load balancer, this rule should instruct the users browser to request the HTTPS version of the same URL. So far It doesn't work (no redirection happens). What am I doing wrong? Is there a better way to do this?

• How to import this data set into excel? (column headings on each row delimited by a colon)

  - by Anonymous

  I'm trying to import the following data set into Excel. I've had no luck with the text import wizard. I'd like Excel to make id, name, street, etc the column names and insert each record onto a new row. , id: sdfg:435-345, name: Some Name, type: , street: Address Line 1, Some Place, postalcode: DN2 5FF, city: Cityhere, telephoneNumber: 01234 567890, mobileNumber: 01234 567890, faxNumber: /, url: http://www.website.co.uk, email: [email protected], remark: , geocode: 526.2456;-0.8520, category: some, more, info , id: sdfg:435-345f, name: Some Name, type: , street: Address Line 1, Some Place, postalcode: DN2 5FF, city: Cityhere, telephoneNumber: 01234 567890, mobileNumber: 01234 567890, faxNumber: /, url: http://www.website.co.uk, email: [email protected], remark: , geocode: 526.2456;-0.8520, category: some, more, info Is there any easy way to do this with Excel? I'm struggling to think of a way to convert this to a conventional CSV easily. As far as I can think, I'd have to remove the labels from each line, enclose each line in quotes, then delimit them with commas. Obviously that's made a little more difficult to script though seeing as some fields (address, for instance) contain comma-delimited data. I'm not good with regex at all. What's the best way to tackle this?

• Changing Word mail merge data source locations in bulk?

  - by Daft Viking

  I've just moved a number of Word mail merge files, and a number of Excel spreadsheets that are the data sources for the mail merges, from a Windows XP computer to a Windows 7 computer, and now all the paths for the merge sources are incorrect (used to be c:\documents and settings\user\my documents.... now c:\users\documents....). While I can correct the path of the data source in each file individually, I was hoping that there would be some way of updating the files in bulk, as there are a relatively large number of them. Word 2007 is what is being used, but the documents are all in the previous DOC format (not DOCX).

• Excel - pivot values in one cell (as comma-separated value)

  - by Chris

  Excel - pivot values in one cell (as comma-separated value) I have two columns of data: Supplier1|Product1 Supplier1|Product2 Supplier1|Product4 Supplier1|Product7 Supplier2|Product3 Supplier2|Product5 I want to 'pivot' around Supplier, and give the list of products in one single cell, comma-separated e.g. Supplier1|Product1,Product2,Product4,Product7 Supplier2|Product3,Product5 There's about 1000 suppliers, and 0 < products <= 10. My current workaround involves using pivot tables, saving as CSV etc and is very messy. A non-VBA solution would be amazing.

• Word 2007 "Out of Memory or Disk Space" Error on launch

  - by Adam

  Word 2007 is installed on a Vista Home Premium machine and whenever it starts up it opens what appears to be a dynamic installer to do something and then throws up the "Out of Memory or Disk Space" error. Word 2007 never completes starting up. Reinstalling Word hasn't helped and if I can avoid reinstalling Windows until Windows 7 is released and get Word working in the mean time, that would be ideal. I've been looking around for a solution, once of which seemed to point to a problem with the user account. I created a second user on the machine and Word still had the same problem. The other solution that seems possible is a corrupted normal.dot/normal.dotm file. However, even in the location it should be, I can't seem to find it. Am I going in the right direction with this? Is there another solution I haven't come across that will fix this? If it is possible that renaming normal.dot/normal.dotm how can I find it?

• I am getting a 400 Bad Request error when using Nginx and PHP-FPM, why?

  - by Bob

  I am trying to run a website (that requires PHP - it technically doesn't require MySQL at this time, but it may sometime in the near future as I continue developing it, so I went ahead and installed that as well) using nginx 1.2.4 and PHP-FPM 5.3.3 on Ubuntu 12.04.1 LTS. As far as I know, I haven't done anything wrong, but clearly something is not quite right - I seem to be getting a 400 Bad Request error whenever I try to browse to my website. I've been mostly following one guide, and I've done more or less everything it recommends, except for not setting up PHP-FPM to use a Unix Socket and I used service as opposed to /etc/init.d/ when starting/stopping nginx, PHP, and MySQL. Anyways, here are my relevant configuration files (I have only censored personal/sensitive details, like my domain name - which contains my real name): /etc/nginx/nginx.conf user www-data; worker_processes 4; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 15; types_hash_max_size 2048; # server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "msie6"; # gzip_vary on; # gzip_proxied any; # gzip_comp_level 6; # gzip_buffers 16 8k; # gzip_http_version 1.1; # gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; ## # nginx-naxsi config ## # Uncomment it if you installed nginx-naxsi ## #include /etc/nginx/naxsi_core.rules; ## # nginx-passenger config ## # Uncomment it if you installed nginx-passenger ## #passenger_root /usr; #passenger_ruby /usr/bin/ruby; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } /etc/nginx/sites-enabled/subdomain.mydomain.net server { listen 80; # listen for IPv4 listen [::]:80; # listen for IPv6 server_name www.subdomain.mydomain.net subdomain.mydomain.net; access_log /srv/www/subdomain.mydomain.net/logs/access.log; error_log /srv/www/subdomain.mydomain.net/logs/error.log; location / { root /srv/www/subdomain.mydomain.net/public; index index.php; } location ~ \.php$ { try_files $uri =400; include fastcgi_params; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /srv/www/subdomain.mydomain.net/public$fastcgi_script_name; } } All the directories listed in the configuration files above are correct on my server (to the extent of my knowledge). I have not included /etc/php5/fpm/pool.d/www.conf or /etc/php5/fpm/php.ini in this post as they're rather long, but I have posted them on Pastebin: http://pastebin.com/ensErJD8 and http://pastebin.com/T23dt7vM, respectively. Although, the only thing I've changed in either of the two files was in php.ini, where I set expose_php to off so as to hide the .php file extension from users. What can I do to resolve my issue? Please let me know if I need to supply any additional details.

• Does setting an A record for a root domain set it (automatically) for subdomains?

  - by Edan Maor

  I bought a domain from Dreamhost, but my servers are actually running on Amazon's AWS. I have an Elastic IP, say 1.1.1.1. In the Dreamhost panel, I've added an A record for my domain name, pointing it to 1.1.1.1. My question is, are all subdomains (e.g. www.mydomain.com, a.mydomain.com, etc.) automatically mapped to 1.1.1.1 as well, because the root is? Or do I have to add separate rules for each subdomain?

• Need advice on how to set up live video streaming to web/mobile devices

  - by jasondewitt

  I have a bunch of live udp video streams that currently are viewed by set top boxes in my network. I would like to pick this video up (I can do this with vlc now) and stream it out to other non-STB endpoints (webpage or a phone/tablet of some sort). Right now I am able to pick up the udp stream with vlc and convert it to an http stream on port 8080 of my vlc box. Then I can use the vlc client to pick up and watch that video stream. This is where I'm not sure where to go with it. I really doubt I would want everyone who is watching the video to make a connection back to my vlc server that is doing the encoding, so how do I distribute this live video to the people who want to see it?

• MS Office on Virtual Machine (Parallels): licensing

  - by keijo

  I'm running Win XP on Parallels on my two home computers (iMac and macbook pro). I'm planning to buy Office 2010 Student version and install it on my virtual xp:s. How the licensing of MS Office goes on virtual machines? I'm worried about the scenario where I have to re-install virtual machines (which happens some time), and because of that I have to install Office 2010 Student version many times. I think that the licensing of MS Office Student version allows installation only for three times?

• Can I associate my spare Elastic IP addresses to an Amazon EC2 instance started in an Autoscale group and Monitoring?

  - by undefined

  I want to know if I can reserve a number of Amazon Elastic IP addresses and assign them to instances started by Autoscale. So basically, when a new instance is started because a trigger has been triggered can I also set the API to look for a spare IP address and allocate it to the instance. I need to do this because the started instance will need to communicate to a server outside the cloud and get through a firewall which will only allow remote access from a predefined set of IP addresses. So i think i need to reserve some IPs, add them to my firewall settings then allocate them (automatically) when a new instance is started. Any ideas?
